Interaction between moose (Alces alces) and the willow Salix phylicifolia (Salicaceae)

Updated 2003-04-24

The project deals with the interaction between moose (Alces alces) and one of its major food plants (Salix phylicifolia, - Salicaceae). This plant was chosen after previous investigations in this area. On one hand the food selection of moose will be investigated. On the other hand the influence of browsing on the changes of chemical compounds and morphological structures of the food plant will be studied. While the quality and the browsing degree on Salix phylicifolia will be recorded in natural habitat, the induction of changes in the plant metabolism caused by moose and its subsequent consequences for the food selection will be studied experimentally. The primary plant compounds will be analysed by standard methods. Specific secondary plant compounds will be analysed by HPLC (High Performance Liquid Chromatography). The results of the chemical analyses should be used to calibrate near infrared reflectance spectra (NIRS) to determine the quality of the food. Then the spectra should be used to predict the probable use of S. phylicifolia by moose in this area.
