The Nine-Banded Armadillo In Texas and the South

Journal of Cultural Geography, 1981
Americans have contributed directly and indirectly to the relatively rapid spread of the nine-handed armadillo (Dasypus novemcinctus) in the United States. Curiosity about its bizarre appearance and growing commerce in live animals and armadillo “baskets” made from its bony carapace or shell have resulted in the transportation and release of this ...

Spermiogenesis in the Nine-Banded Armadillo

Proceedings, annual meeting, Electron Microscopy Society of America, 1973
The testes of mature armadillos were fixed by either perfusion or immersion. The morphology of the seminiferous tubules and the process of spermiogenesis were studied.The developing spermatids are generally oval in shape and contain a centrally placed nucleus.

The Nine-Banded Armadillo

1996
Order Edentata (Xenarthra), the “toothless” mammals, consists of only three families: armadillos, sloths, and anteaters. Edentata flourished in the Lower Tertiary Age (30 MYA), but only these three genera have survived. Until recently, there were a number of species with and without teeth that were confined to South America.

Morphology of the prostate gland in the nine-banded armadillo

Cells Tissues Organs, 1980
The prostate of the nine-banded armadillo is a compound tubulo-alveolar, bilobed gland situated on the ventral surface of the seminal vesicles. The two lobes, which may be connected by a narrow isthmus of tissue, are encapsulated by a thin layer of connective tissue and are located peripheral to the urethral musculature.

Myoglobin: Quantification in the nine-banded armadillo (Dasypus novemcintus)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976
1. 1. Myoglobin from the nine-banded armadillo (Dasypus novemcintus) was purified on Sephadex G-75. The absorption spectrum and extinction coefficients for HbCO and MbCO were determined between 520 and 590 nm and used to quantify myoglobin within the heart, diaphragm, thigh, triceps and gastrocnemis in six adults and one juvenile. 2. 2.

Determinants of Aggression in Nine-Banded Armadillos

Journal of Mammalogy, 1994
Potential 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, 1989
Cold 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, 2009
10 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.

Time Budgets of Wild Nine-Banded Armadillos

Southeastern Naturalist, 2009
Dasypus 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.
