Abstract
Pojavljivanje vrste Mytilus galloprovincialis kao i njena morfologija uvjetovani su brojnim okolišnim čimbenicima. Glavni ciljevi rada bili su odrediti varijabilnost fluktuirajuće asimetrije 12 morfoloških obilježja ljušture između 15 nativnih populacija vrste M. galloprovincialis te utvrditi povezanost fluktuirajuće asimetrije i fitnesa. U svrhu utvrđivanja varijabilnosti fluktuirajuće asimetrije analizirano je 300 jedinki nativnih populacija (20 po populaciji). Kako bismo procijenili fitnes jedinki te povezanost fluktuirajuće asimetrije i fitnesa 900 jedinki jedne populacije smo podvrgnuli transplant eksperimentu i preživljavanju na zraku u „stres na stres“ (SOS) testu. Najveća asimetrija zabilježena je za udaljenost od plaštene linije do ventralnog ruba ljušture – PAL, te obilježja povezana sa stražnjim mišićima aduktorom i retraktorom, pri čemu najveća za širinu otiska stražnjeg mišića retraktora - WPR. „Stres na stres“ metodom utvrdili smo da dagnje prethodno izložene čistim postajama imaju kraće preživljavanje od dagnji na onečišćenim postajama. Korelacije fluktuirajuće asimetrije i preživljavanja na zraku kod jedinki prethodno izloženih različitom stupnju onečišćenja utvrdili smo za dagnje izložene na četiri od šest postaja, pri čemu dvije čiste postaje Zadar Seline - ZBT i Ston - SUT nisu pokazale navedene korelacije.
Abstract (english)
The distribution of the species Mytlus galloprovincialis and its morphology are determined by numerous environmental factors. This study main objectives were to determine the variability of fluctuating asymmetry for 12 shell’s morphological characteristics on 15 native populations of the species M. galloprovincialis and to identify the correlation between fluctuating asymmetry and fitness. For the purpose of identifying the variability of fluctuating asymmetry, 300 specimens of native populations (20 per population) were analyzed. In order to assess the fitness of specimens and relationship between fluctuating asymmetry and fitness, we submitted 900 specimens of a population to transplant experiment and survival in the air in "stress on stress" (SOS) responsive test. The maximum asymmetry is registered for distance from the mantle line to the ventral edge of the shell – PAL and traits related to posterior adductor and retractor muscles, where the highest asymmetry is registered for the width of the posterior retractor muscle – WPR. Through SOS test we identified that mussels previously exposed to less polluted sites live shorter than the mussels exposed on polluted sites. We identified correlations between fluctuating asymmetry and survival in the air in specimens previously exposed to different levels of pollution for mussels exposed to four out of six sites, where two less polluted sites Zadar Seline – ZBT and Ston SUT – showed no previously stated correlation.
