Dependence of floodplain birds’ dynamics on the spring flood height and duration in the middle Ob River
Abstract Inter-annual variations in the total number of birds in floodplains of rivers are mainly associated with their flooding. The minimum population density during the nesting period was in a year with high and prolonged spring floods. The restoration and maximum development of shrubs took place...
