Coles Creek fauna procurement strategies: subsistence diversity among late prehistoric hunter-gatherer-horticulturalists in the Lower Mississippi Valley

In the late 1980s, a collaborative effort between Harvard University’s Lower Mississippi Survey and Tulane University’s Center for Archaeology launched a study examining the causes and consequences of subsistence change in the Lower Mississippi Valley. The Osceola Project contributed the first formal study of late prehistoric faunal remains within the Alluvial Plain, becoming the standard against which all subsequent Coles Creek faunal assemblages have been measured. Recent evidence recovered from three sites located in the Eastern Uplands presented the opportunity to compare and contrast vertebrate subsistence in these two distinct physiographic regions. We hypothesize that a clear distinction exists between lowland and upland Coles Creek procurement strategies. This article evaluates this claim by examining species diversity, spatial patterns, and temporal trends evident within an eight-site sample. The results suggest that the primary factor influencing Coles Creek fauna procurement was the immediate environment, and that the composition of Late Woodland period diets may be a reflection of efficiency of effort rather than food access or scarcity.     

Early Construction of a Maya Sacred Landscape: The Sector Y “E-Group” of Nixtun-Ch’ich’ (Petén,Guatemala)

The southern lowland Maya city of Nixtun-Ch’ich’ exhibits an atypical gridded layout imposed in the Middle Preclassic period (800–400 b.c.). Sector Y, in the monumental core, consists of a two-part sub-structural platform with an “E-Group” quasi-astronomical architectural complex (Platform Y1) and a deep natural depression or fosa, Fosa Y (Platform Y2). Earliest construction began with bedrock leveling, probably around 1100–1000 b.c., followed by late Terminal Early Preclassic and transitional Terminal Early to early Middle Preclassic building, subsequent massive Middle Preclassic rebuilding, and Late Preclassic enlargement. Excavations in Sector Y provide evidence of the early phases of construction of a sacred landscape proposed to have been based on a mythical creation-crocodile’s back. More broadly, this work contributes to studies of early societal complexity and urbanization in the Maya lowlands, in Mesoamerica, and beyond.     

The Evolution of Peat‐Swamp Channels and Organic Floodplains,Barrington Tops,New South Wales,Australia

Geomorphology, geochronology and palynology are used to assess the development and stability of two channelled swamps on the Barrington Tops plateau. While both swamps commenced peat accumulation prior to about 4000 cal BP, new stratigraphic data indicate incision between 700 and 1000 cal BP, in response to regional climate change. Two broad stratigraphic units are identified in each swamp: the upper floodplain, comprised entirely of peat, and the inset floodplain, underlain by interbedded peat and fluvial sediments. Following incision, rapid vertical growth of the inset floodplain occurred on the Barrington River between 690 and 620 cal BP, and palynological data indicate a change from more saturated pre‐incision swamp flora to less saturated post‐incision swamp flora. Bankfull stage‐height, achieved many times in a year, is remarkably consistent along the length of each swamp channel. Its elevation controls the overall elevation of the swamps by controlling the height of the water‐table and hence the growth of swamp vegetation and formation of peat. In particular, contemporary channel dimensions control the growth and height of the inset floodplain, a process that results in the formation of an organic floodplain not previously described in the geomorphic literature.     

Historical ecology coming of age

Historical ecology is a research program that in earnest has emerged within anthropology since the turn of the millennium. This essay offers a short outline of historical ecology and, on the basis of a review of four volumes published over the last decade, discusses several key issues in the historical ecological analyses of socio-environmental relations. It is argued that historical ecology (1) emerged as a concept in different, but related, discursive contexts, (2) coalesced in North American anthropology and anthropological archaeology, and (3) subsequently cross-fertilized and diversified in new academic milieus successfully addressing previously unconsidered research questions in novel ways.     

An Examination of Vertical Accretion of Floodplain Sediments in the Labasa River Sugarcane Belt of Northern Fiji: Rates,Influences and Contributing Processes

The ¹³⁷Cs (caesium‐137) method was used to investigate medium‐term rates of sediment deposition on the floodplain of the Labasa River, on Vanua Levu island in northern Fiji. The Labasa basin is commercially important for sugarcane farming, which provides much revenue and sustains the economy in the greater Labasa area. Alluvium was sampled at three riverbank sites in vertical increments of 30 mm. Measured net vertical accretion rates, based on analysis of depth‐profiles of ¹³⁷Cs activity, ranged from 10 mm yr^?1 at a low‐lying site near a tributary confluence with the main river, to 60 mm yr^?1 on a levée that was elevated slightly above the adjacent floodplain. These rates of accretion are high, but in general agreement with rates recorded using similar methods in other tropical Pacific island river systems. Soil erosion under sugarcane on hilly parts of the lower Labasa basin is an important factor in rapid floodplain development. Observations made during Cyclone Ami, which traversed Vanua Levu island in early 2003, illustrate the major contribution of severe storm events to floodplain sediment supply, by triggering numerous landslides on catchment slopes and in‐channel debris floods, and by generating large‐magnitude overbank floods.     

Lowland Floodplain Responses to Extreme Flood Events: Long-Term Studies and Short-Term Microbial Community Response to Water Environment Impacts

Abstract

Targeted studies of waterlogged burial environments allow researchers to gain holistic insights into the physico-chemical and biological condition of wetlands that have the potential to contain organic remains of both anthropogenic and biogenic origin. Recent research has shown that microbial community diversity and functioning are intimately linked to physical and chemical parameters, such that environmental perturbations may have the potential to enhance the effectiveness of microbial communities in the degradation process. Our studies have shown that, as a consequence of the 2007 floods which impacted upon many British lowland rivers, a rapid microbial response to environmental perturbations can be demonstrated within the wetland deposits being monitored. As such, a quantification of the latent functionality of micro-organisms in a soil profile may be of fundamental importance for our understanding of potential in situ degradation processes; and, as a consequence, the likelihood for the biodegradation of sensitive archaeo-organic remains; a factor which is of primary importance for both ongoing and future mitigation strategies, and attempts at managing the cultural resource of wetlands.

This paper will present a consideration of the effectiveness of a long-term research project in a lowland wetland at Newington, Nottinghamshire, England, studied between 2004 and 2008; and evaluate the efficacy of this study in relation to the significant impacts that occurred as a result of the severe floods in 2007. We conclude that the data generated after the floods necessitated a total re-evaluation of the first approximately two years of environmental monitoring, and that the impacts throughout the sediment profile continued for some time after the initial flood event. These observations potentially have far-reaching implications for future in situ monitoring as disruptions to weather patterns influence the various environmental impacts on the wetland resource.     

Late Classic Maya Pottery Production: Review and Synthesis

Studies of the organization of Maya pottery production have been pursued via numerous methods but without theoretical models. I review available data on production of Late Classic southern lowland Maya polychrome pottery in light of my calendrically based may model of geopolitical organization. I conclude that: (1) production arrangements vary by “kind” of pottery; (2) “craft specialization” and “workshops” are inappropriate concepts; (3) study of polychrome production necessitates multiple approaches, including analysis of decorative content; (4) better “bridging arguments” and “middle-range theory” are needed; (5) figural polychromes were “inalienable” wealth goods; and (6) they were painted in palaces of primary and secondary centers—may and k'atun seats in the model—in realm-specific signature styles.
