Moth Communities Reveal High Stability Despite Ongoing Compositional Shifts Over Five Years Following Hurricane Disturbance

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We examined the temporal dynamics and ecological stability of tropical forest moth communities using a unique dataset spanning 6 months before and up to 5 years after two extreme hurricanes. While abundance and richness recovered within 2 years, species composition continued to shift, indicating ongoing reassembly with a directional trajectory toward ...

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 ...

Dielectric‐Doped 2D Tellurium Diodes for Zero‐Bias Radio Frequency Power Detection

Advanced Electronic Materials, Volume 10, Issue 11, November 2024.
This work presents a 2D Tellurium (Te)‐based radio frequency (RF) diode that exploits a dielectric doping technique to enhance its performance as a power detector. The atomic layer deposited Al2O3 is used to n‐type dope the Te flake to engineer the rectifying Schottky contact.

Differential responses of community‐level functional traits to mid‐ and late‐season experimental drought in a temperate grassland

Journal of Ecology, Volume 112, Issue 10, Page 2292-2306, October 2024.
These findings suggest that functional trait composition of grassland communities may shift under climate change‐induced drought, depending on the growing season timings. Trait‐based attempts to predict ecosystem functioning must account for such temporal variation in community trait values.

Fast changes in seasonal forest communities due to soil moisture increase after damming

Revista de Biología Tropical, 2013
Local changes caused by dams can have drastic consequences for ecosystems, not only because they change the water regime but also the modification on lakeshore areas.
