MOLLUSK OF THE FAMILY BITHYNIIDAE (GASTROPODA, LITTORINIMORPHA) OF THE LOWER VOLGA PLAINS RIVER
Background. Preservation of stable and sustainable natural conditions in aquatic ecosystems of various territories is the most urgent problem of nature management in many regions of the world. Occurring changes together with the anthropogenic factor intensify the processes of destabilization of watercourse biocenoses.

NUTRITIONAL BUDGET FOR THE FRESHWATER SNAIL BITHYNIA GRAECA (GASTROPODA: BITHYNIIDAE) [PDF]
The nutritional budget of Buhynia graeca (Westerlund) was studied using samples of a snail population of Lake Kerkini (N Greece). A laboratory investigation of food consumption and assimilation in B. graeca was undertaken using Aufwuchs as food. On the basis of this investigation estimates of natural consumption and assimilation efficiencies were made.

Rivers are impacted ecosystems that need to be monitored regularly. Here, we have tested a metabarcoding approach to compare the results on water quality monitoring with conventional assessments for benthic macroinvertebrates. Water quality monitoring in freshwaters using macroinvertebrate eDNA performs equally well than conventional morphological ...

Abstract Type and intensity of land‐use vary in space and time and strongly contribute to changes in richness and composition of species communities. In this study, we examined land snail communities in forests and grasslands in three regions of Germany.

Examination of bithyniid snails as an assessment method of natural foci of prosthogonimosis
The purpose of the research is to compare two methods for assessing natural foci of prosthogonimosis based on defi nitive and/or fi rst intermediate hosts infected with trematodes of the family Prosthоgonimidae (Lühe, 1909).Materials and methods.

Background and Objectives. Lymnaeid snails are the known intermediate hosts of the liver fluke Fasciola spp. and therefore play an important role in the parasite’s life cycle. The study is conducted to determine specificity of snail host‐parasite interaction and to determine the snail‐trematode infection rate by cercarial emergence, characterizing the ...

ABSTRACT Aim The role of historical drainage connectivity and the influence of water level fluctuations in African lakes on the evolution and distribution of macroinvertebrates remain poorly understood. This is partly because evolutionary biology research has largely focused on mobile vertebrates, such as cichlids.
