- Genetic load in sexual and asexual diploids: segregation, dominance and genetic driftChristoph R Haag
University of Edinburgh, Institute of Evolutionary Biology, Edinburgh EH9 3JT, United Kingdom
Genetics 176:1663-78. 2007..Overall, the mutation load that arises through the absence of segregation in asexuals may greatly exceed previous predictions that ignored genetic drift...

University of Helsinki, Department of Biological and Environmental Sciences, PO Box 65, 00014 Helsinki, Finland
Proc Biol Sci 272:2449-56. 2005..These results also contribute to an emerging understanding of the mechanisms by which population turnover in heterogeneous landscapes may maintain genetic and phenotypic variation across populations...

- Fitness differences associated with Pgi SNP genotypes in the Glanville fritillary butterfly (Melitaea cinxia)L Orsini
Metapopulation Research Group, Department of Biological and Environmental Sciences, University of Helsinki, Helsinki, Finland
J Evol Biol 22:367-75. 2009..Although this is consistent with direct overdominance at Pgi, we cannot exclude the possibility that heterozygote advantage is caused by the presence of one or more deleterious alleles at linked loci...
- Nucleotide polymorphism and within-gene recombination in Daphnia magna and D. pulex, two cyclical parthenogensChristoph R Haag

- Parasite-mediated selection in experimental metapopulations of Daphnia magnaChristoph R Haag
Universite de Fribourg, Department de Biologie, Unité d Ecologie et d Evolution, GH 1700 Fribourg, Switzerland
Proc Biol Sci 271:2149-55. 2004..Taken together, our results suggest that parasite strains that invade local host populations can lead to evolutionary changes in the genetic composition of the host population and that this change is parasite-species specific...
- Experimental evolution of field populations of Daphnia magna in response to parasite treatmentM Zbinden
Departement de Biologie, Unité d Ecologie et d Evolution, Universite de Fribourg, Fribourg, Switzerland
J Evol Biol 21:1068-78. 2008..Overall, our results show that, under natural conditions, Daphnia populations are able to adapt rapidly to the prevailing conditions and that this evolutionary change is specific to the environment...
- Nucleotide polymorphism at a gene (Pgi) under balancing selection in a butterfly metapopulationChristopher W Wheat
Department of Biological and Environmental Sciences, University of Helsinki, Finland
Mol Biol Evol 27:267-81. 2010..cinxia and the unrelated Colias eurytheme butterfly suggests a similar but not identical target of balancing selection. Our results indicate convergent evolution between these two species at both the phenotypic and molecular levels...
- Test of synergistic interaction between infection and inbreeding in Daphnia magnaChristoph R Haag
Universite de Fribourg, Departement de Biologie, Unité d Ecologie et d Evolution, Chemin du Musee 10, CH 1700 Fribourg, Switzerland
Evolution 57:777-83. 2003..Our findings also indicate that there is variation for specific resistance to different species of parasites in the meta-population from which the hosts for this study were obtained...
- Strong inbreeding depression in a Daphnia metapopulationChristoph R Haag
Universitat Basel, Zoologisches Institut, Switzerland
Evolution 56:518-26. 2002..However, the finding of low inbreeding depression in the monoclonal populations suggests that inbred and outbred genotypes might have about equal chances of establishing new populations...
