Mapping the density of giant trees in the Amazon. [PDF]

New Phytol
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Interaction between floral rewards and floral symmetry shapes diversification dynamics in Amazonian trees. [PDF]

New Phytol
Summary Floral zygomorphy, or monosymmetry, is thought to have a positive effect on the diversification rates of angiosperms, but its true impact is still an open topic. Given the controversy surrounding this matter, our study evaluates whether rewards such as nectar and pollen produced by floral structures evolve in correlation with floral symmetry ...

Caatinga diaspores: Descriptive overview of dispersal units of seasonally dry tropical forests and woodlands. [PDF]

Ecology
Abstract Dispersal unit characteristics provide crucial insights into species ecology and are essential for the conservation and restoration of ecosystems. The Caatinga, the largest ecosystem of seasonally dry tropical forests and woodlands in South America, remains underrepresented in terms of dispersal unit data, which are often scattered across the ...

Across the edge: Spatial segregation drives community structure in tri-trophic multilayer networks at a forest-grassland edge. [PDF]

J Anim Ecol
This study reveals how forest–grassland edges act as ecological barriers that shape tri‐trophic interaction networks. Using multilayer network theory, it uncovers how species influence and biodiversity patterns emerge across spatial layers, offering novel insights into edge‐driven community assembly and conservation in fire‐prone mosaics.

Experimental Drought Suppresses Amphibian Pathogen Yet Intensifies Transmission and Disrupts Protective Skin Microbiome [PDF]

Global change biology.
This study used ecologically realistic enclosures with pumpkin toadlets to simulate short‐term drought conditions in Brazil's Atlantic Forest. Drought reduced the overall levels of a harmful amphibian fungus, but it also disrupted their protective skin‐associated bacteria and caused the toadlets to cluster in wet areas of the enclosures, which ...

Multiple facets of biodiversity are threatened by mining‐induced land‐use change in the Brazilian Amazon

Diversity and Distributions, Volume 29, Issue 9, Page 1190-1204, September 2023., 2023
Abstract Aim Mining is increasingly pressuring areas of critical importance for biodiversity conservation, such as the Brazilian Amazon. Biodiversity data are limited in the tropics, restricting the scope for risks to be appropriately estimated before mineral licensing decisions are made.

Promoting landscapes with a low zoonotic disease risk through forest restoration: The need for comprehensive guidelines

Journal of Applied Ecology, Volume 60, Issue 8, Page 1510-1521, August 2023., 2023
Our results contribute to a more comprehensive forest restoration planning, comprising multiple ecosystem services and resulting in healthier landscapes for both people and nature. Our framework could be integrated into the post‐2020 global biodiversity framework targets.
