Divergence Across Niche Dimensions Reveals Species' Ecological Roles. [PDF]

Ecol Lett
Natural 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

Osteoderm microstructure of Riostegotherium yanei, the oldest Xenarthra [PDF]

Anais da Academia Brasileira de Ciências, 2019
Abstract: Riostegotherium yanei from the Itaboraí Basin, Brazil, is the oldest known Xenarthra. This paper aims to describe the internal morphology of the osteoderms of Riostegotherium yanei from the perspective of histology and micro-CT approaches, expanding the available data on cingulate osteoderm microstructure. Seven osteoderms of R.

Genome Sizes in Afrotheria, Xenarthra, Euarchontoglires, and Laurasiatheria [PDF]

Journal of Heredity, 2005
Topical literature and Web site databases provide genome sizes for approximately 4,000 animal species, invertebrates and vertebrates, 330 of which are mammals. We provide the genome size for 67 mammalian species, including 51 never reported before. Knowledge of genome size facilitates sequencing projects.

Primer registro de Scelidotheriinae Ameghino (Xenartha, Mylodontidae) del Piso/Edad Chasiquense (Mioceno tardío) de la Argentina [PDF]

, 2014
The subfamily Scelidotheriinae constitutes a group of mylodontids widely represented in the Quaternary of South America; however, the fossil record of the Neogene taxa is still scarce. In the present paper, a new specimen of this subfamily, corresponding

Revisión del género Panochthus (Xenarthra, Glyptodontidae)

Revista del Museo de La Plata, 2017
All the species of the genus Panochthus are reviewed. This taxon is one of the most important glyptodontid genus of the Pleistocene of Argentina because of its high frequency in the Ensenadan, Bonaerian and Lujanian units, as well as because of its wide geographical distribution that spans from the Santa Cruz province to the northern Argentina.

Arthritis in a Glyptodont (Mammalia, Xenarthra, Cingulata)

PLoS ONE, 2014
Arthritic lesions have been frequently diagnosed in the fossil record, with spondyloarthropathy (a type of erosive and pan-mammalian arthritis) being one of the most common types described to date for mammals, though not restricted to this group. Here, we identify spondyloarthropathy in fossil bones from the late Pleistocene in Brazil assignable to a ...
