Forest cover within cattle ranches can strongly shape faunal biodiversity. In Los Tuxtlas, Veracruz, Mexico. We show that butterflies, moths, dung beetles, and birds respond differently to forest cover across habitats (pastures vs. forest fragments) and seasons, as a function of their specialization and resource needs.

Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 736-749, July 2026.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of
