On an early result on stability and complexity

Published in American Naturalist, 1999

In a recent paper, Solow and Beet (1998) showed that the links in observed community food webs are not randomly distributed. Instead, these webs appear to be lumpy in the sense of being composed of relatively tightly connected compartments …

An estimate of the cost of acute health effects from food- and water-borne marine pathogens and toxins in the USA

Published in Journal of Water Health, 2011

Large and growing segments of the United States population consume seafood or engage in marine recreation. These activities provide significant benefits but also bring risk of exposure to marine-borne illness. To manage these risks, it is important to understand the incidence and cost of marine-borne disease. We review …

When wind speeds are 2–10 m s−1, reflective contrasts in the ocean surface make oil slicks visible to synthetic aperture radar (SAR) under all sky conditions. Neural network analysis of satellite SAR images quantified the magnitude and distribution of surface oil in the Gulf of Mexico from persistent, natural seeps and from the Deepwater Horizon (DWH) discharge …
