“…For example, if two species have a close ecological relationship, such as a predator–prey relationship, symbiotic contact, the sharing of parasites, or even the use of the same natural resources, the chances that an HTT event will occur between these species increases (Houck et al 1991; Yoshiyama et al 2001; Loreto et al 2008; Gilbert et al 2010; Schaack et al 2010). This scenario has been used to explain cases of HTT among sympatric crustaceans (Casse et al 2006) and in Drosophila species (Mota et al 2010; Carareto et al 2011). …”

The genetic similarity observed among species is normally attributed to the existence of a common ancestor. However, a growing body of evidence suggests that the exchange of genetic material is not limited to the transfer from parent to offspring but can also occur through horizontal transfer (HT). Transposable elements (TEs) are DNA fragments with an innate propensity for HT; they are mobile and possess parasitic characteristics that allow them to exist and proliferate within host genomes. However, horizontal transposon transfer (HTT) is not easily detected, primarily because the complex TE life cycle can generate phylogenetic patterns similar to those expected for HTT events. The increasingly large number of new genome projects, in all branches of life, has provided an unprecedented opportunity to evaluate the TE content and HTT events in these species, although a standardized method of HTT detection is required before trends in the HTT rates can be evaluated in a wide range of eukaryotic taxa and predictions about these events can be made. Thus, we propose a straightforward hypothesis test that can be used by TE specialists and nonspecialists alike to discriminate between HTT events and natural TE life cycle patterns. We also discuss several plausible explanations and predictions for the distribution and frequency of HTT and for the inherent biases of HTT detection. Finally, we discuss some of the methodological concerns for HTT detection that may result in the underestimation and overestimation of HTT rates during eukaryotic genome evolution.

Zaprionus indianus is a dipteran (Drosophilidae) with a wide distribution throughout the tropics and temperate Palearctic and Nearctic regions. There have been proposals to reclassify the genus Zaprionus as a subgenus or group of the genus Drosophila because various molecular markers have indicated a close relationship between Zaprionus species and the immigrans-Hirtodrosophila radiation within Drosophila. These markers, together with alloenzymes and quantitative traits, have been used to describe the probable scenario for the expansion of Zaprionus indianus from its center of dispersal (Africa) to regions of Asia (ancient dispersal) and the Americas (recent dispersal). The introduction of Z. indianus into Brazil was first reported in 1999 and the current consensus is that the introduced flies came from high-latitude African populations through the importation of fruit. Once in Brazil, Z. indianus spread rapidly throughout the Southeast and then to the rest of the country, in association with highway-based fruit commerce. These and other aspects of the evolutionary biology of Z. indianus are addressed in this review, including a description of a probable route for this species’ dispersal during its recent expansion.

“…Due to its evolutionary history, ecological and morphological diversity, the Zaprionus genus seems to be a good model for comparative studies with the melanogaster subgroup. The similarities between species of the genus Zaprionus and species of the subgroup melanogaster in terms of their evolutionary characteristics and their ecological diversity have been highlighted in evolutionary studies (De Setta et al, 2009;2011). Although the phylogenetic relationships within the Zaprionus genus had been recently proposed (Yassin et al, 2008), its taxonomic positioning in the Drosophilidae family remains a matter for discussion.…”

“…In addition to their shared ecological characteristics, the historic and contemporary geographic coexistence between species of the subgroup melanogaster and the subgenus Zaprionus suggest that these two groups of species passed through a period that allowed the transfer of transposable elements during their diversification. The invasive potential of various species of both genus, such as D. melanogaster (David and Capy, 1988), D. simulans (Hamblin and Veuille, 1999) and Z. indianus (Gupta, 1970) may have promoted horizontal transfer events (Carareto, 2011).…”
