Abstract Oysters inhabit a variety of coastal and deep‐sea settings over wide latitudinal range have role as ecosystem engineers. They also represent an important food source for humans since hunter‐gatherer times, which motivates interest in using oyster shells environmental life history archives. Still, oysters often been disregarded sclerochronology studies, although several methods based on both microtextural geochemical approaches successfully investigated. We review how these used to improve interpretations shell records, we identify knowledge gaps disciplines. Those include ecology study larval dispersal growth rates; archaeology determine midden constructions site occupations; palaeoenvironmental palaeoclimate reconstructions from tidal annual timescales. suggest standardizing procedures biophysical models dispersal.

Modeling the potential impact of storm surge and sea level rise on coastal archaeological heritage: A case study from Georgia

PLoS ONE, Год журнала: 2024, Номер 19(2), С. e0297178 - e0297178

Climate change poses great risks to archaeological heritage, especially in coastal regions. Preparing mitigate these challenges requires detailed and accurate assessments of how heritage sites will be impacted by sea level rise (SLR) storm surge, driven increasingly severe storms a warmer climate. However, inconsistency between modeled impacts erosion on observed effects has thus far hindered our ability accurately assess the vulnerability sites. Modeling largely focused medium-to-long term SLR, while observations damage have almost exclusively results individual events. There is therefore need for desk-based modeling potential events equip cultural managers with information they plan surge various future scenarios. Here, we apply Sea, Lake, Overland Surges from Hurricanes (SLOSH) model estimate that pose along coast US State Georgia four different SLR Our results, shared Historic Preservation Division facilitate prioritization, documentation, mitigation efforts, demonstrate over 4200 alone are at risk inundation hurricanes, more than ten times number were previously estimated 2100 accounting alone. We hope this work encourages necessary action toward conserving physical beyond.

The dynamics of fishing villages along the South Atlantic Coast of North America (ca. 5000–3000 years BP)

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Фев. 26, 2024

Abstract We present new chronologies that inform the timing and tempo of shell ring mound construction on South Atlantic Bight. Our project combines recently acquired dates with legacy radiocarbon from over 25 rings mounds to provide a higher-resolution chronology regarding occupation formation this larger landscape earliest fishing villages along East Coast United States. resolve ordering these through Bayesian statistical modeling. These models historicize contextualize in ways previously impossible. Specifically, our indicate were established prior invention pottery. The early period village establishment evidences isolated rings, whereas later periods seem have more villages, but appear been relocated other areas and/or islands time. Shell are fewer number, spread throughout time period, may represent special purpose sites compared shell-rings. Once spread, they quickly adopted technologies (i.e., pottery) created institutions practiced relocation, which allowed way life persist for than thousand years.

Aquaculture in the Ancient World: Ecosystem Engineering, Domesticated Landscapes, and the First Blue Revolution

Journal of Archaeological Research, Год журнала: 2023, Номер 32(3), С. 427 - 491

Опубликована: Сен. 12, 2023

Abstract Aquaculture is the world’s fastest growing food sector and accounts for more than 50% of fish supply. The significant growth in global aquaculture since middle 20th century has been dubbed by Blue Revolution. However, it not first Revolution to take place human history. While historically classified as low-ranking, seasonal, or starvation resources archaeological discourse, marine foods were vital that ancient communities developed exploited using a vast array strategies. Among these aquatic strategies was aquaculture. This initiated during Early Holocene, some 8,000 years ago China, with archaeologists now documenting across globe. review considers commonalities between aquacultural systems including evidence ecosystem engineering development domesticated landscapes production systems. People past constructed agroecosystems only enhance diversify resources, but control reliability key subsistence meet demands ritual practice conspicuous social stratification. These maintained centuries, if millennia. Worldwide research conducted on can provide critical insights into developing ecologically sustainable, resilient, diverse coastal today, thus, achieving industry sustainability limiting negative environmental impacts shorelines overexploited fisheries.

Stable Isotope Analysis and Chronology Building at the Hokfv-Mocvse Cultural Site, the Earliest Evidence for South Atlantic Shell-Ring Villages

American Antiquity, Год журнала: 2024, Номер unknown, С. 1 - 20

Опубликована: Авг. 27, 2024

Abstract Circular shell rings along the South Atlantic coast of United States are vestiges earliest sedentary villages in North America, dating to 4500–3000 BP. However, little is known about when Indigenous communities began constructing these shell-ring villages. This article presents data from Hokfv-Mocvse Shell Ring on Ossabaw Island, Georgia. Although often associated with ceramics no were encountered our excavations at Hokfv-Mocvse, and only materials recovered projectile points similar found over 300 km inland. Bayesian modeling radiocarbon dates indicates that ring was occupied between 5090 4735 cal BP (95% confidence), making it dated region. Additionally, geochemistry oyster paleobiology suggest inhabitants living year-round had established institutions time manage fisheries sustainably. therefore provides evidence for people settling adapting coastal environments region centuries before adoption pottery. The establishment marks a visible archaeological shift toward down occupying island ecosystems more permanent basis larger numbers than ever
