When one envisions a grassland community, imagery of tall grasses and bison often come to mind. Bison are an iconic species on the landscape, and they also impact the structure and function of the grassland ecosystem in important ways. Using natural variations in the abundance of oxygen isotopes, researchers at the Konza Prairie LTER found that grazing influenced plant water use through changes in diversity.
Between 2013 and 2015, Andrew Rypel traveled the state of Wisconsin attending public meetings led by state and local fisheries staff— always with a set of graphs in hand.

In 2010, when Cyclone Oli hit the reef, Han wondered which way the scale would tip: could the coral recover from both these impacts? Or would macroalgae move in and dominate?
New research by Harvard Forest (HFR) LTER scientists suggest that widespread death of the whiteback pine tree from beetle infestations and tree disease outbreaks may be affecting seed production and hence the future of the tree–a mountain tree important to wildlife and water resources in the western United States and Canada. In a paper published… Read more »
The National Science Foundation’s online video magazine, “Science Nation,” has released a short video featuring long term research by scientists at the Harvard Forest (HFR) Long Term Ecological Research (LTER) program to determine how the forest responds to carbon dioxide in the atmosphere. The short video and the accompanying short article can be viewed at… Read more »
