This dataset shows innundation from the terrestrial ecosystems (reference classification) of South America, Central America, and Mexico. South America: This dataset represents Ecological System patches using various reference datasets. Original data generarated from 2000 era data, modeled in 2005 and updated in 2008 and 2010.Originally, this project developed a GIS modeling approach, using a variety of abiotic and biotic data sets, to produce a map of the distribution of Latin America and Caribbean (LAC) ecological systems throughout South America for use in ecoregional assessments. Ecological systems, defined as spatially co-occuring assemblages of vegetation types sharing a common underlying substrate, ecological...

Ecological systems, defined as spatially co-occuring assemblages of vegetation types sharing a common underlying substrate, ecological process, or gradient, were identified for all...

The diked and freshened Herring River estuary (Wellfleet, Massachusetts) experiences regular summer hypoxia and one- to three-week periods of main stream anoxia, often accompanied by fish kills. Stream hypoxia results from the temperature-dependent increase in oxygen demand of organic matter released by diked salt marsh deposits; periods of total anoxia are induced by heavy rains which increase the runoff of wetland organic matter. Historic reductions in tidal flushing have extended the low salinity region of the estuary normally characterized by high organic loads and minimal flushing. Recurrent main stream anoxia has depressed both migratory and resident aquatic fauna.
