Hydroxyl radical (•OH) is a highly reactive and unselective oxidant in atmospheric aquatic systems. Current understanding limits the role of DOM-produced •OH as an carbon cycling mainly to sunlit environments where produced photochemically, but recent laboratory study proposed sunlight-independent pathway which forms during oxidation reduced dissolved organic matter (DOM) iron. Here we demonstrate this non-photochemical for formation natural environments. Across gradient from dry upland wet...
Photochemical hydroxyl radical formation decreases with increasing water residence time in a system of lakes connected by streams the Arctic.
Fog supplies water and nutrients to systems ranging from coastal forests inland deserts. droplets can also contain bacterial fungal aerosols, but our understanding of fog biology is limited. Using metagenomic tools culturing, we provide a unique look at communities in two fog-dominated sites: Maine (USA) the Namib Desert (Namibia). Microbial both sites were diverse, distinct clear influenced by soil marine sources. contained Actinobacteria Firmicutes, commonly soil- air-associated phyla,...
Abstract Litter decomposition plays a central role in carbon cycling terrestrial ecosystems worldwide. In drylands, which cover 40% of the Earth's land surface, photodegradation and biotic driven by non‐rainfall moisture are important mechanisms litter decay, though studies have only recently begun examining interactions between these two processes. We describe novel priming mechanism decay cuticle plant increase absorption (fog, dew water vapor), supporting greater microbial decomposition....
All perennial plants harbor diverse endophytic fungal communities, but why they tolerate these complex asymptomatic symbioses is unknown. Using a multi-pronged approach, we conclusively found that dryland grass supports endophyte communities comprised predominantly of latent saprophytes can enhance localized nutrient recycling after senescence. A bunchgrass, Stipagrostis sabulicola , which persists along gradient extreme abiotic stress in the hyper-arid Namib Sand Sea, was focal point our...
Non-rainfall moisture (fog, dew, and water vapor; NRM) is an important driver of plant litter decomposition in grasslands, where it can contribute significantly to terrestrial carbon cycling. However, we still do not know whether microbial decomposers respond differently NRM rain, nor this response affects rates. To determine how local regimes influence decomposer communities their function, examined fungal on standing grass at NRM-dominated site a rain-dominated 75 km apart the hyper-arid...
Abstract. A new coastal background site has been established for observations of greenhouse gases (GHGs) in the central Namib Desert at Gobabeb, Namibia. The location was chosen to provide a data-poor region global sampling network GHGs. Semi-automated continuous measurements carbon dioxide, methane, nitrous oxide, monoxide, atmospheric oxygen, and basic meteorology are made height 21 m a.g.l., 50 km from coast northern border Sand Sea. Atmospheric oxygen is measured with differential fuel...
Bovine trichomoniasis is a venereal disease that causes substantial economic losses to the cattle industry worldwide. It has been endemic in USA since its discovery 1930s. The reasons for this long-lasting endemism are poorly understood. main objective of study was identify herd-level risk factors Wyoming beef cattle. A questionnaire sent all producers. overall response proportion 23.4 %. Questionnaires were returned from producers throughout state different geographical regions and with...
Abstract Wildlife diseases pose a substantial threat to the provisioning of ecosystem services. We use novel modeling approach study potential loss these services through imminent introduction chronic wasting disease (CWD) elk populations in Greater Yellowstone Ecosystem (GYE). A specific concern is that concentrating at feedgrounds may exacerbate spread CWD, whereas eliminating increase number on private ranchlands and transmission second disease, brucellosis, from cattle. To evaluate...
As cancer therapies increase in effectiveness and patients' life expectancies improve, balancing oncologic efficacy while reducing acute long-term cardiovascular toxicities has become of paramount importance. To address this pressing need, the Cardiology Oncology Innovation Network (COIN) was formed to bring together domain experts with overarching goal collaboratively investigating, applying, educating widely on various forms innovation improve quality healthcare patients undergoing...
Abstract. Historically, ecosystem models have treated rainfall as the primary moisture source driving litter decomposition. In many arid and semi-arid lands, however, non-rainfall (fog, dew, water vapor) plays a more important role in supporting microbial activity carbon turnover. To date though, we lack robust approach for modeling of We developed series simple decay with different sensitivity temperature functions to explicitly represent process. evaluate model performance, conducted...
