Yeast and macroinvertebrate communities associated with leaf litter decomposition in a second order stream
| Resumo: | The composition of yeast and macroinvertebrate communities was studied on black alder, blue gum eucalyptus and English oak leaves decaying in a stream during a six‐month period. ANOVA analysis showed significantly different values (p < 0.0001) of yeast and macroinvertebrate densities among the three leaf litters. Some yeast species such as Cryptococcus albidus (Saito), C. laurentii (Kufferath), Rhodothorula glutinis (Fresenius), R. colostri (Castelli), and Debaryomyces hansenii (Lodder and Kreger‐van Rij) were present in all litter types. Other yeasts were restricted to a specific type of litter. Macroinvertebrates were dominated by collectors‐gatherers on oak and eucalyptus leaves. Shredders reached highest densities in alder leaves. |
