Limnology of tundra ponds, Barrow, Alaska
(Dowden, Hutchinson & Ross, 1980)
This book is a report of investigations of several small ponds on the arctic tundra near Barrow, Alaska. The main study, which ran from 1971 through 1973, was funded from three sources: The National Science Foundation, ...
The savory swimmer swims north : a northern range extension of the blue crab Callinectes sapidus?
Worldwide, climate-change is shifting species distributions poleward. Here I present recent (2012-2014) observations of the blue crab, Callinectes sapidus, in the Gulf of Maine (GoM), north of its historical range of Cape ...
Satellite remote sensing data can be used to model marine microbial metabolite turnover
(Nature Publishing Group, 2014-07-29)
Sampling ecosystems, even at a local scale, at the temporal and spatial resolution necessary to capture natural variability in microbial communities are prohibitively expensive. We extrapolated marine surface microbial ...
Land carbon sequestration within the conterminous United States : regional- and state-level analyses
(John Wiley & Sons, 2015-02-28)
A quantitative understanding of the rate at which land ecosystems are sequestering or losing carbon at national-, regional-, and state-level scales is needed to develop policies to mitigate climate change. In this study, ...
Sewage reflects the microbiomes of human populations
(American Society for Microbiology, 2015-02-24)
Molecular characterizations of the gut microbiome from individual human stool samples have identified community patterns that correlate with age, disease, diet, and other human characteristics, but resources for marker ...
Farm management, not soil microbial diversity, controls nutrient loss from smallholder tropical agriculture
(Frontiers Media, 2015-03-04)
Tropical smallholder agriculture is undergoing rapid transformation in nutrient cycling pathways as international development efforts strongly promote greater use of mineral fertilizers to increase crop yields. These changes ...
Unique patterns of transcript and miRNA expression in the South American strong voltage electric eel (Electrophorus electricus)
(BioMed Central, 2015-03-26)
With its unique ability to produce high-voltage electric discharges in excess of 600 volts, the South American strong voltage electric eel (Electrophorus electricus) has played an important role in the history of science. ...
Ecological succession and viability of human-associated microbiota on restroom surfaces
Human-associated bacteria dominate the built environment (BE). Following decontamination of floors, toilet seats, and soap dispensers in 4 public restrooms, in situ bacterial communities were characterized hourly, daily, ...
Biogeography and ecology of the rare and abundant microbial lineages in deep-sea hydrothermal vents
Environmental gradients generate countless ecological niches in deep-sea hydrothermal vent systems, which foster diverse microbial communities. The majority of distinct microbial lineages in these communities occur in ...
