The Laguna Potrok Aike Scientific Drilling Project PASADO (ICDP Expedition 5022) [PDF]

open access: yesScientific Drilling, 2009
In the Southern Hemisphere long, continuous, and high-resolution series of terrestrial paleoclimatic data are scarce, and they are only slowly emerging. Globally speaking, the most extreme oceanic character is encountered between 40°S and 60°S (Fig.

A uniform isotopic and chemical signature of dust exported from Patagonia: Rock sources and occurrence in southern environments [PDF]

open access: yes, 2007
Patagonia is considered to be the most important source of dust from South America that is deposited in surrounding areas, and we present here a systematic Sr and Nd isotopic study of sediment currently being exported.

The signature of river- and wind-borne materials exported from Patagonia to the southern latitudes: a view from REEs and implications for paleoclimatic interpretations [PDF]

open access: yes, 2004
Riverine and wind-borne materials transferred from Patagonia to the SW Atlantic exhibit a homogeneous rare earth element (REE) signature. They match well with the REE composition of Recent tephra from the Hudson volcano,and hence this implies a ...

Velocities of Major Outlet Glaciers of the Patagonia Icefield Observed by TerraSAR-X [PDF]

open access: yes, 2008
The capabilities of TerraSAR-X data for feature tracking by amplitude correlation over glacier surfaces are investigated. Methodical aspects of the amplitude correlation approach are described.

Ploidy levels and reproductive behaviour in invasive Hieracium pilosella in Patagonia [PDF]

open access: yes, 2011
Within a population of invasive Hieracium pilosella in Chilean Patagonia we found two ploidy levels, pentaploid and hexaploid. Each ploidy level was represented by one clone.

Fouling community dominated by Metridium senile (Cnidaria: Anthozoa: Actiniaria) in Bahía San Julián (southern Patagonia, Argentina)

open access: yesScientia Marina, 2015
The objective of this study is to provide information about a harbour-fouling community dominated by Metridium senile in southern Patagonia. Several steel tubes from the wharf of Puerto San Julián were extracted to perform repair tasks, allowing the ...

Health at the time of Native-European contact in Southern Patagonia: First steps, results, and prospects

open access: yesMemorias do Instituto Oswaldo Cruz, 2006
The objective of this paper is to present the first steps into the study of health in southern Patagonia during pre and post Native-European contact. Thus, our work has a double purpose.

Maintenance of genetic diversity in an introduced island population of guanacos after seven decades and two severe demographic bottlenecks: implications for camelid conservation. [PDF]

open access: yesPLoS ONE, 2014
Fifteen guanacos were introduced to Staats Island in the Falklands/Malvinas archipelago from Patagonia in the 1930s. Twenty five years later, the population was culled from 300 to 10-20 individuals, but quickly rebounded to a population of almost 400 ...

Genetic Structure and Gene Flow of Moss Sanionia uncinata (Hedw.) Loeske in Maritime Antarctica and Southern-Patagonia

open access: yesFrontiers in Ecology and Evolution, 2018
Bryophytes are a major component of vegetation in ice-free coastal regions of Antarctica. Sanionia uncinata (Hedw.) Loeske is distributed from northern and central Maritime Antarctica to Marguerite Bay in the southern part of this biome where it occurs ...
