The paleoclimatic context for South American Triassic vertebrate evolution
(Pergamon-Elsevier Science Ltd, 2021-10)
The Triassic Period was the setting for the origin and early diversification of Mesozoic ecosystems after the end-Permian mass extinction. The study of the Triassic is essential to understand the evolution of non-marine ...

Genomic evidence of demographic fluctuations and lack of genetic structure across flyways in a long distance migrant, the European turtle dove
(BioMed Central, 2016-11)
Background: Understanding how past climatic oscillations have affected organismic evolution will help predict the impact that current climate change has on living organisms. The European turtle dove, Streptopelia turtur, ...
A paleoclimatic review of southern South America during the late Paleozoic: a record from icehouse to extreme greenhouse conditions
(Elsevier, 2013-01-23)
This paper proposes a review of the Late Mississippian to Permian paleoclimatic history for southern South America based on lithologic indicators, biostratigraphic information, and chronostratigraphic data. The region is ...
Late Quaternary palaeosol records from subtropical (38°S) to tropical (16°S) South America and palaeoclimatic implications
(Pergamon-Elsevier Science Ltd, 2009-03)
Loess and palaeosols in the subtropical lowlands of South America (∼23-38°S) have a large potential to serve as archives of Late Quaternary environmental and climate changes. At present, mean annual precipitation generally ...

PALEOCLIMATIC CONTROLS ON STABLE OXYGEN AND CARBON ISOTOPES IN CALICHE OF THE ABO FORMATION (PERMIAN), SOUTH-CENTRAL NEW-MEXICO, USA
(Sepm-soc Sedimentary Geology, 1991-07-01)
The stable oxygen and carbon isotopic composition of caliche in fluvial and supratidal rocks of the Abo Formation (Permian), south-central New Mexico, is controlled by palecoclimate and depositional environment. Fluvial ...
