Thu 23 Jan 2025. Electric Ecology; How Invertebrates Capitalise on Static Electricity
Dr Sam J. England | Museum für Naturkunde.
The Brad Ashby Memorial Lecture
Most terrestrial animals naturally accumulate electrostatic charges, meaning that they will generate electric forces that interact with other charges in their environment, including those on or within other organisms. Join us on a journey through the often unnoticed ecological role of static electricity in nature. Dr Sam England will discuss how electrostatic forces attract pollen onto butterflies and moths, allowing them to be more efficient pollinators; how the charge of tick hosts like cows, dogs, and humans, pulls ticks across air gaps to make them better parasites; and finally how many insects can detect static electricity, and use it to sense the approach of their predators.
