Signatures of Wild Animal Life in Earth's Landscapes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Animals shape Earth surface processes and landforms by displacing Earth surface materials and by making them more or less susceptible to geophysical processes. Despite increased recognition of the global significance of animal landscape “signatures”, analysis of their magnitude and generality has not been possible until now.

Mitochondrial function predicts dominance status in brown trout

Functional Ecology, Volume 40, Issue 4, Page 816-829, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In social hierarchies, winning contests confers better access to food, shelter and reproductive opportunities. Clear dominance relationships are often apparent even when opponents are matched for experience, age, size and other obvious characteristics.

No Groundwater, No Fish: The Critical Role of Groundwater in Supporting Non‐Glacial, Salmon‐Bearing Rivers in South‐Central Alaska

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Groundwater discharge plays an important role in the hydrologic and ecologic functioning of rivers including sustaining streamflow and related habitat year‐round. Simultaneously, groundwater supports the increasing demands of people as the global population continues to grow.

Development and Laboratory Validation of a Field‐Deployable CRISPR‐Cas12a eDNA Assay for Phylogeographic Lineage Detection in Arctic Char (Salvelinus alpinus)

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Environmental DNA (eDNA) tools are increasingly used for biodiversity monitoring, with most existing assays targeting species‐level identification. However, the use of eDNA to resolve intraspecific genetic variation remains rare and methodologically underdeveloped.

Brown Trout Abundance in Boreal Streams With Large Wood

Ecology of Freshwater Fish, Volume 35, Issue 2, April 2026.
ABSTRACT Large wood has been found to be a crucial component in riverine ecosystems. However, due to the heavy channelization of rivers and intensive forestry practices over the past few decades, the amount of large wood in these ecosystems has decreased worldwide. River restoration aims to mitigate the effects of channelization and restore the channel

Seasonal Variation of δ13C and δ15N in a Boreal Lake Fish Community—Year‐Round Patterns and Explanatory Variables

Ecology of Freshwater Fish, Volume 35, Issue 2, April 2026.
ABSTRACT Seasonal changes in freshwater ecosystems influence fish resource use through both environmental and biological factors, but year‐round studies that include ice‐covered months have been lacking. We investigated seasonal variation in the stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) using year‐round monthly sampling of the fish ...
