Abstract

Aim: Ecological niche‐based models (ENM) frequently rely on bioclimatic variables (BioV) to reconstruct biogeographic scenarios for species evolution, ignoring mechanistic relations. We tested if climatic predictors relevant to species hydric and thermal physiology better proximate distribution patterns and support location of Pleistocene refugia derived from phylogeographic studies. Location: The Western Palaearctic. Taxon: Vipera berus and Zootoca vivipara, two cold‐adapted species. Methods: We used two sets of variables, that is physiologically meaningful climatic variables (PMV) and BioV, in a multi‐algorithm ENM approach, to compare their ability to predict current and Last Glacial Maximum (LGM) species ranges. We estimated current and LGM permafrost extent to address spatially the cold hardiness dissimilarity between both species. Results: PMV explained more accurately the current distribution of these two cold‐adapted species and identified the importance of summer temperature and solar radiation that constrain activity in cold habitats. PMV also provide a better insight than BioV predictors on LGM distribution. By including notably, the permafrost extent, PMV‐based models gave parsimonious putative arrangement and validity of refugia for each clade and subclade in accordance with phylogeographic data. Northern refugia were also identified from 48 to 52° N for V. berus and from 50 to 54° N for Z. vivipara. Main Conclusions: Our hybrid approach based on PMV generated more realistic predictions for both current (biogeographical validation) and past distributions (phylogeographic validation). By combining constraints during the activity period (summer climatic niche) and those inherent to the wintering period (freeze tolerance), we managed to identify glacial refuges in agreement with phylogeographic hypotheses concerning post‐glacial routes and colonization scenarios.

Abstract

Aim: The development of natural habitats into urban land uses has greatly accelerated in the recent past due to human activities. This habitat development disrupts species' natural dispersal processes and can lead to both direct and indirect impacts on dispersal. Whether human activities result in restricted or facilitated dispersal may depend on a species' development tolerance; however, this premise has not been tested. We examined the impact of urbanization and road networks on the dispersal of three lizard species in the context of their development tolerance. Location: Curaçao. Methods: To quantify species' development tolerance, we modelled three lizard species abundances at sites based on surrounding landscape development. Using microsatellite genotypes, we conducted individual‐based resistance surface analyses and modelled the effect of habitat development on genetic admixture to assess indirect dispersal restriction and facilitation. We explored direct facilitation of dispersal using network analysis of mitochondrial haplotypes. Results: Phyllodactylus martini, a native gecko species, was the least tolerant of development and experienced indirect dispersal restriction due to roads, according to resistance surface analyses. Anolis lineatus, a native anole species, exhibited a neutral relationship with development. Resistance surfaces and Structure analyses showed that A. lineatus faced indirect dispersal restrictions from roads and developed areas, while mitochondrial haplotype networks suggested they benefited from occasional human‐facilitated long‐distance dispersal events. Hemidactylus mabouia, an introduced gecko species, was the most tolerant of development, and experienced no dispersal restriction, but mitochondrial haplotypes suggest direct long‐distance dispersal facilitation. Main Conclusions: Our findings highlight development tolerance as a key predictor of dispersal impact for these species and future work should test whether these patterns are upheld in other systems. Understanding how human activities affect species' dispersal will aid in managing introduced species while promoting connectivity for native species navigating dispersal challenges in dynamic landscapes.

Abstract

Floral divergence can contribute to reproductive isolation among plant lineages, and thus provides an opportunity to study the genetics of speciation, including the number, effect size, mode of action and interactions of quantitative trait loci (QTL). Moreover, flowers represent suites of functionally interrelated traits, but it is unclear to what extent the phenotypic integration of the flower is underlain by a shared genetic architecture, which could facilitate or constrain correlated evolution of floral traits. Here, we examine the genetic architecture of floral morphological traits involved in an evolutionary switch from bill to forehead pollen placement between two species of hummingbird‐pollinated Neotropical understorey herbs that are reproductively isolated by these floral differences. For the majority of traits, we find multiple QTL of relatively small effect spread throughout the genome. We also find substantial colocalization and alignment of effects of QTL underlying different floral traits that function together to promote outcrossing and reduce heterospecific pollen transfer. Our results are consistent with adaptive pleiotropy or linkage of many co‐adapted genes, either of which could have facilitated a response to correlated selection and helped to stabilize divergent phenotypes in the face of low levels of hybridization. Moreover, our results indicate that floral mechanical isolation can be consistent with an infinitesimal model of adaptation. see also the Perspective by Carolyn A. Wessinger [ABSTRACT FROM AUTHOR]

Abstract

International audience; Eight populations of the sand lizard (Lacerta agilis) from Poland (allozymes and cytochrome b gene sequences) and 18 populations from Poland, Slovakia, Austria, Hungary, Croatia, Italy, France and Russia (dloop region sequence) were studied. The level of allozyme polymorphism is very low. It was only found in two loci of two enzyme systems (MOD and PGD) among the 8 loci studied and only in two populations from North-Eastern and Central-Eastern Poland. Bayesian Inference and additional phylogenetic analyses basing on cytochrome b gene and dloop region indicate clearly that haplotypes from these two populations form a separate clade. The study confirms the homogenity of sand lizard populations in Central Europe (L. agilis argus) except for populations from NE and E of Poland (L. agilis chersonensis). Dloop analysis suggests the position of sand lizard from Croatia as L. agilis bosnica.

Abstract

revue non indexee; Knowledge on variations in the reproductive modes, karyotypes, and mtDNA sequences of Lacerta (Zootoca) vivipara made headway but the morphological differences between any forms or populations remain unclear. That is why we studied different patterns of morphological variability using nine biometrics and 10 meristic variables on 242 common lizards: 119 oviparous (French, Spanish, and Slovenian), 114 viviparous (French, Bulgarian, and Russian), and nine hybrids. Our analyses confirm, for each population, the existence of a clear sexual dimorphism. Observed differences between reproductive strains (oviparous vs. viviparous) could not be connected immediately with the reproductive mode. Results of comparison between regions correspond to the geographical origin of the samples. We observe three clusters: western (Pyrenees and France), Slovenian, and eastern (Bulgaria, Russia, and Siberia). Comparisons of samples defined by their karyotypes are very similar. L. (Z.) v. carniolica subspecies is different for a majority of the studied variables. Our results show the special interest of the Russian samples but do not support the validity of the sachalinensis subspecies. The absence of clear relation between morphological and genetic structure of the species reveals that samples of the “complex” of common lizards are very closely related and have likely relatively recently diverged.

Abstract

The lizard Lacerta (Zootoca) vivipara, which is viviparous in the greatest part of its distribution range, has however some oviparous populations on the southern margin of its range. The present study aimed at determining the reproductive mode and the ATA (aspartate transaminase) enzyme characteristics of four populations in Slovenia and one population in Croatia. The Slovenian females studied here presented an oviparous reproductive mode which strongly resembled those observed in the oviparous populations of south-western France and north-western Spain. Our electrophoresis analyses revealed the existence of two distinct alleles, ATA–150 and ATA–200, in the oviparous populations of Slovenia. These alleles were identical to those observed in the French and Spanish oviparous group and were distinct from the allele ATA–100 characterizing the viviparous populations that we had previously studied. Although we did not study the reproductive mode of Croatian females, the allele ATA–200 observed in one population of Croatia strongly suggested that this population might also be oviparous.
