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.

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 ...

Dasypus septemcinctus (Cingulata: Dasypodidae) [PDF]

Mammalian Species, 2020
AbstractDasypus septemcinctus Linnaeus, 1758, commonly called the seven-banded armadillo, is the smallest species of the genus Dasypus, with 6–7 movable bands and a flattened dorsal profile of the skull. It has the most southern distribution of the genus, with a latitudinal range from 0º to 39ºS, including Brazil, eastern Paraguay, Bolivia, Uruguay ...

Roadkill patterns in Latin American birds and mammals

Global Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022
Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...

Cabassous centralis(Cingulata: Dasypodidae) [PDF]

Mammalian Species, 2013
Cabassous centralis (northern naked-tailed armadillo) is a small armadillo with a slender tail. The distinctive tail has widely spaced, thin plates that are gray-pink in color. This fossorial armadillo occurs in diverse tropical habitats and has a distributional range from southern Mexico, through Central America, and into northern South America ...

Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?

Geo: Geography and Environment, Volume 9, Issue 2, July‐December 2022., 2022
A geographical and biological puzzle that has perplexed scientists since the late 1800s working in southern South America: why are there so few vertebrates on the island of Tierra del Fuego compared to the adjacent Patagonia mainland, including the absence of the ubiquitous Guanaco (Lama guanicoe), wild camelid of the south? An interdisciplinary search

The first fossil record of a bone assemblage accumulated by New World vultures (Gruta do Presépio, Holocene, southern Brazil)

Boreas, Volume 51, Issue 3, Page 684-697, July 2022., 2022
Here we present the first fossil record of a bone assemblage that could have been accumulated by New World vultures (Cathartidae). The bone remains were found in an archaeological rockshelter called Gruta do Presépio (GPR), located in the tropical rainforest environment of Santa Catarina State, southern Brazil, where groups of hunters and gatherers ...

Determinants of population persistence and abundance of terrestrial and arboreal vertebrates stranded in tropical forest land‐bridge islands

Conservation Biology, Volume 35, Issue 3, Page 870-883, June 2021., 2021
Abstract Megadams are among the key modern drivers of habitat and biodiversity loss in emerging economies. The Balbina Hydroelectric Dam of Central Brazilian Amazonia inundated 312,900 ha of primary forests and created approximately 3500 variable‐sized islands that still harbor vertebrate populations after nearly 3 decades after isolation. We estimated

Morphofunctional Space of the Forelimb in Caraguatypotherium munozi (Notoungulata; Mesotheriidae): Insights Into Wrist-Powered Digging. [PDF]

J Morphol
Caraguatypotherium munozi displays a distinctive morphofunctional configuration combining high wrist flexor leverage with reduced elbow mechanical advantage—traits consistent with wrist‐dominated scratch‐digging. Multivariate analyses place it outside the core morphospaces of extant locomotor groups.
