Highland forest dynamics across equatorial East Africa during the end of the African humid period
The Swan Point Site, Alaska
The Swan Point site in interior Alaska contains a significant multi-component archaeological record dating back to 14,200 cal BP. The site’s radiocarbon ( 14 C) chronology has been presented in scattered publications that mostly focus on specific archaeological periods in Alaska, in particular its terminal Pleistocene components associated with the East Beringian tradition. This paper synthesizes the site’s 14 C data and provides sequential Bayes…
Advances in global bioavailable strontium isoscapes
Early human dispersals within the Americas
Complex processes in the settling of the Americas The expansion into the Americas by the ancestors of present day Native Americans has been difficult to tease apart from analyses of present day populations. To understand how humans diverged and spread across North and South America, Moreno-Mayar et al. sequenced 15 ancient human genomes from Alaska to Patagonia. Analysis of the oldest genomes suggests that there was an early split within Beringia…
Strontium and Oxygen Isotope Profiles of Sequentially Sampled Modern Bison ( Bison bison bison ) Teeth from Interior Alaska as Proxies of Seasonal Mobility
Studies addressing prehistoric mobility in animals typically use isotopic analyses of sequentially formed tissues, such as the growth layers in teeth, to infer physical movement on the landscape. Strontium isotope ratios (87Sr/86Sr values), which vary geographically, are particularly useful for this purpose, especially when paired with stable oxygen isotope ratios (δ18O), which vary seasonally. Together, these two isotope systems can provide info…
A 5500-year oxygen isotope record of high arctic environmental change from southern Spitsbergen
The oxygen isotope composition of chironomid head capsules in a sediment core spanning the past 5500 years from Lake Svartvatnet in southern Spitsbergen was used to reconstruct the oxygen isotope composition of lake water (δ 18 O lw ) and local precipitation. The δ 18 O lw values display shifts from the baseline variability consistent with the timing of recognized historical climatic episodes, such as the Roman Warm Period, the Dark Ages Cold Per…
High-resolution records detect human-caused changes to the boreal forest wildfire regime in interior Alaska
Stand-replacing wildfires are a keystone disturbance in the boreal forest, and they are becoming more common as the climate warms. Paleo-fire archives from the wildland–urban interface can quantify the prehistoric fire regime and assess how both human land-use and climate change impact ecosystem dynamics. Here, we use a combination of a sedimentary charcoal record preserved in varved lake sediments (annually layered) and fire scars in living tree…
Methane turnover and environmental change from Holocene lipid biomarker records in a thermokarst lake in Arctic Alaska
Arctic lakes and wetlands contribute a substantial amount of methane to the contemporary atmosphere, yet profound knowledge gaps remain regarding the intensity and climatic control of past methane emissions from this source. In this study, we reconstruct methane turnover and environmental conditions, including estimates of mean annual and summer temperature, from a thermokarst lake (Lake Qalluuraq) on the Arctic Coastal Plain of northern Alaska f…
Late Pleistocene paleoecology of arctic ground squirrel ( Urocitellus parryii ) caches and nests from Interior Alaska's mammoth steppe ecosystem, USA
Botanical analyses of fossil and modern arctic ground squirrel ( Urocitellus parryii ) caches and nests have been used to reconstruct the past vegetation from some parts of Beringia, but such archives are understudied in Alaska. Five modern and four fossil samples from arctic ground squirrel caches and nests provide information on late Pleistocene vegetation in Eastern Beringia. Modern arctic ground squirrel caches from Alaska's arctic tundra wer…
Paleoecology of mangroves along the Sibun River, Belize
This study examines a sediment core (SR-63) from a mangrove ecosystem along the Sibun River in Belize, which is subject to both changes in sea-level and in the characteristics of the river's drainage basin. Radiocarbon dates from the core show a decreased sedimentation rate from ~ 6 ka to 1 cal ka BP and a marked change in lithology from primarily mangrove peat to fluvial-derived material at ~ 2.5 cal ka BP. Changes in the sedimentation rates obs…
Changes in northeast Pacific marine ecosystems over the last 4500 years
Changes in food web dynamics and ocean productivity over the past 4500 years are investigated using stable isotope analysis of nitrogen and carbon in collagen from animal bones preserved in coastal archeological middens on Sanak Island, along the eastern edge of the Aleutian archipelgo. Samples included Steller sea lions, Harbor seals, Northern fur seals, sea otters, Pacific cod and sockeye salmon. Sea otters had the highest δ 13 C (−11.9 ± 0.7‰)…
Late Quaternary vegetation reconstruction from the Eastern Arc Mountains, Tanzania
Pollen, spore, macrofossil and stable isotope (C and N) analyses from a 266-cm sediment core collected from a swamp on the Eastern Arc Mountains, Tanzania, are used to reconstruct vegetation and environmental history. An estimated time scale based on five 14 C ages records approximately 38,000 yr. This palaeorecord is the first from this biodiversity hotspot and importantly extends through the last glacial maximum (LGM). The altitudinal transitio…
Phytolith indices as proxies of grass subfamilies on East African tropical mountains
A multiproxy peat record of Holocene mangrove palaeoecology from Twin Cays, Belize
The extent and function of coastal mangrove ecosystems are likely to be influenced by future changes in sea level. Multiple proxies of past mangrove ecosystems preserved in a 780 cm long peat core (TCC2) taken from Twin Cays, Belize, record palaeoecological changes since ~8000 cal. yr BP. The proxies included pollen and the stable-isotope (C, N and O) compositions of mangrove leaf fragments. Rhizophora mangle (red mangrove) has been dominant at t…
A multi-proxy lacustrine record of Holocene climate change on northeastern Baffin Island, Arctic Canada
Reconstructions of past environmental changes are critical for understanding the natural variability of Earth's climate system and for providing a context for present and future global change. Radiocarbon-dated lake sediments from Lake CF3, northeastern Baffin Island, Arctic Canada, are used to reconstruct past environmental conditions over the last 11,200 years. Numerous proxies, including chironomid-inferred July air temperatures, diatom-inferr…
Fossil grass cuticles from lacustrine sediments
The need for alternatives to fossil pollen for the reconstruction of vegetation dominated by grasses has prompted the use of grass cuticles, which lack a described method of analysis. Methods used to analyse sediments for palaeoecological materials allied to grass cuticles, including microscopic charcoal, phytoliths and plant cuticles, are reviewed. A simple set of methods and protocols for extracting, identifying and quantifying fossil grass cut…
