Bird populations in the Kluane Mountains, southwest Yukon, with special reference to vegetation and fire
Bird populations were studied in relation to vegetation communities in the Kluane Ranges, Yukon. Information on species diversity and abundance was collected on 39 linear 4-ha plots in eight communities by noting birds heard and seen on repeated walks over each plot. Bird populations in tundra and s...
