The effects of endangered freshwater pearl mussels on channel morphology and flow in a low-gradient sandy river

Abstract: Conservation of ecosystem engineers, which modulates the surrounding habitat by causing physical state changes in biotic or abiotic materials, is important for maintaining the functional integrity of ecosystems. This study examined the effects of endangered freshwater pearl mussels (Margaritifera laevis and M. togakushiensis) on channel morphology and flow in a low-gradient sandy river. For this, we performed a field removal experiment of mussels using three treatments in twelve 10-m reaches. Mussel abundance … Show more

“…Their vulnerability is largely derived from their complex life cycle, which requires host fish parasitization during their larval (‘glochidial’) phase (the larva is called a ‘glochidium’) (Modesto et al, 2018). Many mussel populations face a high risk of extinction owing to recruitment failure (Varandas et al, 2013; Sousa et al, 2016; Miura et al, 2021). Their longevity (4–190 years) allows them to persist for a long time, even in non‐recruiting populations (Geist, 2010; Haag & Rypel, 2011).…”
