“…The rapid colonization of invertebrate communities is common in created, restored, and recently flooded wetlands (Streever et al, 1996;Brown et al, 1997;Fairchild et al, 1999;Ashley et al, 2000;Anderson & Smith, 2004). The proximity of mitigation wetlands to rivers, streams, and other wetlands is known to facilitate colonization of invertebrates (Nelson et al, 2000). Almost all of the mitigation wetlands in this study, as well as reference wetlands, were located near major water sources.…”

“…These conditions likely favored Gastropoda colonization and probably reflect their ubiquitous distribution throughout emergent and open water areas of mitigation wetlands. This phenomenon is not uncommon throughout wetland studies Nelson et al, 2000). This trend was evident because of such unproportionally high numbers of Planorbidae in emergent areas of Altona Marsh, a natural marl wetland with alkaline conditions.…”

Aquatic macroinvertebrate assemblages in mitigated and natural wetlands

Many wetlands have been constructed in West Virginia as mitigation for a variety of human disturbances, but no comprehensive evaluation on their success has been conducted. Macroinvertebrates are extremely valuable components of functioning wetland ecosystems. As such, benthic and water column invertebrate communities were chosen as surrogates for wetland function in the evaluation of 11 mitigation and 4 reference wetlands in West Virginia. Mitigation wetlands ranged in age from 4 to 21 years old. Overall familial richness, diversity, density and biomass were similar between mitigation and reference wetlands (p > 0.05). Within open water habitats, total benthic invertebrate density was higher in reference wetlands, but mass of common taxa from water column samples was higher in mitigation wetlands (p < 0.05). Planorbidae density from benthic samples in emergent habitats was higher in reference than mitigated wetlands. Benthic Oligochaeta density was higher across open water habitats in mitigation wetlands. All other benthic taxa were similar between wetland types. Among the most common water column orders, Isopoda density was higher in reference wetlands, but Physidae density was higher in mitigation wetlands. Within mitigation wetlands, emergent areas contained higher richness and diversity than open areas. These data indicate that mitigation and reference wetlands generally support similar invertebrate assemblages, especially among benthic populations. The few observed differences are likely attributable to differences in vegetative community composition and structure. Mitigation wetlands currently support abundant and productive invertebrate communities, and as such, provide quality habitat for wetland dependent wildlife species, especially waterbirds and anurans.

“…The wind speed data for the same period (Fig. 3d) The ecological effects of low dissolved oxygen concentrations and pH are far reaching: Nelson et al (2000) found that in a study of constructed wetlands in New Mexico, invertebrate taxa richness was positively related to dissolved oxygen concentration. The importance of invertebrates in wetland functioning and as a food source has promoted suggestions that invertebrates should be used, along with other criteria, to compare the state of wetlands (Streever et al, 1996).…”

The widespread loss and degradation of UK wetlands over the last 200 years has resulted in a loss of habitat for wading and migrating birds To help stem this decline, wetland areas are now being preserved and where possible created. This study investigated water quality in a recreated reed bed in south-west England designed specifically to provide habitat for birds. Since June 2000, continuous measurements of temperature, pH, electrical conductivity and dissolved oxygen have been logged. These data enable the partial pressure of CO 2 to be calculated. This paper looks at the data collected up to November 2001. Despite similar solar radiation and water temperature conditions in both 2000 and 2001, peak summertime values of dissolved oxygen dropped from >100% to <50% and pH values dropped from >7.7 to <7.2. Both also show a reduction in diurnal variation. Over the same period, the average partial pressure of CO 2 increased from 19.7 to 56.1. Analysis of the diurnal dissolved oxygen curves indicates a decrease in photosynthesis which, in the absence of a change in nutrient concentrations in the water, may result from surface plant growth or from a reduction in submerged plant cover. The implications of these changing hydro-chemical conditions are that the site will be less able to support such a wide diversity of aquatic fauna, which will reduce the effectiveness of the site as a habitat for some bird species.

“…Nelson et al (2000) have also shown that dissolved oxygen has a strong influence on macro-invertebrate community structure. They opined that the higher dissolved oxygen level in open water habitats is necessary for substantive growth of macro-invertebrate populations.…”

Surveying macro-invertebrate diversity in the Tons river, Doon Valley, India

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.
