Ecosystems resist devastation from hurricanes by choosing either of two strategies: high resistance or high resilience.
All plants are somehow affected by global change, but their responses are inconsistent between ecosystems, a LTER Synthesis group finds.
For Southern California reefs and beaches, giant kelp fuels the food web and creates an environment in which biodiversity booms. But the nutritional quality of kelp is lower than it once was, a new study from the Santa Barbara Coastal LTER shows. The culprit? Climate change and warming ocean water, coauthors Dr. Heili Lowman and Kyle Emery find.
Scientists have been consistently documenting environmental changes at research sites like this one in the Cascade Mountains for decades. US Forest Service Michael Paul Nelson, Oregon State University and Peter Mark Groffman, CUNY Graduate Center Record-breaking heat waves and drought have left West Coast rivers lethally hot for salmon, literally cooked millions of mussels… Read more »
Wildfires have made headlines worldwide in recent years — and for good reason. Evidence points to increasing wildfire frequency and intensity across many vulnerable ecosystems as climate change impacts grow ever more evident. However, periodic wildfires in ecosystems adapted to them can actually help inhibit plant disease outbreaks, according to new research from Cedar Creek… Read more »
Two new synthesis working groups, awarded in 2021, capitalize on the intensive and extended record of observation at LTER sites to shed light on thorny ecological questions.
By Natasha Griffin, PhD candidate at Oregon State University The staff of the H.J. Andrews Experimental Forest LTER site had almost no time to prepare when a massive wildfire swept through the region in early September. Stoked by dry late-summer conditions and extreme high winds, Oregon’s Holiday Farm fire began spreading rapidly as soon as… Read more »
As ecosystems respond to human activity, what organisms will emerge as new trailblazers, shaping the diversity and resilience of these changing environments? And how can land managers identify these species early on to better prepare for the future? Forests of southern Appalachia have a history fraught with human activity. Hardy and towering, American chestnut and… Read more »
By Haley Dunleavy, PhD Candidate at Northern Arizona University Leaving my house, I feel like a runaway. I am packed inside an economy-sized rental car with my field clothes, camping gear, and of course, face masks, heading 300 miles north to meet my advisor Michelle Mack and fellow lab members for a couple days of… Read more »
Climate change is hitting Arctic ecosystems hard – permafrost is rapidly thawing, releasing previously-frozen organic matter into the surrounding environment. Knowing not only how, but when, dissolved organic matter (DOM) and other nutrient concentrations are changing is important for predicting effects of climate change, but the picture is currently incomplete. A new paper from Arctic… Read more »
