“…Strong evidence for speciation having occurred within an island or archipelago is provided by the monophyly of species endemic to that region. Accordingly, for example, it appears that 150 species of diving beetle are the product of a single colonisation event followed by speciation within the island of New Guinea (Balke et al 2007), and 1000 species of picture-winged Drosophila are the product of speciation within the Hawaiian archipelago (O'Grady et al 2011). Islands have illustrated that the factors that interact to provide conditions necessary for in situ speciation include isolation (Manceau et al 2010), age (Gillespie & Baldwin 2010) and area (Losos & Schluter 2000;Kisel & Barraclough 2010) of the region concerned, and variables often associated with area, such as topographic complexity and elevation (Whittaker et al 2008).…”

Islands as model systems in ecology and evolution: prospects fifty years after MacArthur‐Wilson

et al. 2015

The study of islands as model systems has played an important role in the development of evolutionary and ecological theory. The 50th anniversary of MacArthur and Wilson's (December 1963) article, 'An equilibrium theory of insular zoogeography', was a recent milestone for this theme. Since 1963, island systems have provided new insights into the formation of ecological communities. Here, building on such developments, we highlight prospects for research on islands to improve our understanding of the ecology and evolution of communities in general. Throughout, we emphasise how attributes of islands combine to provide unusual research opportunities, the implications of which stretch far beyond islands. Molecular tools and increasing data acquisition now permit reassessment of some fundamental issues that interested MacArthur and Wilson. These include the formation of ecological networks, species abundance distributions, and the contribution of evolution to community assembly. We also extend our prospects to other fields of ecology and evolution -understanding ecosystem functioning, speciation and diversification -frequently employing assets of oceanic islands in inferring the geographic area within which evolution has occurred, and potential barriers to gene flow. Although island-based theory is continually being enriched, incorporating non-equilibrium dynamics is identified as a major challenge for the future.

“…Second, some such radiations also contain sympatric or closely occurring sister species endemic to the same island (e.g. Hawaiian Tetragnatha and Drosophila: Gillespie & Baldwin 2010;O'Grady et al 2011). These have high potential to have diverged in the presence of intermittent or ongoing gene flow.…”

“…The Hawaiian Drosophilidae as a whole have been the target of a number of studies (e.g. O' Grady and DeSalle, 2008;O'Grady et al, 2011;Thomas and Hunt, 1993;Throckmorton, 1966), but only one (Kambysellis et al, 1995) has specifically focused on the picture wing clade in its entirety. The latter is useful as a general outline, but suffers from weak sampling within the large grimshawi group, absence of any nudidrosophila species, and few outgroup taxa.…”

“…Here we analyze the differential gene expression and allelespecific expression (ASE) of testis-level fertility in BC males between two closely related endemic Hawaiian Drosophila species in the picture-wing clade under planitibia group and IVβ subgroup, Drosophila planitibia and Drosophila silvestris (Spieth, 1986). D. silvestris is endemic to Hawai'i Island and D. planitibia is endemic to the island of Maui, and diverged ∼ 0.7 Mya (O'Grady et al, 2011;Magnacca and Price, 2015). Both species are bark breeders, whereby females oviposit eggs on and larvae develop in the decaying bark of the endemic Hawaiian flowering plant, Clermontia spp.…”

Hybrid sterility and evolution in Hawaiian Drosophila: differential gene and allele-specific expression analysis of backcross males

et al. 2016

The Hawaiian Drosophila are an iconic example of sequential colonization, adaptive radiation and speciation on islands. Genetic and phenotypic analysis of closely related species pairs that exhibit incomplete reproductive isolation can provide insights into the mechanisms of speciation. Drosophila silvestris from Hawai'i Island and Drosophila planitibia from Maui are two closely related allopatric Hawaiian picture-winged Drosophila that produce sterile F 1 males but fertile F 1 females, a pattern consistent with Haldane's rule. Backcrossing F 1 hybrid females between these two species to parental species gives rise to recombinant males with three distinct sperm phenotypes despite a similar genomic background: motile sperm, no sperm (sterile), and immotile sperm. We found that these three reproductive morphologies of backcross hybrid males produce divergent gene expression profiles in testes, as measured with RNA sequencing. There were a total of 71 genes significantly differentially expressed between backcross males with no sperm compared with those backcross males with motile sperm and immotile sperm, but no significant differential gene expression between backcross males with motile sperm and backcross males with immotile sperm. All of these genes were underexpressed in males with no sperm, including a number of genes with previously known activities in adult testis. An allele-specific expression analysis showed overwhelmingly more cis-divergent than transdivergent genes, with no significant difference in the ratio of cis-and trans-divergent genes among the sperm phenotypes. Overall, the results indicate that the regulation of gene expression involved in sperm production likely diverged relatively rapidly between these two closely related species.
