  • Animal geographies II: methods 

    Buller, HJ (Sage, 2014)
    Animal geographies challenge not only the place and placing of the human and the animal but, critically, the methods we use to engage with both in relation. This second review considers the various methodological implications ...
  • Animal Geographies III: Ethics 

    Buller, HJ (SAGE Publications, 2015-04-19)
    There is no animal geography without ethics. The very coupling of the words gives rise to an ethical endeavor; an acceptance that animals have a geography, a making visible of animals within our human geography and ...
  • Animal Research, the 3Rs, and the “internet of things”: Opportunities and Oversight in International Pharmaceutical Development 

    Niemi, S; Davies, GF (Oxford University Press (OUP) for Institute for Laboratory Animal Research (ILAR), 2016)
