Algal biomass accrual in relation to nutrient availability ~ Nutrient limitation operates across a broad variety of ecosystems, occurring when a nutrient is in short supply relative to cellular growth requirements (Dodds et al. 2002).Primary productivity and algal biomass accrual are typically higher in response to greater nutrient availability (Lohman et al. 1991).Nutrients also influence algal community structure, and individual species often have .

Nutrient control of algal growth in estuarine waters ~ During periods of high nutrient availability and low light, how- ever, all plants take up nutrients in excess of imme- diate demands, building up internal stores which can be utilized during subsequent periods of low nutrient availability and high light (Chapman & Craigie 1977, Zimmerman & Kremer 1986, Pedersen & Borum 1993).

Algal Periphyton Growth on Nutrient‐Diffusing Substrates ~ Differences in nutrient limitation for dominant species within an algal periphyton community were determined using additions of N and P supplied by nutrient—diffusing artificial substrates. Sealed clay flowerpots were filled with 2% agar and one of nine nutrient treatments (all combinations of K 2 HPO 4 at 0.0, 0.05, and 0.5 mol/L with NaNO 3 .
Determination of Nutrient Limiting Maximum Algal Biomass ~ utility for assessing nutrient limitation under certain conditions, the results of such tests are often confusing in that in mixed populations of algae, a non-nitrogen-fixing algal growth may be limited by nitrogen while in the same water another alga having the ability to fix atmospheric
Nutrient sources and composition of recent algal blooms ~ Water in JDQ, XZK and LT Lake during blooms had similar concentration ranges of DO and COD MN; however, nutrient concentrations varied . The range of TP concentration were around 0.02–1.10 mg L −1 in XZK, while the corresponding values were about 0.03–0.99 mg L −1 for JDQ, and 0.01–0.20 mg L −1 for LT Lake.
NUTRIENT LIMITATION AND ALGAL GROWTH ABOVE AND BELOW THE MAPLE ~ nutrient limitation. In order to determine any potential future changes to downstream communities, two sites above the dam (East and West Branches) and one site below the dam (Main Branch) will be monitored (fig. 1). Differences in limiting nutrient will be determined via

Nutrient Limitation of Algal Standing Crops in Shallow ~ Nutrient Limitation of Algal Standing Crops in Shallow Prairie Lakes. Lois Haertel. . The correlations were greater in the deeper lake. Phosphorous was positively correlated during one season in the deeper lake, never in the shallower lake. Multiple regression analyses using concentrations of nitrate, ammonia, and orthophosphate as dependent .
Increasing nutrients, changes in algal biomass, and large ~ In contrast, depth -integrated algal biomass (chlorophyll . a) shows a significant steady decline from 1999 to 2011 (Fig. 3C). These seemingly opposing observations - high algal biomass and Noctiluca at the surface and decreasing biomass below the surface - could be clues to a shifting food - web structure and nutrient fluxes in Puget Sound.
Probabilistically assessing the role of nutrient loading ~ Introduction. The implementation of primarily point-source phosphorus (P) reduction programs under the 1978 Great Lakes Water Quality Agreement (GLWQA) was followed by a decrease in the occurrence of algal blooms and hypoxia in Lake Erie during the 1980s (DePinto etal., 1986, Makarewicz etal., 1989).However, harmful algal blooms (HABs) have increased in frequency and intensity since the mid .

The impact of nutrient availability and algal community on carbon isotope fractionation in Crystal Lakes, Clark County, Ohio. Crystal Lakes are a group of four interconnected lakes, located in southwestern Clark County, Ohio.

"Algal growth potential and nutrient limitation in the Las ~ Algal bioassays were conducted to determine algal growth potential (AGP) and nutrient limitation of the Las Vegas (LV) Bay of Lake Mead using the standard test organism Selenastrum capricornutum and the Lake phytoplankton. Results for the current nutrient levels in the LV Bay revealed that the AGP of the LV Bay waters, measured by the maximum specific growth rates is limited by phosphorus (P).
Algal Periphyton Growth on Nutrient-Diffusing Substrates ~ to describe overall algal growth and to identify those indicator species that became dominant in response to particular nutrient additions. The method is thus an in situ bioassay of nutrient limitation using periphyton. Our data were further used in an evaluation of Tilman's (1982) model predicting growth response to essential resources.
Relation of Nutrient Concentrations, Nutrient Loading, and ~ Nutrient enrichment has led to excessive algal growth in Kabetogama Lake, Voyageurs National Park, northern Min-nesota. Water- and sediment-quality data were collected during 2008–09 to assess internal and external nutrient loading. Data collection was focused in Kabetogama Lake and its inflows,
The Influence of Nutrients and Physical Habitat in ~ Introduction. Nutrients, particularly nitrogen and phosphorus, have long been identified as a major water-quality issue because of their role in the eutrophication of streams, lakes, and coastal waters (Carpenter and others 1998; U.S. Environmental Protection Agency [EPA] 1998; NRC 2000).The U.S. Environmental Protection Agency (U.S. EPA 2000) cited nutrients as the third leading cause of .

The present study is concerned with locating the sources and
Nutrient and Sediment Reductions from Algal Flow-way ~ algal biomass. This algal growth is strongly dependent upon temperature and light. The algae are regularly harvested and the accumulated algal biomass can be used for biofuels, compost, omega-3 oils, fertilizer, soil amendments, or animal feed.

Nutrient and algal responses to winterkilled fish-derived ~ Fishes inhabiting shallow, glacial lakes of the Prairie Pothole Region in the United States and Canada periodically experience hypoxia in severe winters that can lead to extensive fish mortality resulting in high biomasses of dead fish. However, the role of carcass-derived nutrient subsidies in shallow, eutrophic lakes translocated to pelagic primary producers is not well documented.
