Taxon - Open Access .click

Nature, 1999
Phylogenies that include long, unbranched lineages can be difficult to reconstruct. This is because long-branch taxa (such as rapidly evolving species) may share character states by chance more often than more closely related taxa share derived character states through common ancestry1. Despite Kim's warning that added taxa can decrease accuracy2, some

The Taxon Concept: Is it Taxonic?

Psychological Reports, 2008
The question of whether the concept of a “taxon” (a nonarbitrary latent category) is itself categorical, or is a matter of degree, has lain dormant within taxometrics. I analyze the problem conceptually. Part of the meaning of “taxon,” I hold, goes beyond the manifest statistical properties of admixed probability distributions; any of certain forms of

Testing the dissociative taxon

Psychiatry Research, 2004
A dissociative taxon has been proposed by Waller et al. (1996) to help identify individuals experiencing pathological dissociation. We studied the frequency of taxon membership and tested its validity. A total of 276 students and 204 psychiatric inpatients completed the Dissociative Experiences Scale (DES).

A CLADISTIC TEST OF THE TAXON CYCLE AND TAXON PULSE HYPOTHESES

Cladistics, 1990
Abstract— A species' habitat preference is intcrpretablc both as a response to present‐day conditions and as a result of evolutionary response to historical conditions. The taxon cycle and taxon pulse have been proposed as hypotheses that allow prediction of patterns of habitat specialization within a lineage.
