Dr Miranda Dyson
Miranda is a Senior Lecturer in Biology at The Open University.
Her research interests are in animal behaviour and communication. She has worked on several species of frogs (in South Africa, America and England) looking at reproductive behaviour. During the breeding season male frogs use vocalizations to attract females and females use male calls to choose among potential mating partners. Her work has aimed at determining what aspects of male vocal signals females attend to when choosing a mate and also how males compete with each other for access to females.
Miranda has also worked on fiddler crabs both in South Africa and Australia. Unlike frogs, fiddler crabs communicate mainly through visual cues. Males have an often brightly coloured enlarged claw which they use to attract females (by waving at them) and to fight with other males. Her interest is figuring out how females choose among males using these visual signals (male claw colour and wave characteristics).
