Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1270-1285, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities.

estar: An R package to measure ecological stability

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 4, Page 1090-1100, April 2026.
Abstract Assessing ecological stability is a key task in biodiversity monitoring and conservation. Quantifying stability is not trivial because its different aspects can be measured with various properties. However, to date, no software enables measuring different stability properties on ecological time‐series data.
