The abundance, distribution, and size of marine species are linked to temperature nutrient regimes profoundly affected by humans through exploitation climate change. Yet little is known about long-term historical links between ocean environmental changes resource abundance provide context for current potential future trends inform conservation management. We synthesize >4000 years ecosystem dynamics in a Northwest Atlantic region currently undergoing rapid changes, the Gulf Maine Scotian...
Stable oxygen isotopes from estuarine bivalve carbonate Saxidomus gigantea were analysed combined with high‐resolution sclerochronology modern and archaeological shells British Columbia, Canada, to determine the seasonality of shellfish collection site Namu. The combination a micro‐milled sampling strategy for δ 18 O analysis permits precise estimate seasonality, because seasonal freshwater influxes changes in temperature have dual effects on value shell. Sclerochronological identifies...
Horizon scanning is an increasingly common strategy to identify key research needs and frame future agendas in science. Here, we present the results of first such exercise for field sclerochronology, thereby providing overview persistent emergent questions that should be addressed by studies. Through online correspondence following 5th International Sclerochronology Conference 2019, participants submitted rated either knowledge gaps or promising applications sclerochronology. An initial list...
ABSTRACT Biogeochemical and growth increment analyses show contrasting seasonal patterns of butter clam collection rates harvest intensity between archaeological shell midden sites from the Dundas Islands archipelago mainland coast in Prince Rupert Harbour, northern British Columbia. Growth analysis shows more intensive comparison to residential Harbour. Stable oxygen isotope multi-seasonal clams a seasonally specific emphasis Comparison these results those similar studies Namu region on...
Shells of intertidal bivalve mollusks contain sub-seasonally to interannually resolved records temperature and salinity variations in coastal settings. Such data are essential understand changing land-sea interactions through time, specifically atmospheric (precipitation rate, glacial meltwater, river discharge) oceanographic circulation patterns; however, independent proxies currently not available. We established a model for reconstructing daily water temperatures with an average standard...
The Sechelt inlet system (SIS), situated on the inner Sunshine Coast of British Columbia, lies within territory shíshálh Nation. This study focuses ∼1000 years shellfish harvesting from 930-0 cal. BP. Specifically, we investigated seasonal timing collection, relative pressure and paleo-temperature reconstruction at four archaeological sites. Thirty butter clam shells (Saxidomus gigantea) SIS underwent high-resolution shell oxygen isotope (δ18O) analysis 662 individual fragments were analysed...
ABSTRACT In 1982, Chisholm et al. used δ 13 C data for human burials from shell midden sites widely distributed on the coast of British Columbia (BC) to show extreme dependence these individuals high trophic level marine consumers, principally salmon and mammals. Here, we present previously unpublished analyses 15 N some same as well additional individuals. Nitrogen isotope that diet was dominated by fauna including carnivorous fish Although most were found in middens, mollusks made up only...

Five seasons of survey and excavation in Port Joli Harbour, NS, Canada, have resulted a high-resolution archaeofaunal sample from 2 contrasting shell-bearing sites: AlDf-24, AlDf-30 (Jack's Brook). In this paper, we discuss the evidence for differences mollusk-, fish-, mammal-harvesting strategies between contemporaneously occupied sites. Furthermore, highlight shifts Mi'kmaw exploitation coastal resources around Middle to Late Maritime Woodland transition (ca. 1300 cal B.P.). Finally,...
Stable‐isotope ratios of two modern Saxidomus gigantea specimens from Namu, British Columbia, are presented to show intraspecimen and interspecimen isotopic variation. Isotopic profiles ( δ 13 C shell , 18 O ) were generated along the axis maximum growth. The that analogous seasonal variation is recorded in ; however, significant variability . We suggest this caused by differences metabolic activity between individuals. Intrashell a growth horizon shows good reproducibility but especially at...
ABSTRACT Fewer than 200 radiocarbon ( 14 C) dates with secure contextual information are available for Cuba, making it challenging to reconstruct Caribbean indigenous population dynamics, their identities and interactions. In this paper, we discussed 21 accelerator mass spectrometry (AMS) C from two mounds (M1 M2) at the Playa del Mango site (Granma province, Cuba), traditionally associated Banwaroid stone tool tradition. The ΔR calculated was –132.0 ± 176 –164.0 68. chronology of burials...
Powdered biogenic calcium carbonate from butter clams shows variations in its tendency to convert aragonite calcite when suspended water, depending on whether the suspension has additional or not. Our investigations treat these samples as complex hierarchical materials, considering both their mineral and organic components. We assess composition Attenuated Total Reflection Fourier Transform Infrared spectroscopy peak shifts, well quantitative assessments of lattice constant refinements...
