Climate and Land‐Use Change May Reshape the Biogeography of Freshwater Crabs Across China

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We employed ensemble species distribution models to investigate how climate and land‐use change will impact habitat suitability for two freshwater crab families (Potamidae and Sesarmidae) across China. Temperature emerged as the dominant driver, with cropland and urban land having strong, family‐specific effects on suitability. Future scenarios predict

Intrapopulation Metabolic Variation Reflects Growth Differences: A Cross‐Sectional Study on Gammarides

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
For the first time in Gammarus insensibilis, a single‐organism 1H NMR metabolomics approach was applied to investigate the intrapopulation variability in growth trajectories showing how divergent size classes, despite being of the same age, reflect alternative resource‐allocation strategies.

Catchment Influences on Carbon Stable Isotope Variation in Trout; Might It Be Methane?

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Trout stable carbon isotope values vary significantly and appear to relate to catchment characteristics. Low carbon stable isotope values are linked to catchments with low drainage soil and high cover of pasture land use. This is likely to be linked to high levels of methane‐derived carbon entering the stream food web.

A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring

open access: yesEcography, Volume 2026, Issue 5, May 2026.
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.

Comparative Assessment of Freshwater Biodiversity in Los Morales Reservoir (Madrid) Using eDNA Collected From Sponges and Water Filtration

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Filters and freshwater sponge tissue recover a comparable number of taxa through eDNA metabarcoding. Filters detect more taxa, followed by sponge tissue when host‐blocking primers are used. Each method reveals different community compositions, so combining both approaches is recommended to achieve a more realistic representation of the metazoan ...

Long-Term Eutrophication in Mesotrophic–Eutrophic Lake Kawaguchi, Japan, Based on Observations of the Horizontal Distribution of Profundal Chironomid Larvae and Oligochaetes

open access: yesLimnological Review
Many researchers have used the species composition, relative abundance and distribution pattern of profundal benthic macroinvertebrate communities in particular, especially chironomid fauna, as indicators of the trophic state and pollution of lakes.
