Freshwater mussels (Order Unionida) are highly threatened. Interspecific competition for food sources with invasive alien species is considered to be one of the factors responsible their decline because successful invaders expected have wider trophic niches and more flexible feeding strategies than native counterparts. In this study, carbon (?13C: 13C/12C) nitrogen (?15N: 15N/14N) stable isotop...

Though Ukraine is one of the countries with insufficient water supply, northern region central Polissia has a dense river network. The region’s major rivers – Teteriv, Sluch, Ubort, and Uzh have undergone significant anthropogenic change. Water pollution adversely affected their fauna, including Unionidae (Mollusca: Bivalvia). This study monitored these changes, was conducted in two stages. A t...

Predatory, non-native fauna can influence biodiversity and trophic dynamics in invaded ecosystems. Signal crayfish (Pacifastacus leniusculus) are a highly successful invader, which have altered freshwater benthic communities, including bivalve populations. Bivalves keystone group global decline, partly due to invasion by alien species. However, little is known about the predatory impacts of inv...

The aim of this study was to assess the extent which behavioural traits freshwater mussels provide suitable indicators stress in individuals, towards advancement non-invasive, remote monitoring techniques examine population condition. Variation expression particular metrics examined accordance with measurements oxygen consumption, across environmental stressors (aerial exposure and high concent...

crude oil is enriched in polycyclic aromatic hydrocarbons (pahs). many pah analogs have proved to potentially damage dna. dna damage can be assessed using various biomarkers to find out the degree of genotoxicity of pollutants following in vitro exposure. in this research the comet assay and micronucleus (mn) test were used to detect dna damages and cytogenetic changes following crude oil expos...
