20.500.12556/DiRROS-7603 Nihajoča asimetrija rogovja srnjakov (Capreolus capreolus L.) kot kazalec onesnaženosti okolja in pripomoček za upraljanje s populacijami Na 282 rogovjih srnjakov, uplenjenih v obdobju 1961 - 2002 v Šaleški dolini, smo določili nihajočo asimetrijo (FA; neusmerjene razlike med levo in desno stranjo) devetih bilateralnih morfoloških znakov. Ugotovili smo: (a) za analize FA je primernih pet znakov (dolžina veje, dolžina prednjega in zadnjega parožka, skupna dolžina veje, premer nastavka), ki ustrezajo potrebnim statističnim pogojem; (b) za vse znake obstaja pozitivna soodvisnostmed velikostjo in asimetrijo, zaradi česar FA rogovja ni primeren kazalec kakovosti posameznih osebkov; (c) lanščaki (zaradi nedokončanega telesnega razvoja asimetrija njihovega rogovja ni ustrezen kazalec onesnaženosti) imajo značilno večjo FA kot odrasli srnjaki; (d) FA je po letu 1980 upadala in je bila po izgradnji razžveplalne naprave na TEŠ manjša kot pred njo; (e) na ravni generacij obstaja značilna pozitivna soodvisnost med povprečnimi vsebnostmi Pb v rogovju in povprečno FA, kar kaže, da je onesnaženost okolja eden najpomembnejših dejavnikov stresa, ki vpliva na razvojno stabilnost procesa tvorbe rogovja. Fluctuating asymmetry (FA), which represents non-directional differences between the left and the right side, was measured for nine bilateral traits inthe antlers of 282 roe deer, shot in the period 1961 - 2002 in the Šalek Valley. Our findings were as follows: (a) Five traits (antler length, length of both front and back tine, total beam length, and pedicle diameter) are suitable for FA analyses, since they fulfil the necessary statistical criteria. (b) A significant positive correlation between size and asymmetry exists for all traits; therefore, roe deer antler asymmetry does not reflect the quality of an individual. (c) Yearlings, whose antler asymmetry is not a suitable bioindicator of environmental pollution due to an incomplete ontogenetic development, have significantly higher FA in comparison with adults. (d) In the Šalek Valley, roe deer antler FA has been decreasing since 1980; after the construction of the desulphurization device in the Šoštanj Thermal Power Plant it is significantly lower in comparison with the period before construction. (e) On the generation level, there is a significant positive correlation between mean Pb levels in antlers and their mean FA, which identifies environmental pollution as one of the main stressors causing deviation from bilateral symmetry of deer antlers. nihajoča asimetrija rogovje srnjad retrospektivni biomonitoring onesnaženost okolje svinec Šaleška dolina Termoelektrarna Šoštanj fluctuating asymmetry antlers roe deer historical biomonitoring pollution lead Šalek valley Šoštanj thermal power plant true false true Slovenski jezik Ni določen Znanstveno delo 2017-07-12 09:18:32 2017-07-12 09:18:32 2022-08-12 14:05:42 0000-00-00 00:00:00 2004 0 0 str. 5-40 Vol. 74 2004 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*149--013:181.45+120(045) 0351-3114 URN:NBN:SI:doc-BAQZFX5Q 1323430 6206978 RAZ_Pokorny_Bostjan_i2004.pdf RAZ_Pokorny_Bostjan_i2004.pdf 1 7183C3A5E781CA588C391372DDFC9717 16e83a0b2ffa1d9a2b2766f344df65056ba194cc6a655ac5407e1b9fe15859fa 1cb59ee7-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/6d316eea-f16b-4313-8873-1cac750f21e9 https://dirros.openscience.si/Dokument.php?lang=slv&id=9470 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
