title: Ethnohistoric review of amylolytic fermentation in Amazonia

description: Abstract In South America’s lowlands, it was believed that fermentation processes for amylaceous substances were performed only with the inoculation of salivary amylase in the mash. In 2004, Henkel identified a unique fermentation process that was not previously known in the Americas: fermentation performed with the inoculation of an amylolytic mold, Rhizopus sp. Amylolytic fermentation is an important way to transform and enrich carbohydrates and is widely used in the eastern and southeastern Asia for the enhancement of beverages and food. To verify if this process was unique, extensive research has been carried out by analyzing reports by missionaries, travelers, and anthropologists to search for hints of a larger diffusion of such processes. This research made it possible to verify that the use of amylolytic molds was widespread throughout the Amazon basin, from Rio Napo and the upper Amazon to Guianas and Orinoco. In addition, it was possible to verify that Rhizopus sp. was not the only mold employed. It is probable that the other molds used were Monascus sp. and Aspergillus sp. This leads us to believe that the fermentation processes in the Amazon basin were likely more varied than previously thought, and are worthy of deeper studies.

title: The Recreio Shellmound: geoarchaeology, ictioarchaeology and etnoarchaeology

description: Abstract This article addresses the shellmound occupation process on the Itapeva barrier, identifying the sites and their builders within the chronology, along with their choices for implementation in a landscape affected by the dynamics of paleoenvironmental transformations. The Recreio shellmound’s position on a shallow coastal plain demonstrates a cultural choice based on an ancient way of life that was already developing on the southern and southeastern coast of Brazil almost two thousand years ago. While the excavations identified fish and fishing implements that were present during prehistorical times, they also indicated the need for associated traditional strategies and knowledge which can only be obtained through ethnography. The ichthyoarcheological data suggest an initial stage of occupation focused on species with more predictable availability such as mullet (Mugil sp.) and kingcroakers (Menticirrhus sp.). After the sites were definitively established, fishing strategies became more generalist; use of lakes and flooded areas is seen in the presence of species such as mullet (Mugil sp.), freshwater catfish (Rhamdia sp.), sea catfish (Genidens sp.), cichlids (Cichlidae), whitemouth croaker (Micropogonias furnieri), and hake (Cynoscion sp.). In general, each species seems to indicate different fishing strategies.

title: Early and Middle Holocene human ocuppations in Southwest Amazon

description: Abstract For many decades, there has bien a debate on whether earliest societies existed in the Amazon rainforest during the Early and Middle Holocene periods. At least for the past 20 years, increasingly strong evidence has placed the Amazon biome on the map of the first human occupations in the American continent. The present paper is part of this effort. It deals with the oldest human occupations evidenced in the upper Madeira River, Rondônia State, Brazil. Essentially, it analyzes the data produced in the publications of Eurico Miller combined with the investigations of the Upper Madeira Project team over the last ten years. Special emphasis is given to the latest interventions at the Teotonio archaeological site, where it was possible to identify and prove the existence of deep layers of human occupation dating from the Early and Middle Holocene.

title: Temporality of archaeological ceramics at the Teotônio site

description: Abstract In the portion of the Upper Madeira River which contains multiple waterfalls, the Teotônio archaeological site is especially notable: it is located on a plateau on the right side of the waterfall bearing the same name, and has been submerged by the construction of the Santo Antônio dam. The significance of this landscape, which includes an exceptional abundance of aquatic resources, seems to have contributed to the fact that all the known ceramic assemblages of the region are concentrated there, occurring over the more than three thousand years that the site was occupied. Technological analysis of this material permits inferences on the different ways these indigenous populations occupied Teotônio over time; treating this site as a microcosm of the long-term history of the Upper Madeira allows distinct temporalities in the use of this location to be identified.

title: Archaeology at the Santa Paula site, upper Madeira, Porto Velho, Rondônia, Brazil

description: Abstract This paper presents the preliminary results of archaeological research by the Federal University of Rondônia at the Santa Paula site, which is located on a terrace on the left bank of the Teotônio waterfall on the upper Madeira River, in Porto Velho, Rondônia. This fieldwork was conducted from 2014 to 2016 and contributes to regional archaeology as a form of indigenous cultural history. These activities included historical and cultural contextualization, topography, excavation, dating, curation, and analysis of ceramic objects. The findings indicate that the site was occupied for over three thousand years, initially by people who utilized Santa Paula ceramics and the Pocó-Açutuba, Morro dos Macacos, Barrancoid, and Polychrome technical traditions, as well as historically recognized indigenous peoples, the Portuguese, and river dwellers. But the most striking transformations to this site, such as the construction of mounds around a central plaza and production of Amazon dark earth soils, began 1,600 years ago by the Barrancoids, who like the Pocó-Açutuba tradition can be associated with the expansion and cultural influence of the Arawak throughout the Amazon and beyond.

title: Circular village and objects associated with indigenous occupation on the left bank of the Santo Antônio Waterfall

description: Abstract This article discusses indigenous occupation of a circular village in the fifteenth century in terms of its shape and analysis of pottery found at the Novo Engenho Velho archaeological site on the upper Madeira river. These spatial components are analyzed against known archaeological settlement patterns. Technical and functional analysis of the ceramics indicates standardized vessel production, with variations according to different functions and activities. These elements are been considered to be associated with Jatuarana ceramics (polychrome tradition); the presence of these objects in a circular village has implications for the current archaeological models proposed for the Amazon.

title: Ceramic technologies on the upper Madeira River: summary, timeline, and perspectives

description: Abstract The characteristic choices of clay types, production techniques, shaping, finishes, firing, and use marks in the chains of production and use for ceramic artefacts indicate the presence of at least five distinct technological groups in the upper Madeira River region from about 3,000 BP to the eighteenth century. This article summarizes the technological variations in order to reflect on classifications, recognition of local and regional traditions, continuities and changes in the archaeological groups and contexts. This information make it possible to describe cultural transformations as well as persistence among the people who produced these ceramics during the long span of occupation in this region.

title: The archaeology of the Upper Madeira within the archaeological context of Amazonia

description: Abstract This article reviews the data currently available on the area downstream of the waterfalls on the Upper Madeira River. This is a key segment of the largest tributary of the Amazon River, with headwaters in the Central Andres: it is comprised of the union of the Mamoré, Beni, and Madre de Dios, three great rivers flowing from Bolivia and Peru. Comparative analysis suggests that the archaeology in the area downstream of the waterfalls of the Madeira River bears more resemblance to patterns observed in central Amazonia than in the region upstream. On the other hand, the Upper Madeira also features elements related to the surrounding cultural diversity. We consequently suggest that the waterfalls acted as an enduring boundary throughout the Late Holocene, connecting regions with distinct cultural patterns within Amazonia.

title: From vast public lands to the narrowness of sold land: reflections on quilombola territories and communities in northern Mato Grosso do Sul

description: Abstract In this article the authors analyze transformations in the forms of land access among different segments of society in the north of the Brazilian state of Mato Grosso do Sul. The discussion focuses on the Família Bispo quilombola community in the municipality of Sonora, a region historically linked to a border area between the Bororo and Kayapó indigenous peoples. The case analyzed is emblematic because it includes indigenous people, quilombolas, and migrants from other Brazilian states, all involved in alliances and disputes mainly surrounding land tenure and ownership. The transformation of space with the consent and participation of government agents, resulted (as one interlocutor stated) in the expropriation of indigenous and quilombola territories, because the vast public lands were transformed into land that was sold and privately owned, regularized through contracts and notary deeds.

title: Agency and contingency in land access and peasant social reproduction in the Mearim River Valley, Maranhão

description: Abstract In this article, we examine the family trajectories of three rural leaders in the Mearim Valley, which illustrate the main forms of land access by Maranhão’s peasantry over the past 150 years. An analysis of these trajectories, captured as allegories, shows how the contingencies experienced by this peasantry, despite unfavorable interactions in the social structure and under the legal apparatus of the Brazilian State, manage different levels of agency to ensure their social reproduction while remaining on the land. In the three cases studied, the collective action processes and political articulation performed by the interviewees in response to these contingencies represent discontinuities between generations, with different consequences for family trajectories. In only one case, the practices and discourses that expanded the family group's agrarian base were maintained, in contrast to apparent stagnation and contraction observed in the other cases. The analysis indicates that the range of possibilities for contemporary rural peasants takes into account relevant interactions of the family unit with the formal land market, as well as socio-political relations established beyond kinship.

title: Archaeobotanical records in an Amazonian shell mound: microalgae (Diatomacea,Bacillariophyta) as indicators of environmental changes

description: Abstract Records of the conditions during the formation of archaeological sites were obtained from interdisciplinary investigations. In archaeobotany, diatoms are microalgae that can depict these previous conditions; when present in archaeological soils, they indicate the presence of watercourses near the site or may permit inferences about paleoenvironmental conditions. This study is the first to describe the diatom record throughout the entire anthracological column of a shell mound. Samples from the Porto da Mina Shell Mound (Quatipuru, Pará, Brazil) were analyzed along the sedimentary column. The diatoms found in the mound reinforce the notion that groups have been associated with the shell mound at the site for at least 210 years. The ecological inferences indicate that the settlement was in a geographically diverse environment, with fresh, brackish, and marine water entering. The inclusion of diatom analysis in the archaeological context represents an additional technique for environmental reconstruction studies.

title: Sinister places in Venezuelan rock art, or the logical contradictions of peasant logic/cultural heritage

description: Abstract From data collected through documentary and field research techniques, and using conceptual units of analysis supposedly framed within animistic theories, here we present some premises that attempt to explain intrigues significant to the community on rock art in Venezuelan historical regions, as well as their relationship with the notion of cultural heritage. The possibility that certain local representations contradict the concept of heritage is also suggested. Nevertheless, these referents provide meaning for rock art within the conceptualized landscape in which it is inserted and are consequently an element to consider in the process of patrimonialization by, for, with, and within the communities.
