Tracking local radiocarbon releases from nuclear power plants in southern Ontario (Canada) using annually-dated tree-ring records
Open AccessFelix Vogel, Carley Crann et al.ARTICLEAnthropocene2022Referências: 37
Understanding the radiocarbon (14C) content of atmospheric carbon dioxide (CO2) underlies many fields of research. This study shows how one can track the influence of nuclear power plants at the local and regional scale in Canada's largest urban area. This area is subject to significant 14CO2 depletion due to CO2 emissions from fossil fuel burning. Tree cores collected across southern Ontario in 2018 show that tree-rings dated annually record the…
Forest vegetation change and disturbance interactions over the past 7500 years at Sasquatch Lake, Columbia Mountains, western Canada

Paleoclimatology
Open AccessMichael Fj Pisaric, Michael F J PisaricCHAPTERInternational Encyclopedia of…2017
The Earth's climate has constantly evolved and changed throughout its 4.8 billion‐year history. During most of the Earth's history, climate has been characterized as hyperthermal, punctuated by cool periods during the Neoproterozoic, late Ordovician, early Permian, late Jurassic, and from the early Eocene to the present. These broad changes in climate occurred in response to a number of internal and external‐forcing mechanisms, including changes …
Determinants of fire activity during the last 3500 yr at a wildland—urban interface, Alberta, Canada
Open AccessEmma Lou Davis, C J Courtney Mustaphi et al.ARTICLEQuaternary Research2016
Long-term records of wildfires and their controlling factors are important sources of information for informing land management practices. Here, dendrochronology and lake sediment analyses are used to develop a 3500-yr fire and vegetation history for a montane forest in Jasper National Park, Alberta, Canada. The tree-ring record (AD 1771-2012) indicates that this region historically experienced a mixed-severity fire regime, and that effective fir…

Paleoecological and Sedimentological Data from
Open AccessC J Courtney Mustaphi, Ze’ev Gedalof et al.ARTICLEOpen Quaternary2015Referências: 8
This dataset contains sedimentological and paleoenvironmental measurements from a 351.5 cm sediment core that was collected from Pyatts Lake, south-east British Columbia, Canada. Sedimentological data include: radiocarbon dates and age-depth model, magnetic susceptibility, loss-on-ignition values, and particle size distributions. Palaeoecological data include: macroscopic charcoal (>150 μm), charcoal morphotypes; aquatic macroremains; pollen spec…
Holocene climate–fire–vegetation interactions at a subalpine watershed in southeastern British Columbia, Canada
Open AccessC J Courtney Mustaphi, Michael Fj Pisaric et al.ARTICLEQuaternary Research2014
Vegetation assemblages and associated disturbance regimes are spatially heterogeneous in mountain ecosystems throughout the world due to the complex terrain and strong environmental gradients. Given this complexity, numerous sites describing postglacial vegetation and fire histories are needed to adequately understand forest development and ecosystem responses to varying climate and disturbance regimes. To gain insight into long-term historical c…
A ring-width-based reconstruction of June–July minimum temperatures since AD 1245 from white spruce stands in the Mackenzie Delta region, northwestern Canada
Open AccessTrevor J Porter, Michael Fj Pisaric et al.ARTICLEQuaternary Research2013
We present a reconstruction of June–July minimum temperatures since AD 1245 for the Mackenzie Delta region based on a 29-site network of white spruce ( Picea glauca ) ring-width series. Most but not all trees experienced a divergent temperature–growth response, similar to the divergence that has affected other white spruce trees across Yukon and Alaska. However, divergence in the study region began as early as AD 1900 and we have documented our m…
Using Multiple Sources of Knowledge to Investigate Northern Environmental Change
Open AccessSteve V Kokelj, T C Lantz et al.ARTICLEARCTIC2012
Field data, remote sensing, and Inuvialuit knowledge were synthesized to document regional ecological change in the outer Mackenzie Delta and to explore the timing, causes, and implications of this phenomenon. In September 1999, a large magnitude storm surge inundated low-lying areas of the outer Mackenzie Delta. The storm was among the most intense on record and resulted in the highest water levels ever measured at the delta front. Synthesis of …

Holocene treeline dynamics in the mountains of northeastern British Columbia, Canada, inferred from fossil pollen and stomata
Open AccessMichael Fj Pisaric, Michael F J Pisaric et al.ARTICLEThe Holocene2003Citada por: 1Referências: 6
Changes in pollen and stomata assemblages in sediment cores recovered from tundra and foresttundra lakes in alpine regions of northeastern British Columbia reflect vegetation and inferred climatic change throughout the Holocene. Pollen and stomata records are presented from two lakes, BC2 located in the alpinetundra zone and Dead Spruce Lake at the present elevation of subalpine treeline. The pollen and stomata records from BC2 indicate that an e…
