What is Leaf Decomposition in a Mountain Stream in the Sultanate of Oman about?

## Abstract Decomposition of __Juglans regia__ leaves was studied in fine and coarse mesh bags in a permanent mountain stream in Oman. A rapid initial mass loss, attributed to leaching, was followed by a more gradual decline. Daily exponential decay rates (k) calculated over 32 days were 0.011 (fine mesh litter bags) and 0.014 (coarse mesh litter bags). The difference between bag types was not significant, suggesting limited impact of leaf‐shredding invertebrates. Ergosterol levels on leaves from fine mesh bags peaked at 0.3 mg g^–^^1^ AFDM after 16 days of stream exposure. During the experimental period, which followed the annual leaf fall, the concentration of aquatic hyphomycete conidia in the stream varied between 82 and 1362 l^–1^. Based on the morphology of conidia found in the water column or released from leaves, we identified 14 species of aquatic hyphomycetes. __Tetracladium apiense__ was the most common taxon (62.2% of conidia in water column during the field experiment). Three other __Tetracladium__ species contributed another 8%. Plating out leaf particles yielded common epiphytic taxa such as __Alternaria__ sp., __Aureobasidium pullulans__ and __Phoma__ sp. The measur
