Environmental DNA, Volume 8, Issue 2, March/April 2026.We measured a positive linear relationship between eDNA concentration and abundance for larval Delta Smelt (Hypomesus transpacificus) with N = 1 larva exceeding the limit of detection for the novel qPCR assay. Field experiments quantified the probability of detection for eDNA sampling methods at known abundances and distances from source. ABSTRACT Rare

Do Snow‐Adapted Prey Facilitate Coexistence of the Sierra Nevada Red Fox With Sympatric Carnivores?
Molecular Ecology, Volume 34, Issue 20, October 2025.ABSTRACT Specialist species in alpine ecosystems may be increasingly threatened by climate‐driven habitat loss and encroachment by generalist competitors. Ecological theory predicts that niche differentiation through dietary specialisation can facilitate coexistence with generalist competitors.
