Backwell Lab - Behavioural ecology of fiddler crabs

Backwell lab members

We study the behaviour of fiddler crabs in their natural environment (tropical mangrove forests) in Darwin. In the past five years, we have also worked in Mozambique, Zanzibar and Central America. We work on the social behaviour of about 10 species of fiddlers, looking at their mating systems, deceptive signalling, fighting behaviour and co-operative behaviour. We are also looking at the effects of climate change on the behaviour of fiddlers.
