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, ...
Intraspecific variability in isotopic composition of a monomorphic seabird, the Common Tern ( Sterna hirundo ), at wintering grounds
(Csiro Publishing, 2019-04)
Understanding sex differences in foraging behaviour has important implications for breeding biology and population ecology. This requires the evaluation of segregation throughout the annual cycle, including the non-breeding ...
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 ...
Controls over spatial and seasonal variations on isotopic composition of the precipitation along the central and eastern portion of Brazil
(2017-09-03)
Based on Global Network Isotopes in Precipitation (GNIP) isotopic data set, a review of the spatial and temporal variability of δ18O and δ2H in precipitation was conducted throughout central and eastern Brazil, indicating ...
Variations in human body water isotope composition across the United States
(Elsevier, 2021-10)
Accurate human provenancing using stable isotopes depends directly on solid understandings of the geographic and individual factors affecting isotope variability and incorporation into human tissues. Transfer of isotopic, ...
Stable isotopes of carbon and nitrogen in the study of organochlorine contaminants in albatrosses and petrels
(2014-04-22)
Carbon and nitrogen stable isotopes in albatrosses and petrels collected off southern Brazil were compared with concentrations of organochlorine contaminants (OCs). d13C and d15N values, as well as OCs concentrations, ...
Stable isotopes (δ2H e δ18O) assessment methods in hydrology: a reviewMétodos de avaliação de isótopos estáveis (δ2H e δ18O) na Hidrologia: uma revisão
