Body size is a better predictor of intra- than interspecific variation of animal stoichiometry across realms

The paper analyzes animal stoichiometry across species and body sizes, finding body size better predicts intraspecific than interspecific variation in elemental content.

Sedimentary DNA can reveal the past population dynamics of a pelagic copepod

This study uses sedimentary DNA to track past population dynamics of the copepod E. japonicus, finding correlations with in situ production and biomass but not resting eggs or growth rate.

Fish environmental DNA in lake sediment overcomes the gap of reconstructing past fauna in lake ecosystems

This study uses sedimentary environmental DNA to track historical fish abundance in Lake Biwa, showing a correlation between eDNA concentration and fish catch data.

Degradation modeling of water environmental DNA: Experiments on multiple DNA sources in pond and seawater

The paper experiments on eDNA degradation in pond and seawater, finding exponential decay for cell- and fragmental DNA-derived eDNA and validating an exponential degradation model.

Spatial structures of fungal DNA assemblages revealed with eDNA metabarcoding in a forest river network in western Japan

The paper investigates fungal DNA assemblages in river water using eDNA metabarcoding and finds they are more similar within than between branches and more similar between closer branches.

Biogeographic patterns of ectomycorrhizal fungal communities associated with Castanopsis sieboldii across the Japanese archipelago

The paper examines biogeographic patterns of ectomycorrhizal fungal communities associated with Castanopsis sieboldii across Japan, finding that host genotypes influence these patterns, though climatic and spatial factors have greater explanatory power.
