Analiza telesnih kazalcev in gostote jelenjadi v LPN Jelen Snežnik : diplomsko delo - univerzitetni študij

Bajec, Marko (author), Jerina, Klemen (mentor)

V nalogi smo za obdobje 1976%2005 preučevali odzive telesnih kazalnikov jelenjadi glede na številčnost jelenjadi, ki je določenega leta poseljevala območje LPN Jelen Sneţnik. Telesni kazalci, ki smo jih analizirali, so telesna masa ločeno po spolu in starostnih kategorijah za vse osebke, pri odraslih jelenih smo analizirali še maso rogovja in število CIC točk rogovja. Populacijsko gostoto smo rekonstruirali s pomočjo povratnega računanja iz podatkov, dobljenih iz evidenc odvzete jelenjadi. Rezultati so pokazali, da se je številčnost populacije gibala od 5,8 pa do 2,6 osebka na 100 hektarjev. Analize kaţejo, da populacijska gostota ni statistično značilno vplivala na telesno maso telet in enoletne jelenjadi. Pokazal pa se je vpliv populacijske gostote na telesno maso odrasle jelenjadi in to pri obeh spolih. Pri analizi vplivov na maso rogovja in število CIC točk rogovja smo ugotovili, da nanju pozitivno vplivata višja starost in višja telesna masa, negativno pa nanju vpliva populacijska gostota.

• Title: Analysis of body indicators and population density of red deer in LPN Jelen Snežnik

Abstract

In this graduation thesis we were analyzing body indicators of red deer in the area of LPN Jelen Sneţnik, depending to population density in the period from 1976 to 2005. Analyzed body indicators are: body mass separated by sex and age category for all individuals, for adult male we analyzed also antler mass and CIC points of antler. Population density was reconstructed using reverse calculation, from data obtained from year harvesting. The results showed that the population density varied from 2,6 up to 5,8 individuals per 100 hectares. Analysis show that population density do not statistically significant influence the body weight of deer calves and yearlings. On the other hand we found statistically significant influence of population density on body weight for both sex of older animals. In analyzing the effects on antler weight and number of antler CIC points, we found a positive influence on them by older age and higher body weight, but they were influenced negatively by population density.
