Landscape configuration and soil properties shape ant‐mediated seed dispersal in tropical dry forest agricultural landscapes

Journal of Animal Ecology, Volume 95, Issue 8, Page 1476-1487, August 2026.
We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

A Survey of Eyeless Pseudosinella Schäffer, 1897 (Collembola: Entomobryidae) From Brazil Reveals a New Cave‐Dwelling Species From Minas Gerais State

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Herein, a new species of Pseudosinella is described from Minas Gerais State, Brazil. This was possible after reanalysing six species similar to the new species: Pseudosinella alfanjeunguiculata Bellini, Cipola & Souza; Pseudosinella aphelabiata Bellini, Cipola & Souza; Pseudosinella diamantinensis Bellini, Cipola & Souza, 2020; Pseudosinella ...

Marine Heatwaves Overwhelm the Buffering Benefits of Marine Protected Areas: Two Decades of Collapse in a Mediterranean Gorgonian

Global Change Biology, Volume 32, Issue 8, August 2026.
Two decades of monitoring across the north‐western Mediterranean reveal a 45% regional biomass loss of the foundation gorgonian Paramuricea clavata, driven by increasingly frequent marine heatwaves. Protection sustained higher biomass but could not halt decline, underscoring the urgent need to pair conservation with climate action to preserve red ...

Imaging diagnosis of probable osteomyelitis in a 9-month-old infant from prehistoric Brazil: A brief history of healthcare in ancient times

Revista Argentina de Antropología Biológica
Individual 9, a 9 ± 3-month-old infant from the Middle-Holocene (6,650-6,170 years BP) found in Toca do Enoque rock-shelter in Piauí, Brazil, showed significant pathological bone changes and received exceptional mortuary treatment.

Carbon Stocks in Sugarcane Biomass and Their Implications on Land Use Change CO2 Balance in Brazil

GCB Bioenergy, Volume 18, Issue 8, August 2026.
This paper develops a regionalized carbon stock factor for sugarcane biomass in Brazil, showing that sugarcane cultivation can lead to net carbon removal in most municipalities. The findings improve greenhouse gas inventories and support bioenergy policies by providing more accurate, spatially resolved estimates for land use change emissions.

Spatial Scale Modulates the Effect of Habitat Amount on Diversity Patterns of Arachnid Assemblages Across Different Brazilian Ecosystems

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120

Gastrointestinal Parasites in Free‐Ranging Saguinus ursulus From the Eastern Brazilian Amazon: First Report of Prosthenorchis sp.

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Enteroparasites were investigated in free‐ranging Saguinus ursulus from the eastern Brazilian Amazon. Parasites were detected in 76.5% (13/17) of capture events, with Prosthenorchis sp. most frequently detected (58.8%; 10/17). Animals showed good body condition and no clinical abnormalities.

Occurrence of Antibodies Anti‐Toxoplasma gondii in Captive Non‐Human Primates From Pernambuco State, Brazil

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Wildlife captive populations are important tools for threatened species conservation, and early identification of diseases must be prioritized. In this study, we test for the presence of anti‐Toxoplasma gondii antibodies in non‐human primates at a Zoo from Pernambuco State, Brazil.
