Current practices in building and reporting age-depth models
Terri Lacourse,Konrad Gajewski +1 more
TL;DR: In this article, the authors present a case study of building age-depth models for a lake sediment core that has both 14C ages and an independent varve chronology, and show that choosing the best model is not a simple task, and that model accuracy is ultimately controlled by differences between 14c ages and true age that likely occur in many late Quaternary records.
The climate of North America during the past 2,000 years reconstructed from pollen data
TL;DR: In this article, the temperature of the warmest month was reconstructed for the past 2000 years using 748 pollen sites from the North American Pollen Database using the Modern Analog Technique.

The long-term impacts of climate and fire on catchment processes and aquatic ecosystem response in Tasmania, Australia
Kristen K. Beck,Kristen K. Beck,Michael-Shawn Fletcher,Patricia Gadd,Henk Heijnis,Krystyna M. Saunders,Atun Zawadzki +6 more
TL;DR: A 9200 year Holocene record of sedimentary Carbon/Nitrogen, x-ray fluorescence, charcoal, pollen, and diatoms preserved within a freshwater lake in Tasmania was used to understand the influences of climate variability and fire on aquatic ecosystem response.
Journal ArticleDOI
Flood variability in the common era: a synthesis of sedimentary records from Europe and North America
TL;DR: In this paper, the authors show that heavy precipitation events increased over the last century in response to higher atmospheric temperature and associated increases in water vapor content, but little evidence shows that increased he...

Late holocene climate changes in eastern North America estimated from pollen data
TL;DR: In this paper, a well-dated pollen profile from six sites from Maine to Minnesota recorded vegetation changes indicative of summer temperature and annual precipitation variations over the past 2000 yr. Multiple regression techniques were used to calculate calibration functions from a spatial network of modern pollen and climate data.
Journal ArticleDOI
A climatic driver for abrupt mid‐holocene vegetation dynamics and the hemlock decline in new england
TL;DR: P paleoecological evidence implicating climate as a major driver of the mid-Holocene decline of eastern hemlock is reported, and the potential for climate change to generate major, abrupt dynamics in forest ecosystems is highlighted.
Journal ArticleDOI
Widespread evidence of 1500 yr climate variability in North America during the past 14 000 yr
TL;DR: In this article, the authors show that millennial-scale climate variability caused changes in vegetation communities across all of North America with a periodicity of 1650 ± 500 yr during the past 14'000 calendar years (cal yr).
Journal ArticleDOI
Diatom assemblages as indicators of lake trophic status in southeastern ontario lakes1
TL;DR: Canonical correspondence analysis was used to explore the relationship between measured environmental variables and surficial diatom assemblages in alkaline lakes from southeastern Ontario and found total nitrogen, watershed area, alkalinity, and maximum depth each explain significant directions of variance in the distribution of diatom taxa.

The relative influences of climate and catchment processes on Holocene lake development in glaciated regions
TL;DR: In this article, the authors provide a conceptual model of some dominant pathways of catchment influence on long-term lake development in glaciated regions and use a series of paleolimnological examples from arctic, boreal, and temperate regions to evaluate the relative role of direct climate influences and of catchments processes in affecting the trajectory of aquatic ecosystems during the Holocene in different environmental contexts.
