Non-native species have invaded over 80 percent of marine regions on Earth, including remote Antarctica. More than half of these species are considered harmful in their invaded habitats, causing changes in native marine ecosystems and exacting stiff economic costs from marine industries such as shipping and aquaculture (which are two of the main pathways for introductions). This presentation will review prevention methods for ship ballast water; hull fouling; the aquarium trade; and, an emerging concern, plastic debris. It will also review the effects of marine invasive species, including human illness, altered food webs, and disrupted ecosystem services provided by marine wetland plants (salt marshes, seagrasses). It will describe the need for continued attention to marine invasive species in the face of climate change and warming oceans.

Symposium: Waste Not, Want Not: Waste As the World's Most Abundant Renewable Resource
A significant portion of the 130,000 tons of waste manure produced annually from the approximately 2 million dairy cows in central California could be turned into fuel and energy sources, including heat and gaseous, liquid or solid fuels. This presentation will describe some possibilities. For instance: Processed manure along with other biomass from urban and other agricultural sources can yield biomethane, a product equivalent to natural gas. In California's Central Valley, many dairies are located near compressed-natural-gas (CNG) filling stations and gas p
