The study of the prevalence of erythrocyte antigens is important in terms of ensuring immunological safety. The aim of this work is the occurrence establishment of ABO, Rh, Kell and MN groups. In the surveyed population the occurrence percent of Rh-negative people is high that causes a risk of a sensitization on the Rh factor. 11 phenotypes on the Rhesus factor system are revealed. The distribution of phenotypes across the population of Moksha and Erzya is similar. D positive phenotypes containing hetero- and homozygous samples on C antigen are the most widespread. This work continues a series of immunohematologic studies of the population of the Republic of Mordovia, which makes it possible to clarify the genogeographical map of this region and of Russia on the whole.

The article reflects the results of the study of the functional state of the cardiovascular system of 10-11 year old girls going in for acrobatics who live in climatic conditions of the North with the help of the AngioScan-01P diagnostic device. Irregularities of a condition of a cardiovascular system and distress of adaptation are mechanisms established.

The article analyzes the dynamics of the morphofunctional parameters of students for the period of study at the university. The study is based on the results of prospective observations of physical health of 410 students aged 17-22 years during 2010-2016 using the “Student Health Diary”. In the majority of the groups examined, more intensive growth processes and improvements of functional parameters are observed on 2-3 courses, and then on 4-5 courses a decrease in the growth rate of parameters of the physical development occurs.

Modern young adults are actively switching to the individual music listening using a smartphone and headphones. This phenomenon becomes massive, and in the conditions of a university requires, in our opinion, a separate topic and investigation. Specific musical styles that are used to relief psychological and emotional tension may affect not only mental health of students. That’s why we are interested in the issue of the effect of listening to music on vegetative indices of a body and, first of all, the state of the cardiovascular system.

The training system of the sports reserve requires occasional modernization, including the scientific justification of applied training methods, state and recovery, diagnostic monitoring, state marker identifying, modeling and prediction of successful athletic activities. The identified markers of the functional state in conditions of successful sports performance allowed adjusting the state and preparedness, focusing on the leader group.

One of the current problems of the higher education in the Russian Federation is the creation of an environment for the development of physical qualities and the level increase of physical fitness and health of a future specialist in a university. In a university you can manage the students behavior associated with the manifestation of physical activity rather than anywhere else. However the inclusion of students in regular physical exercises causes a self-contradiction between the intention to train - the intention and realization of that intention in practice - the action. The article discusses approaches on overcoming this difficulty on the basis of author’s research results and literature data.

The article discusses the influence of age on the development of disordered motor function at knee joints in elderly women aged 55 to 65 years (n = 46). The intensity of disordered motor function at knee joints was classified with the help of functional index The Western Ontario and McMaster Universities Osteoarthritis Index. The level of functional performance of research subjects was estimated with the help of physical tests. During the correlation analysis it was established that the age of elderly women is the key factor rendering the significant influence not only on the level of functional performance (r = -0,651; p < 0,001) and mobility of tested women (r = 0,736; p < 0,001) but it is also a modifying factor, influencing the progression of functional and degenerative changes in knee joints which appear as a pain (r = 0,618; p < 0,001) and stiffness (r = 0,774; p < 0,001).

The recovery of the beaver's river population occurred due to the invasion of individu-als of the subspecies of Eastern European Castor fiber orientoeuropaeus and the Belarusian C. f. belorussicus with the formation of a habitat in the special climatic and geographic-landscape conditions of the West Siberian Plain in the part of the right tributary of the first order of the Irtysh River - the Tara River and its tributaries. Adaptive behavior of invasive subspecies and their hybrid progeny was realized in three fundamental phases: primary (1957-1966); Transition (1967-2000); Functional (since 2001), and was aimed at overcoming the consequences of high spring floods on the Tara River, frequent summer-autumn floods, and the limited availability of fodder resources.

The work was completed in 2016 (May, June, July, September) in the vicinity of the Nizhnevartovsk city (the floodplain of the Ob River and the mainland). Small mammals were caught in order to determine the state of populations of rodents and insectivores, their role in maintaining tularemia infection; to detect species composition of ixodic ticks, involved in the bearing, circulation and transmission of the causative agent of tularemia Francisella tularensis. Through the study of parasitic arthropods in the vicinity of the Nizhnevartovsk city, 63 individuals of ixodic ticks (at different stages of development - larvae, nymphs) of two species are considered: Ixodes persulcatus and I. apronophorus.

The sanitary-epidemiological and social situations that arise with the increase of stray animal populations have much significance in the life of any major city. The main concern of the work is the determination of sex-age structure of the stray dog population, the regularity of its chronologic distribution in the Surgut area and the Surgut district. The study was conducted from November 2014 till May 2015. The total number of kilometers covered in the city of Surgut is 625, in the settlements of the Surgut district - 210 kilometers. In the Surgut area there were registered 1267 homeless and stray dogs and 419 individuals in settlements of the Surgut district.

6 occurrences of Zygogonium ericetorum Kützing (Zygnemataceae, Zygnematales, Chlorophyta) have been found in the Khanty-Mansi Autonomous Okrug. In this ecotope species the range of рН was between 4.8 to 6.2, the level of bicarbonates was below 2.61 mg/dm3, the color varied between13 to 218 degrees of the chrome-cobalt scale. The total dissolved sollids content in water was within0.01 g/dm3, the total hardness was between 0.04 to 0.17 meq/dm3. The concentration of the dissolved forms of heavy metals was in the following ranges: Fe between 7.9 to 669.5 µg/dm3, Pb between0.03 to 0.61 µg/dm3, Ni between 0.09 to 2.86 µg/dm3, Zn between 10.99 to 42.45 µg/dm3, Cd between0.02 to 0.41 µg/dm3, Cr between 0.00 to 0.35 µg/dm3, Cu between 0.13 to 0.74 µg/dm3, Mn between1.08 to 8.07 µg/dm3.
