Ultrastructure and morphometry of ovarian follicles in the armadillo Chaetophractus villosus (Mammalia, Dasypodidae) [PDF]
Brazilian Journal of Biology, 2001 Ultrastructural and morphometric changes in oocyte and surrounding granulosa cells during armadillo follicular growth are described. Primordial, intermediary, early and late primary, secondary, tertiary and preovulatory Graafian follicles were found ...

Dasypus hybridus(Cingulata: Dasypodidae) [PDF]
Mammalian Species, 2016 Dasypus hybridus ([Desmarest, 1804][1]) is commonly known as the southern long-nosed armadillo. Like all armadillos, it bears a carapace of ossified dermal scutes covered by epidermal scales. This diurnal species mainly inhabits grasslands on humic soils in Argentina, Uruguay, Paraguay, and southern Brazil. D . hybridus is omnivorous with a tendency to

The burrow ofDasypus hybridus (Cingulata: Dasypodidae) [PDF]
Acta Theriologica, 2001 Dasypus hybridus (Desmarest, 1804) inhabits open fields in southern South America. Burrows of D. hybridus were cylindrical with a conical end. They had an entrance and a single tunnel without branches. Three locations of the burrows in the terrain were detected: in banks of dried waterways, near rocks, and in open field.

Dasypus kappleri (Cingulata: Dasypodidae) [PDF]
Mammalian Species, 2019 AbstractDasypus kappleri Krauss, 1862, commonly known as greater long-nosed armadillo, is the second largest extant armadillo and readily distinguishable by the prominent spurs on the hind legs. It is diurnal-nocturnal, solitary, and insectivorous. It is a semi-fossorial species ranging east of the Andes across the central lowlands of South America. It

Divergence Across Niche Dimensions Reveals Species' Ecological Roles. [PDF]
Ecol LettNatural history gaps hinder our understanding of species' ecological roles and their contributions to ecosystem processes. Using an integrative framework, we analysed multiple niche dimensions of co‐occurring xenarthran insectivores, revealing divergent trophic, spatial and temporal patterns that reflect distinct ecological roles. Our results challenge

Ecology and Evolution, Volume 13, Issue 12, December 2023., 2023 A robust minimum age tree shows post K–Pg Placentalia radiation, and subsequent extensive radiation connected to exponentially increased base substitution (mutation) rate including generation of Homo sapiens. This Neogene radiation may have been triggered by expansion of C4 grasses that decreased atmospheric CO2, resulting in global cooling and ...

Fleas and lesions in armadillo osteoderms
Journal of Anatomy, Volume 242, Issue 6, Page 1029-1036, June 2023., 2023 Study of lesions caused by flea's ‘bites’ in the bones on the backs of armadillos show that they are actually made by the host's own osteoclasts, not by the flea's own masticatory apparatus. Panels (a, c, e) are reconstructions from high‐contrast resolution X‐Ray Microtomography and (b, d, f) backscattered electron mode scanning electron microscopy ...

Spatiotemporal distributions of mammals occurring in an agro‐prairie ecosystem
Ecology, Volume 104, Issue 3, March 2023., 2023 Abstract Anthropogenic activities since the European colonization of the North American Great Plains have drastically altered landscape composition and configuration, subsequently affecting native biodiversity. These contemporary human‐modified landscapes may affect mammal species' distributions, diel activity patterns, habitat use, and interspecific ...
