AB  - Climatic change is a serious problem because it can irreversibly modify most ecosystems. Many species try to survive by adapting, through natural selection, to the new climatic conditions. In this scenario, the inversion chromosomal polymorphism of Drosophila subobscura is an excellent natural system through which to study the adaptations of organisms to climatic change. For analyzing the response of inversions to global warming, the chromosomes of annual samples (2019-2022) from a Petnica (Serbia) D. subobscura population were analyzed. These results were compared with those from other populations of this species, but belonging to different climatic regions (Avala, also in Serbia, and Font Groga, Spain). In all cases significant differences were observed, indicating that the inversion composition conferring adaptive capacity to flies in these regions was different. In Petnica, not all inversions responded in the same way to climatic variables: those located in E and U chromosomes presented more changes. Moreover, by comparing data from 2019-2022 with those from a previous sample also from Petnica (1995), it was possible to relate the changes in meteorological variables to frequency variations of 'cold', 'warm', and 'non-thermal'-adapted inversions for these years. These results allow for a better understanding of the genetic adaptations to new environmental conditions.

AB  - Aim Freshwater planarians may have a wide geographical range despite their assumed low vagility. Found across four continents, Dugesia may have either an ancient origin on a large palaeo landmass, followed by colonisation in different regions before continental fragmentation, or a more recent origin and subsequent transoceanic dispersal. We seek to resolve between these two hypotheses. Location Africa, Eurasia and Australasia. Taxon Genus Dugesia (Platyhelminthes: Tricladida: Dugesiidae). Methods We used data from the sequencing of six gene fragments and comprehensive taxonomic sampling of Dugesia from across its distribution range to reconstruct the phylogeny of this genus using maximum likelihood and bayesian inference methods. We conducted two phylogenetic dating analyses using Platyhelminthes fossils and palaeogeological events. Basing on the time-calibrated molecular phylogenetic framework we evaluated the contribution of vicariance and dispersal to the biogeographical evolution of Dugesia. By reconstructing the ancestral areas and present-day potential distribution using BioGeoBEARS and niche modelling, we elucidated the biogeographical history of the genus. Results The present-day distribution of Dugesia is a result of different vicariance and dispersal events. However, we also found evidence of transoceanic dispersal. Consistent with previous hypotheses, Dugesia dates to the Upper Jurassic in the Afro-Malagasy Gondwana region. We unveiled a novel biogeographical scenario for the genus, involving multiple events of colonisation in Eurasia from continental Africa via at least three dispersal routes. Main conclusions Dugesia is an ancient genus having reached its present distribution through a complex history of dispersal and vicariant events following its origin in southern Gondwana. Despite the low vagility of Dugesia, we found evidence of their overseas dispersal.

AB  - The adaptive value of chromosomal inversions continues raising relevant questions in evolutionary biology. In many species of the Drosophila genus, different inversions have been recognized to be related to thermal adaptation, but it is necessary to determine to which specific climatic variables the inversions are adaptive. With this aim, the behavior of thermal adapted inversions of Drosophila subobscura regarding climatic variables was studied in the natural population of Avala (Serbia) during the 2014-2017 period. The results obtained were compared with those previously reported in the Font Groga (Barcelona, Spain) population, which presents different climatic and environmental conditions. In both populations, it was observed that most thermal adapted inversions were significantly associated with the first, second or both principal components, which were related with maximum, minimum and mean temperatures. Moreover, a significant increase over years (2004-2017) for the minimum temperature was detected. In parallel, a significant variation over time in Avala was only observed for the frequencies of 'warm' and 'non-thermal' adapted inversions of the U chromosome. However, stability in the chromosomal inversion polymorphism was observed for the 2014-2017 period which might result from the temporal span of the study and/or selective process acting on the population.

AB  - The changes of chromosomal inversion polymorphism composition of Drosophila subobscura in samples from Apatin (Serbia) were studied in a 24-years interval (1994-2018). The variation was significant for all autosomes and directional, increasing the inversions considered as 'warm', whereas those reported as 'cold' decreased. Furthermore, the Chromosomal Thermal Index (CTI), which allows studying the thermal adaptation of the whole karyotype increased significantly in that period of time. These results were in agreement with the indicators of global warming in Apatin: a trend to increase of the mean, maximum and minimum (this latter even significant) temperatures, and an erratic pattern of rainfall (also usual in global warming). The deviations from the Wright-Fisher model of genetic drift were used to consider the possible effect of migration or selection as evolutionary factors responsible for the change in inversion frequencies. To quantify approximately the rate of change in the frequencies, for each kind of inversions ('cold', 'warm' and 'non-thermal adapted'), the difference in frequency between the Apatin samples obtained in 1994 and 2018 was computed and then it was divided by the number of years elapsed. This rate was always higher (from twice as many as thirty times more depending on the autosome) for thermal adapted inversions ('cold' or 'warm') than the 'non-thermal' adapted. From this study, it could be concluded that the chromosomal inversions of D. subobscura could change (in composition and frequencies) in a predictable direction and a rather 'rapid' rhythm to adapt to the global warming scenario.

AB  - Drosophila has demonstrated to be an excellent model to study the adaptation of organisms to global warming, with inversion chromosomal polymorphism having a key role in this adaptation. Here, we introduce a new index (Chromosomal Thermal Index or CTI) to quantify the thermal adaptation of a population according to its composition of "warm" and "cold" adapted inversions. This index is intuitive, has good statistical properties, and can be used to hypothesis on the effect of global warming on natural populations. We show the usefulness of CTI using data from European populations of D. subobscura, sampled in different years. Out of 15 comparisons over time, nine showed significant increase of CTI, in accordance with global warming expectations. Although large regions of the genome outside inversions contain thermal adaptation genes, our results show that the total amount of warm or cold inversions in populations seems to be directly involved in thermal adaptation, whereas the interactions between the inversions content of homologous and non-homologous chromosomes are not relevant.

AB  - It is generally accepted that chromosomal inversions have been key elements in adaptation and speciation processes. In this context, Drosophila subobscura has been, and still is, an excellent model species due to its rich chromosomal polymorphism. In this species, many analyses from natural populations have demonstrated the adaptive potential of individual inversions (and their overlapped combinations, the so-called arrangements). However, little information is available on the evolutionary role of combinations generated by inversions located in homologous and nonhomologous chromosomes. The aim of this research was to ascertain whether these combinations are also a target for natural selection. For this objective, we have studied the inversion composition of homologous and nonhomologous chromosomes from a D. subobscura sample collected in a well-studied population, Mount Avala (Serbia). No significant deviation from H-W expectations was detected, and when comparing particular karyotypic combinations, likelihood ratios close to 1 were obtained. Thus, it seems that for each pair of homologous chromosomes inversions no deviation from randomness was detected. Finally, no linkage disequilibrium was observed between inversions located in different chromosomes of the karyotype. For all these reasons, it can be assumed that, at the cytological level, the individual inversions rather than their combinations in different chromosomes are the main target of selection.

AB  - To study whether inversions (or arrangements) by themselves or
   karyotypes are the main global warming adaptive target of natural
   selection, two Drosophila subobscura Serbian populations (Apatin and
   Petnica) were re-analyzed using different statistical approaches. Both
   populations were sampled in an approximately 15 years period: Apatin in
   1994 and 2008 + 2009 and Petnica in 1995 and 2010. For all chromosomes,
   the four colleptions studied were in Hardy-Weinberg equilibrium. Thus,
   it seems that inversions (or arrangements) combined at random to
   constitute populations' karyotypes. However, there were differences in
   karyotypic frequencies along the years, although they were significant
   only for Apatin population. It is possible to conclude that inversions
   (or arrangements) are likely the target of natural selection, because
   they presented long-term changes, but combine at random to generate the
   corresponding karyotypic combinations. As a consequence, the frequencies
   of karyotypes also change along time.

AB  - Using a well-adapted Drosophila subobscura population (Avala, Serbia), a
   drastic experiment of inbreeding was carried out to assess whether the
   expected level of homozygosity could be reached or if other evolutionary
   forces affected the process. In general, no significant changes of
   inversion (or arrangement) frequencies were detected after 12
   brother-sister mating generations. Furthermore, no significant
   differences were obtained between observed and expected (under the
   inbreeding model) karyotypic frequencies. Thus, these results seemed to
   indicate that the main evolutionary factor in the experiment was
   inbreeding. However, in the G(12) generation, complete chromosomal
   fixation was reached only in two out of the eight final inbred lines. In
   these lines, the chromosomal compositions were difficult to interpret,
   but they could be likely a consequence of adaptation to particular
   laboratory conditions (constant 18 degrees C, food, light period, etc.).
   Finally, in a second experiment, the inbred lines presented higher
   fertility at 18 degrees C than at 13 degrees C. Also, there was a
   significant line effect on fertility: inbred line number 6 (A(1), J(1),
   U(1) under bar+(2) under bar; U(1) under bar+(2) under bar+(6) under
   bar, E-8, and O (3) under bar (+(4) under bar+(7) under bar)) presented
   the highest values, which maybe the result of an adaptation to
   laboratory conditions. Thus, the results obtained in our experiments
   reflect the adaptive potential of D. subobscura inversions.

AB  - The chromosomal inversion polymorphism of Drosophila subobscura is adaptive to environmental changes. The population of Petnica, Serbia, was chosen to analyze short- and long-term changes in this polymorphism. Short-term changes were studied in the samples collected in May, June, and August of 1995. The inversion polymorphism varied over these months, although various interpretations are possible. To analyze long-term changes, samples obtained in May 1995 and May 2010 were compared. The frequency of the "cold" adapted inversions (A(st), J(st), U-st, E-st, and O-st) decreased and that of the "warm" adapted inversions (A(2), J(1), U1+2, and O3+4) increased, from 1995 to 2010. These changes are consistent with the general increase in temperature recorded in Petnica for the same period. Finally, the possible response of chromosomal polymorphism to global warming was analyzed at the regional level (Balkan peninsula). This polymorphism depends on the ecological conditions of the populations, and the changes observed appear to be consistent with global warming expectations. Natural selection seems to be the main mechanism responsible for the evolution of this chromosomal polymorphism.

These values and those from other Balkan populations studied previously (Petnica, Kamariste, Zanjic and Djerdap) were used to analyze the possible effect of population, year, month and altitude above sea level on lethal chromosomal frequencies. According to ANOVAS no effect were observed. Furthermore, the lethal frequencies of the Balkan populations did not vary according to latitude. This is probably due to the relative proximity and high gene flow between these populations. From a joint study of all the Palearctic D. subobscura populations so far analyzed, it can be deduced that the Balkan populations are located in the central area of the species distribution. Finally, it seems that lethal chromosomal frequencies are a consequence of the genetic structure of the populations. DOI: 10.1134/S1022795411100188

AB  - In this study, chromosomal inversion polymorphism data for a natural population of Drosophila subobscura from a swampy region near the town of Apatin (Serbia) were compared with data for the same population collected approximately 15 years earlier. The pattern of chromosomal inversion polymorphism changed over time. There were significant increases in the frequency of characteristic southern latitude ("warm" adapted) chromosomal arrangements and significant decreases in the frequency of characteristic northern latitude ("cold" adapted) chromosomal arrangements in the O and U chromosomes. The chromosomal arrangements O(3+4) and O(3+4+22) (derived from the O(3+4) arrangement) showed significant increases in 2008 and 2009 with regard to the 1994 sample. There was also a significant increase (similar to 50%) in the U(1+2) arrangement, while U(1+8+2) (a typical southern arrangement) was detected for the first time. Since the Apatin swampy population of D. subobscura has existed for a long time in a stable habitat with high humidity that has not been changed by man our results indicate that natural selection has produced chromosomal changes in response to the increase in temperature that has occurred in the Balkan Peninsula of central southeastern European.

AB  - Here we report the viability of natural chromosomal O-inversion structural homo- and heterokaryotypes in a population of D. subobscura from Avala Mountain, Serbia, subjected to cold and heat stress during spring 2004. These results were compared with those observed in the same population in September 2004. We detected protection of a great number of lethal genes in O-chromosome lethal heterozygous combinations, independently of inversion backgrounds and temperature stress. The positive epistatic interactions of mildly-deleterious genes observed only in O-inversion heterokaryotypes (at distinct temperatures) and lethal genes in O-inversion homokaryotypes (under temperature stress only) could be responsible for reducing the genetic load. The seasonal fluctuations in frequencies of several chromosomal arrangements and karyotypes indicate a seasonal adaptation to changeable environmental conditions. The sample of D. subobscura collected in spring 2004 was tolerant to cold but not to heat, and these results point to tolerance to extreme low temperatures, possibly as a result of natural selection. Also, a non-random distribution of distinct combinations of viability classes among several O-inversion karyotypes (under both optimal conditions and heat stress) was observed. This observation could be taken as evidence of co-adaptation: different capacities of several O-inversion karyotypes with different combinations of genes to tolerate a range of temperatures. We conclude that frequency-dependent and supergene selection are balancing selection mechanisms and are responsible for the protection of chromosomal inversions in natural populations of D. subobscura.

AB  - The interactions of lethal and non-lethal genes and their contributions to the viability of Drosophila inversion karyotypes are not well understood. This is especially true under variable environmental conditions. Here we examine the viability of natural chromosomal O-inversion homo- and heterokaryotypes in a D. subobscura population from Avala Mountain, Serbia. The observations we report were performed at a range of temperatures over several years. The heterotic effect of O-lethal heterozygotes on viability was found to be independent of the effects of inversion backgrounds and temperature. Positive epistatic interactions of lethal, mildly deleterious (subvital) and quasinormal (normal) genes were found in O-inversions in heterokaryotypes but not in homokaryotypes. These interactions were independent of temperature. This finding could explain the limitation of the genetic load in D. subobscura populations. In the population analyzed, annual fluctuations in the frequencies of certain chromosomal arrangements, karyotypes and non-lethal chromosomes under cold-stress temperatures seemed to indicate a correlation between these polymorphisms and environmental conditions. Our results indicate that there is a response in tolerance to extreme temperatures that may be due to natural selection. The differences in mean viability between some O-inversion karyotypic combinations indicate that there are differences in their tolerance to variable temperatures. All our results suggest that both frequency-dependent and supergene selection are mechanisms that protect O-chromosomal inversions. Chromosomal inversions may be genetically differentiated and coadapted complexes in D. subobscura populations.

AB  - Although Drosophila subobscura has been a model organism for European and American population geneticists, little information is available on the genetic structure of its natural populations. In this paper we report the estimates of some population parameters. We have used data from lethal allelism tests in four Balkan populations (Kamariste, Djerdap and Petnica in Serbia and Zanjic in Montenegro). In all populations, lethal genes were found to have a deleterious effect on heterozygotes. The N-e values varied greatly from 370 (Petnica) to 19413 (Kamariste), depending on the habitat conditions and some environmental factors. Finally, gene flow between the Balkan populations was detected by the estimates of N-m (from 4.68 in Petnica to 106.2 in Kamariste) and m (from 0.0041 in Djerdap to 0.0126 in Petnica). These results agree with those obtained in a previous study where the frequencies of allelism between populations were greater than predicted by independently arising lethal genes.

AB  - Chromosomal inversion polymorphism was studied in a natural population of Drosophila subobscura from the Djerdap gorge of the Danube River, which is one of southeastern European continental refugia during the last glaciation period. The existence of changes in chromosomal inversion polymorphism during different periods of time was tested. The observed high abundance of chromosomal arrangements and lower IFR value allowed this population to be classified with central European populations. It was characterized by the O-7 and O3 + 4 + 5 arrangements, not found in other populations from the region analyzed. Within the region studied, the E1 + 2 + 9 + 12 chromosomal arrangement was found, apart from this population from a warm habitat, only in one population from a Mediterranean refugium. Many similarities have been observed between the population from the Djerdap gorge and other populations from the region analyzed, which indicates that postglacial migration may have started from this southeastern European refugium. Seasonal changes in the frequencies of the E-st and O3 + 4 + 7 chromosomal arrangements, E-st and O3 + 4 + 7, being more frequent in spring and in summer, respectively, were found. The changes in the J chromosome (J(st)/J(st)), E chromosome (E-st/E1 + 2 + 9 and E-8/E1 + 2 + 9), and O chromosome (O-st/O3 + 4 + 22; O3 + 4/O3 + 4; and O3 + 4 + 1/O3 + 4 + 7), whose karyotypic combination frequencies were associated with seasonal changes, were also found. These changes are most probably associated with seasonal climatic changes in the population analyzed, which confirms that the chromosomal inversions in D. subobscura are adaptive.

AB  - The influence of epistatic interactions of lethal and non-lethal genes upon viability of Drosophila inversion karyotypes is poorly known. In this paper we present comparative results for viabilities of 21 originally natural O-inversion homo- and 38 heterokaryotypes in a D. subohscura population. We observed strong heterotic effect in viability of O-lethal heterozygotes irrespective of different inversion backgrounds, which indicates a mechanism for protection of a great number of lethal genes. In O-non-lethal heterozygotes the heterotic effect in viability was absent irrespective of different inversion backgrounds. Our results showed a great extent of genetic load and high abundance of O-chromosomal arrangements in the population analyzed. It belongs to the set of central European populations. An epistasis of lethal genes present in O-inversion hetero- and not present in O-inversion homokaryotypes of moderate or low frequencies could be good example for co-adaptation of chromosomal inversions with regard to the genetic load. This represents a more efficient mechanism for limitation of genetic load than alternative mechanisms for protection of lethals. Except for lethal genes, possible epistatic interactions of mildly deleterious (subvital) genes, could also be responsible for limiting the extent of genetic load in natural D. subobscura populations. We demonstrated a non-random distribution of several combinations of viability classes among different O-inversion homo- and heterokaryotypes. As a consequence of that, the viabilities of the O-inversion homokaryotypes compared to heterokaryotypes were significantly higher at low frequencies than in moderate or high frequencies. This shows frequency-dependence as a mechanism of balancing selection for protection of O-chromosomal inversions in natural D. subobscura populations. In addition, the viabilities of the O-inversion homokaryotypes of lower frequency, compared to homokaryotypes of moderate or high frequency, were significantly higher. This again indicates the existence of supergene selection as another mechanism for protection of chromosomal inversions, as co-adapted complexes in natural D. subobscura Populations.

AB  - We have analysed the inversion polymorphism and genetic load of O-chromosomes in three populations of D. subobscura from southeastern Europe. As expected for a central populations the inversion polymorphism was extensive. In a like fashion, the genetic load, in particular the frequency of lethals, was heavy in all three populations. There were significant differences in the frequency of moderately deleterious genes. These differences in viability can be attributed to balancing selection. A comparison of these two kinds of genetic polymorphism indicates that there are differences in mean viability among different gene arrangements of O-chromosomes in the three populations. The differences observed are due to an unequal distribution of various viability classes among O-chromosome gene arrangements. We here show for the first time a specific distribution of lethal genes among these arrangements within the Palearctic distribution area of D. subobscura. The lethal allelism test showed lethals are non-randomly associated with the O-st gene arrangement. The amount of genetic load is heavy in gene arrangements with a high frequency, in comparison with the ones with a low frequency. Lethal genes may be protected in combinations of low and moderate frequency gene arrangements that harbor more lethal genes, as the O-st in the one population. Some arrangements that are less protected against recombination have a higher load than ones that are more protected against recombination. This can be taken as evidence for coadaptation.

abstract = "We have analysed the inversion polymorphism and genetic load of O-chromosomes in three populations of D. subobscura from southeastern Europe. As expected for a central populations the inversion polymorphism was extensive. In a like fashion, the genetic load, in particular the frequency of lethals, was heavy in all three populations. There were significant differences in the frequency of moderately deleterious genes. These differences in viability can be attributed to balancing selection. A comparison of these two kinds of genetic polymorphism indicates that there are differences in mean viability among different gene arrangements of O-chromosomes in the three populations. The differences observed are due to an unequal distribution of various viability classes among O-chromosome gene arrangements. We here show for the first time a specific distribution of lethal genes among these arrangements within the Palearctic distribution area of D. subobscura. The lethal allelism test showed lethals are non-randomly associated with the O-st gene arrangement. The amount of genetic load is heavy in gene arrangements with a high frequency, in comparison with the ones with a low frequency. Lethal genes may be protected in combinations of low and moderate frequency gene arrangements that harbor more lethal genes, as the O-st in the one population. Some arrangements that are less protected against recombination have a higher load than ones that are more protected against recombination. This can be taken as evidence for coadaptation.",

AB  - In populations of D. subobscura. a species that is know for its high chromosomal polymorphism, the O-5 inversion has a rather erratic frequency distribution in the Palearctic region. An O-5 lethal chromosomal line obtained from a Balkan population near Zanjic (South Adriatic, Montenegro, Yugoslavia) was tested for lethal allelism with other O-5 lethal chromosomal lines derived from American (USA and Chile) colonizing populations. and from the French population of Taule, No allelism was found between the Balkan lethal gene and those from America and France. Thus, the lethal genes of the O-5 inversions are not of the same origin and it is most probable that the American colonizations did not start from the Zanjic population The general difference in the chromosomal inversion polymorphism corroborates this conclusion. The cytological analysis confirms the assumption that all O-5 chromosomes studied are identical with respect to breakage points.
