mtDna and the islands of the North Atlantic: estimating the proportions of Norse and Gaelic ancestry.
Admixture analyses indicate that the ancestral contributions of mtDNA lineages from Scandinavia to the populations of Iceland, Orkney, the Western Isles, and the Isle of Skye are 37.5%, 35.
Biogeography of the fauna of French Polynesia: diversification within and between a series of hot spot archipelagos
Molecular markers highlight the rapidity of Polynesian human (plus commensal) migrations and the importance of admixture from other populations during the period of prehistoric human voyages.
Wolbachia and other endosymbiont infections in spiders
It is suggested that spiders present a useful opportunity for studying the effect of these sorts of bacteria on the evolution of host traits, such as those that are under sexual selection.

Current genetic drift, even without restrictions to gene flow, may contribute to genetic patchiness on a small scale, although it is likely that conspicuous characteristics such as shell colours and banding patterns are also influenced by selection.
Population structure, history and gene flow in a group of closely related land snails: genetic variation in Partula from the Society Islands of the Pacific
The results suggest that past events as well as ongoing drift and selection may have been important in affecting patterns of variation in Society Island Partula.
Microbial modification of host long-distance dispersal capacity
This novel finding that particular endosymbionts can influence host dispersal is of broad importance given the extremely widespread occurrence of similar bacteria within arthropod communities.
Evolution of spider silks: conservation and diversification of the C‐terminus
Analysis of DNA sequences coding for the C‐terminus of spider silk proteins from a range of spiders suggests that many silk C‐termini share a common origin, and that their physical properties have
Genetic evidence for a family-based Scandinavian settlement of Shetland and Orkney during the Viking periods
An extensive survey of Y-chromosomal and mitochondrial DNA variation in the North Atlantic region suggests that while areas close to Scandinavia, such as Orkney and Shetland, may have been settled primarily by Scandinavian family groups, lone Scandinavian males, who later established families with female subjects from the British Isles, mayHave been prominent in areas more distant from their homeland.
Patterns of genetic variation in Pacific island land snails: the distribution of cytochrome b lineages among Society Island Partula
The distribution of mitochondrial lineages across islands strongly indicates that their origins predate the colonization of the islands in the study, and that they are very unlikely to have evolved entirely in situ.
Molecular evolutionary relationships between partulid land snails of the Pacific
The phylogeny suggests that Samoana has colonized the Pacific from west to east, originating in the area where Eua, believed to be the most ancient partulid genus, is found.
