Abstract

Iako slatkovodne ekosustave čini svega 0,52 % ukupne vode na Zemlji, oni predstavljaju važno stanište mnogih biljnih i životinjskih vrsta. U ovom radu pobliže je opisan životinjski svijet slatkovodnih ekosustava. Oni se dijele na vode stajaćice i vode tekućice. Međusobno se razlikuju u raznim biotičkim i abiotičkim čimbenicima (primjerice morfološkim, hidrološkim i fizikalno-kemijskim obilježjima). Sukladno navedenim razlikama, sastav i struktura životinjskih zajednica pojedinih ekosustava se razlikuju. Također, ovisno u uvjetima kojima su izloženi u pojedinom ekosustavu, životinjski organizmi su razvili prilagodbe koje im omogućavaju opstanak i preživljavanje u istim. Od životinjskih organizama, vodena staništa naseljavaju kralješnjaci i beskralješnjaci. Od kralješnjaka, najbrojnije su ribe, dok su među beskralješnjacima često najbrojniji i najraznolikiji kukci. U ovom radu opisani su najznačajniji predstavnici navedenih skupina zastupljeni u slatkovodnim ekosustavima naše zemlje. Također, raspravljano je i o praktičnoj primjeni teme u razrednoj i izvanučioničkoj nastavi.

Abstract (english)

Although freshwater ecosystems account for only 0,52% of total water on Earth, they represent an important habitat of numerous plant and animal species. In this thesis, the most common animal communities of these ecosystems are described. Among freshwater ecosystems, lotic (flowing water) and lentic (standing water) habitats can be distinguished. They differ in various biotic and abiotic factors (such as morphological, hydrological and physico-chemical features). In accordance with these differences, the composition and structure of animal communities differ between ecosystems. Also, depending on the conditions animals are exposed to, they have developed various morphological, anatomical and behavioural characteristic that enable them more successful adaptation to their environment, and therefore higher chances of survival. Aquatic habitats are inhabited with various invertebrate and vertebrate animals. Among vertebrates, the most numerous are fish, while insect are 2 among the most numerous and diverse aquatic invertebrates. This thesis describes the most significant representatives of the mentioned animal groups represented in the Croatian freshwater ecosystems. Also, practical use of this the topic in the classroom and in the fieldwork-teaching was discussed.
