Isotopic ecology and human diets in the forest–sseppe ecotone, Aisén Region, Central-Western Patagonia, Chile
(Wiley, 2014)
This work aims to build a comprehensive isotopic ecology with the ultimate purpose of assessing long-term
human diet decision-making by means of stable isotope analysis. We present a set of δ13Ccollagen and
δ15Ncollagen ...

Testing the niche variation hypothesis in a community of passerine birds
(Ecological Society of America, 2017)
The niche variation hypothesis (NVH) predicts that populations with broader niches should exhibit greater between- individual diet variation or individual specialization (IS) relative to populations with narrower niches. ...
Using delta C-13 stable isotopes to quantify individual-level diet variation

Human-modified landscapes narrow the isotopic niche of neotropical birds
(Springer, 2021-04-09)
Deforestation and habitat loss resulting from land use changes are some of the utmost anthropogenic impacts that threaten tropical birds in human-modified landscapes (HMLs). The degree of these impacts on birds' diet, ...
The ecological causes of individual specialisation
(Wiley-Blackwell, 2011-09-01)
Many generalist populations are composed of specialised individuals, whose niches are small subsets of the population niche. This 'individual specialisation' is a widespread phenomenon in natural populations, but until ...

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 ...
