Spatial distribution patterns of larval cytotypes of the Simulium venustum / verecundum complex (Diptera: Simuliidae) on the Avalon Peninsula, Newfoundland: factors associated with cytotype abundance and composition
Using principal component analysis and cluster and regression analyses, larval macrodistribution of Simulium venustum/verecundum complex cytotypes within a drainage basin and along a stream continuum was investigated. Cytotypes included ACD (= Simulium rostratum Lundström) and AA from the verecundum...
