Dick Neal is Professor Emeritus at the University of Saskatchewan, Canada, having taught undergraduate ecology for almost forty years. His thesis on Ugandan rodents was conducted at the Nuffield Unit of Tropical Ecology in Uganda, and he continued this research on the breeding of African rodents with sabbaticals in National Parks in Kenya (1974-5) and Zimbabwe, (1987-88, 1990). Other research areas have included the impacts of uranium mine effluent on aquatic ecosystems; effects on the structure and function of plankton communities; and the bioremediation of contaminated pits.
