Experimental Infection of Bats with Geomyces destructans Causes White-nose Syndrome

White-nose syndrome (WNS) has caused recent catastrophic declines among multiple species of bats in eastern North America1, 2. The disease’s name derives from a visually apparent white growth of the newly discovered fungus Geomyces destructans on the skin (including the muzzle) of hibernating bats1, 3. Colonization of skin by this fungus is associated with characteristic cutaneous lesions that are the only consistent pathological finding related to WNS4. However, the role of G. destructans in WNS remains controversial because evidence to implicate the fungus as the primary cause of this disease is lacking. The debate is fuelled, in part, by the assumption that fungal infections in mammals are most commonly associated with immune system dysfunction5, 6, 7. Additionally, the recent discovery that G. destructans commonly colonizes the skin of bats of Europe, where no unusual bat mortality events have been reported8, 9, 10, has generated further speculation that the fungus is an opportunistic pathogen and that other unidentified factors are the primary cause of WNS11, 12. Here we demonstrate that exposure of healthy little brown bats (Myotis lucifugus) to pure cultures of G. destructans causes WNS. Live G. destructans was subsequently cultured from diseased bats, successfully fulfilling established criteria for the determination ofG. destructans as a primary pathogen13. We also confirmed that WNS can be transmitted from infected bats to healthy bats through direct contact. Our results provide the first direct evidence that G. destructans is the causal agent of WNS and that the recent emergence of WNS in North America may represent translocation of the fungus to a region with a naive population of animals8. Demonstration of causality is an instrumental step in elucidating the pathogenesis14 and epidemiology15 of WNS and in guiding management actions to preserve bat populations against the novel threat posed by this devastating infectious disease.

Expanding Women's Worlds?: Development, Gender, and Environment in Rural Morocco

This honors thesis is an anthropological exploration of women's cooperatives in two regions of rural Morocco. Specifically, I am interested in how contemporary development projects such as the cooperative are understood by the peoples of these regions. By conducting first-hand ethnographic research among women's cooperatives in two drastically different environments of rural Morocco, I gain further insight into the roles that culture and geography play in determining the 'success' of cooperatives inlocal communities. In using the term 'success,' I will compare notions of success as used by both Western development organizations as well as local people in Morocco. I examine and analyze the very delicate and complex interaction that occurs between largely Western development agencies and local cultures particularly through the lens of gender. I will also convey the importance of an exchange of cultural practices through development projects rather than the imposition of one cultural system on another. In writing this thesis, I hope to contribute to the growing field of the anthropologyof development, a subset of cultural anthropology that examines international development practices and the economic, social, and political factors that have an impact on the local culture. I examine cooperatives from the perspectives of both the people whoparticipate in them through personal interviews as well as development institutions through an ongoing body of published literature. Focusing on gender implications that such development initiatives have on the rural cultures of Morocco, I argue that gender identities are crucial aspects of local cultures that must be addressed within development practices. On a broader scale, I argue that a deeper knowledge of local cultures is essential if development agencies are to be 'successful' in non-Western cultures.
