Long‐term jaguar demography underscores the ecological value of Amazonian floodplains

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results provide the first estimates of recruitment and apparent survival for Amazonian jaguars, key parameters for guiding conservation. We show that seasonal wetlands—the Amazonian floodplain forest and reported estimates from Pantanal and the Llanos—harbour the highest jaguar densities across the species' range.

Ant‐Mediated Ecosystem Functions Along a Tropical Elevational Gradient

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Elevational gradients are excellent systems to study biodiversity variation, yet the ecosystem functions performed by animals along these gradients are poorly understood. We assessed tropical elevational patterns of ant‐mediated seed removal, insect predation and the phylogenetic diversity of the local ant assemblages performing these ...

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

Ecography, Volume 2026, Issue 6, June 2026.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Plantas alimentícias e paisagens: uso e conservação no Sertão do Ubatumirim, Ubatuba, Brasil

Desenvolvimento e Meio Ambiente, 2019
O manejo de plantas alimentícias por populações tradicionais é crucial para a conservação da biodiversidade, especialmente em áreas consideradas “hotspots”, onde a biota única possui alto grau de endemismo.

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

People 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 ...

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

Journal 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 ...

Into the Darkness: Unveiling Unexpected Records of the Nonnative Millipede Prosopodesmus jacobsoni Silvestri, 1910 (Polydesmida: Haplodesmidae) in Brazilian Caves

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT This study expands the known distribution of the nonnative millipede Prosopodesmus jacobsoni in Brazil and reports its presence in cave environments for the first time in the country. Based on recently collected material and historical records, the species is shown to maintain stable populations in subterranean systems in the states of ...

A new method to control the invasive sun corals (Tubastraea spp.): Underwater compressed‐air blasting

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater compressed‐air blasting is a novel method developed to control invasive sun corals (Tubastraea spp.). The technique removes coral soft tissue without fragmenting colonies, reducing the risk of regeneration and accidental spread. This approach offers a safer and practical tool for managing invasive corals in natural reefs and biofouling ...
