Europe has a long history of human pressure on freshwater ecosystems. As continues to grow and new threats emerge, there is an urgent need for conservation biodiversity its ecosystem services. However, whilst some taxonomic groups, mainly vertebrates, have received disproportionate amount attention funds, other groups remain largely off the public scientific radar. Freshwater mussels (Bivalvia, Unionida) are alarming example this bias here we point out six conceptual areas that immediate...
Abstract Climate change may lead to range shifts, and barriers such displacements result in extirpations from previously suitable habitats. This be particularly important freshwater ecosystems that are highly fragmented by anthropogenic obstacles, as dams other smaller in‐stream barriers. Conservation planning freshwaters should consider the dynamic effects of climate ability species cope with it. In this study, we developed a framework for incorporating climate‐driven dispersal into...
Abstract The freshwater pearl mussel Margaritifera margaritifera has been suffering major population declines in Europe. This endangered species is a host specialist and exclusively requires salmonid ( Salmo trutta salar ) to complete its life cycle. In theory, obligatory biotic interactions should deserve special conservation attention, because the loss or massive decline of fish hosts may elicit extirpation their affiliated species. While many threats disturbing M. are similarly affecting...
Abstract Aim Freshwater mussels are among the most threatened taxa in world, partially due to dependence on fish hosts complete their life cycle. Knowledge about role of environmental and biotic drivers determining mussels' distribution is currently lacking. We aimed assess test if co‐occurrence patterns were able identify mussel‐host interactions. Location Douro River basin (Iberian Peninsula). Taxon Four freshwater ten hosts. Methods Joint species models (JSDMs) fitted presence‐absence...
Background. Freshwater fishes are among the most threatened taxa worldwide. The proliferation of introduced species in Iberian Peninsula is currently one main drivers native fish declines. One such species, bleak, Alburnus alburnus (Linnaeus, 1758), has become widespread last 25 years and, due to its phylogenetic proximity, poses a high risk hybridization with species. aim this study was improve current knowledge on issue by 1) evaluating presence hybrids wild, using molecular screening...
Freshwater salinization is a world-wide phenomenon threatening stream communities and ecosystem functioning. In these systems, litter decomposition main ecosystem-level process where fungi (aquatic hyphomycetes) play central role linking basal resource higher levels of food-web. The current study evaluated the impact aquatic hyphomycete richness on leaf when subjected to salinization. microcosm study, we analysed mass loss, fungal biomass, respiration sporulation rate by assemblages at three...
The Iberian Peninsula has been subjected to numerous fish introductions and the colonization of new areas by non-native species is constantly reported. However, there a lack knowledge about many aspects bio-ecology these their invasive success within environmental context Mediterranean temporary rivers. This study aimed address following questions: (i) what are main regional local drivers influencing assemblages differentiating native from species, particularly A. alburnus?; (ii)...
Behavioural interactions between the endangered native fish Saramugo, Anaecypris hispanica, and invasive Bleak, Alburnus alburnusInvasive species have potential to impact through interference competition, which is especially concerning for conservation of valuable endemic ichtyofauna Iberian Peninsula.This study investigated negative effect bleak alburnus on behaviour critically saramugo hispanica.The patterns were analysed under experimental conditions in outdoor tanks observations shelter...
Many river networks in southern Europe are intermittent. In summer, the surface flow is zero and many streams become isolated pools. this study, 128 dry season pools were studied covering first- to fourth-order on Degebe River network (south Portugal). The aim of study was identify pool types based environmental drivers conditions fish assemblages. streambed area exceeded 50% all reaches 95% headwater sections. features primarily shaped by their location network, which determined morphology...
