What to know about Machine Learning in Ecology

Researchers at the University of California, Riverside, have used a machine learning model to identify chemical compounds that repel honey bees. The study, published in eLife, suggests these repellents could protect bees from pesticide exposure and assist in managing bee-human conflicts.

What happened

Machine learning helps identify chemicals that repel honey bees from pesticides Gaby Clark Scientific Editor Robert Egan Senior Editor In a win for pollinator conservation, researchers at the University of California, Riverside, have developed a machine…

Why it matters

The research offers a potential solution to one of agriculture's most urgent ecological challenges: the ongoing decline in honey bee populations, driven in part by pesticide exposure.

Common ground

The interdisciplinary team led by Anandasankar Ray, a professor of molecular, cell and systems biology and an expert on insect olfactory behavior, tackled a central obstacle to altering pollinator behavior to protect them: the complexity of the honey bee…
