Abstract:
... The cold hardiness of arthropods is an important characteristic associated with overwintering success. Cold‐tolerant stages affect overwintering strategy, especially in arthropods that continuously feed on evergreen host plants in temperate regions. However, cold hardiness to mildly low temperature is rarely investigated. In the present study, we estimate the stage‐specific cold hardiness of a pop ...

Abstract:
... Insect–host fungus associations are important ecological features that affect population dynamics and interspecific interactions. However, details of host fungus relationships in fungivorous beetles remain unclear due to incompletely revised taxonomy and insufficient host records. We conducted a taxonomic study of the ciid beetle Octotemnus laminifrons (Coleoptera: Ciidae) and its cryptic species ...

Subject:
concrete; dams (hydrology); rivers; sediments; shrews; streams; surveys; Japan
Abstract:
... The concrete walls of check dams are considered a physical barrier for aquatic and semiaquatic animals that inhabit mountain streams. Traveling behaviors around concrete check dams by the Japanese water shrew Chimarrogale platycephalus, a semi-aquatic mammal, were directly observed via radio-tracking in Kamikoshi Stream in central Honshu, Japan. Traveling behaviors were mainly observed on the wet ...
