Summary Pleistocene glaciations affected the present‐day distribution and genetic diversity of animal species in Europe. Deep subdivisions observed European populations widespread freshwater isopod morphospecies, Asellus aquaticus , suggest presence putative cryptic species. We used DNA barcodes cytochrome c oxidase subunit 1 ( COI ) gene combined with distance‐ tree‐based methods delimitation as a rapid tool for assessing number distinct operational taxonomic units OTU s) representing...
Tentatively dated, the Plio-/Pleistocene origin of ancient Lake Ohrid on Balkan Peninsula makes it oldest lake in Europe. Given surface area and adjusted endemicity rate, may be also defined as most diverse all lakes world. From animal groups endemic to this lake, gammarids are amongst scarcely known terms their diversity phylogenetic relationships. Partial DNA sequences two mitochondrial genes, cytochrome oxidase subunit I (cox1) 16S ribosomal RNA (16S rRNA) eight Gammarus species from...
Quantifying patterns of genetic diversity and differentiation among populations Arctic birds is fundamental for understanding past ongoing population processes in the Arctic. However, many important species remains uninvestigated. Here, phylogeography genetics were examined worldwide a small seabird, little auk (dovekie, Alle alle)—the most numerous avian ecosystem. Blood samples or feathers collected from 328 auks (325 nominate subspecies 3 A. a. polaris) nine main breeding aggregations...
Bacterial endosymbionts of aquatic invertebrates remain poorly studied. This is at least partly due to a lack suitable techniques and primers for their identification. We designed pair non-degenerate which enabled us amplify fragment ca. 500 bp the 16S rRNA gene from various known bacterial endosymbiont species. By using this approach, we identified four endosymbionts, two endoparasites one uncultured bacterium in seven, taxonomically diverse, freshwater crustacean hosts temporary waters...
Erpobdella borisi n. sp. is a predatory leech inhabiting cave waters in Iran. Probably, it either troglobiont or troglophile. The has no eyes, and the complete mid-body somite divided unequally into five annuli. Results of phylogenetic analysis based on morphological characters COI gene sequence indicate species to be closely related japonica, E. octoculata testacea.
Identifying natural populations that might be considered separate units using morphology, genotype or both is important in understanding the process of speciation and for conservation. We examined relationships between only two subspecies most numerous Arctic seabird, Little Auk Alle alle , morphological (wing head‐bill lengths) genetic data (482 base pairs mitochondrial control region seven nuclear microsatellite loci). found significant differences subspecies, A. a. polaris being...
Mussels of the family Unionidae are important components freshwater ecosystems. Alarmingly, International Union for Conservation Nature and Natural Resources Red List Threatened Species identifies almost 200 unionid species as extinct, endangered, or threatened. Their decline is result human impact on habitats, decrease host fish populations. The Thick Shelled River Mussel Unio crassus Philipsson, 1788 one examples that has been reported to show a dramatic Hierarchical organization riverine...
Abstract Ancient lakes as places of extensive speciation processes have been characterized by a high degree endemicity and biodiversity. The most outstanding European ancient lake is the oligotrophic karstic Balkan Lake Ohrid. inhabited number endemic species, but their evolutionary history largely unresolved. in present study, genetic structure, gene genealogy demographic representatives Ohridian Proasellus species were studied using both biparentally (allozyme loci) maternally (partial...
Abstract The subfamily Candoninae Kaufmann, 1900a is one of the most taxonomically difficult and species-rich lineages non-marine Ostracoda. It widely distributed, inhabiting all kinds surface subterranean waters, but its taxonomy remains unclear generic relationships ambiguous due to a number homoplasies. To verify morphology-based monophyly European morphogenera we propose analysis mitochondrial fragment encoding cytochrome c oxidase subunit I (COI). We investigated 75 individuals 25...
Abstract The majority of Polish studies on freshwater cyclopoids focused surface water fauna. There are relatively few data copepods subterranean waters. Thus, in our research, were collected from 37 different, mostly groundwater-dependent habitats (i.e. caves, springs, wells, interstitial and overhead environments) over a period five years between 2005 2010. A total 22 species belonging to eight genera found. Some species, previously not recorded or known only sites Poland, proved be...
This is the first study of morphological and molecular variation in two peripheral populations butterfly Jutta Arctic, Oeneis jutta, a glacial relict species endangered by fragmentation its habitat Poland.An analysis characteristics indicates that both Polish are similar but differ significantly some characteristics.Levels genetic were assessed using mitochondrial cytochrome oxidase subunit I (COI) NADH dehydrogenase 5 (ND5) gene fragments together with segment mtDNA control region (CR)...
The discovery of genetic (mostly also cryptic) species in the animal world has known an exponential increase since molecular techniques became available. Also, non-marine ostracods (small, bivalved crustaceans with excellent fossil record), many morphospecies have been shown to comprise several species, one them even as much 40 cryptic from Europe and North Africa. Here, we screen 13 populations Central circum-Mediterranean region halophilic continental ostracod Heterocypris salina DNA...
