Microevolution in time and space: SNP analysis of historical DNA reveals dynamic signatures of selection in Atlantic cod
fi sheries-induced evolution Gadus morhua genome scan
2015/12/11
Little is known about how quickly natural populations adapt to changes in their environment and how temporal and spatial variation in selection pressures interact to shape
patterns of genetic diversi...
Algal–bacterial competition for phosphorus from dissolved DNA, ATP, and orthophosphate in a mesocosm experiment
Algal– bacterial competition phosphorus dissolved DNA ATP orthophosphate a mesocosm experiment
2014/4/22
We measured the turnover of phosphorus (P) from radioactive-labeled dissolved deoxyribonucleic acid (dDNA), adenosine triphosphate (ATP), and orthophosphate, and the partitioning of P from these sourc...
Early diagenesis and trophic role of extracellular DNA in different benthic ecosystems
Early diagenesis extracellular DNA different benthic ecosystems
2014/4/22
To provide new insights into the early diagenesis of extracellular deoxyribonucleic acid (DNA) and its relevance in trophodynamic processes, we collected sediment samples from a variety of coastal and...
Viral infection plays a key role in extracellular DNA dynamics in marine anoxic systems
Viral infection plays a key role extracellular DNA dynamics marine anoxic systems
2014/4/23
To investigate the role of viruses in extracellular DNA production through cell lysis, we selected two systems where viruses are expected to be the main component controlling prokaryote dynamics. Thes...
Associations among ribosomal (r)DNA intergenic spacer length, growth rate, and C : N : P stoichiometry in the genus Daphnia
Associations growth rate
2014/5/16
The growth rate hypothesis (GRH) proposes that variation in organismal C : N : P ratios is associated
with growth rate due to differential allocation to P-rich ribosomal RNA to support growth. A furt...
Quantification, base composition, and fate of extracellular DNA in marine sediments
Quantification, base composition fate of extracellular DNA marine sediments
2014/5/27
The discovery of high concentrations of DNA in marine sediments unaccounted for by living biomass suggests the presence of a large fraction of extracellular DNA, which might play an important role in ...
The influence of food quality (P:C ratio) on RNA:DNA ratio and somatic growth rate of Daphnia
The influence of food quality P:C ratio RNA:DNA ratio somatic growth rate of Daphnia
2014/5/26
Growth experiments with juvenile Daphnia galeata were performed to investigate how fast their RNA:DNA ratio responds to changes in food quality, the relationship between RNA:DNA ratio and somatic grow...
