NORTH CAROLINA: Three new Sea Grant projects could have local impact

February 3, 2020 — As of Feb. 1, a new batch of research projects are underway through the N.C. Sea Grant. The research and education organization, headquartered at N.C. State in Raleigh, facilitates funding for projects up and down the coast, and considers those that will be of importance to the whole state, said Katie Mosher, spokeswoman for N.C. SeaGrant.

Among the ten new projects for 2020-2022, a few could have special importance to Southeastern North Carolina. Here are some of the questions that researchers are trying to answer.

Blue Crabs and Climate

Jessie Jarvis, a coastal plant ecologist at the University of North Carolina Wilmington, is the lead researcher taking a closer look at one way that North Carolina, which is a transition zone between temperate and tropical climates, could be affected by changing temperatures. Jarvis’ research interests include underwater grasses, or submerged aquatic vegetation. It’s predicted that subtropical vegetation species will increase their range into local waters, and the potential impacts are unknown, especially for important species such as blue crabs. She plans to look at different vegetation meadow types and how they may impact different species, which could inform how these fisheries are managed and conserved.

Could tiny pieces of plastic in fish become a big problem for humans?

July 30, 2019 — Most of us would agree that plastic waste is a problem.

The sheer amount of plastic thrown away by humans is staggering and easy to see on roadsides, in landfills and oceans.

Plastic bags and water and soda bottles are easily identifiable forms of plastic trash but what happens when those items break down into what are called microplastics?

The short answer is that animals eat these plastic pieces less than five millimeters in size, and a research team at UNCW is studying how contaminants in the plastic might be transferred from prey to black sea bass.

“The goal is to assess how these black sea bass might be impacted by plastic pollution,” said Cheyenne Stienbarger, a masters student at UNCW who is part of the research team. “Black sea bass are a commercially and recreationally important species along the east coast, particularly in North Carolina. We’re really hoping to get a better understanding of how these fish might be impacted.”

Why are North Atlantic right whale numbers declining?

One of the world’s most endangered animals used to be routinely seen off the NC coast. Not anymore.

November 27, 2017 — WILMINGTON, N.C. — After years of steady improvement, one of the Atlantic ocean’s most at-risk whales — a species with strong ties to North Carolina — is in perilous decline, according to researchers.

The North Atlantic right whale, historically a target for harpooners, saw its population improve from 270 whales in 1990 to 483 in 2010, according to research led by Richard Pace of the National Oceanic and Atmospheric Administration (NOAA)’s Northeast Fisheries Science Center, based in Woods Hole, Massachusetts. The population fell to 458 whales by 2015.

“When you’re talking about a population that’s somewhere between 400 and 500 individuals, you can never let your guard down. And you can never assume that things are going well,” said Ann Pabst, a University of North Carolina Wilmington (UNCW) zoologist whose lab focuses on marine mammals.

The downward trend continued in 2017, with 16 North American right whales dying, putting the species’ population in decline and at risk of endangerment. The Pace team’s research indicates the female population declined about 7 percent from 2010 to 2015, while the male population dropped about 4 percent.

Right whales are likely not breeding quickly enough to replace their deceased counterparts, according to the Pace team’s study, with the plight further enhanced by female whales dying at a faster rate than males. Bill McLellan, who works with UNCW’s Marine Mammal Stranding Program, explained some of the reasons behind it.

“Females have a lot riskier life. They spend a lot more time up and down the coast, they migrate a lot more to give birth,” McLellan said. “Males generally stay north. … They’re sitting in one location, and they’re not exposing themselves to the mortality factors.”
