An increasing number of scientists recognize the value of speleothems1 as often extremely
well-preserved archives of information about past climate, vegetation, hydrology, sea level …

The application of stable isotopes in speleothem records requires an understanding of the
extent to which speleothem calcite isotopic compositions reflect the compositions of the cave …

This paper is a review of cave sediments: their characteristics and their application as
paleoclimate archives. Cave sediments can be separated into two broad categories, clastic …

Sky islands provide ideal opportunities for understanding how climatic changes associated
with Pleistocene glacial cycles influenced species distributions, genetic diversification, and …

Climatic changes associated with Pleistocene glacial cycles profoundly affected species
distributions, patterns of interpopulation gene flow, and demography. In species restricted to …

A primary step in the interpretation of speleothem stable isotope records (18O/16O and
13C/12C) is to conduct a comparison with other local palaeoclimate proxies. Here, two new …

Pollen, plant macrofossils, phytoliths, carbon isotopes, and alluvial history from sediments
exposed along the South Fork of the Big Nemaha River, southeastern Nebraska, USA …

The alluvial fill in the Upper Mississippi River Valley (UMV) is a palimpsest of past
landscapes, environments, and physical evidence of human life ways. The valley has …

Cave deposits of infill sediments and associated vertebrate fossils provide a valuable source
of information on terrestrial palaeoenvironments, climatic conditions and …

Most of the topography and drainage of the Mississippi River system has developed within
relatively recent geologic time. In contrast to the relative geographic stability for location of …
