Amniote vertebrates possess various mechanisms of sex determination, but their variability is not equally distributed. The large evolutionary stability chromosomes in viviparous mammals and birds was believed to be connected with endothermy. However, some ectotherm lineages seem comparably conserved previously there a lack molecular evidence confirm this. Here, we document advanced snakes based on the testing Z-specificity genes using quantitative PCR (qPCR) across 37 snake species (our qPCR...
Sex chromosomes are believed to be stable in endotherms, but young and evolutionary unstable most ectothermic vertebrates. Within lacertids, the widely radiated lizard group, sex have been reported vary morphology heterochromatinization, which may suggest turnovers during evolution of group. We compared partial gene content Z-specific part across major lineages lacertids discovered a strong stability chromosomes. can conclude that common ancestor living around 70 million years ago (Mya),...
Host specificity in parasites represents the extent to which a parasite's distribution is limited certain host species. Considering host-specific of primarily freshwater fish (such as gill monogeneans), their biogeographical essentially influenced by both evolutionary and ecological processes. Due capacity for historical dispersion fish, specific coevolving may, through host-parasite associations, at least partially reveal routes (or contacts) We used Dactylogyrus spp., cyprinid infer...
Hybridization and incomplete lineage sorting are common confounding factors in phylogeny speciation resulting mitonuclear disparity. Mitochondrial introgression, a particular case of hybridization, may, extreme cases, lead to replacement the mitochondrial genome one species with that another (mitochondrial capture). We investigated introgression involving two cyprinid genus Squalius western Peloponnese region Greece using molecular morphological data. found evidence complete keadicus into...
In order to better understand the complex geologic history of Mediterranean area, we have analysed evolutionary history, phylogeographic structure and molecular diversity freshwater fishes belonging genus Telestes. As primary distributed largely in basin, this represents a suitable model system for investigating historical biogeography drainage systems southern Europe. investigation included samples representing all Telestes species based our analyses on one mitochondrial nuclear gene. We...
Parasites exhibiting a high degree of host specificity are expected to be intimately associated with their hosts. Therefore, the evolution host-specific parasites is at least partially shaped by evolutionary history and distribution such Gill ectoparasites Dactylogyrus (Monogenea) specific cyprinid fish. In present study, we investigated 47 species from Balkan Peninsula, Mediteranean region highest diversity in Europe, central European cyprinids. Phylogenetic analyses revealed four...
Abstract Amniotes possess variability in sex determination, from environmental determination (ESD), where no chromosomes are present, to genotypic (GSD) with highly differentiated chromosomes. Some evolutionary scenarios postulate high stability of and rare transitions GSD ESD. However, chromosome turnovers two independent ZZ/ZW ESD were previously reported the lacertid lizards. Here, we examined homology wide phylogenetic spectrum lacertids their outgroups by comparing gene copy numbers...
Diplozoidae are common monogenean ectoparasites of cyprinoid fish, with the genus Paradiplozoon being most diversified. Despite recent studies on from Europe, Africa and Asia, diversity, distribution phylogeny this parasite group appears to be still underestimated in Middle East. The objective study was investigate endemism host specificity diplozoids parasitizing fish East, considering region as an important historical interchange fauna, elucidate phylogenetic position Eastern species...
Abstract The distribution of the neutral component genetic diversity is interplay historical and ongoing processes resulting in species‐specific structure populations, which can, however, be disrupted by interspecific hybridisation introgression. In this study, we focused on two species water frogs, Pelophylax epeiroticus P. kurtmuelleri , live sympatry southwestern Balkans, to investigate rate population using cytogenetic, mitochondrial (ND2) nuclear DNA (microsatellite) markers. overall...
Abstract: Interspecific gene flow may profoundly impact genome integrity and adaptive evolution in hybridizing species, leading to novelties such as transgressive traits, supergenes, or, sometimes, the emergence of asexually reproducing lineages. Conventionally, introgression is thought proceed between reproductively interacting mediated by recombining interspecific hybrids, while asexual lineages are considered evolutionary deadlock for genomes trapped them. Our study on Cobitis loaches...
The region of Balkans is often considered as an ichthyologic "hot spot", with a great number species and high portion endemics living in fresh waters relatively small area. Adriatic watershed Croatia Herzegovina inhabited by six spined loach (genus Cobitis) whose extinction risk estimations were based solely on their extent occurrence (and/or area occupancy) its fragmentation, conservation proposals do not consider diversity below level. In this investigation we employed molecular genetic...
Facultative parthenogenesis in vertebrates is believed to be exceptional, and wherever documented, it always led single-sex progeny with genome-wide homozygosity. We report the first challenge this paradigm: frequent facultative previously assumed sexually reproducing tropical night lizard Lepidophyma smithii results offspring of both sexes preserves heterozygosity many loci polymorphic their mothers. Moreover, we documented a mixture parthenogenetically produced single clutch, which...
The study of host–parasite coevolution is one the cornerstones evolutionary biology. majority fish ectoparasites belonging to genus Dactylogyrus (Monogenea) exhibit a high degree host specificity. Therefore, it expected that their history primarily linked with cyprinoid hosts and historical formation landmasses. In present study, we used cophylogenetic approach investigate coevolutionary relationships between endemic Cyprinoidea (Cyprinidae Leuciscidae) from selected regions in southern...
The genus Pelophylax (water frogs) includes relatively common, widely distributed, and even invasive species, but also endemic taxa with small ranges limited knowledge concerning their ecology evolution. Among poorly studied species belong endemics of the southwestern Balkans, namely shqipericus , P. epeiroticus kurtmuelleri . In this study, we focused on genetic variability these aiming to reveal phylogeographic patterns Quaternary history. We used 1,088 published newly obtained sequences...
The suborder Gobioidei is among the most diverse groups of vertebrates, comprising about 2310 species. In fossil record gobioids date back to early Eocene (c. 50 m.y. ago), and a considerable increase in numbers described species evident since middle Miocene 16 ago). About 40 skeleton-based gobioid > 100 otolith-based have been until date. However, assignment specific families has often remained tentative, even if well preserved complete specimens are available. reasons that...
Abstract The epicontinental fauna of the Iberian Peninsula is strongly influenced by its geographical history. As possibilities for dispersion organisms into and from this region were (and still are) limited, local consists almost exclusively endemic species. Almost all freshwater fishes families Leuciscidae Cyprinidae are on-going research on these taxa continually uncovers new Nevertheless, information their host-specific parasites remains scarce. In study, we investigate diversity...
The morphometric, meristic and phenotypical characters of the members genus Alburnus from Adriatic Basin were analyzed on specimens 11 localities, representing eight watersheds. number gill rakers, lateral line scales, branched anal fin rays coverage ventral keel by scales have greatest significance in differentiating between species. Significant morphological differences exist population Lake Lugano (type locality for Alborella maxima Fatio, 1882) all remaining investigated populations....
Gobiidae (Gobiiformes, Teleostei) is among the largest families of vertebrates. These fishes are distributed worldwide and contribute significantly to species diversity in marine habitats reefs. However, their fossil record sparse prior Miocene little known about course diversification clade. Here we report exceptionally well-preserved skeletal remains oldest Gobius from an Early (Burdigalian) ecosystem Central Europe (Czech Republic). jarosi Přikryl & Reichenbacher sp. nov. dated 19.1–20.4...
