Abstract

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.

Leaf decomposition, an important component of the organic matter dynamics in streams, has been widely examined in temperate regions but much less documented in tropical regions. We report here the first study of leaf decomposition in a Sri Lankan stream. The litterbag technique was used. Coarse (8 m

Macroinvertebrate communities were studied in relation to food (particulate organic matter and periphyton) availability and hydrologic regime in two reaches (autotrophic and heterotrophic) of the Aguera stream (Northern Spain). The structure of macroinvertebrate community reflected the trophic chara
