Intra-deme molecular diversity in spatially expanding populationsNicolas Ray
Genetics and Biometry Lab, Department of Anthropology and Ecology, University of Geneva, Geneva, Switzerland
Mol Biol Evol 20:76-86. 2003..The fact that molecular diversity within deme is so dependent on recent levels of gene flow suggests that it should be possible to estimate Nm values from samples drawn from a single deme...- Rise of oceanographic barriers in continuous populations of a cetacean: the genetic structure of harbour porpoises in Old World watersMichael C Fontaine
MARE Laboratory for Oceanology, University of Liege, Bat B6c, Liege Sart Tilman, Belgium
BMC Biol 5:30. 2007.... - Recovering the geographic origin of early modern humans by realistic and spatially explicit simulationsNicolas Ray
Computational and Molecular Population Genetics Lab, Zoological Institute, University of Bern, 3012 Bern, Switzerland
Genome Res 15:1161-7. 2005..A new estimation modeling this bias explicitly reveals that East Africa is the most likely place of origin for modern humans... - AccessMod 3.0: computing geographic coverage and accessibility to health care services using anisotropic movement of patientsNicolas Ray
Information, Evidence and Research, World Health Organization, 20 av, Appia, 1211 Geneva 27, Switzerland
Int J Health Geogr 7:63. 2008..Combining these two types of measure into a single index provides a measure of geographic (or spatial) coverage, which is an important measure for assessing the degree of accessibility of a health care network... - Inferring past demography using spatially explicit population genetic modelsNicolas Ray
Computational and Molecular Population Genetics Lab, Institute of Ecology and Evolution, University of Bern, 3012 Bern, Switzerland
Hum Biol 81:141-57. 2009.... - Surfing during population expansions promotes genetic revolutions and structurationLaurent Excoffier
Computational and Molecular Population Genetics Lab, Institute of Zoology, University of Berne, Baltzerstrasse 6, Berne, Switzerland
Trends Ecol Evol 23:347-51. 2008..They also suggest that a single range expansion can create very complex patterns at neutral loci, mimicking adaptive processes and resembling postglacial segregation of clades from distinct refuge areas... - Colonization history of the Swiss Rhine basin by the bullhead (Cottus gobio): inference under a Bayesian spatially explicit frameworkSamuel Neuenschwander
CMPG, Zoological Institute, University of Bern, Baltzerstrasse 6, 3012 Bern, Switzerland
Mol Ecol 17:757-72. 2008..We discuss the implication of this result, as well as the strengths and limits of the spatially explicit approach coupled to the approximate Bayesian computation framework... - Bayesian estimation of recent migration rates after a spatial expansionGrant Hamilton
Computational and Molecular Population Genetics Lab, Zoological Institute, University of Bern, Switzerland
Genetics 170:409-17. 2005..Estimates based on both markers suggest that expansion occurred <10,000 years ago, after the most recent glaciation, and that migration rates are strongly male biased... - Consequences of range contractions and range shifts on molecular diversityMiguel Arenas
Computational and Molecular Population Genetics Lab, Institute of Ecology and Evolution, University of Bern, Berne, Switzerland
Mol Biol Evol 29:207-18. 2012..It also implies that a given episode of climatic change will impact differently species with different generation times... - Statistical evaluation of alternative models of human evolutionNelson J R Fagundes
Laboratório de Biologia Genômica e Molecular, Faculdade de Biociencias, Pontificia Universidade Catolica do Rio Grande do Sul, 90619 900 Porto Alegre, RS, Brazil
Proc Natl Acad Sci U S A 104:17614-9. 2007.... - Geographic patterns of genome admixture in Latin American MestizosSijia Wang
The Galton Laboratory, Department of Biology, University College London, London, United Kingdom
PLoS Genet 4:e1000037. 2008..Our findings agree with available information on the demographic history of Latin America and have a number of implications for the design of association studies in population from the region... - Comment on "Ongoing adaptive evolution of ASPM, a brain size determinant in Homo sapiens" and "Microcephalin, a gene regulating brain size, continues to evolve adaptively in humans"Mathias Currat
Department of Zoology, University of British Columbia, Vancouver, BC V6T 1Z4, Canada
Science 313:172; author reply 172. 2006..We show that models of human history that include both population growth and spatial structure can generate the observed patterns without selection... - Genetic variation and population structure in native AmericansSijia Wang
The Galton Laboratory, Department of Biology, University College London, London, United Kingdom
PLoS Genet 3:e185. 2007..These findings offer new insights into the process of population dispersal and differentiation during the peopling of the Americas...
