To promote the analysis and synthesis of Arctic data, as well as to inform ongoing development of the NSF data repository, the Arctic Data Center is soliciting requests for proposals for a Synthesis Working Group, with research to begin by October 2018. Funding is available for one Working Group, consisting of hosting two meetings of approximately 15 participants each, over… Read more »
Fire is a natural force that has shaped grasslands for millennia, and it remains crucial for managing and conserving tallgrass prairie today. Fire also inspires and captivates the human spirit. Can grassland fires also be used to produce art? Erin Wiersma, Associate Professor of Art at Kansas State University, is exploring how recently burned prairie… Read more »
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. Taking a deep breath, I followed slowly behind.
I flip open my copy of The Franklin Press while sipping coffee at a field station, and there, in a bi-monthly column, is an article by Coweeta Hydrologic Lab staff, answering the scientific questions of local citizens. The column is just one part of the Coweeta Listening Project (CLP), an initiative of the Coweeta LTER.
This issue features articles that present a wide set of themes including historical facts, a vision for collaboration strategies given new partnerships and challenges, descriptions of systems that produce EML packages to deposit data in data repositories, individual experiences of special events like the 2017 solar eclipse and a tropical hurricane, and information management post-LTER… Read more »
Salamanders are very sensitive to changes in both precipitation and temperature, and scientists at the Coweeta Hydrologic Lab have discovered that they represent a hotbed of evolutionary activity. That’s right – evolution is happening before our eyes, in real time.
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.
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 »
