EFFECTS OF SEDIMENTATION ON PLAYA WETLAND VOLUME
Over 50% of the wetlands in the conterminous United States have been lost; however, few studies have investigated the more insidious effects of sedimentation on wetland volume. We examined theExpand

Assessment of the effects of farming and conservation programs on pesticide deposition in high plains wetlands.
We examined pesticide contamination in sediments from depressional playa wetlands embedded in the three dominant land-use types in the western High Plains and Rainwater Basin of the United StatesExpand

Floral Diversity in Relation to Playa Wetland Area and Watershed Disturbance
There are 25,000-30,000 playa wetlands in the intensively cultivated Southern Great Plains of the United States. Knowledge of area and watershed influences on wetland flora are needed to guide theirExpand

Interactive effects between nest microclimate and nest vegetation structure confirm microclimate thresholds for Lesser Prairie-Chicken nest survival
ABSTRACT The range of Lesser Prairie-Chickens (Tympanuchus pallidicinctus) spans 4 unique ecoregions along 2 distinct environmental gradients. The Sand Shinnery Oak Prairie ecoregion of the SouthernExpand
