Resumen:
In this chapter, we provide along-term perspective on the interaction between hunter-gatherer-fishersocieties and marine resources in the southern tip of South America through theapplication of stable isotope ecology. Given the complexities of discussionsand methodological paths, we present the information in three different cases.The emphasis is both on their complementary nature to archaeofaunal studies, aswell as an independent line of inquiry about patterns of human subsistence overtime. We begin by describing the modern and past environment of Tierra delFuego and the ecological niche of fauna, in order to formulate spatial patternsof stable isotopes distributions through the food web (Newsome et al. 2007).This model is based on the general spatial gradient of δ13C values ininshore-offshore habitats (France 1995; Koch 2007). In the first archaeologicalcase, we evaluate if Otariid populations changed their foraging behavior inresponse to human predation through the Holocene (Nye 2019; Zangrando et al.2014). The second case compares the isotopic values of different fish taxa toassess the use of offshore patch during the late Holocene and the increasedlabor investment in human fishing activities (Zangrando et al. 2016). Finally,we present a local isotopic ecology for both marine and terrestrialenvironments as a paleoecological frame of reference (Kochi et al. 2018). Ourultimate objective is to understand the causal factors that led to adiversified diet of prehistoric human remains that date to the late Holocene.The whole picture demonstrates a more complex scenario of the marine food web,particularly with respect to the trophic relations between taxonomical groups,and it also highlights the limitations in paleodietary reconstructions.
