  • Aquatic community responses to drought disturbance: experimental manipulations of top predator extinctions and stream drying

    Creator:
    Boersma, Kate S.
    Abstract:
    Although it is generally assumed that the intensifying abiotic environment is the primary effect of drought on aquatic organisms, drought-induced top predator extinctions may be an important underlying mechanism. I used manipulative experiments to disentangle the impacts of drying and top predator extinctions on arid-land aquatic invertebrate communities. I then...

  • Drought, dispersal, and community dynamics in arid-land streams

    Creator:
    Bogan, Michael T.
    Abstract:
    Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; these processes act as filters that reduce the regional species pool down to the observed local community. In...
