“…These four new species (D. koepferae, D. seriema, D. gouveai and D. antonietae) with D. serido and D. borborema, previously described, came to be the 'D. serido sibling set' (Tidon-Sklorz & Sene, 2001), replacing the designation of 'Drosophila serido superespecie taxon' proposed by because this species group does not fit the definition of 'superespecie' according to Mayr (1963). Thus, the D. buzzatii cluster is composed of the D. buzzatii and the six species of the 'Drosophila serido sibling set'.…”

“…The Drosophila buzzatii cluster (repleta group, Drosophila genus) is today composed of seven nominal species: D. buzzatii (Patterson & Wheeler, 1942), D. serido (Vilela & Sene, 1977), D. antonietae (Tidon-Sklorz & Sene, 2001), D. seriema (TidonSklorz & Sene, 1995a), D. gouveai (Tidon-Sklorz & Sene, 2001), D. borborema (Vilela & Sene, 1977) and D. koepferae . With the exception of D. buzzatii, which was introduced to other continents along with the Opuntia ficus-indica, one of its host cacti (Barker et al, 1985), all of these species are endemic to South America (Figure 1).…”

The Drosophila buzzatii cluster is composed of seven cactophilic species and their known geographical distribution encompasses the open vegetation diagonal, which includes the morphoclimatic Domains of the Caatinga, Chaco and Cerrado, which are situated between the Amazon and the Atlantic forests. Besides these areas, these cactophilic species are also found in a narrow strip along the Atlantic coast from northeastern Brazil to the southern tip of the country. The hypothesis of vicariant events, defining the core areas of each species, is proposed to explain the historical diversification for the cluster. The intraspecific analysis for the cluster shows a population structure with gene flow restricted by distance, range expansion with secondary contact resulting in introgression and simpatry, especially in the limits of the species distribution, polytypic populations and assortative mating in inter population experiments. There is a variation related to these events that depends on the species and geographic origin of the population analyzed. These events are, hypothetically, described as the results of expansion and retraction of the population ranges, as a consequence of their association with cacti, which theoretically follow the expansion and retraction of dry areas during the paleoclimatic oscillations in South America, as that promoted by the glacial cycles of the Quaternary. The Drosophila buzzatii cluster is divided into two groups. The first one is composed of D. buzzatii, a species that has a broad geographic distribution and no significant differentiation between its populations. The second is the Drosophila serido sibling set, which encompasses the others species and is characterized by a significant potential for differentiation.

“…Drosophila antonietae was expected to be collected in all areas, as it is a cactophilic species that occurs in the south and southeast regions of Brazil, and north of the eastern boundary of the argentinean chaco. This species always occurs associated with the columnar cactus Cereus hildmaniannus in the xerophytic vegetation of gallery and mesophytic forests in the valleys of the paraná-uruguai river basin (Tidon-sklorz & sene, 2001). This pattern of distribution that isolates Drosophila antonietae from other D. buzzatii cluster species coincides with defined patterns of other dipterans and also with regions of endemism, suggesting vicariant events such as zoogeographic barriers established in earlier geological eras or climatic events that prevented gene flow enabling the accumulation of differences between populations (amorin & pires, 1996).…”

The Drosophila community in xerophytic vegetations of the upper Parana-Paraguay river basin

The genus Drosophila is the most abundant in the Drosophilidae family. some species are endemic to certain regions and others are cosmopolitans. in Brazil, there are several ecosystems to explore regarding the composition and ecological aspects of Drosophila. xerophytic areas are an example. They can be found in the south and southeast of Brazil as islands, a result of paleoclimatic cycle changes. The aim of the present work is to provide information about the composition of the Drosophila community in eight xerophytic areas (where the cactus Cereus hildmaniannus occurs) in the south and southeast of Brazil. This work is an important step in the study of quantitative ecological aspects of the Drosophila community in xerophytic areas that form continental islands in the neotropical region. The composition of the Drosophila community which was found is compatible with previous work in several aspects. The ecological indexes showed a possible positive association between diversity and the degree of preservation of the studied areas. são paulo state communities presented the highest similarity among the sites tested, although no statistical significant correlation between the Jaccard index and geographical distance was found using the mantel test.

“…Currently, the D. buzzatii cluster is composed of seven nominal Drosophila species (D. antonietae, D. borborema, D. buzzatii, D. gouveai, D. koepferae, D. serido and D. seriema). According to aedeagus and wing morphology, the D. buzzatii cluster can be divided into two species groups (Tidon-Sklorz and Sene, 2001;Moraes et al, 2004). One of them is composed by D. buzzatii populations, and another group, called the D. serido sibling set, is composed by the remaining D. buzzatii cluster species.…”

Molecular characterization of SSS139, a new satellite DNA family in sibling species of the Drosophila buzzatii cluster

We characterized sequences of a novel SSS139 RsaI satellite DNA family in Drosophila gouveai and Drosophila seriema, two members of the Drosophila buzzatii cluster (D. repleta group). The sequences were AT-rich (69%) with a monomer unit length of about 139 bp and contained two direct subrepeats of 14 bp and 16 bp, suggesting that it might have originated by the duplication of smaller sequences. Southern and dot-blot hybridization analyses also detected SSS139 in other Drosophila buzzatii cluster species (D. koepferae, D. antonietae, D. borborema and D. serido) but not in D. buzzatii. These results agree with the marginal phylogenetic position of D. buzzatii within the D. buzzatii cluster.Key words: Drosophila buzzatii cluster, molecular evolution, repetitive DNA, satellite DNA, SSS139 satellite DNA. Satellite DNA consists of highly repetitive and tandemly arranged DNA sequences (Charlesworth et al., 1994) which are considered the main components of constitutive heterochromatin and are usually located in the centromeric regions of chromosomes and, less frequently, in telomeres (Charlesworth et al., 1994;Ugarkovic and Plohl, 2002). Satellite DNAs are heterogeneous and no general function has been attributed to this DNA class. However, despite the terminology "junk DNA" frequently associated with these sequences (Orgel and Crick, 1980), several biological roles have been suggested for some satellite DNA families, such as regulation of both heterochromatin condensation and genetic expression (reviewed by Ugarkovic, 2005). Moreover, satellite DNAs are involved in the maintenance of functional centromeres in mammals (Willard, 1990) and might also be related to the late replication of centromeres (Csink and Henikoff, 1998).The satellite DNA sequences evolve in a concerted manner (Dover, 1982) and the main molecular mechanisms involved in its evolution are slippage replication, unequal crossing-over, gene conversion and rolling circle replication, which can, in general, induce a strong intra-specific homogenization of satellite DNA sequences and interspecific divergence (Dover, 1982;Charlesworth et al., 1994).The monomers of a satellite DNA can be speciesspecific (Bachmann et al., 1994;Abadon et al., 1998) or shared among phylogenetically related species (Watabe et al., 1997;Lopez-Flores et al., 2004;Kuhn and Sene, 2005). Though there are examples of extremely conserved satellite DNA sequences among species that diverged for long evolutionary periods (de la Herrán et al., 2001;Mravinac et al. 2002), most satellite DNA shared among species presents high evolutionary rates, acquiring diagnostic mutations for each species.The Drosophila buzzatii cluster (D. repleta group, D. buzzatii complex) is a monophyletic group composed by cactophilic and sibling species that are naturally endemic to South America . Currently, the D. buzzatii cluster is composed of seven nominal Drosophila species (D. antonietae, D. borborema, D. buzzatii, D. gouveai, D. koepferae, D. serido and D. seriema).
