Resumo: | Drosophila maculifrons belongs to the guaramunu group and in habits forests in Brazil. It can be found mainly in the Atlantic Forest domains of the south, southeast and central-west regions. On the other hand, D. ornatifrons belongs to the guarani group and has been collected all over Brazil, but in small number sample. In spite of the great amount of cytogenetics and molecular data for these species (mainly related to phylogenetic analyses), there is no comparative study using morphological characters in natural populations. Thus, in order to quantify and identify some patterns of morphological variation in populations of these species, this work aimed to analyze the aedeagus and wing morphology in seven populations of D. maculifrons and four populations of D. ornatifrons using geometric morphometry of samples collected in areas of ombrophylous mixed forest and semideciduous seasonal forest. Our results showed that there was statistically significant variation for wing size and shape among the populations for both species. Drosophila ornatifrons populations had greater Procrustes distance among each other than the distances among D. maculifrons populations. This variation in the wing morphology detected among populations of both species could be related to their ecological features. It is possible that D. ornatifrons have a narrower ecological specificity, which hinder its occurrence and capture, and D. maculifrons is probably more generalist and, therefore, suffer less environmental pressure when compared to D. ornatifrons. Regarding the aedeagus, there was no morphological differentiation for shape in D. ornatifrons, while in D. maculifrons it was detected statistically significant differences among sampled populations, mainly between those located in the south against those from the southeast regions of Brazil. The differences detected for these two morphological markers in the patterns of variation corroborated that the differentiation in the genital characters is not always followed by similar differentiation in the morphology of the rest of the body. Despite wing and aedeagus of D. maculifrons and D. ornatifrons have depicted different results in the populational analyses, the evolution and morphological divergence among populations of these species seems to be linked to differential niche exploitation and/or to differences in the temperature in the sampled localities |

Já D. ornatifrons pertence ao grupo guarani e tem sido encontrada em todas as regiões do Brasil, porém em pequeno número amostral. Apesar da grande quantidade de dados citogenéticos e moleculares para estas espécies (principalmente relacionados a análises filogenéticas), não existe nenhum estudo comparativo entre características morfológicas utilizando populações naturais. Assim, para quantificar a diferenciação e identificar alguns padrões populacionais de variação morfológica nestas espécies, este trabalho teve como objetivo analisar a morfologia do edeago e das asas de sete populações de D. maculifrons e quatro populações de D. ornatifrons por meio da morfometria geométrica de amostras coletadas em áreas de floresta ombrófila mista e floresta estacional semidecidual. Os resultados mostraram que houve diferenciação significativa para o tamanho e a forma das asas entre as populações para as duas espécies. As populações de D. ornatifrons apresentaram maior distância de Procrustes entre si do que as de D. maculifrons. Esta variação pode estar relacionada com aspectos ecológicos das mesmas, com D. ornatifrons possuindo uma maior especificidade ecológica, o que dificulta a sua ocorrência e captura, e D. maculifrons sendo mais generalista e sendo, portanto, mais facilmente encontrada quando comparada com D. ornatifrons. Para o edeago não houve diferenciação morfológica significativa para a forma em D. ornatifrons. Em D. maculifrons foram observadas diferenças significativas para a forma do edeago entre as populações amostradas, principalmente entre as localizadas no sul e sudeste do Brasil. Estas diferenças observadas para os dois marcadores morfológicos corroboram que a diferenciação nos caracteres da genitália masculina sofrida pelos indivíduos nem sempre é acompanhada por igual diferenciação na morfologia do restante do corpo. Apesar da asa e do edeago terem apresentados resultados diferentes quanto ao padrão de diferenciação interpopulacional para as duas espécies, a evolução e a divergência morfológica entre as populações de D. ornatifrons e de D. maculifrons parecem estar ligadas provavelmente a exploração diferencial de nichos por estas espécies e/ou relacionadas a diferença de temperatura entre os locais de coleta.Made available in DSpace on 2016-09-20T12:29:27Z (GMT).
