Host-related life history traits in interspecific hybrids of cactophilic Drosophila

Mostrar todas las versiones(2)

In the genus Drosophila (Diptera: Drosophilidae), interspecific hybridization is a rare phenomenon. However, recent evidence suggests a certain degree of introgression between the cactophilic siblings Drosophila buzzatii Patterson & Wheeler and Drosophila koepferae Fontdevila & Wasserman. In...

Cactus Developmental time Diptera Drosophilidae Fitness Host plant Phenotypic plasticity Viability fitness fly host plant hybrid interspecific interaction introgression life history phenotypic plasticity Cactaceae Diptera Drosophila buzzatii Drosophila koepferae Drosophilidae In the genus Drosophila (Diptera: Drosophilidae), interspecific hybridization is a rare phenomenon. However, recent evidence suggests a certain degree of introgression between the cactophilic siblings Drosophila buzzatii Patterson & Wheeler and Drosophila koepferae Fontdevila & Wasserman.

In all cases, developmental time and larval viability in hybrids was not significantly different from parental lines and, depending on the cross, hybrids developed faster than both parental species or than the slowest species. When data of wing length were included in a discriminant function analysis, we observed that both species can be clearly differentiated, while hybrids fell in two categories, one intermediate between parental species and the other consisting of extreme phenotypes.
