A selective sweep is the result of strong positive selection driving newly occurring or standing genetic variants to fixation, and can dramatically alter pattern distribution allelic diversity in a population. Population-level sequencing data have enabled discoveries sweeps associated with genes involved recent adaptations many species. In contrast, much debate but little evidence addresses whether “selfish” are capable fixation—thereby leaving signatures identical classical sweeps—despite...
Abstract Mus cypriacus is one of three small palaeoendemic mammals that have survived the Mediterranean islands’ anthropization. This species, endemic to Cyprus, was described in 2006 and stands out as last mammal species been discovered Europe. Despite scarce data on its genetics, ecology, life-history traits, assessed Least Concern LC IUCN Red List, partly due morphological similarity with sympatric house mouse prevented earlier identification. Our study uses mitochondrial microsatellite...
Abstract Aim The distribution of the western house mouse ( Mus musculus domesticus ) around world has been strongly influenced by movement humans. close association between and human phylogeography primarily studied in peripheral species. Here, we inferred complex colonization history Cyprus, situated to centre one first European islands be colonized We investigated resulting complexity population genetics as well considering value a bioproxy for studying modern movement. Location study was...
Several karyotypic forms have been previously described in populations of the vole species <i>Microtus thomasi</i> from Greece. In particular, karyomorphs ‘thomasi’ and ‘atticus’ differ X chromosome morphology, being acrocentric subtelocentric, respectively. Furthermore, remarkable heterochromatin content variability has sex chromosomes both karyomorphs. Genomic DNA digestion with <i>Alu</i>I allowed us to clone an 884 bp long repeated sequence (Mth-Alu900) karyomorph...
The underground vole Microtus thomasi, a Balkan endemic, displays remarkable variability in sex chromosome size and morphology. In the present study, we demonstrate this two of its chromosomal races with 2n = 44 (i.e. 'thomasi' 'atticus') use C-banding on sample 189 individuals from 50 localities Greece. 'thomasi', five different, acrocentric X variants (X0–X4) are described, which differ significantly size, due to heterochromatin addition. Also, three Y described (Y0–Y2), ranging very small...

The karyotype of the Cretan spiny mouse Acomys minous was examined with chromosome banding techniques in 53 individuals from 12 localities Crete, aiming to gain a more detailed knowledge on chromosomal constitution and variability its natural populations. We found that it consists three Robertsonian (Rb) populations 2n = 38, 40 42, respectively, last one being reported for first time, stable fundamental number (FNa 66, FN 68). G-banding pattern proves Rb are closely linked phylogenetically...
The karyotype of the house mouse, Mus musculus domesticus, was examined in 282 specimens from 44 localities, an effort to gain better understanding Robertsonian (Rb) variation known exist Greece. We consider that Rb system exists Peloponnisos, southern Greece, distributed area is substantially larger than previously known. It consists at least three races with 2n = 30, 24 and 28, respectively, last being reported for first time this paper carrying Rb(3.6), Rb(8.12), Rb(10.14), Rb(13.15),...
Abstract Spiny mice of the Acomys cahirinus group display a complex geographical structure in Eastern Mediterranean area, as shown by previous genetic and chromosomal studies. To better elucidate evolutionary relationships between insular populations from Crete Cyprus continental North Africa Cilicia Turkey, morphometric variations were investigated, based on mitochondrial D-loop sequences, size shape first upper molar. The Cypriot Cilician show idiosyncratic divergence molar shape, while...
Abstract The natural populations of the house mouse, Mus musculus domesticus, Euro-Mediterranean region have been under extensive scrutiny for several years, thanks to an Robertsonian chromosomal variation. However, this subspecies is also known occasional appearance Homogenously Staining Regions (HSRs) in chromosome 1 karyotype. Based on C-banding study 236 mice from 32 localities Peloponnisos, S Greece, eight Rb individuals two were found with HSRs their karyotype (HSR incidence: 3.4%),...

We found that density of proliferating neural stem/ progenitor cells (NSPCs) neuroblasts was significantly lower Subependymal Zone stem cell niche lab mice when compared with pine voles captured wild, seasonal variation observed only voles. Moreover, levels proliferation were decrease proportion numbers chromosomes (from typical 2n = 40 down 26)...
Abstract The little owl ( Athene noctua ) is a common raptor in Mediterranean habitats. To acquire more information on its diet, this study identified cranial and post-cranial skeletal material from 70 pellets collected during the 2016 2017 breeding seasons. was used to quantify owl’s relative prey abundance using MNI (minimum number of individuals), taphonomical unit. This first examine diet Peloponnese (southern Greece). After examining 3,691 isolated exoskeletal remains processed pellets,...
