Lord Krebs
Brian Lewis Krebs, Baron Krebs (born 15 March 1945) is a British zoology and behavioural ecology academic, science administrator, and crossbench life peer in the House of Lords. He is noted for empirical work on songbird foraging and predator–prey behaviour, leadership of research councils, and contributions to UK science policy and public understanding of science.
Krebs was born in Edinburgh and educated at local schools before attending University of Oxford where he read Zoology and later completed a DPhil focusing on behavioural ecology influenced by figures associated with the Oxford University Museum of Natural History and the legacy of Niko Tinbergen. His formative training connected him to laboratories and field sites used by researchers from Cambridge University and the British Trust for Ornithology, exposing him to comparative work on song thrush and great tit feeding strategies. During this period he engaged with contemporaries from University of Edinburgh and drew on theoretical approaches developed alongside scholars at the Centre for Ecology & Hydrology.
Krebs built an academic career rooted in experimental studies of foraging theory, predation, and information use by animals, publishing influential empirical papers that cited and extended models by theorists from Princeton University and University of Chicago. He held posts at University of York where he developed collaborative programs with researchers from Max Planck Society institutes and organised fieldwork at long-standing sites associated with RSPB reserves and the British Ecological Society. His textbook-style syntheses and review articles placed him in dialogue with authors from Cambridge University Press and editors at journals such as Nature and Proceedings of the Royal Society B, and he served on editorial boards alongside scientists from Smithsonian Institution and University of California, Berkeley.
Krebs’s lab combined observational studies with controlled experiments, integrating methods promoted by researchers at Imperial College London and incorporating statistical approaches pioneered by groups at University of Aberdeen and St Andrews. He supervised doctoral students who later joined faculties at University of Glasgow, University of Sheffield, and University of Manchester and contributed to multicentre projects funded by Natural Environment Research Council and European programmes linked to European Molecular Biology Organization. His work influenced conservation practice by informing guidance used by Joint Nature Conservation Committee and practitioners within the Wildlife Trusts network.
Beyond the laboratory, Krebs moved into science administration and public service, chairing the Natural Environment Research Council and advising UK Government departments on research priorities. He led national reviews and reports that addressed evidence use in policy-making, interacting with ministers from Department for Environment, Food and Rural Affairs and officials at Cabinet Office and the Royal Society. Elevated to the House of Lords as a crossbench life peer, he contributed to debates on research funding, biosecurity, and environmental regulation alongside peers from House of Commons select committees, and engaged with inquiries by the Science and Technology Select Committee.
His public-facing activities included chairing panels and reviews for organisations such as the Wellcome Trust and the Nuffield Foundation, delivering lectures at venues linked to Royal Institution and collaborating with science communicators associated with BBC natural history programming. He advised international bodies and participated in workshops alongside representatives from the United Nations Environment Programme and the Intergovernmental Panel on Climate Change.
Krebs’s contributions earned election as a Fellow of the Royal Society and appointments including Commander of the Order of the British Empire and a knighthood, followed by a life peerage in the Peerage of the United Kingdom. He received honorary degrees from universities such as University of York and University of Edinburgh and medals bestowed by bodies like the Zoological Society of London and the British Ecological Society. His service to science and policy was recognised by awards and honorary fellowships from institutions including Royal Society of Edinburgh and the Academy of Medical Sciences.
Krebs married and raised a family while maintaining an active research and administrative schedule; his relatives have been associated with academic and public-service roles at institutions such as University College London and local civic organisations in Oxford. His intellectual legacy is reflected in the persistence of his empirical findings within curricula at departments of Zoology and Ecology across UK universities and in policy frameworks influenced by his reviews used by the Natural History Museum and conservation NGOs. His books and review essays continue to be cited by researchers at centres including ETH Zurich, University of British Columbia, and CSIRO, and his career serves as a model for integrating academic research with public engagement and evidence-informed policy.
