LTER Road Trip: A Hot Time in the Forest

Posted

To evaluate the effects of soil warming, scientists have measured soil gases including methane, nitrous oxide, and carbon dioxide as well as nitrogen fluxes every month since 1991, comparing the heated plots to control plots nearby. One of the most interesting results they have documented comes from the forest’s tiniest organisms – the microbes that digest downed leaves and branches (also known as the ecosystem’s detritus). At first, the microbes worked overtime in the heated plots, releasing more carbon dioxide through their respiration.

LTER Road Trip: Hemlock Hospice

Posted

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.

2018 NSF LTER Symposium: Understanding Our Ocean Connections

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.

The Grasshopper Sparrow – Breeding Nomad of the Grassland Prairie

Posted

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 »

Grow with the flow: evaluating the interactive effects of seawater conditions on coral growth

Posted

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 »

Resilience on the Prairie: Disturbance Effects on Grassland Plant-Pollinator Communities

Posted

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 »

LTER Road trip: Wildlife-Equipment Interactions in the Jungle

Posted

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.

LTER Road Trip: How Tiny Algae Could Predict Changes in the Everglades

Coastal mangroves in Everglades National park

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.
