Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

Ecological Entomology, Volume 51, Issue 2, Page 235-249, April 2026.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, Volume 168, Issue 2, Page 571-587, April 2026.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

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 ...

Beyond Ecology: How Environmental and Social Landscapes Shape Tropical Forest Restoration in Southeast Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Restoration was more associated with environmental variables than socioeconomics. Active restoration was utilized in degraded areas and pasture abandonment favored natural regeneration. Successful tropical restoration is dependent on a complex interdependent mix of factors.

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

Biotropica, Volume 58, Issue 2, March 2026.
Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over
