Simone Schleper is Assistant Professor at the History Department of Maastricht University. Her recent work deals with the history of animal migration research and the management of migratory species. In particular, she looks at the ways in which animal movement and migration have been negotiated with the growing spatial, economic and industrial expansion by humans. The research discussed in this article was part of the project "Moving Animals", funded by the Dutch Research Council (NWO). Two of her recent case studies concern spatial conflicts between migratory wildebeest and local human communities in the Serengeti National Park in Tanzania, and mitigation efforts to allow for the migration of North American caribou close to the resource-extraction infrastructures of the Trans-Alaska Pipeline System.
