Who prefers the dark? Daily activity of dung beetles from an Amazonian region

open access: yesEcological Entomology, Volume 51, Issue 3, Page 609-613, June 2026.
Daily activity patterns shape how dung beetle species coexist in Amazonian forests, revealing temporal niches that reduce competition and structure biodiversity. We compared species richness, abundance and assemblage composition of dung beetles sampled during day and night in a conserved terra‐firme forest in the Brazilian Amazon. Although richness and

Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2946-2965, June 2026.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

From Natural to Human‐Dominated Seascapes: Habitat Loss for Guiana Dolphins Over Two Decades

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Changes in natural environments, such as coastal and marine zones, caused by human activities impact the quality of habitats and their inhabitants, ultimately jeopardising species conservation. As human activity is ever‐increasing, it is imperative to understand how multiple stressors, such as shipping, fisheries and pollution, affect marine ...

American manatees adjust their diet composition and trophic niche breadth across different coastal regions

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Marine mammals can exhibit high plasticity in foraging strategies, but how such plasticity is driven by environmental conditions is poorly understood. The American manatee (Trichechus manatus), a large, endangered herbivore, inhabits marine, estuarine, and freshwater environments.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Joint social‐ecological outcomes of private land conservation: An evidence synthesis with a well‐being perspective

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1066-1084, May 2026.
Abstract Private land conservation (PLC) can contribute to sustainability by improving biodiversity and human well‐being but can also result in negative outcomes for people and nature if poorly designed. Informing PLC design to achieve objectives for joint biodiversity and well‐being is challenging because most evaluations assess ecological and social ...

Manejo integrado do fogo e a erradicação de mega-incêndios na Estação Ecológica Serra Geral do Tocantins, Jalapão, Brasil

open access: yesBiodiversidade Brasileira, 2019
Nossa proposta foi demonstrar como diferentes abordagens de gestão do fogo na Estação Ecológica Serra Geral do Tocantins (EESGT) se relacionam com o tamanho e ocorrência de mega-incêndios nessa unidade de conservação (UC).

Acclimatisation duration, not just release type, drives post‐release settlement in a large‐scale carnivore reintroduction programme

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...

Wide variation in hydraulic safety margins across and within southern Amazon forests

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Site‐specific conditions and species identity were the main drivers of variation in Ψdry and HSM50 in southern Amazonian trees, but played a weaker role in explaining Ψ50. Ψpredawn strongly predicted HSM50. Across the Amazon, Ψ50_CWM and Ψdry_CWM became more negative with increasing MCWD, whereas HSM50_CWM showed no significant relationship with MCWD ...
