Successful recovery of native plants post‐invasive removal in forest understories is driven by native community features

open access: yesEcological Applications, Volume 35, Issue 2, March 2025.
Abstract Temperate forest understories hold the majority of the plant diversity present in these ecosystems and play an essential role in the recruitment and establishment of native trees. However, the long‐term persistence of diverse and functional forest understories is threatened by the impacts of invasive plants.

Plant and frugivore species characteristics drive frugivore contributions to seed dispersal effectiveness in a hyperdiverse community

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 238-253, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal by frugivores is a crucial step of the life cycle of most plants, influencing plant population and community dynamics. Although very important for most ecosystems, we are just beginning to understand which are the mechanisms driving frugivore‐mediated ...

Macauba (Acrocomia aculeata) pulp oil reduces fat accumulation and enhances the lifespan of Caenorhabditis elegans at low temperatures via fat‐1‐ and fat‐7‐dependent pathway

open access: yesJournal of Food Science, Volume 89, Issue 8, Page 5101-5112, August 2024.
Abstract Macauba (Acrocomia aculeata) is a Brazilian palm tree whose oil in the pulp is rich in oleic acid and carotenoids. However, its physiological function remains unknown. This study aimed to investigate the effects of macauba pulp oil (MPO) on the metabolic link between lipid metabolism and lifespan using Caenorhabditis elegans (C. elegans).
