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.

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

“Humanizar”: aprendizajes sobre alteridad, salud y futuro en una experiencia de investigación compartida

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT The visit to Bogotá of a fééeneminaa (Muinane) friend, Célimo Nejedeka Jifichíu, and in particular, his work in researching and transmitting traditional health knowledge, offer the pretext to navigate the relationship between elements that at first glance seem distant from each other: indigenous imaginaries about otherness, their visions of ...

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

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2946-2965, June 2026.
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 ...

Fermentation techniques for protein enrichment of cassava peel

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4384-4393, May 2026.
Abstract BACKGROUND The use of agro‐industrial by‐products such as unconventional feeds in animal production is an alternative for reducing the high costs associated with conventional feeds. The present study aimed to evaluate the effect of aeration, pH adjustment, the use of yeast (Saccharomyces cerevisiae) and the amount of urea on the enrichment of ...
