AB  - Eco‐cultural landscapes are assumed to be favorable environments for the persistence of biodiversity, but global change may affect differently their terrestrial and aquatic components. Few long‐term studies have examined how multiple, global change stressors may affect wetland biodiversity in such environments. Facultative paedomorphosis is a spectacular example of intra‐specific variation, in which biphasic (metamorphosing) amphibians coexist with fully aquatic conspecifics that do not metamorphose (paedomorphs). Paedomorphosis is seriously threatened by global change stressors, but it is unknown to what extent traditional management will allow its long‐term persistence. Here, we tested the effects of alien species introductions while taking into account land use and climate changes on the distribution of two polymorphic newt species (Ichthyosaura alpestris and Lissotriton graecus) in Montenegro by using a 68‐yr data set and Bayesian mixed models integrating complex spatial and temporal structures. We found that, despite the persistence of natural landscapes, metamorphs dramatically declined and paedomorphs were nearly extirpated, losing 99.9% of their aquatic area of occupancy and all the major populations. Fish introduction was the main determinant of decline for both phenotypes. Climate and the presence of crayfish further contributed to the decline of metamorphs, which started later and was less dramatic than that of paedomorphs. The near extinction of paedomorphosis on a country‐wide scale shows how invasive species determine broad‐scale impacts, which can be even stronger than other global change stressors, and underlines the need for immediate management actions to avoid the extinction of a unique developmental process, paedomorphosis.

AB  - Ovaj rad predstavlja popis vrsta gmizavaca deponovanih u herpetološkoj zbirci Instituta za Biološka Istraživanja 'Siniša Stanković', Univerziteta u Beogradu. Zbirka se sastoji od 8213 primeraka 65 vrsta gmizavaca sakupljenih iz 23 zemlje. Najveći deo zbirke sadrži materijal sa teritorije bivše Jugoslavije. Vrste zastupljene u zbirci klasifikovane su u okviru 19 porodica (tri u okviru Testudines, osam u okviru Lacertilia i osam u okviru Serpentes). Po broju primeraka, najzastupljenije su porodice Lacertidae (6043 - 73,6 %), Colubridae (612 - 7,5 %) i Viperidae (530 - 6,5 %), dok su porodice Cheloniidae, Chamaeleonidae, Phrynosomatidae, Erycidae i Elapidae zastupljene sa po jednim ili dva primerka. Primerci svih vrsta gmizavaca koji žive u Srbiji postoje u zbirci, kao i većina vrsta karakterističnih za Balkansko poluostrvo. Specifičan značaj zbirke ogleda se u velikim populacionim uzorcima nekoliko vrsta. Osim istorijskog značaja, posebna vrednost herpetološke zbirke ogleda se u tome što deponovan materijal omogućava studije sistematike, distribucije, ekologije, morfologije, konzervacione biologije kao i različitih evolucionih i biogeografskih fenomena (npr. endemizma, intraspecijskog diverziteta, hibridizacije taksona, itd).

AB  - Recent studies on the world reptiles' extinction risks pointed out that
   about 20 \% of species are threatened, with another 20 \% are
   data-deficient following IUCN criteria. IUCN set up criteria for
   assessment of extinction risk at global and regional scales, relying on
   distribution data, population parameters and quantitative analyses. Only
   12 \% of reptilian species were listed as globally threatened upon
   population data. Long-term population studies are time-consuming, thus
   it would be practical to use some other parameters for estimations of
   extinction risks. Threatening level (and extinction risks) of Serbian
   reptiles have never been investigated. We aimed to scrutinize species
   threatening level (thus set up conservation priorities) on the basis of
   distributional, ecological and life-history datasets (DELH). We
   estimated which traits are the most important for the conservation of
   species. Separately, we used IUCN criteria for regional level to assess
   extinction risk and compared them with the results obtained by analyses
   of DELH datasets. The two types of criteria gave similar estimates for
   the chelonian species. In snakes, two species exhibited higher
   conservation scores by DELH than by IUCN criteria, the opposite being
   true for two other species. In lizards, only two species had higher
   extinction risks by IUCN whereas five lizards were more threatened
   according to DELH. Our intention was not discredit the values of IUCN
   criteria for setting regional (or national) extinction risks, but to
   suggest that use of additional features other than IUCN could be
   valuable for estimation of threatening level and setting conservation
   priorities for cases where precise distribution and population data are
   not available.

AB  - Triturus cristatus (Laurenti, 1768) and T. dobrogicus (Kiritzescu, 1903) belong to a monophyletic closely related group of crested newts (Wielstra & Arntzen 2011). Triturus cristatus is widely distributed across Europe, while T. dobrogicus distribution is restricted to the valleys within the Danube River system. Triturus dobrogicus and, to a lesser extent, T. cristatus, inhabit permanent large water bodies T. dobrogicus can be even found in slow running waters (e.g. Arntzen 2003). These two species come in contact and hybridize (Mikuliček et al. 2012) along the contact zone of their ranges, from Ukraine on the east to the Czech Republic on the west (Arntzen et al. 2014). Identifying adults of Triturus species based on external morphology rely on their divergence in body size and shape (e.g., Arntzen & Wallis 1999, Jehle et al. 2011, Vukov et al. 2011), as well as on external qualitative traits (black dots on the ventral side of the head and body), which have been proven to be useful in discrimination of crested newt species (e.g., Arntzen & Wallis 1999). However, little is known about morphological differentiation of crested newt species at the larval stage (Schmidt & Van Buskirk 2005). The Triturus larvae can be easily recognized and distinguished from those of other European newts by having three pairs of external and protruding gills, which extend from either side of the neck like feathery plumes, and by having long toes and tapering tail fin with irregular black spots (Griffiths 1996, Arnold & Ovenden 2002). So far, larvae of crested newt species are considered as being morphologically very similar (Arntzen 2003). Study of variation in body shape among crested newt larvae (Ivanović et al. 2011) found that larvae, like adults and freshly metamorphosed juveniles (Vinšálková & Gvoždík 2007), differentiate in body shape (lateral head shape, interlimb distance). Here, we focused on larval pigmentation patterns of two crested newt species, Triturus cristatus and T. dobrogicus. Such qualitative traits would be helpful in species identification at larval stage.

AB  - Based on 15 parameters related to the distribution, ecology and life
   history traits in all 21 Serbian amphibian species, we considered some
   relevant conservation issues. Due to the exceptionally small range of
   Salamandra atra in Serbia and the high vulnerability of this species to
   external threats, we considered it to be in particular danger. Another
   species, Triturus dobrogicus, which occurs in uniform lowland habitat
   where intense agriculture and amelioration are readily practiced, has
   also been rated as vulnerable in Serbia. Other crested newts (Triturus
   cristatus,T macedonicus and T ivanbureschi), because of the intensive
   loss of aquatic habitats and deterioration of the terrestrial habitats,
   are regarded near threatened. The three remaining species of caudate
   amphibians (Salamandra salamandra, Ichthyosaurus alpestris, and
   Lissotriton vulgaris) do not appear to be in special danger. Among the
   anurans, four species (Pelobates fuscus, Pelobates syriacus, Pelophylax
   lessonae and Rana graeca), for a variety of reasons, are under a
   permanent danger. It seems that the other anurans do not face immediate
   threat.

AB  - Paedomorphosis, the presence of ancestral larval and juvenile traits
   that occur at the descendent adult stage, is an evolutionary phenomenon
   that shaped morphological evolution in many vertebrate lineages,
   including tailed amphibians. Among salamandrid species, paedomorphic and
   metamorphic phenotypes can be observed within single populations
   (facultative paedomorphosis). Despite wide interest in facultative
   paedomorphosis and polymorphism produced by heterochronic changes
   (heterochronic polymorphism), the studies that investigate intraspecific
   morphological variation in facultative paedomorphic species are largely
   missing. By quantifying the cranium size and development (bone
   development and remodeling), we investigated the variation at multiple
   levels (i.e., between sexes, populations and species) of two
   facultatively paedomorphic European newt species: the alpine and the
   smooth newt. The pattern of variation between paedomorphs (individuals
   keeping larval traits at the adult stage) and metamorphs (metamorphosed
   adult individuals) varied between species and among populations within a
   single species. The patterns of variation in size and skull formation
   appear to be more uniform in the alpine than in the smooth newt,
   indicating that developmental constraints differed between species (more
   pronounced in alpine than in smooth newt). Our study shows that the
   cranial skeleton provides detailed insight in the pattern of variation
   and divergence in heterochronic polymorphism within and between species
   and open new questions related to heterochronic polymorphism and
   evolution of cranial skeleton.

AB  - Comparative studies of ontogenies of closely related species provide
   insights into the mechanisms responsible for morphological
   diversification. Using geometric morphometrics, we investigated the
   ontogenetic dynamics of postlarval skull shape and disparity in three
   closely related crested newt species. The skull shapes of juveniles just
   after metamorphosis (hereafter metamorphs) and adult individuals were
   sampled by landmark configurations that describe the shape of the dorsal
   and ventral side of the newt skull, and analyzed separately. The three
   species differ in skull size and shape in metamorphs and adults. The
   ontogenies of dorsal and ventral skull differ in the orientation but not
   lengths of the ontogenetic trajectories. The disparity of dorsal skull
   shape increases over ontogeny, but that of ventral skull shape does not.
   Thus, modifications of ontogenetic trajectories can, but need not,
   increase the disparity of shape. In species with biphasic life-cycles,
   when ontogenetic trajectories for one stage can be decoupled from those
   of another, increases and decreases in disparity are feasible, but our
   results show that they need not occur.

AB  - In this paper we present confirmed and potential distribution ranges of all native Serbian reptile species. The information provided herein presents the combination of the newly collected faunistic data and previously published records. The centres of reptilian diversity in Serbia were evaluated, in order to focus future conservation efforts on the regions of particular importance for the protection of this understudied group of animals. We found four main centres of species richness: three in Metohija and one in Šumadija, with 17-21 species per 50 × 50 km square. Analysis of the similarity of species composition in different regions of Serbia showed that South-eastern Serbia is the most distinct from other regions of Serbia, due to high number of Mediterranean species, with two being found exclusively in that region (E. quatuorlineata and P. najadum). Metohija is also very distinct, due to the highest number of species and significant number of specific (Mediterranean) faunal elements. The remaining geographic regions are grouped into three clusters, with Kosovo-Southern Serbia cluster being especially distinct in the terms of species richness and the presence of Mediterranean species. We also compared Serbian herpetofauna with those in other Balkan countries, considering species' numbers and zoogeographic herpetofaunistic elements. Serbian herpetofauna is closest to the Romanian. Zoogeographic analysis showed that reptilian fauna of Serbia consists of eight chorotypes, with the Eastern-Mediterranean (nine species) and Southern-European (five species) as the most dominant ones.

AB  - Considering the need for an up-to-date overview of the distribution and diversity of amphibians of Serbia, we mapped the species distributions upon current, mostly unpublished, faunistic data. Also, we compared batrachofaunas of Serbia and other Balkan countries in terms of species number and zoogeographic batrachofaunistic elements. With its 21 native species (8 urodeles and 13 anurans), Serbia appears to be the second most diverse country in the Balkans. We found three main centres of species richness in Panonnian and Peripannonian Serbia (with 15-17 species per 50 x 50 km square) which signals urgency for their protection. Serbian batrachofauna is most similar to that of the eastern Balkan countries (Bulgaria and Romania). Zoogeographic analysis showed that amphibian fauna of Serbia consists of six chorotypes, with the central-European and southern-European as the most dominant ones.
AB  - S obzirom na potrebu za najnovijim pregledom distribucije i diverziteta vodozemaca Srbije, u ovom radu prikazane su distribucije vrsta dobijene na osnovu postojećih i velikog broja do sada neobjavljenih faunističkih podataka. Dodatno, poređena je batrahofaunu Srbije i ostalih balkanskih zemalja u odnosu na broj vrsta i zoogeografskih batrahofaunističkih elemenata. Sa 21 autohtonom vrstom (8 vrsta repatih vodozemaca i 13 vrsta bezrepih vodozemaca), Srbija je druga zemlja Balkana po diverzitetu vodozemaca. Utvrđeno je postojanje tri glavna centra diverziteta u Panonskoj i Peripanonskoj Srbiji (sa 15-17 vrsta u okviru 50 × 50 km2) što ukazuje na hitnost uvođenja mera zaštite ovih centara. Batrahofauna Srbije je najsličnija istočnim balkanskim zemljama (Bugarska i Rumunija). Zoogeografska analiza pokazala je da se fauna vodozemaca Srbije sastoji od šest horotipova, sa centralnoevropskim i južnoevropskim kao dominantnim horotipovima.

abstract = "Considering the need for an up-to-date overview of the distribution and diversity of amphibians of Serbia, we mapped the species distributions upon current, mostly unpublished, faunistic data. Also, we compared batrachofaunas of Serbia and other Balkan countries in terms of species number and zoogeographic batrachofaunistic elements. With its 21 native species (8 urodeles and 13 anurans), Serbia appears to be the second most diverse country in the Balkans. We found three main centres of species richness in Panonnian and Peripannonian Serbia (with 15-17 species per 50 x 50 km square) which signals urgency for their protection. Serbian batrachofauna is most similar to that of the eastern Balkan countries (Bulgaria and Romania). Zoogeographic analysis showed that amphibian fauna of Serbia consists of six chorotypes, with the central-European and southern-European as the most dominant ones., S obzirom na potrebu za najnovijim pregledom distribucije i diverziteta vodozemaca Srbije, u ovom radu prikazane su distribucije vrsta dobijene na osnovu postojećih i velikog broja do sada neobjavljenih faunističkih podataka. Dodatno, poređena je batrahofaunu Srbije i ostalih balkanskih zemalja u odnosu na broj vrsta i zoogeografskih batrahofaunističkih elemenata. Sa 21 autohtonom vrstom (8 vrsta repatih vodozemaca i 13 vrsta bezrepih vodozemaca), Srbija je druga zemlja Balkana po diverzitetu vodozemaca. Utvrđeno je postojanje tri glavna centra diverziteta u Panonskoj i Peripanonskoj Srbiji (sa 15-17 vrsta u okviru 50 × 50 km2) što ukazuje na hitnost uvođenja mera zaštite ovih centara. Batrahofauna Srbije je najsličnija istočnim balkanskim zemljama (Bugarska i Rumunija). Zoogeografska analiza pokazala je da se fauna vodozemaca Srbije sastoji od šest horotipova, sa centralnoevropskim i južnoevropskim kao dominantnim horotipovima.",

AB  - Variation in a number of morphological characters were analysed in five populations of Testudo hermanni from Serbia and Montenegro. Tortoises from Serbia appeared significantly larger than those from Montenegro. An insular population of Montenegro was distinct due to its extremely small body size and mass and dark plastral pigmentation. Although the majority of tortoises had the supracaudal scute divided, many tortoises had the scute undivided. Effects of possible genetic divergence and/or adaptation to different environmental conditions on observed morphological variation were discussed.

AB  - In this study, we applied geometric morphometrics to explore variations in the level and pattern of sexual size dimorphism (SSD) and sexual shape dimorphism (SShD) of the ventral cranium in three different Modern Eurasian newt taxa (Ichthyosaura alpestris, Triturus species group and Lissotriton vulgaris). The ventral cranium is the part of the skull that is more directly related to foraging and feeding. Our results indicate that the level and pattern of sexual dimorphism in the ventral cranium differ among Modern Eurasian newt taxa. Regarding sexual dimorphism in skull size, Ichthyosaura alpestris and Triturus species show female-biased patterns (females are larger than males), whereas Lissotriton vulgaris appears to be non-dimorphic in skull size. In I. alpestris and Triturus species, SShD is mostly absent, whereas in L. vulgaris, SShD is more pronounced. A high level of variation between populations in both SSD and SShD indicates that local conditions may have a profound effect on the magnitude and direction of sexual dimorphism. The significant sexual differences in ventral cranium size and shape indicate possible subtle intersexual differences in ecological demands due to diet specialisation, in spite of similar general ecological settings.

AB  - We characterized the adult body form of the crested newt (Triturus cristatus superspecies) and explored its evolution. From seven morphometric traits, we determined that body size, interlimb distance and head width define the body form. None of the morphometric traits showed a phylogenetic signal. Three body-shape morphotypes (Triturus dobrogicus + T. cristatus, Triturus carnifex + Triturus macedonicus and Triturus karelinii + Triturus arntzeni) and three body-size morphotypes (T. dobrogicus, T. cristatus and all other crested newts) could be recognized. The ancestral phenotype (a large body with a short trunk and a wide head) characterized T. karelinii and T. arntzeni. Triturus carnifex and T. macedonicus had a somewhat different phenotype (large body and wide head, accompanied by mild body elongation). The most derived phenotype included body size reduction and more pronounced body elongation in T. cristatus and, especially, in T. dobrogicus. Body elongation occurred by trunk lengthening but not head and tail lengthening. Additionally, contrary to other tetrapods, evolutionary axis elongation in crested newts was followed by a decrease in body size. We advocate the hypothesis that ecology drives the evolution of body form in crested newts.

AB  - Numerous alpine newt (Ichthyosaura alpestris) populations from the Balkans, representing all the previously established phylogeographic lineages, were studied for variations in various morphological characteristics (body size and shape, skull qualitative traits and number of trunk vertebrae). Here, we present a decoupling of morphological and mtDNA phylogeographic substructuring in the alpine newt on the Balkan Peninsula. In sharp contrast to other European newts (Triturus spp., Lissotriton spp.), the vast majority of morphological variation in the alpine newt is concentrated at the population level indicating an in situ morphological diversification. We found that the rate of morphological change is similar to the rate of mtDNA change. We hypothesize that the alpine newts are characterized by non-adaptive morphological evolution.

AB  - Previous data have shown that the Former Yugoslavia had a significant role in exports of land tortoises (Testudo spp.) during the past century. In this paper we present historical exploitation and compare dynamics of the trade in land tortoises in the former Yugoslavia according to Federal Statistical Office and Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) database. Also we examine impact of long-term harvesting on the health of populations by calculating the condition index (CI) in the sample populations of the most common tortoise in the former Yugoslavia (Testudo hermanni). According to the Federal Statistical Office's records of international trade, a total of 2615 metric tonnes of tortoises (T. hermanni and T. graeca) were exported from the Former Yugoslavia within a 41-year period during the 20th century. These exports represented a total of 2.142 million specimens. The quantities of tortoises exported peaked at a value of 236 tons in 1972. Since 1929, tortoises have been exported to 19 countries. The largest importers were Germany, Italy, Belgium-Luxembourg and Great Britain. These countries accounted for 77% of the total exports. We found many discrepancies between official Federal records and CITES records for the period from 1975 onwards. Differences were found in the quantities exported, the identities of the importing counties and their relative shares of the total export of tortoises. The current optimal CI values in examined tortoises suggest a response to overharvesting through density-dependent processes. The paper discusses a current situation in tortoise farming and trade and further perspectives on conservation of tortoise populations in the region of the former Yugoslavia.

AB  - This study deals with the ontogenetic and evolutionary aspects of integration patterns in the limbs of crested newt species, which, like most amphibians, have a biphasic life history with two morphologically distinct stages (larval vs. juvenile and adult) that occupy different environments (aquatic vs. terrestrial). We analyzed the structure and pattern of correlation between limb skeletal elements at three ontogenetic stages (larval, juvenile, and adult) of four closely related species that differ in their preferences of aquatic habitats (more terrestrial and more aquatic). We found dynamic changes in the pattern of morphological integration between successive ontogenetic stages, as well as changes over the course of crested newt phylogeny. Generally, equivalent ontogenetic stages of different species of crested newts show higher concordance in the correlation pattern than successive ontogenetic stages within species. Among species, two opposing correlation patterns were observed: in more terrestrial species, homologous limb elements are less correlated and within-limb elements are more correlated; in aquatic species, the reverse pattern occurs. These results indicate that the function seems to be the covariance-generating factor, which has shaped the patterns of morphological integration of crested newt limbs. J. Exp. Zool. (Mol. Dev.

AB  - Exploring the pattern of size and shape changes during the ontogeny of closely related species is of fundamental importance because it provides an insight into the processes that lead to the evolutionary diversification of body forms and into understanding the adaptations and constraints during growth and development. In this study, we explored the interspecific variation of body size and shape changes during postembryonic development (from the mid-larval period up to the end of metamorphosis) of four crested newt species. We analysed ontogenetic changes in the body size and shape, growth rate and the dynamics of shape variance patterns. We found a consistent pattern of changes in variance across the species studied, with the mid-larval and juvenile stages being highly constrained and canalized and the period of metamorphosis as the most variable stage. The ontogenetic trajectories of larval shape diverge in both the direction and the rate of shape changes along species-specific trajectories. These divergences are concordant with interspecific differences in adult body form and species-specific ecological preferences. However, crested newt species reach the juvenile stage at similar size and shape, indicating that metamorphosis, which is a key point between aquatic and terrestrial morphs, 'resets' the ontogenetic trajectories of larvae. Thus, metamorphosis interrupts the pattern of interspecific divergence, causing species to converge in body form. We speculate that such a pattern of developmental regulation could play crucial roles in the evolution of the body form in amphibians with a biphasic life cycle.

AB  - The Mosor rock lizard (Dinarolacerta mosorensis) is a distinctly flattened endemic species that occupies discontinuously distributed rocky areas at high elevations in the Dinaric Mountains of the Balkans. The body size, age structure, longevity, survival rates and growth patterns of this species were studied using skeletochronology and back-calculation methods. The modal age was found to be 5 years for males and 6 years for females, while the maximal longevity was found to be 9 years in both sexes. The age and body length were positively correlated in both sexes. Both sexes reached maturity at 3 years, with a snout-vent length of 53.3 and 56.5 mm for males and females, respectively. The growth coefficient had significantly higher values in females (0.54) than in males (0.40). The asymptotic size of females was lower (66.01 mm) than that of males (70.82 mm). The growth rate of females decreased soon after maturation whereas males continued to grow for a longer time. Juveniles had lower survival rates than adults (0.5 vs 0.7). The effective age at maturity (13.5 months) was significantly greater than that for the small lacertid lizards living at the low altitudes of a Mediterranean climate, greater than but within the range of values predicted for those living at low altitudes of a temperate climate, and lower than but within the range of values predicted for montane small lacertids.

AB  - We present data on the female reproductive traits of the Balkan wall lizard in the Deliblato Sand, a large continental sandland in the Pannonian area in the northwestern periphery of the species range. The clutch and egg characteristics of the population were investigated on the basis of clutches laid in laboratory conditions by gravid females captured in one locality. Balkan wall lizards produced at least two clutches in a breeding season. Individual females laid clutches of commonly two (range 1-4) eggs. The female body size had no effect on clutch and egg size. There was no trade-off between egg size and clutch size.

AB  - In this article, we explore the possible influences of the developmental and functional relationships between skeletal elements on the pattern of morphological integration in the adult skull of the alpine newt. Like many tailed amphibians, the alpine newt has a biphasic life cycle, which implies the possibility that two distinct sets of constraints on development and function of the cranial skeleton may act at different times. We study how trait covariation, resulting from processes early in development, affects patterns of covariation at the adult stage. We test whether the observed patterns of integration are consistent with those predicted from three a priori hypothesized sources of integration: developmental timing, hormonally mediated growth/remodeling during metamorphosis, and developmental and functional relationships. The analyses of the covariation among the landmarks in the dorsal and ventral alpine newt craniums yield somewhat contrasting results. Our results do not indicate a clear correspondence between the observed variations in the skull shape and any of the three proposed hypotheses. No traceable reflection of hypothesized developmental relationships in the pattern of morphological integration/modularity in the adult skull indicate that covariation structure is continually restructured by overlaying variation introduced through developmental and environmental factors at different stages of development. This finding supports the recently elaborated palimpsest view of morphological integration. Also, our results indicate that the allometry-free shape data have an even higher level of morphological integration than the data that contain the allometric component of the shape variation. J.

AB  - Facultative paedomorphosis, a process in which newt larvae can opt for reproduction before or after metamorphosis, is geographically heterogeneous. Despite numerous ecological studies and recent evidence of declines in paedomorphic populations, however, no attempt to model environmental variables that explain the presence of paedomorphs has been made at a multi-scale level. Our aim was to fill this gap in studying three newt species (Lissotriton vulgaris, Mesotriton alpestris, and Triturus macedonicus) of the Montenegrin karst as model species. To this end, we used multivariate analysis on three scales of habitat: the breeding pond, the land use and the climatologic features. Results show that the study area is both an important hotspot for paedomorphosis and where intraspecific diversity is quickly disappearing (20-47% extirpation) because of fish introductions. Other habitat variables (water permanency, PH or the habitat origin) were shown to act on paedomorphosis but not consistently across species, confirming complexity of the evolutionary and ecological processes. This study appeals for more long-term and detailed landscape studies of polyphenisms, a neglected but promising topic, to better understand and protect alternative modes of development. Particularly, measures should be taken to identify hotspots of intraspecific diversity at a global scale and stop fish introductions before we reach a point of no-return. (C) 2008 Elsevier Ltd.

AB  - Background: Sexual size dimorphism (SSD) is a key evolutionary feature that has been studied in many organisms. In a wide range of species, this pattern is more complex because of polymorphism within each sex. However, it is not known whether the magnitude and direction of SSD could be affected by alternative developmental trajectories within sexes. Our aim was to test whether an intrasexual polymorphism, facultative paedomorphosis (a process in which the development of somatic and gonadal tissues differs in alternative morphs), could affect SSD variation patterns in European newts. Results: We report here the first evidence that SSD varies depending on the paedomorphic or metamorphic ontogenetic pathway. In species with a consistent female-biased SSD, paedomorphosis decreased the SSD level, but did not affect its direction. In species with moderate female-biased SSD or variable SSD patterns, paedomorphosis changed the magnitude, or both the magnitude and the direction, of SSD. Conclusion: Our study highlights the importance of developmental processes for shaping SSD patterns in populations in which contrasting life-history pathways evolved. European newts express different SSD patterns depending on their developmental pathway (i.e., metamorphosis versus paedomorphosis), as well as their species and population. These findings emphasize the importance of studying alternative morphotypes, which are found in a wide range of animal groups, to understand the evolution of SSD.

AB  - When the phenotypic divergence within a monophyletic group is characterised by parallel variation of different phenotypic traits, it is very likely that the environment through constraints and/or selection has affected the developmental pathways simultaneously. Such patterns of phenotypic divergence characterise the phenotypic evolution of the crested newts (Triturus cristatus superspecies). In this study, we have examined interspecific variations in the embryonic development of four crested newt species. The species are similar with respect to some basic developmental traits, some morphologically defined developmental stages and the survival rate during early embryogenesis. However, there is significant variation in the developmental rate, as well as differences in the pattern of correlation amongst analysed life-history and developmental traits. Consistent with previous studies, T. dobrogicus appears to be an outlier species, with the longest embryonic period and a significantly different correlation pattern for early life-history and developmental traits. We suggest that the invasion of a novel aquatic environment by T. dobrogicus resulted in large-scale directional changes in development, which could explain parallel change in numerous phenotypic and life-history traits with a high rate of evolution.

abstract = "When the phenotypic divergence within a monophyletic group is characterised by parallel variation of different phenotypic traits, it is very likely that the environment through constraints and/or selection has affected the developmental pathways simultaneously. Such patterns of phenotypic divergence characterise the phenotypic evolution of the crested newts (Triturus cristatus superspecies). In this study, we have examined interspecific variations in the embryonic development of four crested newt species. The species are similar with respect to some basic developmental traits, some morphologically defined developmental stages and the survival rate during early embryogenesis. However, there is significant variation in the developmental rate, as well as differences in the pattern of correlation amongst analysed life-history and developmental traits. Consistent with previous studies, T. dobrogicus appears to be an outlier species, with the longest embryonic period and a significantly different correlation pattern for early life-history and developmental traits. We suggest that the invasion of a novel aquatic environment by T. dobrogicus resulted in large-scale directional changes in development, which could explain parallel change in numerous phenotypic and life-history traits with a high rate of evolution.",

AB  - We report herein on egg size characteristics (vitellus volume and jelly/vitellus ratio) of 4 crested newt
species (Triturus cristatus superspecies). The key results were as follows: (1) maternal and population effects
on these characteristics were detected, however, the species effect was much more pronounced; (2) in terms of
the vitellus volume, T. karelinii and T. macedonicus had the largest eggs, T. dobrogicus had the smallest, and T.
cristatus had eggs of intermediate size; (3) all species significantly differed in their jelly/vitellus ratio values, with
the lowest ratio in T. macedonicus followed by T. karelinii, T. cristatus, and T. dobrogicus with the highest ratio
value; and (4) the species shared a common allometric slope of the egg volume/body size relationship. The egg
size traits appeared to follow a evolutionary trend similar to that of the morphological and ecological diversity
characteristics.
