20.500.12556/RUL-161979 Povezava med prisotnostjo zveri in stanjem okolja Relationship between the presence of carnivores and the state of the environment Ljudje s svojim delovanjem vedno bolj onesnažujemo okolje, kar predstavlja globalni problem. Kot bioindikatorje predvsem za onesnaževanje z neesencialnimi mikrorudninskimi snovmi, lahko uporabimo zveri, kot so navadna lisica, evropski jazbec, rjavi medved, sivi volk, evrazijski ris in evrazijski šakal. Neesencialne mikrorudninske snovi se ne razgradijo, temveč se kopičijo v različnih tkivih in organih živali. Za analizo so primerne ledvice, jetra, možgani, zobje in dlaka. Analizirano tkivo izberemo na podlagi tega, katera rudninska snov se v tem tkivu oz. organu kopiči in s katero rudninsko snovjo je raziskovano območje onesnaženo. Običajno so to jetra, ledvice in možgani. Med zvermi so kot bioindikatorji ustrezne predvsem vsejede živali, saj zaužijejo tudi rastline, ki kopičijo posamezne rudninske snovi, nadalje se nato kopičijo v tkivih živali. Pri rezultatih so poleg izbire tkiva, vrste zveri in prehrane, pomembna tudi spol, starost ter sezona, v kateri smo živali ujeli oz. ji odvzeli vzorce tkiv oz. organov. Activity of human population results in an increasingly polluted environment, presenting a global problem. Carnivores such as the red fox, European badger, brown bear, grey wolf, Eurasian lynx and Eurasian jackal can be used as bioindicators, especially to monitor the pollution with non-essential micro-minerals. Non-essential microminerals are not degraded within animals but accumulate in animal tissues and organs. Kidneys, liver, brain, teeth and hair are suitable organs for micromineral analyses. Tissue or organ is selected for the analyses based on the mineral which is accumulating in it and based on the mineral which is contaminating the study area. These are usually the liver, kidney and brain. Among carnivores, the omnivores are particularly suitable as bioindicator spoecies, as they also consume plants which accumulate mineral substances which are then accumulated in their tissues and organs. In addition to the choice of tissue and organ, the species of carnivore and the diet, the sex, age and season in which the animal was caught or organs were sampled are also important factors. zveri bioindikatorji mikrorudninske snovi varstvo okolja carnivores bioindicators microminerals environmental protection true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-09-18 07:17:08 2024-09-18 07:17:11 2024-09-26 13:15:23 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 245655 208216323 42548.pdf 42548.pdf 1 780DE8E9DD7997704CB606F9F4AC6BDA 9b2b15aa1e27e9a8fea08ca42b8bda206d6b8a8f2516ac6255273b4f0c210bc0 272426e4-757d-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190989 Biotehniška fakulteta 0 0 0
