A comparison of two N-irradiance interaction models of phytoplankton growth
two N-irradiance interaction models phytoplankton growth
font style='font-size:12px;'>
2014/6/10
The N-photoacclimation interaction models of Geider et al. (GM) and Flynn et al. (FM) are compared by tuning them to data from a light-shift experiment for a diatom. Both the original model constructs...
Coulometric carbon-based respiration rates and estimates of bacterioplankton growth efficiencies in Massachusetts Bay
Coulometric carbon-based respiration rates bacterioplankton growth efficiencies Massachusetts Bay

2014/6/9
Heterotrophic bacterioplankton production rates have been measured in many aquatic ecosystems over the last two decades, whereas measurements of bacterioplankton respiration rates have been scarce. Th...
Effects of mineral nutrients on the growth of bacterio- and phytoplankton in two southern reservoirs
mineral nutrients growth of bacteria phytoplankton two southern reservoirs
font style='font-size:12px;'>
2014/6/9
Nutrient limitation of bacterio- and phytoplankton was studied simultaneously in two warm-water lakes in the southern United States—Joe Pool Lake (JPL) and Eagle Mountain Lake (EML). Lakes were s...
Supplementation of cyanobacterial food with polyunsaturated fatty acids does not improve growth of Daphnia
cyanobacterial food polyunsaturated fatty acids does not improve growth of Daphnia
font style='font-size:12px;'>
2014/6/9
The hypothesis that the low food quality of nontoxic, ingestible cyanobacteria for Daphnia is due to the absence of long-chained polyunsaturated fatty acids (PUFAs) was tested. Synechococcus elongatus...
Effect of fluid shear and irradiance on population growth and cellular toxin content of the dinoflagellate Alexandrium fundyense

2014/6/9
The potential for in situ turbulence to inhibit dinoflagellate population growth has been demonstrated by experimentally exposing dinoflagellate cultures to quantified shear flow. However, despite int...
Phaeocystis globosa (Prymnesiophyceae) and the planktonic food web: Feeding, growth, and trophic interactions among grazers
Prymnesiophyceae Feeding, growth trophic interactions among grazers
font style='font-size:12px;'>
2014/5/30
The feeding and growth of copepods and heterotrophic protozoans when fed Phaeocystis globosa (Prymnesiophyceae) single cells were studied in the laboratory. The calanoid copepod Acartia tonsa fed on P...
Effects of dietary phosphorus deficiency on the abundance, phosphorus balance, and growth of Daphnia cucullata in three hypereutrophic Dutch lakes
dietary phosphorus defi ciency abundance phosphorus balance
font style='font-size:12px;'>
2014/5/30
We studied population dynamics, phosphorus balance, and individual growth to evaluate limitation of Daphnia
cucullata by dietary phosphorus (P) in three interconnected, hypereutrophic Dutch lakes. Co...
Effect of temperature on diatom volume, growth rate, and carbon and nitrogen content: Reconsidering some paradigms
iatom volume growth rate carbon
font style='font-size:12px;'>
2014/5/30
We examined the response of diatoms to naturally experienced temperatures and tested these hypotheses: (1)
diatoms follow the rule that organism size decreases with increasing temperature; (2) diatom...
Growth rates of large and small Southern Ocean diatoms in relation to availability of iron in natural seawater
Growth rates of large small Southern Ocean
font style='font-size:12px;'>
2014/5/30
Blooms of large diatoms dominate the CO2
drawdown and silicon cycle of the Southern Ocean in both the past
and present. The growth of these Antarctic diatoms is limited by availability of iron (and ...
Rapid estimation of in situ growth rates of Caridina nilotica (Crustacea: Decapoda) in Lake Victoria: Description and pilot application of a simple, field-compatible technique

font style='font-size:12px;'>
2014/6/9
A simple rapid approach to estimating in situ growth rates of Caridina nilotica (Roux), a small shrimp that plays a pivotal role in Lake Victoria's food web, is described. The approach, potentially ap...
