Global Ecology and Biogeography, Volume 31, Issue 9, Page 1810-1823, September 2022., 2022 Abstract Aim Human activities are causing massive increases in extinction rates but might also lead to drastic increases in speciation rates; for example, after human‐mediated spread of species to otherwise unreachable landmasses. The long‐term net anthropogenic effects on biodiversity therefore remain uncertain.

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 Miocene: The Future of the Past
Paleoceanography and Paleoclimatology, Volume 36, Issue 4, April 2021., 2021 Abstract The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative to today. Continental configurations and mountain topography transitioned toward modern conditions, and many flora and fauna evolved into the same taxa that exist today.

Out of Africa: A New Afrotheria Lineage Rises From Extinct South American Mammals
Frontiers in Ecology and Evolution, 2021 The South American native ungulates (SANUs) are usually overlooked in Eutherian phylogenetic studies. In the rare studies where they were included, the diversity of SANUs was underrated, keeping their evolutionary history poorly known.

Publicación Electrónica de la Asociación Paleontológica Argentina, 2017 South American native ungulates include several extinct lineages that evolved within the context of South American Cenozoic geographic isolation. By the late early Miocene Santacrucian Age, the orders Notoungulata, Litopterna, and Astrapotheria were ...
