This study investigates the impact of intraregional conflict on food security and subsistence practices in the Central Illinois River Valley (CIRV) during the Mississippian period, particularly between AD 1200 and 1400, a time characterized by escalations in intergroup violence. Utilizing integrated faunal and botanical datasets from two critical archaeological sites – the Lamb site, representing the preconflict phase, and the C. W. Cooper site, indicative of the conflict onset phase – this research elucidates how prolonged warfare necessitated substantial adaptations in subsistence strategies among CIRV Mississippian communities. While much previous research has centered on elite aspects of Mississippian warfare, this study shifts the focus to the broader societal impacts on the daily lives of residents of the CIRV. Findings demonstrate significant shifts in foraging behaviors and resource utilization patterns, reflecting strategic responses to the challenges and hazards posed by persistent warfare. By highlighting the adaptability of these communities in the face of warfare and environmental stressors, this research contributes valuable perspectives to the anthropological understanding of the interrelations between warfare and food systems.

The Trincheras tradition thrived in the Altar, Magdalena, and Asunción-Concepción valleys from 400 to 1450 CE. In the early twentieth century, archaeologists proposed that the Trincheras people were hunter-gatherers until around 1300 CE. This study investigates whether the plant use practices of the Trincheras tradition remained consistent across different regions and through time. I compare archaeological and macrobotanical data recovered at three Altar Valley Trincheras sites dated to ∼750–1300 CE (El Póporo, La Potranca, and San Martin) and integrate data from La Playa (400–650 CE) and Cerro de Trincheras (1300–1450 CE). The results revealed that the Trinchereños were agriculturalists from 400 to 1450 CE, disproving twentieth-century archaeologists' hypothesis. Between 1050 and 1300 CE, the ubiquity values of maize were the greatest at Trincheras Altar Valley sites. However, after relocating to the Magdalena Valley around 1300 CE, the percent presence of maize decreased, while that of agave and foraged foods increased. [ABSTRACT FROM AUTHOR]

Earth ovens are a ubiquitous feature of eastern North America, used throughout many cultures and periods, leaving a highly visible signature of habitational life. This study focusses on one of the four uniquely outsized earth ovens from the center of a woodhenge at Hopewell Mound Group, the type site of the Hopewell culture. Cleaned of artifacts and fire-cracked rock, this feature required specialized analysis to shed light on its function: macrobotanical methods of seed identification and wood charcoal analysis along with phytolith and soil micromorphological analysis. These analyses create a holistic picture of the earth oven, the woodhenge, and the nature of feasting and ritual at Hopewell Mound Group, along with a snapshot of the paleoenvironment. Results show ritual use of ash wood (Fraxinus sp.), Eastern Agricultural Complex seeds seasonally timed with a summer solstice ritual, and grass leaf phytoliths deposited deeper than the surrounding natural strata. Feasting at this site seems to be focused on feeding large numbers of people, as opposed to a small set of competitive elites. [ABSTRACT FROM AUTHOR]

Numerous oral histories and substantial ethnographic evidence illustrate how plant species, communities, and even landscapes were extensively managed and cared for by ancestral communities in the Pacific Northwest. Camas (Camassia spp.) is one such cultural keystone plant, common from the Pacific Ocean to the Rocky Mountains, with numerous records describing its role as a staple food for many Northwest peoples. Supporting deep time archeological evidence for such management or stewardship practices, however, has remained elusive. In this paper we analyze archived collections of archeological camas bulbs from 11 sites across the Willamette Valley, Oregon to demonstrate people began preparing camas within earth ovens by approximately 8000 calendar years before present and deliberately harvesting sexually mature camas plants circa 3500 calendar years before present. We compare these findings with climatological, palynological, and fire history reconstructions to discuss stewardship strategies for camas and associated plant communities through time at the population, community, and landscape levels. These findings confirm and expand upon Indigenous knowledges as well as offer time-tested methods for cultural keystone conservationists seeking to revitalize traditional plant stewardship practices throughout this region and beyond. This "camas case study" also offers another example of a human-plant symbiotic relationship, expanding our knowledge of plant food pathways, processes, and mutualisms. [ABSTRACT FROM AUTHOR]

How do we identify ancient fields and farming systems in areas where the same spaces of cultivation have been used repeatedly over thousands of years? In the limestone karst landscapes of northern Dalmatia, on the Adriatic coast of Croatia, drystone field walls, terraces, and cairns are common features that attest to generations of working the land for agriculture. While confounding archaeological objects due to complex histories of reuse, drystone terraced field systems throughout the Mediterranean are believed to have roots in ancient and prehistoric land use. Against this backdrop, this paper works to better understand the dynamic patterns and outcomes of field "recycling" through multiple lines of evidence for long‐term changes in cropping patterns and agroecology in multi‐millennial agricultural landscapes of northern Dalmatia. We compare archaeobotanical data from the Ravni Kotari plain to documents of preindustrial land use from the 1826 Franciscan cadastre. We also draw upon contemporary observations of traditionally managed, semi‐wild olive groves on the nearby Adriatic island of Ugljan to better understand the land‐use legacies inherent in the landscapes of northern Dalmatia today. These data show that, despite a relatively static agricultural built environment of field walls and terraces, Dalmatian communities held historically dynamic relationships with domesticated and wild plant ecologies. Prehistoric integration of cereal agriculture with wild forest resources appears to have shifted to commercial‐scale domesticated arboriculture in the Classical period, leaving a multifaceted legacy of commercial agriculture, traditional farming, and rewilding among the contemporary cultural landscapes of Dalmatia.

The archaeological record of the Lower Mississippi Valley represents a long history of Indigenous people making wide and variable use of the region's exceptionally rich ecosystems. Often, archaeological interpretations of these interactions focus on subsistence and do not take into consideration non-food uses of plants and animals. Our excavations at two Coles Creek (AD 750–1000) mound centers, Feltus and Smith Creek, yielded curious concentrations of sweetgum (Liquidambar styraciflua) in addition to the expected suite of plants. We first discuss the archaeological context of sweetgum on these sites, then outline our methods of identifying the plant in archaeological samples. We detail the process of identifying sweetgum both in-field and from flotation and water-screening samples and provide identification criteria that can be used by other analysts. Finally, we review what we know about sweetgum use from the broader archaeological, ethnohistoric, and ethnographic records. Drawing these lines of evidence together, we synthesize pre – and post-colonial ethnobotany to hypothesize about how and why Coles Creek people used this plant in ceremonial activities taking place at mound centers.

In this study, we assess competing interpretations of a burnt ceremonial structure from the terminal Middle Formative period (ca. 300–100 BCE) by analyzing the stepped platform mound at Chiripa, Bolivia, through a systematic reconstruction of the fire that destroyed it. We developed a model of potential fire pathways, their social contexts, and material indicators. Our approach contrasts incipient fires from accident or arson to planned fires initiated for functional or social ends. We assessed these pathways for the Chiripa mound fire through experimental, geoarchaeological, faunal, and botanical data. Experiments were aimed at deducing the temperature, duration, and oxidation conditions of the fire. The fire temperature and duration were approximated from geoarchaeological analyses of construction materials in comparison with controls, and thermal alteration of faunal bone. Fuels were reconstructed through paleoethnobotanical analysis of charred remains from discrete areas within the burnt structure. We conclude that an intentional fire burned the structures on the Chiripa mound to temperatures of 700 °C or higher under oxidizing conditions for several hours. The pattern of heat-altered materials recovered would have required a substantial supplemental fuel load. At the 3840 masl elevation of Chiripa, the effective control of a high temperature oxidizing fire demonstrates technical expertise in fire management. Our findings indicate the fire appears intentional, likely a ritual event. We believe the structures were burned to facilitate a socio-political change during a period of social transition at the end of the Middle Formative period in Bolivia. [ABSTRACT FROM AUTHOR]

Paleoethnobotanical remains from basketry and cordage from the Paisley Caves offer an opportunity to explore how people engaged with plant communities over time. Fiber identification of textiles, together with radiocarbon dating, contributes new information about landscape use within the Summer Lake Basin. Expanded marshlands during the terminal Pleistocene / Early Holocene created suitable plant communities ideal for fiber technology, specifically wetland monocots and herbaceous dicots-including dogbane and stinging nettle-by 11,000 years ago. This technology is key to subsistence activities and craft production throughout the Holocene. Despite climatic events during the Middle Holocene, in which people transitioned from caves to sites centered on lakeshores and wetlands, the suite of fiber plants and their technological application remains constant. During the Late Holocene, bast fiber material diversified with the addition of flax and milkweed. The presence of flax in particular, a high-elevation plant, may reflect the increased use of upland root collection areas as populations increased. This research provides long-term data on culturally significant native plants used in the manufacture of fiber-based textiles over the last 14,000 years. [ABSTRACT FROM AUTHOR]

Cultural land-use is an important driver of ecosystem change, influencing the composition of species across landscapes and through time. Recent research in northwestern North America has shown that historical Indigenous land-use and forest management has resulted in relict forest gardens dominated by edible fruit, nut, and berry producing trees and shrubs – many of which continue to grow adjacent to archaeological village sites today. Our research combines archaeological and ecological methods to better understand the historical ecology of seven forest gardens in the Pacific Northwest. Vascular plant communities at all sites are evaluated for distinctiveness using ANOSIM, NMDS, and indicator species analyses. We identify 15 forest garden indicator species, all of which are culturally significant edible fruit or root-bearing species. We then present the results of an intensive historical-ecological study of one site in Laxyuubm Gitselasu (Ts'msyen). Paleoethnobotanical data, soil and tree ring analyses, and radiocarbon dates show that forest management in the Gitsaex forest garden of Gitselasu pre-dates settler colonialism and shows that people likely modified soils and otherwise enhanced their immediate environment to increase the productivity of desired plant species. Given the importance of Indigenous peoples' role in sustaining forested foodsheds, there is an ongoing and urgent need to support their revitalization and management and better understand the integrated cultural practices and ecological processes that result in these vast cultural landscapes.

We focus on pre-Columbian agricultural regimes in the Maya Lowlands, using new datasets of archaeological wood charcoal, seeds, phytoliths, and starch grains; biological properties of plants; and contemporary Indigenous practices. We address inherited models of agriculture in the lowlands: the limitations of the environment (finding more affordances than anticipated by earlier models); the homogeneity of agricultural strategies (finding more heterogeneity of strategies across the lowlands than a single rigid template); the centrality of maize in agriculture (finding more reliance on root crops and tree crops than historically documented); the focus on the milpa system as food base (finding more agroforestry, homegardening, horticulture, and wild resource management than previously documented); the dominance of swidden strategies in agricultural practices (finding more diverse practices than accounted for in most models); and the foregrounding of maize crop failure in collapse models (finding more evidence of resilience and sustainable agricultural practices than predicted).

The Late Classic Maya village of Joya de Cerén's extraordinary preservation caused by the Loma Caldera volcanic eruption around 650 CE allows for a unique opportunity to understand what plant species ancient Mesoamerican farmers utilized in their daily lives for food consumption, medicinal applications, fuel, and construction purposes. While Cerén has unusually good preservation of earthen-made household structures, gardens, and extensive outfields growing maize, manioc, and numerous weedy species, this article will review the collection of anthracological remains recovered from excavations at the site since 1978. Wood charcoal recovered via flotation samples taken throughout the archaeological site reveal the surrounding ecosystems that Cerén villagers would have exploited to regularly obtain their wood resources. Additionally, various fruit trees were cultivated within the village center, as evidenced by limb, trunk and fruit impressions preserved as plaster casts. The data collected from the long history of archaeobotanical research at Cerén suggests that these ancient rural agriculturalists practiced sustainable land management strategies and incorporated a diverse assemblage of tree species into their daily practices. The ancient agriculturalists effectively coped with an ever-changing landscape and opportunistically established their settlement in a biodiverse setting that had plentiful resources from a range of ecosystems available for their daily needs.

The Silk Road is a modern name for a globalization phenomenon that marked an extensive network of communication and exchange in the ancient world; by the turn of the second millennium AD, commercial trade linked Asia and supported the development of a string of large urban centers across Central Asia. One of the main arteries of the medieval trade routes followed the middle and lower Zarafshan River and was connected by mercantile cities, such as Samarkand and Bukhara. Bukhara developed into a flourishing urban center between the fourth and sixth centuries AD, served as the capital of the Samanid court between AD 893 and 999, and remained prosperous into the Qarakhanid period (AD 999–1220), until the Mongol invasion in AD 1220. We present the first archaeobotanical study from this ancient center of education, craft production, artistic development, and commerce. Radiocarbon dates and an archaeological chronology that has been developed for the site show that our samples cover a range between the third and eleventh centuries AD. These samples from Bukhara represent the richest systematically collected archaeobotanical assemblage thus far recovered in Central Asia. The assemblage includes spices and both annual and perennial crops, which allowed Sogdians and Samanids to feed large cities in river oases surrounded by desert and arid steppe and supported a far-reaching commercial market in the first millennium AD.

Site densities in Mississippi's Upper Yazoo Basin indicate that populations increased in numbers during the Late Woodland period. Plant remains recovered during salvage operations at the Oliver site in Coahoma County contribute to a database confirming the importance of both wild and cultivated resources for Baytown people of that time. Because the samples reported here were retrieved by water screening rather than flotation, small seeds are uncommon. Still, all four starchy seed taxa and both oily seed crops belonging to the Eastern Agricultural Complex were recovered, along with the unidentified grass known as Type X. The abundance of acorn shell at Oliver and nearby sites with Baytown components calls for more inquiry into how acorns were accessed, processed, cooked, and eaten. We call attention to the pottery that occurs in high frequencies, suggesting that much of it was used to store, cook, and leach tannins from acorns, as well as to prepare other foodstuffs. Discussions of early agriculture in the Yazoo Basin once focused on corn, subsequently incorporating pre-corn native crops. We propose an expanded concept of food production that includes management of nut tree groves and tending of gardens to partially explain the thickly populated Late Woodland Delta landscape.

This report presents an experiment in which four starch sampling methods are compared in order to identify the most successful and effective technique for starch extraction from large groundstone and milling features in the field. Testing archaeological specimens in situ is necessary when the artifact is too large or cumbersome to bring back to a laboratory. In addition, preliminary testing in the field allows researchers to obtain quick results thatprovides guidance for ongoing excavation and sampling methods.

My research investigates the human-environmental interactions of Prehispanic peoples in the Arenal region of Costa Rica. This area is an ideal location to look at resilient practices in the past, since domestic settlements in Arenal persevered through powerful volcanic eruptions that impacted the landscape every few centuries. As a paleoethnobotanist, I collected soil samples that will help reconstruct the past foodways and environmental management strategies of these past peoples over time through the study of archaeological plant remains preserved within an ancient domestic structure (La Chiripa) that was situated near the Arenal Volcano. At this site, distinct ash deposits distinguish between periods of human occupation, with abandonments, ecological recovery, and then re-occupations after each volcanic eruption, spanning from 1450 BCE to 1530 CE. In 2018, supported by Stahl funds, I constructed a flotation machine and processed the soil samples collected from this ancient household structure in order to recover any plant remains that were preserved below the ground surface. With a theoretical framework of practice theory, historical ecology, and household archaeology, my archaeobotanical research will examine the dynamics of residential groups procurement, production, redistribution, and transmission of goods and cultural practices to subsequent generations over thousands of years of archaeological representation in this volcanic setting. This dissertation research will provide invaluable information regarding ancient household practices, long-term residence stability, and environmental resilience in Pre-Columbian Central America.

Tell Khamîs, an archaeological site of the Syrian region of Upper Jazeera, is 3 km east of the Euphrates and 31 km from Yarâblûs (ancient Karkemiš); archaeological excavations determined seven different levels (Early Bronze, Middle Bronze, Aramaic, Assyrian, Persian, Hellenistic, and Islamic). This study aims to identify plant remains recovered during the excavation of the site and to place them within the chronology of Tell Khamîs and in the context of the archaeobotanical evidence for the Upper Euphrates. A total of 88 sediment samples were collected, and seeds, recovered via flotation, were identified using optical and SEM microscopy. A total of 20,606 whole remains and 37,646 fragments belonging to 92 taxa and 35 plant families were identified. Seed lists were compared with those from other sites, and the results were analyzed using multivariate techniques. Barley is particularly noteworthy for the number of remains; this species was found in 49 different samples, notably, in a silo of about 4 m3 in volume. Middle Bronze Age and Assyrian levels are the richest in remains; the site presents a maximum of documented activity in the Middle Bronze Age period, and the most interesting taxa from a paleoenvironmental and cultural point of view are represented by one or a few seeds.

Indigenous people have profoundly influenced terrestrial and marine ecosystems by modifying coastal habitats to increase the productivity of target species and altering local biotas through their harvesting practices. In some cases, these actions led to local resource depression, while in other instances, Indigenous people engaged with terrestrial and marine resources in sustainable ways, increasing the resilience of ecosystems. In this paper, we interrogate human-environmental relationships that span the last ∼7,000 years of Indigenous engagement with coastal resources on the central California coast. Through a historical ecological framework, we assess how Indigenous peoples interacted with terrestrial and marine ecosystems differently across space and through time. In the Middle Holocene, the region’s archaeology is typified by mobile populations using diverse terrestrial and marine resources. By the Late Holocene, Indigenous peoples intensified their economies towards a limited number of marine and terrestrial species. During this time, Indigenous people initiated sustained fire management practices that created habitat mosaics still reflected in the contemporary landscape. In the Late Holocene, people also developed resource harvesting strategies for California mussels and forage fishes geared towards long-term productivity.

Archaeologists working in the Late Formative Lake Titicaca Basin have identified several "transit communities"—villages that benefited from long-distance exchange. Some scholars suggest that such places played a key role in the development of the Middle Horizon city of Tiwanaku. In this article, we explore the movement of plant goods into transit communities during both the Late Formative (300 BC–AD 500) and Middle Horizon (AD 600–1100) periods. After presenting the current understanding of transit communities, we summarize previous work on both local plants, including tubers and quinoa, and the presence of maize. We then report on a recent microbotanical study of ceramics recovered from excavations at Late Formative Challapata (in the eastern basin) and a burial from the Middle Horizon occupation at Chiripa (in the southern basin). For the first time we identify lowland tubers in the Lake Titicaca Basin, including yuca, sweet potato, and arrowroot. These findings reveal the critical importance of microbotanical analyses for tracing regional connections and foodways in emergent Middle Horizon worlds, as well as the need for more complex interpretive models for things/plants-in-motion.

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.

In Spring 2018, Natasha A. Fernández-Pérez approached Christine A. Hastorf because she wanted to do a Directed Reading on phytolith and starch applications to archaeology. Since she wanted to work on the Historical/Contemporary Caribbean, where there plantscape has been affected by colonialism, imperialism and globalization, the readings ranged from all over the Neotropics and included few relevant plants from the Old World (e.g. rice, bananas and Near Eastern cereals).

Recent research at Jaketown, a Late Archaic earthwork site in the Lower Mississippi Valley, suggests that the culture-historical framework used to interpret Jaketown and contemporary sites in the region obscures differences in practices across sites. As an alternative, we propose a framework focused on variation in material culture, architecture, and foodways between Jaketown and Poverty Point, the regional type site. Our analysis indicates that people used Poverty Point Objects and imported lithics at Jaketown by 4525-4100 cal BP--earlier than elsewhere in the region. By 3450-3350 cal BP, people intensively occupied Jaketown, harvesting a consistent suite of wild plants. Between 3445 and 3270 cal BP, prior to the apex of earthwork construction at Poverty Point, the community at Jaketown built at least two earthworks and multiple post structures before catastrophic flooding sometime after 3300 cal BP buried the Late Archaic landscape under alluvium. These new data lead us to conclude that the archaeological record of the Late Archaic Lower Mississippi Valley does not reflect a uniform regional culture. Rather, relationships between Jaketown and Poverty Point indicate a multipolar history in which communities selectively participated in larger social phenomena--such as exchange networks and architectural traditions--while maintaining diverse, localized practices.

During the seventeenth century, Spanish colonists began settling in New Mexico. As an agrarian society, the successful establishment of the colony rested on the colonists' ability to create relationships with plants and animals in the colony's novel environmental conditions. Using zooarchaeological and paleoethnobotanical evidence from the capital of Santa Fe and several seventeenth-century ranches, this paper explores the connections colonists had with plants and animals in this new region. The faunal remains among the sites are remarkably consistent: a mix of domesticated mammals, birds, and fish, with few endemic mammals. Plant foods included local and introduced crops and gathered plants, generally available around the ranches. For building materials and fuel, colonists engaged common land farther afield. The data indicate that a broad spectrum of activities were centered on the farm, but common areas provided critical resources. [ABSTRACT FROM AUTHOR]

This study investigates the temporal and spatial factors driving the domestication of Capsicum annuum var. annuum L. in Mexico. This species exhibits the greatest morphological diversity in fruit among Capsicum species-a characteristic that is even more pronounced in contemporary landraces cultivated by indigenous communities. Despite the chili pepper's integral role in regional culinary traditions, its domestication history in this region remains poorly understood, often subject to scholarly interpretations that marginalize or oversimplify archaeological evidence. To address this gap, our interdisciplinary team of archaeologists, botanists, and ecologists combine modern and archaeological Capsicum seed data, diachronic archaeological site locations, and ecological niche modeling to identify potential regions where early human populations and the closest wild ancestors may have coexisted. Our results show spatial correlations between early Capsicum distribution and archaeological site prevalence, suggesting that the beginning of the domestication process occurred in ecologically suitable areas for both wild Capsicum and human settlement. These findings challenge previous hypotheses regarding highland/dry cave domestication regions, as our data indicate that lowland regions-specifically the Yucatán Peninsula and southern coastal Guerrero-were more conducive to early encounters between wild Capsicum and humans. We propose a geographically diffuse and protracted model of chili pepper domestication-driven by a ruderal pathway-which involved at least two asynchronous events across Mexico., Competing Interests: Competing interests statement:The authors declare no competing interest.

Despite decades of investigation, consensus has yet to be reached on when and where wheat replaced millet as the primary crop in the core regions of early Imperial China. Previous studies have suggested that wheat cultivation likely became widespread prior to or during the Han Dynasty (202 BC–AD 220). Here, we tested this hypothesis by applying archeobotanical tools to plant remains found in five pottery model granaries (cang) entombed in a newly excavated late Western Han burial at the Longzaocun cemetery in the Guanzhong Basin. This analysis allowed us to explore the extent of wheat expansion and agricultural strategies in the heartland of early dynastic China. Macro- and micro-botanical evidence shows that the Longzaocun residents consumed two kinds of crops: foxtail and common millet. Combining these findings with previous studies, we argue that millet-based multi-crop farming dominated the regional agricultural system during the Western Han Dynasty (202 BC-AD 8) and analyze the political and cultural motivations for the Han people's usage on millet crops from the burial concepts and fiscal systems. Echoing previous studies, we argue that millets remained the most valuable subsistence food for inhabitants of the Loess Basins in the Han core, and that wheat was not cultivated on a large scale in this area during the Western Han Dynasty.

Peoples living in the Eastern Woodlands of North America domesticated a suite of small‐seeded crops between five thousand and two thousand years ago, making this region one of roughly ten independent centers of domestication across the globe. In the Southern Appalachian region, foraging peoples began cultivating these native crops around thirty‐five hundred years ago (during the Late Archaic period [3000–800 BCE]); by the start of the Early Woodland period (800–200 BCE), they had significantly altered their lifeways and surrounding landscape. This included a change in the physical landscape, as demonstrated by paleoethnobotanical data, with an increase in weedy plants at the expense of bottomland forests. Groups also significantly shifted their lifeways, becoming more sedentary, as evidenced by an increase in storage pits, more substantial structures, and the adoption of ceramic vessels. Storage pits also tend to be smaller, indicating a shift from community‐based food procurement and storage to the household level. This may reflect the development of private property and distinctions among households with differential access. Community‐based rituals, as evidenced in several caves and rock‐shelters in the region, may have been established to strengthen group ties in the face of the broader changing social and physical landscape.

Palaeoecological and archaeological studies often use soil phytoliths to gain insight into past vegetation changes and the long-term use of plants by people, particularly domesticated cultivars. However, to make accurate interpretations and analyses using plant phytoliths, regionally-specific reference collections are warranted. There is ample research documenting phytolith morphotypes observed in grass species worldwide (due to their high phytolith production), and of dicots in tropical regions, but there is dearth of phytolith references for dicot species in temperate regions like the Pacific Northwest of North America. This study aims to fill part of this gap by documenting phytolith morphotypes observed in 60 culturally important plant foods, medicines, and textiles, all predominantly dicot species. Phytoliths are classified by abundance in specific plant parts (e.g., stem, leaf, flower) and the findings are compared to closely related species studied elsewhere. Results indicate that many of the dicot plant species in the Pacific Northwest produce more phytoliths than closely related species worldwide, likely due to differing environmental factors which affect phytolith production in plants. These findings could be useful in palaeoecological contexts to assess vegetation changes or identify dicot-dominated ecosystems, like Indigenous cultivated and managed forests and other perennial fruit tree/shrub dominated landscapes. Additionally, three of the species studied here showed possible diagnostic phytoliths but further confirmation is warranted. Future studies should consider localized environmental patterns affecting phytolith production, and therefore, our understanding of phytolith taxonomy and deposition/taphonomy. • Dicot plant species in the Pacific Northwest of North America are understudied in phytolith research. • 60 culturally important plant species were examined for phytoliths in different tissues. • Most samples were more silicified than reported on in previous studies. • Environmental factors likely cause differences in silicification of plant species.

Paleoethnobotanical perspectives are essential for understanding past lifeways yet continue to be underrepresented in Paleoindian research. We present new archaeobotanical and radiocarbon data from combustion features within stratified cultural components at Connley Caves, Oregon, that reaffirm the inclusion of plants in the diet of Paleoindian groups. Botanical remains from three features in Connley Cave 5 show that people foraged for diverse dryland taxa and a narrow range of wetland plants during the summer and fall months. These data add new taxa to the known Pleistocene food economy and support the idea that groups equipped with Western Stemmed Tradition toolkits had broad, flexible diets. When viewed continentally, this work contributes to a growing body of research indicating that regionally adapted subsistence strategies were in place by at least the Younger Dryas and that some foragers in the Far West may have incorporated a wider range of plants including small seeds, leafy greens, fruits, cacti, and geophytes into their diet earlier than did Paleoindian groups elsewhere in North America. The increasing appearance of diverse and seemingly low-ranked resources in the emerging Paleoindian plant-food economy suggests the need to explore a variety of nutritional variables to explain certain aspects of early foraging behavior.

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.

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.

The ethnohistorical, ethnographic, and contemporary literatures all suggest that common bean (Phaseolus vulgaris) was an important component of Northern Iroquoian agronomic systems and diets. Seemingly at odds with this is the sparse occurrence of whole and partial common bean seeds on fourteenth through seventeenth century AD village sites. The recovery of a large quantity of whole and partial bean seeds from the ancestral Oneida Diable site, dated here to between AD 1583 and 1626 with a Bayesian model using seven new AMS radiocarbon dates, provides clues as to when large quantities of rehydrated/cooked common bean seeds may occur in the archaeological record.

Investigations at sites across northwestern Honduras—inside and outside the Maya area—have revealed diverse food activities and ingredients. Paralleling the evidence from durable artifact assemblages, we see transformation over time in materials and practices, as well as the movement of elements across the landscape. Botanical evidence points toward a dynamic overlap between northern and southern societies, with northwestern Honduras serving as a sort of regional crossroads. In this article, we compare cuisines from several ancient communities in northwestern Honduras, using microbotanical and macrobotanical residues. We briefly address the political and historic context of the region and provide abridged biographies of several culinary taxa. Of particular interest are milpa annual crops such as maize and squash, managed and cultivated palm species, wild and managed herbaceous species, edible fruit species, and root and tuberous crops such as lerén, sweet potato, and manioc.

Plants and foodways have long been recognized for their importance to the construction of identity and culture in plantation settings. Yet despite this focus on plants and foodways in plantation archaeology, there is a need for more archaeological documentation of the types of plants and fields being cultivated in newly formed plantations in the New World. We combine historical documentation with an assemblage of recovered plant remains from the Lord Ashley site (38DR83a) to examine plant use during the formative years of a plantation economy. A renewed focus on experimental cropping in the New World plantation system at this site, along with one of the most well documented enslaved African populations before the 1690s in South Carolina, point to the influence of cross-cultural entanglements in building New World agricultural systems. The recovery of watermelon, an African cultivar, found alongside an assemblage of artifacts and other archaeobotanical remains associated with the enslaved Africans at the site, also point to the role of first-generation Africans in establishing New World foodway traditions.
