Incorporating Episodicity into Estimates of Critical Loads for Juvenile Salmonids in Scottish Streams
Critical Load (CL) methodology is currently used throughout Europe to assess the risks of ecological damage due to sulphur and nitrogen emissions. Critical acid neutralising capacity (ANC CRIT) is used in CL estimates for freshwater systems as a surrogate for biological damage. Although UK CL maps presently use an ANC value of 0 meq l 1 , this value has been based largely on Norwegian lake stu...
متن کاملSummer movement and growth of juvenile anadromous salmonids in small western Washington streams
Ahstmct: Movements of juvenile coho salmon (Oncorhynrhu,~ kisutch), cutthroat trout (Oncorhynchus clarki clarki), wd steelhead trout (Oncorhynchus mykiss) were studied by observalions and rccapturc of marked individutlls in three western Washington streams to test the hypotheses that few fish would move, downstream movement would predominate, movers would be initially smaller and grow slower af...
متن کاملTime, space, and episodicity of physical disturbance in streams
Storm-driven episodes of gully erosion and landsliding produce large influxes of sediment to stream channels that have both immediate, often detrimental, impacts on aquatic communities and long-term consequences that are essential in the creation and maintenance of certain channel and riparian landforms. Together, these effects form an important component of river ecosystems. In this paper we d...

Incorporating Uncertainty into Time-geographic Density Estimates
Time geography provides a rigorous mathematical framework for analysing movement patterns of mobile objects (Hagerstrand 1970, Miller 2005a). Given a set of tracking data, the fundamental elements of time geography—the space-time path and space-time prism—can be used to delimit the possible movements of an object between observed data points. This basic approach has proven useful in a number of...
