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 »

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 »
Many ecological functions depend on symbiosis, where two organisms come together to form emergent traits neither displays alone. Microbes like bacteria and viruses are often at the center of these interactions. A new $12.5M National Science Foundation (NSF) grant will fund an ambitious endeavor to synthesize biological data across several disciplines to study the role… Read more »
The National Science Foundation (NSF) recently announced ten new awards for its Critical Zone Collaborative Network (CZCN), and LTER sites will play a prominent role in four of them. The awards fund a wide range of investigations to better understand the ‘critical zone’, the area of our planet where water, air, soil, rock and living… Read more »
Credit: Laura Templeton We’ve all spent the majority of 2020 stuck inside. As we’ve been staring out our windows longing to return to our ‘normal’ lives, where we can meet co-workers in the coffee room or catch up with our favorite podcasts on our commute, we might have noticed some interesting wildlife behavior. Maybe we… Read more »
The year 2020 is the 40th anniversary of the Long Term Ecological Research (LTER) Network and we were looking forward to grand celebration at the Ecological Society of America’s 2020 Meeting. While we cannot share our enthusiasm in person this year, meeting participants will find a cornucopia of pre-recorded talks, online posters and live-online discussions…. Read more »
As boreal forest wildfires increase in severity and frequency, new patterns of post-fire recovery are emerging. Research led by Jill Johnstone at Bonanza Creek LTER has found that recent wildfires led to changes in tree species dominance that are persisting through post-fire succession in Alaskan boreal forests, indicating the potential for a widespread shift in… Read more »
Every year, the Eastern North Pacific population of blue whales migrates between their winter calving grounds off the coast of Mexico and their summer feeding grounds in the California coastal region. Scientists know that they time their migration to coincide with peak prey abundances, but the cues they use for this have been unknown—until now…. Read more »
