Abstract

Glavni cilj ovog rada bio je utvrditi morfološke značajke i metodom ICP-AES odrediti
kemijski sastav kućica slatkovodne vrste H. holandrii te utvrditi razlike i sličnosti u
mjerenim vrijednostima. Ukupno je analizirano osam populacija, šest iz Hrvatske i dvije iz
Srbije. Uzorci su prikupljeni ručno u periodu od 2008. do 2016. godine. Iz svake populacije
nasumično je odabrano 30 odraslih jedinki kojima su napravljena morfometrijska mjerenja,
a njih 10 podvrgnuto je kemijskoj analizi. Rezultati morfometrijskih mjerenja pokazali su da
jedinke iz Cetine imaju najniže srednje vrijednosti svih značajki dok su jedinke iz Korane
imale najviše srednje vrijednosti visine kućice, ušća i zavojnice. Iz omjera morfometrijskih
značajki vidljivo je da se kućice puževa iz Maje i Cetine najviše razlikuju od ostalih.
Vrijednosti Pearsonovog koeficijenta korelacije ukazuju da je većina omjera statistički
značajno međusobno srednje povezana te su ti omjeri međusobno proporcionalni. U
otopinama uzorka utvrđen je sadržaj ukupno dvanaest kemijskih elemenata. Multivarijatnom
analizom utvrđena je elementna podjela glavnih komponenata na dvije skupine dok je
klasterskom analizom ustanovljena najveća sličnost između populacija uzorkovanih u Kupi
i Uni, a populacije puževa iz Maje i Drine najviše se razlikuju od ostalih.

Abstract (english)

The main objective of this activity was to determine the morphological features and with
ICP-AES method determine the chemical composition of the shell of the freshwater snail H.
holandrii and to identify similarities and differences in the measured values. Eight
populations were analyzed all together, six from Croatia and two from Serbia. Samples were
collected manually in the period from 2008. to 2016. Of each population, randomly, 30
adults individuals were selected and morphometric characteristics of the shell shape were
measured. Ten were subjected to a chemical analysis. The results of morphometric
measurements have shown that Cetina individuals have the lowest mean values of all
features, while the Korana individuals had the highest mean values shell length, aperture
length and hight spire. From the morphometric aspect ratio it is apparent that the snail from
Maja and Cetina differ most from the rest. Pearson correlation coefficient indicated that most
of the ratios are statistically significantly interrelated and these proportions are proportional
to each other. The sample solution contained the contents of twelve elements. Multivariate
analysis determined the basic division of the main components into two groups, while the
cluster analysis showed the highest similarity between population collected at the sites of the
Kupa and Una, the population of snails from Maja and Drina differed most from others.
