“…lakes Ohrid, Megáli Préspa, Mikri Préspa, Skadar) have the largest number of endemic freshwater taxa from the Mediterranean region and have long been recognised as centres of biodiversity (Hauffe et al 2011;Wagner and Wilke 2011). For all these considerations, it seems relevant to consider superimposed synergistic interactions between current and past environmental factors on freshwater species distribution, together with historical extinction processes, not yet documented, due to human pressure (Ricciardi and Rasmussen 1999;Regnier et al 2009;Vaughn 2012).…”

We analysed changes in species richness and endemics of freshwater gastropods along the Western Palearctic, within the following boundaries: 10°W-30°E, 32°N-71°N. The aims of this study were to test: (1) the consistency of latitudinal distribution of Western Palearctic freshwater gastropods; and (2) the relationships between freshwater gastropods and environmental factors. Analyses were based on presence/absence data of 911 freshwater gastropod species in 474 sites, located along three bioclimas (boreal, Mediterranean and temperate) and four Köp-pen-Geiger climatic regions (arid, cold, polar and alpine, and temperate). Five environmental variables were used to assess their influence on the distribution of freshwater gastropods. Relationships between variables were studied using parametric, non-parametric and multivariate statistics, and general regression models. Species number per degree of latitude followed a hump-shaped curve, increasing to 41°N-43°N and, from there, decreasing to reach minimum values in boreal areas. Relationships between species richness and endemics with current and past environmental variables were likewise discussed.

“…Freshwater Bivalvia are threatened, and their populations are declining at a global scale, and among them freshwater mussels (Bivalvia: Unionacea) are one of the most endangered groups in the world (Bogan 2008, Vaughn 2012. This phenomenon has been best documented for rivers (aLdrIdge 2000, grabow et al 2000, cosgrove & hastIe 2001, weber 2005, gangLoff & FemIneLLa 2007, mouthon & daufresne 2008, sousa et al 2008.…”

Anthropogenically elevated nutrient concentration occurs in both ground and surface waters and cause grave environmental problems which are responsible for the degradation of water quality on a worldwide scale. The progressive anthropogenic pressure caused by prolonged agricultural activity has a negative effect on most water ecosystems including rivers and reservoirs. Freshwater molluscs, which are hololimnic organisms, have a limited mobility; therefore, they are good bioindicators of changes in their habitats. They reflect the abiotic or biotic state of water habitats, which represents the impact of environmental change on the habitat, community as well as on the ecosystem. A long-term survey of mollusc communities revealed the occurrence of 44 species including some rare, vulnerable, threatened or legally protected species, e.g. Borysthenia naticina, Unio crassus, Anodonta cygnea, Pseudanodonta complanata or Sphaerium rivicola, in the Wkra River, its tributaries and selected oxbow lakes. In the Wkra River catchment area, the mollusc communities, including U. crassus (Habitats Directive Natura 2000), are under a combined effect of several environmental factors. Conductivity, hardness, current velocity, river width, temperature, nutrient concentration and the size of sediment particles were the parameters most associated (statistically significant according to the forward selection results) with the distribution of mollusc species. The forward selection results showed that the concentration of dissolved oxygen and the occurrence of macrophytes also exerted a significant influence on the distribution of Mollusca. Among environmental factors, anthropogenically elevated concentrations of nitrites and nitrates in the water were the most predictive parameters that negatively influenced (stressors) the structure of mollusc communities. The novel findings of this survey showed that some mollusc species could tolerate wider ranges of some environmental factors and higher concentrations of nutrients than had been expected. U. crassus is more tolerant of a relatively high concentration of nitrates in the water than was previously expected, as well as of nitrites and phosphates, and it can survive in rivers with relatively high nutrient concentration. The present results confirm both the field and the toxicological research on the negative effect of nitrites and nitrates, which is caused by their toxicity to freshwater molluscs. The number of individuals, number of mollusc species and density decreased dramatically within the last year of the survey in the Wkra River and its tributaries. This phenomenon seems to be a direct result of the nutrient enrichment in the Wkra River catchment area, the regulation of riverbeds or an indirect result, e.g. lack of primary or appropriate host fishes for unionid species. The declining trend in the global mollusc population has probably begun to occur in the Wkra River catchment area.

“…The influence of stream flows on mussels is pervasive, making them a model study system to investigate the environmental effects of hydrological alterations. Mussels rely on predictable stream flows for reproduction (Galbraith and Vaughn 2011), the maintenance of tolerable temperatures (Gagnon et al 2004;Spooner and Vaughn 2008;Gough et al 2012) and stable habitats (Allen and Vaughn 2010), as well as the abundance of host fish required for juvenile mussel recruitment (Roy et al 2005;Vaughn 2012). Changes in hydrology due to dam construction and river channelization is considered to be the primary cause of mussel declines in the US (Vaughn and Taylor 1999;Strayer et al 2004), and effects of climate change and water withdrawals are predicted to accelerate mussel declines in the future (Spooner et al 2011).…”

Droughts often pose situations where stream water levels are lowest while human demand for water is highest. Here we present results of an observational study documenting changes in freshwater mussel communities in two southern US rivers during a multi-year drought. During a 13-year period water releases into the Kiamichi River from an impoundment were halted during droughts, while minimum releases from an impoundment were maintained in the Little River. The Kiamichi observed nearly twice as many low-flow events known to cause mussel mortality than the Little, and regression tree analyses suggest that this difference was influenced by reduced releases. During this period mussel communities in the Kiamichi declined in species richness and abundance, changes that were not observed in the Little. These results suggest that reduced releases during droughts likely led to mussel declines in one river, while maintaining reservoir releases may have sustained mussel populations in another.
