Seasonal trends in chemical composition of reindeer forage plants on South Georgia
Read more of: Seasonal trends in chemical composition of reindeer forage plants on South GeorgiaSystematic observations were made on reindeer feeding behaviour during 1973–74, and seven phanerogams and three bryophytes were selected for sampling during the following year. Material of the principal plant species […]
