Paleohydrologic reconstruction based on n-alkane distributions in ombrotrophic peat
TLDR
In this article, the authors demonstrate that ratios of the abundances of n-alkanes provide a new and efficient way of reconstructing past peatland surface moisture change, and find strong correlations among nalkane indices, humification indices and testate amoebae-inferred water table depths from a single core.About:

Leaf wax n-alkane distributions in and across modern plants: Implications for paleoecology and chemotaxonomy
TL;DR: It is shown that angiosperms generally produce more n-alkanes than do gymnosperms, and furthermore that CPI values show such variation in modern plants that it is prudent to discard the use of CPI as a quantitative indicator of n-alksane degradation in sediments.

Extracting the most from terrestrial plant-derived n-alkyl lipids and their carbon isotopes from the sedimentary record: A review
TL;DR: The factors that influence the concentration of plant biomarkers and their carbon isotope composition are reviewed and best practices for reconciling biomarker carbon isotopes records for interpreting climate, ecosystem, and carbon cycling in the geologic past are provided.

TL;DR: Peat depositional environments, the sites where and conditions under which peat accumulates, significantly influence a resultant coal's physical properties, chemical composition, and coal utilization behavior.

Lipid biomarkers in the Zoigê-Hongyuan peat deposit: Indicators of Holocene climate changes in West China
TL;DR: In this article, the authors extracted from a peat core obtained from the northeast edge of the Tibetan Plateau have provided a 13 kyr record of regional climate change, showing that a period of warmer climate corresponding to the Holocene Optimum between 9-ka and 5-ka is evident in greater alteration of nalkanoic acids and n-alkanols and in the appearance of biomarkers indicative of greater microbial activity.
Journal Article
Preparation and analysis of testate amoebae in peatland palaeoenvironmental studies
TL;DR: The use of testate amoebae in studies of peatland hydrology and palaeohydrology has been increasing, and considerable efforts have been made over the past decade to standardise techniques as much as possible as mentioned in this paper.

Leaf Epicuticular Waxes
G. Eglinton,Richard J. Hamilton +1 more
TL;DR: Enzymic studies, radiolabeling, and electron microscopy will be needed to reveal the mode of biogenesis of the wax constituents and their site of formation and subsequent pathway through the cuticle to the leaf surface.
Journal ArticleDOI
Applications of organic geochemistry to paleolimnological reconstructions: a summary of examples from the Laurentian Great Lakes
TL;DR: The organic matter content of lake sediments contains information that helps to reconstruct past environmental conditions, evaluate histories of climate change, and assess impacts of humans on local ecosystems as discussed by the authors, and serve as proxies of organic matter delivery and accumulation.
Journal ArticleDOI
An n-alkane proxy for the sedimentary input of submerged/floating freshwater aquatic macrophytes
TL;DR: In this article, a proxy ratio, Paq, was formulated to reflect the non-emergent aquatic macrophyte input to lake sediments relative to that from the emergent aquatic and terrestrial plants.

A sensitive high-resolution record of late Holocene climatic change from a raised bog in northern England:
TL;DR: In this paper, a 5 m core from Bolton Fell Moss, Cumbria, UK is used to demonstrate a strong correlation between changes in the relative proportion of taxa and known climatic changes over the last 1000 years.
