Quantitative investigation of the annual pattern of follicular development in the nine-banded armadillo (Dasypus novemcinctus).
Mature, non-pregnant, female armadillos (Dasypus novemcinctus) were killed throughout the year (3-6/month, N = 54) and both ovaries were examined for follicular development. All normal and atretic follicles > 358 micrometers were counte. Total number of normal follicles remained constant from January to June but decreased by 50% in the remaining months except in October and November. Follicles ...
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 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...
متن کاملAxial orthogonal fiber reinforcement in the penis of the nine-banded armadillo (Dasypus novemcinctus).
Examination of histological sections from flaccid and artificially erected nine-banded armadillo (Dasypus novemcinctus) penises confirms that the mammalian corpus cavernosum is the first known biological hydrostat reinforced by collagen fibers arranged at 0 degree and 90 degrees to its long axis. The morphology of this axial orthogonal fiber array affects the mechanical behavior of mammalian pe...
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...
