Community‐level effects of Müllerian mimicry on pollinator diversity and functioning

Functional Ecology, Volume 40, Issue 3, Page 599-610, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Müllerian mimicry, a mutualistic interaction in which harmful species evolve similar warning signals, is often accompanied by niche divergence among mimetic species. While these aspects have traditionally been studied in an evolutionary context, their community‐level ...

Integrated demographic strategies are more strongly associated with variation in conspecific density dependence than single traits in tropical tree seedlings

Journal of Ecology, Volume 114, Issue 2, February 2026.
Species‐specific conspecific negative density dependence (CNDD) varied widely among tropical tree species. CNDD was strongest in fast‐growing species and tall, long‐lived pioneers, weakly related to most functional traits except wood density and strongest in rare species. These results show that integrated life‐history strategies explain CNDD variation

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.

Climate Change Will Resize and Reshape Plant–Hummingbird Networks in the Atlantic Forest

Diversity and Distributions, Volume 32, Issue 1, January 2026.
ABSTRACT Aim To assess how climate change could reshape plant–hummingbird interaction networks in the Atlantic Forest by predicting shifts in species co‐occurrence and evaluating changes in network structure. Location Atlantic Forest, South America.

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 ...

Distribuição de abundância de espécies da comunidade arbórea do topo de um morro na floresta estacional subtropical

Ciência Rural, 2015
Modelos ecológicos de distribuição de espécies (DAEs) em uma comunidade arbórea foram investigados para constatar: (i) se as variáveis ambientais são divididas de maneira estocástica e de modo similar entre as espécies; (ii) se cada espécie exaure mais ...

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.

Uso de hábitat de dos ecotipos de toninas (Tursiops truncatus) en el golfo de California, México

Revista Mexicana de Biodiversidad, 2016
En el golfo de California se han descrito 2 ecotipos de toninas (costero y oceánico) y la mayoría de investigaciones son de regiones costeras. Este estudio analiza si 10 variables ambientales (profundidad, color del mar, visibilidad, estado del mar ...
