Estudio de la biodiversidad de Ostrácodos actuales y su aplicación en la elaboración de funciones de transferencia para reconstrucciones paleoambientales del Holoceno en la provincia de Santa Cruz (50-52° S)Extant Ostracod biodiversity and its application in the development of transfer functions for Holocene paleoenvironmental reconstructions in Santa Cruz province (50-52° S)

Recording of climate and diagenesis through sedimentary DNA and fossil pigments at Laguna Potrok Aike, Argentina
(Copernicus Publications, 2016-04)
Aquatic sediments record past climatic conditions while providing a wide range of ecological niches for microorganisms. In theory, benthic microbial community composition should depend on environmental features and geochemical ...
Late Holocene hydrology inferred from lacustrine sediments of Laguna Cháltel (southeastern Argentina)
(Elsevier Science, 2014-07)
Hydrological changes that occurred during the last 4700 years have been reconstructed using multi-proxy analyses of sediment cores from the volcanic crater lake of Laguna Cháltel (50°S, 71°W). The chronology is based on ...
Paleolimnological response to climate variability during Late Glacial and Holocene times: A record from Lake Arturo, located in the Fuegian steppe, southern Argentina
(Elsevier Science, 2020-07)
Last Glacial Maximum and Holocene environmental conditions are reconstructed from a lacustrine core obtained from Lake Arturo, located in the Fuegian steppe of southern Argentina. Proxies include diatoms, ostracods, plants ...
Major lake level fluctuations and climate changes for the past 16,000 years as reflected by diatoms and chironomids preserved in the sediment of Laguna Potrok Aike, southern Patagonia
(Elsevier, 2013-07)
Laguna Potrok Aike is a maar lake located in southernmost Argentina and is one of the few permanent lakes preserving a continuous climatic record from the semiarid Patagonian steppe. Furthermore, its location close to ...
Two late pleistocene members of the white-grub complex, one of the most destructive insect pests of turfgrasses
(Sociedade Brasileira de Paleontologia, 2016-08)
We report the record of two members of one of the most destructive insect pests of turfgrasses from the Late Pleistocene of the Pampean region. The presence of Cyclocephala signaticollis and Diloboderus abderus 12,000 years ...
Oxygen isotope ratios of chironomids, aquatic macrophytes and ostracods for lake-water isotopic reconstructions - Results of a calibration study in Patagonia
(Elsevier Science, 2015-10)
Oxygen stable isotopes (δ18O) of biogenic sedimentary components from lake sediment archives, such as ostracod valves, are frequently used for palaeoclimatic reconstructions. However, the effects of host water isotope ...
On two species of Riocypris (Crustacea, ostracoda) from northern Patagonia and their relation to eucypris fontana: Implications in paleoenvironmental reconstructions
(National Research Council Canada-NRC Research Press, 2018-08)
Two species of ostracods new to Patagonia, Argentina, are described. One of them, Riocypris whatleyi sp. nov., is described for the first time, and the second, Riocypris sarsi (Daday, 1902) comb. nov., is reallocated from ...
