Phosphorus in a ground-water contaminant plume discharging to Ashumet Pond, Cape Cod, Massachusetts, 1999 The discharge of a plume of sewagecontaminated ground water emanating from the Massachusetts Military Reservation to Ashumet Pond on Cape Cod, Massachusetts, has caused concern about excessive loading of nutrients, particularly phosphorus, to the pond. The U.S. Air Force is considering remedial actions to mitigate potentially adverse effects on the ecological characteristics of the pond from continued phosphorus loading. Concentrations as great as 3 milligrams per liter of dissolved phosphorus (as P) are in ground water near the pond‘s shoreline; concentrations greater than 5 milligrams per liter of phosphorus are in ground water farther upgradient. Temporary drive-point wells were used to collect water samples... Categories: Publication; Types: Citation

Ecological distribution and population physiology defined by proteomics in a natural microbial community A fundamental question in microbial ecology addresses how organisms regulate their metabolic activities within natural communities as environmental constraints and population structures change. Recent advances in molecular biology have allowed for investigation into the physiology of organisms within natural settings, opening the door to understanding microbial metabolic responses in situ. Here, we have examined how a diverse set of organisms from microbial biofilms alters their protein complements as environmental parameters change and as ecological succession occurs. We find that, when growing in newly formed biofilms, the dominant organism within these communities exhibits a metabolism focused on rapid growth,... Categories: Publication; Types: Citation

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
