A new study shows that when enough bacteria get together in one place, they can make a collective decision to grow an appendage and swim away. This type of behavior has been seen for the first time in marine sponges, and could lead to an understanding of how to break up harmful bacterial biofilms, such as plaque on teeth or those found on internal medical devices like artificial heart valves.
"Stop acting like we're bulletproof" urged Congressman Elijah Cummings at the kick off of a two-day conference on the Chesapeake Bay and human health at the Institute for Marine and Environmental Science at Baltimore's Inner Harbor, May 14-15.
Solomons, Md. (August 31, 2011) – According to recent research, published in the journal Marine Ecology Progress Series (Vol. 436), the oyster population in the upper Chesapeake Bay has been estimated to be 0.3% of population levels of early 1800s due to overfishing, disease, and habitat loss.
Chesapeake Oyster Population Less Than One Percent of Historic Levels
A research effort designed to prevent the introduction of viruses to blue crabs in a research hatchery could end up helping Chesapeake Bay watermen improve their bottom line by reducing the number of soft shell crabs perishing before reaching the market. The findings, published in the journal Diseases of Aquatic Organisms, shows that the transmission of a crab-specific virus in diseased and dying crabs likely occurs after the pre-molt (or ‘peeler’) crabs are removed from the wild and placed in soft-shell production facilities.

Based on a comprehensive analysis of the latest scientific findings and new data, UMCES researchers Dr. Margaret Palmer and Dr. Keith Eshleman are leading a group of leading environmental scientists calling on the U.S. Environmental Protection Agency and the U.S Army Corps of Engineers to stay all new mountaintop mining permits.

Satellite tracking informs maps of blue whale density off West Coast
Scientists have long used satellite tags to track blue whales along the West Coast, learning how the largest animals on the planet find enough small krill to feed on to support their enormous size. Now researchers from NOAA Fisheries, the University of Maryland Center for Environmental Science, and Oregon State University have combined that trove of tracking data with satellite observations of ocean conditions to develop the first system for predicting locations of blue whales off the West Coast.
Scientists from the University of Maryland Center for Environmental Science are part of a unique project designed to strategize new ways to manage an old industry. With the fate of the Chesapeake Bay’s oyster population in question, stakeholders ranging from watermen to environmentalists hope to look past any differences to reach a common goal—enhance the shellfish resource and fishery.
Do you know why bubbles form in a pot of boiling water? It’s the oxygen leaving the liquid. The same thing is happening as a changing climate warms up our oceans. It’s called deoxygenation, or ocean suffocation. When the water warms up, it holds less oxygen for living creatures to use. At the same time, animals’ need for oxygen increases as the temperature rises. A double whammy.
