Spatial capture‐recapture can improve environmental impact assessments for large carnivores

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Most Environmental Impact Assessments for large carnivores rely on summary statistics or relative abundance indices, all of which ignore imperfect detection and may lead to biased and unreliable conclusions about population status and infrastructure impacts. By applying spatial capture‐recapture (SCR) models to georeferenced genetic data from wolves in

Environmental DNA Template Variation: Its Relevance for Species Detection and Conservation

Freshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Accurate species monitoring is foundational for understanding and assessing species extinction risk. Environmental DNA (eDNA) based species detection methods have been proposed as fast and powerful biodiversity monitoring tools. Yet, these methods are susceptible to errors that might hinder the assessment of species extinction risk.
