Seasonal and Within‐Day Variation on Hummingbirds Visits and Dominance Hierarchy in a Brazilian Cerrado Area

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT Plant‐hummingbird interaction networks can be influenced by environmental conditions and resources, which vary seasonally and daily. We aimed to understand how variations in these parameters across these two temporal windows influence patterns of plant‐hummingbird interactions and hummingbirds dominance hierarchies in a Brazilian Cerrado ...

Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...

Life history induces markedly divergent insect responses to habitat loss

Journal of Animal Ecology, Volume 95, Issue 1, Page 54-64, January 2026.
This study pioneers the use of deep learning to rapidly assess over 22,000 Amazonian insects, revealing life history‐dependent winners and losers from forest loss. It shows that terrestrial insects decline while aquatic insects thrive, with body size influencing dispersal, offering key insights for biodiversity conservation in tropical fragmented ...

Species functional traits affect regional and local dominance across western Amazonian forests

Journal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A

Diversity modulates above‐ground productivity in response to disturbances: The case of Iberian forests

Journal of Ecology, Volume 113, Issue 12, Page 3605-3621, December 2025.
We analysed whether forest productivity responses to disturbances were modulated by structural and functional diversity, as well as by functional dominance, and whether these responses vary among functional groups. Forest diversity can mitigate the negative effects of disturbances on productivity.

Dominancia social, valores y posicionamiento ideológico en jóvenes universitarios

Psicodebate, 2008
The theoryof Social Dominance (Sidanius & Pratto, 1999) postulates that group discrimination tends to be systematic because social ideologies help coordinate the actions of institutions and individuals. The acceptance of ideologies that legitimize inequality is in part determined by the general desire of individuals to dominate one group over another ...

Functional Diversity of Neotropical Aquatic Hyphomycetes: Insights Into Environmental Drivers

Biotropica, Volume 57, Issue 6, November 2025.
Subtropical streams host diverse hyphomycete assemblages than tropical one's. Larger saprotrophs with diverse conidia shapes dominate in subtropical areas. Cold and oxygenated waters have a positive effect on functional diversity. Poor litter in tropical favored the dominance of wood saprotrophs and endophytes.
