Pollution can change wildlife behaviour

With an increasing number of factors affecting the animal behaviour, the field of behavioural toxicology is gaining traction within the environmental sciences.

A team of scientists from the University of Portsmouth has developed new scientific tests to better understand the effects of pollution on wildlife behaviour.

An organism’s behaviour is fundamentally important to their survival through feeding, finding mates and escaping predators. Any chemical which could interfere with these responses has the potential to impact the food chain.

Using small shrimp-like crustaceans called amphipods, which are commonly used to monitor environmental toxicology, the researchers have been designing experiments to best answer the questions.

In previously determining that these animals prefer to swim away from the light (negative phototaxis) and preferably be touching the sides of the tanks (positive thigmotaxis), they first set about asking whether these preferences could be altered by the size and shape of their testing tanks..READ MORE
