Sample size for estimating average productive traits of pigeon pea

Ciência Rural, 2016
: The objectives of this study were to determine the sample size, in terms of number of plants, needed to estimate the average values of productive traits of the pigeon pea and to determine whether the sample size needed varies between traits and between

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

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 ...
