Testing the size‐grain hypothesis in a generalist predator: The case of an ant species in the Brazilian savannah

Journal of Zoology, Volume 328, Issue 3, Page 234-247, March 2026.
In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...

Competitor Richness Outweighs Climate and Land Cover in Explaining Abundance Variation of a Neotropical Fruit Bat

Austral Ecology, Volume 51, Issue 1, January 2026.
ABSTRACT Understanding which processes regulate spatial variation in species abundance across their ranges is key in ecology. Species abundances may be affected by several factors, such as climate, elevation, land cover, species interactions and habitat protection status. However, few studies have focused on these effects synergistically across species

Functional Diversity of Neotropical Aquatic Hyphomycetes: Insights Into Environmental Drivers

Biotropica, Volume 57, Issue 6, November 2025.
Subtropical streams host diverse hyphomycete assemblages than tropical one's. Larger saprotrophs with diverse conidia shapes dominate in subtropical areas. Cold and oxygenated waters have a positive effect on functional diversity. Poor litter in tropical favored the dominance of wood saprotrophs and endophytes.

Precipitation and Temperature‐Dependent Locomotor Performance Drive the Abundance of a Neotropical Lizard

Biotropica, Volume 57, Issue 6, November 2025.
We investigated how climate and ecophysiology affect the demography of the lizard Tropidurus oreadicus in the Brazilian Cerrado. While lizards were more frequently captured in the dry season, their abundance peaked during the rainy season when their locomotor performance was highest.

Surviving in a Warming and Fragmented World: Long‐Term Population Dynamics of the Lizard Gonatodes humeralis

Austral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Climate change presents significant challenges to species survival; however, the long‐term effects on tropical lizard populations remain poorly understood. Previous studies have predicted contrasting outcomes, with some forecasting a high risk of extinction due to rising temperatures, while others suggest greater resilience in tropical ...

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...
