It\u00e4meress\u00e4 on havaittu uusi endeeminen kampelalaji, It\u00e4meren kampela, jota ei voida erottaa kampelasta ulkoisten ominaisuuksien perusteella.

Its formation history and current state cause adaptations and even drive speciation. A new endemic flounder species, the Baltic flounder, has been found in the Baltic Sea and new information about its ecology is needed for species conservation and fisheries management purposes. The aim of this study was to examine whether there are differences in otolith shape between European flounder and Baltic flounder and evaluate whether otolith shape analysis can be used to identify these two flounder species. Additionally, it was studied whether shape analysis can recognize a separate population of European flounder from Lake Pulmankij\u00e4rvi, Northern Lapland. Formerly collected, already identified, otolith samples were used in this study. Otoliths were photographed, and images were analyzed with statistical software R\u2019 shapeR package. Analyses included Wavelet and Fourier reconstructions of otolith outlines, ANOVA like permutation test for correspondence analysis, cluster analysis and linear discriminant analysis. Additionally, ANOVA was used to study collected otolith size variables. Otolith size variables did not differ statistically significantly between species, between left and right otolith or between different sides of an otolith. There were statistically significant differences in otolith outline shape when all groups were studied together. The highest total classification rate between all groups was 74%. The total classification rate between European flounder from Baltic Sea and Baltic flounder was 77%, but there were no statistically significant differences in otolith outline shape either with standard Wavelet or Fourier coefficients. The total classification rate between European flounder samples from the Baltic Sea and Lake Pulmankij\u00e4rvi was 65%, and between European flounder from the Lake Pulmankij\u00e4rvi and the Baltic flounder 90%. However, when classification success was studied for each group, the method could classify most of the Baltic flounder samples correctly, while other groups it classified poorly. Outline shape analysis of otoliths is therefore not a reliable identification method for the studied species. Future studies should examine if the classification rate of shape analysis could be improved.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2023-06-30T06:32:52Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-06-30T06:32:52Z (GMT).
