The impact of weather and the phase of the rodent cycle on breeding populations of waterbirds in Finnish Lapland
Climate change may affect bird populations both directly by changing theweather conditions, and indirectly through changes in the food chain.While both theoretical and empirical studies have shown climate change having drastic impacts on polar areas, its consequences on Arctic bird species are still...
