Leaf breakdown and retention of four different sized leaf species in Rutanga Stream, Gombe Stream National Park, Tanzania
Introduction The relationship between terrestrial and aquatic ecosystems is particularly important in small, forested streams (Benfield 1996, Wallace et al. 1999). All stream organisms obtain their energy from either autochthonous sources such as photosynthetic algae or from allocthonous sources such as the surrounding riparian vegetation. Small, forested streams rely heavily on allocthonous in...

The transport and deposition of fine particulate organic matter (FPOM) is an important flux linking upstream and downstream reaches of stream ecosystems. However, few studies have attempted to identify physical controls on particle transport. One reason has been the lack of relatively simple, inexpensive methods. We describe a new technique for measuring fine particle transport in streams using...
متن کاملIn-Stream Nutrient Retention in Agricultural Catchments
In northeastern Austria, marshlands have been turned into the most productive arable land of the country. As a result, most headwater streams show structurally degraded channels, lacking riparian buff er zones, which are heavily loaded with nutrients from the surrounding crop fi elds. Th e present study examines whether longitudinally restricted riparian forest buff ers can enhance the in-strea...
متن کاملA/78A – Transport Stream Verification
This Recommended Practice provides a common methodology for describing Transport Stream conformance criteria. This RP explicitly describes the elements and parameters of A/53 and A/65 that should be verified in an ATSC Transport Stream for it to be considered a proper emission. It does not cover RF, captioning, or elementary streams.
