title: Long-term monitoring of the European roller (Coracias garrulus) in Ukraine: is climate behind the changes?
abstract: The European range of the roller was formerly more extensive, but since the 1980s there has been a long-term decline in numbers and in range, particularly towards the north, including much of north-western Ukraine. Our specific goals were to reconstruct the environmentally suitable range of the species in Ukraine before the 1980s, gain better knowledge on its requirements, compare the past and current suitable areas, infer the regional and environmental variables that best explain its occurrence
