  • Disease invasion dynamics : brucellosis and tuberculosis in African buffalo (Syncerus caffer)

    Creator:
    Gorsich, Erin E.
    Abstract:
    Emerging infectious diseases in wild animals threaten global biodiversity as well as domestic animal and human health. Their unprecedented increase in conjunction with anthropogenically induced range shifts of endemic pathogens exposes hosts to novel parasite combinations, lending urgency to research on disease dynamics in wildlife systems. In natural populations, hosts...

  • Emergent Properties of Animal Social Networks: Five Stories in Five Systems

    Creator:
    Devan-Song, E. Anne
    Abstract:
    Animals aggregate and interact in nonuniform and nonrandom patterns, which lead to group level characteristics that have important evolutionary and ecological consequences. Network analysis provides a useful conceptual framework for linking animal interactions at all scales from dyads to communities, to populations and ecosystems. Despite exciting theoretical and applied advances...

  • Investigating variation in immunity and infection risk in wild ungulates

    Creator:
    Dugovich, Brian S.
    Abstract:
    In the midst of the sixth mass extinction, understanding wildlife disease spillover is critical to maintaining protected wildlife areas. Studying ecoimmunology and wildlife disease ecology helps to understand immune and disease traits in an ecological context, which is invaluable in preventing pathogen spillover between livestock and wildlife. To investigate this...

  • Individual Host to Population Scale Dynamics of Parasite Assemblages in African Buffalo of Kruger National Park, South Africa

    Creator:
    Glidden, Caroline K.
    Abstract:
    The last century has experienced a marked increase in emerging infectious disease (EID, hereafter) – jeopardizing human, domestic animal, and wildlife health. EIDs are commonly associated with spillover from one host species into a novel host species, with many destructive diseases, for both livestock and wildlife, emerging at the wildlife-livestock...

  • Rift Valley fever in African buffalo (Syncerus caffer) : basic epidemiology and the role of bovine tuberculosis coinfection

    Creator:
    Beechler, Brianna
    Abstract:
    Rift Valley fever (RVF) is a mosquito-borne zoonotic viral disease native to the African continent. Outbreaks tend to occur in the wet seasons, and can affect numerous mammalian species including African buffalo. It is debated how the virus survives the inter-epidemic period when it is not detected in mammalian populations,...
