Better Alone Than in Bad Company: Trophic Ecology of Co‐Occurring Invasive and Native Crayfish
Ecology and Evolution, Volume 15, Issue 5, May 2025.This study investigated and compared trophic interactions between invasive signal crayfish and native white‐clawed crayfish at sites of co‐occurrence and in allopatry. The presence of crayfish plague, body condition, and trophic niche traits were explored as possible factors that make invasive signal crayfish a strong competitor, enhancing its ...

eDNA‐Based Detection of Invasive Crayfish and Crayfish Plague in Estonia
Environmental DNA, Volume 7, Issue 3, May–June 2025.Our study explored the potential of integrating the eDNA approach into ongoing annual monitoring programs for invasive crayfish species and A. astaci. Crayfish eDNA was detected in 9 out of 14 water bodies where presence was confirmed by trapping, yielding 64% detection efficiency. eDNA from A.

Ecology Letters, Volume 28, Issue 1, January 2025.We test how reproductive interference from inter‐species mating between sympatric Caenorhabditis nematodes can influence species coexistence and exclusion. We demonstrate that females from the species with higher intrinsic population growth experience reduced lifespan and fecundity due to incomplete interspecies mate discrimination that leads to ...
