Determinants of Aggression in Nine-Banded Armadillos
Journal of Mammalogy, 1994Potential determinants of aggression in nine-banded armadillos, Dasypus novemcinctus , were identified by comparing the sex, age, and reproductive status of initiators and recipients of aggression in a marked population in southern Texas. Males and females were equally likely to initiate and receive aggression.

Total calorimetry and temperature regulation in the nine‐banded armadillo
Acta Physiologica Scandinavica, 1989Cold exposure in the nine‐banded armadillo causes vigorous shivering and a rise in core temperature (Te). The increase in metabolic rate and Te depends upon exposure temperature, but may be as much as six times and 3 °C respectively (Johansen 1961). These findings might indicate an insensitivity to Te, which is puzzling since internal temperature is ...

Attempt to Infect the Nine-Banded Armadillo with Treponema pallidum
International Archives of Allergy and Applied Immunology, 200910 nine-banded armadillos were infected by various routes with Treponema pallidum, Nichols strain. The animals did not demonstrate visible lesions but 4/7 animals responded with increasing titers of treponemal antibodies. Cardiolipin antibodies were not detected.

Dasypus novemcinctus (Nine-banded armadillo)
1967The last autosome shown, a small submetacentric element, has always large satellites, often bent back over the main portion of this chromosome.

Time Budgets of Wild Nine-Banded Armadillos
Southeastern Naturalist, 2009Dasypus novemcinctus (Nine-banded Armadillo) produces litters of genetically identical quadruplets and, because of this, has long been considered a potential model system for the study of kin selection. However, long-term fi eld studies have failed to reveal any obvious instances of kin-selected altruism in this species.

Transmission of Mycobacterium ulcerans to the nine-banded armadillo.
The American journal of tropical medicine and hygiene, 1999Animal models for Mycobacterium ulcerans infections (Buruli ulcer) include guinea pigs, rats, and mice, but each has limitations in replicating the spectrum of human disease. Here, 19 adult nine-banded armadillos were inoculated intradermally with M. ulcerans.

Improved caging for nine-banded armadillos.
Laboratory animal science, 1976Impact resistant polyethylene cages were evaluated in these laboratories as replacements for plywood boxes for housing nine-banded armadillos. They were found to be less expensive, easier to sanitize, and to require less than one-third as much floor space per animal as the boxes.

Scent Discrimination by Infant Nine-Banded Armadillos
Journal of Mammalogy, 1994We tested the scent-discrimination abilities of infant (i.e., young-of-the-year) nine-banded armadillos ( Dasypus novemcinctus ) in two-choice tests. The amount of time spent near and the number of touches (with the snout) directed at pads containing various odors were recorded.

Spermatogonia and the cycle of the seminiferous epithelium in the nine-banded armadillo
Cell and Tissue Research, 1977The cycle of the seminiferous epithelium of the nine-banded armadillo can be divided into ten stages. As in most mammals, only one stage is observed per tubular cross-section. The process of spermiogenesis can be divided into thirteen steps according to the development of the acrosomal system and the flagellum.

The salivary glands and salivary bladder of the nine‐banded armadillo
The Anatomical Record, 1963AbstractHistochemical studies of armadillo salivary glands reveal mucous acini as the predominant secretory unit of the submaxillary and parotid glands. The acidic carbohydrate moiety of the salivary mucin is mostly sialic acid since Vibrio cholera neuraminidase (sialidase) markedly reduces the alcian blue reaction in the acinar cells. Morphologically,
