Urban rendezvous: Spatiotemporal overlap is more important than abundance and trait matching for urban plant–pollinator interactions

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our study shows that the generalized structure of urban plant–pollinator interactions is mirrored in the mechanisms that shape them, as interactions are governed primarily by less restrictive drivers such as abundance and spatiotemporal overlap rather than by trait matching.

The Miners of South America: Impacts of Climate Change on the Distribution of Geositta Miners Along Elevational Gradients

open access: yesBiotropica, 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.

Estudo fitossociológico nas regiões de Carajás e Marabá - Pará, Brasil [PDF]

open access: yesActa Amazonica, 1999
O estudo fitossociológico levou em consideração duas áreas localizadas em Carajás e Marabá, na região sul do Pará. A amostragem abordou dois níveis: 1) Indivíduos com DAP ≥ 20cm em parcelas de 20m x 200m e, II) Indivíduos com 5cm ≤ DAP ≤ 20cm em duas sub-

Temporal Changes in Land Use Highlight the Vulnerability of Highland Grasslands in Protected Areas in Southern Brazil

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Subtropical Highland Grasslands showed greater net conversion than Mixed Ombrophilous Forest across our study PAs. In one PA created to conserve Highland Grasslands, net grassland loss inside the PA exceeded loss in adjacent buffer zones during the study period.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

open access: yesJournal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still
