AB  - Effective pest management strategies for a targeted pest species must rely on accurate, reliable and reproducible estimates of population dynamics. Importance of such approaches is even more conspicuous when assessing pest's potential to utilize other stored products. Using an experimental evolution approach, we have focused our attention on a common bean pest, the seed beetle (Acanthoscelides obtectus). We looked into the potential to invade and sustain population growth on two suboptimal host plants (chickpeas and mung beans). Such an approach simulates steps of the host-shift process in storages. By analyzing population dynamics during initial encountering with a new host plant, we detected a population drop for both novel hosts. However, transgenerational development in a novel environment resulted in a constant population growth in chickpeas, but not in mung bean populations. Reversal of chickpea selected populations to original host plant has led to a severe decrease in population parameters due to low viability of immatures, while the opposite trend was detected in mung bean populations. This paper highlights the importance of good practice in estimating population dynamics for economically important species. With special emphasis on storage pest species, we discuss how this approach can be useful for estimating invading potential of pest insects.

AB  - Pest species pose one of the biggest threats to global agriculture, economy and human health. Thus, there is ongoing effort to implement pest control techniques that are often costly and detrimental for environment and non-target species. The Trojan Female Technique (TFT) is a novel approach to pest management via control of reproductive output. The goal of the TFT is to use naturally occurring mtDNA mutations which impair male fertility, but have no effects on females, to achieve sustained pest population suppression. Although described in fruit flies, the candidate TFT mutations have not yet been documented in pest species. In order to identify and test possible TFT candidates for biological control of seed beetle Acanthoscelides obtectus, a common pest in legume storages, we expressed four mtDNA haplotypes found in laboratory lines selected for late reproduction/long life alongside nuclear background of wild populations. Analysis of the effect of specific mitotypes on female and male reproductive potential showed significant male-only reduction in fertility in just one mito-nuclear combination. More specifically, the fertility of males carrying MG3a haplotype was reduced for more than 40% relative to MG3a females. This result indicates MG3a as a promising candidate for further development of the TFT in seed beetles.

AB  - Analize unutar - i među - individualnihih razlika morfoloških struktura omogućuju otkrivanje obrazaca fenotipskog variranja, kao i ekološko - evolucionih mehanizama koji dovode do njihove divergencije. U ovoj disertaciji utvrđene su komponente fenotipske varijanse oblika funkcionalno različitih cvetnih organa kod entomofilne biljne vrste Iris pumila L., polimorfne u odnosu na boju cveta. Eksperimenti su vršeni na biljkama gajenim u eksperimentalnoj bašti, poreklom iz recipročnih ukrštanja 24 klonalna genotipa. Metodama geometrijske morfometrije utvrđeni su obrasci variranja oblika tri bilateralno simetrična organa: fola, standarda i grane tučka. Kod sva tri organa udeo simetrične komponente u ukupnom variranju oblika bio je najveći, dok je fluktuirajuća asimetrija (FA) dominirala u asimetričnoj komponenti. Iako se smatra da je primarni uzrok FA nestabilnost razvića, naša istraživanja su pokazala da fenotipska plastičnost može takođe da proizvede FA. Naime, replike cvetnih organa sa različitom orijentacijom prema suncu imale su različite vrednosti asimetričnih komponenti varijanse oblika, kao rezultat plastičnosti u odnosu na mikrosredinsku heterogenost ambijentalne svetlosti. Da veličina, oblik i boja cveta predstavljaju vizuelne signale za privlačenje potencijalnih oprašivača potvrdila su poređenja veličine cvetnih organa oprašenih i neoprašenih biljaka. Oprašeni cvetovi su, po pravilu, imali veće organe od neoprašenih, sa izuzetkom grane tučka. Regresione analize su pokazale da je veličina fola bila pod delovanjem pozitivne, a grane tučka negativne direkcione selekcije. Suprotno tome, oblik cvetnih organa se razlikovao u zavisnosti od boje, što ukazuje da je preferencija oprašivača prema specifičnim kombinacijama vizuelnih signala bila važan mehanizam morfološke divergencije reproduktivnih organa I. pumila.
AB  - Analyzes of intra - and inter - individual differences of morphological structures allow the detection of patterns of phenotypic variation, as well as ecological evolutionary mechanisms leading to their divergence. In this dissertation, components of the phenotypic variation of the shape of functionally distinctive flower organs were determined in the entomophilous plant, specific for striking flower color polymorphism, Iris pumila L. Experiments were carried out on plants grown in experimental garden, originating from reciprocal crossing of 24 clonal genotypes. Using the methods of geometric morphometrics patterns of variation of the shape of three bilaterally symmetrical organs (falls, standards and style branches) have been revealed. In all three floral organs, the proportion of the symmetric component in the overall shape variation was the highest, while the fluctuating asymmetry (FA) was dominated in asymmetric component. Although it is thought that primary cause of FA is developmental instability, our research has shown that phenotypic plasticity can also produce FA. Namely, replicas of flower organs with different orientations towards the sun had different values of asymmetric components of variance of the shape, as an outcome of plasticity in relation to the microenvironmental heterogeneity of ambient light. In this dissertation it is confirmed that size, shape and color of flowers are visual attractants for pollinators. Pairwase comparisons in size between pollinated and unpollinated flowers revealed that pollinated falls and standards are bigger related to their unpollinated pairs. Regression analyzes have shown that the size of the falls was under positive selection, while size of style branches was under negative direct selection. In contrast, the shape of the flower organs differed depending on their color, indicating that the pollinator's preference for specific combinations of visual signals was an important mechanism of morphological divergence of the reproductive organs of I. pumila.

AB  - To predict short-term plant responses to global warming, an open-topped-chamber experiment was conducted in two sun-exposed natural populations of Iris pumila during a growing season. In each population, one half of all randomly selected clonal plants were experimentally warmed using a clear-sided, open-topped chamber (OTC), while the other half experienced the ambient temperature conditions. The air temperature within the OTCs was approx.1-2 ºC higher than that outside of the OTCs in general. In spring and summer of 2018, phenotypic values of the three functional leaf traits: specific leaf area (SLA), leaf dry mass content (LDMC), and leaf water content (LWC) were recorded on the ramets from each clone growing inside and outside of the OTC. The phenotypic expressions of all analyzed traits changed significantly with temperature in both populations, but in an opposite direction. While SLA and LWC tended to be greater in the ramets developing within the OTCs relative to those growing outside of them, their LDMC values reversed, being higher inside than outside of the OTCs. The analyzed traits varied seasonally as well. Regardless of the location within a clone, the values of SLA and LWC were greater in spring then in summer. Conversely, LDMC reached its maximum in the warmer season. Our results clearly suggest that I. pumila plants have the capacity to cope with increasing temperatures by plastic responses of leaf functional traits. This finding is of crucial importance to forecast the fate of Iris populations under global warming - that is, whether they will adopt or disappear.

AB  - Flowers are complex phenotypic structures composed of four functionally distinct organs arranged in concentric floral whorls: sepals in the frst, petals in the second, and two inner whorls
consisting of reproductive structures: stamens in the third whorl and tricarpellary gynoecium, in
the centre. Color, size and shape of these floral organs are considered to be important signals that
can attract the pollinators, advertising the plants’ floral reward (commonly nectar and pollen).
Here we use the methods of geometric morphometrics to compare size and shape variation of
three functionally different floral organs: falls, standards and style arms, among fve distinct color
morphs (blue, violet, dark blue, dark violet and yellow). Pairwise comparisons of the centroid size
means showed that all floral organs differed signifcantly among the analysed color phenotypes.
The mean shape of falls, standards and style arms appeared to be flower color-specifc as well, but
most noticeably between yellow - on one side, and blue/violet morphs - on the other. Procrustes
ANOVAs revealed the signifcant presence of directional and fluctuating asymmetry for falls and
standards among all fve color morphs, with the exception of style arms. The observed morphological diversifcation of floral organs among distinctive I. pumila color phenotypes could be the
adaptive outcome of the interactions with their pollinators.

AB  - Angiosperm flowers serve as an advertisement for pollinators and are, therefore, believed to
be shaped by pollinator-mediated selection. The large flower size, which is one of the distinct
characteristics of the genus Iris, might have evolved under the strong selective pressures imposed
by pollinators, either because larger flowers indicate more rewards or because the pollinators can
detect them from a greater distance. To test the role of visual floral signals in attracting pollinators and, consequently, pollination efciency, we compared the phenotypic expressions of flower
height and centroid size of petaloid floral organs: falls, standards and style arms, as well as anthocyanin absorption between naturally pollinated and non-pollinated flowers of I. pumila plants
grown in a common-garden experiment. Our results indicated that I. pumila pollinators generally
preferred taller flowers with greater organ sizes compared to the alternative ones. However, the
direction of pollinator-mediated selection appeared to be strongly flower organ-specifc: positive
on fall, negative on style arm and neutral on standard size. The observed results are in agreement
with the functions that each of these floral structures has in the pollination process: standards are
a long-distance reward signals, falls are landing platform for pollinating insects, while style arms,
as upper parts of the pollination tunnels, promote pollen deposition. We failed to corroborate the
existence of pollinator-mediated selection on anthocyanin absorption. This suggested that some
other aspects of flower colour might be more attractive to insect pollinators, or that different biotic or abiotic factors could account for the maintenance of flower colour polymorphism in I. pumila.

AB  - Fluctuating asymmetry (FA) is widely used to quantify developmental instability (DI) in ecological and evolutionary studies. It has long been recognized that FA may not exclusively originate from DI for sessile organisms such as plants, because phenotypic plasticity in response to heterogeneities in the environment might also produce FA. This study provides the first empirical evidence for this hypothesis. We reasoned that solar irradiance, which is greater on the southern side than on the northern side of plants growing in the temperate zone of the Northern Hemisphere, would cause systematic morphological differences and asymmetry associated with the orientation of plant parts. We used geometric morphometrics to characterize the size and shape of flower parts in Iris pumila grown in a common garden. The size of floral organs was not significantly affected by orientation. Shape and particularly its asymmetric component differed significantly according to orientation for three different floral parts. Orientation accounted for 10.4% of the total shape asymmetry within flowers in the falls, for 11.4% in the standards and for 2.2% in the style branches. This indicates that phenotypic plasticity in response to a directed environmental factor, most likely solar irradiance, contributes to FA of flowers under natural conditions. That FA partly results from phenotypic plasticity and not just from DI needs to be considered by studies of FA in plants and other sessile organisms.

AB  - The 70kD heat shock proteins (Hsp70s) are highly conserved molecular chaperones that play
essential roles in numerous cellular processes, including the folding of newly synthesized and
stress-denatured proteins, the translocation of proteins across membranes, as well as the degradation of aggregated proteins. Here we examined the variation in the abundance of Hsp70s in
different floral organs of the three distinctive color morphs in Iris pumila. Flowers of twenty seven
genotypes raised in a common-garden and belonging to three colour classes: yellow, dark blue
and dark violet, were collected (9 per each class) for an immunoblot analysis. The content of Hsp70
was quantifed in four floral organs: falls, standards, stamens and style arms. The immunoblot analysis revealed that the expression of Hsp70s was floral organ-specifc. While only one Hsp70 isoform
was expressed in the standards and falls, the stamens and style arms expressed two isoforms. The
relative abundance of Hsp70 varied among differed flower organs as well. The lowest value was
recorded in the standards and the highest in the stamens, whereas its abundance in the falls and
style arms appeared to be intermediate. Such variation pattern was detected exclusively in the
dark violet colour morphs. In the yellow flowers, however, the amount of Hsp70 tended to be lower compared to the dark blue or dark violet colour morphs. This study provides original evidence
for organ-specifc Hsp70 expression in flowers of I. pumila plants, likely due to the differential metabolic activities occurring in the cells of these functionally distinctive floral structures.

AB  - Flavonoids and carotenoids are plant pigments that play a variety of functional roles in higher
plants. Beside their impacts on flower color, they are involved in plant growth, development and
protection against a wide range of environmental stressors. They act either as light attenuators
and free radical scavengers (e.g. anthocyanins) or participate in non-photochemical quenching
(carotenoids). To quantify the accumulation of flavonoids and carotenoids in different floral organs,
ffty Iris pumila genotypes grown in a common-garden and belonging to different color classes
(yellow, blue, violet, dark blue and dark violet) were assessed. One flower per each genotype was
harvested and analyzed spectrophotometrically for the content of three flavonoids (anthocyanins,
flavones, flavonols) and total carotenoids in different floral organs: falls, standards, stamens and
style arms. While the quantity of flavonoids was found to be floral organ- and color morph-specific, the amount of carotenoids varied only among individual floral organs. The variation pattern of
the analyzed compounds displayed identical trend - the lowest amounts were recorded in the stamen and style arm, and the highest in the standard and fall. The content of carotenoids appeared
to be the highest in floral organs of the yellow color morphs, whereas in the blue, violet, dark blue
and dark violet flower phenotypes its abundance was a half of that recorded for the yellow one.
Conversely, the anthocyanin content was rather high in the floral organs of dark violet and dark
blue color morphs, but extremely low in those of the yellow one. Our results clearly suggest that a
greater accumulation of both plant pigments in sterile rather than in fertile flower organs could be
causally related to their specifc function in the process of sexual reproduction, where the former
serve to attract plant pollinators, while the latter promote an efcient pollen deposition.

One flower per each genotype washarvested and analyzed spectrophotometrically for the content of three flavonoids (anthocyanins,flavones, flavonols) and total carotenoids in different floral organs: falls, standards, stamens andstyle arms. While the quantity of flavonoids was found to be floral organ- and color morph-specific, the amount of carotenoids varied only among individual floral organs. The variation pattern ofthe analyzed compounds displayed identical trend - the lowest amounts were recorded in the stamen and style arm, and the highest in the standard and fall. The content of carotenoids appearedto be the highest in floral organs of the yellow color morphs, whereas in the blue, violet, dark blueand dark violet flower phenotypes its abundance was a half of that recorded for the yellow one.Conversely, the anthocyanin content was rather high in the floral organs of dark violet and darkblue color morphs, but extremely low in those of the yellow one. Our results clearly suggest that agreater accumulation of both plant pigments in sterile rather than in fertile flower organs could becausally related to their specifc function in the process of sexual reproduction, where the formerserve to attract plant pollinators, while the latter promote an efcient pollen deposition.

AB  - Community assembly rules have been extensively studied, but its association with regional environmental variation, while land use history remains largely unexplored. Land use history might be especially important in Mediterranean forests, considering their historical deforestation and recent afforestation. Using forest inventories and historical (1956) and recent (2000) land cover maps, we explored the following hypotheses: 1) woody species assembly is driven by environmental factors, but also by historical landscape attributes; 2) recent forests exhibit lower woody species richness than pre-existing due to the existence of colonization credits; 3) these credits are modulated by species’ life-forms and dispersal mechanisms. We examined the association of forest historical type (pre-existing versus recent) with total species richness and that of diverse life-forms and dispersal groups, also considering the effects of current environment and past landscape factors. When accounting for these effects, no significant differences in woody species richness were found between forest historical types except for vertebrate-dispersed species. Species richness of this group was affected by the interaction of forest historical type with distance to coast and rainfall: vertebrate-dispersed species richness increased with rainfall and distance to the coast in recent forests, while it was higher in dryer sites in pre-existing forests. In addition, forest historical types showed differences in woody species composition associated to diverse environmental and past landscape factors. In view of these results we can conclude that: 1) community assembly in terms of species richness is fast enough to exhaust most colonization credit in recent Mediterranean forests except for vertebrate-dispersed species; 2) for these species, colonization credit is affected by the interplay of forest history and a set of proxies of niche and landscape constraints of species dispersal and establishment; 3) woody species assemblage is mostly shaped by the species’ ecological niches in these forests.

AB  - Whether sexual selection generally promotes or impedes population persistence remains an open question. Intralocus sexual conflict (IaSC) can render sexual selection in males detrimental to the population by increasing the frequency of alleles with positive effects on male reproductive success but negative effects on female fecundity. Recent modeling based on fitness landscape theory, however, indicates that the relative impact of IaSC may be reduced in maladapted populations and that sexual selection therefore might promote adaptation when it is most needed. Here, we test this prediction using bean beetles that had undergone 80 generations of experimental evolution on two alternative host plants. We isolated and assessed the effect of maladaptation on sex-specific strengths of selection and IaSC by cross-rearing the two experimental evolution regimes on the alternative hosts and estimating within-population genetic (co)variance for fitness in males and females. Two key predictions were upheld: males generally experienced stronger selection compared to females and maladaptation increased selection in females. However, maladaptation consistently decreased male-bias in the strength of selection and IaSC was not reduced in maladapted populations. These findings imply that sexual selection can be disrupted in stressful environmental conditions, thus reducing one of the potential benefits of sexual reproduction in maladapted populations.

AB  - Introduction: Natural populations of the dwarf bearded iris, Iris pumila, are markedly
polymorphic for flower color. Selection pressures exerted by a range of abiotic and
biotic factors could be involved in maintaining the polymorphism. Here we
quantified the amount of the Hsp70 and the two groups of pigments with
antioxidative properties: anthocyanins and carotenoids.These molecules impact
abiotic stress tolerance, ultimately influencing the fitness of individual plants.
Methods: A total of fifty genotypes raised in a common-garden and belonging to a
corresponding color class (yellow, blue, violet, dark blue and dark violet) were
surveyed. One fully developed leaf and a flower from each genotype were
analyzed for the Hsp70 amount and pigments concentration.
Results: The Western blot analysis revealed the presence of one isoform for the Hsp70
in leaf and two isoforms in flower organs. In both vegetative and reproductive tissues
the amount of Hsp70 was found to be the lowest in yellow colored genotypes
compared to other color classes. In violet and blue flowers, the concentration of
Hsp70 decreased gradually from light to dark colored variants. Conversely, the
concentration of anthocyanins was found to be higher in darker than in the lighter
color morphs. An inverse trend was observed for the total carotenoids
concentration.
Conclusion: This study revealed that each I. pumila color genotype produces a
unique amount of Hsp70 and antioxidative pigments in both the vegetative and
reproductive plant parts, in order to protect cellular homeostasis under fluctuating
temperature conditions prevailing in its population.

AB  - The Iris flower is a complex morphological structure composed of two trimerous whorls of functionally distinct petaloid organs (the falls and the standards), one whorl of the stamens and one tricarpellary gynoecium. The petal-like style arms of the carpels are banded over the basal part of the falls, forming three pollination tunnels, each of which is perceived by the Iris pollinators as a single bilaterally symmetrical flower. Apart from the stamens, all petaloid floral organs are preferentially involved in advertising rewards to potential pollinators. Here we used the methods of geometric morphometrics to explore the shape variation in falls, standards and style arms of the Iris pumila flowers and to disentangle the symmetric and the asymmetric component of the total shape variance. Our results show that symmetric variation contributes mostly to the total shape variance in each of the three floral organs. Fluctuating asymmetry (FA) was the dominant component of the asymmetric shape variation in the falls and the standards, but appeared to be marginally significant in the style arms. The values of FA indexes for the shape of falls (insects' landing platforms) and for the shape of standards (long-distance reward signals) were found to be two orders of magnitude greater compared to that of the style arms. Directional asymmetry appeared to be very low, but highly statistically significant for all analyzed floral organs. Because floral symmetry can reliably indicate the presence of floral rewards, an almost perfect symmetry recorded for the style arm shape might be the outcome of pollinator preferences for symmetrical pollination units.

AB  - Ključna pretpostavka evolucione teorije starenja jeste da opadanje uzrasno-specifičnog preživljavanja organizama predstavlja rezultat smanjenja intenziteta prirodne selekcije nakon početka reprodukcije. U osnovi evolucije starenja nalaze se dva populaciono-genetička mehanizma: akumulacija mutacija (AM) i antagonistička plejotropija (AP). U skladu sa pretpostavkama evolucione teorije starenja, kod eksperimentalnih populacija pasuljevog žiška (Acanthoscelides obtectus) selektovanih više od 170 generacija za ranu (E režim) ili kasnu (L režim) reprodukciju, uočena je divergencija u dužini života i drugim preadultnim i adultnim osobinama životne istorije. Evolucija veće dužine života u L režimu u saglasnosti je sa pretpostavkama AP modela, dok u evoluciji kraćeg života E žižaka važnu ulogu ima akumulacija mutacija. Tretiranjem E i L žižaka pesticidima (parakvat i tebufenpirad) koji generišu slobodne radikale, potvrđena je pozitivna korelacija između dužine života i otpornosti na oksidativni stres. Budući da mitohondrija predstavlja glavno mesto sinteze energije i slobodnih radikala, u ovoj tezi je istraženo da li je uzrasno-specifična selekcija oblikovala varijabilnost mtDNK, nDNK i njihovih epistatičkih interakcija. Genotipizacijom mitohondrijskog COI gena i mikrosatelitskih lokusa pokazana je efikasnost uzrasno-specifične selekcije u međupopulacionoj divergenciji mitohondrijskog i jedarnog genskog pula kod pasuljevog žiška. Odvijanje procesa mito-jedarne koevolucije analizirano je korišćenjem mito-jedarnih linija u kojima su E i L mitohondrijski genomi kombinovani sa E i L jedarnim genomima.

AB  - According to the evolutionary theory of ageing, age-specific decline in survival is the result of decreasing intensity of natural selection after the onset of reproduction. The evolution of ageing may be explained by two different, but not mutually exclusive, genetic mechanisms: antagonistic pleiotropy (AP) and mutation accumulation (MA). In accordance with evolutionary theory of ageing, two sets of the seed beetle (Acanthoscelides obtectus) experimental lines selected for more than 170 generations for early (E regime) or late (L regime) reproduction, show divergence in longevity and ageing patterns, as well as in other preadult and adult life history traits. Evolution of long life in L regime is predominantly based on antagonistic pleiotropy gene effects, while mutation accumulation plays important role in evolution of short life in E regime. By exposure of E and L beetles to two pesticides (paraquat and tebufenpyrad) that generate free radicals, it was confirmed that extended longevity in L beetles (especially in females) was associated with higher oxidative stress resistance. Additionally, since mitochondria are main site of free radical and energy production, effects of age-specific laboratory selection on mtDNA, nDNA and their epistatic interaction were assessed. Genotyping of mitochondrial COI gene and nuclear microsatellite loci showed that selection in E and L regimes led to divergent evolution of mtDNA and nDNA gene pools. Mitonuclear coevolution was investigated using mitonuclear introgression lines in which E and L mitochondrial genomes were expressed in both E and L nuclear background. It was found that lines with disrupted mitonuclear interactions had lower activity of the mitochondrial electron transport chain complexes and lower preadult performance.

abstract = "Ključna pretpostavka evolucione teorije starenja jeste da opadanje uzrasno-specifičnog preživljavanja organizama predstavlja rezultat smanjenja intenziteta prirodne selekcije nakon početka reprodukcije. U osnovi evolucije starenja nalaze se dva populaciono-genetička mehanizma: akumulacija mutacija (AM) i antagonistička plejotropija (AP). U skladu sa pretpostavkama evolucione teorije starenja, kod eksperimentalnih populacija pasuljevog žiška (Acanthoscelides obtectus) selektovanih više od 170 generacija za ranu (E režim) ili kasnu (L režim) reprodukciju, uočena je divergencija u dužini života i drugim preadultnim i adultnim osobinama životne istorije. Evolucija veće dužine života u L režimu u saglasnosti je sa pretpostavkama AP modela, dok u evoluciji kraćeg života E žižaka važnu ulogu ima akumulacija mutacija. Tretiranjem E i L žižaka pesticidima (parakvat i tebufenpirad) koji generišu slobodne radikale, potvrđena je pozitivna korelacija između dužine života i otpornosti na oksidativni stres. Budući da mitohondrija predstavlja glavno mesto sinteze energije i slobodnih radikala, u ovoj tezi je istraženo da li je uzrasno-specifična selekcija oblikovala varijabilnost mtDNK, nDNK i njihovih epistatičkih interakcija. Genotipizacijom mitohondrijskog COI gena i mikrosatelitskih lokusa pokazana je efikasnost uzrasno-specifične selekcije u međupopulacionoj divergenciji mitohondrijskog i jedarnog genskog pula kod pasuljevog žiška. Odvijanje procesa mito-jedarne koevolucije analizirano je korišćenjem mito-jedarnih linija u kojima su E i L mitohondrijski genomi kombinovani sa E i L jedarnim genomima. Pokazano je da su linije sa narušenim mito-jedarnim interakcijama imale niže aktivnosti mitohondrijskih kompleksa elektron transportnog lanca i lošiju preadultnu performansu., According to the evolutionary theory of ageing, age-specific decline in survival is the result of decreasing intensity of natural selection after the onset of reproduction.

AB  - Morphological integration, the covariation among phenotypic traits generated by common development and function, has been in the scope of evolutionary research for decades. As a morphological structure with complex development and various functions, the cranial skeleton represents a particularly interesting model for studies on morphological integration. However, most of the empirical investigations were done on akinetic and compact cranial skeletons of mammals. Here, we explore the pattern of integration in the extremely kinetic cranial skeleton of two closely related snake species, Natrix natrix and N. tessellata (Natricinae, Colubridae). In snakes, elements of jaws and palates on the left and right side are not spatially connected or firmly fused, allowing independent motion. Spatial independence of skeletal elements on the left and right side and their functional interconnections with extreme kinetic abilities, provide unique feeding performance in this group of tetrapods. By comparing patterns of symmetric and asymmetric components of variation we analysed cavariation patterns between kinetic and akinetic cranial elements. We tested whether the functionally and spatially connected bones are more integrated than disconnected ones and we examine impact of development and function on the morphological integration. We also explored whether and how allometry affects morphological integration in the snake's skull. Using micro-CT scanning 3D geometric morphometrics we showed strong covariation between the braincase and elements of the feeding apparatus, and that spatially disconnected elements are not more integrated than the connected ones. We also showed that function is the main factor that generates the pattern of morphological integration, because the signal of developmental integration is very weak and probably masked by strong functional integration of skeletal elements. Allometry has a significant impact on the morphological integration, by increasing integration of the skull, particularly integration of the lower jaw bones (compound and dentary), prefrontal, palatine and quadrate with the other skeletal elements. © 2017 The Zoological Society of London.

AB  - Metabolic rate (MR) is a key functional trait simply because metabolism converts resources into population growth rate. Yet, our empirical understanding of the sources of within species variation in MR, as well as of its life history and ecological correlates, is rather limited. Here, we assess whether MR lies at the root of a syndrome of correlated rate-dependent life-history traits in an insect. Selection for early (E) or late (L) age-at-reproduction for > 160 generations in the bean beetle Acanthoscelides obtectus has produced beetles that differ markedly in juvenile development, body size, fecundity schedules, ageing and life span. Here, we use micro-respirometry to test whether this has been associated with the evolution of age- and sex-specific metabolic phenotypes. We find that mass-specific MR is 18% higher in E lines compared to L lines and that MR decreases more rapidly with chronological, but not biological, age in E lines. Males, under sexual selection to "live-fast-die-young", show 50% higher MR than females and MR decreased more rapidly with age in males. Our results are consistent with a central role for MR for the divergence in "pace-of-life" seen in these beetles, supporting the view that MR lies at the root of ecologically relevant life-history trait variation within species.

AB  - Mitochondria play a key role in ageing. The pursuit of genes that regulate variation in life span and ageing have shown that several nuclear-encoded mitochondrial genes are important. However, the role of mitochondrial encoded genes (mtDNA) is more controversial and our appreciation of the role of mtDNA for the evolution of life span is limited. We use replicated lines of seed beetles that have been artificially selected for long or short life for >190 generations, now showing dramatic phenotypic differences, to test for a possible role of mtDNA in the divergent evolution of ageing and life span. We show that these divergent selection regimes led to the evolution of significantly different mtDNA haplotype frequencies. Selection for a long life and late reproduction generated positive selection for one specific haplotype, which was fixed in most such lines. In contrast, selection for reproduction early in life led to both positive selection as well as negative frequency-dependent selection on two different haplotypes, which were both present in all such lines. Our findings suggest that the evolution of life span was in part mediated by mtDNA, providing support for the emerging general tenet that adaptive evolution of life-history syndromes may involve mtDNA.

AB  - Većina dosadašnjih istraživanja strukture i obrazaca varijabilnosti glavenog skeleta
odnosila su se na grupe sa akinetičkom lobanjom. Istraživanje kinetizma u okviru
glavenog skeleta zmija može doprineti boljem razumevanju odnosa razvojne i
funkcijske integracije, uticaja alometrije na varijabilnost oblika i morfološku integraciju
glavenog skeleta, promena oblika tokom ontogenije, kao i morfološke divergencije
između polova. Pored toga, analizama varijabilnosti pileusa može se steći uvid u opštu
sliku varijabilnosti glavenog regiona. Osnovni zadatak ove disertacije je utvrđivanje
obrazaca morfološke varijabilnosti i faktora koji utiču na varijabilnost glavenog skeleta
i pileusa kod dve sestrinske vrste zmija iz roda Natrix (belouške, N. natrix i ribarice, N.
tessellata) primenom metoda kompjuterizovane tomografije i geometrijske
morfometrije. Rezultati su pokazali da se belouška i ribarica razlikuju u veličini i obliku
elemenata glavenog skeleta. Uočene razlike najverovatnije odslikavaju razlike u tipu i
veličini plena, sredini u kojoj love, strategijama lova i sposobnostima držanja i gutanja
plena. Polni dimorfizam u veličini i obliku elemenata glavenog skeleta veoma je izražen
kod belouške i ribarice. Kod obe vrste moždana čaura i elementi trofičkog aparata su
visoko integrisani, dok se kosti njuške ponašaju kao zasebni moduli. Funkcija najviše
doprinosi integrisanosti elemenata glavenog skeleta. Utvrđeno je da se tek rođene
belouške i ribarice razlikuju u obliku pileusa, dok se unutar vrsta polni dimorfizam u
obliku pileusa ispoljava tek kod adulata. Između moždane čaure i pileusa ustanovljeni
su visoki nivoi korelisanosti, kako za veličinu, tako i za oblik.
AB  - Most of the previous investigations on the structure and patterns of cranial skeletons
variability were done in groups with akinetic skull. Research of snake’s kinetic cranial
skeleton can provide a better understanding of the relationship between developmental
and functional integration, influence of allometry on shape variation and morphological
integration of the cranial skeleton, shape changes during ontogeny, as well as
morphological divergence between the sexes. In addition, analysis of pileus variability
may provide insight into general pattern of head variability. The main aim of this thesis
was to define the patterns of morphological variability and factors that affect the
variability of head skeleton and pileus in two sister snakes species from the genus
Natrix (Grass snake, N. natrix and Dice snake, N. tessellata) using the methods of
computed tomography and geometric morphometrics. The results showed that N. natrix
and N. tessellata differ in size and shape of cranial elements. Observed differences
probably reflect differences in the type and size of the prey, hunting environment and
strategies, handling abilities and prey swallowing. Sexual dimorphism in size and shape
of cranial elements are pronounced among Grass and Dice snakes. In both species,
braincase and elements of the trophic apparatus are highly integrated, while the bones of

abstract = "Većina dosadašnjih istraživanja strukture i obrazaca varijabilnosti glavenog skeleta
odnosila su se na grupe sa akinetičkom lobanjom. Istraživanje kinetizma u okviru
glavenog skeleta zmija može doprineti boljem razumevanju odnosa razvojne i
funkcijske integracije, uticaja alometrije na varijabilnost oblika i morfološku integraciju
glavenog skeleta, promena oblika tokom ontogenije, kao i morfološke divergencije
između polova. Pored toga, analizama varijabilnosti pileusa može se steći uvid u opštu
sliku varijabilnosti glavenog regiona. Osnovni zadatak ove disertacije je utvrđivanje
obrazaca morfološke varijabilnosti i faktora koji utiču na varijabilnost glavenog skeleta
i pileusa kod dve sestrinske vrste zmija iz roda Natrix (belouške, N. natrix i ribarice, N.
tessellata) primenom metoda kompjuterizovane tomografije i geometrijske
morfometrije. Rezultati su pokazali da se belouška i ribarica razlikuju u veličini i obliku
elemenata glavenog skeleta. Uočene razlike najverovatnije odslikavaju razlike u tipu i
veličini plena, sredini u kojoj love, strategijama lova i sposobnostima držanja i gutanja
plena. Polni dimorfizam u veličini i obliku elemenata glavenog skeleta veoma je izražen
kod belouške i ribarice. Kod obe vrste moždana čaura i elementi trofičkog aparata su
visoko integrisani, dok se kosti njuške ponašaju kao zasebni moduli. Funkcija najviše
doprinosi integrisanosti elemenata glavenog skeleta. Utvrđeno je da se tek rođene
belouške i ribarice razlikuju u obliku pileusa, dok se unutar vrsta polni dimorfizam u
obliku pileusa ispoljava tek kod adulata. Između moždane čaure i pileusa ustanovljeni
su visoki nivoi korelisanosti, kako za veličinu, tako i za oblik., Most of the previous investigations on the structure and patterns of cranial skeletons
variability were done in groups with akinetic skull. Research of snake’s kinetic cranial
skeleton can provide a better understanding of the relationship between developmental
and functional integration, influence of allometry on shape variation and morphological
integration of the cranial skeleton, shape changes during ontogeny, as well as
morphological divergence between the sexes. In addition, analysis of pileus variability
may provide insight into general pattern of head variability. The main aim of this thesis
was to define the patterns of morphological variability and factors that affect the
variability of head skeleton and pileus in two sister snakes species from the genus
Natrix (Grass snake, N. natrix and Dice snake, N. tessellata) using the methods of
computed tomography and geometric morphometrics. The results showed that N. natrix
and N. tessellata differ in size and shape of cranial elements. Observed differences
probably reflect differences in the type and size of the prey, hunting environment and
strategies, handling abilities and prey swallowing. Sexual dimorphism in size and shape
of cranial elements are pronounced among Grass and Dice snakes. In both species,
braincase and elements of the trophic apparatus are highly integrated, while the bones of
the snout can be considered as separate modules. The function is the main factor of
morphological integration between cranial elements. Hatchlings of Grass and Dice
snakes differed in pileus shape, while sexual dimorphism in pileus shape was detected
in adults only. For both size and shape, high levels of correlation between braincase and
pileus were estimated.",

AB  - High solar radiation has been recognized as one of the main causes of the overproduction of reactive oxygen species (ROS) and oxidative stress in plants. To remove the excess of ROS, plants use different antioxidants and tune their activity and/or isoform number as required for given light conditions. In this study, the adaptiveness of light-induced variation in the activities and isoform patterns of key enzymatic antioxidants SOD, APX and CAT was tested in leaves of Iris pumila clonal plants from two natural populations inhabiting a sun exposed dune site and a forest understory, using a reciprocal-transplant experiment. At the exposed habitat, the mean enzymatic activity of total SODs was significantly greater than that in the shaded one, while the amount of the mitochondrial MnSOD was notably higher compared to the plastidic Cu/ZnSOD. However, the number of Cu/ZnSOD isoforms was greater in the forest understory relative to the exposed site (three vs. two, respectively). An inverse relationship recorded between the quantities of MnSOD and Cu/ZnSOD in alternative light habitats might indicate that the two enzymes compensate each other in maintaining intracellular ROS and redox balance. The adaptive population differentiation in APX activity was exclusively recorded in the open habitat, which indicated that the synergistic effect of high light and temperature stress could be the principal selective factor, rather than high light alone. The enzymatic activity of CAT was similar between the two populations, implicating APX as the primary H2O2 scavenger in the I. pumila leaves exposed to high light intensity.

AB  - The role of mitochondrial DNA for the evolution of life-history traits remains debated. We examined mitonuclear effects on the activity of the multisubunit complex of the electron transport chain (ETC) involved in oxidative phosphorylation (OXPHOS) across lines of the seed beetle Acanthoscelides obtectus selected for a short (E) or a long (L) life for more than >160 generations. We constructed and phenotyped mitonuclear introgression lines, which allowed us to assess the independent effects of the evolutionary history of the nuclear and the mitochondrial genome. The nuclear genome was responsible for the largest share of divergence seen in ageing. However, the mitochondrial genome also had sizeable effects, which were sex-specific and expressed primarily as epistatic interactions with the nuclear genome. The effects of mitonuclear disruption were largely consistent with mitonuclear coadaptation. Variation in ETC activity explained a large proportion of variance in ageing and life-history traits and this multivariate relationship differed somewhat between the sexes. In conclusion, mitonuclear epistasis has played an important role in the laboratory evolution of ETC complex activity, ageing, and life histories and these are closely associated. The mitonuclear architecture of evolved differences in life-history traits and mitochondrial bioenergetics was sex-specific.

AB  - Expansion of the host range in phytophagous insects depends on their ability to form an association with a novel plant through changes in host-related traits. Phenotypic plasticity has important effects on initial survival of individuals faced with a new plant, as well as on the courses of evolutionary change during long-term adaptation to novel conditions. Using experimental populations of the seed beetle that evolved on ancestral (common bean) or novel (chickpea) host and applying reciprocal transplant at both larval and adult stage on the alternative host plant, we studied the relationship between the initial (plastic) phases of host-shift and the subsequent stages of evolutionary divergence in life-history strategies between populations exposed to the host-shift process. After 48 generations, populations became well adapted to chickpea by evolving the life-history strategy with prolonged larval development, increased body mass, earlier reproduction, shorter lifespan and decreased plasticity of all traits compared with ancestral conditions. In chickpea-adapted beetles, negative fitness consequences of low plasticity of pre-adult development (revealed as severe decrease in egg-to-adult viability on beans) exhibited mismatch with positive effects of low plasticity (i.e. low host sensitivity) in oviposition and fecundity. In contrast, beetles adapted to the ancestral host showed high plasticity of developmental process, which enabled high larval survival on chickpea, whereas elevated plasticity in adult behaviour (i.e. high host sensitivity) resulted in delayed reproduction and decreased fecundity on chickpea. The analysis of population growth parameters revealed significant fluctuation during successive phases of the host-shift process in A. obtectus.
