Ekologiya Zhuravley Tundrovoy Zony Sibiri: Osobennosti Ispol'zovaniya Ekologicheskikh Nish Zhuravlyami Tundrovoy Zony Severo-vostoka Sibiri Sergey Sleptsov Russian edition

Gnezdovye arealy sterkha Grus leucogeranus Pall. i kanadskogo zhuravlya Grus Canadensis canadensis L. perekryvayutsya v severo-vostochnykh subarkticheskikh tundrakh Yakutii. Ispol'zuya razlichnye ekologicheskie nishi v zone sovmestnogo gnezdovaniya, vidy realizuyut potentsial k rostu chislennosti populyatsiy, chto pokazyvayut issledovaniya v basseyne r. Indigirka. Sterkh zdes' obitaet na nizkikh, obvodnennykh uchastkakh tundry vblizi krupnykh ozer, kanadskiy zhuravl' chashche vstrechaetsya na bolee vysokikh i sukhikh uchastkakh. No issledovaniya v basseyne r. Kolyma, gde sterkh preimushchestvenno otsutstvuet na gnezdov'e, kanadskiy zhuravl' bol'shuyu chast' vremeni kormitsya v naibolee nizkikh i obvodnennykh mestoobitaniyakh. Dannyy fakt pokazyvaet, chto obvodnennye zony ne isklyuchayutsya kanadskim zhuravlem dlya kormleniya. V basseyne r. Indigirka, veroyatno, on vytesnyaetsya sterkhom v druguyu ekologicheskuyu nishu na bolee vysokie yarusy tundry, chto ne okazyvaet znachitel'nogo vozdeystviya blagodarya plastichnosti i tolerantnosti vida. V rabote predstavleny novye fakty po gnezdovomu, vyvodkovomu i kormovomu povedeniyu vidov, podcherkivayushchie tesnye vzaimosvyazi organizmov v severnykh ekosistemakh i raskryvayushchie adaptivnye mekhanizmy tundrovykh zhuravley.
