Despite hundreds of reports involving both plants and animals, the mechanisms underlying introgression remain obscure, even if some form selection is frequently invoked. Introgression has repeatedly been reported in species that have recently colonized a new habitat, suggesting demographic processes should be given more attention for understanding introgression. Here we show by spatially explicit simulations massive neutral genes takes place during invasion an occupied territory...

We investigate the contribution of Iberian bat fauna to cryptic diversity in Europe using mitochondrial (cytb and ND1) nuclear (RAG2) DNA sequences. For each 28 species known for Iberia, samples covering a wide geographic range within Spain were compared from rest Europe. In this general screening, almost 20% showed important discontinuities (K2P distance values > 5%) either or between other European samples. Within Eptesicus serotinus Myotis nattereri, levels genetic divergence lineages...

The two sibling bat species Myotis myotis and blythii occur in sympatry over wide areas of Southern Central Europe. Morphological, ecological previous genetic evidence supported the view that constitute well-differentiated groups, but recent phylogenetic analyses have shown share some mtDNA haplotypes when they sympatry. In order to see whether exchange has occurred between species, we sequenced a highly variable segment mitochondrial control region both living allopatry. We also analysed...

In Southeast Asia, bats of the genus Tylonycteris Peters, 1872 have traditionally been classified into two wide-ranging species, T. pachypus (Temminck, 1840) and robustula Thomas, 1915. Our comparative phylogeographic analyses based on mitochondrial seven nuclear genes, combined with our multivariate morphological analyses, show that these species actually represent cryptic complexes share a similar biogeographic history in three major regions, i.e., Sundaland, southern Indochina, northern...

The emergence of COVID-19 and severe acute respiratory syndrome (SARS) has prioritized understanding bats' viral tolerance. Myotis bats are exceptionally species rich have evolved They also exhibit swarming, a cryptic behavior where large, multi-species assemblages gather for mating, which been hypothesized to promote interspecific hybridization. To resolve the coevolution genome architecture their unusual antiviral tolerance, we undertook phylogenomic analysis 60 Old World genomes. We...

Abstract Thirteen nursery colonies of Myotis myotis were sampled in central Europe to investigate the dispersal behaviour this bat species. Mitochondrial DNA sequences 260 bats reveal occurrence three evolutionary lineages that have probably originated distinct glacial refugia and meet a contact zone near Alps. Moreover, strong haplotypic segregation (ΦST=0.540) suggests breeding females are philopatric. Contrastingly, low population structure at 15 microsatellite loci (FST=0.022),...

Abstract Because of their role in limiting gene flow, geographical barriers like mountains or seas often coincide with intraspecific genetic discontinuities. Although the Strait Gibraltar represents such a potential barrier for both plants and animals, few studies have been conducted on its impact flow. Here we test this effect bat species ( Myotis myotis ) which is apparently distributed sides strait. Six colonies 20 each were sampled southern Spain northern Morocco along linear transect...

Myotis albescens occurs from Mexico southward to Uruguay and Argentina. The species is known for all South American countries except French Guiana Chile.Based on one specimen recently collected in we fill part of the gap distribution America. Shield with other four congeners, which it can be distinguished by external skull traits. As an aid future identifications, provide a key this assemblage.

The genus Myotis is comprised of about 100 species that are unequally distributed between the Northern (81% species) and Southern hemisphere (19% species). Only eight occur in Ethiopian region, but this only biogeographic region with representatives all four classical subgenera, suggesting a diverse assemblage morphotypes. We used sequences mitochondrial DNA gene (cyt b) to investigate evolution phylogenetic position seven species, compared them broad sampling from World other...

The genus Myotishas undergone significant taxonomic revision since the advent of DNA sequencing techniques. Prior morphological examination indicated as many 4 subgenera correlated with foraging strategies. Recent studies using mitochondrial (mtDNA) sequence data have questioned validity these and that several taxa may require reevaluation to their position within Vespertilionidae. Nevertheless, no study has used large-scale nuclear examine relationships Myotis. We generated 4,656 base pairs...

Adaptive radiations are defined as rapid diversification with phenotypic innovation led by colonization to new environments. Notably, adaptive can occur in parallel when habitats similar selective pressures accessible promoting convergent adaptions. Although evolution appears be a common process, it is unclear what the main drivers leading reappearance of morphologies or ecological roles. We explore this question Myotis bats, only Chiropteran genus worldwide distribution. Three foraging...

Myotis alcathoe is one of the iconic species among cryptic European bats, described only 20 years ago. Despite research efforts, there still limited knowledge about its distribution and ecology, leading to Data Deficient status on IUCN Red List. Ukraine lies eastern border species' range, with a few known records. Here, we document new genetically confirmed record M. from Central-Western part (Rivne Region, in “Dermansko-Ostrozkyi” National Nature Park). Eight individuals were mist-netted...

Abstract Analyses of mitochondrial DNA (mtDNA) control region polymorphism and variation at 10 nuclear microsatellite loci were used to investigate the mechanisms genetic consequences postglacial expansion Myotis myotis in Europe. Initial sampling consisted 480 bats genotyped 24 nursery colonies arranged along a transect ≈ 3000 km. The phylogeographical survey based on mtDNA sequences revealed existence major subdivisions across this area, with several suture zones between haplogroups. Such...

Mitochondrial DNA (mtDNA) variation in the cytochrome b gene was determined for two divergent taxa of pocket gophers, Thomomys bottae actuosus and T. b. ruidosae . These hybridize a narrow contact zone, but introgression nuclear markers such as allozymes or chromosomes does not extend much beyond hybrid zone (Patton et al. 1979). We found that despite their distinctness, subspecies shared very similar mtDNA haplotypes. By comparison phylogenetic histories derived from (allozymes) haplotypes...

Phylogenetic relationships between taxa are not necessarily reflected by morphological data due to widespread homoplasy and convergence. However, combining molecular provides insights into the evolution of biological forms potential factors involved. Here we focus on a complex three bats with unclear taxonomic affinities: Myotis myotis, blythii punicus. Traditional morphometric methods failed separate them, whereas recent molecular-based studies suggested that they constitute species. In...

The distribution of biota from the temperate regions changed considerably during climatic fluctuations Quaternary. This is especially true for many bat species that depend on warm roosts to install their nursery colonies. Surveys genetic variation among European bats have shown southern peninsulas (Iberia and Balkans) harbour endemic diversity, but date, no such surveys been conducted in third potential glacial refuge area, Apennine peninsula. We report here phylogeographical analysis 115...

The Myotis nattereri species complex consists of an entangled group Western Palaearctic bats characterized by fringing hairs along the rear edge their uropatagium. Some members are relatively common while others rare but all forms morphologically very similar and taxonomy is unresolved. Recent studies based on different molecular markers have shown that several major unexpected lineages exist within this forest-dwelling bats. All mitochondrial nuclear tested to date these evolved as fully...
