Tropical forests are sometimes referred to as the “lungs of the planet,” and for good reason – the high plant biomass of tropical regions produces a large portion of the oxygen we breathe and absorbs significant amounts of carbon dioxide. Rainfall, nutrient availability, and amount of disturbance (natural or human) a forest experiences can all… Read more »
A recent meta-analysis found that aridity and low soil nitrogen levels seem to limit — rather than stimulate — plants’ ability to increase production of fine roots under elevated carbon dioxide conditions.
It stands to reason that a diverse biota would support a diverse range of ecological functions — and the experimental evidence has borne that out at the scale of species and plots. But does the same relationship hold at the scale of communities and landscapes? A large group of researchers, led by former Cedar Creek LTER… Read more »
Researchers at the North Temperate Lakes (NTL) LTER site have capitalized on the utility of Peter and Paul experimental lakes in northern Michigan in order to improve predictions of ecological tipping points in lake ecosystems. Their two-year study analyzes changes in the lakes’ spatial characteristics, and identifies statistical patterns in those characteristics as potential predictors of ecological… Read more »
Five thousand years ago, Native Americans lived and thrived on Georgia’s coast. Shellfishing, especially the Eastern oyster (Crassostrea virginica), was a significant cultural practice of these coastal Natives Americans. Today, Georgia’s coast is peppered with oyster shell deposits from long-term native American consumption. While studying archaeological shell deposits on Georgia’s coast, researchers with the Georgia Coastal… Read more »
Within the science and natural resource management fields, people often say what gets measured gets managed. But in a well studied ecosystem such as the Everglades, how do decades of scientific information get accurately translated into restoration plans? Through the use of synthesis science, researchers from the Florida Coastal Everglades LTER site compiled interdisciplinary data to evaluate… Read more »
In the United States, society spends billions of dollars each year on stream restoration. Knowing where restoration efforts are likely to be most effective could help get more restoration-bang for those bucks. A recent study of 13 river restoration projects by investigators from the Baltimore Ecosystem Study LTER found that restoration appeared to be more effective at… Read more »

This removal may lead to a more enjoyable experience for humans, but it constitutes a major loss of habitat for sandy beach critters, which use… Read more »

CC BY-SA 3.0.In the digital age, while public access to information about parks and public land conservation is readily available, records on private-land conservation remain incomplete and inconsistent. To reveal the reasons behind the gaps in data on private-land conservation, LTER-funded researchers analyzed maps and documents, and conducted interviews focused on four major… Read more »
If carbon is currency, wildfires are the brokers; that is, they distribute carbon between land and air. In the short-run, fire emits carbon dioxide into the atmosphere. Over time, it also strengthens subsequent carbon uptake through plant regrowth. This exchange is like a natural Ponzi scheme – the carbon offsets from yesterday’s fires take up today’s emissions….
