Invasive species: A few bucks and a click away

ist of 100 worst invasive species are from aquarium and ornamental releases.

Padilla and Williams make several suggestions for regulation, including listing native and/or safe alternative aquarium and ornamental species to encourage the trade of less invasive and aggressive species. They also suggest a trade-off using bonds equal to the estimated cost of repairing future damage that could occur in the worst-case scenario of a particular animal or plant escaping into the wild.

Deep Sea Corals
Also in this month's issue of Frontiers in Ecology and the Environment, Santi Roberts and Michael Hirshfield (Oceana) discuss the diversity and biology of deep-sea corals. First observed over 200 years ago, scientific knowledge about these organisms continues to increase as new technologies allow researchers to delve deeper and farther into the ocean than ever before. Deep sea corals, much like their better-known tropical cousins, are found throughout the world, living in darker and colder places, and with equal diversity and reef building capabilities. These corals also provide habitat for economically important species of fish including grouper, bass, jacks, snappers and sharks.

Like all reefs, these corals are susceptible to damage by trawling. Roberts and Hirshfield make several suggestions for better protecting these resources, including protecting untrawled areas, enhancing the enforcement of current regulations, and more research into restoring damaged deep-sea coral communities.
