Primary Productivity in Streams,(1982) discuss communications of Minshall and Fisher and point out that a system may shift from being annually accretive to remissive depending on flood flows and channel conditions that affect storage capability.

Succession in Streams,Early phytosociologists such as Cowles (1901), Clements (1916), and Gleason (1926) viewed succession exclusively as temporal change in terrestrial plant communities. Drury and Nisbet (1973) recently emphasized that successional ideas have been derived from and tests should be restricted to temperate

Density Independence Versus Density Dependence in Streams,sic structure of stream communities and the life histories of some component species have been worked out. Enough information has now been amassed for researchers to examine functional relationships within the stream community. The formalization of the functional group concept (Cummins, 1974), the R

Use of Behavioral Experiments to Test Ecological Theory in Streams,riptions of stream insect behavior were usually qualitative but of masterful literary style. Needham et. al. (1935) indulged in countless flowery descriptions of mayfly behavior, for example, this description of activities of close-clinging, stone-loving mayfly nymphs: “Under the stones we may find

The Importance of Competitive Interactions Within Stream Populations and Communities, a growing science, it will become increasingly important to know what role competitive interactions play in producing patterns within natural populations and communities. In this review, I consider some of the evidence suggesting the relative importance of such competitive interactions within strea

Competition, Colonization Patterns, and Disturbance in Stream Benthic Communities, coexistence of the member species. The richness and complexity of benthic communities in streams has long been recognized but very few factors that influence these patterns are understood, A hierarchy of mechanisms responsible for the distribution and abundance of organisms exists within any commun
