  • Pfiesteria-related educational products and information resources available to the public, health officials, and researchers 

    Kleindinst, Judith L.; Anderson, Donald M. (National Institute of Environmental Health Sciences, 2001-10)

  • Phenological mismatch strongly affects individual fitness but not population demography in a woodland passerine 

    Reed, Thomas E.; Jenouvrier, Stephanie; Visser, Marcel E. (2012-02-20)
    Populations are shifting their phenology in response to climate change, but these shifts are often asynchronous among interacting species. Resulting phenological mismatches can drive simultaneous changes in natural ...
