Native soil carbon (C) can be lost in response to fresh C inputs, via the “priming effect,” a phenomenon observed for decades yet still not understood. Using dual-stable isotope probing, Ecoss research showed that priming involves changes in the diversity Read more…
The mass emergence of metamorphosed aquatic insect larvae as airborne adults provides an important seasonal pulse of prey biomass to many aquatic ecosystems. Ecoss research explored whether the type and quality of leaf litter on which these aquatic larvae feed Read more…
Pollution scenarios and anthropogenic warming are familiar examples of human-caused stress on the environment. But human-driven loss of biodiversity itself robs ecosystems of essential players and services, damaging ecosystem function. Ecoss research examined the effects of various environmental stressors on Read more…
Rising global temperatures and CO2 levels are increasing the amount of global-warming methane (the flaming red molecule depicted here) produced by rice farming: with more CO2 in the air to pull in for photosynthesis, rice plants grow faster and supply Read more…
Researchers at Ecoss helped to uncover a potent offset to carbon “drawdown” by plants: with more CO2 available to fuel photosynthesis in the air above, soil microbes consume more sugars oozing from the roots of the faster-growing plants and increase Read more…
Albedo, the reflectance of sunlight from earth’s surface, is an important moderator of climate because it determines whether solar energy is locally absorbed or re-radiated to space. Ecoss-associated research characterized the albedo and other energy fluxes of various landscapes to Read more…
Management of forests for carbon uptake is an important tool in the effort to slow the increase in atmospheric CO2 and global warming. However, some current policies governing forest carbon credits actually promote avoidable CO2 release and punish actions that Read more…
Longstanding land-management policies of complete wildfire suppression on wild lands were intended to prevent catastrophic wildfires through constant human monitoring and intervention. However, when combined with policies that prohibit logging or thinning in protected areas, total fire suppression can lead Read more…
The latest Ecoss artistic product, “The Ascent of Sap Rap”, by George Koch and students from his “Plants and Climate” class. View the full video here. See lyrics below: For plants on terra firma it’s a struggle to stay wet Read more…
Scientists believe that biochar, the partially burned remains of plants, has been used as fertilizer for at least 2,000 years in the Amazon Basin. Since initial studies published several years ago promoted biochar, farmers around the world have been using Read more…
