Differential use of trophic resources between an exotic and a coexisting native snail
(Springer Tokyo, 2021-08-11)
Knowing the interactions between exotic and native species is essential to establish possible threats to the local fauna. In this study, we assessed the use of food resources and diet overlap between a recently introduced ...
Key hydrological processes in the Del Azul Creek basin, sub-humid Pampean Plain
(Elsevier, 2021-02)
Groundwater plays an important role in the economic development of the Chaco-Pampean Plain (Argentina), where industry, agriculture and cattle farming are the main economic activities. The 66% of the country's population ...
From the Atlantic coast to the lowland forests: stable isotope analysis of the diet of forager‐horticulturists in southern Brazil
(John Wiley & Sons Ltd, 2021-11)
In this study, we analyze the diet of forager–horticulturalist societies of southeast South America through different isotopic markers (δ13Ccollagen, δ13Capatite, and δ15N). The economy of these populations was based on ...
Composition of Prehispanic Diets from Stable Isotope Analysis in Human Remains of the Southern Calchaquíes Valleys, Northwest Argentina (3600–1300 BP)
(Cambridge University Press, 2021)
This article discusses the composition of prehispanic diets based on the isotopic composition (δ13C, δ15N) of 10 human samples dated between 3600 and 1300 BP from the Cajón Valley in Northwest Argentina. The sample is the ...
Does trawl fisheries affect the diet of fishes? A stable isotope analysis approach
(Taylor & Francis Ltd, 2019-06)
Trawling is the main fishing practice worldwide and its ecosystem effects have been raising concern over the past decades. Long-term impacts can be monitored through changes in the trophic structure, and several studies ...
Isotopic niche partitioning between two small cetacean species
(Inter-Research, 2021-02)
Commerson’s dolphin Cephalorhynchus commersonii and Peale’s dolphin Lageno - rhynchus australis live in sympatry along the southwestern South Atlantic Ocean, suggesting the existence of some degree of habitat partitioning ...
Ontogenetic dietary changes in male South American fur seals Arctocephalus australis in Patagonia
(Inter-Research, 2015-04-09)
This study assessed ontogenetic dietary changes in male South American fur sealsArctocephalus australis in northern and central Patagonia (Argentina) using stable isotope ratios (δ15N and δ13C) in vibrissae and bones. ...
First snow, glacier and groundwater contribution quantification in the upper Mendoza River basin using stable water isotopes
(Taylor & Francis Ltd, 2020-08)
The Mendoza River streamflow, South America (∼32 °S), derives almost exclusively from winter snow precipitation falling in the Andes. Almost 70% of the water feeding the river originates in the Cordillera Principal geological ...
Composition of pre-Hispanic diets from stable isotope analysis in human remains of the Southern Calchaquíes Valleys, Northwest Argentina (3600-1300 BP)
(Cambridge University Press, 2021-03-15)
This article discusses the composition of prehispanic diets based on the isotopic composition (δ13C, δ15N) of 10 human samples dated between 3600 and 1300 BP from the Cajón Valley in Northwest Argentina. The sample is the ...
