“…The Guiana genetic group is also one of the group with the fewest gene content and was found to be highly homozygous (Observed Heterozygosity of 7.9%) 21 . Archaeological research evidenced the presence of human populations settle in French Guiana dating from 4500 to 2000 BC 41 . The distribution of linguistic groups in contact in Amazonia 42 shows that the Tupi language family extended from Iquitos until to the mouth of the Amazon, and on either side including French Guiana, thus supporting possible contact between these two regions.…”

The Cacao tree (Theobroma cacao L.)is a major cash crop and an important source of income for millions of farmers across Africa, Asia and Latin America. However, cacao farmers and producing countries are facing multiple challenges including pest and disease management, sustainable production under threat of climate changes and diversification of cocoa flavor profiles. Addressing these challenging requires a deeper understanding of the existing genetic diversity of the species. Yet, very little is known about the intraspecific gene content variation.In this study, we used the genome of 216 accessions ofT. cacao(including 185 newly re-sequenced) covering a broad genetic diversity of the species to construct the first pan-genome of the cacao tree. As a result, we predicted a total of 30,489 pan-genes, enriching the reference Criollo genome with 1,407 new genes.Our analysis revealed that only a small fraction of these genes (9.2%) is dispensable, being absent in some individuals. However, these genes could represent a valuable resource for breeding efforts aimed at improving disease resistance in the species.We used this new pangenome resource to gain insights into how diversification and domestication processes have influenced genomic variability within the species. Notably, we observed a significant loss of genes within the domesticated Criollo genetic group. Furthermore, we found evidences suggesting that domestication processes have had an impact on the vigor and disease tolerance of Criollo accessions. In summary, our research has contributed to a better understanding of the cacao tree’s genome diversity. These findings offer new avenues for biological discovery and breeding, ultimately addressing the challenges faced by cacao farmers and producing countries.

“…Esse é o caso dos sítios arqueológicos Laranjal do Jari I e II, em que temos uma clara indicação de atos de construção da memória como expressão das interações que se estabelecem entre os vivos e os mortos. Essa hipótese ganha força ao lado de outros exemplos arqueológicos das Guianas, Caribe e foz do rio Amazonas (BEL, 2015;DUIN, 2009;GAMBIM JÚNIOR, 2016;HOOGLAND;HOFMAN, 2013;LIMA, 2017;SCHAAN, 2004;SALDANHA, 2017), bem como no Alto Madeira (COSTA; GOMES, 2016) que estão relacionados a diferentes contextos funerários e formações sociais.…”

Este artigo apresenta uma discussão acerca das atitudes dos vivos em relação aos mortos, com base na análise dos artefatos cerâmicos e seus arranjos espaciais, indicadores de rituais funerários relacionados aos sítios arqueológicos Laranjal do Jari I e II, antigas aldeias localizadas no sul do Amapá, que datam por volta dos séculos VIII a XV AD. As estruturas de deposição cerâmica revelaram a presença dos conjuntos cerâmicos Jari e Koriabo. A partir da análise tecno-funcional da cerâmica e associações com contextos de deposição e sepultamentos, sugerem-se formas de sociabilidade e concepções sobre vida e morte dessas sociedades pré-coloniais que diferem das noções de afastamento dos mortos e construção de novas identidades, comuns à maior parte das populações indígenas contemporâneas.

“…Cayo pottery in both sites is characterized by a variety of different vessel shapes (Boomert 1986; with modeled, incised, and painted motifs representing animals and creatures reflecting the worldview of the Kalinago peoples. Incised decorations recall stylistic motifs of the Greater Antilles, and bowls with carinated or indented rims (known as flower pots) and white painted inside surfaces with red or yellow designs are typical of the Koriabo style pottery from the South American mainland (Suriname, French Guiana, northern Brazil) ( Figure 2; Barreto et al 2020;Bel 2015;Boomert 1986;Rostain and Versteeg 2004;Versteeg 2003). Similarly, large bowls with modeled decorations representing animal/human faces served as containers for cassava (Manihot esculenta) beer and are typical for mainland complexes.…”

The Caribbean Sea was a conduit for human mobility and the exchange of goods and ideas during the whole of its pre-colonial history. The period cal. AD 1000-1800, covering the Late Ceramic Age and early colonial era, represents an archaeologically understudied time during which the Lesser Antilles came under increasing influence from the Greater Antilles and coastal South America and participated in the last phase of indigenous resistance to colonial powers. This article summarizes the results of the Island Network project, supported by the Netherlands Organisation for Scientific Research (NWO) in which a multidisciplinary set of archaeological, archaeometric, geochemical, GIS, and network science methods and techniques have been employed to disentangle this turbulent era in regional and global history. These diverse approaches reveal and then explore multi-layered networks of objects and people and uncover how Lesser Antillean communities were created and transformed through teaching, trade, migration, movement, and exchange of goods and knowledge.
