open access: yesConservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

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

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
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
