Hydrologic processes in deep vadose zones in interdrainage arid environments 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...

Invasive herbivory: resident Canada geese and the decline of wild rice along the tidal Patuxent River 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...

Modeling survival and movement of resident giant Canada goose populations in the Atlantic flyway Modeling survival and movement of resident giant Canada goose populations in the Atlantic flyway
Distribution of resident giant Canada geese (Branta canadensis maxima) has changed markedly in the Atlantic Flyway in recent decades. This change may be related to habitat variation or to changes in hunting regulations. We attempt to assess impacts of hunting regulations on survival, movement, and harvest rate of Canada goose populations from Maine to South Carolina. During 15 June-31...

Molecular methods for discriminating taxa, monitoring species, and assessing fungal diversity Molecular methods for discriminating taxa, monitoring species, and assessing fungal diversity
Exiting new molecular approaches that allow investigators to assess fungal biodiversity directly are being developed. These approaches are still in their infancies, but they are developing rapidly. The following papers provide an introduction to this burgeoning field of study: Bohannan and Hughes (2003), Cooksey (1997), Jumpponen (2003), Landeweert et al. (2003), Nikolchva et al. (2003)...

Mute swans: Natural (?) environmental indicators Mute swans: Natural (?) environmental indicators
The rapid expansion of the Chesapeake Bay's population of feral mute swans (Cygnus olar), coupled with a dramatic Bay-wide decline in submerged aquatic vegetation (SAV), has fueled much of the current debate surrounding the need for a management plan to protect the aquatic food resources that are critical to many species native to the Bay. Crucial to this decision process is a sound...
