Going silent? Evidence for independent losses of acoustic communication in tree crickets (Insecta, Orthoptera, Grylloidea, Oecanthidae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Our ancestral state reconstruction in tree crickets reveals multiple independent and irreversible losses of sound‐producing and ‐receiving structures, supporting the convergent evolution of the silent phenotype. We demonstrate strong evolutionary integration between forewings and tympana, although the discovery of ‘silent listeners′ and ‘deaf singers ...

Antioxidant and Cytotoxic Properties of Piper spp. Volatile Oils That Inhibit Pathogenic Microorganisms

open access: yesFlavour and Fragrance Journal, Volume 41, Issue 4, Page 935-942, July 2026.
The samples were fungicidal against Candida, with MICs ranging from 62.5 to 250 μg/mL, and fungistatic against Penicillium adametzii, Aspergillus flavus and A. niger, with MICs of 1000 μg/mL. The volatile oils of Piper aduncum and Piper marginatum reduced the viability of MDA‐MB231 cells.
