Nutrients or resin? – The relationship between resin and food foraging in stingless bees [PDF]

Ecology and Evolution, Volume 14, Issue 2, February 2024.
We analyzed the role of resin intake on the foraging behavior and resource intake of tropical stingless bees in Ecuador. We show that stingless bee species with a large workforce devoted to collecting resin were overall more active, and foraged on pollen from slightly different spectra of plants, suggesting that species engaging in high resin ...

Compost legacy effects in active roadside restoration: Medium‐term shifts in plant succession

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Roadside restoration experiment established on volcanic tephra following road construction in Andean Patagonia. A single application of municipal (MC) or biosolids (BC) compost rapidly increased plant cover compared with untreated controls (C) but led to distinct, exotic‐dominated plant communities over 6 years.

Salty suitors: High larval sodium intake reduces adult lifespan and influences reproductive behaviour in a lepidopteran herbivore

Ecological Entomology, Volume 50, Issue 5, Page 886-898, October 2025.
Low‐sodium females took significantly longer to start mating than high‐sodium females, but no pairings differed in the duration of copulation. Reproductive outputs, measured by number of clutches, hatching young, adult offspring and pupation time, did not differ across parental sodium pairings.

Descrição e fatores modeladores da dieta e ecologia da alimentação de girinos neotropicais: Um estudo de caso e uma revisão abrangente

Austral Ecology, Volume 49, Issue 1, January 2024.
Resumo Os girinos são componentes importantes de muitas teias alimentares aquáticas, pois influenciam as populações em outros níveis tróficos e, consequentemente, a transferência de energia entre os ecossistemas aquáticos e terrestres. O que os girinos consomem é um fator chave para suas funções ecológicas. As assembleias de anuros neotropicais incluem
