Biocultural heritage preservation relies on ethnobotanical knowledge and the paleoethnobotanical data used in (re)constructing histories of human–biota interactions. Biocultural heritage, defined as the knowledge and practices of Indigenous and local peoples and their biological relatives, is often guarded information, meant for specific audiences and withheld from other social circles. As such, these forms of heritage and knowledge must also be included in the ongoing data sovereignty discussions and movement. In this paper we share the process and design decisions behind creating an online database for ethnobotanical knowledge and associated paleoethnobotanical data, using a content management system designed to foreground Indigenous and local perspectives. Our main purpose is to suggest that the Mukurtu content management system, originally designed for physical items of cultural importance, be considered as a potential tool for digitizing and ethically circulating biocultural heritage, including paleoethnobotanical resources. With this database, we aim to create access to biocultural heritage and paleoethnobotanical considerations for a variety of audiences while also respecting the protected and sensitive natures of Indigenous and local knowledges.
A particular type of miniature ceramic vessel locally known as “veneneras” is occasionally found during archaeological excavations in the Maya Area. To date, only one study of a collection of such containers successfully identified organic residues through coupled chromatography–mass spectrometry methods. That study identified traces of nicotine likely associated with tobacco. Here we present a more complete picture by analyzing a suite of possible complementary ingredients in tobacco mixtures across a collection of 14 miniature vessels. The collection includes four different vessel forms and allows for the comparison of specimens which had previously formed part of museum exhibitions with recently excavated, untreated containers. Archaeological samples were compared with fresh as well as cured reference materials from two different species of tobacco (Nicotiana tabacum and N. rustica). In addition, we sampled six more plants which are linked to mind-altering practices through Mesoamerican ethnohistoric or ethnographic records. Analyses were conducted using UPLC-MS metabolomics-based analytical techniques, which significantly expand the possible detection of chemical compounds compared to previous biomarker-focused studies. Results include the detection of more than 9000 residual chemical features. We trace, for the first time, the presence of Mexican marigold (Tagetes lucida) in presumptive polydrug mixtures.
In the Mexican state of Yucatán, the Industrial Revolution is intimately linked to the cultivation and commercialization of henequen (Agave fourcroydes). The second half of the nineteenth and the first decade of the twentieth century are most often referred to as the region’s Gilded Age. Some local families accrued immense wealth, while many peasants were essentially enslaved. The city of Mérida saw the construction of magnificent mansions, and the new port of Progreso was connected through thousands of kilometers of railroads. At the same time, the rural landscape experienced the foundation of countless new and the expansion of existing haciendas. In this article, we provide a comparison of the relational memory of local communities regarding three of these historical settlements: San Pedro Cholul, San Antonio Nohuayún, and San Antonio Sihó. We present the circumstances leading to the historical archaeology project at San Pedro and recount our efforts at involving its descendant community. In the face of the recent destruction of San Pedro’s core buildings, we end with a discussion about the potential fates of Yucatan’s henequen haciendas and a series of suggestions on how to safeguard related material remains, while allowing stakeholders to benefit from historic preservation.
This paper focuses on the recovery of archaeological starch grains from building interiors at pre-Columbian Maya sites in southern Mexico. In an effort to render analytical protocols more effective, it examines the performance of chemical residue tests as prospective tools, proposes a customized extraction procedure for lime-plaster floors, and compares the efficacy of two mounting techniques. While the alleged predictive power of proxies like phosphate and carbohydrate tests could not be confirmed, the customized plaster processing protocol not only simplifies the extraction process but also results in the recovery of dense assemblages of individual starches as well as grain clusters. However, despite increases in protocol efficacy, architectural context and building history continue to be factors of utmost importance for microbotanical analyses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
