PEREZ, Suray A.. La explotación de moluscos intermareales durante el Holoceno tardío en la localidad de Heshkaia, bahía Moat, sur de Tierra del Fuego. Intersecciones antropol. [online]. 2020, vol.21, n.1, pp.43-55. ISSN 1850-373X.

INTERTIDAL MOLLUSC EXPLOITATION DURING THE LATE HOLOCENE AT THE HESHKAIA LOCALITY, BAHÍA MOAT, SOUTHERN TIERRA DEL FUEGO. This paper examines the archaeomalacological record of the Heshkaia locality, situated at the eastern mouth of Beagle Channel. Taxonomic identification and biometric analysis of shells from three Late-Holocene assemblages are performed to assess the incidence of anthropic and natural forces in the observed trends. Results support a shellfish gathering strategy centered on suboptimal blue mussels (Mytilus edulis) stripping along the occupational sequence in the locality. It is inferred that the importance of mollusks in human subsistence derived from their abundance and accessibility, rather than their nutritional contribution. In addition, temporal changes in mean shell size of some species cannot be explained by sea surface temperature variations and instead a constant human harvest pressure scenario is suggested. Although this limited the maximum length mollusks could grow, it did not affect their long-term local reproduction. These results contribute new information on mollusk exploitation patterns and allow examination of continuities and differences with previous studies in the south coast of Tierra del Fuego.
