Abstract
Na razini slatkovodnih vodenih ekosustava, Daphnia magna je često u ulozi plijena kojim se hrane brojni predatori. Slatkovodni zooplankton, kojem pripada D. magna, pokazuje široki spektar strategija za obranu od predatora. U ovom radu cilj je istražiti i utvrditi mehanizme obrane, prilagodbe i preživljavanja velike vodenbuhe kao plijena zelenim hidrama, mnogookoj i šiljoglavoj puzavici u slatkovodnom mikrokozmosu te interakcije s prisutnim izoliranim endosimbiotskim algama. Cilj je i utvrditi mogućnost primjene ovog istraživanja u izvannastavnim aktivnostima iz biologije u srednjoj školi. Svaki pokus izveden je u pet replika pri 25 °C i 13,5 °C, i sa sitim i s gladnim životinjama, uz kontrole. Rezultati su pokazali da je u najvećoj mjeri prisutno grupiranje (vizualna magnifikacija) jedinki D. magna kao mehanizam obrane od predatorskih napada, a osim toga, uočena je pojava hiperprodukcije jedinki, ubrzano kretanje (“bullet”) te zarobljenost i bijeg iz mreže algi i sluzi. Anketnim istraživanjem utvrđeno je da je zastupljenost prirodoslovnog područja u izvannastavnim aktivnostima učenika zagrebačkih gimnazija relativno visoka te da su učenicima najatraktivniji sadržaji koji uključuju mikroskopiranje ili istraživački rad.
Abstract (english)
At the level of freshwater aquatic ecosystems, Daphnia magna is often in the role of prey that feeds on numerous predators. Freshwater zooplankton, to which D. magna belongs, shows a wide range of predator defense strategies. The aim of this thesis is to investigate and determine the mechanisms of defense, adaptation and survival of the large water flea as prey to green hydra and freshwater turbellarians in freshwater microcosm and interaction with the present isolated endosymbiotic algae. The aim is to determine the possibility of applying this research in extracurricular activities in biology in high school. Each experiment was performed in five replicates at 25 °C and 13,5 °C, with fed and hungry animals and controls. The results showed grouping (visual magnification) of D. magna individuals as the defense mechanism against predatory attacks, occurrence of hyperproduction of individuals, accelerated movement (“bullet”) and captivity and escape from a net of algae and mucus. The survey showed that the representation of the natural sciences in extracurricular activities of students in Zagreb grammar schools is relatively high and that the most attractive to students are contents that include microscopy or research work.
