Archaeologists have long compared the Hohokam world of the North American Southwest to contemporary traditions in Mesoamerica and West Mexico. A degree of cultural connectivity between the Southwest and Mesoamerica is evident in similarities in public architecture, ceramic technology and design, ritual paraphernalia, and subsistence, among other qualities. Researchers commonly frame this connectivity in economic or cultural evolutionary terms that position Hohokam communities as somehow descendant from or dependent on more complexly and hierarchically organized societies far to the south. In this paper, I examine this connectivity through the lens of iconography to show that shared religious themes and archetypes were strands within the nexus. I focus on three iconographic subjects in Hohokam media—serpents, flowers, and "pipettes"—each of which materializes seemingly Mesoamerican religious concepts. From a careful consideration of the inception and breadth of each, I argue that Hohokam artisans began to portray these subjects in concert with a religious revitalization movement that drew a degree of inspiration from the south. However, while the iconography may have been new to Hohokam media, the religious themes were not. I show that the iconography references Archaic religious archetypes and cosmological principles that probably accompanied the spread of agriculture millennia before the formation of the Hohokam world. Rather than representing a new religion, I suggest Hohokam artisans materialized these long-established and unquestioned principles in novel iconographic ways as a means of naturalizing and ordaining the rapid social change that accompanied the religious revitalization movement.

Cerros de trincheras in northern Sonora and southern Arizona have traditionally been interpreted as short-term, defensive refuges. This paper reviews recent evidence concerning the functions of such sites by focusing on survey mapping, and excavation results gained over the past 12 years at several Tucson Basin cerros de trincheras. This evidence suggests that the Tucson Basin sites, and probably other cerros de trincheras as well, were not used as emergency defensive retreats. They instead were used for a variety of activities during the Hohokam early Classic period. The largest and most complex sites apparently were habitation villages, supporting hillside and hill summit pit houses and masonry rooms, large and small stone terraces, and massive, walled compounds. Artifacts and other evidence indicate that some of the terraces apparently were used for cultivation, and that the compounds may have accommodated ceremonies. Symbolic aspects of cerros de trincheras, particularly the highly visible terraces and compounds, are discussed. It is proposed that cerros de trincheras of southern Arizona were an important part of widespread organizational and ideological changes that took place during the early Classic period.

Background and Scope Agaves played a central role as multi-use plants providing food, fibre and beverage to pre-contact and historical Mesoamerican cultures. However, their importance to Indigenous Peoples in the Southwest USA and northern Mexico, where they occur because of adaptations such as CAM photosynthesis, is less well known. Archaeological research indicates the Hohokam and other pre-contact Southwestern agrarian people increased agricultural potential in this region by engineering riverine terraces and bajadas for agave dry farming. Agricultural features such as terraces and rock piles were especially characteristic of post-1000 CE with the increase of dense, aggregated populations. We present an overview of six pre-contact agave domesticates (PCADs) the Hohokam and other cultures cultivated, and their ecological and cultural attributes. These PCADs are Agave murpheyi , A. delamateri , A. phillipsiana , A. sanpedroensis , A. verdensis and A. yavapaiensis. Conclusion Pre-contact agriculturists cultivated at least six once cryptic domesticated agave species in the modern Arizona landscape associated with pre-contact agricultural features, such as rock structures. Because of the longevity and primarily asexual reproduction of these agaves, relict clones have persisted to the present day, providing an opportunity to study pre-contact nutrition, trade, migration and agricultural practices. Taxonomic data imply that pre-contact farmers selected desirable attributes, initiating domestication processes that resulted in discrete lineages. These agaves are morphologically and genetically distinct from Southwest US and northern Mexico wild agaves and Mesoamerican wild and domesticated species. Additionally, the remnant clones present a rare opportunity to examine domesticates virtually unchanged since they were last cultivated prehistorically. These discoveries underline the need to view landscapes and some plant species from a cultural, rather than 'natural', perspective and discern potential cryptic species veiled by traditional taxonomic treatments. Protecting and understanding the distribution, and ecological and cultural roles of these plants require interdisciplinary collaboration between botanists, archaeologists, federal agencies and Indigenous Peoples.

Recent observations and archival research on the archaeology of the Puerto Peñasco area at the northern end of the Gulf of California, Sonora, Mexico, have provided additional insights into the prehistory of the region. The northern Gulf of California has long been recognized as the source of raw marine shell used in the production of shell ornaments by the Hohokam of southern and central Arizona. The most obvious archaeological manifestations in the area are the shell midden sites that occur along the margins of the ocean and estuaries of the region. Based on a small sample of diagnostic flaked stone and ceramic artifacts, a Late Archaic period through Late Ceramic period (Hohokam) use of the area is evident. A small number of independently derived radiocarbon dates appear to support this conclusion. We summarize archaeological, chronometric, environmental, and geomorphic data from the area.

Five recent radiocarbon assays on wood charcoal within archaeological sites from the Puerto Peñasco area, Sonora. Mexico indicate use of the marine resources of the northern Gulf of California area during the Middle Archaic through the Late Archaic periods, ca. 3800 B.C.-A J). WO. The archaeological shell middens of the region are generally thought of as remains associated with Ceramic period Hohokam marine shell collecting forays with there being little consideration given to the likelihood of an Archaic period component being present. The importance of these age estimates is that they are derived from carbonized botanical remains rather than shell. Because of considerable variability in the carbon reservoir effect, age estimates derived from marine shell from the northern Gulf of California have limited reliability. The seasonality of collection is also considered through a preliminary study of stable oxygen isotope ratios in two shell samples. The results suggests that these shellfish were collected in the late fall, winter, and perhaps very early spring. [ABSTRACT FROM AUTHOR]

"Monarch Mystic Migration" is a lesson plan for elementary school students that focuses on the annual migration of monarch butterflies to Mexico. The lesson explores how the butterflies find their way and includes activities using geographer's tools like compasses and magnets. The lesson is designed to accommodate diverse learners and aligns with national standards in geography and science. The document provides detailed instructions for two class sessions, including engaging activities and vocabulary definitions. It also discusses the migration patterns of monarch butterflies, their navigation methods, and the cultural significance of their migration in Mexico. Additionally, the text mentions the conservation efforts related to the depletion of milkweed, the primary food source for butterfly larvae. [Extracted from the article]

Background and Scope Crassulacean acid metabolism (CAM) is an intriguing physiological adaptation in plants that are widespread throughout many ecosystems. Despite the relatively recent mechanistic understanding of CAM in plant physiology, evidence from historical records suggests that ancient cultures in the Americas also recognized the value of CAM plants. Agave species, in particular, have a rich cultural legacy that provides a foundation for commercially valued products. Here, we review that legacy and potential relationships between ancient values and the needs of modern-day climate adaptation strategies. Conclusions There are many products that can be produced from Agave species, including food, sugar, fibre and medicines. Traditional knowledge about agricultural management and preparation of plant products can be combined with new ecophysiological knowledge and agronomic techniques to develop these resources in the borderland region of the southwestern USA and Mexico. Historical records of pre-Columbian practices in the Sonoran desert and remnants of centuries-old agriculture in Baja California and Sonora demonstrate the climate resilience of Agave agriculture. Commercial growth of both tequila and bacanora indicates the potential for large-scale production today, but also underscores the importance of adopting regenerative agricultural practices to accomplish environmentally sustainable production. Recent international recognition of the Appellation of Origin for several Agave species produced for spirits in Mexico might provide opportunities for agricultural diversification. In contrast, fibre is currently produced from several Agave species on many continents. Projections of growth with future climate change suggest that Agave spp. will be viable alternatives for commodity crops that suffer declines during drought and increased temperatures. Historical cultivation of Agave affirms that these CAM plants can supply sugar, soft and hard fibres, medicines and food supplements. [ABSTRACT FROM AUTHOR]

Background: Agri-silvicultures (ASC) are biocultural practices procuring either the maintenance of wild diversity in predominantly agricultural spaces or introducing agrobiodiversity into forests. In the Mesoamerican region, ASC contribute to food sovereignty and territorial conservation and provide strategies for dealing with global changes. Previous inventories of ASC identified gaps in information about these systems in the Mexican Arid America region. This article raises the general question: How have human interactions between cultural, wild, and domesticated biodiversity in this territory? The particular questions in this paper are: (i) How have historical processes shaped human interactions between wild and domesticated biodiversity in the region? and (ii) What types of agri-silvicultures have emerged in Mexican Arid America since these relationships? Methods: We trace a methodological border where archaeologists have identified the Mesoamerican region to define our study area as Arid America northern of this line in Mexico. We analyzed agriculturalization processes in Arid America through a historical review. Then, we carry out an inventory of Arid America ASC based on academic papers and other documented experiences. We constructed a spatial database and a typology to understand what kinds of agri-silviculture occur in the region. Results: We identified several pre-Hispanic agri-silvicultural practices in the region, like hunting, fishing, terraces, gathering, and irrigation systems. The cultivation of native species of maize, beans, and squash even was registered. The Spanish colonization forced the agriculturization in arid northern Mexico, where itinerant hunting-gathering patterns predominated. In the twentieth century, the Green Revolution adopted this area as the principal setting for industrialized agriculture. The industrialized irrigated systems expansion and other political strategies provoked the simplification of productive landscapes. The practices that integrate wild and agricultural diversity systems were marginalized and invisibilized in such a context. Our research group proposes seven types of agri-silvicultural systems (natives agrisilvicultures, the oases agroforestry, Mesquite and Huisache ASC, homegardens and other traditional forms of agroforestry or agri-silvicultures). These agri-silvicultures provide food, medicine, fodder, and other contributions, as income to the families that practice them and protect native and exotic species. Discussion and conclusion: The agriculturization of the arid environments initiated during Spanish colonization and the subsequent modernizing projects shaped dominant actors and ideologies in the arid north of Mexico. However, aridity has favored ancestral and agroecological relationships between cultures and biodiversity, emerging and subsisting Arid American agri-silvicultures. These agri-silvicultures deserve to be understood, adopted, and adapted to new contexts. They could be essential alternatives in the context of environmental changes. [ABSTRACT FROM AUTHOR]

The oldest macaw specimen in Pre‐Hispanic Mexico and the southwestern United States was recovered in Cueva de Avendaños, Chihuahua, Mexico, at the base of the Sierra Madre Occidental. It dates to the Late Archaic/Early Agricultural period (1929–2057 cal BP). The head is the only preserved element of the macaw and it was mummified through natural causes. Research on this specimen examines its sex identification and its geographical range, questioning whether this specimen belongs to a local population living in the vicinity of the cave. A species distribution model over the last 2000 years was elaborated to ascertain the presence of military macaw in the study area. Our results show that the macaw was non‐local, sustaining the idea that the practice of early animal husbandry existed in the early stages of the Pre‐Hispanic world, and also suggest that a significant and rapid climate changes characterized the Holocene, affecting the military macaw's distributional range.

Accelerator mass spectrometry radiocarbon (AMS 14C) dates (n = 78) from human bone collagen were analyzed in the largest high-resolution chronology study to date at the ancient city of Teotihuacan in central Mexico (ca. AD 1–550). Samples originate from the residential neighborhood of La Ventilla, located in the heart of this major urban center. Here, a trapezoidal model using Bayesian statistics is built from 14C dates combined with data derived from the stylistic analysis of ceramics from burial contexts. Based on this model, we suggest possible refinements to Teotihuacan's ceramic chronology, at least within the La Ventilla neighborhood. We also explore the abandonment and reoccupation of La Ventilla after the political collapse of Teotihuacan in the Metepec and Coyotlatelco phases. Findings suggest that these ceramic phases began earlier than is currently projected and that the well-documented abandonment period of La Ventilla may have occurred more abruptly than originally estimated.

We compiled an updated database of all Agave species found in Mexico and analyzed it with specific criteria according to their biological parameters to evaluate the conservation and knowledge status of each species. Analyzing the present status of all Agave species not only provides crucial information for each species, but also helps determine which ones require special protection, especially those which are heavily used or cultivated for the production of distilled beverages. We conducted an extensive literature review search and compiled the conservation status of each species using mainstream criteria by IUCN. The information gaps in the database indicate a lack of knowledge and research regarding specific Agave species and it validates the need to conduct more studies on this genus. In total, 168 Agave species were included in our study, from which 89 are in the subgenus Agave and 79 in the subgenus Littaea. Agave lurida and A. nizandensis, in the subgenus Agave and Littaea, respectively, are severely endangered, due to their endemism, lack of knowledge about pollinators and floral visitors, and their endangered status according to the IUCN Red List. Some species are at risk due to the loss of genetic diversity resulting from production practices (i.e., Agave tequilana), and others because of excessive and unchecked overharvesting of wild plants, such as A. guadalajarana, A. victoriae-reginae, A. kristenii, and others. Given the huge economic and ecological importance of plants in the genus Agave, our review will be a milestone to ensure their future and continued provision of ecosystem services for humans, as well as encouraging further research in Agave species in an effort to enhance awareness of their conservation needs and sustainable use, and the implementation of eco-friendly practices in the species management.

Sucrose in its various forms has become an important part of our daily intake. Apart from sweetness, it also provides structure, and stability and plays important role in the appearance of the final product. Sucrose is widely used in the production of sweets, desserts, and beverages, however, the various effects of high consumption of sucrose, such as obesity, type 2 diabetes, and cardiometabolic disorders are of concern. Thus, in the present review, we have tried to summarize the usability of an alternative to sucrose. We explore the possibility of Agave, a native plant from Mexico, and its by-products (Agumiel, Agave syrup, etc) as a healthy alternative to sucrose in the food industry in this paper. This study uses Google scholar to review the history, properties, production, regulations, studies, and commercial adaptation of Agave in different food products. Chemical, physical, and biological properties are explored of the two most widely used varieties (Agave Tequilana & Agave Salmiana). The findings indicate that Agave has a long consumption history. Though the production is being regulated by the Mexican government, adulteration and fake labels are a concern. Recent animal studies have proved its safety, while long-term human benefits could be the scope of future studies. The authors conclude that Agave has good potential to replace sucrose shortly although long-term health benefits need acute exploration for it to be a suitable substitute for sucrose in order to reduce the risk of diet-related disorders.

New World households engaged in multiple forms of exchange: markets, redistribution, gifting, debt, reciprocity, and more. Determining the degree of prominence of each of these forms in ancient economies gives clues to the economic basis of leadership and the daily lives of households. A major method for inferring forms of exchange from household assemblages is Hirth's distributional approach. This paper applies the distributional approach to domestic inventories in two places where markets are unlikely: the Preclassic Maya in and around Ucí, Yucatan, Mexico; and Inka‐period settlements in the Upper Mantaro Valley, Peru. The data presented in this paper show an equitable distribution of fancy pottery among households of both high and low socio‐economic status in both areas. These somewhat unanticipated results could provoke several interpretations. At one extreme we could posit an important role for market exchange. At the other extreme, we could reject the logic of the distributional approach. This paper argues for a more circumspect track that uses additional lines of evidence to make inferences about incipient market exchange coincident with the rise of centralized leadership in the Maya area and poorly documented, possibly concealed market exchange nestled within Inka command economies.

With more than 200 species, the genus Agave is one of the most interesting and complex groups of plants in the world, considering for instance its great diversity and adaptations. The adaptations include the production of a single, massive inflorescence (the largest among plants) where after growing for many years, sometimes more than 30, the rosette dies shortly afterward, and the remarkable coevolution with their main pollinators, nectarivorous bats, in particular of the genus Leptonycteris. The physiological adaptations of Agave species include a photosynthetic metabolism that allows efficient use of water and a large degree of succulence, helping to store water and resources for their massive flowering event. Ecologically, the agaves are keystone species on which numerous animal species depend for their subsistence due to the large amounts of pollen and nectar they produce, that support many pollinators, including bats, perching birds, hummingbirds, moths, and bees. Moreover, in many regions of Mexico and in the southwestern United States, agaves are dominant species. We describe the contributions of H. S. Gentry to the understanding of agaves and review recent advances on the study of the ecology and evolution of the genus. We analyze the present and inferred past distribution patterns of different species in the genus, describing differences in their climatic niche and adaptations to dry conditions. We interpret these patterns using molecular clock data and phylogenetic analyses and information of their coevolving pollinators and from phylogeographic, morphological, and ecological studies and discuss the prospects for their future conservation and management.

Coordinated with excavations at two prehispanic sites in the eastern arm of the Valley of Oaxaca, Mexico, we documented a diversity of economically useful plants at both localities. Many plants that abound at El Palmillo and the Mitla Fortress are used locally as food, medicine, and in ritual activities. These hilltop settlements were abandoned during the prehispanic era and never resettled, leaving relict floral communities that were once tended by their prehispanic inhabitants. A comparison of plant communities at El Palmillo, the Mitla Fortress, and other locales in the Valley of Oaxaca illustrates the higher incidence of xerophytic plants in the drier eastern (Tlacolula) arm of the valley, with the greatest abundance in archaeological contexts. These findings affirm the importance of a broad array of succulents (especially Agave spp.), yucca, and cacti for the region's inhabitants, thereby helping account for the dense prehispanic populations that resided there.

We present three new analyses of existing data from past fieldwork at Teotihuacan. First, we confirm and refine the wealth-based housing typology of Millon's Teotihuacan Mapping Project (TMP). Second, we analyze the spatial configurations of excavated compounds, using network methods to identify the size and layout of individual dwellings within walled compounds. Third, we use those results to generate the first population estimate for the city based on measurements from the TMP map. We extrapolate the average sizes of dwellings from excavated compounds to the entire sample of mapped residences as depicted on the TMP map of the city. We generate a range of population estimates, of which we suggest that 100,000 persons is the most reasonable estimate for the Xolalpan-Metepec population of Teotihuacan. These analyses show that legacy data from fieldwork long past can be used to answer research questions that are relevant and important today. [ABSTRACT FROM AUTHOR]

In 2009, the U.S National Park Service instituted tours accompanied by armed guards to areas of Organ Pipe Cactus National Monument, which abuts the U.S.- Mexico boundary in southern Arizona. These areas, like the majority of the park's lands, had been closed to the public since August 2002, following the shooting death of National Park Ranger Kris Eggle-allegedly by drug smugglers from Mexico. The re-opening reflected the U.S. Border Patrol's and National Park Service's "retaking" of parts of the park that had been "lost" to unauthorized migrants and drug traffickers. This article explicates the tours' origins, illustrating how they connect present and past in relation to the making of the U.S.-Mexico borderlands, and Organ Pipe Cactus National Monument as a territory of "nature." In doing so, the article shows that the militarized tours (which ended in September 2014, with the entire park's re-opening) are the understandable extension of the park's doubly colonial logic-as imperialized/settler-colonized space and as the embodiment of a stark division between humans and nature. Overcoming such violence and facilitating the thriving of humans and other-than-humans in the space of OPCNM requires a reworking of "nature" and territory-as well as of the associated human identities.

This article surveys research in Northwest Mexico (Sonora and Chihuahua), with an emphasis on the Early Agricultural period to the Late Prehistoric period. Middle range societies that are diverse in scale and organization characterize this region. Significant advancements in our understanding of these societies have been made in recent years, but substantial challenges remain in building interpretative frameworks that account for both regional diversity and incorporate macroscale interactions. Topics covered in this review include the adoption of agriculture, population movements, bases of social differentiation, and interactions between organizationally disparate groups. These issues demonstrate the relevance of the Northwest to research on the organization of middle range societies. [ABSTRACT FROM AUTHOR]

This special issue of the Journal of Archaeological and Anthropological Sciences provides a broad overview of the foods and foodways at a premier example of urbanism in the pre-Hispanic New World, the ancient metropolis of Teotihuacan, Mexico. One of the grand challenges of reconstructing ancient urban foodways is determining the social, economic, political, and ideological factors that enabled the production, distribution, consumption, and discard of food. In this volume, we define foodways as a social process, reenacted via the daily interactions between individuals. By bringing together scholars of Teotihuacan that use diverse methods and scales of analysis, we are able to provide a synthetic review of Teotihuacan foodways by summarizing the findings of each of the contributors and contextualizing their results by embedding them within knowledge gained from the long history of investigation at the site.

ABSTRACT Objective To analyze the origin, structure, relationships, and recent admixture in Mexican Native groups based on 15 STRs commonly used in human identification. Methods We analyzed 39 Mexican Native population samples using STR databases based on the AmpF lSTR® Identifiler kit ( n = 3,135), including Mexican-Mestizos (admixed), European and African populations, as reference. Results Based upon effective population size (Ne) differences, Native groups were clustered into three regions: i) Center-Southeast groups, characterized by larger Ne, migration rate (Nm), genetic diversity (He), and relative homogeneity principally in the Yucatan Peninsula; ii) Isolated southern groups from Chiapas and Oaxaca, characterized by lower Ne, Nm, and He (i.e. higher isolation and genetic differentiation); iii) North-Northwest groups, which are similar to the previous group but are characterized by generating the widest gene flow barrier in the Pre-Hispanic Mexican territory, and currently by elevated admixture in some northern Native groups. Despite the relative congruence between genetic relationships with cultural, linguistic, geographic criteria, these factors do not explain the present-day population structure of Native groups, excepting in those linguistically related to the Mayan that show higher homogeneity. The Isolation by distance model was demonstrated at long distances (>1,500 km), whereas geographic isolation stands as a determining factor to avoid both non-indigenous admixture and bottleneck processes. Conclusions Different dynamics of gene flow and drift were observed among Mexican Native groups, highlighting the geographic barriers (mountains, canyons and jungle regions) as the main factor differentiating Pre-Hispanic populations, and eventually helping to avoid Post-European contact admixture and population bottleneck.

Intensive agriculture was a key feature in the development of early complex societies in the Basin of Mexico. In this paper, I review the theoretical underpinnings of archaeological understandings of agriculture change, its relationship to culture change, and how these theoretical perspectives have shifted between top-down and bottom up perspectives. Next I examine current knowledge of intensive agriculture within the dynamic context of the Formative or Preclassic period. The paper concludes with a discussion of how our models and theories of the complex interplay between intensive agriculture and political economy to explain the change from village-based societies to states and cities outstrip available data in the basin.

This article integrates geological, biological, ethnographic, and archaeological lines of evidence to reconstruct fishing patterns between approximately 4100 and 500 BC in the northern Gulf of California. In addition to shell collecting along the coast, several species of fish were captured, mainly endemic sciaenids of the upper gulf. Our study focuses on the northern Sonoran coast where recent archaeological studies have discovered scores of otoliths (fish ear bones) in archaeological contexts. We report the species composition (chano, corvina, totoaba) and relative size of the prehistoric catch and discuss the modern biology of these species known to inhabit this area. Our evidence suggests that this area offered an important resource for Archaic hunters and gatherers who were drawn here to exploit fish at certain times of the year. Following sea level stabilization around 6,000 years ago, particular geomorphic settings provided opportunities to easily harvest large quantities of fish by spearing, netting, or hand catching them.

Jason De León's Undocumented Migration Project and Valeria Luiselli's Lost Children Archive are two archival studies of the U.S.-Mexico border crisis that challenge hegemonic practices of documentation, including those historically privileged by the U.S. Department of Homeland Security, human rights activism, and the field of digital humanities alike. Though De León and Luiselli have participated in human rights work while identifying migrant corpses and collecting detainees' testimonies, both use counter-mapping to interrogate the dominant humanitarian move of restoring visibility and voice, or sight and sound, to human victims. After investigating the ways in which De León and Luiselli privilege visual and sonic counter-mapping, respectively, I model a more multi-sensory counter-mapping practice. Though this practice remains far from perfect, I argue that such digital counter-mapping crosses sight and sound in ways that defy historical divisions among humans and nonhumans. Accordingly, it decenters humans as the sole victims of the U.S.-Mexico border crisis. Investigating methods for counter-mapping and proposing a more multi-sensory practice. [ABSTRACT FROM AUTHOR]

While changing views of the sociopolitical history of the northern Maya lowlands now recognize that Chichen Itza's emergence as a major polity on an unprecedented scale occurred during the Terminal Classic period, rather than the Early Postclassic period, the ramifications of significant chronological overlap between Chichen Itza's rise and the demise of neighboring polities have been largely unexplored. The ancient Maya center of Xuenkal, located in the Cupul region about 45 km northeast of Chichen Itza, is one of the few known interior sites to contain substantial (and discrete) Cehpech and Sotuta occupations. The Proyecto Arqueológico Xuenkal (PAX) was initiated in 2004 to elucidate Chichen Itza's role in the history of the Cupul region and what role local Xuenkal elites may have played in negotiating regional political dynamics. As with many surrounding centers, it appears that Xuenkal's occupational history reached its zenith with the Late Classic–Terminal Classic Cehpech ceramic sphere. However, unlike neighboring sites associated with Cehpech, such as Ek' Balam or Yaxuna, Xuenkal also contained a substantial Sotuta settlement concentrated within the site core during the Terminal Classic period. These populations adapted into an evolving regional economy by dramatically increasing household production as compared to Late Classic groups. While Sotuta households were tightly integrated into Chichen Itza's regional economy, evidence for their direct state control is not readily apparent. We suggest that the relationship between Chichen Itza and regional communities was more dynamic than current models contend, and that Chichen Itza's political machinations across the peninsula must be considered in local contexts that varied across households, communities, and regions.

Ebtun, Kaua, Cuncunul, Tekom, and Tixcacalcupul are a group of related communities on the Yucatán peninsula described in the corpus of Maya-language documents known as The Titles of Ebtun. In this paper I explore transformations in agrarian practice and material expressions of identity after the Spanish invasion by analyzing archaeological variation in the life histories of places over the last 500 years. As new plants, animals, and technologies were adopted, landscape organization changed, and locales took on new meanings. Ebtun's landscape reflects a historically contingent process that has transformed place and identity, fostering autonomy of cultural practice and renewal of tradition. [ABSTRACT FROM AUTHOR]

Differences in land use and land cover often coincide with social and political borders. Using vegetation indices and a visual inspection of Landsat imagery, we consider a rural section of the central Arizona-Sonora border dominated by government-owned land on the U.S. side and seek to understand where and why cross-border land cover continuity exists in some places while distinction exists in others. Land cover distinctions are attributed largely to differential population and economic pressures in the two countries, but are also exacerbated by social and political distinctions. By contrast, historical relations, common use of the land, and relative remoteness provide cross-border homogeneity in land use and land cover in rural areas, especially on the Tohono O'odham reservation.

En el actual territorio de Sonora, México, la adopción de la agricultura y el sedentarismo estuvieron acompañados de un profundo cambio reflejado tanto en la emergencia de la cerámica como en el patrón de asentamiento entre los años 200 a 1450 d.C. Uno de estos desarrollos culturales es lo que ahora conocemos como la cultura Trincheras. Se piensa que hacia el 900 d.C. el paisaje cultural fue transformado por la aparición de asentamientos en los cerros que se conocen genéricamente como cerros de trincheras. Parecería que el emplazamiento de estos sitios no fue parte de un proceso homogéneo en su presente, sino el producto de sucesos interconectados con su pasado. En ellos, la memoria colectiva pudo haber tenido un rol fundamental en los rechazos y permanencias observadas en la cultura material. El objetivo del presente artículo es discutir las características de dos cerros de trincheras y cómo éstos pudieron haber sido el referente en la memoria colectiva de la sociedad prehispánica del noroeste de México durante el 900–1450 d.C.

Gardens are an important part of the environment as they play multiple roles and are central to the lifestyle and economy of many communities. The investigators use qualitative methods to explore patterns and perceptions about changes in gardening and cultivation in the community of Maycoba, Mexico. Maycoba is home to a large community of Pima Indians, an Indigenous population genetically prone to diabetes. Pima Indians living in the United States have been shown to have an extremely high prevalence of diabetes, but the genetically comparable Pimas in Maycoba, Mexico, were found to have little diabetes in the early 1990s. The authors examine home gardens and other cultivation in the area as an element of a changing environment and lifestyle during the past 15 years. Methods include interviews and focus groups. Preliminary findings are presented in this paper. [ABSTRACT FROM AUTHOR]

Mission Santa Catalina was founded on the margins of the Spanish colonial frontier in northern Baja California, but over time it became an important place in the indigenous landscape of the region. Dominican friars established the mission at a crossroads of native interaction, and recent archaeological, archival, and ethnographic research suggests that indigenous mission neophytes continued to engage in dynamic social and economic relationships with other native groups throughout the colonial period. At the same time, however, the diverse native peoples who lived at Santa Catalina formed new bonds to each other and to the lands around the mission itself. Together, these two processes suggest that the mission's neophyte population was not isolated from the broader indigenous landscape, and that although it was marginal from the point of view of the Spanish, Santa Catalina was--and continues to be--an important place in native Baja California.

Western Mexico is vast and geographically diverse and has received far less attention compared to other areas of Mesoamerica. Research over the past decade allows the definition of four major subregions characterized by cultural factors and distinct historical trajectories. A large proportion of the research in western Mexico is still culture-historical in nature, oriented toward establishing chronologies and relationships between regions. But along with a number of recent efforts toward synthesis and consolidation, current theoretical research contributes to the study of mortuary patterns and social organization, alternative forms of social complexity, agricultural intensification, empire formation, state involvement in the economy, human-land relationships, and the interlocking relationship between migration and sociopolitical reorganization.

The article examines the Colorado River's natural and cultural systems and the outlook for the river's viability as a renewable water source that will support human habitation in the region of the Colorado River Basin. The discussion focuses on the influence of humans on the natural world in the American Southwest, water use, sustainability, and environmental values. The disappearance of the Santa Cruz River, water consumption in cities such as Tucson in Arizona, water extraction from aquifers under the Sonoran Desert, and the occurrence of subsidence after the removal of groundwater are mentioned.

Although the topic has received recent attention, relatively little is known about how pre-Hispanic Mesoamerican communities were internally organized and interconnected. In this paper, we examine that question from the perspective of the Classic-period settlement of El Palmillo, in the Valley of Oaxaca, Mexico. Previous studies of the valley have postulated that communities often were (and still are) subdivided into barrios, although the modes of integration for those segments are less fully defined. Along these lines, we have previously identified commoner and higher-status houses at El Palmillo (along with associated artifactual and architectural inventories). We also have noted that different commoner houses were involved in distinct suites of craft activity, thereby indicating a degree of economic interdependence among these units. Here we expand our analysis to domestic offerings, which we found to vary across the excavated houses. Adapting a perspective from Durkheim's distinction between mechanical and organic solidarity, we find an expected organic (hierarchical) relationship between the offering assemblages of the higher-status residences and the offerings in commoner house lots. At the same time, we see another axis of variation in domestic offerings that appears more organic (nonhierarchical) in nature. The latter axis of variation at El Palmillo has a clear spatial component, in support of previous hypotheses that barrios or spatially defined social segments were important in Valley of Oaxaca pre-Hispanic communities. At El Palmillo, the definitional features of these social segments appear to have been ideological as well as economic. [ABSTRACT FROM AUTHOR]

Residents of Mayapan produced and consumed metal artifacts through long-distance commercial exchange networks in the Postclassic Mesoamerican world system. In this paper, I perform a stylistic and typological analysis of metal artifacts and debris from lost-wax casting from recent excavations at Mayapan, with reference to previously excavated collections by the Carnegie Institution of Washington, DC. The distribution of metal artifacts suggests that metal objects were not sumptuary goods restricted to elites, but luxury goods availble to those who could afford them. I then compare Mayapan with other sites in the Postclassic Mesoamerican world system that were involved in the interregional distribution of metal artifacts. Although Mayapan did not have local sources of native metal or a longstanding traditions of metalworking, it was able to use its economic influence in the world system to obtain and create metal objects specific to its needs.

The expansionary strategies of Teotihuacano political leaders involved the large-scale manufacture of weaponry and the production of ceremonial items representative of a coherent suite of symbols expressing themes of warfare and sacrifice. Recent excavations at the Moon Pyramid demonstrate that such production activities were undertaken next to the monument, where obsidian was reduced into dart points and eccentrics linked to militarism and sacrificial practices in the art and archaeology of the city. These craft production activities were likely directly administered by state functionaries and formed part of the physical and ideational bases of state political authority. The finished products served as means of direct military coercion and symbolic reification of state authority, materialized through the militaristic offering complexes within the major temples of the city. This study presents a detailed technological analysis of the production activities and contextualizes their social significance by examining their symbolic manipulation in the art and sacrificial offerings of Teotihuacán.

Father Miguel Venegas' 1739 Obras Californianas is the most extensive and detailed document covering the first forty years of the Jesuit period in Baja California. In addition to providing discussions of historical events, Venegas wrote extensively on the natural world and on indigenous cosmology, social networks, and lifeways. The section translated and annotated here includes the bulk of Venegas' Writing on Isla Cedros and its native people. The island, located on the Pacific Coast of central Baja California, was home to a large, maritime-adapted indigenous society. The period of time (1728-1732) covered in this section of the much larger Venegas manuscript details the tragic end of Cedros Island's indigenous society, but preserves an account of their culture that is of inestimable value. The annotations included provide not only clarifications of meaning, but critical evaluations of the text and of the significance of particular passages within the larger context of Baja California indigenous and colonial history.

Nahuatl represents a relatively recent extension of the Uto-Aztecan language family into Mesoamerica. Ethnohistorians have linked Nahuatl's arrival to the historically attested migrations of nomadic people into central Mexico in the last centuries before the Spanish Conquest. Archaeologists have tended to treat migration as an explanation for a change in material culture rather than a social question to be examined theoretically. We approach this migration through the comparison of multiple data sets and conclude that what has previously been treated as a historical event is instead part of a longer term process tying together Mesoamerica's northern periphery with its highland core. While we find that certain themes from migration theory are reflected in this preindustrial migration as well, other variables are unique and bode well for archaeology's ability to address and contribute to theoretical issues relating to migration.

Paleoecology of Laguna Babícora, Chihuahua, Mexico was reconstructed using ostracode faunal assemblages and shell chemistry. The paleolimnological record is used to show the magnitude of paleoclimatic changes in the area from 25,000 years to the present. Faunal assemblages consist of four species of the genus Limnocythere: L. sappaensis, L. ceriotuberosa, L. bradburyi and L. platyforma, all associated with Candona caudata, Candona patzcuaro and Cypridopsis vidua. A paleosalinity index developed from these assemblages indicates that the lake's salinity fluctuated frequently from oligo- to meso-haline conditions during the last ∽ 25,000 years. This pattern and low salinity range are in good agreement with modern TDS (here used as an indicator of salinity) values recorded from 26 wells and one spring from the area (258–975 mg l−1). To estimate paleotemperature we examined the trace element content (Mg/Ca ratios) from individual valves of L. ceriotuberosa and L. platyforma, the two species most commonly recorded in Laguna Babícora. Shell Mg/Ca ratios of 204 specimens of these two species were used to estimate water temperature (Mg/Ca) by means of experimental standard coefficients. Our data show that paleowater temperature ranged from 5.6–21.3 °C (with 2σ values ranging from 0.2–4.8 °C), which suggest a close correlation with atmospheric temperatures around the lake. These results are in good agreement with a modern mean winter temperature (3.5 °C) and mean summer temperature (20 °C) recorded in the area between 1970 and 1980. [ABSTRACT FROM AUTHOR]
