The hemlock is a native tree species that was once common from northern Alabama to Nova Scotia. Stretching tall with thick needles, the hemlock creates an entire ecosystem beneath its large branches. In the Smoky Mountains, its shade used to cool streams just enough to allow the eastern brook trout to thrive. Unfortunately, these hemlocks are in dramatic decline.
The National Science Foundation Long-Term Ecological Research (LTER) Network presents an overview of the rich and varied research taking place at its 28 sites. In 2018, the topic of this annual half-day symposium is ocean ecosystems and their connections to marine species and human well-being.
At first glance, the grasshopper sparrow may not look like much. Native to the tallgrass prairies of the American Great Plains, it’s a small brown and black-speckled bird with a wingspan of 8 inches. But this little bird is gaining recognition for its unusual behavior: it has an amazing ability to cover long distances over… Read more »
Although coral reefs have been the subject of ecological studies for nearly a century, the role that environmental conditions play in coral development is still a partial mystery. LTER researchers at Mo’orea Coral Reef have been exploring coral-environmental interactions in an effort to better understand coral growth. The team recently investigated how two key abiotic… Read more »
When we think of forest ecosystems, we usually picture dense thickets of trees, the vibrant buzz of insects and birds, and lush undergrowth carpeting the floor. We often fail to recognize the complexity hidden beneath the surface—a vast and ancient network of fungi, called mycorrhizae interwoven with every plant root. These 450 million year-old symbiotic… Read more »
The majority of grasslands around the world have been destroyed or converted for human use, either for agricultural or urban development. In North America, for example, only four percent of the once vast tallgrass prairies are left. Understanding grassland community dynamics could be a critical part of conserving those that remain. Plant-pollinator relationships are… Read more »
The boat whizzed past the mangrove trees in Everglades National Park, creating a blur of blue water and green leaves. Rafael Travieso, our captain and lead technician for Florida Coastal Everglades (FCE) LTER, expertly guided us through Shark Slough to a partially hidden wooden dock. Slowing down, we glided forward until the tip of the boat barely tapped the wooden structure, which created a platform for a solar panel and what looks like a barrel.

Viviana Mazzei studies organisms that cannot be seen with the naked eye. When I toured the Florida Coastal Everglades LTER research sites in Everglades National Park, my eyes were drawn to the mangrove trees, the dolphins, the birds. But when Mazzei, a Ph.D. student at Florida International University, wades through these ecosystems, she is on the look-out for something much smaller: diatoms, a type of single-cell algae, that thrive in this aquatic environment.
I paused at the top of Coweeta Hydrologic Lab’s transect #327, peering down, down, down at the slope beneath me. Katie Bower, a research technician at Coweeta, and two summer interns had already started down the narrow pathway, accustomed to its slippery leaf layer and sharp contours.
During their week out at the University of Georgia Marine Institute on Sapelo Island, teachers divide their time between assisting with research in outdoor settings alongside GCE scientists and graduate students and discussing the implementation of the information and experiences into their own teaching settings.
