Agriculture significantly reshapes soils and ecology, often with lasting ecological impacts. For over a millennium, the Menominee Indian Tribe of Wisconsin have practiced maize agriculture in upper Great Lakes. Though vast majority ancestral Indigenous agricultural sites been destroyed American Midwest, documented numerous archaeological, raised garden bed at their Reservation, enabling an investigation into vegetation impacts practices. Here, we report findings from our pilot surveys three sites. Results show that all surveyed are high quality ecosystems. We observed differences species richness between non-agricultural places, although varied based on location. Overall, illustrate complexity these anthropogenic, biologically diverse landscapes shaped by past contemporary land use how today’s ecology is part enduring legacy

Since the 21st century, China has shown dramatic rural depopulation and rapid urbanization, surface vegetation been affected by this urban–rural development pattern. Using remote sensing population data from 2000 to 2020, we investigated spatial temporal evolution of terrestrial under coexistence “rural loss urbanization”. We also analyzed relationship between loss, urbanization area covered four types (forest, grassland, shrubs cropland). found that forests is increasing, shrubs, grasslands, cropland decreasing. Spatially, results Moran index prove characterized autocorrelation. Grasslands are predominantly located on western side Hu line, forests, croplands eastern line. Rural contributes growth forest grassland cover, but inhibits shrub cover. The advance reduces benefits As a result direct effect, reduction cropland, while promotes opposite true for spillover effect. This study helps us better understand direction ecological shifts in migration patterns.

Abstract. Here we describe the LegacyPollen 1.0, a dataset of 2831 fossil pollen records with metadata, harmonized taxonomy, and standardized chronologies.

Ethnographic evidence documents the exploitation of Gambel oak ( Quercus gambelii) acorns as a food resource in Great Basin, Southwest, and Colorado Plateau. However, paucity identified macro- micro-botanical acorn remains archaeological record has resulted critical underestimation significance for Indigenous groups these regions. This paper reports data from 18 hours experimental foraging direct bomb calorimetry to evaluate whether would have been profitable Holocene foragers incipient maize agriculturalists. Results show that return substantial amount calories at 5,711.12 kcal per hour were likely significant early- middle hunter-gatherers an important fallback late-Holocene agriculturalists region.

Abstract Geophytes are hardy, resilient plants that tolerant of cold temperatures and drought well documented as a reliable food source for hunter-gatherers worldwide. Human settlement patterns foraging behaviors have long been associated with the use nutrient-dense geophytes rich in carbohydrates, fiber, vitamins, minerals. Indigenous communities northern Great Basin developed cultural practices centered around gathering, preparing, consuming important geophytic plants. These became deeply embedded their identity, forming rituals, stories, traditions persist today. Although there is strong ethnographic precedent significance geophytes, finding evidence archaeological record remains challenge. This study analyzed starch residue extracted from bedrock metates uplands Warner Valley, Oregon. Systematic studies granules collected extant plant growing near sites were applied to identification granules. Starch specifically Lomatium spp. (biscuitroot), identified on metate surfaces at all sites, thus providing direct collection processing geophyte vegetables. Evidence contributes theories about subsistence strategies, food-processing technologies, social organization, past human societies.
