Farmers have known for centuries that fertilizer and irrigation help boost crop growth. But how does long-term application of fertilizer and water affect the composition of surrounding plant communities? In a study based at the Cedar Creek LTER, early signs suggest that added water and nutrients support the survival of new species and encourage more… Read more »
LTER Network presentations and posters at American Geophysical Union (AGU) Meeting 2018
Researchers Frederik Schulz (US Department of Energy’s Joint Genome Institute) and Lauren Alteio (University of Massachusetts) have discovered sixteen new giant viruses in soil samples from a long-term research site at the Harvard Forest LTER, described in a Nature Communications paper published in November 2018. Giant viruses are larger than most single celled organisms, and tend… Read more »
Western black widow spider populations in urban locations are more diverse than those in rural locations
Researchers at the Virginia Coast Reserve LTER recently found that adjacent patches of salt marsh and seagrass increase sedimentation benefits in shallow coastal bays.
Kelp forests have long been known to harbor a high number and diversity of marine species, from tiny crustaceans to large fish and marine mammals. This biodiversity tends to be attributed to the complex structure and productivity of giant kelp, earning it the title ‘foundational species’. Surprisingly, however, little quantitative data has been assessed to… 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.

The ebb and flow of the tide through coastal salt marshes brings wide swings in temperature, salinity, oxygen levels and pH. Many of these fluctuations occur at short timescales (e.g. multiple times per day) and have a profound impact on both the types of microorganisms that can exist in such a dynamic environment, and how… Read more »
