The phrase "assignment of taxa" is correct and usable in written English.
It can be used in contexts related to biology, ecology, or taxonomy when discussing the categorization or classification of organisms.
Example: "The assignment of taxa in this study was based on genetic analysis and morphological characteristics."
Alternatives: "classification of taxa" or "designation of taxa".
We had to perform the analysis of soil macrofauna on the basis of trophic groups because low densities of single taxa did not allow for separate analyses (see Table S2 for the assignment of taxa to trophic groups).
Through the GUI interface, a taxonomy reference tree can be used to hierarchically collect taxa and simplify the assignment of taxa into groups, and phylogenetic trees can be visually inspected using ATV [ 18].
A justification for using this logarithmic normalization function is provided in section C of Additional File 1. Step D - assignment of taxa to sequences: The query sequence is associated to the taxon whose (normalized) proportion (within the set of closest genome fragments) exceeds a predetermined threshold value.
Our analyses were typically conducted at the family level because of the higher confidence in the assignment of taxa based on the sequencing reads; therefore, a significant change at the family level may reflect changes of multiple gut bacteria at genus and species levels.
In addition, to allow the possibility that stratigraphic assignment of fossil taxa might be incorrect, we relaxed the strict minimum divergence time calibration by using a normal distribution around the minimum date for a particular stratigraphic interval.
Even though the generic assignments of keratose taxa is problematic for many taxonomists and can only be achieved with histological sections and long experience, we have demonstrated that the standard CO1 barcoding fragment is suitable at this level, although more genera will need to undergo additional testing.
In *BEAST, the assignment of specimens to taxa must be given as a prior for the analysis.
However, due to the absence of representative sequences for diverse species in the public domain, taxonomic assignment of the lowest taxa (i.e., species) is a challenging task for MyTaxa.
The tblastn and blastx search results were loaded into MEGAN and applied the LCA algorithm to compute the assignment of reads to taxa and estimate the USP expressing taxonomical content of each metagenome.
While assignment to pre-determined taxa is an operation distinct from the description of taxa, assignment accuracy is related to the ability of the character system used as the basis of assignment to track organismal phylogeny (i.e. display a phylogenetic signal [ 14]).
Despite most systematists adhering to cladistics since Hennig [ 46], many "good" Lepidoptera taxa, including those within Sphingidae [ 17], lack reliable (private) morphological synapomorphies which would enable rapid assignment of species to higher taxa.
