Gulf of Mexico (Gulf) fisheries account for 41% of the U.S. marine recreational fish catch and 16% of the nation's marine commercial fish landings. Mercury (Hg) concentrations are elevated in some fish species in the Gulf, including king mackerel, sharks, and tilefish. All five Gulf states have fish consumption advisories based on Hg. Per-capita fish consumption in the Gulf region is elevated c...

Highly structured nursery habitats promote the survival of juvenile stages of many species by providing foraging opportunities and refuge from predators. Through integrated laboratory and field experiments, we demonstrate that nursery habitat structure affects survival and predator-prey interactions of red king crab Paralithodes camtschaticus. Crabs (<1 yr old [Age 0]; 8 to 10 mm carapace lengt...

Visual primitives have long been proposed, under the name of geons or generalized cylinders, as components for object models in the brain and in the computer. Geons constitute a structural level intermediate between features and whole objects, and can form a basis for powerful generalization between different view points. We here present a system for the extraction of geon models from images of...
