    Life history variables preserved in dental cementum microstructure (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-08-27
    Description: The age and season of death of mammals, as well as other aspects of their life history, can be estimated from seasonal bands in dental cementum that result from variations in microstructure. Scanning electron micrographs of goats fed controlled diets demonstrate that cementum bands preserve variations in the relative orientation of collagen fibers that reflect changes in the magnitude and frequency of occlusal forces from chewing different quality diets. Changes in the rate of tissue growth are also reflected in cementum bands as variations in the degree of mineralization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lieberman, D E -- New York, N.Y. -- Science. 1993 Aug 27;261(5125):1162-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, Harvard University, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8356448" target="_blank"〉PubMed〈/a〉

    Periodicities of Polar Mesospheric Clouds Inferred from a Meteorological Analysis and Forecast System (2017)
    Wiley
    Details
    Publication Date: 2017-04-01
    Description: There is currently ambiguity in what controls polar mesospheric cloud (PMC) periodicities near 83 km altitude. This is primarily because satellite and ground-based datasets cannot resolve global mesospheric temperature variability over the diurnal cycle. To address this limitation, we employ a global meteorological analysis and forecast system that assimilates mesospheric satellite data with two significant advances. The first is that we use output at a more rapid one hourly cadence, allowing for a quantitative description of diurnal (24 h), semi-diurnal (12 h), and terdiurnal oscillations. The second is that the output drives a simple PMC parameterization which depends only on the local temperature, pressure and water vapor concentrations. Our study focuses on results from July 2009 in the northern hemisphere and January 2008 in the southern hemisphere. We find that the 24 h migrating temperature tide as well as the 12 h and 24 h nonmigrating tides dominate northern PMC oscillations whereas the 12 h and 24 h nonmigrating tides dominate southern oscillations. Monthly averaged amplitudes for each of these components are generally 2-6 K with the larger amplitudes at lower PMC latitudes (50°). The 2 day and 5 day planetary waves also contribute in both hemispheres, with monthly averaged amplitudes from 1-3 K although these amplitudes can be as high as 4-6 K on some days. Over length scales of ~1000 km and time scales of ~1 week, we find that local temperature oscillations adequately describe mid-latitude PMC observations.
