The Biodiversity of Aquatic Gastropods in the Steppe Zone the West Siberian Plain (Western Siberia, Russia)
Journal Title: Open Access Journal of Environmental and Soil Sciences - Year 2019, Vol 2, Issue 1
Abstract
This study describes the species diversity, abundance and biomass of gastropods in the ecosystems of the southern part of Western Siberia (Karasukskii district, Novosibirsk Oblast). Distribution and Quantitative Characteristics of Common Species of Gastropoda are calculated. Twenty-one species of snails belonging to seven families were recorded, Lymnaeidae, Planorbidae, Bulinidae, Physidae, Bithynhdae, Succineidae, and Zonitidae. The biodiversity of mollusks was studied using the Shannon- Weaver index. The ecology of pond snails has been studied in the waterbodies of the central part of European Russia [1], but the authors emphasize the necessity of conducting similar studies in Siberia, and in other regions of our country. Gastropoda are widely distributed in the water bodies of the southern part of Western Siberia. They are an important component of benthic communities and take part in a number of trophic relationships. Some information about the ecology of freshwater snails’ species is presented in the publications [2-4] but many aspects are still poorly studied. In particular, quantitative data on the communities of mollusks are scanty [5,6]. We, in a previous work [7] Jacquard index biodiversity gastropods are calculated. The aim of the present investigation was to identify the occurrence and distribution of freshwater snails in the lake, rivers systems from the steppe zone the West Siberian Plain. The species composition and biomass of snails in August of 2009 were studied (Novosibirsk Oblast, south of Western Siberia). Samples were collected in different parts in the Karasuk River in the upstream(near the villages of Bystrukha N 54026’ 53,2’’; E 800 55’ 50,5’ and Chernovka N 540 09’ 53,2’’; E. 800 02’ 54,2’) and downstream near the villages of Gramotino and Sorochikha (N 500 45’ 19,4’’; E. 780 20’ 15,1’ and N 530 43’ 19,7’’; E 770 56’ 29,5’), and in six lakes of the Karasuk system: Astrodym N 53036’ 59,4’’; E 770 48’ 04,7’, Krivoye (reaches: Blagodatnoye N 530 49’ 59,3’’; E. 780 03’ 17,3’’, Sopatoye N 530 48’ 28,7’’; E 78002’ 18,5’’ and Gusinoye N 530 48’ 13,0’’; E 78004’ 00,8’’), Krotovo N 530 43’ 30’’; E 770 51’ 31’’, Kusgan N 53044’ 23’’; E 770 53’25’’, Melkoye N 530 47’ 37,9’’; E 780 16’34,91’’, Titovo N 530 45’ 25,8’’; E 770 56’13,2’’.
