SDM meets eDNA: optimal sampling of environmental DNA to estimate species–environment relationships in stream networks

open access: yesEcography, Volume 2025, Issue 5, May 2025.
Species distribution models (SDMs) are frequently data‐limited. In aquatic habitats, emerging environmental DNA (eDNA) sampling methods can be quicker and more cost‐efficient than traditional count and capture surveys, but their utility for fitting SDMs is complicated by dilution, transport, and loss processes that modulate DNA concentrations and mix ...

Continental‐Scale Assessment of Climate‐Driven Marine Species Range Extensions Using a Decade of Citizen Science Data

open access: yesDiversity and Distributions, Volume 31, Issue 4, April 2025.
ABSTRACT Aim Climate‐driven extensions of species distributions have serious consequences for human wellbeing and ecosystems. The recent growth of citizen science data collection represents an underutilised resource for the early detection of marine species range extensions (i.e., expansion of species' distributions at the poleward edge) that can ...
