  1. 1. Ultrastructural and systematic studies of cecidomyiidae (Diptera)

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gallmyggor; tvåvingar; cecidomyiidae; diptera;

    Abstract : Examination of the abdomen of the adult female and the head capsule of the mature larva indicates the grat utility of the Scanning Electron Microscope (SEM) in examining structures when searching for useful characters to deal with the taxonomy and phylogeny of gall midges (Diptera: Cecidomyiidae). Some of the structures found represent adaptations of limited value for phylogenetic considerations at higher levels. READ MORE

    Abstract : The evolution of elaborate male ornaments via sexual selection is well-understood while the selective pressures acting on female ornaments remains unresolved. Female ornaments in species with strong sexual selection on the male homologue of the ornament were originally thought to result from an intersexual genetic correlation. READ MORE
