An aminostratigraphy of the northern Upper Rhine Graben, Germany

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern Upper Rhine Graben (Germany) contains a complex, quasi‐continuous Quaternary record, but constraining its chronology is challenging. This study presents the first application of amino acid geochronology for this region using Bithynia opercula to establish a relative dating framework.

The Holocene sedimentary record of Mittie Glacier dynamics in Smith Bay, Ellesmere Island (eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, EarlyView.
ABSTRACT The physical, sedimentological, mineralogical, and elemental geochemical properties of sediment cores collected in Smith Bay (22BC and 01PC), and near the front of Mittie Glacier (23BC and 01GC), were used to reconstruct glacial sediment discharge and trace the long‐term composition and provenance of detrital sediments for the northeastern ...

A tephrostratigraphic investigation of the continuously varved Holocene Boreal lake Nautajärvi, Finland, provides precise age estimate for Lairg A/Hekla 5 eruption

Journal of Quaternary Science, EarlyView.
ABSTRACT Numerous cryptotephra layers originating from Icelandic volcanoes and further afield have reached Northern Europe during the Holocene. Refining the precise timing and the relative frequency of local and distal eruptions requires well‐resolved continuous sediment archives. Lake Nautajärvi is located in central‐southern Finland (61°48′ N, 24°41′

Entropic Sampling and Natural Selection in Biological Evolution

, 1998
With a view to connecting random mutation on the molecular level to punctuated equilibrium behavior on the phenotype level, we propose a new model for biological evolution, which incorporates random mutation and natural selection.

Mountainous vegetation succession and land use during the last millennium in the Peloponnese (southern Greece): Environmental change and economic development in an isolated periphery

Journal of Quaternary Science, EarlyView.
ABSTRACT Mediterranean mountainous areas and their valuable natural resources have long been attractive to human societies. The Peloponnese (southern Greece), with its complex topographic and climatic variability, has been the scenery for the development of numerous human communities.

The Constitution of Paleobiological Data

, 2015
The objective of this dissertation is to write the first pages of the biography of paleobiological data. I will focus on i) the genesis of this kind of data as it emerged in German stratigraphy and paleontology between the mid 19th and the early 20th centuries and ii) how the conceptualization of the paleontological data was reformulated and taken as ...

Middle to Late Pleistocene valley‐slope cambering: The interglacial basin at Wing, Rutland, England

Journal of Quaternary Science, EarlyView.
ABSTRACT A depression in the Jurassic bedrock at Wing, Rutland (eastern England), is infilled by deposits spanning the Late Wolstonian (=Late Saalian) to Early Devensian (=Early Weichselian) substages, including the most complete Ipswichian Stage (=Eemian Stage; ~Marine Isotope Stage 5e) sequence known in Britain. This sequence forms an enclosed pocket,
