Ecosystem of waters of Slnava
(Biology project)




I. Introduction


What is an ecosystem? It is a part of biome, where works a relationship between fauna, flora and their environment in particular area (e.g.: river, forest, meadow). All parts of ecosystem influence the other parts, and are –in response- being influenced by them. Plants, animals, bacteria work in an SYSTEM which is called ECOSYSTEM. My task in this work was to study any environment in area near my home and find some ecosystem which I can then examine and describe. I have chosen an area of water basin near the city Piešťany, I live in. It is called Sĺňava or Water basin Drahovce-Madunice. The reason why I have chosen this area is, that I live nearly 500 m far from this basin and for longer time I am interested in studying the animals and plants that live here. Piešťany is a small city situated in the upper end of Podunajská basin and they have temperate climate. Summers in this area are hot and that causes that many birds like storks, gulls, swans and sometimes also pelicans come to spend summer here. But in few last years it looks like people are no longer interested in nature and they are permanently destroying it. Also the water basin “lived a difficult ages” when sports and tourism developed and the area around the water basin was being destroyed because of indifference of some people. Nowadays is the water basin safe, because of support of people who defended nature like it is – unspotted from the modern world. It is officially said to be Protected study area Sĺňava. But people left here signs of their visits which cannot be deleted anymore. One of the is for example, that pelicans do not return to Piešťany after winter anymore. They were not safe from eyes of greedy tourists. I hope that my work about ecosystem of water basin Sĺňava will widen Your information about it and also teach some of you how important is it for the people, animals and plants that live in, by or around it. II. Method of work

First things I tried to do, was to find out as much information about Sĺňava, as I could. I tried to find information in our City Library, but there was not much to read, so I asked my friends and went to the basin to see the area I wanted to study. The best information I got, were from my uncle, who helped me to gain them from Balneology Museum Piešťany.
