2018 ESA Annual Meeting Presentations In the past year alone, extreme events including hurricanes, droughts, and extensive fires have impacted significant regions of the United States—affecting the health of both natural habitats and human communities. Fittingly, the theme of this year’s Ecological Society of America (ESA) annual meeting is ‘Extreme events, resilience and human well-being.’… Read more »
On the boundaries of fresh and saltwater systems, coastal marshes give rise to diverse, productive ecosystems that act as carbon sinks. Their secret? Freshwater marsh plants receive just the right amount of nutrients and salt from periodic seawater tides to thrive. However, incursions of saltwater into these systems are increasing —often caused by drought and… Read more »
Observed benefits of carbon dioxide enrichment to C3 v. C4 plants appear to reverse after 12 years of treatment.
The Yahara may sound like the name of a vast desert, but it’s actually a 359-square mile watershed in southern Wisconsin. The Yahara Watershed is a mix of urbanized land (including the state capital), productive agriculture land, and a chain of lakes called the Yahara Lakes. Because of its diverse environment, the Yahara provides many… Read more »
Climate change is already impacting polar habitats such as the Arctic tundra, where increasing temperatures are causing permafrost to thaw and exposing soil and organic matter that have been buried for thousands of years. Many scientists predicted that this soil, once exposed, would release a massive amount of sequestered carbon into the atmosphere, contributing to… Read more »
As temperatures rise in many regions around the world, plant species whose ranges were previously limited by low temperature thresholds and intolerance to freezing are increasingly able to expand into new areas and possibly overtake established vegetation regimes. On Hog Island, an undeveloped barrier island off the coast of Virginia, a group of LTER researchers… Read more »
Dan Dillon, Ben Glass-Siegel, Nate Vandiver, and I stood at the edge of a Baltimore road. Cars whizzed by overhead as Glass-Siegel and Vandiver picked their way through dense grass to the river running swiftly beneath the bridge, the blades swishing against their long pants as they blazed a path to the rocky shoreline.
I like to think of Dr. Neil Pederson as a detective. We met in his office at the Harvard Forest Long Term Ecological Research site (HFR-LTER), on the second floor of one of their many beautiful buildings in what feels like a college campus. Multiple sections of tree trunks sit here and there, polished so that the tree rings are clearly visible. Post-it notes and circular stickers mark years of particular interest.
