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 اولPresent 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...
متن کاملNonadditive effects of leaf litter species diversity on breakdown dynamics in a detritus-based stream.
Since species loss is predicted to be nonrandom, it is important to understand the manner in which those species that we anticipate losing interact with other species to affect ecosystem function. We tested whether litter species diversity, measured as richness and composition, affects breakdown dynamics in a detritus-based stream. Using full-factorial analyses of single- and mixed-species leaf...
متن کاملLitter breakdown and invertebrate detritivores in a resource - depleted Appalachian stream
We measured breakdown rates of leaves and small wood for the first three years in a stream in which detrital inputs were excluded for 7 years and in a reference stream located in the Appalachian Mountains of North Carolina, USA. Leaf and wood inputs were excluded using a gill-net canopy constructed over a 170-m section of stream. We hypothesized that red maple (Acer rubrum) and rhododendron (Rh...
متن کاملLitter 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...
