The Miners of South America: Impacts of Climate Change on the Distribution of Geositta Miners Along Elevational Gradients

Biotropica, Volume 58, Issue 1, January 2026.
We modeled the current and future distributions of seven Geositta species along elevational gradients in South America under two climate change scenarios. Our results show that most species are projected to lose suitable habitats, particularly under the high‐emission scenario, with distinct responses between lowland and highland taxa.

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

Macroclimatic niche similarity and species relatedness shift their influence on species co‐occurrence in bryophyte forest communities across scales

Journal of Ecology, Volume 113, Issue 6, Page 1546-1559, June 2025.
The relationship between epiphytic bryophyte species associations changes with scale. Macroclimatic niche similarity strongly influences co‐occurrence globally but less so at smaller scales. Most species interactions are positive or neutral across scales, though ~7% shift from positive at microhabitat to negative at regional scales, highlighting scale ...

Plant functional traits and the entangled phenotype

Functional Ecology, Volume 39, Issue 5, Page 1144-1159, May 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Integrated phenotypes consist of multiple traits with enough coordination within and across organs to result in viable individuals, which not only respond to the surrounding environment but also modify it in myriad ways.
