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.

Groundwater Contributions to Daily Nitrogen and Phosphorus Loads and Implications for Prediction in Watersheds in South Korea

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Understanding watershed water quality dynamics is essential for sustainable management, yet accurate nutrient load prediction remains challenging under strong inter‐annual variability. To address this limitation, this study presents a hybrid modelling framework that integrates baseflow information into a machine‐learning structure to improve ...

Design and Application of a Genome‐Wide SNP Array to Improve Conservation Outcomes in the Critically Endangered Southern Corroboree Frog

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Species‐specific genomic information has the potential to transform modern conservation management strategies through improved genomic assessment and management outcomes. Gaining genomic insights into genetic diversity, adaptability and potential resilience against infectious diseases is essential to enhance conservation efforts for threatened

Comparative Multi‐Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Vital yet Fragile: Informal Networks of Support Among Young People Navigating Long Covid

Health Expectations, Volume 29, Issue 2, April 2026.
ABSTRACT Introduction Young people living with Long Covid face challenges accessing health care and social support. Previous qualitative research in the UK has described the ‘invalidation’ of Long Covid illness experience. It has been said that there is a ‘double invisibility’ produced by narratives that minimise the effects of Covid‐19 among young ...
