Burn them all? Use and efficacy of fire as a tool for grassland restoration

open access: yesRestoration Ecology, Volume 33, Issue 7, September 2025.
Grassland ecosystems have suffered significant degradation and restoring them is fundamental to fight against climate change and biodiversity loss. Fire is an important component in the evolution and management of grasslands worldwide and can potentially be used to restore grasslands. In this paper, we present a systematic literature review to know how

Surviving in the Amazon Arc of Deforestation: Richness and Defaunation of Mammals in Priority‐Protected Areas of the Brazilian Midwest

open access: yesAustral Ecology, Volume 50, Issue 7, July 2025.
We found rich and compositionally different assemblages of medium and large‐sized mammals in protected areas on the southern edge of Amazon. However, both have high rates of mammal defaunation. We argue that anthropogenic threats in the Amazon Arc of Deforestation are eroding large ungulate populations, especially peccaries.

Fire Effects on Bird Communities From Seasonally Flooded Forests Along Amazonian Black Water Rivers of the Negro River Basin

open access: yesDiversity and Distributions, Volume 31, Issue 5, May 2025.
ABSTRACT Aim Fire significantly contributes to Amazonian degradation, with igapó forests (seasonally flooded by blackwater rivers) being especially vulnerable. Igapó forests support species adapted to seasonal flooding, making fire a critical threat to these specialised organisms.

Tree traits are a stronger predictor of bee traits and species richness than taxonomic diversity

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 281-292, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits help to understand biological diversity and the mechanism by which ecological communities are structured and how they respond to the environment. For example, the high tree species diversity within tropical forests can be grouped into a few functional ...

Análise espaço-temporal das características do mangue urbano no estuário do Pina (Pernambuco)

open access: yesRevista Brasileira de Meio Ambiente, 2018
A modificação do manguezal preservado para área degradada se reflete na alteração dos diversos processos na interface atmosfera-vegetação, e consequentemente, no microclima da floresta de mangue, afetando processos ecológicos como a regeneração e o ...
