Leaf development in Xylopia aromatica (Lam) Mart. (Annonaceae): implications for palatability to Stenoma scitiorella Walker 1864 (Lepidoptera: Elachistidae)

Brazilian Journal of Biology
Variations in specific foliar mass and water content, nitrogen, soluble carbohydrates and tannins were studied during the growth and maturation processes of the Xylopia aromatica leaves, to determine the effects of such alterations on the herbivory of ...

Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

Global Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Relação entre heterogeneidade ambiental e distribuição de espécies em uma floresta paludosa no Município de Cristais Paulista, SP, Brasil Floristic composition and relationship between environmental heterogeneity and species distribution in a swamp forest from Cristais Paulista, São Paulo State, Brazil

Acta Botânica Brasílica, 2009
Neste estudo foi caracterizada a composição florística e fitossociológica de uma floresta paludosa no nordeste do Estado de São Paulo, onde variações no padrão de drenagem ocorrem principalmente no sentido perpendicular ao curso d'água, em função da ...

Flowering Asynchrony and Temporal Mate Restriction in Tropical Peat Swamp Forest Trees

Biotropica, Volume 58, Issue 2, March 2026.
Tropical peat swamp forest trees flower asynchronously, restricting mating opportunities between conspecifics. Using an 18‐year dataset from Central Kalimantan, Indonesia, we show that while the same individual trees tend to flower together through time, there is enough turnover in which trees flower contemporaneously that lifetime mate restriction and

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

A New Xylopia (Annonaceae) from Panama

Novon, 1993
Xylopia panamensis sp. nov. is pro- posed based on material from Santa Rita Ridge and El Llano-Carti road formerly referred to Xylopia bocatorena Schery. The new species differs from X. bocatorena by its rounded leaf base, longer in- dument on the bracts and calyx, smaller flowers, fewer seeds per monocarp, and thus shorter mon- ocarps.

Communities with diverse subsistence needs require a variety of functional tree traits

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Malagasy forest users vary the traits that they prefer for different household uses. Accessibility is prioritized for daily uses such as fuelwood, while functional traits are valued for longer‐term uses. Differences between men and women reflect traditional gender roles.

Influence of Aqueous, Ethanolic, and Hydroethanolic Extraction on Phytochemical Content and Cardiometabolic‐Related Bioactivities of Four Cameroonian Spices

BioMed Research International, Volume 2026, Issue 1, 2026.
Background Cameroonian spices are rich in bioactive phenolics with potential applications in functional foods and nutraceuticals. Yet, the influence of solvent polarity on phytochemical extraction and the resulting multifunctional in vitro activities remains insufficiently characterized.
