Always deeply interested in mammal ecology, John joined the Mammal Society at school (1961) and later The British Ecological Society and The American Society of Mammalogists. His Zoology BSc (1967) led to a DPhil on experimental small mammal population ecology (Oxford, 1971). Starting in 1972, teaching Cambridge undergraduates dovetailed with mammal research and extramural lecturing/field courses. In retirement he supervises Cambridge undergraduate Zoology dissertations and lectures in Part II Zoology (Holocene and modern biodiversity of British mammals).
As an authority on British mammals he has co-authored species reviews of The Bank vole and The Wood mouse for The Mammal Society’s Handbook of British Mammals (1977, 1991, 2008) and co-authored Live Trapping Small Mammals. A Practical Guide (1982, 1990, 1994, 2006, 2019, in press). He served on the Editorial Board of Mammal Review (1975-2010) and co-edited/organized a Symposium on The Ecology of Woodland Rodents in 1985. He has published two books: Mammals. Their reproductive biology and population ecology (1987) and Mice and Voles (1993). In 1980 he joined MAFF’s 10-year pesticide study, The Boxworth Project: The Environmental Effects of Pesticides in the Cereal Ecosystem, HMSO (1993), publishing on the effects of methiocarb molluscicide pellets on wood mouse populations and the diet of shrews. He has produced 60 mammal research papers, books and reviews. He was awarded The Mammal Society’s Silver Medal in 1986 for his contributions to the Society and to mammal ecology.
John served as Wolfson’s Undergraduate Admissions Tutor (Sciences/Medicine) from 2000-2008. With then-Senior Tutor Joan Whitehead he helped develop structured interviews and numerical assessment for the Graduate Course in Medicine, now offered to increased numbers by mature colleges. As Emeritus Fellows’ External Events (Joint) Secretary (2014-2018), he organized many visits, including the annual North Norfolk coastal walk, Woolsthorpe Manor (Sir Isaac Newton’s birthplace) and Harlaxton Manor among others.
