Hot spots in a cold river synchronize temporarily separated salmon runs in their offsprings development

This study identifies thermal hotspots in a river that influence salmon spawning site selection and fry emergence timing, showing how groundwater affects salmon development.

Cryptic connectivity between hyporheic and riparian zones via winged aquatic insects revealed by DNA barcoding

The paper identifies cryptic connectivity between hyporheic and riparian zones via adult aquatic insects using DNA barcoding and community surveys.

Multiple stressors and recruitment failure of long-lived endangered freshwater mussels with a complex life cycle

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

Recruitment status and host-fish-limitation threats to endangered freshwater pearl mussel (Margaritifera laevis) in eastern Hokkaido, northern Japan

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.

Relationship between salmon egg subsidy and the distribution of an avian predator

The paper examines how salmon egg availability affects brown dipper abundance and distribution, finding a strong correlation with spawning redds.

Long-term recoveries of forest ecosystem components after shallow landslides were asynchronized among slope positions

This study shows that forest recovery after shallow landslides occurs faster at lower slope positions due to richer disturbance legacies and stabilized soils.

Inferring future changes in gene flow under climate change in riverscapes

This study predicts future changes in gene flow for fluvial sculpin under climate change using riverscape genetics and hydrological models.

The role of geology in creating stream climate-change refugia along climate gradients

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.

A strategic sampling design revealed the local genetic structure of cold-water fluvial sculpin: a focus on groundwater-dependent water temperature heterogeneity

The study reveals a genetic structure in fluvial sculpin populations influenced by groundwater-dependent temperature heterogeneity, showing asymmetric gene flow rather than temperature-driven differentiation.

Sex, androgens and regulation of pulmonary AR, TMPRSS2 and ACE2

This study investigates sex differences in TMPRSS2 and ACE2 expression in human and mouse lungs and evaluates the effect of anti-androgens on these genes, finding no significant increase in TMPRSS2 but sex dimorphism in ACE2.

Belowground changes to community structure alter methane-cycling dynamics in Amazonia

The paper measures methane flux and microbial communities across land use changes in Amazonia, finding that pasture soils emit methane while forests act as sinks, with microbial shifts driving these changes.

Histone modification dynamics as revealed by a multicolor immunofluorescence-based single-cell analysis

This study introduces a multicolor immunofluorescence method to analyze histone modification dynamics in single cells, revealing changes during the cell cycle and validating histone demethylase targets.

Intra-individual variability of sleep and nocturnal cardiac autonomic activity in elite female soccer players during an international tournament

This study examines sleep patterns and nocturnal cardiac autonomic activity in elite female soccer players during a tournament, finding significant individual variability in sleep duration and heart rate variability.
