Group composition and its ontogenetic changes in marine pelagic fishes

This study examines group composition and its ontogenetic changes in two marine fish species, finding that group structure shifts from age/growth-similar individuals in juveniles to more random composition in sub-adults.

Dose-dependent effects of histone methyltransferase NSD2 on site-specific double-strand break repair

This study shows NSD2 has dose-dependent effects on DSB repair pathways, repressing non-c-NHEJ and promoting c-NHEJ while not affecting HR or total NHEJ efficiency.

A dynamic partitioning mechanism polarizes membrane protein distribution

This study identifies a dynamic partitioning mechanism that explains asymmetric membrane protein distribution during signaling events.

Highly structured habitats mitigate size-and growth-selective mortality of post-settlement juvenile fish

The paper examines how macroalgal habitat structure affects mortality and growth of juvenile fish, finding higher mortality in lower vegetation coverage cohorts and temperature-dependent growth effects.

Density-dependent attributes of schooling in small pelagic fishes

The paper examines density-dependent schooling behaviors in three small pelagic fish species, finding species-specific relationships between population density and school characteristics.

Stronger density-dependent growth of Japanese sardine with lower food availability: Comparison of growth and zooplankton biomass between a historical and current stock-increase period in the western North Pacific

The paper compares density-dependent growth of Japanese sardine in the western North Pacific during a historical stock-increase period and the current period, finding stronger density dependence in the 2010s linked to lower food availability.

Intra- and inter-specific density dependence of body condition, growth, and habitat temperature in chub mackerel (Scomber japonicus)

This study examines how density dependence affects body condition, growth, and habitat temperature in chub mackerel, finding that conspecific and heterospecific abundance negatively impact body condition more than temperature.

Length-length and length-weight relationships for four small pelagic fishes in the Kuroshio-Oyashio current system

The paper estimates length-length and length-weight relationships for four small pelagic fish species in the Kuroshio-Oyashio current system using measurements from 2020 surveys.

Spatio-temporal spawning patterns and early growth of Japanese sardine in the western North Pacific during the recent stock increase

This study examines changes in spawning patterns and early growth of Japanese sardine during a stock increase, finding that shifts in spawning areas and hatch dates correlate with recruitment success.

Solving the sex ratio scandal in Melittobia wasps

The paper resolves the sex ratio discrepancy in Melittobia wasps by showing that females adjust their sex ratio based on dispersal status and relatedness in natural settings, contrasting with laboratory experiments.

Evolution of nuptial gifts and its coevolutionary dynamics with "masculine" female traits for multiple mating

The paper models coevolutionary dynamics between nuptial gift size and female multiple mating propensity, showing that positive paternity gain from large gifts drives female competition and polyandry.
