  • A 7600 yr vegetation and fire history from Anthony Lake, northeastern Oregon, USA, with linkages to modern synoptic climate patterns

    Open AccessColin J Long, Jaqueline J Shinker et al.ARTICLEQuaternary Research2019

    We used pollen and high-resolution charcoal analysis of lake sediment to reconstruct a 7600 yr vegetation and fire history from Anthony Lake, located in the Blue Mountains of northeastern Oregon. From 7300 to 6300 cal yr BP, the forest was composed primarily of Populus , and fire was common, indicating warm, dry conditions. From 6300 to 3000 cal yr BP, Populus declined as Pinus and Picea increased in abundance and fire became less frequent, sugge…

    We discuss two shared elements in the temporal perspective of human and physical geography—chronology and narration. An example of the use of these elements is in practice provided by repeat photography, a technique used in both subdisciplines, but these elements also are deployed in the development of the theories that shape the fields. We argue that their role in enhancing the “telling of temporal and spatial stories” can contribute to the reso…

  • Development and Disintegration of Maya Political Systems in Response to Climate Change

    Open AccessD J Kennett, Sebastian F M Breitenbach et al.ARTICLEScience2012

    Maya and Climate Climate has affected the vitality of many different societies in the past, as shown by numerous records across the globe and throughout human history. One of the most obvious and spectacular examples of this is from the Classic Maya civilization, whose advanced culture left highly detailed records of all aspects of their existence between 300 and 1000 C.E. Kennett et al. (p. 788 ; see the cover) present a detailed climate record …

  • Long-term perspective on wildfires in the western USA

    Open AccessJennifer R Marlon, Patrick J Bartlein et al.ARTICLEProceedings of the National…2012

    Understanding the causes and consequences of wildfires in forests of the western United States requires integrated information about fire, climate changes, and human activity on multiple temporal scales. We use sedimentary charcoal accumulation rates to construct long-term variations in fire during the past 3,000 y in the American West and compare this record to independent fire-history data from historical records and fire scars. There has been …

  • Climatic control of the biomass-burning decline in the Americas after ad 1500

    Open AccessMJ Power, FE Mayle et al.ARTICLEThe Holocene2012Cited by: 9References: 14

    The significance and cause of the decline in biomass burning across the Americas after ad 1500 is a topic of considerable debate. We synthesized charcoal records (a proxy for biomass burning) from the Americas and from the remainder of the globe over the past 2000 years, and compared these with paleoclimatic records and population reconstructions. A distinct post-ad 1500 decrease in biomass burning is evident, not only in the Americas, but also g…

  • The effects of fire and tephra deposition on forest vegetation in the Central Cascades, Oregon

    Open AccessColin J Long, Mitchell J Power et al.ARTICLEQuaternary Research2011

    High-resolution charcoal and pollen analyses were used to reconstruct a 12,000-yr-long fire and vegetation history of the Tumalo Lake watershed and to examine the short-term effects that tephra deposition have on forest composition and fire regime. The record suggests that, from 12,000 to 9200 cal yr BP, the watershed was dominated by an open Pinus forest with Artemisia as a common understory species. Fire episodes occurred on average every 115 y…

  • Circum-Mediterranean fire activity and climate changes during the mid-Holocene environmental transition (8500-2500 cal. BP)

    Open AccessBoris Vannière, Mitchell J Power et al.ARTICLEThe Holocene2011Cited by: 19References: 46

    A mid- to late-Holocene synthesis of fire activity from the Mediterranean basin explores the linkages among fire, climate variability and seasonality through several climatic and ecological transitions. Regional fire histories were created from 36 radiocarbon-dated sedimentary charcoal records, available from the Global Charcoal Database. During the mid-Holocene ‘Thermal Maximum’ around 7500—4500 cal. BP, charcoal records from the northern Medite…

  • Peak detection in sediment–charcoal records: Impacts of alternative data analysis methods on fire-history interpretations

    P E Higuera, Daniel G Gavin et al.ARTICLEInternational Journal of Wildland…2010

    Over the past several decades, high-resolution sediment–charcoal records have been increasingly used to reconstruct local fire history. Data analysis methods usually involve a decomposition that detrends a charcoal series and then applies a threshold value to isolate individual peaks, which are interpreted as fire episodes. Despite the proliferation of these studies, methods have evolved largely in the absence of a thorough statistical framework.…

  • A 14,300-year-long record of fire–vegetation–climate linkages at Battle Ground Lake, southwestern Washington

    Open AccessMegan K Walsh, Cathy Whitlock et al.ARTICLEQuaternary Research2008

    High-resolution macroscopic charcoal analysis was used to reconstruct a 14,300-year-long fire history record from the lower Columbia River Valley in southwestern Washington, which was compared to a previous vegetation reconstruction for the site. In the late-glacial period (ca. 14,300-13,100 cal yr BP), Pinus / Picea -dominated parkland supported little to no fire activity. From the late-glacial to the early Holocene (ca. 13,100-10,800 cal yr BP)…

  • Climatic controls of Holocene fire patterns in southern South America

    Open AccessCathy Whitlock, Patricio I Moreno et al.ARTICLEQuaternary Research2007

    Holocene fire–climate–vegetation linkages are mostly understood at individual sites by comparing charcoal and pollen records with other paleoenvironmental proxy and model simulations. This scale of reconstruction often obscures detection of large-scale patterns in past fire activity that are related to changes in regional climate and vegetation. A network of 31 charcoal records from southern South America was examined to assess fire history along…

  • Holocene vegetation and fire history of the Coast Range, western Oregon, USA

    Open AccessColin J Long, Cathy Whitlock et al.ARTICLEThe Holocene2007Cited by: 3References: 3

    Pollen and high-resolution charcoal records from three lakes were examined to reconstruct the vegetation and fire history of the Oregon Coast Range for the last 9000 years. The sites are located along a north-to-south effective precipitation gradient and changes in vegetation and fire activity provided information on the nature of this gradient in the past. The relation of vegetation to climate change was examined at millennial timescales and the…

  • Postglacial vegetation, climate, and fire history along the east side of the Andes (lat 41–42.5°S), Argentina

    Open AccessCathy Whitlock, María Martha Bianchi et al.ARTICLEQuaternary Research2006

    The history of the low-elevation forest and forest-steppe ecotone on the east side of the Andes is revealed in pollen and charcoal records obtained from mid-latitude lakes. Prior to 15,000 cal yr BP, the vegetation was characterized by steppe vegetation with isolated stands of Nothofagus . The climate was generally dry, and the sparse vegetation apparently lacked sufficient fuels to burn extensively. After 15,000 cal yr BP, a mixture of Nothofagu…

  • Fire-fuel-climate linkages in the northwestern USA during the Holocene

    Open AccessJennifer R Marlon, Patrick J Bartlein et al.ARTICLEThe Holocene2006Cited by: 12References: 11

    Variations in fire regimes can be inferred from changes in the abundance of sedimentary charcoal found in lake and bog sediments. When analysed with pollen data, inferences can be made about past vegetation dynamics and climate as well. The analysis of high-resolution charcoal records generally involves the decomposition of charcoal influx into (a) a slowly varying ‘background’ component that provides information about long-term changes in region…

  • Postglacial vegetation, fire, and climate history of the Siskiyou Mountains, Oregon, USA

    Open AccessChristy E Briles, Cathy Whitlock et al.ARTICLEQuaternary Research2005

    The forests of the Siskiyou Mountains are among the most diverse in North America, yet the long-term relationship among climate, diversity, and natural disturbance is not well known. Pollen, plant macrofossils, and high-resolution charcoal data from Bolan Lake, Oregon, were analyzed to reconstruct a 17,000-yr-long environmental history of high-elevation forests in the region. In the late-glacial period, the presence of a subalpine parkland of Art…

  • A 9000-year fire history from the Oregon Coast Range, based on a high-resolution charcoal study

    Open AccessColin J Long, Cathy Whitlock et al.ARTICLECanadian Journal of Forest Research1998

    High-resolution analysis of macroscopic charcoal in sediment cores from Little Lake was used to reconstruct the fire history of the last 9000 years. Variations in sediment magnetism were examined to detect changes in allochthonous sedimentation associated with past fire occurrence. Fire intervals from ca. 9000 to 6850 calendar years BP averaged 110 ± 20 years, when the climate was warmer and drier than today and xerophytic vegetation dominated. F…

  • Stability of Holocene Climate Regimes in the Yellowstone Region

    Open AccessCathy Whitlock, Patrick J Bartlein et al.ARTICLEQuaternary Research1995

    A 12,500-yr pollen record from Loon Lake, Wyoming provides information on the climate history of the southwestern margin of Yellowstone National Park. The environmental reconstruction was used to evaluate hypotheses that address spatial variations in the Holocene climate of mountainous regions. Loon Lake lies within the summer-dry/winter-wet climate regime. An increase in xerophytic pollen taxa suggests drier-than-present conditions between ca. 9…

  • Spatial Variability of Late-Quaternary Paleoclimates in the Western United States

    Open AccessCary J Mock, Patrick J BartleinARTICLEQuaternary Research1995

    Paleoclimatic interpretation of proxy data is complicated sometimes by the appearance of heterogeneous patterns of climatic responses across networks of sites. Modern climate analogues for the western United States, similar to those patterns of atmospheric circulation of 18,000 and 9000 yr B.P., were examined in order to explain such patterns of spatial heterogeneity. Modern analogues were defined by comparing modern atmospheric circulation patte…

  • Calibration of Radiocarbon Ages and the Interpretation of Paleoenvironmental Records

    Open AccessPatrick J Bartlein, Mary E Edwards et al.ARTICLEQuaternary Research1995

    Calibration of the radiocarbon timescale of paleoecological records is essential if they are to be explained correctly in terms of their governing ecological or climatological controls. The differences between calendar ages and radiocarbon ages that arise from variations in 14C production through time can distort the chronologies of individual records and the interpretations based on them. Misleading impressions of synchrony or diachrony of event…
