This study investigates how multiple stressors affect recruitment efficiency in endangered freshwater mussels, identifying parasitic and post-parasitic juvenile stages as critical bottlenecks.

The paper assesses recruitment status and host-fish limitation threats to endangered freshwater pearl mussels in eastern Hokkaido, finding low juvenile proportions and a positive link between juvenile presence and host-fish density.

This study identifies how volcanic rock-dominated watersheds create cold water refugia in mountain streams, which are more resilient to climate change than non-volcanic streams.

This study examines seasonal variations in 137Cs concentrations in freshwater charr, linking them to prey availability and metabolic rates at Fukushima and Gunma sites post-Fukushima accident.
