“…The RCC also predicts that shredders should be highest in relative abundance near the headwaters and decrease in relative abundance downstream, and that scrapers should reach their highest relative abundance in stream orders 3 and 4. Both of these predictions were confirmed by Bottorff and Knight (1989). Bottorff and Knight's (1989) study of the Cosumnes River Plecoptera also demonstrated that studies using immature, aquatic stages of benthic macroinvertebrates tend to underestimate species diversity.…”

“…Maximum species richness was between 3,500 and 4,900 ft above sea level. This altitudinal range corresponds to the third-and fourth-order reaches of the Cosumnes River where Bottorff and Knight (1989) also observed maximum species richness of Plecoptera. Don Burdick and Richard Gill (California State University, Fresno, written commun., 1992) reported 71 species of adult caddisfly collected between altitudes of 3,500 and 4,200 ft and 78 species between 4,200 and 4,900 ft.…”

FOREWORDThe mission of the U.S. Geological Survey (USGS) is to assess the quantity and quality of the earth resources of the Nation and to provide information that will assist resource managers and policymakers at Federal, State, and local levels in making sound decisions. Assessment of water-quality conditions and trends is an important part of this overall mission.One of the greatest challenges faced by waterresources scientists is acquiring reliable information that will guide the use and protection of the Nation's water resources. That challenge is being addressed by Federal, State, interstate, and local water-resource agencies and by many academic institutions. These organizations are collecting water-quality data for a host of purposes that include: compliance with permits and water-supply standards; development of remediation plans for specific contamination problems; operational decisions on industrial, wastewater, or watersupply facilities; and research on factors that affect water quality. An additional need for water-quality information is to provide a basis on which regionaland national-level policy decisions can be based. Wise decisions must be based on sound information. As a society we need to know whether certain types of water-quality problems are isolated or ubiquitous, whether there are significant differences in conditions among regions, whether the conditions are changing over time, and why these conditions change from place to place and over time. The information can be used to help determine the efficacy of existing waterquality policies and to help analysts determine the need for and likely consequences of new policies.To address these needs, the U.S. Congress appropriated funds in 1986 for the USGS to begin a pilot program in seven project areas to develop and refine the National Water-Quality Assessment (NAWQA) Program. In 1991, the USGS began full implementation of the program. The NAWQA Program builds upon an existing base of water-quality studies of the USGS, as well as those of other Federal, State, and local agencies. The objectives of the NAWQA Program are to:Describe current water-quality conditions for a large part of the Nation's freshwater streams, rivers, and aquifers.Describe how water quality is changing over time. Improve understanding of the primary natural and human factors that affect water-quality conditions. This information will help support the development and evaluation of management, regulatory, and monitoring decisions by other Federal, State, and local agencies to protect, use, and enhance water resources.The goals of the NAWQA Program are being achieved through ongoing and proposed investigations of 60 of the Nation's most important river basins and aquifer systems, which are referred to as study units. These study units are distributed throughout the Nation and cover a diversity of hydrogeologic settings. More than two-thirds of the Nation's freshwater use occurs within the 60 study units and more than twothirds of the people served by public water-supply syst...

“…Gasith & Resh 1999). In temporary streams, the main factors influencing the aquatic assemblages include the frequency and duration of the disturbance events and their predictability (Stanley et al 1997, Gasith & Resh 1999 , whether these streams are Alpine (Ruegg & Robinson 2004), karstic (Meyer et al 2003), prairie (Hill et al 1988, Miller & Golladay 1996, desert (Stanley et al 1997) or Mediterranean (Bottorff & Knight 1988, Touabay et al 2002, Beauchard et al 2003, Muñoz 2004. Generally, individual abundance and taxonomic richness and diversity were found to be greater in permanent than in neighbouring temporary streams (Williams 1996, Meyer & Meyer 2000, Touabay et al 2002, Muñoz 2004 and these values occasionally decreased with shorter presence of the water (Meyer et al 2003).…”

Perennial Oued Zegzel and temporary Oued Cherraa are parts of the same watercourse. Coinertia analysis showed the clear distinction between these two parts and the close relationship of the faunal assemblages with the characteristics of the water. The headwater course of the Zegzel is covered with dense terrestrial vegetation whose debris were consumed by abundant shredders dominated by the prosobranch Melanopsis praemorsa. The lower course of the Zegzel has sparse riparian vegetation and much fine detritus, and collectors such as Ecdyonurus rothschildi, Caenis luctuosa, the Diptera Corynoneurinae and Tanytarsini, occurred. In contrast, dry, flowing-, and standing-water periods succeed each other in the Cherraa and terrestrial vegetation often grows in its bed. M. praemorsa was replaced by the air-breathing pulmonate Physa acuta, accompanied by the adults and larvae of flying insects. However many shredders did not develop on the abundant plant litter. The short length of the submersion period was probably responsible for this lack of efficiency in the exploitation of such a non-limiting food resource.

Studies on the ecology of resource availability and its relation to hydrological regime are essential for aiding the understanding of stream functioning. This paper assesses the intrinsic role of potential food resources and hydrological variables in determining the functional structure of the macroinvertebrate community in a temporary, spring-fed stream. Quantitative estimates of food resources and aquatic macroinvertebrates, together with estimates of the hydrological variables, were collected during an annual surficial flow period. Standing stocks of benthic organic matter were moderately high (annual mean of 157.7 g AFDM m À2 ) and remained relatively constant over time. Moreover, allochthonous material was dominated by coarse material, reflecting the high retention but slow decomposition rates of Holm oak leaves, the major constituent of allochthonous inputs. Mean levels of periphyton biomass were high and decreased over the flow period (annual mean of 17 mg chl a m À2 ). The functional structure of the benthic macroinvertebrate community varied little over the study period and was consistently dominated by grazers and collectors. Conversely, predators and shredders were poorly represented and increased over the flow period. These observations were attributed to the impoverished invertebrate community that frequently characterizes temporary streams and the poor food quality associated with sclerophyllous leaf inputs at the beginning of the flow period. The small amplitude in discharge during most of the annual flow period and the high temperatures that distinguish the Mediterranean climate might allow algal food to be always available for consumers. This result may explain why autochthonous material was the most important food resource controlling food web dynamics in the studied temporary stream.
