Integrating eDNA and community science to monitor urban Odonata diversity

Insect Conservation and Diversity, Volume 19, Issue 1, Page 84-92, January 2026.
Environmental DNA captured rare and underrepresented taxa often missed by community science observations. Community science revealed adult‐stage observations across a broader temporal window. Integrating both methods improved detection across life stages, seasons, and species prevalence.

Where Do You Fly From? Assessing Aerial Dispersal in Temporary Rivers Using Stable Isotopes

Freshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Dispersal is a crucial ecological process that facilitates gene flow and species exchange within ecosystems. In temporary rivers (TRs), dispersal is a key driver of community assembly because it determines the ability of the organisms to adapt to seasonal drying and maintain stable populations.
