Lipid Biomarkers and Pertinent Indices From Aquatic Environment Record Paleoclimate and Paleoenvironment Changes [PDF]
Quaternary Science Reviews, 2015 Lipid biomarkers and their pertinent indices have been used as the most effective proxies for paleoclimate and paleoenvironment conditions. This paper conducts a systematic review on a variety of lipid biomarkers in aquatic sediments and water column ...

The paleoenvironment ofSivapithecus parvada
Journal of Human Evolution, 1999Remains of the hominoid Sivapithecus parvada and a diversity of mammalian taxa are preserved at locality Y311 (ca. 10 Ma) in the Siwalik Nagri Formation of northern Pakistan. Bovids (Bovidae, Artiodactyla) are the most abundant mammals next to tragulids (Tragulidae, Artiodactyla) at locality Y311 and provide a means for reconstructing the ...

BIOMARKERS AS INDICATORS OF PALEOENVIRONMENT
XXX International Interdisciplinary Scientific Conference «Man and Nature: Priorities of Modern Research in the Area of Interaction of Nature and Society», 2021Biomarkers, due to their specific structure and biochemical functions, under certain environmental conditions are resistant to degradation and mineralization in soils and therefore serve as molecular traces of paleobiota and terrestrial vegetation, as well as the intensity of biochemical processes occurring in the biosphere not only in the present, but

Abstract One of the most fascinating facets of eDNA lies in the possibility of exploiting it to reconstruct past environments in paleoecology and in archaeology. Chapter 15, entitled “Paleoenvironments,” reviews different pioneer studies that scrutinized ancient eDNA extracted from different substrates (e.g., lake sediments, permafrost ...

Paleoenvironment and Paleoclimate
2015Microfossils are key to the interpretation of paleoenvironment, including the estimation of sea-level change, oceanic productivity, amount of dissolved oxygen in seawater and paleoclimate. Foraminiferal assemblages are indicators of sea-level change. The common foraminiferal genera of different depth zones on the shelf, slope and abyssal plain of the ...

From micromammals to paleoenvironments
Archaeological and Anthropological Sciences, 2018Micromammal assemblages are often used in paleoecological reconstructions. However, in studies to date, the environmental variables reconstructed were not shown to drive micromammal community structure before the reconstruction was attempted. Furthermore, the relative abundance data is too often dismissed despite its potential paleoecological value ...
