Local knowledge enhances the sustainability of interconnected fisheries

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our modelling approach allows managers to compare alternative conservation strategies under different socio‐ecological scenarios, highlighting trade‐offs and guiding investment of effort and resources. While immediately valuable for pirarucu management in the Middle Juruá, the framework scales across tiers of applicability, each requiring progressively

Precipitation and Temperature‐Dependent Locomotor Performance Drive the Abundance of a Neotropical Lizard

Biotropica, Volume 57, Issue 6, November 2025.
We investigated how climate and ecophysiology affect the demography of the lizard Tropidurus oreadicus in the Brazilian Cerrado. While lizards were more frequently captured in the dry season, their abundance peaked during the rainy season when their locomotor performance was highest.

Surviving in a Warming and Fragmented World: Long‐Term Population Dynamics of the Lizard Gonatodes humeralis

Austral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Climate change presents significant challenges to species survival; however, the long‐term effects on tropical lizard populations remain poorly understood. Previous studies have predicted contrasting outcomes, with some forecasting a high risk of extinction due to rising temperatures, while others suggest greater resilience in tropical ...

Migration Patterns of Epiphyllous Bryophyte Metapopulations in Amazonian Fragmented Landscape Inferred From Census and Genomic Data

Biotropica, Volume 57, Issue 5, September 2025.
We examined the long‐term genetic consequences of habitat fragmentation on two epiphyllous bryophyte species in experimentally fragmented Amazonian forests. Using genotyping and demographic data, we found species‐specific responses and metapopulation dynamics in relation to their mating system.

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 ...
