Josephine M. Pemberton is a British evolutionary biologist.

Pemberton studied zoology at the University of Oxford and received his doctorate in 1983 with Robert H. Smith at the University of Reading with a dissertation on the population genetics of fallow deer . She was a post-doctoral student at University College London and Cambridge University . She was an Advanced Fellow of the Biotechnology and Biological Sciences Research Council (BBSRC) in Cambridge and Edinburgh and from 1994 Lecturer at the University of Edinburgh , where she is Professor of Molecular Ecology.

She explores causes of fitness differences in individuals and relationships (analysis of ancestry, reconstruction of pedigrees), phenotype development, suppression of inbreeding, resistance to parasites and quantitative trait locus in natural free-living (wild) populations of animals, with them in particular long-term studies of soay sheep on the island of St. Kilda (Scotland) and red deer on the Hebridean island of Rùm . She found that dominant females in red deer have more male offspring, but that the ratio is balanced out again by environmental stress (more rain in winter, higher population density). In her dissertation, she found a notable lack of polymorphism in fallow deer populations in England and Wales , which she attributed to a domestication period in the Meso- or Neolithic period. In 2017, she investigated genetic evidence of environmental impact in inbreeding suppression in Soapy sheep. Previously, an influence of unfavorable environmental conditions (such as high population density) on inbreeding suppression had been proven experimentally, but this was rarely found in studies of wild animal populations. Pemberton found the influence of population density (environment) in the sense of inbreeding suppression in 6 of 9 lineages, but only 2 of them were statistically significant.

In 2011 she received the Molecular Ecology Prize and in 2018 the Darwin Wallace Medal . She is a Fellow of the Royal Society (2017) and a member of the European Molecular Biology Organization (EMBO) since 2014 .
