Assessment of the impacts of an oil spill on the populations of common guillemot (Uria aalge) and long-tailed duck (Clangula hyemalis) - an expert kn…

2012

The amount of operated oil transports continues to increase in the Gulf of Finland and in the case of an accident hazardous amounts of oil may be spilled into the sea. The oil accident may be harmful for the common guillemot and long-tailed duck populations. In this study expert knowledge regarding the behaviour and population dynamics of common guillemot and long-tailed duck in the Gulf of Finland was used to build a model to assess the impacts of an oil spill on the mortality and population size of these species. The Bayesian networks were used in the modelling. Based on the results the breeding colony of guillemots in Aspskär may survive in the consequence of recolonization. In conclusio…

Teacher-Student Relations in Two Tibetan Buddhist Groups in Helsinki

2017

AbstractBased on sixteen interviews with members of two Tibetan Buddhist groups in Helsinki, Finland, this article investigates how the role of the guru, power imbalance and power abuse are perceived by the students. This qualitative study aims at understanding what shape the reverence to the Vajrayana teacher takes in the egalitarian environment of a European country, where Buddhism is a relatively new phenomenon. The interviews show that while teachers are not losing importance, ways of choosing and paying respect to them changes. They also reveal confusion in defining abuse, and emphasis on personal agency and teachers’ accountability for avoiding it.

Host specificity of Argulus coregoni (Crustacea: Branchiura) increases at maturation.

2007

SUMMARYWe tested the hypothesis that host specificity in ectoparasites does not depend exclusively on the features of the host but also on surrounding habitats, using 2 fish ectoparasites, Argulus coregoni and A. foliaceus (Crustacea: Branchiura), occurring sympatrically in Finnish lakes. Although these parasites are considered to be of low specificity, we found that the larger of the 2 species, A. coregoni developed a pronounced preference for salmonid hosts at the beginning of maturation (defined by the presence of copulating specimens). Argulus foliaceus infects a much wider range of fish hosts. We showed that specialization of A. coregoni on salmonids does not necessarily result from in…

Efficacy of emamectin benzoate in the control of Argulus coregoni (Crustacea: Branchiura) on rainbow trout Oncorhynchus mykiss.

2004

Efficacy of in-feed treatment with emamectin benzoate (Slice) for the control of ectoparasitic Argulus coregoni on rainbow trout Oncorhynchus mykiss was tested under laboratory and field conditions. In both experiments fish were fed with fish feed to deliver a therapeutic dose of 0 (control) or 50 microg emamectin benzoate kg(-1) d(-1) (treatment) for a period of 7 d. After 3 d of challenge with A. coregoni in the laboratory, the infestation level in treated fish was lower than that observed in the controls (p0.001). Efficacy of 100% against newly hatched A. coregoni metanauplii and adults and 80% against juveniles was observed. In the field, trial medication was undertaken at 2 sections on…

Spatial and temporal structure of the trematode component community inValvata macrostoma(Gastropoda, Prosobranchia)

2008

SUMMARYWe conducted the first comprehensive study on the spatiotemporal structure of trematode communities in the large-mouthed valve snail,Valvata macrostoma. A total of 1103 snails were examined monthly between May and October 2007 from Lake Konnevesi, Central Finland, from a shallow (1–2 m deep) and an offshore site (5–6 m deep), located ca. 50–70 m apart. Snails were infected by 10 trematode species. The species composition and prevalence were strikingly different between the sites with high species diversity in the shallow site (all 10 species; total prevalence of sporocysts/rediae 12·1%, metacercariae 55·4%) compared to the deeper site (3 species; prevalence 15·0% and 1·9%, respective…

Maskuliinisuus Tom of Finlandin teoksissa

2011

Tom of Finland eli Touko Laaksonen (1920-1991) oli suomalainen taiteilija, joka tuli tunnetuksi homoeroottisena kuvataiteilijana ja joka sai elinaikanaan Suomen ulkopuolella enemmän julkisuutta kuin Suomessa. Laaksosen teokset representoivat korostetun maskuliinista miestä, jonka positiivisuus ja hyväntuulisuus olivat homoseksuaaliselle esitystavalle ajallisessa kontekstissa uutta ja maskuliinisuus hämmentävän heteroseksuaalista. Tutkimuksessa keskityn tarkastelemaan, millainen maskuliinisuuden esittämistapa teoksissa on. Päätarkoituksena on tutkia, millaista maskuliinisuutta Tom of Finlandin kuvat representoivat, kuinka kuvissa esitetty mies kehittyy ja muuttuu ajan ja yhteiskunnallisen ko…

Bone mineral density and physical activity in 50–60-year-old women

1991

Abstract The bone mineral density (BMD) of the calcaneus was measured utilizing a single energy photon absorption method in 108 women, aged 50–60 years. The women who participated in vigorous exercise two or more times a week or whose total physical activity amounted to 4 h a week had significantly higher BMD values than those who exercised less than two times a week or did less than 4 h physical activity a week. The physically active women also showed higher values for leg extension force and maximal oxygen uptake. BMD and leg extension force were positively correlated, whereas correlations between BMD and body mass, and the width of the calcaneus were negative. When other life-style varia…

Epizootiology of protozoans in farmed salmonids at northern latitudes

1997

Abstract Protozoan ectoparasites were examined in a northern salmonid fish farm over a 10-year period, June 1984–May 1994, by the same researcher, with similar catching and sampling procedures throughout. Husbandry procedures remained constant during the study, e.g., fingerlings were kept in steel tanks and yearlings in both steel tanks and earth ponds. Ichthyobodo necator, Chilodonella hexasticha and Ichthyophthirius multifilurs infections were treated with formalin, salt and malachite green-formalin baths, respectively, whenever any parasites were found. Altogether 10 790 randomly sampled salmon (Salmo solar), sea trout (S. trutta m. trutta) and brown trout (S. trutta m. lacustris) were s…

Finnish salmon resistant to Gyrodactylus salaris: a long-term study at fish farms.

1996

Abstract The occurrence of Gyrodactylus salaris on Baltic salmon ( Salmo salar ), sea trout ( S. trutta m. trutta ) and brown trout ( S. trutta m. lacustris ) was examined from 1984 to 1993 at 4 fish farms (A, B, C and D) that produce smolts for stocking in northern Finland. No G. salaris was found on the sea or brown trout, but it did occur on salmon for 6–7 years at farms B, C and D, the prevalences of infection being 9.5%, 17.7% and 8.8% for salmon yearlings and smolts during that time, respectively, but less than 1.2% for fingerlings at farms B and C. Only brood stock salmon were infected at farm A in 4 years. The abundances of G. salaris increased during the second winter of each year …
