Radiation of the ,,Drosophila“ subgenus (Drosophilidae, Diptera) in the Neotropics
Journal of Zoological Systematics and Evolutionary Research, 2010 We present a phylogenetic hypothesis for 72 ,,Drosophila“ species, constructed through analysis from the paralogous alpha methyldopa (amd) and dopa decarboxylase (ddc) nuclear genes (encompassing a total of 2015 base pairs). Our data support the subdivision of the paraphyletic subgenus ,,Drosophila“ into three main radiations (the immigrans-tripunctata,

New records of six species of subgenus Sophophora (Drosophila, Drosophilidae) collected in Brazil
Zootaxa, 2004 The Drosophilidae Family of flies is cosmopolitan and is distributed in many types of ecosystems. The knowledge about the distribution of these species in Brazil has grown since the 1940s. However, the large extension of the Brazilian territory and the complexity of its ecosystems accounts for the fact of that this research field is still ...

Historical patterns of niche dynamics in Neotropical species of the Drosophila subgenus (Drosophilidae, Diptera) [PDF]
Evolutionary Ecology, 2015 Niche conservatism (NC) presence is a controversial question in evolutionary ecology. In Drosophila, little is known about which is the preponderant evolutionary pattern, since the adaptive radiation hypothesis first proposed by Throckmorton assumed niche divergence (ND) according to a niche occupancy scenario. Nevertheless, this hypothesis has not yet

Sex-specific methylation in Drosophila: an investigation of the Sophophora subgenus
Genetica, 2010Epigenetic phenomena have been widely characterized in the genomes of vertebrates and DNA methylation is a key mechanism of epigenetic regulation. The DNA methylation systems of invertebrates and vertebrates show several notable differences. However, the evolutionary implications of those differences only recently began to be revealed.

Chromosoma, 1999 The successful hybridization of cosmid clones from Drosophila melanogaster (Sophophora subgenus) to the salivary gland chromosomes of other species as distantly related as those in the Drosophila subgenus attests their great potential for unravelling genome evolution. We have carried out, using 28 cosmids and 13 gene clones, a study of the organization

Chromosome research : an international journal on the molecular, supramolecular and evolutionary aspects of chromosome biology, 2000 The molecular organization of a 1.944-Mb chromosomal region of Drosophila melanogaster around the Adh locus has been analyzed in two repleta group species: D. repleta and D. buzzatii. The extensive genetic and molecular information about this region in D.

Esterases are known for their involvement in several physiological processes and high degree of polymorphism, in many organisms. Such polymorphism has been used to characterize species and species groups and to study genetic changes occurred in their evolutionary history.
