“…According to Avise & Smith (1997) and Thorpe (1983), populations of the same species tend to show Nei's identity above 0.9 and distance below 0.1, and congeneric species show identity between 0.25 and 0.85 and distances between 0.16 and 1.39. Similar results were found by Mateus et al (2010) There are several reasons that could explain the results obtained so far for D. ornatifrons. The characteristics of each collection area, such as type of vegetation, climate, altitude and mainly the conservation status.…”

Similar results were found by Mateus et al (2010) in two criptic species of the buzzatii cluster: D. antonietae and D. gouveai. In fact, a recent aedeagi analysis of flies identifed as D. ornatifrons resulted in at least three different aedagi present in the sample (N. P. Heinz, personal communication).…”

He attended the University of Leeds Department of Genetics in England for his PhD study, focusing on analysis of germin gene products. After he received his PhD degree, he was appointed as Assistant Professor at Mustafa Kemal University, Hatay. In 2000 he obtained the title of Associate Professor in genetics from the Turkish High Education Council. Following five years of extensive research and lecturing he was appointed as Professor of Molecular Biology in 2006. Prof. Çalışkan was awarded for his postdoctoral research in England withgrants from NATO and University. In addition to acting as a reviewer and advisor to numerous journals and grant awarding institutions, he has been involved in the establishment of the Biology Department at Mustafa Kemal University.

“…Eight isofemale lines (four of each species) of D. antonietae and D. gouveai were available as laboratory stocks at the onset of the experiments. They were originally founded with wild inseminated females collected in nature from populations sampled in and out the parapatric corridor (Figure 1; see details of the sites of collection and further information about the natural populations in Soto et al., 2007; Mateus et al., 2010).…”

The Drosophila repleta group encompasses an ensemble of species that inhabit desertic areas that are inhospitable to other drosophilids. These species have a tractable ecology, as they breed and feed on necrotic tissues of a wide diversity of species of Cactaceae, with a certain degree of host specificity, which makes them suitable models to investigate the role of host plant shifts in diversification. Most species have their own primary host plant, which may be shared with a closely related species. However, the consequences of host plant shifts from primary to secondary hosts have not been thoroughly studied so far. We investigated the effects of the cactus host on developmental instability and performance of D. gouveai Tidon‐Sklorz & Sene and D. antonietae Tidon‐Sklorz & Sene (Diptera: Drosophilidae), a pair of closely related sibling species, and of their F1 interspecific hybrids reared in primary and secondary host plants. Fluctuating asymmetry (FA) for wing size was significantly greater in flies of both species reared in their respective secondary cactus host than in those grown in the primary host. Interspecific hybrids also exhibited host‐dependent levels of FA. However, hybrids did not show greater FA than the parental species, suggesting that hybridization per se did not affect developmental stability. Even though cactus host shifts affected different measures of fitness (larval viability and adult size) both in D. antonietae and D. gouveai, we did not detect a consistent relationship between FA and fitness. Our results suggest that FA cannot be used as a sensitive indicator of genetic and phenotypic quality and we discuss its application as a fitness predictor.
