Organisms of the Nitrogen Cycle Under Extreme Conditions: Low Temperature, Salinity, pH Value and Water StressThis chapter provides a general understanding of the importance of the denitrification and other reactions of the N-cycle in these environments to global ecology, the principles governing their...

N2-fixation in the SPG may account for the production of 8–20% of global oceanic new nitrogen. Interestingly, comparable 15N2-fixation rates were measured under light and dark conditions. Meanwhile, phylogenetic analyses for the functional gene biomarker nifH and its transcripts could not detect ...
How many marine organisms are in the Bahamas? How do marine organisms extract the dissolved oxygen from seawater? How many species are in the marine biome? What is the percent of water found in marine organisms? How is nitrogen circulated amongst marine organisms? How many marine species are...
Understanding energy and material fluxes through ecosystems is central to many questions in global change biology and ecology. Ecosystem respiration is a critical component of the carbon cycle and might be important in regulating biosphere response to global climate change. Here we derive a general mod...
cycle. Therefore, maintenance of precise timing for behavioral and metabolic activities should be one of the most essential functions of circadian clocks, especially for organisms living in natural environments where light, temperature, humidity, food, predators and competitors fluctuate with time of the...

Ultimately, the reduction of multiple terminal electron accepting use of proteogenomic data to infer nitrogen cycle processes (Roychoudhury and Merret, 2006). Our processes highlights the complementary value of genomic analyses suggest that the sulfate reduction this approach when compared with geochemical...
