The phrase "abundance difference" is not a standard expression in written English and may cause confusion.
It could be used in contexts discussing variations or disparities in abundance, but clarity may be lacking without additional context.
Example: "The abundance difference between the two species in the ecosystem highlights the impact of environmental changes."
Alternatives: "disparity in abundance" or "variation in abundance".
Mass spectral evidence of the different glycan structure has been reported previously [7], although the abundance difference of the two different types has not.
In order to accurately compare the relative abundance difference of P.acnes among different samples, human beta-actin was used as the internal reference.
Importantly, it can be surmised that, at least in the first stages following the integration event (before the amelioration process can start), exogenous sequences maintain their own peculiar compositional features [e.g. GC% and dinucleotide relative abundance difference ] that usually differ from the rest of the "new" hosting molecule; for this reason these sequences are often defined "atypical".
On the other hand, weighted UniFrac distance is most sensitive to detect change in abundant lineages since it uses absolute abundance difference in its definition.
Moreover, even within the Buthidae family, vast abundance difference can be observed in venom compositions between genus to genus, different species within a genus and individuals within a species[ 10- 12].
Water mass also affected the species abundance difference, along with substrate (R2adj = 0.27) (Table 1.).
The cause of discrepancy between previous studies was proposed to be due to relative abundance differences of different miR399 members in the samples [ 45].
To determine proteins showing significant abundance differences between the different subject groups, mean and standard deviation for each ratio was calculated across all matched MS/MS spectra, and used to determine proteins showing significant differences in abundance between the two groups.
Four of these ORs showed both high sequence divergence and abundance differences, while the remaining genes differed in either sequence or abundance.
(iii) Different defect types can be studied and abundance differences can be investigated.
Messenger RNA transcript abundance did not reliably predict protein abundance differences between tumours.
