Abstract

Istraživanje okućenih ameba provedeno je na acidofilnom cretu Đon močvar na pet postaja. Uzorci su se sastojali od cretnog tla i dijelova maha tresetara (Sphagnum spp.). Ukupno je zabilježeno 50 svojti okućenih ameba iz rodova: Arcella, Centropyxis, Cyclopyxis, Trigonopyxis, Quadrulella, Nebela, Paraquadrula, Plagiopyxis, Difflugia, Cryptodifflugia, Heleopera, Cyphoderia, Assulina, Euglypha, Sphenoderia, Tracheleuglypha, Trachelocorythion, Corythion, Trinema i Archerella. Detaljna morfometrijska analiza ljušturica u 260 jedinki vrste Trinema lineare i 35 jedinki vrste Trinema enchelys pokazala je veliku morfološku varijabilnost svih ispitivanih parametara. Zabilježene minimalne vrijednosti širine ljušturice i visine i širine oralnog otvora za T. lineare, te minimalne visine oralnog otvora u T. enchelys izlaze iz okvira vrijednosti zabilježenih u literaturi. U ovom radu prvi put su prezentirani rezultati mjerenja kuta nagiba oralnog otvora u ove dvije vrste. Vrsta T. enchelys pokazivala je puno veću varijabilnost kuta nagiba oralnog otvora od vrste T. lineare.

Abstract (english)

Testate amoeba research was done on acidophilic bog Đon močvar on five stations. Samples were made of bog soil and peat moss (Sphagnum spp.). Totally 50 taxa of testate amoebae was recorded comprising genera: Arcella, Centropyxis, Cyclopyxis, Trigonopyxis, Quadrulella, Nebela, Paraquadrula, Plagiopyxis, Difflugia, Cryptodifflugia, Heleopera, Cyphoderia, Assulina, Euglypha, Sphenoderia, Tracheleuglypha, Trachelocorythion, Corythion, Trinema, and Archerella.. Detail morphological analysis of 260 tests of Trinema lineare and 35 tests of Trinema enchelys showed a great morphological variability of all measured parameters. Minimal values of tests width and pseudostome width and height in T. lineare, and also minimal height of pseudostome in T. enchelys were out of the range of literature values for these species. Results of pseudostome angle measurements for these two species were presented for the first time. Species T. enchelys showed much bigger variability of pseudostom angle, than species T. lineare.
