Title: | The effect of temperature on leaf decomposition and diversity of associated aquatic hyphomycetes depends on the substrate | Authors: | Gonçalves, Ana Lúcia Graça, Manuel A. S. Canhoto, Cristina |
Keywords: | Fungal diversity; Litter quality; Stream ecosystems; Temperature | Issue Date: | 2013 | Publisher: | Elsevier Ltd and The British Mycological Society | Serial title, monograph or event: | Fungal Ecology | Volume: | 6 | Issue: | 6 | Abstract: | We examine the relative importance of substrate quality and temperature in the establishment of aquatic hyphomycete assemblages and in their ability to decompose leaves. We used leaves of alder (Alnus glutinosa) and oak (Quercus robur) and we tested four temperatures (5 , 10 , 15 and 20 C). Differences in decomposition rates and fungal assemblages were higher substrata than across temperatures. In both species, decomposition efficiency measured as the ratio of decay rate to fungal biomass, was greater at higher temperatures. Oak leaves were colonized by fewer aquatic hyphomycete species than was alder. Decomposition rates of oak increased with temperature but that of alder was not affected. We conclude that the substratum is a key driver of aquatic hyphomycete assemblages and can attenuate the effects of temperature differences on litter decomposition. | URI: | https://hdl.handle.net/10316/24967 | ISSN: | 1754-5048 | Rights: | openAccess |
