| description | Chemical -- plant defences as mechanisms affecting herbivore populations have been debated during the past decade. Several authors have questioned the hypothesis, but the present study shows that collared lemmings (Dicrostonyx groenlandicus) in northeast Greenland prefer food plants with a lower catechin content. Dicrostonyx species are known to have specialised on shrubs, especially Dryas spp. and Salix spp., rather than graminoids like other related microtines. Bioassays were conducted using food material from Dryas spp., Salix arctica, Vaccinium uliginosum, Kobresia myosuroides and Poa glauca. Enclosures with the first three species mentioned were further treated by clipping to simulate herbivory in order to induce the production of the plant defence compound catechin. Treatment increased the catechin content in Dryas spp., S. arctica (females only) and V. uliginosum significantly compared with the catechin concentration in untreated plants. These elevated catechin concentrations had a significantly negative effect on the consumption rate of Dryas spp. and female S. arctica by collared lemmings. |
