The characteristics of the biogenic element of the runoff fr om the drainage areas of the Gulf of Finland basin experiencing a lim ited anthropogenic impact
This article analyses characteristics of 25 rivers of the Gulf of Finland basin where the monitoring of the streamflow chemical composition was performed. The authors consider the dynamics of biogenic element content in the streamflow, the relation of the drainage areas to certain landscapes, the share of agricultural lands and tillage in the drainage areas, the forest-land percentage, a rural population density, and the forest age and type.

Initiative as a type of document
... "receiver"), "function," "information," "modality," "structure," "space," and "time."
Three levels of hierarchy of parameters are distinguished, determining their significance as genre-forming elements. It is established that the features of first-level parameters, such as the collectivity of the sender and the dual nature of the receiver, the unity of initiative functions in informing and influencing, determine the specificity of second-level ...
Element accumulation in bryophytes in peatland ecosystems of the Kaliningrad region, Russia
... Br, Rb, Sr, and Ca) was determined. Statistically significant differences were found in the concentrations of Mn, Zn, Ni, Br, and Rb in the mosses. A high correlation was observed between iron and calcium, which may indicate a common source of these elements entering the plants. The moss species Aulacomnium palustre and Sphagnum centrale were identified as having accumulation capabilities similar to the reference species Pleurozium schreberi.
