Food habits of mute swans in the Chesapeake Bay
Unlike the tundra swan (Cygnus columbianus) that migrate to the Bay for the winter, the mute swan (Cygnus olor) is a year long resident and therefore has raised concerns among research managers over reports of conflicts with nesting native water birds and the consumption of submerged aquatic vegetation (SAV). Although data on the reduction of SAV by nesting mute swans and their offspring during t

Hydrologic processes in deep vadose zones in interdrainage arid environments
A unifying theory for the hydrology of desert vadose zones is particularly timely considering the rising population and water stresses in arid and semiarid regions. Conventional models cannot reconcile the apparent discrepancy between upward flow indicated by hydraulic gradient data and downward flow suggested by environmental tracer data in deep vadose zone profiles. A conceptual model described

Invasive herbivory: resident Canada geese and the decline of wild rice along the tidal Patuxent River
While concern grows over the increasing numbers of exotic mute swans (Cygnus olor) on the Chesapeake Bay, less attention seems to be given to the highly familiar and native Canada goose (Branta canadensis) which has over time developed unprecedented nonmigratory, or resident, populations. Although nuisance flocks of Canada geese have been well advertised at city parks, athletic fields, and golf co
