Bryoflora of state integrated nature reserve "Valamazskyi" (Udmurt Republic)
摘要
The article provides the results of bryoflora study carried out at state integrated nature reserve "Valamazskyi" (the Udmurt Republic). Bryoflora of the nature reserve is characterized by a predominance of mesophytic ground-layer bryophytes, most of which are concentrated in forest and coastal aquatic phytocenoses. Two species of bryophytes listed in the Red Book of the Udmurt Republic grow in the nature reserve.
Effect of ATP on protein composition of nervous fiber during regeneration
摘要
The effect of ATP on the protein composition of the peripheral nerve myelin and axon fractions in case of damage was investigated. The dependence of the qualitative protein composition affected by the administration of ATP was found out. The presence of the proteins indicates the process of nerve regeneration and an increase in their concentration shows the effect of ATP on the protein synthesis processes.

Brief overview of information system for Sprygin herbarium at Penza State University (PKM)
摘要
The article considers the current state of the Sprygin Herbarium at the Penza State University. The need to develop a custom-made information system for the herbarium, taking into consideration its specificity, is shown. The main functions of such system are described. The current development of the project and the prospects of work are presented.
Protective effects of biologically active substances on viability of onion (Allium Cepa L.) Epidermal cells under short-term metal stress
摘要
We studied the effect of growth regulators (PGRs) on the viability of onion epidermal cells exposed to short-term metal stress (1 and 10 mM of heavy metal ions). After 2 h. the metal exposure has reached sub-lethal (at 1 mM Ni2+ or Cu2+ and 10 mM of Co2+, Zn2+ or Ni2+) and lethal (at 10 mM of Cu 2+) levels. In some cases, the PGR neutralized (partially or completely) the negative HM effects.
On rare fungi of republic of Mordovia
摘要
Data on the rare fungi included in the Red Book of the Republic of Mordovia are provided. In the autumn of 2017 macromycetes were studied in the Atyashevo municipal district and the Oktyabrsky district of the city of Saransk. The composition of mass species and new locations of three rare macromycetes were found out: Lycoperdon mammiforme, Fistulina hepatica and Hericium coralloides. The collected data will be used in the regional version of the Red Book of Endangered Species of Russia.
Chlorophyll fluorescence parameters to assess photosynthetic apparatus of maize hybrids under stress
摘要
The article presents the results of an assessment of the photosynthetic apparatus of maize hybrids under stress of high and low temperatures by using the parameters of chlorophyll fluorescence. The reactions of photosynthetic apparatus of the stressed hybrids differed slightly. The most destructive high and low temperatures were found out.
Bioindication of Insar river using macrozoobenthos and fluctuating asymmetry of fish
摘要
Bioindication of the Insar River shows that the Ruzaevka industrial hub have a slight effect on the saprobity and severity of the goldfish fluctuating asymmetry. Noticeable negative changes were observed in the areas after the inflow of wastewater treatment facilities of the city of Saransk. Benthic complexes are restored at the lower course of the river.
On flora of peat pits near village of Yakshino (Teykovo district, Ivanovo region)
摘要
The preliminary data on the flora of the peat pits located near the village of Yakshino are provided. The study was completed in 2017. As a result, 85 species of vascular plants belonging to 3 divisions, 4 classes, 32 families and 68 genera were observed. Biomorphological, ecological and phytocenotic analysis of the flora was carried out. Rare and alien species were identified.
Solidago Canadensis L. (Asteraceae) in city of Izhevsk
摘要
The article provides the results of the studies on the propagation of one of the invasive species on the territory of the city of Izhevsk – Solidago canadensis L. Data on the centers of its invasions is presented. The main ecotopes of Solidago canadensis L. are road borders, wild lands, forest edges. The largest packings of goldenrod are observed in the Industrial and the Ustinovsky districts. That makes 55.5% of all identified places of growth. Features of biology of the seeds of the species are studied.
