 Genetic variation maintained in multilocus models of additive quantitative traits under stabilizing selectionR Burger
Institut für Mathematik, Universitat Wien, A 1090 Vienna, Austria
Genetics 152:80720. 1999..The expected genetic variance, the expected polymorphic fraction of the genome, as well as other quantities of interest, are only weakly dependent on the selection intensity and the level of recombination...  Evolution and polymorphism in the multilocus Levene model with no or weak epistasisReinhard Burger
Department of Mathematics, University of Vienna, Austria
Theor Popul Biol 78:12338. 2010..e., by nonepistatic loci with dominance. Some of our results are exemplified in this quantitativegenetic context...  Polymorphism in the twolocus Levene model with nonepistatic directional selectionReinhard Burger
Department of Mathematics, University of Vienna, Austria
Theor Popul Biol 76:21428. 2009..If the favorable allele is (partially) dominant in its deme, more than 20% of all parameter combinations lead to a globally asymptotically stable, fully polymorphic equilibrium...  Multilocus selection in subdivided populations II. Maintenance of polymorphism under weak or strong migrationReinhard Burger
Department of Mathematics, University of Vienna, Vienna, Austria
J Math Biol 58:97997. 2009..Thus, several scenarios are identified under which multilocus polymorphism can be maintained by migrationselection balance when this is impossible in a panmictic population...  Multilocus selection in subdivided populations I. Convergence properties for weak or strong migrationReinhard Burger
Department of Mathematics, University of Vienna, Vienna, Austria
J Math Biol 58:93978. 2009..In both cases, every trajectory converges to an equilibrium, thus no cycling or complicated dynamics can occur...  The conditions for speciation through intraspecific competitionReinhard Burger
Department of Mathematics, University of Vienna, Nordbergstrasse 15, 1090 Vienna, Austria
Evolution 60:2185206. 2006..On the methodological side, we propose quantitative measures for deciding whether a given distribution reflects two (or more) reproductively isolated clusters...  Intraspecific competitive divergence and convergence under assortative matingReinhard Burger
Department of Mathematics, University of Vienna, Nordbergstrasse 15, 1090 Vienna, Austria
Am Nat 167:190205. 2006..Even then, the evolutionary outcome depends on the genetics and the initial conditions. The roles of the number of loci, of linkage, and of asymmetric selection are also explored...  A multilocus analysis of intraspecific competition and stabilizing selection on a quantitative traitReinhard Burger
Department of Mathematics, University of Vienna, Austria
J Math Biol 50:35596. 2005..For two loci, the effects of linkage are investigated analytically; for several loci, they are studied numerically...  The effects of intraspecific competition and stabilizing selection on a polygenic traitReinhard Burger
Department of Mathematics, University of Vienna, A 1090 Vienna, Austria
Genetics 167:142543. 2004..Consequences for the maintenance of genetic variation, the detection of disruptive selection, and models of sympatric speciation are discussed...  Fluctuating environments and the role of mutation in maintaining quantitative genetic variationReinhard Burger
Department of Mathematics, University of Vienna, Vienna, Austria
Genet Res 80:3146. 2002..We investigate how the genetic variation maintained depends on the ecological parameters and on the underlying genetics...  Additive genetic variation under intraspecific competition and stabilizing selection: a twolocus studyReinhard Burger
Institut für Mathematik, Universitat Wien, A 1090 Wien, Austria
Theor Popul Biol 61:197213. 2002..For unequal effects, disruptive selection can be observed for weaker competition and in the absence of a stable polymorphism...  Evolution of genetic variability and the advantage of sex and recombination in changing environmentsR Burger
Institut für Mathematik, Universitat Wien, A 1090 Wien, Austria and International Institute of Applied Systems Analysis, A 2361 Laxenburg, Austria
Genetics 153:105569. 1999..In particular, it is elucidated how this change in genetic variance depends on the reproductive system, the population size, and the selective regime, and what the consequences for population persistence are...  The effects of linkage and gene flow on local adaptation: a twolocus continentisland modelReinhard Burger
Department of Mathematics, University of Vienna, Austria
Theor Popul Biol 80:27288. 2011..We discuss possible consequences for the evolution of genetic architecture, in particular, for the emergence of clusters of tightly linked, slightly beneficial mutations and the evolution of recombination and chromosome inversions...  The twolocus model of Gaussian stabilizing selectionMartin Willensdorfer
Department of Mathematics, University of Vienna, Vienna, Austria
Theor Popul Biol 64:10117. 2003..The results are compared with previous analyses of the special case of extremely strong selection, of an approximate model that assumes linkage equilibrium, and of the much simpler quadratic optimum model...  Evolution of dominance under frequencydependent intraspecific competitionStephan Peischl
Department of Mathematics, University of Vienna, Nordbergstrasse 15, 1090 Wien, Austria
J Theor Biol 251:21026. 2008..It also demonstrates that an invasion analysis of mutants of very small effect is insufficient to obtain a full understanding of the evolutionary dynamics under frequencydependent selection...
