The Biomarker Guide
TL;DR: The second edition of The Biomarker Guide as mentioned in this paper provides a comprehensive account of the role that biomarker technology plays both in petroleum exploration and in understanding Earth history and processes.
Book ChapterDOI
Fatty acid trophic markers in the pelagic marine environment.
TL;DR: A conceptual model of the spatial and temporal dominance of group-specific primary producers, and hence the basic fatty acid patterns available to higher trophic levels is presented and is based on stratification.

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
School Climate: Research, Policy, Practice, and Teacher Education
TL;DR: A sustainable, positive school climate fosters youth development and learning necessary for a productive, contributive, and satisfying life in a democratic society as mentioned in this paper, including norms, goals, values, interpersonal relationships, teaching and learning practices, and organizational structures.
Journal ArticleDOI
Lacustrine sedimentary organic matter records of Late Quaternary paleoclimates
TL;DR: For example, despite the extensive early diagenetic losses of organic matter in general and of some of its important biomarker compounds in particular, bulk identifiers appear to undergo minimal alteration after sedimentation as discussed by the authors.

TL;DR: Pore water profiles of total CO 2, pH, PO 3−4, NO − 3 plus NO − 2, SO 2− 4, S 2−, Fe 2+ and Mn 2+ have been obtained in cores from pelagic sediments of the eastern equatorial Atlantic under waters of moderate to high productivity as mentioned in this paper.
Journal ArticleDOI
Preservation of elemental and isotopic source identification of sedimentary organic matter
TL;DR: The amount and type of organic matter in the sediments of lakes and oceans contribute to their paleoenvironmental and paleoclimatological records as discussed by the authors, but only a small fraction of the initial aquatic organic matter survives destruction and alteration during sinking and sedimentation.

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
Carbon Isotopes in PhotosynthesisFractionation techniques may reveal new aspects of carbon dynamics in plants
TL;DR: The fractionation of carbon isotopes that occurs during photosynthesis is one of the most useful techniques for investigating the efficiency of CO2 uptake and indicates that different strategies are needed for improving wateruse efficiency in different kinds of plants.
