Spatial capture‐recapture can improve environmental impact assessments for large carnivores

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Most Environmental Impact Assessments for large carnivores rely on summary statistics or relative abundance indices, all of which ignore imperfect detection and may lead to biased and unreliable conclusions about population status and infrastructure impacts. By applying spatial capture‐recapture (SCR) models to georeferenced genetic data from wolves in

Temporal Dynamics of a Neotropical Plant‐Hummingbird Interaction Network

Austral Ecology, Volume 50, Issue 7, July 2025.
Using an unprecedented sampling effort we evaluated network structure and dynamics of plant‐hummingbird interactions over 1 year in the Brazilian hyperdiverse Campos Rupestres. Network structure presented remarkable temporal change, showing that tropical communities can also be strongly influenced by climate.

Hard Mating Aggregation as Evidence of Polyandry in the Red‐Tailed Boa, Boa constrictor (Squamata: Boidae), in a Brazilian Caatinga Population

Ecology and Evolution, Volume 15, Issue 6, June 2025.
This study reports a reproductive aggregation of a female Boa constrictor with five males in the Brazilian Caatinga. The observation reinforces the evidence of a polyandrous system, favoring larger females that copulate with different males. Our record highlights the influence of sexual size dimorphism in the formation of aggregations.

When do citizen scientists record biodiversity? Non‐random temporal patterns of recording effort and associated factors

People and Nature, Volume 7, Issue 4, Page 860-870, April 2025.
Abstract Citizen science data are increasingly used for ecological research, biodiversity conservation and monitoring. However, these data often present significant analytical challenges due to uneven recording efforts by citizen scientists. Biases caused by intra‐annual differences in levels of recording activity can be particularly severe, hindering ...

Rainfall seasonality shapes belowground root trait dynamics in an Amazonian tropical rainforest: A test of the stress‐dominance hypothesis

Functional Ecology, Volume 39, Issue 3, Page 799-812, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stress‐dominance hypothesis (SDH) predicts that trait variation at the community level increases with the availability of limiting resources, driving spatial and temporal patterns in above‐ground plant functional trait expression.
