Hermania indistincta (Ohnheiser et Malaquias, 2013) comb. nov. is recorded for the first time for the Barents Sea and the Russian marine fauna. Based on the morphology of the studied specimens the diagnosis of the genus Hermania Monterosato, 1884 is emended. The taxonomic significance of the spiral shell sculpture in the genus Hermania is discussed. © 2015 Zoological Institute, Russian Academy of Science.

Macrophytes play a significant role in the functioning of hydroecosystems. Their activities include changes at the physiological and anatomical levels toward the action of various pollutants. This study was intended to reveal some features in aerenchyma formation in roots of Typha angustifolia exposed to various concentrations of nitrate nitrogen and salicylic acid. It was found that the resistance of T. angustifolia to nitrate nitrogen is mediated by redistribution of aerenchyma formation in the root system. The action of salicylic acids results in decreasing influence of nitrate nitrogen in two types of adventitious roots. Features of aeren-chyma formation in the soilborne roots and aquatic ones were different. © 2011.

Typha angustifolia L. is one of the most important helophyte. The aim of this study was to identify morphological and production reactions Typha angustifolia under the action of different concentrations of lead. It was found that lead concentrations of 0.25; 2.5 and 10 mg / l stimulated the growth and production processes in the cattail, but at higher concentrations effect of stimulation was decreased. The highest lead concentration (10.0 mg / l) caused a decrease in the average leaf area. Stimulation of growth and production indicators of cattail plants can be considered as an adaptive response to pollution.
