Ecology & Genomics offer new approaches to combat antibiotic resistance

Antibiotic-resistant bacteria are widespread and are increasingly associated with human infections.  Inappropriate antibiotic use – both in people and in animals raised for food – drives the evolution of multi-drug-resistant pathogens and threatens a post-antibiotic era – one in which minor infections can kill. The majority of antibiotics are actually sold for use in food […]

Linking soil bacterial biodiversity and soil carbon stability

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 and composition of two functional bacterial groups: a single-substrate pulse […]

Fire, Management, and the Global Carbon Cycle

Overview Fire, a natural ecological disturbance, has been suppressed in U.S. forests for much of the past century. This has prevented damage to property and protected timber resources, but has caused many forests to develop in an unnatural manner, resulting in dense stands of small trees that are now poised […]

Linking Biogeochemistry and Microbial Community Chemistry

Overview The identities of organisms profoundly influence ecosystems, and microbial diversity is vast. The obvious disconnect between this diversity and its treatment in C cycling models is perhaps the best manifestation of the common complaint that so much physiology, taxonomy, ecology, and diversity is ignored when microbial communities are described […]
