Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable biodiversity loss
Abstract Freshwater macroinvertebrates are a diverse group and play key ecological roles, including accelerating nutrient cycling, filtering water, controlling primary producers, providing food for predators. Their differences in tolerances short generation times manifest rapid community responses to change. Macroinvertebrate composition is an indicator of water quality. In Europe, efforts improve quality following environmental legislation, primarily starting the 1980s, may have driven...
The assessment of the current state lakes and reservoirs is a prerequisite for conservation management these ecosystems as well their restoration mitigation damages triggered by various pressures. aim present study was to explore associations zooplankton communities with trophic (or) ecological potential (EP) reservoirs, incorporating also standard physical chemical factors primary production. We recorded 48 taxa: 32 rotifer, nine cladoceran seven copepod taxa. Our results suggested...
A survey of the macrozoobenthos communities in Maritsa River (South Bulgaria) was carried out summer 2021. Benthic samples were collected and physicochemical parameters (water temperature, pH, conductivity, dissolved oxygen nutrients) measured at 15 sites located on main river its tributary system. The studied belonged to different types characterised diversity ecological conditions—from unaffected anthropogenically influenced stretches. In addition, data from a study conducted 2020 used...
The importance of adequate biological assessments rivers based on aquatic assemblages is essential to establish recovery measures. Macrophyte and macroinvertebrate communities react differently in time response strength diverse stressors. Our hypothesis was that each group a result specific combined abiotic factors stressor’s impact. To address the above, both quality elements (BQEs) values ecological ratio (EQR) were studied relation four parameters five physico-chemical Discrepancies more...
Two decades after the first record of invasive mussel Corbicula fluminea (Müller, 1774) in Bulgaria 2001, it has been found many surface lotic and standing waters Bulgarian Danube River Basin.
 The aim current study is to report finding C. environment East Aegean water basin Bulgaria. Six new localities mussel, all situated lower stretches Tundzha (two) Maritsa (four) were registered. distributional patterns abundance its populations relation environmental conditions analyzed. adaptive...
