Professor Brian Moss retired from the University of Liverpool following a career in Africa, the USA and the UK. He was awarded medals by the International Society of Limnology, of which he was President from 2007 to 2013, and the Chartered Institute of Ecology and Environmental Management. He was given the International Institute of Ecology Prize for Excellence in Ecology in 2009 and the book written for that prize, Liberation Ecology, received the British Ecological Society's Marsh Book of the Year Award in 2013.
