В статье приведены видовой состав и места находок рукокрылых, сделанных на территории Республики Мор-довия с первой половины XX в. и по настоящее время. Даются краткие оценки встречаемости, относительно-го обилия и характера распространения видов, на основе которых приводятся рекомендации по включению их в Красную книгу региона. В Мордовии отмечено 12 видов летучих мышей. Распространённые и многочис-ленные виды: Pipistrellus nathusii, Myotis daubentonii, M. dasycneme, Nyctalus noctula и Vespertilio murinus. Ши-роко распространённые (обычные), но немногочисленные виды: M. brandtii и Plecotus auritus. Редкие виды: M. nattereri, N. lasiopterus, N. leisleri, P. pygmaeus и P. kuhlii.
Alburnoides holciki was described from the Hari River basin, which was the only basin it was known from. Populations from the Amu Darya basin were previously recognized as A. eichwaldii or Alburnoides sp. Our study recognized specimens of Alburnoides from the Amu Darya basin as A. holciki based on morphological data and the COI barcode gene. The population from the Zeravshan basin showed some morphological differences compared to others but were similar in the COI gene and needs further investigation. New results extend the range of A. holciki for almost 1000 km from the Hari River to the upper Amu Darya tributaries in Tajikistan. The intraspecific genetic similarity in the COI gene between populations in the Hari and Amu Darya rivers supports the geographical hypothesis of a recent connection of these rivers.
Spirlins of the genus Alburnoides are widespread fishes, which taxonomy has been rapidly developing in recent years. Mitochondrial cytochrome c oxidase subunit I (COI) was used as DNA barcode marker to create a reference dataset of Caucasian Alburnoides and to test its barcoding efficiency. All four previously known Caucasian species of Alburnoides were confirmed as valid species with high genetic distances to sister species as well confirmed as Caucasian endemics. Alburnoides samiii, previously known from Sefidroud basin (Iran), was discovered in Transcaucasia. The accuracy of species identification of Ponto-Caspian Alburnoides by DNA barcodes was 100%. In addition, one potentially new species within A. gmelini was revealed. Despite the limited ability of COI to infer phylogenetic relationships, study provided evidence that Ponto-Caspian lineage of Alburnoides includes significantly larger number of species from Caspian Sea basin and inland basins of Central Asia.
The results of an 11-year study of the ichthyofauna in the Moksha River (central part of European Russia) are described here. Thirty-seven species were recorded, including 34 present in rivers and 26 in lake systems. Relative abundance and the occurrence of fish species from different types of water bodies are provided and the diversity of the ichthyofauna for this region is discussed.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
