A large number of bands with different intensity were present, presumably reflecting the difference in abundance of different bacterial ribotypes.
Problems arise from 1) variation between similar subspecies, 2) genomic sequence similarity between different species, and 3) difference in abundance for species in a sample also affected by different sequencing depths for individual species.
Moraxella was found to be among the top ten most abundant genera in our population; however, the difference in abundance was not significant between the cases and controls.
This difference in abundance level may be due in part to the different cell culture models utilized in the experiments.
In an effort to determine the biological processes that were influenced by altered environmental conditions, proteins were considered differentially abundant if either there was 1) a 2-fold difference in abundance between treatment groups or 2) a q-value <0.10.
EST-SSRs were significantly more abundant in the 3′UTR fraction, while there was a non-significant difference in abundance between the 5′UTR and ORF fractions.
Of the 20 bird species analyzed, 13 showed a difference in abundance between at least two of the three treatments.
This is an area ripe for further investigation, in particular because our study indicates no significant difference in abundance of pollinators in these other orders.
SRS catch rates in FMAS were significantly higher than wild animal catch rates in open aquatic systems in Cambodia and Thailand, indicating an underlying difference in abundance.
A total of 79 up-regulated protein spots with a >2.0-fold difference in abundance on 2-D gels under sclareol stress conditions were collected for further identification.
In comparison to fish exposed to the EBR sediment, the only significant difference in abundance of transcripts of cyp1a was in livers from fish sampled after 2 days of exposure to ZE sediment.
