    About fifty larvae of Cephenemyia ulrichii Brauer (Diptera: Oestridae), some of them nearly fullgrown third instars, were found in the throat of a roe deer (Capreolus capreolus) in June 2007 near Helsinki in Finland. The parasite is considered to be host specific, occurring only in the moose (Alces alces), and this paper is apparently the first report of a successful infestation in an aberrant host

    Enriching Everyday Experience with a Digital Service: Case Study in Rural Retail Store

    A novel omnichannel service concept was developed and piloted in the context of everyday retail service environment. A starting point for the new service was a need to provide the customers of a small rural retail store with wider selection of goods through integrating web shopping interface to the store’s service processes. One of the driving design principles was to achieve a seamless service experience by a fusion of web and physical retail channels. The findings from the case study were analysed from the viewpoint of store customers and personnel. Over half of the interviewed customers stated they were likely to use the novel retail service in the future. Previous experience with online shopping appeared to have a direct, positive effect on the customers’ willingness to adopt the service into use. The hands-on demonstration was proved to be an advantageous way for introducing the novel service to potential users. Personnel’s attitudes towards the service concept were in general enthusiastic and positive; however the service also invoked some initial concerns mostly related to additional work load. The personnel also clearly appreciated the positive effects of the new service on the store and customers

    Susceptibility to intestinal parasites and juvenile survival are correlated with multilocus microsatellite heterozygosity in the Capercaillie (Tetrao urogallus)

    Inbreeding can have a negative influence on several life-history traits as well as disease resistance in birds and mammals through different geneticmechanisms. Endangered and declining populationsmay be at particular risk for inbreeding. The level of inbreeding can be estimated by assessing individual heterozygosity at neutralmicrosatellitemarkers.We studied the relationships between intestinal helminth infections, age, sex and heterozygosity in Capercaillie (Tetrao urogallus).We assessedmicrosatellite heterozygosity at eight autosomal loci and calculated two different indices (multilocus heterozygosity MLH and mean d 2) to quantify individual heterozygosity. Capercaillie were infected by three species of cestodes (Paroniella urogalli, Skrjabinia cesticillus and Hymenolepis sp.) and one nematode species (Ascaridia compar).We found that the probability of nematode infection decreased as the level of heterozygosity (measured by mean d 2) increased. Also, the intensity of nematode infection decreased as heterozygosity (measured by MLH) increased. However, we did not observe correlation between heterozygosity and the occurrence of cestodes. In addition, heterozygosity (bothMLHandmean d 2)was dependent on age class: adultCapercaillie had higher heterozygosity than juveniles. Results suggest selection for heterozygosity which can be reinforced by differences in genetic parasite resistance

    Description and life-cycle of Taenia lynciscapreoli sp n. (Cestoda, Cyclophyllidea)

    A new species of tapeworm, Taenia lynciscapreoli sp. n. (Cestoda, Cyclophyllidea), is described from the Eurasian lynx (Lynx lynx), the main definitive host, and the roe deer (Capreolus capreolus and C. pygargus), the main intermediate hosts, from Finland and Russia (Siberia and the Russian Far East). The new species was found once also in the wolf (Canis lupus) and the Eurasian elk/moose (Alces alces), representing accidental definitive and intermediate hosts, respectively. The conspecificity of adult specimens and metacestodes of T. lynciscapreoli sp. n. in various host species and regions, and their distinction from related species of Taenia, was confirmed by partial nucleotide sequences of the mitochondrial cytochrome c oxidase subunit 1 gene. Morphologically, T. lynciscapreoli sp. n. can be separated unambiguously from all other species of Taenia by the shape of its large rostellar hooks, particularly the characteristically short, wide and strongly curved blade. If the large rostellar hooks are missing, T. lynciscapreoli may be separated from related species by a combination of morphological features of mature proglottids. It is suggested that T. lynciscapreoli has been present in published materials concerning the tapeworms of L. lynx and L. pardinus in Europe, but has been misidentified as Taenia pisiformis (Bloch, 1780). Taenia lynciscapreoli sp. n. has not been found in lynx outside the range of roe deer, suggesting a transmission pathway based on a specific predator-prey relationship. The present study applies a novel, simple approach to compare qualitative interspecific differences in the shape of rostellar hooks.Peer reviewe
