BIOTOP PREFERENCES OF MOUSE-LIKE RODENTS ON THE TERRITORY OF THE NATOINAL

PARK SKOLIVSKI BESKYDY

Stetsula N..

Ivan Franko State Pedagogical University of Drogobych 82100, Ukraine Lviv region, Drogobych,Shevchenko str 23 nadya739@ mail.ru Biotope preferences index (Fij) open the interrelation between species and biotopes, the election of species during the using of the territory for their living and allows to value the correlatoin the part of species in a certain biotope to the part of these species among all biotopes to the general amount of animals in this

biotope and among all biotopes. The analysis of the relative biotope attitude allows to confirm the following:

firstly such species (descending index Fij) are characterized by the highest biotope characteristic (Fij0,50) Arvicola scherman is the attitude to meadow (Fij=0,91), Sylvaemus tauricus for beech forest (Fij=0,76), Microtus arvalis for meadow (Fij=0,71), Apodemus agrarius is characteristic for meadow (Fij=0,68), Terricola subterraneus for meadow (Fij=0,67), Sylvaemus sylvaticus is characteristic for mixed forest (Fij=0,62), Sylvaemus tauricus for hornbeam-beech forest (Fij=0,55). Especially bright is a stenotopos Arvicola scherman which avoids more of unmeadow biotopes.

Second, by the biggest amount of species, which gives the priority to a specific biotope, is characterized beech-fur forest, meadows, deforestation (5 species Fij0). On the other hand the most specific biotope is the hornbeam-beech forest and firry forest (in all variants only 3 species from Fij0) in none of the species which gives the priority to this biotope, the index of the preference not bigger than Fij=0,60 (Myodes glareolus in the firry forest and Sylvaemus tauricus in the beech forest).

Thirdly, the number of populated mouse-like rodents in some of biotops is also not constant and on average each species occupies 71,4 % of available biotops. Top of your list by the number of biotops of the engaged Sylvaemus tauricus, Sylvaemus sylvaticus, Myodes glareolus and Microtus arvalis (100 %), followed in descending order follow Terricola subterraneus (85,7 %), Apodemus agrarius (71,4 %), Microtus agrestis and Mus musculus (by 57,1 %), Micromys minutus and Arvicola scherman (42,8 %). To some extent, number of biotops is populated species of formalized assessment and in general correlates with the total number trapped animals of a certain type, but this relationship is not straightforward. There are some species that are under similar levels of the relative the number occupied by opposite places on this list: eg., Sylvaemus sylvaticus (n=79) found in 77,8 % biotopes and Arvicola scherman (n=64) in 33,3%.

Fourthly it is obvious that the continuous one type forests which are considered to be the main species of the ecosystem of the Carpathian, they cant support the high level of the species rich of the small mammals. The high biotope preferences parts of species to meadows and log cabins (the latter can be regarded as analogues of windfalls) indicate that the high complexity of communities can be achieved only at the expense of small in size but specific to the area of ours research variants ecosystems, including forestless biotopes (firstly of the meadow type, secondy forestless).

Biotope preference of mouse-like rodents in the territory park analyzed. The character of using of this territory by the species and the connection between the species and biotops has been studied. Its settled Arvicola sherman is a stenotopos of species on the territory of the park which occurs only among meadow biotope. Micromys minutus, Mus musculus, Apodemus agrarius, Microtus agrestis are species which happen only here and there. Sylvaemus tauricus, Sylvaemus sylvaticus, Myodes glareolus Microtus arvalis can be met among all biotops in the park.

Our research found that within the limits of the park each species of mouse-like rodents has certain biotope preferences, which open their ecological features and determine the uniqueness, value and representativeness of the territories. In connection with high levels biotope preferences mouse-like rodents may be speciesindicators, absence / presence or number of an ecosystem which testifies to condition of these ecosystems.

They can also be as evaluative indicators which used to determine the value of the territory from the perspective of the protection of nature.

The mouse-like rodents can act as warning indicators of environmental disasters since the disappearance of their forest habitat in which they were distributed throughout the ages, shows excessive human pressure on the area. Mouse-like rodents can act as warning indicators of environmental disasters because the disappearance of their forest biotopes in which they were widespread throughout the ages testifies excessive anthropogenic pressure on this territory.

Key words: biotope, mouse-like rodents, biotope preference, stenotopos, here and there, evritopos of species.
