Different Patterns of Pd-Promoted C-H Bond Activation in (Z)-4-Hetarylidene-5(4H)-oxazolones and Consequences in Photophysical Properties

open access: yesInorganics
This work aims to amplify the fluorescence of (Z)-4-hetarylidene-5(4H)-oxazolones 1 by suppression of the hula-twist non-radiative deactivation pathway by C^N-orthopalladation of the 4-hetarylidene ring.

Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.

Species functional traits affect regional and local dominance across western Amazonian forests

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A

Inverse effects of soil moisture and litter quality on litter decomposition along a gradient from hyper‐arid to temperate climate

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
We hypothesized that litter decomposition (H1) and litter quality (H2) increase with increasing soil humidity, therefore litter from the wetter sites to have the highest litter quality and decompose fastest in each site, and fastest on the wet end of the gradient (H3).
