Records of Nine-Banded Armadillos, Dasypus novemcinctus, in Illinois
The nine-banded armadillo, Dasypus novemcinctus, has been expanding its range in the United State since the mid-1800s. There had been sporadic reports of this species in Illinois prior to 1990. I conducted a mail survey in 2003 of individuals knowledgeable about the fauna of southern Illinois to investigate the possible expansion of the armadillo into the state. I also sent questionnaires to an...
متن کاملQuantitative investigation of the annual pattern of follicular development in the nine-banded armadillo (Dasypus novemcinctus).

All normal and atretic follicles > 358 micrometers were counte.

متن کاملExpansion of the tunica albuginea during penile inflation in the nine-banded armadillo (Dasypus novemcinctus).
Artificial inflation of corpora cavernosa from the nine-banded armadillo (Dasypus novemcinctus) showed that the expansion of the tunica albuginea during erection increases both components of flexural stiffness: the second moment of area and Young's modulus of elasticity. Folded tissue and crimped collagen fibers in the tunica albuginea permit its expansion during erection. As the tunica albugin...
متن کاملVertebral bending mechanics and xenarthrous morphology in the nine-banded armadillo (Dasypus novemcinctus).
The vertebral column has evolved to accommodate the broad range of locomotor pressures found across vertebrate lineages. Xenarthran (armadillos, sloths and anteaters) vertebral columns are characterized by xenarthrous articulations, novel intervertebral articulations located in the posterior trunk that are hypothesized to stiffen the vertebral column to facilitate digging. To determine the degr...
متن کاملIdentification of an Attractant for the Nine-Banded Armadillo, Dasypus novemcinctus
The nine-banded armadillo (Dasypus novemcinctus) is considered by many to be one of the greatest nuisance wildlife species in the Southeastern United States. Management is difficult because no repellents, toxicants, or fumigants are currently registered for this species; exclusion is laborious because armadillos are adept burrowers; and no effective trapping attractants have been identified. If...
