“…They are an important part of the food chain, especially for fish and other predators (Strayer, 2006), and many feed on plankton and bacteria on the lower end of the food chain. They can regulate rates of primary production, decomposition, water clarity, thermal stratification and nutrient cycling in lakes (Strayer, 2006) and are widely used for biomonitoring (Gezie, Anteneh, Dejen, & Tiku, 2017;Jun, Won, Lee, Kong, & Hwang, 2012;Poikane et al, 2016;Sandin & Hering, 2004;Wang, Zheng, Liu, & Wang, 2015) because of their specific life-history traits and ecology (Voshell, 2002).…”

In developing tropical countries, the littoral region of lakes is exposed to high human pressures, and the degradation effects are more evident on riparian vegetation and macrophytes. Human impacts on other biological entities, such as plankton and macroinvertebrates, are rarely investigated and reported. The present study focuses on assessing the effects of habitat disturbance on the littoral macroinvertebrate assemblages in Lake Hawassa, Ethiopia. Samples were taken from February to November 2015/16 from 12 sampling sites purposefully selected on the basis of percentage disturbance score (PDS) and categorized into minimally disturbed (four sites), moderately disturbed (five sites) and highly disturbed (three sites). Macroinvertebrate samples were collected from each site using a D‐frame net of 500 µm, with both in situ measurement and laboratory analysis of the environmental variables being conducted. A total of 23,051 macroinvertebrates belonging to 43 families were identified. Analysis of similarities (ANOSIM) and non‐metric multidimensional scaling (NMDS) analyses revealed significantly different macroinvertebrate assemblages among the disturbance levels (ANOSIM: p = .004, R = .55). Variables such as Biological Monitoring Working Party, Shannon diversity index, Ephemeroptera and Trichoptera (ET) family richness, and family richness exhibited a flawless pattern of decrease with increasing human disturbances and a negative correlation with nutrients. The reduction of these metrics for highly disturbed sites was attributable to the deterioration of vegetation and bottom substrate qualities, increasing stormwater inputs, lack of buffer zones and well‐planned land use induced by human interventions. It was evident anthropogenic activities in and around the littoral zone of the lake contributed to the degradation of habitat quality and decreased macroinvertebrate richness and abundance. Thus, effective lake management practices are recommended to rehabilitate the degraded littoral habitat quality in order to realize the sustainable use of this natural resource.

“…When both historical data and authoritative standards are lacking for specific indices, e.g., phytoplankton, zooplankton, and benthic macroinvertebrates, the LDC was used. Adhering to the literature [7,14], the reference site approach was adopted. The 5th/95th best percentile of the candidate sites increasing/decreasing with disturbance was used to select the reference sites (e.g., <5% blue-green algae biomass or >95% large Daphnia density).…”

Abstract:The development of an ecosystem health index to assess health status in freshwater lakes is urgently needed in China, especially in polluted lakes. This study developed a specific Ecosystem Health Index (LP-EHI) for Lake Poyang in China. LP-EHI quantified lake health from the perspectives of physical, chemical, biological integrity and social service. Physical integrity indices included hydrological conditions (water level and runoff), basic morphometric characteristics (lake area and shoreline), and tributary connectivity. Chemical integrity indices used water quality, nutrition, and toxicity to quantify chemical impairment. Biological integrity indicators covered six major components of the aquatic food chain, namely, phytoplankton, zooplankton, benthic macroinvertebrates, wetland plants, fish, and wintering birds. Social service indices included drinking water, pathogenic potential, flood storage capacity, sand mining, and dish-shaped sub-lake areas under management to measure whether the lake fulfilled the needs of human society. Reference and impaired conditions for each metric were defined by "historical" conditions, "least disturbed" conditions, national standards and expert opinions. The value of LP-EHI ranging from 0 to 1 was divided into five health conditions: excellent (≥0.8), good (0.6-0.8), fair (0.4-0.6), poor (0.2-0.4) and bad (<0.2). The metrics' reliability was further validated using a box-and-whisker plot test. The developed index (LP-EHI) is so far the most comprehensive index to evaluate ecosystem health for Lake Poyang, and is well reflected in the unique characteristics of Lake Poyang. It can enhance our understanding of lake health conditions and thus guide lake management to achieve better health conditions.

“…Biological integrity can be used to measure the changes in the composition of biologic communities to reflect the ecological complexity (Broecka et al, 2015;Lavoiea et al, 2014;Lee and An, 2014;Ondiviela et al, 2015;Wang et al, 2015). Ecosystem health assessment can be divided into two categories: Qualitative evaluation, quantitative evaluation.…”
