Book Description
Scientists strive to develop clear rules for naming and grouping living organisms. But taxonomy, the scientific study of biological classification and evolution, is often highly debated. Members of a species, the fundamental unit of taxonomy and evolution, share a common evolutionary history and a common evolutionary path to the future. Yet, it can be difficult to determine whether the evolutionary history or future of a population is sufficiently distinct to designate it as a unique species. A species is not a fixed entity â€" the relationship among the members of the same species is only a snapshot of a moment in time. Different populations of the same species can be in different stages in the process of species formation or dissolution. In some cases hybridization and introgression can create enormous challenges in interpreting data on genetic distinctions between groups. Hybridization is far more common in the evolutionary history of many species than previously recognized. As a result, the precise taxonomic status of an organism may be highly debated. This is the current case with the Mexican gray wolf (Canis lupus baileyi) and the red wolf (Canis rufus), and this report assesses the taxonomic status for each.

A Research Strategy to Examine the Taxonomy of the Red Wolf
Author: National Academies of Sciences, Engineering, and Medicine
Publisher: National Academies Press
ISBN: 0309681472
Category : Science
Languages : en
Pages : 139
Book Description
A Research Strategy to Examine the Taxonomy of the Red Wolf provides independent guidance about taxonomic research on the red wolf, Canis rufus. Building from the 2019 report Evaluating the Taxonomic Status of the Mexican Gray Wolf and the Red Wolf, this report reviews and ranks research applications to determine the taxonomy of wild canid populations in southern Louisiana and other relevant locations. The report then develops a research strategy to examine the evolutionary relationships between ancient red wolves, the extant managed red wolf populations, and the unidentified canid populations.

A Report on the Taxonomic Status and Distribution of the Red Wolf
Author: John L. Paradiso
Publisher:
ISBN:
Category : Coyote
Languages : en
Pages : 44
Book Description
Comparison of 213 skulls of Canis rufus with 214 C. lupus and 335 C. latrans indicate that the red wolf is a distinct species. Before human disruption of the environment, rufus, lups, and latrans maintained their distinct status, and available specimens show no evidence that the red wolf intergraded with either coyote or gray wolf. A series of 71 skulls shows a complete variation from typical rufus to typical latrans. Apparently modification and decline of the red wolf population led to the breakdown of isolation and the formation of a hybrid swarm that suggests possible interbreeding with the coyote. Specimens indicate that as red wolves were extirpated in eastern Texas and elsewhere, a hybrid swarm moved eastward to occupy the niche that was created. By 1969, the swarm spread throughout most of eastern Texas and moved into Louisiana. Pure red wolves continued to survive only in a limited area along the Gulf Coast from Brazoria Counties, Texas, and in Cameron Parish.
