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 ...
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 ...
The isotopic composition and insect content of diet predict tissue isotopic values in a South American passerine assemblage
(Springer, 2013)
We analyzed the carbon and nitrogen isotopic
values of the muscle, liver, and crop contents (‘‘diet’’) of
132 individuals of 16 species of Chilean birds. The nitrogen
content of diet was tightly correlated with the ...
Snow Stable Isotope Composition Variability Related to the Upper Mendoza River Basin Hypsometry
(Academicians' Research Center, 2017-12)
The water supply of the northern oasis of the Mendoza province, in the central western of Argentina, depends mainly on the melting of precipitated and accumulated snow during the winter, which supplies water for domestic, ...
Body mass predicts isotope enrichment in herbivorous mammals
(Royal Society Publishing, 2018)
Carbon isotopic signatures recorded in vertebrate tissues derive from ingested food and thus reflect ecologies and ecosystems. For almost two decades, most carbon isotope-based ecological interpretations of extant and ...
Impact of elevation and weather patterns on the isotopic composition of precipitation in a tropical montane rainforest
(2013)
This study presents the spatial and temporal variability of δ18O and δ2H isotope signatures in precipitation of a south Ecuadorian montane cloud forest catchment (San Francisco catchment). From 2 September to 25 December ...
Infrared study and isotopic effect of magnesium hydroxide
(Elsevier Science BvAmsterdamHolanda, 2001)
Paired isotope records of carbonate and organic matter from the Middle Ordovician of Argentina: Intrabasinal variation and effects of the marine chemocline
(Elsevier Science, 2017-10)
We investigate the expression of the Middle Darriwilian isotope carbon excursion (MDICE) across marine shelf environments in the Argentine Precordillera. Previous work identified the MDICE in the Las Chacritas Formation ...
