Selection of river crossing location and sleeping site by proboscis monkeys (Nasalis larvatus) in Sabah, Malaysia
The frequency of river crossings for focal monkeys in the BE‐Group was significantly higher at locations with narrow branch‐to‐bank distances, and sleeping sites locations that offer arboreal escape routes may protect proboscis monkeys from leopard attack. Expand
Survival of Glochidial Larvae of the Freshwater Pearl Mussel, Margaritifera laevis (Bivalvia: Unionoida), at Different Temperatures: A Comparison Between Two Populations With and Without Recruitment
A trade-off is suggested between high fertility and low glochidial survival rate in Margaritiferidae, which tends to be shorter than in other families in Unionoida. Expand
Growth parameters of endangered freshwater pearl mussel (Margaritifera laevis, Unionoida)
Results suggest that margaritiferid mussels in southern regions such as M. laevis in Japan and M. margar itifera in Spain may be particularly vulnerable when conditions are unsuitable for juvenile mussels for prolonged periods. Expand
Impacts of invasive crayfish (Pacifastacus leniusculus) on endangered freshwater pearl mussels (Margaritifera laevis and M. togakushiensis) in Japan
This study shows that the presence of invasive crayfish reduces freshwater pearl mussel populations by damaging the shell margins and/or killing the mussels. Expand
New Record of the Freshwater Pearl Mussel Margaritifera togakushiensis from Northern Sakhalin, the Russian Far East
This paper is the first report of the freshwater mussel Margaritifera togakushiensis from northern Sakhalin. Species identification was performed based on shell characteristics. Twenty six deadExpand
Habitat Characteristics Influencing Distribution of the Freshwater Mussel Pronodularia japanensis and Potential Impact on the Tokyo Bitterling, Tanakia tanago
The physical habitat characteristics associated with spatial distribution patterns of the freshwater mussel Pronodularia japanensis, which is used for oviposition by the Tokyo bitterling Tanakia tanago, were investigated in a small stream within aTokyo bitterling protected area and correlations suggest that the population dynamics of mussels and Tokyo bitterness may be influenced by changes in stream sediment conditions.

Host Fish Species for the Glochidia of Anodonta japonica Inhabiting Drainage Ditches for Rice Cultivation in Hikone City
Determining the hosts for individual mussel species represents a very important ecological study on Unionidae as wel as other families in the Unionoida. Expand
Research priorities for freshwater mussel conservation assessment
Freshwater mussels are declining globally, and effective conservation requires prioritizing research and actions to identify and mitigate threats impacting mussel species. Conservation prioritiesExpand
