Unlabelled: The consequences of acute disorders of cerebral circulation significantly reduce the patient's life quality. According to official data, movement disorders are observed in 81.2% of surviving patients.

Climate Warming as a Possible Trigger of Keystone Mussel Population Decline in Oligotrophic Rivers at the Continental Scale.

The effects of climate change on oligotrophic rivers and their communities are almost unknown, albeit these ecosystems are the primary habitat of the critically endangered freshwater pearl mussel and its host fishes, salmonids. The distribution and abundance of pearl mussels have drastically decreased throughout Europe over the last century, particularly within the southern part of the range, but causes of this wide-scale extinction process are unclear. Here we estimate the effects of climate change on pearl mussels based on historical and recent samples from 50 rivers and 6 countries across Europe.

[Individual Growth of the Great Ramshorn Snail Planorbarius corneus (Gastropoda, Planorbidae) Embryos].

Individual growth of the great ramshorn snail Planorbarius corneus has been studied by intravital video imaging. As has been observed, the types of growth change over the embryogenesis. The linear dimensions slightly but in a statistically significant manner decrease during the stages of cleavage to blastula.

Irregularity of the Linear Growth of the Margaritifera margaritifera (Bivalvia: Margaritiferidae) Population of the Nemina River, Karelia.

The dependence of shell growth in length and height during ontogeny has been studied in the pearl mussel Margaritifera margaritifera inhabiting the Nemina River (basin of Lake Onega, Karelia). It has been shown that the population is heterogenous based on the height-to-length ratio. It has been found that during ontogeny M.

[Specific Features of Linear Growth Influencing Morphometric Parameters of the Shell in Margaritifera margaritifera (Bivalvia: Margaritiferidae)].

Interdependence of parameters of shell growth in length and height during ontogeny has been studied in the freshwater pearl mussel M. margaritifera. It has been shown that the results of determining the height-to-length ratio depend on at least two factors: shell corrosion in the apical (umbo) zone and regular, rhythmic deviation of this ratio from values expected from linear regression equation.
