Seasonal variation in the phenol content of Eugenia uniflora L. leaves Variação sazonal nos teores de fenóis de folhas de Eugenia uniflora L

Revista Brasileira de Plantas Medicinais, 2011
Hydrolysable tannins, total phenols and flavonoids in Eugenia uniflora leaves were monthly analysed for one year. The results were correlated with climate conditions (rainfall, humidity, cloudiness and mean temperature) through chemometric methods ...

Cooperative human signals to honeyguides form local dialects

People and Nature, Volume 8, Issue 3, Page 682-694, March 2026.
Abstract Human language enables the exchange of complex information and precise instructions for collaborative planning and action. It rapidly evolves through social learning, generating diverse cultural communication signals used not only with other humans, but also with domesticated animals bred or trained to respond.

The frequency and importance of polyploidy in tropical rainforest tree radiations

New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

Urban rendezvous: Spatiotemporal overlap is more important than abundance and trait matching for urban plant–pollinator interactions

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our study shows that the generalized structure of urban plant–pollinator interactions is mirrored in the mechanisms that shape them, as interactions are governed primarily by less restrictive drivers such as abundance and spatiotemporal overlap rather than by trait matching.

Competitor Richness Outweighs Climate and Land Cover in Explaining Abundance Variation of a Neotropical Fruit Bat

Austral Ecology, Volume 51, Issue 1, January 2026.
ABSTRACT Understanding which processes regulate spatial variation in species abundance across their ranges is key in ecology. Species abundances may be affected by several factors, such as climate, elevation, land cover, species interactions and habitat protection status. However, few studies have focused on these effects synergistically across species

Trait coordination reveals the fast–slow plant economics spectrum along the vertical canopy profile in central Amazonian forests

Functional Ecology, Volume 39, Issue 12, Page 3596-3610, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding how environmental drivers affect tree functioning is essential to improve predictions of tropical forests' response to climate change. While functional traits directly influence tree performance, our understanding of how canopy environments shape their ...
