The macroinvertebrate community was studied in 3 reaches along a north-Iberian stream that differ in the amount and nature of food resources. Regardless of shading and water quality, both invertebrate density and biomass were higher at the 2 downstream sites than at the headwater site. The taxonomic composition and functional organization of the faunal assemblages showed clear differences among sites: shredders and gatherers dominated the headwater site, and scrapers or gatherers, depending on the degree of shading and organic pollution, dominated the downtream sites. Macroinvertebrates responded roughly to intersite differences in food resources, but poor relationships between temporal dynamics of shredder or scraper abundance and that of their food were found. Likewise, no clear effect of floods on invertebrate density and biomass was observed.

“…Only in eight articles were data presented in a way that made further analysis possible (Cao et al, 1996;Kay et al, 1999;Hall et al, 2001;Marchetti and Moyle, 2001;Sponseller et al, 2001;Bojsen and Jacobsen, 2003;Camargo et al, 2003 andBruns, 2005), but studying these resulted in only a few data points. Because some articles dealt with macroinvertebrate families and others covered genera or species, it was not possible to combine these studies.…”

ABSTRACT1. A major threat to freshwater taxon diversity is the alteration of natural catchment Land use into agriculture, industry or urban areas and the associated eutrophication of the water. In order to stop freshwater biodiversity loss, it is essential to quantify the relationships between freshwater diversity and catchment Land use and water nutrient concentrations.2. A literature survey was carried out on biodiversity data from rivers and streams. Fish and macroinvertebrates were selected as focal groups as they are widely used as indicator species of river and stream health. Only published data were selected that (a) compared data found at impaired sites with a pristine reference situation (either in time or space), (b) clearly defined the stressors studied (Land use cover and/or nutrient concentrations), and (c) clearly defined biodiversity (number of native species, species lists or IBI-scores).3. The number of native taxa found in each study was transferred in an index of relative taxon richness (RTR) ranging from 0 (severely altered) to 100 (pristine reference conditions). Only those taxa were included that were (at least) present in the most pristine situation. This made it possible to combine, compare and analyse results from different studies. Catchment Land use was expressed as the percentage of non-natural Land use (agriculture, industry, housing or mining). As a measure of nutrients, the concentrations of NO 3 , NH 4 , PO 4 , total N and total P in the river and stream water were used.4. Over 240 published articles have been studied, but only 22 met the criteria described above and could be used for further analysis.5. This study showed that altered catchment Land use has a major effect on freshwater biodiversity and that the rate of species loss is serious; on average every 10% of lost natural catchment Land use cover leads to a loss of almost 6% ( AE 0.83) of the native freshwater fish and macroinvertebrate species.

“…NMS is a nonparametric ordination technique that is one of the most robust methods for exploring biological community data (McCune, 1994;Cao et al, 1996). Dimensionality of the ordination solution was determined using the scree test (Kruskal and Wish, 1978) to assess the point at which additional axes provided little improvement in fit (stress reduction).…”
