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 ...

Ecology and Evolution, Volume 7, Issue 1, Page 419-428, January 2017., 2017 The matched filter hypothesis is an important principle in evolutionary biology. Here, we show an important exception for a frog species that inhabits a noisy streamside environment. In this species, the receiver's peripheral auditory frequency sensitivity is mismatched completely with male acoustic signals, which are higher in frequency than those of ...

Ecosphere, Volume 16, Issue 5, May 2025.Abstract Disturbances play a central role in shaping biodiversity, influencing both community structure and ecosystem function. The responses of biodiversity to disturbance are inherently multidimensional, often leading to shifts in taxonomic composition, functional traits, and evolutionary dynamics within biological communities.
