Tennessee Aquarium fellowships bring minorities into the science space

CHATTANOOGA — Never let it be said that all summer jobs are created equal.

Squatting on his heels to dangle the flexible hose of an environmental DNA pump into a briskly flowing North Georgia stream, the last few weeks have been anything but ordinary for Spencer Trimpe. With the pump’s droning motor steadily collecting a sample of water to filter out genetic traces of the stream’s inhabitants, he doesn’t bother holding back a smile.

A lanky junior biology major from Thomas More University, Trimpe is one of two students selected as part of the Tennessee Aquarium’s George Benz Aquatic Ecology Fellowship. Instead of manning a cash register or waiting tables this summer, he’s assisting freshwater scientists from the Tennessee Aquarium Conservation Institute with a variety of research projects.

NYT: Recovering America’s Wildlife Act a big bipartisan push to preserve animal species

New York Times columnist Margaret Renkl noted recently that a precious opportunity has presented itself to strengthen wildlife-protection laws and add to environmental protections across the nation.

The Nashville-based journalist said the act, known as RAWA, “is poised to become the single most effective tool in combating biodiversity loss since the Endangered Species Act.” The resolution is carried in the House by Michigan Democrat Rep. Debbie Dingell.

“This bill provides funding for (1) the conservation or restoration of wildlife and plant species of greatest conservation need; (2) the wildlife conservation strategies of states, territories, or the District of Columbia; and (3) wildlife conservation education and recreation projects,” according to the U.S. Congress.

“The Department of the Interior must use a portion of the funding for a grant program. The grants must be used for innovative recovery efforts for species of greatest conservation need, species listed as endangered or threatened species, or the habitats of such species.

“In addition, the bill requires certain revenues generated from fees and penalties for violations of environmental requirements to be used as a source for the funding.”

The legislation, which has already passed the House of Representatives, would allocate $1.4 billion each year across the country to protect and restore endangered plant and animal populations, and protect species already tipping toward endangered status. It is up for consideration in the Senate, where it has already garnered the support of at least a dozen Republicans and a majority of Democrats, virtually ensuring its passage, according to Renkl.

“You don’t have to nurse a fondness for spotted owls or snail darters — creatures at the heart of two of the most contentious environmental debates in recent history — to understand that what is best for the ecosystems we share with nonhuman animals is what’s best for us, too,” Renkl wrote.

Georgia’s Ocmulgee River is a case study in the decline of Southern river fisheries, and their revival

Ethan Hatchett is a writer for the Georgia Department of Natural Resources.

MACON — The Ocmulgee River has changed. The cloudy water once ran clear. The sandy bottom was once rocky. Fish swam upriver to breed from places as distant as the Altamaha River, which the Ocmulgee and Oconee rivers join to form near Lumber City and the Atlantic Ocean.

European settlement changed the river. Centuries of agriculture and development stripped away much of the land’s vegetation that filtered the flow, causing the Ocmulgee to fill with sediment. The soil particles gradually moved through the waterway, covering gravel that fish spawned in, smothering fishes’ eggs, mucking up the water and even building up on the banks, saturating the ground with sediment.

It is impossible to know how many freshwater fish the Ocmulgee lost since the first Europeans arrived. Many species disappeared without being discovered. Yet on a clear afternoon in May, DNR aquatics biologist Paula Marcinek led a team on the upper Ocmulgee in search of robust redhorse, a “lost” fish found in 1991.

Read DNR’s blog post about efforts to restore the robust redhorse, plus news of a new grant that will expand the work and rare video of these fish spawning.

Emblematic brook trout get a second chance at home in Southern Appalachian streams

Casey Phillips is a writer for the Tennessee Aquarium.

CHATTANOOGA — A team from the Tennessee Aquarium, Tennessee Wildlife Resources Agency and Trout Unlimited hiked along — and occasionally waded through — a pristine tributary of South Fork Citico Creek in Cherokee National Forest. 

 Navigating an obstacle course of tangled mountain laurel branches and moss-slickened boulders in late May, the team followed the stream as it gently descended through the Appalachian uplands. When a calm pool or shaded rocky overhang presented itself, they paused to dip their nets into five-gallon buckets filled with wriggling juvenile Southern Appalachian brook trout.

These little fish, raised to about two inches over six months, were the focus of more than six months of work at the Tennessee Aquarium Conservation Institute and the impetus for the hours-long trek into the East Tennessee woods.
