Metal accumulation in wild nine-banded armadillos

Ecotoxicology, 2013
Nine-banded armadillos (Dasypus novemcinctus) are widespread and abundant New World mammals with a lifestyle that entails prolonged, intimate contact with soils. Thus, armadillos would seem a promising candidate as a sentinel species to monitor chemical contamination in terrestrial ecosystems.

Fibroma in a Nine-banded armadillo (Dasypus novemcingtus)

Journal of Comparative Pathology, 1983
An adult male Nine-banded armadillo (Dasypus nonemcintus) had a large tumour between the first and second phalanges of the right fore-foot. The tumour was of dermal origin, consisted of dense interlacing bundles of collagen, and contained numerous fibroblasts with elongate nuclei and sparse cytoplasm.

Epithalamus of the nine-banded armadillo, Dasypus novemcinctus

Comparative Biochemistry and Physiology Part A: Physiology, 1986
The epithalamus of embryonic, neonatal and adult nine-banded armadillo (Dasypus novemcinctus) was examined for evidence of pineal-like tissue. The evagination of the diencephalic roof (the anlage of the epiphysis) was not found in any embryonic specimens.

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.

Influences on Vigilance in Nine‐banded Armadillos

Ethology, 1995
AbstractFunctional aspects of vigilance in nine‐banded armadillos (Edentata: Dasypus novemcinctus) were investigated. Data on solitary individuals revealed few age or sex differences in time spent vigilant. However, vigilance increased in most social contexts and was highest during intraspecific agonistic encounters.

Scent Discrimination by Infant Nine-Banded Armadillos

Journal of Mammalogy, 1994
We 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.

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.

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.
