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

Ibis, EarlyView.
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.

Abundance and Seasonal Dynamics of Guiana Dolphins (Sotalia guianensis) in Southern Brazilian Estuarine and Adjacent Coastal Waters

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Estimating population parameters is crucial for understanding species dynamics and assessing anthropogenic impacts, thereby supporting conservation efforts. We evaluate key population parameters—group structure, abundance and capture–recapture probabilities—of the Guiana dolphin in the Paranaguá Estuarine Complex and adjacent coastal waters ...

The role of tropical forest fragment vegetation in maintaining arthropod diversity and spillover to adjacent sugarcane fields O papel da vegetação de fragmentos de floresta tropical na manutenção da diversidade de artrópodes e na sua disseminação para campos de cana‐de‐açúcar adjacentes

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 82-93, February 2026.
Tree diversity increases arthropod richness and the abundance of beneficial arthropod groups within Atlantic Forest fragments. Higher insect richness in forest fragments is associated with greater richness in adjacent sugarcane fields, and both habitats share insect families, suggesting spillover.
