Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Ecological Entomology, Volume 50, Issue 5, Page 886-898, October 2025.Low‐sodium females took significantly longer to start mating than high‐sodium females, but no pairings differed in the duration of copulation. Reproductive outputs, measured by number of clutches, hatching young, adult offspring and pupation time, did not differ across parental sodium pairings.

Complex relationship between soil fungi and conservation value assessments in boreal forests
Conservation Biology, Volume 39, Issue 4, August 2025.Abstract Large‐scale industrial forestry is a threat to biodiversity and imposes long‐lasting changes to many forested biomes. Preserving forests as reserves is an important component of the strategy for safeguarding forest biodiversity. Yet, the selection of forests of high biodiversity value is usually based on proxies (i.e., subsets of aboveground ...
