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

Journal 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).

Plant functional traits shape the provision of ecosystem services to Indigenous communities in western Amazonia

People and Nature, Volume 7, Issue 12, Page 3313-3329, December 2025.
Abstract Context. Exploring how Indigenous People interact with plants through their functional traits allows us to understand the ecological bases of plant selection. Functional traits can help explain why certain plants are consistently chosen for specific purposes across diverse cultural contexts.

Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches

New Phytologist, Volume 248, Issue 1, Page 370-388, October 2025.
Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...
