The Riverine Ecosystem Synthesis Toward Conceptual Cohesiveness in River Science pptx

[...]... continuum concept RES: riverine ecosystem synthesis RPM: riverine productivity model Floodscape (an original term): The aquatic and terrestrial components of the riverine landscape that are connected to the riverscape only when the river stage exceeds bankfull (flood stage) These include the terrestrial floodplain (including components of the riparian zone not in the riverscape) and floodplain water bodies,... cohesiveness in the field of river science The RES specifically brings together concepts and paradigms from the disciplines of landscape ecology, lotic ecology, and fluvial geomorphology BASIC CONCEPTS IN THE RIVERINE ECOSYSTEM SYNTHESIS Many prominent riverine theories, such as the River Continuum Concept (RCC; Vannote et al., 1980) and the FPC (Junk et al., 1989), have included diverse ecological and theoretical... general riverine theory is the heuristic Riverine Ecosystem Synthesis (RES; Thorp et al., 2006) As summarized in the current chapter, the RES is an integrated model derived from aspects of other aquatic and terrestrial models proposed from 1980 to 2007, combined with our perspectives on functional process zones (FPZs) and other aspects of riverine biocomplexity The RES pertains to the entire riverine landscape,... designing and implementing a sample scheme for monitoring and bioassessing a riverine ecosystem If this person views the river as a continuum, then the sampling program might be based on a longitudinally stratified, random sample design In contrast, if the riverine ecosystem is composed of large hydrogeomorphic patches (e.g., our FPZs), as we and others are increasingly proposing, then startlingly...
