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...

Holocene forest dynamics in southern Ontario, Canada: fine-resolution pollen data
TL;DR: Subsequent forest dynamics are discussed in terms of the main factors driving vegetation change, including climate, soil development, migration, disturbance regime, and competition, which operate on a species pool with a variety of biological and ecological characteristics.

Climate-related eutrophication of a small boreal lake in northwestern Ontario: a palaeolimnological perspective:
TL;DR: A palaeolimnological investigation of changes in water quantity and quality in Lake 239, Experimental Lakes Area, in northwestern Ontario indicates marked changes in limnological conditions during the Holocene as mentioned in this paper.
Journal ArticleDOI
Successions of invertebrate microfossils and the late quaternary deglaciation of the central St Lawrence Lowland, Canada and United States
TL;DR: Foraminiferal and ostracode assemblages in late glacial and early postglacial sediments of the Central St Lawrence Lowland show that a proglacial lake (Glacial Lake St Lawrence) preceded the Champlain Sea in some parts of the lowland, and that the Chambourne Sea was in contact with the Laurentide Ice Sheet during deglaciation.

Aulacoseira subborealis stat nov (Bacillariophyceae): a common but neglected plankton diatom
TL;DR: Aulacoseira subborealis is widely distributed in rivers and lakes in W-Europe and Australia, and presumably occurs in New Zealand and North America as well, but has been reported only rarely because of confusion with other taxa.
Book ChapterDOI
The mythical concept of eutrophication
TL;DR: The authors argue that this term is often used incorrectly and that alternative explanations can serve as more accurate descriptions, such as increased organic content in the sedimentary record may result from increased nutrient availability (eutrophication), but it can also reflect decreased residence time of water, or changes in biotic interactions, and changes in lake morphometry.
