Written in bones: palaeoclimate histotaphonomic history inferred from a complete Megatherium skeleton preserved in the Atacama Desert

Palaeontology, Volume 68, Issue 4, July/August 2025.
Abstract A nearly complete and relatively well‐preserved skeleton of the giant ground sloth Megatherium sp. in the hyperarid core of the Atacama Desert reveals how climate related taphonomic processes drastically transformed these remains over time.

Middle Pleistocene revelations: unravelling taphonomic processes in mammals including Mesotherium cristatum (Mesotheriidae, Notoungulata), Corralito Site, Córdoba Province, Argentina

Palaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

The Promise and Perils of NGO‐Supported Science

Philosophy Compass, Volume 20, Issue 5, May 2025.
ABSTRACT Until recently, philosophers of science have largely focused their attention on academic and industry‐funded research, overlooking the contributions of nongovernmental organizations (NGOs) to science. Nevertheless, NGO‐supported science is highly significant both from a practical perspective (serving as a source of impactful research that can ...

Three‐dimensional geometric morphometric analyses of humerus ecomorphology: New perspectives for paleohabitat reconstruction in carnivorans and ungulates

The Anatomical Record, Volume 308, Issue 3, Page 946-974, March 2025.
Abstract Long bone ecomorphology has proven effective for paleohabitat reconstructions across a wide range of mammalian clades. Still, there is no comprehensive framework to allow interpretation of long bone morphological variation within and between different monophyletic groups.

Multitemporal Analysis of Potential Geographic Distribution of Lama Guanicoe

Revista Ciencia y Tecnología
The purpose of this research is focused on modeling the geographic distribution of Lama guanicoe in South America in two time periods, 2021 and 2070, using MaxEnt software to correlate the bioclimatic variables and calculate the change in the distribution area.

Diet of Andean Leaf‐Eared Mice (Phyllotis) Living at Extreme Elevations on Atacama Volcanoes: Insights From Metagenomics, DNA Metabarcoding, and Stable Isotopes

Ecology and Evolution, Volume 14, Issue 11, November 2024.
On the flanks of > 6000 m Andean volcanoes that tower over the Atacama Desert, leaf‐eared mice (Phyllotis vaccarum) live at extreme elevations that surpass known vegetation limits. We used a combination of metagenomics, DNA metabarcoding, and stable isotope analyses to investigate the diet of mice living in these extreme environments.

Sistema tegumentario del guanaco (Lama Guanicoe)

Ciencia Veterinaria, 2017
Samples of different cutaneous areas of mature gumps were studied, previousl y processed by means of technics for optic microscopy. The differential characteristics among the different areas have observed them in relation to the thickness of the skin in general, to the abundance of the annexed glands and follicles pilosos, and fundamentally to the ...

Zooarqueología, Lama guanicoe, y dinámica evolutiva del Chaco Serrano

Mundo de Antes, 2010
Este trabajo evalúa preliminarmente la sustentabilidad a lo largo del Holoceno de un sistema de subsistencia basado en la caza de Lama guanicoe. Se plantea que dadas las condiciones de aislamiento biogeográfico las poblaciones de estos animales en las Sierras de Córdoba serían sensibles a la predación humana y que una estrategia de subsistencia basada ...

Global Distribution of Alien Mammals Under Climate Change

Global Change Biology, Volume 30, Issue 11, November 2024.
Climate change will most likely reshape the global distribution of alien mammal species across zoogeographic realms. Although these species' potential to establish in new areas is projected to increase, their spread will probably be constrained by their dispersal ability and geographic barriers, particularly in insular ecosystems.
