Floral Herbivory of Dryas octopetala by Svalbard Reindeer
In polar semidesert communities of northwest Spitsbergen the reproductive potential of keystone vascular plant species, such as Diyas octopetala, is currently being constrained by low summer temperatures, resulting in the infrequent production of viable seeds. This study tests the hypothesis that su...
