Abstract

This article provides results of a helminthological study of two seabird species, the Black-Legged Kittiwake (Rissa tridactyla Linnaeus, 1758) and the Brünnich’s Guillemot (Uria lomvia Linnaeus, 1758), from Russkaya Gavan Bay, Severny Island, Novaya Zemlya Archipelago. A total of five species of helminth parasites were identified in kittiwakes and six species in guillemots. The cestode Tetrabothrius erostris and the nematode Stegophorus stellaepolaris proved to be common helminth parasites for both seabird species. Two species, T. erostris and the acanthocephalan Corynosoma strumosum, were found for the first time in seabirds from Novaya Zemlya. Brünnich’s guillemot was recorded as a new definitive host for C. strumosum in the Barents Sea region. The main characteristic feature of the helminth infestation in birds from northern Novaya Zemlya is the absence of trematodes, endemic and highly specific parasite species, as well as helminths with freshwater life cycles. The prevalence of helminth parasites in kittiwakes and guillemots from different parts of the Barents Sea is analyzed. It has been established that the nematode S. stellaepolaris exerts the most pronounced negative impact on the physiological condition of Brünnich’s guillemots.

黑腿Kittiwake（Rissa tridactyla Linnaeus，1758年）和Brünnich的Guillemot（Uria lomvia Linnaeus，1758年）在新斯科舍群岛塞弗尼岛Russkaya Gavan湾的蠕虫

摘要

本文提供了对两种海鸟进行蠕虫学研究的结果，这两种海鸟分别来自Novaya Zemlya群岛的Russkaya Gavan Bay，Russkaya Gavan Bay （Rissa tridactyla Linnaeus，1758）和Brünnich的Guillemot（Uria lomvia Linnaeus，1758）。在基蒂沃克人身上总共发现了五种蠕虫寄生虫，在海雀科动物中发现了六种。该绦虫Tetrabothrius erostris和线虫Stegophorus stellaepolaris被证明是两个海鸟常见的肠虫寄生。两种种，T。erostris和棘头棘皮疣首次在Novaya Zemlya的海鸟中发现。勃朗尼希的海雀科的母鸟被记录为巴伦支海地区弹状梭菌的新定型寄主。在Novanova Zemlya北部的鸟类中，蠕虫感染的主要特征是没有吸虫，地方性和高度特异的寄生虫物种，以及具有淡水生命周期的蠕虫。分析了来自巴伦支海不同地区的基蒂沃克人和海雀科的蠕虫寄生虫的患病率。已经确定，线虫S. stellaepolaris对Brünnich海雀科的海象的生理状况产生最明显的负面影响。
