    A virus reveals population structure and recent demographic history of its carnivore host (2006)

    Publikationsdatum: 2006-01-28
    Beschreibung: Directly transmitted parasites often provide substantial information about the temporal and spatial characteristics of host-to-host contact. Here, we demonstrate that a fast-evolving virus (feline immunodeficiency virus, FIV) can reveal details of the contemporary population structure and recent demographic history of its natural wildlife host (Puma concolor) that were not apparent from host genetic data and would be impossible to obtain by other means. We suggest that rapidly evolving pathogens may provide a complementary tool for studying population dynamics of their hosts in "shallow" time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biek, Roman -- Drummond, Alexei J -- Poss, Mary -- New York, N.Y. -- Science. 2006 Jan 27;311(5760):538-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wildlife Biology Program, University of Montana, Missoula, MT 59812, USA. rbiek@emory.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16439664" target="_blank"〉PubMed〈/a〉

    Language phylogenies reveal expansion pulses and pauses in Pacific settlement (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-01-24
    Beschreibung: Debates about human prehistory often center on the role that population expansions play in shaping biological and cultural diversity. Hypotheses on the origin of the Austronesian settlers of the Pacific are divided between a recent "pulse-pause" expansion from Taiwan and an older "slow-boat" diffusion from Wallacea. We used lexical data and Bayesian phylogenetic methods to construct a phylogeny of 400 languages. In agreement with the pulse-pause scenario, the language trees place the Austronesian origin in Taiwan approximately 5230 years ago and reveal a series of settlement pauses and expansion pulses linked to technological and social innovations. These results are robust to assumptions about the rooting and calibration of the trees and demonstrate the combined power of linguistic scholarship, database technologies, and computational phylogenetic methods for resolving questions about human prehistory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, R D -- Drummond, A J -- Greenhill, S J -- New York, N.Y. -- Science. 2009 Jan 23;323(5913):479-83. doi: 10.1126/science.1166858.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Auckland, Private Bag 92019, Auckland 1142, New Zealand.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19164742" target="_blank"〉PubMed〈/a〉
