Describing and understanding the relationship between streamflow ecological processes is a classic problem in stream ecology river management. We applied individual-based model inSTREAM to describe dynamic habitat emergent population responses sympatric landlocked Atlantic salmon ( Salmo salar ) lake-migrating brown trout trutta ). This application explicitly describes environmental conditions ...

Abstract Leaf litter decomposition is a key process in stream ecosystems, the rates of which can vary with changes quality or its colonization by microorganisms. Decomposition streams increasingly used to compare ecosystem functioning globally, often requiring distribution across countries. It important understand whether sterilization, required some countries, alter and associated processes. W...

5 Parameter uncertainty and sensitivity analysis is especially important for large, complex 6 individual-based models intended to support management decisions. Yet these models are 7 difficult to analyze because they tend to have many parameters and long execution times. 8 We define a three-phase analysis strategy. Phase 1 examines model sensitivity to each pa9 rameter by itself. Phase 2 identi...

Local scour holes are erosional bed structures that related to different scientific disciplines in Earth science and hydraulic engineering. scouring at naturally placed boulders is ubiquitous, but many competing factors make it difficult isolate the effects of a given variable. This especially true for local natural instream obstacles exposed unsteady flow conditions course flood hydrograph exp...

Arctic freshwater ecosystems and fish populations are largely shaped by seasonal long-term watershed hydrology. In this paper, we hypothesize how changing air temperature precipitation will alter freeze thaw processes, hydrology, instream habitat to assess potential indirect effects, such as the change foraging behavioral ecology, on fishes, using Broad Whitefish Coregonus nasus an indicator sp...

label switching technology is a flexible and high performance method for forwarding layer three packets that are mapped to layer two flows. each label switch router, lsr, needs a specific label for every flow, where the number of labels depends on the mapping and granularity of flows. data and control driven methods are the most significant and popular methods in label mapping policy. the above...
