You can use it when referring to extra categories or classifications that complement existing ones.
Example: "The report includes additional groupings of data to provide a more comprehensive analysis."
Alternatives: "extra categories" or "supplementary classifications".
Within several arms, homologies were also detected to multiple ancestral linkage groups (e.g., RT6p, RT7q, RT9p, RT12p, RT17p, RT24p and their respective Atlantic salmon homologues), and single-marker assignments to additional groupings are also evident, suggesting certain linkage group arms in the salmonid genome may even be more mosaic than currently depicted.
Moreover, additional groupings (K = 4) divided inland populations and three coastal population groups (FCT = 0.709, P< 0.001).
Additional groupings have been found that are less certain.
Additional groupings also based on ecological knowledge of the species were further tested, namely: birds up to 5y old (noted as 1 5 in models), birds from 6 to 8y old, and individuals being >8y old.
There are additional groupings of homeobox genes outside the ANTP class.
This process was repeated by the second author until no additional groupings, and no new relevant redundancies, were found.
Cluster 3 comprised 29 strains and may contain additional strain groupings, but further phylogenetic delineation of this cluster could not be done with sufficient confidence.
Spearman correlation coefficients ranged from 0.57 (mono- ortho substituted and group 1b) to 0.98 (di- ortho substituted and group 3) between PCB groupings (Additional file 1 Table S5a).
All isolates were identical on MLVA-25 and grouped into the A4 (Vollum-like) cluster using the MLVA-25 nomenclature and the genotype 57 group using the Lista et al. [ 24] groupings (Additional file 4: Fig. S2).
In a neighbour-joining tree, the sequences from these two areas tended to form groups of their own, otherwise there were no clear geographical groupings (Additional file 3).
The 183 identified targets from our degradome analyses belonged to 57 different annotation groupings (Additional file 1).
