Wasp and Ant Nests: Who Really Protects Whom? New Insights From Amazonian Forests
Austral Ecology, Volume 51, Issue 5, May 2026.ABSTRACT Studies of animal behaviour are often biased towards species that are large‐bodied or have broad geographic ranges, as these are easier to observe in nature. Consequently, our understanding of behavioural ecology is shaped by such biases, even though these studies have provided important insights.

Austral Ecology, Volume 51, Issue 1, January 2026.ABSTRACT Understanding which processes regulate spatial variation in species abundance across their ranges is key in ecology. Species abundances may be affected by several factors, such as climate, elevation, land cover, species interactions and habitat protection status. However, few studies have focused on these effects synergistically across species

Caminhos de Geografia, 2011 Os Flebotomíneos ocupam a maioria das regiões compostas por vegetação, com exceção de regiões polares e oceânicas. Algumas espécies são vetores de uma doença endêmica, a leishmaniose cuja transmissão é influenciada por diversos padrões espaço-temporal ...

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.
