The word "taxa" is correct in written English.
It is used in biological contexts to refer to groups of organisms classified together.
Example: "The study focused on various taxa found in the rainforest ecosystem."
Alternatives: "groups" or "categories".
Systematists (taxonomists) are scientists and generally do not nor should they consider the "value" of taxa in drawing their conclusions.Scott Steppan Tallahassee, FloridaSIR —To discuss species diversity and taxonomy in the context of monetary inflation is a bit like watching a bank burn and observing that at least the remaining currency is gaining value.
Genetics as applied in conservation biology provides a precise, dependable, and repeatable way to define taxa and identify differences that cannot be observed as variation in shape, proportion or color.
Some are associated with very wide distribution of certain taxa, such as the Monograptus uniformis, Pinacites jugleri, and Platyclymenia annulata events.
Taxonomists call such related species sister taxa, following the analogy that they are splits from their "parent" species.
If it was a new hominin lineage, the evolutionary implication was that as many as five hominin taxa may have shared the Late Pleistocene landscape.
This rearrangement had little support, however, and taxa that had been added to an expanding Salmoniformes, or Protacanthopterygii, were removed to other places in the bony fish classification scheme.
The matrix is scanned again for the next smallest distance, and the two new taxa (say, C and D) are clustered.
Some are associated with very wide distribution of certain taxa, such as the Monograptus uniformis, Pinacites jugleri, and Platyclymenia annulata.
Ironically, many of the most successful modern phyla (including the chordates, which encompass all vertebrates) are rare elements in Cambrian assemblages; phyla that include the arthropods and sponges contained the most numerically dominant taxa (taxonomic groups) during the Cambrian, and those were the taxa that became extinct.
There are seven basic categories, and each organism therefore belongs to at least seven taxa.
Shell microstructure and mineralogy evidence generally support paleontological conclusions that the class Bivalvia comprises six subclasses, recognizing, however, that some of these taxa may have more than one first ancestor (polyphyletic).
