“…Following these expeditions, a schematic map was produced by Weslawski & Malinga (1993) of the wildlife of Franz Josef Land, marking bird colonies observed by recent Russian and Western expeditions. This map also utilised data from previous expeditions noted in Gorbunov (1932), Norderhaug et al (1977) and Uspenskiy & Tomkovich (1987). Bird colonies were distinguished by size (minor colonies <I000 birds, major colonies > 1000 birds) and dominant species.…”

“…A total of 41 bird species has been recorded on the archipelago (Weslawski & Stempniewicz 1995), of which 14 are known to nest (Tomkovich 1984). The majority of species recorded are seabirds nesting in cliff colonies, with over 60 major colonies (each greater than 1000 nesting pairs) identified in the literature (Uspenskiy & Tomkovich 1987), together with many more minor colonies. Estimates by Uspenskiy & Tomkovich (1987) suggest that, during a typical nesting season, the archipelago is home to roughly 200,000 Briinnich' s guillemots (Uria lonzviu), 500,000 little auks (Alle alle), 30,000 black guillemots (Cepphus g y l l e ) , 20,000 fulmars (Fulmarus glacialis) and 20,000 kittiwakes (Rissa rriductylu).…”

Some of the largest nesting colonies of the ivory gull (Pagophila eburnea) in the former USSR are located within the Franz Josef Land archipelago.…”

Supervised classification of digital Landsat satellite images was used to locate seabird nesting habitats in the Russian High Arctic archipelago of Franz Josef Land, a region where the avifauna is poorly known and ecologically vulnerable. Major seabird nesting colonies are readily identifiable in Landsat Thematic Mapper (TM) imagery of the region due primarily to the distinctive spectral signature of vegetation on ornithogenically altered soils below bird cliffs. Supervised image classification was used to pinpoint areas displaying spectral characteristics typical of documented seabird nesting habitats. A total of 101 seabird nesting colony locations identified in Russian and Western literature from 1898 to 1996 was used as training sites to develop spectral signatures from a summer TM image mosaic for use in a supervised maximum likelihood classification. The classified image was thresholded and compared to a map of documented nesting locations. Of the 101 field-documented nesting sites, 96 were clearly identified in the classified image. An inventory was produced of all undocumented seabird habitats suggested by the classification, totalling over 300 sites. The methodology used may be applicable to other arctic regions and is intended as a first step when planning ecological protection zones in remote and inaccessible arctic regions.

Determinants of the little auk (Alle alle) breeding colony location and size in W and NW coast of Spitsbergen

et al. 2019

Many seabirds breed in large aggregations, making it difficult to estimate their population size and habitat preferences. This knowledge is particularly important considering their function in food webs and ecosystem services. In this study, we investigated the factors affecting distribution and abundance of the little auk Alle alle , a seabird considered a keystone species of the Arctic ecosystem. We performed the study on the W and the NW coast of Spitsbergen. Using Generalized Additive Models (GAMs) and Conditional Inference Tree (CIT) we examined factors related to presence/absence and size (estimated number of breeding pairs) of the little auk colonies. We also tested the nesting preferences for geographical features such as aspect, slope angle, altitude, solar radiation, rock type, and distance to foraging grounds. Our findings indicate that the occurrence of little auk breeding colonies is non-random and highly attributed to environmental factors. The probability of colony occurrence was significantly associated with altitude (negative relationship; preference to sites situated lower), solar radiation (positive relationship; the higher radiation, the more likely colony occurrence) and slope (positive relationship; the steeper a slope, the more likely colony occurrence), whilst aspect appeared non-significant (though the probability of colony occurrence peaked at southern slopes). Colony size was significantly associated with rock type (larger colonies in amphibolite and quartzite). The distance to foraging grounds did not appear to affect the probability of colony occurrence and size, implying that birds may choose optimal breeding sites at the cost of longer foraging flights. We estimated the Spitsbergen little auk breeding population at 728 529 (5–95% CI: 479 312–986 352). Spitsbergen comprises ca 1.9% (95% CI: 1.2%–2.7%) of the world breeding population and represents the third most important breeding area for the species, following the W and the E coast of Greenland.

Svalbard rock ptarmigan: a first glimpse into parasite infections

Natural ecosystems are under stress due to climate change and impacts are especially prominent at high latitudes. Manifestations of these changes include northward shifts in the distribution of birds, phenological mismatches, improved survival of parasites in the environment and the arrival of new parasite vectors and intermediate hosts. We collected baseline data on parasite infections in the Svalbard rock ptarmigan (Lagopus muta hyperborea), which is endemic to two High Arctic archipelagos, by sampling 10 birds caught in September–October 2015 in Van Mijenfjorden, Spitsbergen. Five species were found, three endo- and two ectoparasites. The endoparasites included a nematode, Heterakis sp. (prevalence 10%), and two species of Eimeria, all with direct life cycles. The Eimeria species are provisionally called Eimeria sp. A and sp. B (prevalence 50% and 20%; mean intensity 1560 and 1850 oocysts per g faeces, respectively). Both show morphological similarities with known rock ptarmigan eimeriids, but further taxonomic research is needed to describe their phylogenetic relationships. The two ectoparasites, the ischnoceran chewing lice Goniodes lagopi and Lagopoecus affinis, both showed 90% prevalence and a mean intensity of 18.3 and 5.6, respectively. The eimeriids are host specific, and the chewing lice are common parasites of closely related grouse species. On the basis of our knowledge of rock ptarmigan parasites, Heterakis sp. is considered a generalist parasite. The parasite fauna of the Svalbard rock ptarmigan is impoverished compared with conspecific populations in other Arctic locations, such as Iceland and Greenland.
