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.
Journal ArticleDOI
Influence of temperature and C4 abundance on n-alkane chain length distributions across the central USA
TL;DR: The data suggest that the spatial and temporal variation in chain length distributions observed in studies of sediment archives may be driven in large part by growing season temperature and/or aridity rather than photosynthetic pathway (C3 or C4).

The 6-methyl branched tetraethers significantly affect the performance of the methylation index (MBT′) in soils from an altitudinal transect at Mount Shennongjia
TL;DR: Wang et al. as mentioned in this paper analyzed the brGDGTs in soils from Mt. Shennongjia using an improved liquid chromatography method and examined whether the newly described 6-methyl brDGTs were the main cause of the large scatter in the correlation between MBT and MAT.

Biology in the Anthropocene: Challenges and insights from young fossil records
TL;DR: Young fossil records provide rigorous access to the baseline composition and dynamics of modern-day biota under pre-Industrial conditions, where insights include the millennial-scale persistence of community structures, the dominant role of physical environmental conditions rather than biotic interactions in determining community composition and disassembly, and the existence of naturally alternating states.

Book
Plant Physiological Ecology
TL;DR: This textbook is notable in emphasizing that the mechanisms underlying plant physiological ecology can be found at the levels of biochemistry, biophysics, molecular biology and whole-plant physiology, well-suited to assess the costs, benefits and consequences of modifying plants for human needs, and to evaluate the role of plants in ecosystems.
Book
Treatise on geochemistry
TL;DR: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry as discussed by the authors.

A High-Resolution Absolute-Dated Late Pleistocene Monsoon Record from Hulu Cave, China
Yongjin Wang,Yongjin Wang,Hai Cheng,Richard Lawrence Edwards,Zhisheng An,Jiangying Wu,Chuan-Chou Shen,Jeffrey A. Dorale +7 more
TL;DR: The record links North Atlantic climate with the meridional transport of heat and moisture from the warmest part of the ocean where the summer East Asian Monsoon originates and generally agrees with the timing of temperature changes from the Greenland Ice Sheet Project Two (GISP2).
Journal ArticleDOI
Archaea in coastal marine environments.
TL;DR: Evidence for the widespread occurrence of unusual archaea in oxygenated coastal surface waters of North America is provided and it is suggested that these microorganisms represent undescribed physiological types of archaea, which reside and compete with aerobic, mesophilic eubacteria in marine coastal environments.

Isolation of an autotrophic ammonia-oxidizing marine archaeon
Martin Könneke,Anne E. Bernhard,Anne E. Bernhard,José R. de la Torre,Christopher B. Walker,John B. Waterbury,David A. Stahl +6 more
TL;DR: The isolation of a marine crenarchaeote that grows chemolithoautotrophically by aerobically oxidizing ammonia to nitrite—the first observation of nitrification in the Archaea is reported, suggesting that nitrifying marine Cren archaeota may be important to global carbon and nitrogen cycles.
