Disease ecology in the Galápagos Hawk (Buteo galapagoensis): host genetic diversity, parasite load and natural antibodies
An increased susceptibility to disease is one hypothesis explaining how inbreeding hastens extinction in island endemics and threatened species. Experimental studies show that disease resistanceExpand

Extensive MHC class II B gene duplication in a passerine, the common Yellowthroat (Geothlypis trichas).
The major histocompatibility complex (MHC) is characterized by a birth and death model of evolution involving gene duplication, diversification, loss of function, and deletion. As a result, geneExpand

Phylogeography of the Galápagos hawk (Buteo galapagoensis): a recent arrival to the Galápagos Islands.
Galápagos hawks (Buteo galapagoensis) are one of the most inbred bird species in the world, living in small, isolated island populations. We used mitochondrial sequence and nuclear minisatellite dataExpand

Rapid loss of MHC class II variation in a bottlenecked population is explained by drift and loss of copy number variation
Population bottlenecks may reduce genetic variation and potentially increase the risk of extinction. Here, we present the first study to use historic samples to analyse loss of variation at the majorExpand

Low MHC variation in the endangered Galápagos penguin (Spheniscus mendiculus)
The major histocompatibility complex (MHC) is one of the most polymorphic regions of the genome, likely due to balancing selection acting to maintain alleles over time. Lack of MHC variability hasExpand

Mhc class II diversity and balancing selection in greater prairie-chickens
The major histocompatibility complex (Mhc) of domestic chickens has been characterized as small and relatively simple compared with that of mammals. However, there is growing evidence that the Mhc ofExpand

Multiple Paternity in Loggerhead Turtle Clutches
Microsatellite DNA was used to determine paternity in loggerhead turtle clutches. Hatchlings from three clutches were genotyped at two loci, as were their mothers and a sample of adults. AExpand

MHC VARIATION IS RELATED TO A SEXUALLY SELECTED ORNAMENT, SURVIVAL, AND PARASITE RESISTANCE IN COMMON YELLOWTHROATS
Hamilton and Zuk proposed that females choose mates based on ornaments whose expression is dependent on their genetically based resistance to parasites. The major histocompatibility complex (MHC)Expand

Differentiation with drift: a spatio-temporal genetic analysis of Galápagos mockingbird populations (Mimus spp.)
Small and isolated island populations provide ideal systems to study the effects of limited population size, genetic drift and gene flow on genetic diversity. We assessed genetic diversity within andExpand

Drift and selection influence geographic variation at immune loci of prairie‐chickens
Previous studies of immunity in wild populations have focused primarily on genes of the major histocompatibility complex (MHC); however, studies of model species have identified additionalExpand
