The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]

, 2019
The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...

Comptes Rendus Palevol, 2017
Abstract Within the Late Neogene Glyptodontidae of the Pampean region of Argentina, “Urotherium antiquum” was described on the basis of some associated osteoderms of the dorsal carapace, which in addition include a partial skull and left hemimandible.

Numerous independent gains of daily torpor and hibernation across endotherms, linked with adaptation to diverse environments

Functional Ecology, Volume 39, Issue 3, Page 824-839, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many endotherms from diverse taxonomic groups can respond to environmental changes through torpor, that is, by greatly reducing their energy expenditure for up to 24 hours (daily torpor) or longer (hibernation).

Turbinal bones are still one of the last frontiers of the tetrapod skull: hypotheses, challenges and perspectives

Biological Reviews, Volume 99, Issue 6, Page 2304-2337, December 2024.
ABSTRACT Turbinals are bony or cartilaginous structures that are present in the nasal cavity of most tetrapods. They are involved in key functions such as olfaction, heat, and moisture conservation, as well as protection of the respiratory tract. Despite recent studies that challenged long‐standing hypotheses about their physiological and genomic ...

The gross reproductive morphology of the male Temminck's pangolin Smutsia temminckii (Smuts, 1832)

Anatomia, Histologia, Embryologia, Volume 53, Issue 4, July 2024.
Abstract The Temminck's pangolin (Smutsia temminckii) is one of eight pangolin species worldwide and the only pangolin present in southern Africa. Historically, pangolins have not been able to reproduce successfully in captivity and this may be in part due to the lack of knowledge and understanding with regards to the pangolin reproductive system ...

Sobre la presencia de un supuesto Haplodontheriinae (Mammalia, Toxodontidae) en el Pleistoceno tardío de la provincia de Corrientes (Argentina)

Revista Mexicana de Biodiversidad, 2012
En el extremo sur de América del Sur, se han postulado varias áreas que podrían haber actuado como reservorio de taxones supérstites, especialmente en el lapso Mioceno-Pleistoceno tardío (“Araucanense”-Lujanense).  Así, en el Pleistoceno tardío (ca.

Morphological disparity of mammalian limb bones throughout the Cenozoic: the role of biotic and abiotic factors

Palaeontology, Volume 67, Issue 4, July/August 2024.
Abstract Mammals exhibit ecology‐related diversity in long bone morphology, revealing an ample spectrum of adaptations both within and between clades. Their occupation of unique ecological niches in postcranial morphology is thought to have occurred at different chronological phases in relation to abiotic factors such as climate and biotic interactions
