В работе представлены результаты многолетних исследований видового состава растений Мордовии с целью выявления кормовых видов степного сурка. Установлено, что кормовая база представлена 105 видами из различных семейств. Наибольшее значение в рационе питания имеют растения из семейств Сложноцветные (Compositae) (27 видов), Злаки (Gramineae) (23 вида), Бобовые (Leguminosae) (16 видов). Среди кормовых видов растений по экологической градации в отношении воды на всех участках колоний преобладали представители группы мезоксерофитов. Мезофитные формы уступают мезоксерофитам. При распределении поедаемых сурками растений выяснено, что большинство из них (от 91,9 до 94,2%) относятся к светолюбивым. Анализ видов кормовых растений, произрастающих на разных участках колоний, по составу жизненных форм выявил преобладание многолетних трав (от 74,3 до 79,1%).

Chlorophyll and carotenoid content (ChCar), lipid peroxidation (LP) and growth parameters (GP) in plants are often used for environmental pollution estimation. However, the nonmonotonic dose–response dependences (hormesis and paradoxical effects) of these indices are insufficiently explored...

Action potential is considered to be one of primary responses of a plant to action of various environmental factors. Understanding of plant action potential propagation mechanisms requires experimental investigation as well as a simulation; however, a detailed mathematical model of plant electrical signal transmission is absent. Here, the mathematical model of action potential propagation in plants has been worked out. The model is a two-dimensional system of excitable cells; each of them is electrically coupled with four neighboring ones. Ion diffusion between excitable cell apoplast areas is also taken into account. The action potential generation in a single cell has been described on the basis of our previous model. The model simulates active and passive signal transmission well enough. It has been used to analyze theoretically the influence of cell to cell electrical conductivity and H+-ATPase activity on the signal transmission in plants. An increase of cell to cell electrical conductivity has been shown to stimulate an increase of the length constant, the action potential propagation velocity and the temperature threshold, while the membrane potential threshold being weakly changed. The growth of H+-ATPase activity has been found to induce to the increase of temperature and membrane potential thresholds and the reduction of the length constant and the action potential propagation velocity.

Presented by Academician M.A. Fedonkin July 31, 2009. DOI: 10.1134/S0012496610020158. This is the first time it was shown that the nanoparticles of gold (Au) in substantial amount bind to the living biomass of the aquatic macrophyte, Ceratophyllum demersum. The concentrations of Au were measured in the samples of the phytomass of the macrophyte using neutron activation analysis (NAA). As a result of the binding and/or immobilization of the nanoparticles, the amount of Au in the samples of the phytomass increased manifold above the background level of gold in the plant tissues. The increase was by two orders of magnitude. The new data added some new information to the modern vision of the multifunctional role of the biota in the migration of elements in aquatic ecosystems. Also, the result added new information to the studies of interactions of Au with organisms that may contribute to new biotechnologies.

Lomonosov Moscow State University, Moscow, 119991 Russia b Vernadsky Institute of Geochemistry and Analytical Chemistry, Russian Academy of Sciences, ul.Kosygina 19, Moscow, 119991 Russia Study of biogenic migration of elements is an important line of biosphere research [1–8]. Biogenic migration of elements in aquatic ecosystems, both freshwater and saltwater, is important for water self- purification and quality formation [9–11]. Data on element accumulation and binding by aquatic organisms, including macrophytes, are important for analyzing the organisms’ important role in biogenic migration of elements in aquatic ecosystems. The concentrations of some elements were determined earlier in different biogenic samples, including hydrobionts and biogenic detrital substances [9, 10]. However, these data were based on a limited set of organisms and elements. There are no published data on either gold (Au) content in Ceratophyllum demersum L. or interaction between Au nanoparticles and aquatic macrophytes. The goal of this work was to study the immobilization of Au nanoparticles added to the water medium of microcosms in the presence of macrophyte hydrobionts C. demersum L.
