Population Dinamics of Woodland Rodents in Croatia pdf HR EN | 599 | |
Summary: Mouse and vole species, due to the population numerousness and width of the ecological valence, have been an important part of any forest ecosystem. By a continuous following of dynamics of their population it is possible to prevent their harmful activities on natural progeny, seeds, plants and spreading of certain zoonoses (trichinosis, leptospirosis, tick encephalitis, Lyme disease, haemorrhagic fever with kidney syndrome, etc.)Following the numerousness and population dynamics of small rodents on the terrain, analysing the population structure of certain species and determining the intensity of damages on seeds and young plants, conclusions are brought and protection measures are recommended in order to decrease their harmfulness in forest ecosystems. Regular following of small rodent populations on the terrain results in the timely prediction of period in which their excessive number can occur. Since small rodents have extremely high biological potential, in favourable years they appear in a huge number of populations when they do big damages. Then, a forest operative carries out protection measures which are most frequently done by chemical agents. In the period from September 1999 till June 2003, the number of small rodents was followed on 17 sites in Croatia. Animals were sampled in 10 forest communities with “Y” method, standard minimum method and the linear transect method. 2 151 individuals were caught. By all the methods there were 27 598 traps/night. At most of the sites, the following species were most present: Clethrionomys glareolus Schr., Apodemus agrarius Pall and A. flavicollis Melch. In a forest community Carpino betuli-Quercetum roboris typicum R. the smallest number of small rodents was calculated by a linear regression method (p = 0.05) in April, 2003 (N/ha = 11.63), and the greatest in March 2001 (N/ha = 82.03). On the same site, the number of the small rodent population was calculated by “Y” method in spring 2001 of 101.34 individual/ha. It was established that the number of small rodent population significantly depends on the forest seed crop. The average values of mice and voles catch were established by a method of linear transect in pedunculate oak forests (Quercus robur L.) in 44.70 % traps of set transects (October, 2000, site Velika Gorica) and in common beech forests (Fagus sylvatica L.) in 58,70 % traps (March 2002, site Nova Gradiška).
