Neuronal calcium sensor-1 enhancement of InsP3 receptor activity is inhibited by therapeutic levels of lithium
(American Society for Clinical Investigation, 2006-06)
Regulation and dysregulation of intracellular calcium (Ca2+) signaling via the inositol 1,4,5-trisphosphate receptor (InsP3R) has been linked to many cellular processes and pathological conditions. In the present study, ...
Processing arctic eddy-flux data using a simple carbon-exchange model embedded in the ensemble Kalman filter
(Ecological Society of America, 2010-07)
Continuous time-series estimates of net ecosystem carbon exchange (NEE) are routinely made using eddy covariance techniques. Identifying and compensating for errors in the NEE time series can be automated using a signal ...
Burn severity influences postfire CO2 exchange in Arctic tundra
(Ecological Society of America, 2011-03)
Burned landscapes present several challenges to quantifying landscape carbon balance. Fire scars are composed of a mosaic of patches that differ in burn severity, which may influence postfire carbon budgets through damage ...
N budgets and aquatic uptake in the Ipswich River basin, northeastern Massachusetts
(American Geophysical Union, 2004-11-05)
We calculated N budgets and conducted nutrient uptake experiments to evaluate the fate of N in the aquatic environment of the Ipswich River basin, northeastern Massachusetts. A mass balance indicates that the basin retains ...
Correction to “Importance of carbon-nitrogen interactions and ozone on ecosystem hydrology during the 21st century”
(American Geophysical Union, 2009-08-22)
Baleen whales are not important as prey for killer whales Orcinus orca in high-latitude regions
Certain populations of killer whales Orcinus orca feed primarily or exclusively on marine mammals. However, whether or not baleen whales represent an important prey source for killer whales is debatable. A hypothesis by ...
Modeling coupled biogeochemical cycles
(Ecological Society of America, 2011-02)
Organisms require about 30 essential elements to sustain life. The cycles of these elements are coupled to one another through the specific physiological requirements of the organisms. Here, I contrast several approaches ...
Suction-based propulsion as a basis for efficient animal swimming
(Nature Publishing Group, 2015-11-03)
A central and long-standing tenet in the conceptualization of animal swimming is the idea that propulsive thrust is generated by pushing the surrounding water rearward. Inherent in this perspective is the assumption that ...
Testing isosource : stable isotope analysis of a tropical fishery with diverse organic matter sources
(Ecological Society of America, 2006-02)
We sampled consumers and organic matter sources (mangrove litter, freshwater swamp-forest litter, seagrasses, seagrass epiphytes, and marine particulate organic matter [MPOM]) from four estuaries on Kosrae, Federated States ...
Envisioning a marine biodiversity observation network
(University of California Press, 2013-05)
Humans depend on diverse ocean ecosystems for food, jobs, and sustained well-being, yet many stressors threaten marine life. Extensive research has demonstrated that maintaining biodiversity promotes ocean health and service ...
