Abstract
Zagađenje i invazivne strane vrste su jedni od glavnih čimbenika antropogeno uvjetovanih promjena u okolišu. Cilj ovog rada bio je istražiti kako farmaceutici prisutni u rijeci Savi, antidepresivi citalopram i nortriptilin te opojna droga amfetamin, utječu na antagonističko ponašanje najuspješnije invazivne strane vrste rakova u Europi, signalnog raka (Pacifastacus leniusculus). Agresivnost odnosno antagonističko ponašanje jedna je od ključnih odrednica invazivnog uspjeha signalnog raka. Tijekom 7 dana, rakovi su izlagani terapeutskoj (visokoj) ili okolišno relevantnoj (niskoj) koncentraciji odabranih farmaceutika. Za potrebe istraživanja antagonističkog ponašanja, jedinke podjednakih veličina stavljene su u parove koji su bili miješani (jedna jedinka u paru izložena spoju, a jedna kontrola) ili kontrolni (obje jedinke u paru kontrole). Snimanje antagonističkog ponašanja odvijalo se nakon 24 sata i nakon 7 dana izlaganja. Zabilježeni parametri ponašanja su: trajanje i broj borbi, vrijeme proteklo do prve borbe te identitet pobjednika i inicijatora borbi. Rezultati pokazuju da odabrani farmaceutici ne utječu na vrijeme proteklo do prve borbe te na dominaciju izloženih rakova u antagonističkim interakcijama. Međutim, izlaganje rakova visokim koncentracijama svih odabranih farmaceutika i niskoj koncentraciji amfetamina mijenja dinamiku antagonističkih interakcija na način da smanjuje broj i duljinu trajanja borbi u usporedbi s kontrolom.
Abstract (english)
Pollution and invasive alien species are one of the main factors of anthropogenically induced environmental changes. The aim of this study was to examine whether pharmaceuticals present in the Sava River, antidepressants citalopram and nortriptyline, and illicit drug amphetamine could have an effect on behaviour of the most successful crustacean invader in Europe, signal crayfish (Pacifastacus leniusculus). Agonistic behaviour is one of the key determinants of invasive success of signal crayfish. Crayfish were exposed to environmentally relevant (low) or therapeutic (high) concentration of selected pharmaceuticals for 7 days. For analysis of agonistic behaviour, equal size individuals were placed in mixed pairs (one individual was exposed and the other was a control) or control pairs (both individuals were controls). Agonistic behaviour was recorded after 24 hours and 7 days of exposure. Recorded behavioral parameters included: duration and number of fights, time to first fight, identity of the winner and initiator of fights. Results show that selected pharmaceuticals have no effect on time to first fight or on dominance of exposed crayfish in agonistic interactions. However, exposure of crayfish to high concentrations of all selected pharmaceuticals and low concentration of amphetamine reduced the number and duration of fights compared to control.
