The terrestrial and freshwater invertebrate biodiversity of the archipelagoes of the Barents Sea; Svalbard, Franz Josef Land and Novaya Zemlya
Arctic terrestrial ecosystems are generally considered to be species poor, fragile and often isolated. Nonetheless, their intricate complexity, especially that of the invertebrate component, isExpand
Persistent organic pollutants, heavy metals and parasites in the glaucous gull (Larus hyperboreus) on Spitsbergen.
It is concluded that the contaminant levels found in glaucous gulls do not cause immune suppression severe enough to affect parasite intensity, and a positive correlation was found between cestode intensities and selenium levels and between acanthocephalan intensified levels. Expand
[On a helminthofauna of seabirds of the Archangelskaya Bay ( Northern island of Novaya Zemlya)].
In the Archangelskaya Bay (North Island of Novaya Zemlya), 25 specimens of sea birds have been collected: 5 kittiwakes, 5 murres, 5 little auks, 4 common eiders, 4 purple sandpipers, and 2 glaucousExpand
Relationships between uterus and eggs in cestodes from different taxa, as revealed by scanning electron microscopy
The association between uterus and eggs appears as strong evidence of active trophic interaction (or matrotrophy) between the parent organism and developing eggs. Expand
[A comparative analysis of the helminth fauna of kittiwake Rissa tridactyla (Linnaeus, 1758) and glaucous gull Larus hyperboreus Gunnerus, 1767 from different parts of the Barents Sea].
Cestodes are the base of the helminth fauna of kittiwakes and glaucous gulls of the Barents Sea, by their species richness, prevalence and abundance, and Nematodes and acanthocephalans were represented by a few species with low infection intensity. Expand
Diphyllobothrium dendriticum (Cestoda: Diphyllobothriidae) in the intestinal tract of the herring gull Larus argentatus: Localization and trophic parameters
It was found that D. dendriticum infects the medial section of the small intestine of the herring gull and is caused by the maximal activity of proteases and glycosidases and by the high rate of membrane and cavitary digestion in this section. Expand
The Characteristics of the Helminthofauna of Sea Birds of the Svalbard Archipelago
The parasitologists of Murmansk Marine Biological Institute for the first time performed a complex study of the helminthofauna of sea birds occurring in the Ice Fiord Bay (Western Svalbard) and performed a comparative analysis of the distribution of helminths that complete their development in Birds occurring in different parts of the Barents Sea.

Fine structure of the copulatory apparatus of the tapeworm Tetrabothrius erostris (Cestoda: Tetrabothriidea)
The organization and fine structure of the complex copulatory apparatus of T. erostris (Tetrabothriidea) is investigated by light and transmission electron microscopy and hypotheses on the possible ways of copulation in T. Erostris based on the observed ultrastructure are discussed. Expand
Study of protein metabolism of herring gulls (Larus argentatus Pontop.) infected by trematode Himasthla larina (Trematoda: Echinostomatidae)
The experiments demonstrated the most significant changes in protein metabolism of herring gulls 8–11 days after infection with trematode H. larina. Expand
