Bio-archaeological evidence of olive tree (Olea europaea L.) irrigation during the Middle Ages in Southern France and North Eastern Spain

Quantitative eco-anatomical analyses were carried out on charred wood from modern olive trees (Olea europaea L.) in order to quantify influence of irrigation on wood characters and to detect irrigated olive specimens among charcoal assemblages dating back to the Middle Ages.     

Inclusion in Public Archeology in Brazil: Remarks on Collaborative Practices

There are several experiences of Public Archaeology in Brazil. In this paper, we will focus our attention on an experience developed by the Public Archeology Laboratory Paulo Duarte (LPA), located in the Center of Environmental Studies and Research (Nepam), University of Campinas, Brazil. Four main concepts have been used in this work: collaboration, inclusion, conflict, and subjectivity. We will develop the experiences between archaeologies and communities, and how these relations are linked with archaeological practice and interpretation.     

Ancestral Puebloan mtDNA in context of the greater southwest

Ancient DNA (aDNA) was extracted from the human remains of seventy-three individuals from the Tommy and Mine Canyon sites (dated to PI-II and PIII, respectively), located on the B-Square Ranch in the Middle San Juan region of New Mexico. The mitochondrial DNA (mtDNA) haplogroups of 48 (65.7%) of these samples were identified, and their frequency distributions were compared with those of other prehistoric and modern populations from the Greater Southwest and Mexico. The haplogroup frequency distributions for the two sites were statistically significantly different from each other, with the Mine Canyon site exhibiting an unusually high frequency of haplogroup A for a Southwestern population, indicating the possible influence of migration or other evolutionary forces. However, both sites exhibited a relatively high frequency of haplogroup B, typical of Southwestern populations, suggesting continuity in the Southwest, as has been hypothesized by others (8, 9, 29, 45 and 57). The first hypervariable region of twenty-three individuals (31.5%) was also sequenced to confirm haplogroup assignments and compared with other sequences from the region. This comparison further strengthens the argument for population continuity in the Southwest without a detectable influence from Mesoamerica.
