Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline

Insect Conservation and Diversity, EarlyView.

Projected Climate‐Suitable Area for Apis mellifera (Apidae) and Its Spatial Overlap With a Mining Tailings Footprint in South‐East Brazil

Journal of Applied Entomology, EarlyView.
ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).
