Bromus tectorum invasion in South America: Patagonia under threat?
(Wiley Blackwell Publishing, Inc, 2014-02)
Bromus tectorum (cheatgrass) is an aggressive invasive species posing threats to native ecosystems including increase in fire frequency, alteration of water and nutrient cycles and exclusion of native species. As such, it ...
Environment, space, and morphological variation of projectile points in Patagonia (Southern South America)
(Pergamon-Elsevier Science Ltd, 2016-11)
The aim of this work is to assess shape variation in Patagonian stemmed projectile points related to spatial and environmental factors by means of geometric morphometric and multivariate methods. The sample includes 1445 ...
Paleomagnetism and magnetic fabric of Middle Jurassic dykes from Western Patagonia, Argentina
(Elsevier Science, 2000-06)
Jurassic volcanism in Patagonia is widespread. Although associated dyke swarms are conspicuous, they have been almost neglected in previous geologic studies of this region. Radiometric, paleomagnetic and magnetic anisotropy ...
Summer heat waves in southeastern Patagonia: an analysis of the intraseasonal timescale
(Wiley, 2016-03)
We explore the occurrence of intraseasonal summer heat waves in southeastern Patagonia (SEPG, 46∘ –52∘S; 65∘ –70∘W) since the late 19th century by means of the Twentieth Century Reanalysis version 2 (20CRv2). In total, we ...
New hadrosaurid (Dinosauria: Ornithopoda) fossils from the uppermost Cretaceous of central Patagonia and the influence of paleoenvironment on South American hadrosaur distribution
(Pergamon-Elsevier Science Ltd, 2021-10)
We describe and incorporate fragmentary new cranial and postcranial materials of hadrosaurid ornithopods into the non-avian dinosaur assemblage of the Upper Cretaceous (Coniacian–Maastrichtian) Lago Colhué Huapi Formation ...
Hunter-gatherer plant resource use during the Holocene in central western Patagonia (Aisén, Chile, South America)
(Springer, 2017)
Recent archaeobotanical studies on hunter-gatherer sites in the steppes of central western Patagonia, Chile, reveal new data on the use of plant resources throughout the Holocene, often previously assumed to be unimportant. ...
Endangered species, archaeology, and stable isotopes: Huemul (Hippocamelus bisulcus) isotopic ecology in central-western Patagonia (South America)
(Academic Press, 2011)
The management and conservation of animal species should be based upon a long-term analysis that considers its geographical distribution and feeding patterns. The study of carbon and nitrogen stable isotopes on skeletal ...
Notes on rare clavarioid species (Fungi: Basidiomycota) in Patagonia, Argentina
(Biotaxa, 2015-03)
The distributions of two clavarioid species, Clavulinopsis laeticolor (Berk. and M.A. Curtis) R.H. Petersen (Agaricales, Clavariaceae) and Lentaria rionegrensis R.H. Petersen (Gomphales, Lentariaceae), are extended and ...
