investigate the osteological markers behavior in human
remains from a long-term perspective on the south coast of
Santa Catarina (Brazil), interesting results were obtained
from the Içara´s conchiferous site (Içara-01). The authors
analyzed osteological stress markers of Porotic Hyperostosis
(HP), Cribra orbitalia (CO) and Linear Enamel Hypoplasia
(LEH) in 35 individuals from Içara-01. They compared
the results with those obtained for individuals buried in
concomitant periods at Cabeçuda and Jabuticabeira II
shellmounds. The hypothesis is that the buried individuals
in Içara-01 could be members from a coastal group that used
the site as a cemetery and had mobility through the coast and
the highland, and not that came from the highland and used
Içara-01 as a temporary camp, as the literature postulates.

A visível concentração de sítios com características bastante semelhantes e ativos por centenas de anos tem levado a alguns pesquisadores a sugerir que os sambaquieiros conformariam um sistema social complexo e duradouro, apresentando uma estabilidade econômica, social e política ao longo de sua permanência no litoral. Esta continuidade de mais de 5 milênios sofreu transformações a partir de aproximadamente 2000 anos AP, quando surgem evidências de grupos humanos provavelmente provenientes de regiões interioranas, sendo elas o aparecimento de camadas predominantemente icitilógicas nos estratos mais recentes de alguns sambaquis e a presença de cerâmicas das tradições Itararé/Taquara. A proposta deste projeto foi testar a hipótese de que a continuidade e a estabilidade das ocupações sambaquieiras no litoral sul de Santa Catarina estão refletidas também na estabilidade do perfil do estresse durante todo o período de ocupação dos sítios, desde os sambaquis mais antigos até os sambaquis tardios. Para testar essa hipótese foram selecionadas séries esqueléticas oriundas de dois sambaquis com uma longa duração de ocupação, Cabeçuda e Jabuticabeira II, e o acampamento conchífero Içara. Estas séries foram analisadas segundo a ocorrência de marcadores de estresse fisiológico sistêmicos potencialmente capazes de informar sobre eventos estressores ocorridos durante a infância, entre eles, a anemia. Os dados apontam para mudanças nos padrões de ocorrência de estresse fisiológico nas séries esqueléticas de Cabeçuda e Jabuticabeira II, sinalizando certa variabilidade biocultural entre eles, tanto diacrônica quanto sincrônica, mesmo se em sua essência estrutural tais grupos são semelhantes. No caso de Içara, os dados sugerem que os indivíduos lá sepultados poderiam ter uma relação mais próxima com o litoral do que apenas a prática de acampamentos temporários por alguns meses do ano, conforme postula a literatura.

From the 1980s LEH analyses occurred concomitantly with studies of stable isotopes of δN and δC from bones and teeth.
In Brazilian archeology there are few skeletal series for which LEH and isotope studies have been combined in analysis, and for only one skeletal series from Santa Catarina coast shell middens at Jabuticabeira II (occupation between 3,137-1,524 years BP) is there δN and δC isotope analysis to investigate the weaning process (Pezo-Lanfraco et al, 2018). Considering 34 individuals analyzed in this series for LEH with isotopic assays for δN and δC, the results indicate that age at weaning did not differ much and occurred between 2 and 3 years of age (Pezo-Lanfranco et al, 2018) with peak frequency of LEH between 3 and 4 years of age (Giusto, 2017). On the other hand, Pezo-Lanfranco et al. (2018) in their study suggest greater individual variation in weaning practices.
From an osteobiographic perspective, this work presents an analysis of the stress profile of the individuals, as inferred from the occurrence of LEH, (in addition to porotic hyperostosis and cribra orbitalia, when possible), and isotopic signatures for individuals who were analyzed for these four elements in the Jabuticabeira II site.
