Evaluating protected areas’ coverage of threats to terrestrial biodiversity

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Protected areas (PAs) are vital for biodiversity conservation and have expanded globally. However, increasing pressures on biodiversity make it difficult to achieve conservation goals. Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the ...

How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta‐analysis

open access: yesJournal of Ecology, Volume 113, Issue 10, Page 2875-2888, October 2025.
These results suggest that the fertilization effect of CO2 at the seedling stage may be limited when additional environmental stressors, such as drought, are present. The combined effect of drought, temperature and CO2 mainly resulted in additive effects, where each stressor independently influences plant performance rather than interacting to amplify ...

Environmental and human factors shape the trophic ecology of a widespread marine predator

open access: yesJournal of Animal Ecology, Volume 94, Issue 9, Page 1784-1799, September 2025.
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Rapid Ocean Warming Drives Sexually Divergent Habitat Use in a Threatened Predatory Marine Ectotherm

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
How ectothermic, mobile marine predators are responding to climate change is uncertain due to lack of species‐specific data, which can mask the true impact of this threat. We investigate the impact of environmental conditions and thermal extremes on the behavior and distribution of angelsharks, a highly threatened elasmobranch of global conservation ...
