Abstract
Morfologija školjkaša je uvjetovana genetskim i okolišnim čimbenicima. Glavni cilj ovog rada bio je utvrditi fitnes populacije dagnji vrste Mytilus galloprovincialis, izložene 4 tjedna na 6 lokacija u okolišima različitog stupnja onečišćenja i njegovu uvjetovanost morfološkima obilježjima i fluktuirajućom asimetrijom. Tijekom stres na stres testa dagnje izložene na postajama nižeg stupnja onečišćenja su preživljavale kraće nego one izložene na postajama višeg stupnja onečišćenja. Prikupljeni su podaci za 13 morfometrijskih obilježja mjerenih na ljušturama 900 jedinki. Utvrđena je korelacija širine i fitnesa, pri čemu su uže dagnje preživljavale dulje, neovisno o stupnju zagađenja okoliša. Utvrđeno je da su dagnje prethodno izložene čistim postajama preživljavale dulje ukoliko su imale manji volumen i veću duljinu otiska stražnjeg mišića aduktora, a preživljavanje dagnje izloženih onečišćenim postajama koreliralo je s pozicijom stražnjeg mišića retraktora. Najmanja fluktuirajuća asimetrija zabilježena je za visinu ljušture, a najveća za svojstva vezana uz stražnji mišić retraktor. Veća asimetrija udaljenosti od trbušnog ruba stražnjeg mišića retraktora do leđnog ruba ljušture korelirala je s boljim fitnesom dagnji izloženih na čistim postajama. Ovo istraživanje pokazalo je povezanost fitnesa i određenih morfoloških obilježja dagnje, kao i njenu okolišnu uvjetovanost.
Abstract (english)
The morphology of bivalves is a combined result of genetic and environmental factors. The main objective of this study was to determine the relationship between fitness and morphometric traits in a Mytilus galloprovincialis population, exposed at 6 locations in the environments of differing degrees of pollution. Mussels exposed to polluted environments survived longer in stress on stress response test. Data were collected on 13 shell morphological traits for 900 individuals. Shell width correlated with better survival irrespective of the environment the mussels were exposed to. Smaller volume and longer posterior adductor muscle scar increased the survival of mussels that were preexposed to environments of lower anthropogenic pollution, and position of the posterior retractor muscle correlated with the survival of the mussels exposed in polluted environments. Shell height exhibited lowest degree of fluctuating asymmetry, and the traits related to posterior retractor muscle the highest. Higher asymmetry of VPR – a trait related to posterior retractor position correlated with longer survival in mussels exposed to the environments of lower anthropogenic pollution. This study showed correlation between particular morphological traits and fitness of the Mediterranean mussel that was also environmentally conditioned.
