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

open access: yesFunctional 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

open access: yesPharmaceutics, 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

open access: yesAngewandte 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 ...

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

open access: yesAngewandte 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.

A Proposal for a Modified Moller-Plesset Perturbation Theory

open access: yes, 2004
A modified version of the Moller-Plesset approach for obtaining the correlation energy associated to a Hartree-Fock ground state is proposed. The method is tested in a model of interacting fermions that allows for an exact solution.

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

open access: yesJournal 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
