Warmer winters — not overfishing — have depleted Chesapeake Bay oyster populations in recent decades, researchers have found. The changing environment affected oysters, clams and scallops up and down the East Coast of the United States, according to a study.
Scientists are using a crab virus akin to the common cold, computer models of ocean currents and tides, and genetic analysis of crustaceans from Massachusetts to Argentina to figure out just how much different populations of swimming crabs have in common.
It wasn't just a surge of debris that washed into the Chesapeake Bay last month — the estuary received a record-setting flow of fresh water, scientists say, potentially hinting at long-term impacts on ecosystem health.
New research suggests that if anglers, watermen or even bowhunters kill too many of the Chesapeake Bay's cownose rays, the oft-maligned creatures could disappear from the estuary. Smithsonian Environmental Research Center scientists found that rays often return to the same rivers each year.
In a study published in one of science's premier journals, researchers have concluded that Chesapeake Bay cleanup initiatives have triggered a major resurgence of underwater grasses, which are at the center of the estuary's fragile food web.
Rebecca Stevick is an Old Town native and graduate student at the University of Rhode Island whose research focuses on oysters and the environmental conditions that help them thrive. She was awarded a grant in April from the Nature Conservancy and the Coastal Institute to study how bacteria functions in oysters and what impact they have on Rhode Island's Narragansett Bay.
Biologists are investigating an unusual number of humpback whale deaths along the Atlantic Coast since the beginning of 2016, including six in recent months at the mouth of the Chesapeake Bay or on the Delmarva Peninsula.
A six-year, federally funded research effort suggests the Chesapeake Bay's increasingly hardened shoreline could be hindering the estuary's recovery from decades of pollution and abuse. It could be limiting where crabs, fish and terrapins can find food and shelter, while contributing to the spread of an invasive marsh grass.
Emily Fair, a science teacher at Francis Scott Key High School in Union Bridge, Md., was chosen to participate in an eight-day Marine Education Fellowship sponsored by Ecology Project International, studying Mexico's ecologically critical environment, collecting green sea turtles and learning to how incorporate field studies in their own classrooms.
With seafood fraud a continuing problem in Maryland and across the nation, environmentalists, fishermen and lawmakers are expressing concern about a decline in the number of special investigative agents and enforcement cases at the National Oceanic and Atmospheric Administration.
The Board of Carroll County Commissioners signed a letter on Thursday stating their intent to join Dorchester and Kent Counties in their efforts to persuade federal and state agencies to allow them to engage in oyster restoration in the Chesapeake Bay.
This year at the aquarium, 25 students in grades seven through nine are enrolled in the summer program at the National Aquarium where they work with blue crabs and water to investigate what goes on under the sea.
For as long as anyone can remember, wild orchids have rewarded sharp-eyed hikers in Maryland's Catoctin Mountains with pink, yellow and white blooms peeping from the forest floor. But these "secret beauties," as one researcher dubbed them, are vanishing at an alarming rate.
More than 1,000 mourners gathered Wednesday at the U.S. Naval Academy chapel to say goodbye to midshipman Hans P. Loewen, remembered as an adventurous, vibrant, funny man whose company mates summed him up in a phrase: "live like a warrior."
Pasadena resident Bill Hubick and Jim Brighton of Easton launched the Maryland Biodiversity Project, an effort to do something no one has ever done — catalog examples of every living thing in Maryland on one website: marylandbiodiversity.com.
Scientists believe a virus similar to measles in humans is responsible for an unusual die-off in bottlenose dolphins along the Mid-Atlantic coast. The death toll has continued to rise in August and could remain a threat to the dolphin population through next spring, the scientists said.
