Abstract

According to the data of 1995–2020 surveys conducted in the Sulakskaya and Turalinskaya lagoons on the western coast of the Caspian Sea in Dagestan, as well as according to information about the returns of bands obtained from the banding center of the Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, the geographic dispersion of migrating wader populations was determined, for ten species of which population trends were established. Of the ten model taxa, the abundance decreased in four, increased in two, and remained at the same level in four. There is a correlation between changes in air temperature in the Primorskaya lowland of Dagestan with average annual fluctuations in the abundance of the model group of birds. The dynamics of the number of migrating shorebird populations is determined by hydroclimate cycles, anthropogenic factors, and foraging. It is recommended to introduce a temporary ban on the hunting withdrawal of lapwing, herbalist, snipe and black-tailed godwit until their populations recover steadily.

气候变暖时期西里海干旱海岸水禽的种群动态

摘要

根据1995年至2020年在达吉斯坦里海西岸苏拉克斯卡亚和图拉林斯卡亚泻湖进行的调查数据，以及根据谢维佐夫生态研究所环志中心获得的环带返回信息，俄罗斯科学院的《进化论》确定了迁徙涉禽种群的地理分布，并确定了其中十个物种的种群趋势。在十个模型类群中，有四个丰度下降，两个增加，四个保持不变。达吉斯坦滨海低地的气温变化与模型鸟类丰度的年平均波动之间存在相关性。迁徙鸻鹬鸟类数量的动态由水文气候循环、人为因素和觅食决定。建议暂时禁止田凫、草药师、鹬和黑尾塍鹬的狩猎退出，直至其数量稳定恢复。
