The quadrupeds of North America

The zoogeomorphic characteristics of burrows and burrowing by nine-banded armadillos (Dasypus novemcinctus)

“…are native to South America; one of these, the nine-banded armadillo (Dasypus novemcinctus), is also found in the U.S. (Taulman and Robbins, 1996;McDonough et al, 2000). This invasive species migrated north through Texas from South America via Central America and Mexico, in the early 1850s (Audubon and Bachman, 1854;Humphrey, 1974). A distribution map illustrating known populations of armadillos indicates that the species expanded into southern Alabama between the late 1940s and 1972, with a single colony present in southeastern Alabama in 1949 (Fitch et al, 1952;Humphrey, 1974).…”

Ontogenetic changes in the long bone microstructure in the nine-banded armadillo (Dasypus novemcinctus)

“…Nine-banded armadillos are a relatively new and yet common faunal element in the southern United States, emigrating northward from Central America into Texas in the mid nineteenth century [41–44]. Their range has continued to expand north through Tennessee, Nebraska, South Carolina, and individuals have been found as far north as South Dakota and Minnesota [42,45–49].…”

History of Ecological Sciences, Part 56: Ethology until 1973

“…His other son, Victor, handled publication of the Quadrupeds (30 parts with five plates each, collected as three volumes, 1845–53). Unfortunately, two editions that appeared in and omitted Bachman's name from their title pages.…”
