Identification of two cryptic Baltic Sea flounder species using otolith shape analysis by Koivunen, Henna

“…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 Pulmankijärvi, Northern Lapland. …”

Toxicity of uranium to two species of freshwater algae in Finnish natural freshwaters containing dissolved organic carbon by Hellmuth, Jaakko

“…There was a significant, roughly 10-fold, difference in sensitivity towards U toxicity between the two species studied. Toxicity values (IC50) for Desmodesmus subspicatus were between 2.01 and 5.50 mg/l U and for Raphidocelis subcapitata between 0.11 and 0.80 mg/l U. …”

Chronic toxicity of sodium sulphate to two age groups of freshwater pearl mussels Margaritifera margaritifera by Hu, Xiaoxuan

“…Since sulphate toxicity is also context-specific and dependent on water hardness of the region, local data are needed in the effective development of regional environmental quality standards (EQS). As part of a Species Sensitivity Distribution project to derive sulphate EQS in the soft Finnish freshwaters, this study examined the chronic effect of sulphate on endangered keystone species, Margaritifera margaritifera. 7-week-old juveniles and 2-year-old mussels were exposed to different sulphate concentrations in soft water for 28 days. …”
