Data from: Genetic history of a colonising population: Drosophila buzzatii (Diptera: Drosophilidae) in Australia
Drosophila buzzatii Patterson & Wheeler, a cactophilic species that feeds and breeds in the rotting tissues of various Opuntia cactus species, was inadvertently introduced to Australia from Argentina sometime during the period 1931–1936. After a bottleneck at introduction, its spread through the cactus distribution was probably very rapid as a result of natural dispersal from the site of introduction and from three other foci colonized from the introduction site by human intervention. By 1940, the Opuntia distribution and consequently that of D. buzzatii was reduced to spatially isolated populations, with probable further bottlenecking of at least some of the D. buzzatii populations. Allozyme data (primarily six polymorphic loci) from flies collected during April 1972 to February 1996 at 67 localities were used to examine current population differentiation and relationships, as well as to infer aspects of their demographic history. Although there is significant isolation-by-distance, genetic relationships among the populations are not simply related to geographical distance, implying that genetic drift has contributed to population differentiation. However, the biotic and, to an extent, the physical environment are not the same in Australia as in Argentina. Consequently, exposure to novel environments has led to local adaptation and further population differentiation. Genetic variation and the structure of Australian populations apparently are determined by founder effects (drift) at the level of individual breeding sites (cactus rots), by diversifying selection among rots within a locality, as well as by drift and geographically varying selection among localities.
FIGURE 1 in The placement of Engiscaptomyza, Grimshawomyia, and Titanochaeta, three clades of endemic Hawaiian Drosophilidae (Diptera)
FIGURE 1. Phylogenetic relationships of the Hawaiian Drosophilidae (after Bonacum 2001), with particular emphasis on the genus Scaptomyza and associated groups (Titanochaeta, Grimshawomyia, and Engiscaptomyza). Numbers above the line at each node are bootstrap proportions, numbers below the line are decay indices (after Bonacum 2001; see text for details). Numbers of species sampled/total species described in a group is tabulated individually for the Hawaiian Drosophila lineages, as well as for the Hawaiian Drosophila and genus Scaptomyza as a whole (numbers are not additive due to species unplaced in described groups). Chromosome numbers for the ancestor of the Hawaiian Drosophilidae (N=6) and groups where two independent fusions are inferred (modified mouthpart group and genus Scaptomyza) are mapped on the tree, after (Clayton et al. 1972; Yoon et al. 1975).
