Species composition and population fluctuations of alpine bird communities during 38 years in the Scandinavian mountain range
The breeding birds of four low alpine plots in Sweden were surveyed at Ammarnäs (65°50'N; two plots, each 100 ha, for 38 and 36 years), Abisko (68°18'; 130 ha, 12 years), and Anjan (63°45'; 150 ha, 11 years). Mean number of species of each plot was between 8 and 12 per year. Mean dens...
