prokaryotic genome size and ssu rdna copy number estimation of microbial Relative Abundance from a mixed population
Microbial Ecology, 1999Co-Authors: Gary B Fogel, C R Collins, J Li, Clifford F BrunkAbstract:Determination of the Relative Abundance of a specific prokaryote in an environmental sample is of major interest in applied and environmental microbiology. Relative Abundance can be calculated using knowledge of SSU rDNA copy number, amount of SSU rDNA in the sample, and a weighted average estimate of the genome sizes for organisms in the original sample. By surveying the literature, we provide estimates of genome size and SSU rDNA copy number for 303 and 101 prokaryotes, respectively. This compilation can be used to make reasonable estimates for a wide range of organisms in the calculation of Relative Abundance. A statistical analysis suggests that no correlation exists between genome size and SSU rDNA copy number. A phylogenetic analysis is used to offer insights into the evolution of both genome size and SSU rDNA copy number.

conventional oil and natural gas infrastructure increases brown headed cowbird molothrus ater Relative Abundance and parasitism in mixed grass prairie
Royal Society Open Science, 2017Co-Authors: Jacy Bernathplaisted, Heather R Nenninger, Nicola KoperAbstract:The rapid expansion of oil and natural gas development across the Northern Great Plains has contributed to habitat fragmentation, which may facilitate brood parasitism of ground-nesting grassland songbird nests by brown-headed cowbirds ( Molothrus ater ), an obligate brood parasite, through the introduction of perches and anthropogenic edges. We tested this hypothesis by measuring brown-headed cowbird Relative Abundance and brood parasitism rates of Savannah sparrow ( Passerculus sandwichensis ) nests in relation to the presence of infrastructure features and proximity to potential perches and edge habitat. The presence of oil and natural gas infrastructure increased brown-headed cowbird Relative Abundance by a magnitude of four times, which resulted in four times greater brood parasitism rates at infrastructure sites. While the presence of infrastructure and the proximity to roads were influential in predicting brood parasitism rates, the proximity of perch sites was not. This suggests that brood parasitism associated with oil and natural gas infrastructure may result in additional pressures that reduce productivity of this declining grassland songbird.
