Ducks and other waterfowl in the U.S. are valued and enjoyed by millions of birdwatchers, artists, photographers and citizens for their beauty and appeal. Waterfowl also provide game for hunters throughout the country and act as an important source of revenue for states and local communities. Loss of habitat and migration corridors due to land use changes and changes in climate threaten these birds, however more scientific information is needed to understand these processes. This project used available annual surveys of duck counts, along with data on the location and availability of ponds and temperature and precipitation patterns, to model where across the continental landscape waterfowl were present and if their...

Populations of lesser prairie-chickens are proposed for listing as threatened or endangered. Lesserprairie-chickens require relatively intact, large grassland dominated habitats for population persistence. Successful conservation efforts require knowledge of potential landscape thresholds and grassland patch configuration affecting lesser prairie-chicken populations. We will use existing population survey, lek location, and data from >700 previously marked lesser prairie-chickens to determine the potential for the presences of large-scale landcover thresholds that influence occupancy and persistence of lesser prairie-chickens as well as testing effects of gradients of grassland composition and configuration within...
