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

open access: yesNew Phytologist, EarlyView.
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 ...

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 ...

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

open access: yesEcological Entomology, Volume 51, Issue 3, Page 502-516, June 2026.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

open access: yesEcological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

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
