    Biogeography and evolution of South Pacific topshells (Gastropoda, Trochidae) and their trematode parasites 
    Donald, Kirsten; Kennedy, Martyn; Spencer, Hamish (Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)
    We have used the DNA sequences of Pacific topshells, belonging to the genera Diloma, Melagraphia and Austrocochlea, to ascertain how this group became established over a large area of the Pacific. Phylogenetic analyses of ...

    Does space always matter in the origin of biological species 
    Winter, David J; Spencer, Hamish G (Conference or Workshop Item (Oral presentation), 19th Annual Colloquium of the Spatial Information Research Centre (SIRC 2007: Does Space Matter?), 2007)
    For the last 40 years one of the most contentious issues in evolutionary biology has been determining the role that spatial separation of populations plays in the generation of new species. Most early formulations of this ...

    The effect of spatial population structure on levels of genetic variation 
    Star, Bastiaan; Spencer, Hamish G (Conference or Workshop Item (Oral presentation), 19th Annual Colloquium of the Spatial Information Research Centre (SIRC 2007: Does Space Matter?), 2007)
    A vast amount of genetic variation is a striking hallmark of natural populations, and is vital to the adaptation and long-term survival of a species. Just why this variation is there, however, is unclear: the two most ...

    Phylogeography of carnivorous snails from Northland 
    Spencer, Hamish G; Kennedy, Martyn (Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)
    Landsnails of the subfamily Paryphantinae are active carnivores on earthworms and other snails. Most species are endemic to Northland, New Zealand, are several are of conservation concern, being threatened by habitat ...

    Using molecular genetics to gain insight into allopatric and sympatric speciation of topshells and their parasitic trematodes 
    Donald, Kirsten; Spencer, Hamish (Conference or Workshop Item (Paper), 15th Annual Colloquium of the Spatial Information Research Centre (SIRC 2003: Land, Place and Space), 2003)
    Prevailing theory suggests that many parasite species have evolved in tight congruence with their hosts, with the parasite phylogeny mirroring that of the host. This theory is based largely on studies of host-parasite ...
