Abstract
Invazivne vrste ugrožavaju autohtone, te je njihov negativni utjecaj istaknut kao velika prijetnja globalnoj biološkoj raznolikosti. Invazivne vrste vodozemaca, ektotermnih organizama čija je tjelesna temperatura uvjetovana okolinom, ekstremno su osjetljive na promjene abiotičkih čimbenika u okolišu koji uvelike utječu na uspješnost kolonizacije područja invazivnom vrstom. U ovom radu proučavana je lokomotorna izvedba invazivne vrste žabe, afričke pandžašice Xenopus laevis. Istraživanje je provedeno na jedinkama vrste koloniziranog teritorija sjeverozapadne Francuske 2016. godine. Lokomotorno kretanje jedinki populacija s rubnog i centralnog dijela koloniziranog staništa testirano je u različitim temperaturnim uvjetima. Opažena je značajna razlika u lokomotornoj izvedbi dvaju populacija samo pri visokoj temperaturi što ukazuje na prilagodbu populacija vrste Xenopus laevis hladnijim temperaturnim uvjetima u Francuskoj gdje se nalaze već generacijama. Lokomotorna izvedba se razlikovala i s obzirom na spol jedinki, što je u skladu s dosadašnjim istraživanjima vrste gdje se mužjaci generalno uspješnije kreću. Dobiveni rezultati ukazuju na kompleksnost temperaturnih učinaka na fiziološke procese ektotermnih životinja, te da je vrsta vjerojatno sposobna kolonizirati šira područja.
Abstract (english)
Native species are frequently endangered by invasive species whose negative impact is widely recognized as a threat to global biodiversity. Amphibian invasive species are extremely sensitive to temperature variations, as they are ectothermic organisms whose body temperature is dependent on the temperature of the environment which greatly affects their capability to colonize new habitats. Locomotor performance of the invasive frog Xenopus laevis was studied in this research. The study was conducted in 2016 on individuals taken from the invaded northwestern territory of France. Populations from the periphery and the center of their invasive range were tested for locomotion at different temperature conditions. Significant dfference between populations in locomotor performance was noticed only at higher temperature conditions, implicating that populations have adjusted to colder temperature conditions in France where they have been introduced generations ago. Locomotor performance differed according to sex of the individuals, in accordance with other research on this species with males being generally better performers. Given results demonstrate the complexity of how temperature affects the physiological processes in ectotherms and indicate even more successful colonization of this invasive species.
