A new method of studying the activity of European mole Talpa europaea (Linnaeus, 1758) with use of digital portable voice recorders is developed. European mole demonstrates polyphasic activity pattern – three peaks of activity alternate three peaks of relative rest. Moles are found to have activity peaks from 23:00 to 3:00 h, from 6:00 to 9:00 h and from 15:00 to 18:00 h, and three periods of rest: from 3:00 to 6:00 h, from 9:00 to 15:00 h and from 18:00 to 23:00 h. Mole’s rest is relative since animals show low activity during periods of rest. Average daily interval between mole passes is 2.5 h. Duration of audibility of continuous single European mole pass by the microphone varies from 11 to 120 seconds. On average, it is 37.5 seconds.

A new method of studying for activity of a semi-aquatic mammal Russian desman Desmana moschata (Linnaeus, 1758) with use of digital portable voice recorders is developed. To identify the burrows in which the recorders were to be installed, the burrows were probed. A probe is a pole pointed at one end with a T-shaped handle at the other end. The researcher's task was to detect the entrance to the burrow, usually under water. The direction of the underground passage is determined by means of the probe. For this purpose, the ground is pierced to detect the hollows in the burrow with the probe starting from the burrow entrance (the probe falls through unevenly). At a distance of 2 to 3 meters from the burrow, in some cases largely depending on the burrow length, the ground is dug up above the burrow in the form of a small well, 10 to 15 cm in diameter. A digital voice recorder was placed vertically in this well, so that the microphone was directed down towards the burrow. Desman noises can be characterized as short series formed as a sequence of contiguous short peaks of 15 to 25 seconds with five second interruptions formed by regular waves of breathing and its movement noises. As a rule, the noise audibility ranges from 1 to 3 minutes.

The activity of the greater mole-rat was studied using a new technique. New data have been obtained on the characteristics of the daily and seasonal underground life of mole-rats in an isolated population in Mordovia. Polyphase daily activity is most pronounced in the spring and early fall periods. In spring, the maximum activity (about 20% of all daily registrations in separate hours) is confined to the periods from 8:00 to 9:00 a.m. and from 3:00 to 4:00 p.m. The peak of activity in the early fall was recorded from 9:00 to 10:00 a.m. At night, the activity of animals in different seasons was stably low. The burrowing activity, as a rule, began after midnight and stopped in the morning before 5:00 a.m. The maximum duration of the dormancy period in the evening in summer months was five hours. Statistically significant differences were obtained for the average number of passages of mole-rats in the burrow per day for different months using the Mann‒Whitney criterion (p < 0.05).

Разработана новая методика изучения активности подземных млекопитающих с использованием цифровых портативных диктофонов. Ранее слепышей регистрировали визуально по выбросам земли над поверхностью почвы. С применением диктофонов стало возможно точно определять, является система нор жилой или нежилой. Кроме того, стало возможным определение времени суток, когда зверьки перемещаются по системе нор. Данная методика для изучения активности млекопитающих, ведущих подземный образ жизни, применена и апробирована впервые.

The article presents the characteristics of the ground daily and seasonal activity of the local steppe marmot populations scattered in the north of the area in central part of European Russia. Revealed the alternation of single-phase and two-phase loops terrestrial activity Marmota bobak during the spring-summer period. For April and June marked single-phase active and revealed a biphasic activity for May, July and August. On average, marmots come out of the holes in the morning 28 minutes after sunrise. They hide in burrows marmots in the evenings, on average 1 hour 16 minutes before sunset.

residing in the Çanakkale Province, Biga County Private Bisev Nursing Home as well as to put instructive suggestions to corporations
in order to develop health care of elder individuals. Questionnaire method was applied through face to face discussions with elder
individuals (n=58 persons). Statistical analysis was conducted on SPSS Clementine 12.0 package program. Descriptive analysis has
been performed for analysis data as well as cross tables have been formed through frequency distribution of participants included in
research, health problems they experience, and variance analysis between disease types and different characteristics. Consequently:
average of elder individuals residing at nursing home is = 78 and they are included in the group of advanced ages. 89,7% of the elder
individuals are covered with social security, 51,7% have income. Activity rate of the elder individuals that they could independently
makes 74%, auxiliary means used mostly by elder individuals are determined as glasses and walking frames or similar. The rate of
individuals not performing any physical activity is high and rate of elder individuals experiencing no health problem makes 81%. The
rate of elder individuals benefiting from care service in the nursing home makes 87,9%. 74,1% of the elder individuals are willing to
live in nursing home. One of the conclusions drawing utmost attention is that even though all of the elder individuals residing at
nursing home have children, they prefer to remain in nursing home.
