Influencia Da Evolução Costeira Holocênica Na Ocupação Por Grupos Sa., Mbaquieros: Resultados Das Prospecções Arqueológicas Nas Regiões Litorâneas Dos Estados De Sergipe E Da Bahia No Nordeste Do Brasil

Abstract

The greatest evidence of the pre-colonial presence that occupied the coastal region are archaeological sites called coastal sambaquis. Aiming to identify potential areas for installation of sambaqui groups on the coast of Sergipe and Bahia, it was proposed to use an unusual approach in Brazilian archeology which is to use, as a starting point, an understanding of the evolution of the coastal zone in the last 5600 cal years BP, to guide the archaeological exploration in search of shell mounds sites. The prospecting work carried out resulted in the discovery of archaeological sites of the sambaqui type on the northern coast of Bahia. This study becomes relevant when enabling increase of information concerning its physical environment and the transformations experienced by the coastal zone during the Holocene and their impact on pre-colonial occupation of the region.

Testing the resource economic monopolization hypothesis and its consequences for the mating system ofAlpheus estuariensis(Decapoda, Caridea, Alpheidae)

“…The shrimps were collected in two muddy flat areas named A1 (11°05′47″S 37°09′30″W) and A2 (11°07′32.08″S 37°09′22″W), both located in one of the mean estuarine systems of Sergipe State, Brazil, the estuary of the Vaza-Barris River, during August to November 2016. The region is characterized by a quasi-uniform seasonal thermal regime, in which rainfall constitutes one of the main elements of climate (Amâncio-Martinelli et al ., 2013). In this mixohaline ecosystem, mangroves occur in a low tide plain environment occupying an area of 59.37 km 2 (Carvalho & Fontes, 2007).…”

Ornament, Weapon, or Tool? Microwear Analysis of Shark Teeth from the Rio Do Meio Site in Florianópolis, Brazil

“…Shell mounds are common all along the Brazilian coast, increasing in size and frequency toward the south. Formerly defined as part of the same sociocultural system, shell mounds or sambaquis in fact show variations between sites and regions, and their analysis reveals more complex dynamics (Amâncio-Martinelli et al 2013; Guimarães et al 2005; Lessa 2011; Lessa and Carvalho 2015; Lessa and Coelho 2010; Lessa and Gaspar 2014; Lima 2000; Scheel-Ybert et al 2003; Scherer et al 2015). Although shell mounds are the best known and most studied coastal structures in Brazil, they are not the only features to be considered.…”
