Nitrification in Mono Lake, California: Activity and community composition during contrasting hydrological regimes
Nitrification in Mono Lake California Activity and community composition contrasting hydrological regimes
2014/4/21
Rates of nitrification, geochemical variables, and the associated ammonia oxidizer microbial community were investigated in the water column of Mono Lake, California, between August 2002 and August 20...
Physical, chemical, and microbial regimes in an anoxic fjord (Nitinat Lake)
Physical chemical microbial regimes anoxic fjord
2014/4/22
New observations of physical, biological, and chemical parameters were obtained between July 2003 and February 2005 in Nitinat Lake, British Columbia, a permanently anoxic seawater fjord. These observ...
Simulated light regimes affect feeding and metabolism of Antarctic krill, Euphausia superba
light regimes affect feeding metabolism of Antarctic krill Euphausia superba
2014/4/22
The effect of different light regimes on physiological parameters (feeding activity, oxygen consumption, and activity of the metabolic enzyme malate dehydrogenase [MDH]) of Antarctic krill, Euphausia ...
Effects of water color on predation regimes and zooplankton assemblages in freshwater lakes
water color predatory regimes zooplankton assemblages freshwater lakes
2014/5/21
Northern temperate lakes often have high water color because of high concentrations of dissolved organic carbon (DOC). Altered light, temperature, and oxygen profiles in these brown-water lakes should...
Stage-specific mortality of Calanus spp. under different predation regimes
Stage-specific mortality Calanus spp. different predation regimes
2014/5/27
We have applied the population surface method to estimate the mortality rates of eggs, nauplii, and copepodids of Calanus spp. in two Norwegian fjords with contrasting predator guilds. Efforts were co...
Iron and macronutrients in California coastal upwelling regimes: Implications for diatom blooms
Iron and macronutrients California coastal upwelling regimes diatom blooms
2014/6/10
The supply of iron, relative to that of the macronutrients nitrate, phosphate, and silicic acid, plays a critical role in allowing extensive diatom blooms to develop in coastal upwelling regimes. The ...
Response of marine bacterial community composition to iron additions in three iron-limited regimes
marine bacterial community iron additions three iron-limited regimes
2014/6/9
In high-nutrient low-chlorophyll (HNLC) regimes, iron additions consistently result in primary productivity increases, and the phytoplankton community shifts from small species toward large diatoms. H...
