“…The study indicated the quite correlation-ship with overall species richness across the sites and may be required to best managed by the biodiversity conservation managers for conservation and habitat restoration. Sharma et al, (2004) also found such kind of relation in aquatic organisms at Dhauli Ganga. Rout and Gaur (1994) reported the Shannon diversity index as greater (1.6 -4.1) in Shillong stream at Assam and higher indexing (2.6 -4.1) was reported at Alps stream from upper parts of Himalaya by Cantonati et al (2001).…”

Abstract:The present contribution encompasses on plankton and biological productivity as ecological indicator for identifying the ecological quality of Sahastradhara stream (between 27 km stream stretches), located in the Doon Valley of Garhwal region in India. Monthly sampling from all the sampling sites was made for a period of 12 months (May 2009 -April 2010 at 9:00-11: 00 AM. A total of 40 taxa from different classes of plankton and zooplankton were reported. The phytoplankton (32 sp.) was found being the most abundant taxa than zooplankton (9 sp.) in Sahastradhara stream. Fluctuation in the phytoplankton density was recorded highest (1536 unit/l) during winter and lowest (20 unit/l) during monsoon. Zooplanktons were reported to be maximum (147 unit/l) during summer and minimum (3 unit/l) during monsoon. The total diatoms were reported highest (1022unit/l) during starting the winter and lowest (4 unit/l) during monsoon. Green algae and blue green algae were reported to be maximum during winter and minimum during summer. The Shannon-wiener diversity index calculated for the density of Bacillariophyceae (0.2180-0.366), Chlorophyceae (0.208-0.367) and Cyanophyceae (0.391-0.366) and correlation was made between Plankton biomass and physico-chemical parameters to analyses the relative features of the both variables. The density of plankton and biological productivity were influenced by disturbances in the photic zone and indiscriminate anthropogenic activities for tourist development resulted aquatic habitat degradation in stream ecosystem.

“…Such communities respond to changing habitats and water quality by variations in community structure (Sharma et al 2004). Several factors were known to influence the distribution of aquatic insects, but the important factors likely to affect the diversity and abundance in an aquatic ecosystem are water temperature, water velocity, substrate composition, hydromedian depth and turbidity.…”

“…Some of the studies have also been made in different parts of the Indian subcontinent (Das 1971;Bisht and Das 1979a, b;Paul et al 1998;Joshi et al 2002). However, no in-depth study on the diversity of aquatic insects of headwater streams has been done so far, except some scattered reports made by Badola 1979;Sharma 1984;1986;Sharma et al 2004. Therefore, the present maiden contribution on Chandrabhaga, a tributary of the River Alaknanda of Garhwal Himalayas, is very important.…”

“…Aquatic biodiversity is one of the most essential characteristics of the aquatic ecosystem for maintaining its stability and a means of coping with any environmental change (Vinson and Hawkins 1998;Sharma et al 2004). Biodiversity baseline data for near natural reference rivers and river segments are badly needed to develop viable conservation and management strategies (Ward and Tockner 2001).…”

However, no effort has been made so far to study the macro-invertebrates dwelling in the rivers of Doon Valley, India, inspite of the fact that the wide variety of microhabitats (rock surfaces, plant surfaces, leaf debris, logs, back waters, sandy sediments, crevices in gravel and pebbles) are available in the rivers of Doon Valley to aquatic macro-invertebrates.…”

A survey of macro-invertebrates and their monthly variations occupying the Tons river in Doon Valley was conducted from August 2003-July 2004.Macro-invertebrate collections and water samples were taken from three sampling stations every month during the period of study. All the hydrological attributes were measured monthly for 1 year. The present study showed that the water velocity, hydromedian depth, turbidity and dissolved oxygen and nature and size of the bottom substrates do play a major role in determining the macro-invertebrate diversity of Tons river. The ecological relevance of the measured hydrological attributes was investigated by comparing their degree of correlation with invertebrate density and diversity. The Shannon-Wiener index (H 0 ) of macro-invertebrates was found to be highest (3.60) during spring season (February and March) and lowest (2.59) during monsoon season (July and August). The high values of diversity index of macro-invertebrates at all the three sampling sites indicate diverse macro-invertebrate communities in the Tons river in Doon Valley, India.
