Grandparent helpers: the adaptive significance of older, postdominant helpers in the Seychelles warblerDavid S Richardson
Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich, NR4 7TJ, United Kingdom
Evolution 61:2790-800. 2007..As direct benefits appeared to be limited, we suggest that indirect benefits have driven the evolution of such "grandparent helpers." This study now provides evidence for a new route to cooperative breeding in birds...- Inbreeding in the Seychelles warbler: environment-dependent maternal effectsDavid S Richardson
Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, United Kingdom
Evolution 58:2037-48. 2004..Our results show that inbreeding can have complicated effects even within a genetic bottlenecked population where the "purging" of recessive alleles is expected to reduce the effects of inbreeding depression... - MHC-based patterns of social and extra-pair mate choice in the Seychelles warblerDavid S Richardson
Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, UK
Proc Biol Sci 272:759-67. 2005..As female choice will result in offspring of higher MHC diversity, MHC-dependent EPP may provide indirect benefits in the Seychelles warbler if survival is positively linked to MHC diversity... - MHC-dependent survival in a wild population: evidence for hidden genetic benefits gained through extra-pair fertilizationsLyanne Brouwer
Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich, UK
Mol Ecol 19:3444-55. 2010..However, such genetic benefits might be hidden and not necessarily apparent in the widely used fitness comparison of extra- and within-pair offspring... - Biogeographical patterns and co-occurrence of pathogenic infection across island populations of Berthelot's pipit (Anthus berthelotii)Lewis G Spurgin
Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich Research Park, Norwich, Norfolk, UK
Oecologia 168:691-701. 2012.... - Comparative analyses of population structure in two subspecies of Nigella degenii: evidence for diversifying selection on pollen-color dimorphismsTove H Jorgensen
Department of Ecology, Section of Plant Ecology and Systematics, Lund University, Sweden
Evolution 60:518-28. 2006..10) significantly exceeded the neutral expectations (estimated from AFLP data), suggesting that local adaptation has played a key role in the evolution of this monogenic character... - Gene conversion rapidly generates major histocompatibility complex diversity in recently founded bird populationsLewis G Spurgin
School of Biological Sciences, University of East Anglia, Norwich Research Park, Norwich NR4 7TJ, UK
Mol Ecol 20:5213-25. 2011..We suggest that the creation of new variants by gene conversion is the predominant mechanism generating MHC variation in genetically depauperate populations, thus allowing them to respond to pathogenic challenges... - MHC heterozygosity and survival in red junglefowlKirsty Worley
School of Biological Sciences, University of East Anglia, Norwich, Norfolk, NR4 7TJ, UK
Mol Ecol 19:3064-75. 2010..This pattern and effect of MHC diversity in our population could reflect the processes ongoing in similarly small, fragmented natural populations... - Population history of Berthelot's pipit: colonization, gene flow and morphological divergence in MacaronesiaJuan Carlos Illera
Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, UK
Mol Ecol 16:4599-612. 2007..The observed genetic and morphological differences may therefore be the result of differing patterns of selection pressures between populations, with Berthelot's pipit undergoing a process of incipient differentiation... - Testosterone, cuckoldry risk and extra-pair opportunities in the Seychelles warblerJanske van de Crommenacker
Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, PO Box 14, 9750 AA Haren, The Netherlands
Proc Biol Sci 271:1023-31. 2004..We conclude that T is involved in sexual courtship displays and mate guarding, but not in gaining EGCs. These findings contrast with those in other species where EGP involves elaborate sexual displays... - Experimental evidence that kin discrimination in the Seychelles warbler is based on association and not on genetic relatednessJan Komdeur
Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, PO Box 14, 9750 AA Haren, The Netherlands
Proc Biol Sci 271:963-9. 2004..Our study provides strong evidence that helping decisions are based on associative-learning cues... - 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... - Avian behaviour: Altruism and infidelity among warblersDavid S Richardson
Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK
Nature 422:580. 2003 - Direct benefits and the evolution of female-biased cooperative breeding in Seychelles warblersDavid S Richardson
Department of Animal and Plant Sciences, University of Sheffield, Sheffield, S10 2TN, United Kingdom
Evolution 56:2313-21. 2002..This may explain why most subordinates in the Seychelles warbler are female...
