The phrase "select upon" is not a commonly used expression in written English and cannot be found in a dictionary
It is likely a mistake and should be replaced with "select from" or "choose from". For example: I had to select from a list of 10 books which one I wanted to read.
A novel approach to improve animal and plant fitness is to artificially select upon microbiomes, thus engineering evolved microbiomes with specific effects on host fitness.
These commercial birds were raised in a homogenous environment and exhibited a large spread in pathological response, suggesting that a mechanism other than environment, genetic variation, is responsible for the resistant or susceptible phenotypes and is available to select upon.
If, in practice, breeding schemes wish to select upon GW-EBV that require frequent updating, then a more appropriate comparison is between frequently updated fBayesB estimates of marker effects and the use of 'old' MCMC based estimates of marker effects, where the GW-EBV of animals are calculated without updating the estimates of marker effects, because of computational constraints.
We call this engineering approach host-mediated microbiome selection, because this method selects upon microbial communities indirectly through the host and leverages host traits that evolved to influence microbiomes.
They are selected upon entry if their transcripts and placement exam scores are high enough.
Franz Roth's photographs of the dead bodies inside Lviv prisons were selected upon Hitler's personal orders and distributed to the American press via AP.
These values were selected upon conducting pre-experiments during system pre-commissioning.
The maximum progress was achieved by strategies that selected upon several markers flanking multiple QTL in each generation.
They indicate that bacteria carrying specific pathways and primarily carrying tmoA/xylM/xylE1 genotypes, are being selected upon BTEX contamination.
The ensemble tree was then selected upon which to base future predictions (Additional file 2: Figure S6, Additional file 4: Dataset S2).
In such cases a sample of auxiliary data can be selected, upon which the auxiliary variable totals and means can be estimated and used together with model predictions that link the auxiliary variables with the target variable.
