ABSTRACT
BACKGROUND: This publication describes a dataset containing information on 1328 occurrences of fishes in the Kuban River Basin, the longest river of Northern Caucasus and representing its own freshwater ecoregion (428 Kuban Ecoregion). All observations have precise geo-referencing with the names of water bodies (rivers, lakes etc.). The dataset is based on both literature data (509 occurrences) and our own sampling (814 occurrences). Observations were carried out between 1889 and 2020. NEW INFORMATION: The majority (> 61%) of occurrences in the presented data are published for the first time. This extended dataset contributes significantly to fish fauna survey in the Kuban River ecoregion.
ABSTRACT
A catalog of aquatic and semiaquatic Heteroptera of the northwest Caucasus is provided based on literature reports and field collections. Representatives of 50 species of the infraorders Nepomorpha and Gerromorpha are listed and are distributed in 11 families, including Aphelocheiridae (1 genus, 1 species), Corixidae (6 genera, 23 species), Gerridae (3 genera, 9 species), Hebridae (1 genus, 2 species), Hydrometridae (1 genus, 2 species), Mesoveliidae (1 genus, 1 species), Naucoridae (1 genus, 1 species), Nepidae (2 genera, 3 species), Notonectidae (2 genera, 4 species), Pleidae (1 genus, 1 species) and Veliidae (2 genera, 3 species). Five species listed for the fauna of the northwest Caucasus are doubtful. Types of ranges of all species are given. Zoogeography of the regional fauna is discussed.
