[Population structure of beaked redfish (Sebastes mentella Travin, 1951) in the Irminger Sea and adjacent waters inferred from microsatellite data].

Samples of beaked redfish from the Irminger Sea and adjacent waters were examined for polymorphism at ten microsatellite loci. The strategy of the material collection enabled investigation of geographic, bathymetric, and temporal variation of this species. The results did not support the evidence on spatial differentiation and temporal stability of the species distribution, favoring the idea that the water area examined was inhabited by a single pelagic population of beaked redfish.

[Use of the standard theory of electronic transitions in the description of oscillations in the kinetics of electron transfer in reaction centers of purple bacteria].

The standard theory of the electron transfer between donor and acceptor molecules was used to describe oscillations in the reduction kinetics of the intermediate electron acceptor BA and the primary electron acceptor HA. The kinetics of the reduction of BA and HA were simulated on the basis of the model in which one and two accepting modes were used. A principal experiment is offered for the selection of the suitable theory for adequate description of oscillations in the kinetics of electron transfer in the reaction centers of purple bacteria.
