Effects of land use, urbanization, and climate variability on coastal eutrophication in the Baltic Sea
land use urbanization climate variability coastal eutrophication in the Baltic Sea
2014/4/17
Sedimentary records of organic matter inputs (stable nitrogen isotopes [d15N], nitrogen [N], and carbon [C] content), phytoplankton abundance (pigments, stable carbon isotopes [d13C]), and community c...
Effects of fetch and dissolved organic carbon on epilimnion depth and light climate in small forest lakes in southern Sweden
ight climate epilimnion depth
2014/4/16
We sampled small (0.03 to 3.3 km2
surface area) forest lakes in southern Sweden during two summers to
investigate how concentration of dissolved organic carbon (DOC) and lake size influence epilimni...
Mixing and its effects on biogeochemistry in the persistently stratified, deep, tropical Lake Matano, Indonesia
persistently stratified deep tropical Lake
2014/4/16
In the . 590-m deep, tropical Lake Matano (Indonesia), stratification is characterized by weak thermal
gradients (, 2uC per 500 m) and weak salinity gradients (, 0.14% per 500 m). These gradients per...
Combined effects of food quality and temperature on somatic growth and reproduction of two freshwater cladocerans
Combined effects of food quality somatic growth
2014/4/18
We investigated the effect of food quality on somatic growth and reproduction of zooplankton at different
temperatures (12uC, 15uC, 20uC, and 25uC). Standardized growth experiments of two cladocerans...
Spatial variability of climate and land-use effects on lakes of the northern Great Plains
Spatial variability climate land-use on lakes of the northern Great Plains
2014/4/21
Evaluation of the effects of climate change and human activities on lakes requires improved understanding of how stressors interact and the degree to which individual sentinel lakes represent broad sp...
Hydrogeomorphic features mediate the effects of land use/cover on reservoir productivity and food webs
Hydrogeomorphic land use cover on reservoir productivity food webs
2014/4/18
Although effects of land use/cover on nutrient concentrations in aquaticsystems are well known, half or more of the variation in nutrient concentration remains unexplained by land use/cover alone. Hyd...
Effects of small-scale turbulence on copepods: The case of Oithona davisae
small-scale turbulence copepods Oithona davisae
2014/5/20
We report the effects of small-scale turbulence on the feeding rates of the marine copepod Oithona davisae. Laboratory experiments were conducted under a range of turbulence dissipation rates between ...
Effects of groundwater flux on open-channel estimates of stream metabolism
groundwater flux open-channel estimates stream metabolism
2014/5/26
The open-channel oxygen method can produce precise estimates of photosynthesis (P) and respiration (R) over a wide range of stream conditions. It is widely recognized that flux of groundwater contribu...
Biogeochemical effects of iron availability on primary producers in a shallow marine carbonate environment
iron availability primary producers shallow marine carbonate environment
2014/6/9
We completed a synoptic survey of iron, phosphorus, and sulfur concentrations in shallow marine carbonate sediments from south Florida. Total extracted iron concentrations typically were <50 μmol g-1 ...
