Abstract
Nihajoča asimetrija (FA; le-ta predstavlja neusmerjene razlike med levo in desno polovico bilateralnih znakov, ki se zaradi različnih dejavnikov stresa ne morejo razviti v sicer genetsko določeni popolni simetriji) je lahko zelo dober odzivni bioindikator izpostavljenosti populacij različnim vrstam okoljskega oz. genetskega stresa. Kljub velikemu potencialu predstavljajo meritve FA v slovenskem prostoru domala neznano področje okoljskih raziskav. Zato so v prispevku podrobno predstavljeni: (a) najpomembnejši principi, prednosti in slabosti meritev FA; (b) novejše ugotovitve o vplivu dejavnikov stresa na velikost FA bilateralnih znakov različnih živalskih in rastlinskih vrst; (c) vpliv izpostavljenosti težkim kovinam na velikost FA izbranih znakovživalskih vrst; (d) dosedanje ugotovitve o asimetriji rogovja prostoživečih prežvekovalcev. Kot tak je prispevek pomemben za korektno, celovito in z dosedanjimi dognanji podprto predstavitev rezultatov lastnega dela na rogovju srnjakov, še zlasti za razumevanje uporabe FA rogovja kot odličnega pripomočka za bioindikacijo onesnaženosti okolja z anorganskimi onesnažili (spremljajoči prispevek).

Abstract:
Fluctuating asymmetry (FA), which reflects non-directional and stress-induced differences between the left and the right side of otherwise perfect symmetrical bilateral traits, may be a useful sensitive bioindicator of stressful conditions in many wildlife species. However, in spite of their great potential, FA analyses present an almost unknown research field in Slovenia. Therefore, the following issues are discussed at greater length in the paper: (a) the most important principles, advantages and drawbacks of FA analyses; (b) a review of recent findings on the influence of some stressors on FA of bilateral traits in different wildlife species; (c) influence of heavy metals on FA of selected animal traits/organs; (d) a review of existing findings on asymmetry of antlers/horns in wildliving ungulates. As such, this review paper is important for a well-grounded presentation of our own work on roe deer antlers, and particularly for understanding the employability of roe deer antlers as an excellent tool for bioindication of environmental pollutionwith inorganic pollutants (companion paper).

Keywords:fluctuating asymmetry, environmental stress, bioindication, antlers, deer, roe deer, wild-living ungulates
