This paper presents the acoustic features of speech recorded during interactions with foreigners in Danish and Finnish languages in the light of Speech Accommodation Theory. It presents selective aspects of speech attuning to linguistically less-fluent interlocutors in temporal and spectral perspectives. Foreigner-directed speech and native talk were compared in a spectral (F0, vowel space and intensity) and a temporal domain (phones per second). The results were correlated with the participants’ degree of exposure to foreigners and attitude towards them measured by means of a questionnaire. It was concluded that personal attitude towards interlocutors causes hyperarticulation. It was also shown, however, that the differences between the given instances of conversation are the strongest in the temporal domain, and not in the spectral domain.

The aim of this paper is to discuss the composition of Johanna Sinisalo’s novel The Core of the Sun by demonstrating how the author used excerpts of academic text to create the literary world of the novel. As the theoretical foundation, I will use Lubomír Doležel’s research introducing the theory of possible worlds in literary creation. The realia, possibilia, and the transworld identity of the fictional world of Sinisalo’s novel is analyzed on the basis of excerpts from dictionary entries and scientific articles used as world-building elements.

Subfossil remains of a new species of Cladocera (water fleas) of the family Chydoridae in Finland, Alona werestschagini Sinev, were found in the sediments of four lakes above the treeline in northernmost Finnish Lapland. The remains were found in surface sediments of three lakes and in early Holocene sediments of one lake where the species was a pioneer which soon disappeared. The remains of A. werestschagini, except the male postabdomen, closely resemble Alona guttata. In Eurasia A. werestschagini has a wide but patchy distribution in cold climates, suggesting that it is a postglacial relict adapted to cold climate and oligotrophic lakes. Recently it has been found also in Norway and Kola Peninsula. The early Holocene finds indicate that the species spread to northernmost Finland after the retreat of the Scandinavian Ice Sheet. Since the species has been found in lakes in very severe conditions it may be used as a palaeolimnological indicator in sediment studies.

In this study we compared chydorid cladoceran (Chydoridae) taxa and assemblages from sediments of 6 Polish and 6 Finnish lakes and investigated if the difference in climate of these two countries can be detected in the cladoceran data. The data were analysed in terms of I) average relative proportions of chydorid taxa during the history of each lake and by 2) redundancy analysis (RDA) to explain the present effect of environmental variables (altitude, area, maximum depth, mean annual temperature, mean summer temperature and length of the growing season) on species abundances. The redundancy analysis (RDA) enabled us to distinguish groups of taxa I) with a high thermal preference 2) associated with small, cold-water lakes and 3) associated with shallow lakes. There are clear differences in the dominant chydorid taxa and in the relative proportions of many other chydorid taxa between the two countries since the end of the last glaciation. Although these differences first of all appear to reflect the climatic difference, the influence of many other environmental factors, controlling the living conditions of particular chydorids have been raised and considered. Further studies with larger data are needed before the role of climate can be reliably separated from other elements of environment.

The present work is a part of the development of a method which uses the relative proportions of asexually and sexually reproducing chydorid females to reconstruct the length of the open-water season. Surface sediments (5 cm) of Lake Aitajärvi, northern Finnish Lapland, were examined for modern and recent proportions of chydorid cladoceran ephippia in subarctic climate near the pine limit. The total chydorid ephippium proportions (TCE) were steadily 9.5-9.7 % in the Aitajärvi sediment but declined to 8.4 % in the uppermost sample. The result was compared with the surface sediment TCE from four lakes in southern Finland where it varied between 3-6%. It was also compared with the TCE from two lakes in northernmost Finnish Lapland above the treeline in very severe climate, where it was 26-30 %. These very high values suggest that there might be a threshold in climate conditions between Aitajärvi and the two northernmost lakes that alters the reproduction of chydorids towards an even more important role of sexual reproduction.
