Última Differences in wing melanization and pigmentation pattern in Drosophila buzzatii (Diptera: Drosophilidae) under chemical stress Rev. Soc. Entomol. Argent. Mongiardino Koch,Nicolás; Hasson,Esteban; Soto,Ignacio M.. Recently, the genetic basis and developmental mechanisms underlying the process of melanization have become progressively elucidated, allowing us to study the evolutionary processes that govern the huge variability of pigmentation observed in nature. However, environmental factors contributing to such variability have received little attention, even though they might have profound ecological consequences. Here we describe a method for analyzing the wing melanization patterns of drosophilids in both qualitative and quantitative ways. We test this method on wings of Drosophila buzzatii Patterson & Wheeler individuals, reared in control and alkaloid-enriched mediums. The alkaloids were extracted from the secondary host of these flies, Echinopsis... Tipo: Info:eu-repo/semantics/article Palavras-chave: Drosophila buzzatii; Melanin; Ecotoxicology; Alkaloids; Stress.

Drosophila serido Vilela & Sene is a polytypic and cactophilic species with broad geographic distribution in Brazil. The morphology of the aedeagi of eight natural populations of D. serido was analyzed. Based on features of their aedeagi, populations of D. serido were discriminated with an efficiency of nearly 75%. The analysis using the Mantel test suggests that the morphological divergence of D. serido is correlated with the geographic distance among populations. There is no single cause to explain the observed pattern; therefore, the results were discussed considering the three main hypotheses to explain the aedeagus evolution: lock and key, pleiotropy and sexual selection. Alternatively, the aedeagus variability of D. serido might be related to... Tipo: Info:eu-repo/semantics/article Palavras-chave: Evolution; Geometric morphometric; Repleta group.
