Spatial and temporal dynamics of abundance of nesting waders on the taimyr peninsula // International Wader Study Group Conference, 15-18 September 2017, Prague, Czech Republic. Abstracts. — Czech University of Life Sciences Prague, 2017. — P. 98–98. Abundance of nesting waders was studied in 1994-2016 in three different regions on southeastern (72o51' N, 106o04' E), central (74o09'N, 99o34'E), and northwestern (73o21' N, 80o32' E) Taimyr Peninsula. We used nest searches on sample plots for assessment of wader nesting densities. This parameter varied greatly between years. The structures of wader communities were more similar in similar habitats of different regions than in different habitats of the same region. The abundance of nesting waders and variation of this parameter were the highest in floodplain habitats, and the lowest on watersheds. Over the study period on southeastern Taimyr (1994–2014), we revealed a long-term tendency of decrease in abundance of nesting waders on watersheds and its increase on floodplains. This tendency was related to the climate warming, which took effect in the growth of spring temperatures, earlier snowmelt and flooding, and earlier availability of the nest sites suitable for waders in floodplain habitats.
