Restoration age, distance from reference ecosystems, and host plant feeding guilds shape the diversity of frugivorous butterflies in ecological restoration areas in the Atlantic Forest

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...

Guild‐Specific Frog Responses to Natural Habitat Structure Gradients in an Atlantic Forest Mosaic

open access: yesEcological Research, Volume 41, Issue 5, September 2026.
This study investigated how habitat structure gradients are associated with frog species richness and occupancy in a naturally heterogeneous Atlantic Forest mosaic. We found that frog richness and occupancy patterns varied among ecological guilds and were highest in sites associated with lower values of the habitat structure gradient, which also ...

Species Extirpation and Colonization Reveal Mixed Homogenization and Differentiation Across Terrestrial Taxa After One of the World's Largest Tailings Dam Failures

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Fundão tailings‐dam failure (2015)—study area and impact gradient. Regional maps locate the Rio Doce Basin in southeastern Brazil and the Fundão dam (red cross), with the black rectangle marking the extent of the main map. The main map follows the downstream tailings pathway along the river corridor (plume highlight).

The role of precipitation and host assemblage composition in shaping bat–bat fly network structure

open access: yesEcosphere, Volume 17, Issue 8, August 2026.
Abstract Climatic seasonality plays an important role in shaping ecological interactions, including those between bats and their ectoparasitic bat flies. Although previous studies have acknowledged the influence of climate on the structure of bat–bat fly interaction networks, the existence of biogeographical patterns driven by climatic seasonality ...

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.
