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 ...
15 صفحه اولDecomposition of diverse litter mixtures in streams.
In view of growing interest in understanding how biodiversity affects ecosystem functioning, we investigated effects of riparian plant diversity on litter decomposition in forest streams. Leaf litter from 10 deciduous tree species was collected during natural leaf fall at two locations (Massif Central in France and Carpathians in Romania) and exposed in the field in litter bags. There were 35 s...
متن کاملMacroinvertebrate identity mediates the effects of litter quality and microbial conditioning on leaf litter recycling in temperate streams
Plant litter decomposition is an essential ecosystem function that contributes to carbon and nutrient cycling in streams. Aquatic shredders, mainly macroinvertebrates, can affect this process in various ways; they consume leaf litter, breaking it down into fragments and creating suitable habitats or resources for other organisms through the production of fine particulate organic matter (FPOM). ...
متن کاملEucalyptus plantations affect fungal communities associated with leaf-litter decomposition in Iberian streams
The replacement of diverse deciduous forests by eucalyptus plantations changes the timing, quality and quantity of litter inputs to streams, which has the potential to affect the activity of decomposers and thus ecosystem functioning. Here, we compared (a) the decomposition rate of alder and oak leaves incubated in deciduous and eucalyptus streams in Spain and Portugal, (b) the activity (fungal...
متن کاملLeaf Litter Mixtures Alter Microbial Community Development: Mechanisms for Non-Additive Effects in Litter Decomposition
To what extent microbial community composition can explain variability in ecosystem processes remains an open question in ecology. Microbial decomposer communities can change during litter decomposition due to biotic interactions and shifting substrate availability. Though relative abundance of decomposers may change due to mixing leaf litter, linking these shifts to the non-additive patterns o...
