Study of four Neotropical species of tree crickets Oecanthus Serville, 1831 (Orthoptera, Gryllidae) using cytogenetic and molecular markers
Silva, Anelise Fernandes e; Oliveira, Thays Duarte de; Bertocchi, Natasha Ávila; Gaiesky, Vera Lúcia da Silva Valente; Zefa, Edison; Deprá, Maríndia (2022) [Artigo de periódico]Karyotypes in the worldwide subfamily Oecanthinae show variations in diploid number, chromosome morphology, and sex-chromosome system. This study described the chromosome set and phylogenetic relationships of four Neotropical ... -
Temperature-dependent gonadal hybrid dysgenesis in Drosophila willistoni
Regner, Luciana Pereira; Abdelhay, Eliana Saul Furkim Werneck; Rohde, Claudia; Rodrigues, Jaqueline Josi Sama; Gaiesky, Vera Lúcia da Silva Valente (1999) [Artigo de periódico]Temperature-dependent gonadal dysgenesis was shown to occur in the progeny of both inter- and intrastrain crosses involving two populations of Drosophila willistoni, one of which was an old laboratory stock, and the other, ... -
Temperature, urbanization and body color polymorphism in south brazilian populations of Drosophila kikkawai (Diptera, Drosophilidae)
Costa, Bartira Ercília Pinheiro da; Rohde, Claudia; Gaiesky, Vera Lúcia da Silva Valente (2003) [Artigo de periódico]Body color polymorphism of urban populations of cosmopolite fly Drosophila kikkawai Burla, 1954 was investigated in relation to its possible association with environmental temperature. Samples of D. kikkawai were collected ... -
The drosophilid fauna (Diptera, Drosophilidae) of the transition between the Pampa and Atlantic Forest Biomes in the state of Rio Grande do Sul, southern Brazil : first records
Hochmüller, Cleverton Juliano Cardoso; Silva, Marcelo Lopes da; Gaiesky, Vera Lúcia da Silva Valente; Schmitz, Hermes José (2010) [Artigo de periódico]Embora os trabalhos com assembléias de drosofilídeos (Diptera, Drosophilidae) tenham se tornado relativamente abundantes nas últimas décadas, ainda existem ambientes a serem explorados. O presente trabalho buscou observar ... -
The flower flies and the unknown diversity of Drosophilidae (Diptera): a biodiversity inventory in the Brazilian fauna
Schmitz, Hermes José; Gaiesky, Vera Lúcia da Silva Valente (2019) [Artigo de periódico]Diptera is a megadiverse order, reaching its peak of diversity in Neotropics, although our knowledge of dipteran fauna from this region is grossly lacking. This applies even to the most studied families, such as Drosophilidae. ... -
Three decades of studies on chromosomal polymorphism of Drosophila willistoni and description of fifty different rearrangements
Rhode, Cláudia; Gaiesky, Vera Lúcia da Silva Valente (2012) [Artigo de periódico]Drosophila willistoni (Insecta, Diptera) is considered a paradigm for evolutionary studies. Their chromosomes are characterized by multiple paracentric inversions that make it hard to identify and describe chromosomal ... -
Transposable elements P and gypsy in natural populations of Drosophila willistoni
Sassi, Adriana Koslovski; Heredia, Fabiana de Oliveira; Loreto, Élgion Lúcio da Silva; Gaiesky, Vera Lúcia da Silva Valente; Rohde, Claudia (2005) [Artigo de periódico]The presence and integrity of the P transposon and the gypsy retrotransposon in the genome of 18 samples of natural Drosophila willistoni populations collected from a large area of South America were Southern blot screened ... -
Two decades of colonization of the urban environment of Porto Alegre, southern Brazil, by Drosophila paulistorum (Diptera, Drosophilidae)
Garcia, Ana Cristina Lauer; Valiati, Victor Hugo; Gottschalk, Marco Silva; Rohde, Claudia; Gaiesky, Vera Lúcia da Silva Valente (2008) [Artigo de periódico]Drosophila paulistorum Dobzhansky & Pavan, 1949 era considerada inicialmente ausente em ambientes com influência antrópica, mas a detecção dessa espécie na cidade de Porto Alegre, sul do Brasil, em 1985, sugeriu seu potencial ...
