This scanning electron microscopy study of the morphology of pennate diatoms (Achnanthidium eutrophilum (Lange-Bertalot) Lange-Bertalot, Aneumastis stroesei Mann et Stickle, Gomphonema italicum Kützing, G. pala Reichardt, G. vibrio Ehrenberg, Punctastriata ovalis Williams et Round) from phytoperiphytic communities in the cooling pond of the Chernobyl nuclear power plant and natural lakes of the Exclusion Zone (Glyboke and Daleke lakes) has revealed a higher variability in quantitative characteristics (valve length and width, number of striae in 10 µm). At the same time, no variability of qualitative features (shape of valve, axial and central area, raphe and striae arrangement) has been observed in these species. In A. eutrophilum, the number of striae in 10 µm differ from the published data, in A. stroesei – the valve length, in G. pala, G. vibrio and P. ovalis – the valve length and width. The range of variation in the number of striae in 10 µm in G. pala and the valve length and the number of striae in 10 µm in A. stroesei and G. italicum disagree with the literature data. The first electron micrographs of the inner surface of the valve and the corresponding data on its morphology are obtained for A. eutrophilum, A. stroesei, G. italicum, G. pala and G. vibrio.

First Time

The aim of the publication is to determine the prerequisites of and to elaborate on the foundations of the Exclusion Zone reintegration in order to address the issue of rational development of urban-planning documentation complex regarding the legitimacy of said territory exploitation. It is established that for the implementation of the «Radioactive waste management strategy» the production complex «Vector» is being constructed on the Exclusion Zone territory; a powerful park of renewable energy generation is being created to implement the «Chornobyl - a Territory of Change» strategy; a Chornobyl Radiation-Ecological Biosphere Reserve was established to support and increase the barrier function of the zone; in order to promote the Safe Chornobyl brand-name, the tourist traffic is being increased and the conditions for the visitors are improving. In the absence of developed and approved city planning documentation, the listed above causes the problem of legitimacy and rationality of the exclusion zone territory use. The paper for the first time raises the question of the need to elaborate the concept of functional planning of the Chornobyl NPP exclusion zone territory and the development of the design-planning complex (urban planning documentation): from the territory.

Ultraoligotrophic Lake

On the basis of the studied materials from the ultraoligotrophic lake Elgygytgyn (Chukotka), a rare for the flora of Russia diatom species Navicula schmassmannii was recorded. In the studied populations of the species a wide variability of morphological quantitative (valve length and width, the number of stria in 10 μm) and qualitative (the shape of the valve and the central area) features was marked. It made the basis for emending of the species diagnosis.
