Trait‐mediated effects driven by an invasive herbivore alter functionally diverse plant–frugivore interactions

Functional Ecology, Volume 40, Issue 1, Page 216-228, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits play a fundamental role in mediating plant‐frugivore interactions, shaping seed dispersal dynamics. Given the complexity of multi‐species interactions, these traits and, consequently, plant‐frugivore interactions can be indirectly influenced by third‐party ...

Wettability of Amino Acid-Functionalized PSMA Electrospun Fibers for the Modulated Release of Active Agents and Its Effect on Their Bioactivity

Pharmaceutics, 2023
The ideal treatment for chronic wounds is based on the use of bioactive dressings capable of releasing active agents. However, the control of the rate at which these active agents are released is still a challenge.

Gipsgärten: Selbstorganisierte röhrenförmige Strukturen aus Calciumsulfat mit Relevanz für die Suche nach außerirdischem Leben

Angewandte Chemie, Volume 137, Issue 48, November 24, 2025.
Chemische Gärten sind selbstorganisierte abiotische Strukturen mit „lebensähnlichen” Formen. Hier zeigen wir, dass solche Prozesse auch nach Zugabe konzentrierter Sulfatlösungen zu festen Calciumsalzen ablaufen und sogenannte Gipsgärten ergeben. Die dafür nötigen Bedingungen sind weitgehend kompatibel mit den geochemischen Verhältnissen auf dem frühen ...

Astrocaryum ulei (Arecaceae) newly discovered in Peru

Revista Peruana de Biología, 2011
Astrocaryum ulei, previously known from Brazil and Bolivia, is here reported from Madre de Dios in Peru. Based on the new material collected it has been possible to write an amended description of this species, which is presented here.

Gypsum Gardens: Self‐Assembled Tubular Structures of Calcium Sulfate with Relevance for the Detection of Extraterrestrial Life

Angewandte Chemie International Edition, Volume 64, Issue 48, November 24, 2025.
Chemical gardens are self‐assembled architectures with “life‐like” morphologies that form in the absence of any biological activity. Here we show that such structures can also be obtained by contacting reservoirs of calcium and sulfate ions, under conditions that plausibly emulate those prevailing on early Mars.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

Journal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

Genomics and morphometry of herbarium specimens elucidate the origin of the Cape Verde date palm (Phoenix atlantica A.Chev.) and highlight its agronomic potential

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1358-1371, September 2025.
As climate change accelerates, breeding resilient crops is urgent. The date palm (Phoenix dactylifera L.), a crucial 18 billion USD fruit crop, underpins North African and West Asian oasis agroecosystems. This study investigates the genetics and morphology of its closest wild relative, the endemic and endangered Cape Verde date palm (Phoenix atlantica ...

Wood density variation across an Andes‐to‐Amazon elevational gradient

Journal of Ecology, Volume 113, Issue 9, Page 2370-2385, September 2025.
We study how wood density varies along a 3500‐m elevational gradient, spanning from the Andean tree line to the Amazon basin. Our results reveal that wood density decreases from low to mid‐elevations, then increases toward the tree line. These patterns underscore the influence of species composition, life forms such as tree ferns, and local ...

La palmera de coateco

Botanical Sciences, 1948
Entre las palmeras silvestres que se encuentran a lo largo de la Costa Chica del Estado de Oaxaca, principalmente en el Distrito de Juriquilla y a unos 400 metros sobre el nivel del mar, se encuentra una conocida regionalmente como "Palma de Coateco", cuyo tallo está cubierto de espinas amarillas, y que tal vez pudiera ser la Acanthorrhiza Mocinni (H ...
