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.

Use of a Cytobrush for Sampling the Ear Canal of Dogs With Otitis Externa

Veterinary Dermatology, Volume 37, Issue 2, Page 227-235, April 2026.
Cytological examination of the ear canal is essential for evaluating dogs with otitis externa (OE). The conventional sampling method uses a swab. However, the cytobrush (gynaecological cervical brush), already used for cytological collection from other anatomical sites, has not been adequately investigated for this purpose in dogs with OE.

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 ...

Monitoring small‐scale fisheries through participatory, app‐based surveys in the tropical archipelago of São Tomé and Príncipe

Conservation Science and Practice, Volume 8, Issue 3, March 2026.
Small Island Developing States have limited capacity to monitor Small Scale Fisheries, despite their high dependence on marine resources. Participatory monitoring of Small Scale Fisheries can fill data gaps while integrating resource users into fisheries management.

Níveis críticos de fósforo, para milho, em casa de vegetação, de acordo com a sua localização no solo Critical phosphorus levels for greenhouse-grown corn, as a function of its placement in the soil

Revista Brasileira de Ciência do Solo, 2006
A aplicação localizada de P no solo apresenta grande influência sobre sua disponibilidade, pois diminui as reações de adsorção, precipitação e fixação, em virtude da redução da superfície de contato com o solo.

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.

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

Austral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.
