This dataset provides location information and some limited attributes of known and potential ciénegas in the Madrean Archipelago ecoregion and closely surrounding area. This was created using point data and information provided by Dean Hendrickson and Thomas Minckley, combined with potential locations derived from analysis of classified raster land cover images and other specialized datasets. Ciénegas, as defined here, are wetlands in arid and semi-arid regions associated with groundwater or lotic components that ideally result in perennial waters on temporal scales of decades to centuries. Ciénegas are typically located at elevations ranging from 0 to 2000m. Ciénegas are typified by significant differences in...
AVI files documenting raccoon (Procyon lotor) foraging for apple snails (Pomacea maculata) on a water hyacinth mat at Mandalay National Wildlife Refuge. Videos were taken with various models of Moultrie camera traps between January and March 2017.

A generalized yet detailed wetland ecosystem model was calibrated and validated with 3 years’s data from four similarly constructed wetlands in northeastern Illinois, USA. The model was used to explore the role of different wetland structure and function in relation to phosphorus retention, to integrate collected data and provide a better understanding at the ecosystem level about constructed wetlands, and to predict the sediment and phosphorus retentions under different hydrologic conditions. Four submodels — hydrology, primary productivity, sediments, and phosphorus — were included in the model. Phosphorus cycling was reasonably simulated with one set of parameters for a total of 10 wetland-years. The model showed...

Ciénegas, as defined here, are wetlands in arid and semi-arid regions associated with groundwater or lotic components that ideally result in perennial waters on temporal scales of decades to centuries. Ciénegas are typically no lower than 0 m, and higher than 2000 m, rarely lower but sometimes higher elevation localities occur. Ciénegas are typified by significant differences in flora and fauna relative to the greater terrestrial conditions in the region in which it is located. Ciénegas are freshwater to brackish North American wetlands associated with fluvial systems of arid/semi-arid areas of the southwestern U.S. and northwestern Mexico. Once extensively utilized by the region's indigenous human cultures, early...
