Extreme weather events, including hurricanes and tropical cyclones, could be increasing aggressive behaviour among spiders, according to researchers at McMaster University. Volatility such as falling trees and loose debris can force spiders to gather resources more efficiently to increase the chance of survival in difficult conditions. Recent studies on spiders living in regions prone to dangerous weather situations shows that colonies in volatile environments with more aggressive foraging responses had more young spiders survive into colonies. With extreme weather events on the rise due to climate change, this could influence spider behaviour worldwide over time.
