BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1556-1584, May 2026.
Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...

A response to ‘Quantifying phenotypic plasticity at multiple levels—A comment on Gómez et al.’

Functional Ecology, Volume 40, Issue 3, Page 560-562, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In this reply, we clarify several conceptual misunderstandings raised in response to our Perspective on quantifying phenotypic plasticity. We emphasize that our central argument concerns the rigorous estimation of the magnitude of plasticity, rather than its mere ...
