The phrase "abundance variation" is correct and usable in written English.
It can be used in contexts discussing changes or differences in levels of abundance, such as in ecology, economics, or statistics.
Example: "The study focused on the abundance variation of different species in the ecosystem over the past decade."
Alternatives: "variation in abundance" or "changes in abundance".
We report the microbial diversity, abundance variation and interaction patterns of the gastric microbiota of Indian patients with H. pylori infection and present a comparison of the same with the gastric microbial ecology in samples from different geographic regions.
For 68 bacterial genera carrying DRs, abundance variation of 32 genera was significantly lower in health people than in patients (Fig. S3).
To further investigate the primary cause of significant differences in CRISPR elements between periodontally diseased patients and healthy people, we conducted F-test to compare the abundance variation of each DRs and spacers.
Thus, it may be important to account for the potential contributions by these two gases due to the abundance variation of SO2 or cloud-top altitude variations, which can impact the CO2 contribution to the brightness temperature sensed by LIR. Figure 19 shows two sample images taken from the LIR camera.
"If the methane abundance variation has a definite seasonal variation, then it might suggest some sort of biological origin, although there are also some geological mechanisms which might respond to seasonal change," Chizek said.
This demonstrates that although CH abundance variation is high, it is nonetheless strongly constrained by chemistry.
We also demonstrate that the E. coli chemotaxis pathway is particularly robust to abundance variations of the motor protein FliM.
We just need to learn to recognize a few different kinds of these foraminifera so that we can work with their abundance variations in the seabed sediment record and read the history of the north Atlantic climatic system.
The lack of Na and strong K is the first indication of a sub-solar Na/K abundance ratio in a planetary atmosphere (ln[Na/K]=−3.3±2.8), which could potentially be explained by Na condensation on the planet's night side, or primordial abundance variations.
Coronae of cool stars are ideal laboratories to investigate hot, magnetically trapped plasma and its dynamics, such as coronal mass motions, temperature and emission measure changes during flares, electron densities in various coronal temperature regimes, optical depth effects, coronal abundances and abundance variations, etc.
Strong abundance variations are commonly observed in TD-GC-MS (J.
