Cryptic Subspeciation in Drosophila Belonging to the Subgenus Sophophora
The American Naturalist, 1954A new subspecies, Drosophila tropicalis cubana, belonging to the siblings of the willistoni group of the subgenus Sophophora and distributed throughout the Greater Antilles is described and compared with the South American subspecies, Drosophila tropicalis tropicalis Burla and da Cunha.

New records of six species of subgenus Sophophora (Drosophila, Drosophilidae) collected in Brazil
Zootaxa, 2004The 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 ...

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

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.

RNA sequencing has been used to assess the relationships among species of the subgenus Sophophora of the genus Drosophila. Two divergent domains, D1 and D2, of the large ribosomal RNA (28S), totalling 550 nucleotides have been sequenced using the rRNA direct sequencing method.

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.

The American Naturalist, 1963
Sexual isolation was found to be weak in four members of the victoria group, three of which are isolated by hybrid mortality. The difference in mating success between D. l. lebanonensis and D. l. casteeli, which are widely separated geographically, is mainly one of propensity; the reciprocal heterogamic matings between these subspecies resulting in a ...

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

Nature, 1985
The biological properties of the P element of Drosophila melanogaster differ from those of other mobile elements in this genus in that its mobility is associated with dysgenic traits that might be expected to limit its distribution or spread1. The P element is widely distributed among natural populations of D.
