Isotopic insight on paleodiet of extinct Pleistocene megafaunal Xenarthrans from Argentina
(Elsevier Science, 2017-08)
The diet of extinct giant Xenarthrans is a debated topic, especially for ground sloths, for which herbivory, insectivory, and carnivory through scavenging or active hunting have been suggested. In this study, stable carbon ...
Global perturbation of the marine Ca isotopic composition in the aftermath of the Marinoan global glaciation
(ELSEVIER SCIENCE BV, 2010)
Ca isotopic compositions of Marinoan post-glacial carbonate successions in Brazil and NW Canada were measured Both basal dolostones display delta(44/40)Ca values between 1 and 0 7 parts per thousand overlying limestones ...
Inter- and intraspecific variation in the use of marine food resources by three Cinclodes (Furnariidae, Aves) species: Carbon isotopes and osmoregulatory physiology
(Elsevier GmbH, 2002)
The avian genus Cinclodes (Furnariidae) includes species that inhabit both inland and marine shores. We compared the carbon isotopic
composition and osmoregulatory capacities of field caught individuals of three Cinclodes ...
Stable isotope compositions of South American camelids in the Dry Puna of Argentina: A frame of reference for the study of prehistoric herding and hunting strategies
(Elsevier, 2018-04)
The prehistoric pastoralist groups that inhabited the Dry Puna of Argentina employed a combination of subsistence strategies that included the herding of domestic South American camelids and the hunting of wild ones since ...
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 ...
Abundância natural do isótopo estável de carbono (13C) de alguns itens alimentares e sua contribuição no crescimento de juvenis de pintado, Pseudoplatystoma corruscans (Agassiz, 1829) (Osteichthyes, Pimelodidae)
(2002-12-01)
The aim of this study is to determine the natural abundance of carbon stable isotope (13C) of some food components and determine its contribution to the pintado juvenile growth, in laboratory conditions. 150 fishes were ...
