Freshwater pearl mussels (FPMs, Margaritifera margaritifera, Linnaeus, 1758) are endangered and particularly vulnerable to climate change. To create effective conservation strategies, we studied their thermal tolerance the impact of elevated water temperatures on growth survival. Our experiments included field mesocosm studies in five FPM-streams Vogtland region (Germany) (2016 2020), as well laboratory at ranging from 1 26 °C. Growth juvenile FPMs increased significantly within a...
Abstract The freshwater pearl mussel Margaritifera margaritifera is an endangered bivalve which usually regarded as sedentary, although individual movement has been observed both vertically and horizontally. Little known about the causes rates of movement. objective this study was to test effect microhabitat characteristics on horizontal distance mussels. A total 120 mussels (length range 40–59 mm) were marked individually with passive integrated transponder tags, placed in stream...
Abstract The freshwater pearl mussel (FPM) is among the most endangered species worldwide. few remaining populations suffer from low recruitment rates and are subject to habitat fragmentation, pollution, siltation, decline or loss of host fish populations, climate change. Successful conservation strategies for FPM require a holistic understanding its ecological requirements, life history, population dynamics, prerequisites. Although requirements well described, food at different stages have...
Abstract Detritus is an important energy source of stream food webs. Being a mix allochthonous and autochthonous sources, it often unknown, which components contribute to the growth organisms. This study focussed on comparison two different detritus types (riparian detritus) with respect quality effects as fitness parameter juvenile freshwater pearl mussels (FPM). We performed feeding experiments FPM under laboratory conditions using from four natural sources each. Food was determined by...
A significant part of freshwater mussel populations has strongly declined and many species are severely threatened nowadays. Captive breeding programs often form a central conservation strategies. As the life cycles include an obligate parasitic phase, host fish health is crucial component successful efforts. However, information about safe application therapeutants in captive scarce. This article summarizes practical experiences Europe. In total, eight different were used to treat...
