研究领域

1) Processes through which environmental factors affect reproduction – Our aim is to understand how interactions between an animal and its environment (nutrition, pheromones, photoperiod, stressors) determine its reproductive strategy, then make use of that knowledge to develop 'clean, green and ethical' systems of animal management' 2) Reproductive biology and technology in ratites (emu, ostrich) – Animal production depends on genetic selection, but the basic biology of ratites (pair-bonding, male egg incubation, seasonal breeding) is a major limitation. We are studying reproductive physiology and behaviour and developing artificial insemination.
