Data from: Genetic consequences of a century of protection: serial founder events and survival of the little spotted kiwi (Apteryx owenii)

Kristina M. Ramstad, Rogan M. Colbourne, Hugh A. Robertson, Fred W. Allendorf & Charles H. Daugherty
We present the outcome of a century of post-bottleneck isolation of a long-lived species, the little spotted kiwi (Apteryx owenii, LSK) and demonstrate that profound genetic consequences can result from protecting few individuals in isolation. LSK were saved from extinction by translocation of five birds from South Island, New Zealand to Kapiti Island 100 years ago. The Kapiti population now numbers some 1200 birds and provides founders for new populations. We used 15 microsatellite loci...

Data from: Severe inbreeding depression and no evidence of purging in an extremely inbred wild species - the Chatham Island black robin

Euan S. Kennedy, Catherine E. Grueber, Richard P. Duncan & Ian G. Jamieson
Although evidence of inbreeding depression in wild populations is well established, the impact of genetic purging in the wild remains controversial. The contrasting effects of inbreeding depression, fixation of deleterious alleles by genetic drift and the purging of deleterious alleles via natural selection mean that predicting fitness outcomes in populations subjected to prolonged bottlenecks is not straightforward. We report results from a long-term pedigree study of arguably the world's most inbred wild species of bird:...

Data from: Extensive variation at MHC DRB in the New Zealand sea lion (Phocarctos hookeri) provides evidence for balancing selection

Marine mammals are often reported to possess reduced variation of major histocompatibility complex (MHC) genes compared with their terrestrial counterparts. We evaluated diversity at two MHC class II B genes, DQB and DRB, in the New Zealand sea lion (Phocarctos hookeri, NZSL) a species that has suffered high mortality owing to bacterial epizootics, using Sanger sequencing and haplotype reconstruction, together with next-generation sequencing. Despite this species’ prolonged history of small population size and highly restricted...
