Considering both the possible changes of the ratio between the sediment amount remained in the modern Changjiang Delta and the sediment discharge of the Changjiang River in the postglacial period, and the changes of the sediment discharge, the authors believe that in the postglacial period, the sediment discharge of the Changjiang River is (2.36–4.86) × 10 8 tons/a on average, totaling to

These climatic fluctuations have resulted in the latitudinal shift of many organisms (Ha¨nfling and others 2002). The warm postglacial period and the postglacial climatic deterioration of northern Europe. Sernander, Rutger 1866-1944 (författare) Alternativt namn: Sernander, Johan Rutger, 1866-1944 2017-12-01 · The primary goal of this research was to illustrate how fire activity has varied in the Sunrise Ridge area of MORA during the postglacial period (the past ∼14,500 years). This area was chosen because of its proximity to the park's subalpine meadows, as well as several well-studied archaeological sites. Postglacial definition, after a given glacial epoch, especially the Pleistocene.

14,500 year-long environmental history shows variable fire activity during the postglacial. • Pollen analysis shows that modern-day forests established on Sunrise Ridge ∼7000 years ago. • Fire activity was highest on Sunrise Ridge during the past 4000 years when climate was cool and wet.

This slow progression is mostly due to climatic restrictions such as an estimated annual rainfall amount of only 64mm and a mean annual temperature of -19.7 degrees Celsius. The complexity of the glacial period and its subdivision into several glacial epochs, separated by interglacial epochs of considerable length (certainly longer than the postglacial epoch) has a structural consequence in the superposition of successive till sheets, alternating with non-glacial deposits, and also a physiographic consequence in the very different amount of normal postglacial erosion suffered by the different parts of the glacial deposits.

The changes in climate of the postglacial period have also left their marks upon the landscape, and there are many small-scale, but nevertheless significant features whose origin can be traced to these changes. There are prominent alluvial terraces which border the majority of the streams, large and small, in areas adjacent to the Rocky Mountains.

The colonial urochordate Botryllus schlosseri is a sedentary species of Mediterranean origin that became cosmopolitan, probably because of postglacial-period dispersal and human-mediated invasions of colonies attached to ship hulls.

2013-07-31 · This scenario may be paralleled in the history of haplogroups N1a1b1, I and W, with dispersals of haplogroups I and W into Europe during the Late Glacial period, ∼18–12 kya, signalled in particular by subclades I1, I2’3, I5, W3, W4 and W5, and by W1 in the immediate postglacial period, ∼10–11 kya.
