Meiofauna promotes litter decomposition in stream ecosystems depending on leaf species

survey microbial decomposition leaf litter of salix sp. populus sp. robinia sp. in artificial stream

مطالعه اکولوژیک از سرچشمه رودخانه قره سو(سراب روانسر) در استان کرمانشاه واقع در غرب ایران در پائیز 1378 انجام شد، حداکثر دمای آب 20 درجه سانتی گراد بود، هنگام مطالعه دما در سرچشمه 18 سانتی گراد بود، مقدار عناصر شیمیایی آب اندازه گیری نشد. در این پژوهش لاشبرگ های درختی از بید، چنار، اقاقیا جمع آوری سپس توسط بخش هرباریوم دانشکده کشاورزی دانشگاه شناسایی شدند. وزن خاکستر خشک afdm در(نمونه برداری ...

Present Effects of Past Wildfires on Leaf Litter Breakdown in Stream Ecosystems

—We investigated the present effects from a 10-year-old wildfire on leaf litter breakdown rates in 3 headwater streams in central Idaho. These systems experienced a massive debris flow one year after the fire. Based on soil instability and burn patterns, we identified 3 stream conditions: unburned, burned only, and burned/scoured. We placed leaf bags containing willow leaves (Salix sp.) in each...

Leaf diversity influences in-stream litter decomposition through effects on shredders

Litter Breakdown and Microbial Succession on Two Submerged Leaf Species in a Small Forested Stream

Microbial succession during leaf breakdown was investigated in a small forested stream in west-central Georgia, USA, using multiple culture-independent techniques. Red maple (Acer rubrum) and water oak (Quercus nigra) leaf litter were incubated in situ for 128 days, and litter breakdown was quantified by ash-free dry mass (AFDM) method and microbial assemblage composition using phospholipid fat...

VI. Decomposition of Different Leaf Species Invertebrate and Microbial Colonisation in Native and Exotic Leaf Litter Species in a Mountain Stream

Decomposition of three leaf species (Alnus glutinosa, Eucalyptus globulus and Quercus robur) were examined in a headstream. During two months decomposing leaves were periodically analysed for nutrient content, soluble sugars, phenols, protein precipitation capacity, total fiber, weight loss, microbial and macroinvertebrate colonisation. The leaves of the three species showed similar patterns in...
