Status:
Completed
Objectives:
(1) Measure lead exposure on 1xbet online casino .
(2) Model the population effect of lead exposure on 1xbet online casino .
(3) Determine effect of coastal marsh management practices on population demography of 1xbet online casino .
Progress and Results:
The black-necked stilt has been studied extensively in the western United States, but its habitat requirements and breeding ecology are poorly delineated elsewhere. In western North America, black-necked stilts exist in dense populations, often clustered around salt evaporation ponds and managed wetlands, while black-necked stilts in the Southeast are putatively more broadly distributed in coastal marsh habitats. These regional habitat differences may promote variation in metapopulation structure, nest-site selection, reproductive success, and habitat and space use, none of which are well described in coastal 1xbet online casino . Moreover, historic waterfowl harvest sites along the 1xbet online casino coast have extensive lead deposition from spent shot. Although lead shot ingestion has been documented in black-necked stilts no data exist on blood lead concentrations or potential effects on survival, nest success, and other vital. This research has been designed to quantify black-necked stilt blood lead levels, habitat use, nest-site selection, and nest success on the upper 1xbet online casino coast.
