Connecting seas: western Palaearctic continental flyway for water birds in the perspective of changing land use and climate
Abstract The western Palaearctic continental flyway that connects the tundra and taiga belts of Russia with north‐west Europe is the major migratory avenue for an estimated 9.3 million herbivorous water birds (swans, geese and ducks). Agricultural practices together with protection measures subsidiz...
