Diseases of Honeybee (Apis mellifera)

open access: yes
Honeybees, important pollinators crucial for ecosystem health, are susceptible to a range of bacterial, fungal, and viral diseases that pose significant threats to their colonies. Bacterial diseases include American Foulbrood (AFB) caused by Paenibacillus larvae and European Foulbrood (EFB) caused by Melissococcus plutonius. AFB results in the death of

Indigenous peoples and local community reports of climate change impacts on biodiversity

open access: yesConservation Biology, EarlyView.
Abstract Climate change impacts on biodiversity have been primarily studied through ecological research methods, largely ignoring other knowledge systems. Indigenous and local knowledge systems include rich observations of changes in biodiversity that can inform climate change adaptation planning and environmental stewardship.

The complex world of honey bee vibrational signaling: A response to Ramsey et al. (2017) [PDF]

open access: yesarXiv
Ramsey et al. report on the characteristics and temporal distribution of an interesting vibrational signal that they term the whooping signal, primarily based upon a long-term study of vibrations recorded by accelerometers placed inside two honey bee (Apis mellifera) colonies, one in France and one in the United Kingdom. The goal of the study, the long-

Pharmacophagy in insects: Ecological and evolutionary perspectives on the non‐nutritional use of plant specialized metabolites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Insects interact with plants not only for nutrition but also to actively seek plant specialized metabolites (PSMs) for chemical defense, reproduction, and self‐medication—a behavior known as pharmacophagy. This review examines how insects across diverse orders acquire PSMs from both food and non‐food plants for non‐nutritional benefits.
