Taschenbuch. Zustand: Neu. Neuware -Determine similarities and differences in taxonomic composition and features of the characteristic assemblages of the benthic macroinvertebrate community in the streams of Bundelkhand and Doon regions and also the factors governing the abundance and assemblages within and among these regions. In both regions, physico-chemical variables show differences. The richness and density vary spatially. Within Bundelkhand the Paisuni and Ken while in Doon, the Asan and Tawa are richer than the Tons and Suswa in respective regions. The Bundelkhand is richer than the Doon region. Densities are highest for the Ken in the former and both Suswa and Asan in the latter regions, respectively. Densities are high in Doon compared with the Bundelkhand region. The taxonomic composition also varied among the tow eco-region. Scrapers and collectors are major functional groups in both regions, but former dominate in Bundelkhand while latter in the Doon. CCA shows that only 5 of the 11 factors (environmental variables) influence the composition of the benthic macroinvertebrate in both regions.Books on Demand GmbH, Überseering 33, 22297 Hamburg 104 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Benthic macroinvertebrates are important component of aquatic ecosystem and are extensively used in bio-monitoring. The rivers of Central India are mainly impacted with agriculture; the river water is very under stress due to agriculture, domestic use. The three rivers of this region; Ken, Paisuni and Tons were studied longitudinally to test the ¿Biome Dependency Hypotheses¿. Insects were dominant in the Ken and Paisuni while Gastropods in the Tons. The taxonomic composition showed better relationship in Ken and Paisuni, while patchy distribution in Tons. Only few taxa show clear-cut trend of longitudinal increase or decrease. The characteristic taxa varied at each station within the river and also among the rivers. Substratum was most important factor for variation in taxonomic composition at various station in the Ken and Tons, while current velocity in the Paisuni. The environmental variables differed at larger scale (river), landuse in the Ken, current velocity in the Paisuni and substratum in the Tons. In the Ken two type of food chains were evident in upper and lower part i.e.grazing and detritus type. However, only detritus food chain was dominant in Paisuni and Tons.Books on Demand GmbH, Überseering 33, 22297 Hamburg 212 pp. Englisch.
