Water temperature effects of the decomposition rate of leaf litter Abstract: Fall of leaves represents and important energy source for many aquatic ecosystems, especially in headwater streams and forest lakes. The fluctuation of water temperature and precipitations directly affect the growth of fungi and leaf litter decomposition. From January 2014 till August 2014 litter bag method was used to investigate the decomposition of three types of leaf litter (Salix alba, Alnus glutinosa and Populus sp) in three different locations with different water temperature (Kétöles-patak 1,7-21,5 °C , Tapolca-patak at Raposka 9,6- 21 °C, Tapolca-patak at Tapolca 15,2- 22,3 °C). In our investigations two different mesh sized bags were used (3 mm and 100 pm mesh size): the fine- mesh bags were used to determine the weight loss from the microbial decomposition. The examined litter species belonged into rapid decomposition category in all sampling sites in both litter bag types. The ergosterol concentration maxima were reached in the medium-temperature sampling site for all leaf types.
