Polymorphism and transcription of Mhc class I genes in a passerine bird, the great reed warblerH Westerdahl
Department of Animal Ecology, Lund University, Ecology Building, S 223 62 Lund, Sweden
Immunogenetics 49:158-70. 1999..The number of transcribed genes and the numerous RFLP fragments found so far suggest that the great reed warbler does not have a "minimal essential Mhc" as has been suggested for the chicken...- Mhc diversity in two passerine birds: no evidence for a minimal essential MhcH Westerdahl
Department of Animal Ecology, Lund University, Sweden
Immunogenetics 52:92-100. 2000..This difference could be caused by their phylogenetic past, and/or by variance in the selection pressure for maintaining a high number of Mhc genes... - Associations between malaria and MHC genes in a migratory songbirdHelena Westerdahl
Department of Animal Ecology, Lund University, Ecology Building, 223 62 Lund, Sweden
Proc Biol Sci 272:1511-8. 2005..These associations suggest that individuals carrying either a large number of MHC alleles or a specific MHC allele are protected against lethal malaria infections... - Between-year variation of MHC allele frequencies in great reed warblers: selection or drift?H Westerdahl
Department of Animal Ecology, Lund University, Sweden
J Evol Biol 17:485-92. 2004..These results imply that the variation in MHC allele frequencies between cohorts is not a result of demographic events, but rather an effect of selection favouring different MHC alleles in different years... - MHC class I typing in a songbird with numerous loci and high polymorphism using motif-specific PCR and DGGEH Westerdahl
Department of Animal Ecology, Ecology Building, Lund University, S 223 62 Lund, Sweden
Heredity (Edinb) 92:534-42. 2004..In our study population of great reed warblers, we found a high level of genetic variation in MHC class I, and no less than 234 DGGE genotypes were detected among 248 screened individuals... - No evidence of an MHC-based female mating preference in great reed warblersHelena Westerdahl
Department of Animal Ecology, Ecology Building, Lund University, S 223 62 Lund, Sweden
Mol Ecol 13:2465-70. 2004..Power analyses of the data sets revealed that relatively small differences (15% and 8%, respectively) between true and random pairs should have been detected... - Host specificity in avian blood parasites: a study of Plasmodium and Haemoproteus mitochondrial DNA amplified from birdsS Bensch
Department of Animal Ecology, Lund University, Sweden
Proc Biol Sci 267:1583-9. 2000..Hence, host shifts seem to have occurred repeatedly in this parasite host system. We discuss this in terms of the possible evolutionary consequences for these bird species... - Observation of a ZZW female in a natural population: implications for avian sex determinationD Arit
Department of Animal Ecology, Lund University, Ecology Building, S-223 62 Lund, Sweden
Proc Biol Sci 271:S249-51. 2004..Our data strongly suggest a role of W-linked genes in avian sex determination... - Does linkage disequilibrium generate heterozygosity-fitness correlations in great reed warblers?Bengt Hansson
Department of Animal Ecology, Ecology Building, Lund University, S 223 62 Lund, Sweden
Evolution 58:870-9. 2004..Our present finding of a significant within-family multilocus heterozygosity-survival association in a nonequilibrium population supports the view that LD generates HFCs in natural populations... - MHC diversity in two Acrocephalus species: the outbred Great reed warbler and the inbred Seychelles warblerDavid S Richardson
Department of Animal Ecology, Ecology Building, Lund University, S 223 62 Lund, Sweden
Mol Ecol 12:3523-9. 2003..There was evidence for balancing selection in both species, and the phylogenetic analysis showing that the exon 3 sequences did not separate according to species, was consistent with transspecies evolution of the MHC... - Temporal dynamics and diversity of avian malaria parasites in a single host speciesStaffan Bensch
Department of Animal Ecology, Ecology Building, Lund University, S 223 62 Lund Sweden
J Anim Ecol 76:112-22. 2007....

Molecular Ecology and Evolution Lab, Department of Biology, Lund University, Lund, Sweden
J Evol Biol 24:1232-40. 2011..To obtain a comprehensive understanding of evolutionary processes in host-parasite systems, both innate and acquired immunity thus need to be considered...- An Mhc class I allele associated to the expression of T-dependent immune response in the house sparrowCamille Bonneaud

Immunogenetics 57:782-9. 2005..Our results point toward a contribution of the Mhc, or of other genes in linkage disequilibrium with the Mhc, in the regulation of immune responses in a wild animal species... - Complex Mhc-based mate choice in a wild passerineCamille Bonneaud
Laboratoire de Parasitologie Evolutive, CNRS UMR 7103, Universite Pierre et Marie Curie Paris 6, 7 quai St Bernard, bât A 7ème étage, Case 237, Paris 75252 Cedex 05, France
Proc Biol Sci 273:1111-6. 2006..These results suggest that mate choice evolves in response to (i) benefits in terms of parasite resistance acquired from allelic diversity, and (ii) costs associated with the disruption of co-adapted genes... - Diversity of Mhc class I and IIB genes in house sparrows (Passer domesticus)Camille Bonneaud
Centre National de la Recherche Scientifique Unité Mixte de Recherche 7103, Universite Pierre et Marie Curie, Batiment A, 7e étage, 7 quai St Bernard, Case 237, 75252 Paris, Cedex 05, France
