Moth Communities Reveal High Stability Despite Ongoing Compositional Shifts Over Five Years Following Hurricane Disturbance

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We examined the temporal dynamics and ecological stability of tropical forest moth communities using a unique dataset spanning 6 months before and up to 5 years after two extreme hurricanes. While abundance and richness recovered within 2 years, species composition continued to shift, indicating ongoing reassembly with a directional trajectory toward ...

Recovery mode: Marine protected areas enhance climate resilience of invertebrate species to marine heatwaves

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 1879-1893, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Marine protected areas (MPAs) can promote population recovery from climate change impacts by reducing local stressors like fishing. However, with extreme climatic events such as marine heatwaves (MHWs) increasing in frequency and duration, it remains unclear whether ...

When can we expect negative effects of plant diversity on community biomass?

open access: yesJournal of Ecology, Volume 113, Issue 8, Page 1955-1969, August 2025.
Understanding the functional consequences of biodiversity loss is critical but we need to be clear about what type of biodiversity change we are measuring and to focus on the loss of stably coexisting core species. Abstract Although experiments overwhelmingly show biodiversity increases ecosystem functioning, relationships in natural communities are ...
