Winged morph of the high arctic aphid Acyrthosiphon svalbardicum (Hemiptera: Aphididae): abundance, reproductive status, and ecological significance
Abstract The aphid Acyrthosiphon svalbardicum Heikinheimo, which is endemic to Svalbard and feeds exclusively on eightpetal mountain-avens, Dryas octopetala L. (Rosaceae), has developed a series of adaptive traits to cope with the harsh conditions of the High Arctic. Prior to this study, only a sing...
