Comparing modified biological monitoring working party score system and several biological indices based on macroinvertebrates for water-quality assessment

Macroinvertebrate communities from the lower Nysa Kłodzka River catchment, southern Poland, were analyzed seasonally, in order to assess changes in their composition and structure, in relation to water quality. Two major groups of sites, differing in both morphological structure and taxonomical composition by cluster analysis, were identified within the catchment area. Wider and deeper sites, located along the Nysa Kłodzka River, were associated with the dominance of Chironomidae. Sites assigned along tributaries were characterized by a diversified structure of dominant taxa, including Oligochaeta, Hirudinea, Crustacea, Trichoptera, Ephemeroptera and Diptera. The performance of the modified procedure, named BMWP(PL) index, in accurately classifying 26 sites has been assessed through comparison with saprobic, diversity and biotic indices as well as chemical data. Due to diversified taxa richness and the presence or absence of specific indicator groups, values of the BMWP(PL) index varied from 27 to 93, and were correlated with the other biological indices and chemical variables. It has been stated that there is strong potential for application of the BMWP(PL) system in Poland, although some further testing is recommended.     

巢湖流域不同水系大型底栖动物群落结构及影响因素

2013年4月对巢湖流域8个水系147个样点的大型底栖动物进行调查,分析其群落结构及与环境因子的关系.共采集到大型底栖动物213种,隶属于3门7纲22目76科177属.8个水系大型底栖动物物种数差异较大,在杭埠河发现172种,而在十五里河仅发现10种.大型底栖动物密度组成呈现出显著的空间差异.南淝河和十五里河的寡毛纲相对密度均超过96%,派河的寡毛纲和摇蚊幼虫的相对密度分别为47.8%和41.1%.裕溪河、白石天河、柘皋河和杭埠河的腹足纲相对密度最大.杭埠河的水生昆虫相对密度达30.6%,是水生昆虫相对密度最大的水系.相似性分析结果表明,8个水系特征种差异明显,霍甫水丝蚓(Limnodrilus hoffmeisteri)是十五里河和派河的最主要优势种,而铜锈环棱螺(Bellamya aeruginosa)是兆河、裕溪河、杭埠河、白石天河和柘皋河的最主要优势种,铜锈环棱螺和霍甫水丝蚓是南淝河贡献率较大的两种优势种.生物多样性结果表明,Shannon-Wiener、Simpson及Margalef指数在8个水系间具有显著差异,Pielou指数在8个水系间差异不明显.典范对应分析结果表明,影响大型底栖动物群落结构的主要因素为水体营养状态和底质异质性.高营养盐浓度导致南淝河、派河和十五里河的耐污种密度高、生物多样性低,而相对较高的底质异质性维持了杭埠河大型底栖动物的高多样性和敏感型物种的生存.     

Impact of urbanization on the ecology of Mukuvisi River,Harare, Zimbabwe

The main objective in this study was to compare the physico-chemical characteristics and biota of a river (Mukuvisi) passing through an urban area to that of a non-urbanised river (Gwebi). Five sites in the Mukuvisi River and five sites in the Gwebi River were sampled for water physico-chemical parameters (pH, conductivity, DO, BOD, TDS, ammonia, Cl, SO₄²⁻, PO₄²⁻, NO₃³⁻, F⁻, Pb, Cu, Fe, Mn, Zn and Cr) once every month between August, 2012–August, 2013. Cluster analysis based on the physico-chemical parameters grouped the sites into two groups. Mukuvisi River sites formed their own grouping except for one site which was grouped with Gwebi River sites. Principal Component Analysis (PCA) was used to extract the physico-chemical parameters that account for most variations in water quality in the Mukuvisi and Gwebi Rivers. PCA identified sulphate, chloride, fluoride, iron, manganese and zinc as the major factors contributing to the variability of Mukuvisi River water quality. In the Gwebi river, sulphate, nitrate, fluoride and copper accounted for most of the variation in water quality. Canonical Correspondence Analysis (CCA) was used to explore the relationship between physico-chemical parameters and macroinvertebrate communities. CCA plots in both Mukuvisi and Gwebi Rivers showed significant relationships between macroinvertebrate communities and water quality variables. Phosphate, ammonia and nitrates were correlated with Chironomidae and Simulidae. Gwebi River had higher (P < 0.05, ANOVA) macroinvertebrates and fish diversity than Mukuvisi River. Clarias gariepinus from the Mukuvisi River had high liver histological lesions and low AChE activity and this led to lower growth rates in this river.     

基于多维度指数的雅鲁藏布江鱼类多样性评价及群落构建过程分析

雅鲁藏布江是我国西藏地区最大的河流,孕育着独特的水生生物资源。近年来随着人类活动的干扰与河流开发的推进,亟待对该流域水生生物多样性进行全面调查评估。本研究基于雅鲁藏布江全流域的鱼类资源调查数据,整合物种多样性、功能多样性和系统发育多样性3个维度12项指数,对该流域鱼类多样性进行评价分析。结果显示,24个调查样点中共采集到37种鱼类,隶属于3目7科24属;其中土著鱼类27种,外来鱼类10种;鲤形目鲤科鱼类为优势类群。基于Bray-Curtis相异度的层次聚类可将雅鲁藏布江鱼类群落划分为4组,表现为帕隆藏布汇口以上/以下江段及两个江段内干支流间存在较大差异,这与区域生物地理学过程及河流环境梯度密切相关。利用12项多样性指数对各组群的鱼类多样性进行评估,结果表明,除Simpson多样性指数、Pielou均匀度指数、平均配对种间系统发育距离指数和平均最近种间系统发育距离(MNTD)指数外,其他指数检测到组间的显著性差异。不同多样性指数之间的相关关系表现各异:与丰富度相关的多项指数间存在显著或极显著的正相关,功能离散度指数和MNTD指数与其他指数间多存在显著或极显著的负相关,表明不同类别的多样性指数各自具有独特的指示价值。基于群落功能性状结构和系统发育结构的检验结果显示,大多数样点驱动鱼类群落聚合的过程为种间竞争排斥,推测与雅鲁藏布江水体营养贫瘠、食物来源稀缺导致的种间营养竞争关系紧张有关。本文整合多维度多样性指数对雅鲁藏布江流域鱼类多样性及群落构建过程进行探究,以期为该流域鱼类资源保护和管理提供科学依据,也为应用多维度指数评价淡水鱼类多样性提供参考借鉴。     

河流大型底栖动物对环境压力的响应:以太湖、巢湖流域为例

为了解河流大型底栖动物对环境压力的响应关系,以人类干扰程度不同的太湖流域和巢湖流域为研究区,系统调查区域内河流大型底栖动物,结合水体、沉积物理化数据及生境质量状况,运用空间分析和多元统计分析等方法,探讨了大型底栖动物多样性及典型物种对关键环境因素的响应规律.结果表明,太湖流域和巢湖流域的环境质量和大型底栖动物群落结构均差异较大,巢湖流域的生境质量优于太湖流域,巢湖流域平原区部分点位的水体营养盐(特别是氮浓度)高于太湖流域平原区.巢湖流域丘陵区的敏感型物种(主要为水生昆虫)密度远高于太湖流域丘陵区,太湖流域丘陵区的耐污型物种(寡毛纲)平均密度稍高于巢湖流域丘陵区,而巢湖流域平原区的寡毛纲霍甫水丝蚓(Limnodrilus hoffmeisteri)和苏氏尾鳃蚓(Branchiura sowerbyi)平均密度远高于太湖流域平原区.广义加性模型建立的响应关系曲线表明,栖境多样性和总氮浓度可以作为生物多样性的指示因子.铜锈环棱螺(Bellamya aeruginosa)、椭圆萝卜螺(Radix swinhoei)、河蚬(Corbicula fluminea)、霍甫水丝蚓、苏氏尾鳃蚓、黄色羽摇蚊(Chironomus flaviplumus)等特征物种与特定环境因子的响应关系显著,这些物种也可以作为环境监测的指示物种.底栖动物环境梯度的响应曲线能够定量地描述底栖动物群落对环境因子的响应关系,有利于深入了解水体水质、营养状态及生境质量与大型底栖动物群落结构的相关关系,进而预测不同人为干扰下大型底栖动物群落结构的变化趋势和演替过程.

Seasonal variation in benthic macroinvertebrate assemblages and water quality in an Afrotropical river catchment,northeastern Tanzania

Population growth and economic development have resulted in increased water demands, threatening freshwater resources. In riverine ecosystems, continuous monitoring of the river quality is needed to follow up on their ecological condition in the light of water pollution and habitat degradation. However, in many parts of the world, such monitoring is lacking, and ecological indicators have not been defined. In this study, we assessed seasonal variation in benthic macroinvertebrate assemblages in a tropical river catchment in northeastern Tanzania, which currently experiencing an increase in agricultural activities. We examined the potential of in-stream environmental variables and land-use patterns to predict the river macroinvertebrate assemblages, and also identified indicator taxa linked to specific water quality conditions. Macroinvertebrate abundance, taxon richness and TARISS (Tanzania River Scoring System) score were higher in the dry season most likely due to higher surface runoff from agricultural land and poorer water quality in the wet season. In the wet season macro invertebrates seem to be limited by chlorophyll-a, oxygen and phosphorous while in the dry season, when water flow is lower, nitrogen and turbidity become important. Substrate composition was important in both seasons. Given the fact that different selective filters limit macroinvertebrate assemblages in both seasons, a complete picture of water quality can only be established by monitoring in both seasons. Riparian buffer zones may help to alleviate some of the observed negative effects of agricultural activities on the river system in the wet season while limiting irrigation return flows may increase water quality in the dry season.     

Transitional and freshwater bioassessments: One site,two perspectives?

The freshwater–saltwater-transition-zone was analysed using two different sampling protocols and assessment methodologies, developed for freshwater and estuaries, to compare their agreement level in terms of community composition and quality assessments. The use of different protocols resulted in significant differences in macroinvertebrate communities, in index scores and initially in quality classes. After modifications in the sensitivity scores of the IBMWP and AMBI indices (average scores or the use of a score of the other index when both were present), the differences were largely reduced and quality classes became coincident for the assessments provided by IPtIs and BAT tools. Such harmonisation of quality assessments for adjacent water categories (e.g., large rivers vs. transitional waters), exemplified here as an harmonisation in one of the metrics comprised in the assessment tools, is essential as it has direct implications on the expansion and accomplishment of River Basin Management Plans committed by the Water Framework Directive.     

Comparative analysis of biotic indices in the monitoring system of running water in a biospheric reserve

Comparative analysis of six indices (TBI, FBI, BMWP, ASPPT, BBI, and EPT) was performed at nine sites in the Berezina River basin in the area of the Berezina Biospheric Reserve. The criterion for comparison was the coefficient of variations of an index for different sites in the same time moment and for the same site in different periods. The indices TBI, BMWP, and EPT were found to demonstrate the highest sensitivity and most adequate response to variations in water quality, which allows them to be recommended to be taken as standard.Translated from Vodnye Resursy, Vol. 32, No. 2, 2005, pp. 223–226.Original Russian Text Copyright © 2005 by Semenchenko, Moroz.     

澜沧江下游补远江大型底栖动物群落结构的时空分布及其影响因素

自然流淌的支流在维持建坝河流水生生物多样性中起着重要作用。补远江是澜沧江下游的重要一级支流,保持了较为天然的河流状态,人类活动干扰相对较少,是流域土著鱼类保护区和水生生物重要栖息地。在澜沧江流域水电开发的背景下,掌握补远江大型底栖动物群落结构的时空分布及其影响因素,对澜沧江乃至西南河流的水生生物多样性保护和恢复具有重要参考意义。于2019年4月(旱季)和2019年10月(雨季)对补远江的大型底栖动物进行了详细调查,共检出大型底栖动物150个分类单元,隶属于5门7纲68科,其中水生昆虫121种,软体动物20种,蛭类3种,寡毛类2种,甲壳类2种,涡虫、线虫各1种。毛翅目和蜉蝣目为全流域优势类群。补远江底栖动物密度和生物量在旱季和雨季均表现为上游大于中下游,物种丰富度和Shannon-Wiener多样性指数在雨季显著高于旱季。功能摄食类群中,滤食者(41.09%)和收集者(31.81%)占绝对优势,其次为刮食者(11.00%)、捕食者(11.21%),撕食者(4.89%)较少。Mantel检验分析表明,河宽(RW)、硝态氮(NO₃^--N)、化学需氧量(COD_Mn)是影响补远江大型底栖动物群落结构的主要环境因子;不同功能摄食类群所受到的环境影响因素不同。生物指数(BI)和生物监测工作组记分(BMWP)系统评价显示,补远江大部分样点处于良好及以上水平,少数样点处于中等及以下水平,总体水生态状况良好。     

Effect of streambed sediment on benthic ecology

Benthic macroinvertebrates have been commonly used as indicator species for assessment of aquatic ecology. Streambed sediment, or substrate, plays an important role in habitat conditions for macroinvertebrate communities. Field investigations were done to study the benthic diversity and macroinvertebrate compositions in various stream substrata. Sampling sites with different bed sediment, latitude, and climate were selected along the Yangtze River, the Yellow River, the East River, and the Juma River, in China. The results show that benthic community structures found in different substrata clearly differ, while those found in substrata of similar composition and flow conditions but in different macroclimates are similar. The study, thus, demonstrates that the benthic macroinvertebrate community is mainly affected by substrate composition and flow conditions, but is generally unaffected by latitudinal position and macroclimate. Taxa richness of the maeroinvertebrate community was found to be the highest on hydrophyte-covered cobbles, high on moss-covered bedrock, and low on clay beds and cobble beds devoid of plant biomass. Sandy beds are compact and unstable, thus, no benthic macroinvertebrates were found colonizing such substrata. Aquatic insects account for most of the macroinvertebrates collected in these rivers. Different insects dominate in different types of substrata： mainly EPT species （Ephemeroptera, Ptecoptera, Tfichoptera） in cobble, gravel, and moss-covered bedrock; and Chironomidae larvae in clay beds. The relation between the number of species in the samples and the size of the sampling area fits a power function of the species area. One square meter （lm） is suggested as the minimum sampling area. A substrate suitability index is proposed by integrating the suitability of sediment, periphyton, and benthic organic materials for macroinvertebrates. The biodiversity of macroinvertebrates increases linearly with the substrate suitability index. Benthic taxa richness increases linearly with the suitability index.     

Water quality variations in different climates of Iran: toward modeling total dissolved solid using soft computing techniques

In present paper, wavelet analysis of total dissolved solid that monitored at Nazlu Chay (northwest of Iran), Tajan (north of Iran), Zayandeh Rud (central of Iran) and Helleh (south of Iran) basins with various climatic conditions, have been studied. Daubechies wavelet at suitable level (db4) has been calculated for TDS of each selected basins. The performance of artificial neural networks (ANN), two different adaptive-neurofuzzy inference system (ANFIS) including ANFIS with grid partition (ANFIS-GP) and ANFIS with subtractive clustering (ANFIS-SC), gene expression programming (GEP), wavelet-ANN, wavelet-ANFIS and wavelet-GEP in predicting TDS of mentioned basins were assessed over a period of 20 years at twelve different hydrometric stations. EC (μmhos/cm), Na (meq L^?1) and Cl (meq L^?1) parameters were selected (based on Pearson correlation) as input variables to forecast amount of TDS in four studied basins. To develop hybrid wavelet-AI models, the original observed data series was decomposed into sub-time series using Daubechies wavelets at suitable level for each basin. Based on the statistical criteria of correlation coefficient (R), root mean square error (RMSE) and mean absolute error (MAE), the hybrid wavelet-AI models performance were better than single AI models in all basins. A comparison was made between these artificial intelligence approaches which emphasized the superiority of wavelet-GEP over the other intelligent models with amount of RMSE 18.978, 6.774, 9.639 and 318.363 mg/l, in Nazlu Chay, Tajan, Zayandeh Rud and Helleh basins, respectively.     

Concept of planktonic species diversity in small water bodies – a case study of lake Rangasagar (Udaipur: Rajasthan)

The quantitative and qualitative relationships within phyto- and zooplanktonic communities were examined for a period of one year in a small eutrophic lake in Udaipur, through the application of diversity indices. The results revealed that a higher plankton diversity needs not necessarily lead to a greater community diversity or evenness of species diversity. The phytoplankton species diversity was related to nutrients and ambient environmental factors. Within zooplankton groups, the diversity index was found influenced by the evenness and richness of the species. On the other hand, the strong correlation between individual species density and community diversity in the cladocera was influenced by food availability. The total zooplankton diversity was also strongly correlated (P < 0.01) with the number of species and equality. There was no spatial variation in species composition because of smaller spread of the water body. It is felt that the diversity indices could get influenced by the dominance or scarcity of one or more species or communities giving a deceptive picture of planktonic panorama.     

Macroinvertebrate community structure and feeding interactions along a pollution gradient in Gilgel Gibe watershed,Ethiopia: Implications for biomonitoring

Feeding interactions among functional feeding groups (FFGs) of macroinvertebrates are robust indicators of aquatic ecosystem interactions. They provide information regarding organic matter processing, habitat condition and trophic dynamics. In tropical rivers with pronounced wet and dry seasons, macroinvertebrate based ecological monitoring tools are explicitly focused on metrics and indices, while ignoring interactions of FFGs. Therefore, the objective of this study was to investigate the functional feeding type metrics, diversity indices and feeding interactions among FFGs of macroinvertebrates along the water pollution gradient in Gilgel Gibe watershed, Ethiopia. Water quality parameters and macroinvertebrate community attributes were assessed for samples collected from upstream sites (15 sites), urban-impacted stretches (12 sites) and wetland-affected river zones (7 sites) of the watershed during the rainy (July) and dry (February) seasons. To understand the effect of pollution on the feeding interactions, stable carbon and nitrogen isotopes were analyzed. Macroinvertebrate-based diversity indices and functional feeding type metric showed deterioration of ecological integrity at the urban-impacted sites and substantial recovery in the wetland-affected downstream sites. Omnivorous feeding behavior of macroinvertebrates was noted for the upstream sites, whereas clear trophic guilds of FFGs were suggested for the wetland-affected river zones by the stable isotope results. The results of pollution gradient analysis and feeding interactions among FFGs revealed that the urban-impacted sites showed weaker interactions when compared to upstream and wetland influenced sites. This affirms the potential importance of feeding interactions among FFGs of macroinvertebrates in water quality monitoring.     

Identifying key environmental variables structuring benthic fauna for establishing a biotic typology for Greek running waters

A central aspect of the Water Framework Directive 2000/60/EC addressed to Member Countries is to proceed to type-specific ecological assessment and classification by establishing typology systems. Sixty-four permanent stream sites distributed throughout mainland Greece and islands were assessed with macroinvertebrate indicators to evaluate their ecological quality. Local and catchment scale parameters were determined and recorded to obtain an integrated assessment of the main factors affecting stream integrity and macroinvertebrate communities. Twenty-three sites were classified as reference or good status in terms of biological, chemical and hydromorphological quality with the use of various metrics. Multivariate statistical techniques were performed (MDS, BIOENV, correlation analysis and PCA) to investigate the main environmental factors structuring benthic macroinvertebrate communities and to select candidate environmental variables for establishing a biotic typology for Hellenic rivers. The results revealed relatively distinct macroinvertebrate communities within defined abiotic zones of the country. Assemblages of macroinvertebrate fauna were most strongly associated to differences in geographical position, altitude, slope, catchment area, current velocity, conductivity and water temperature. In view of the lack of sufficient data at the country level on the three last variables and after considering cause-effect relationships between large scale variables and the latter, it has been demonstrated that a number of catchment scale variables could be used as robust surrogates.     

Ecological condition,biodiversity and major environmental challenges in a tropical river network in the Bago District in South-central Myanmar: First insights to the unknown

Freshwater ecosystems in the Indo-Burma biodiversity hotspot face immediate threats through habitat loss and species extinction. Systems to monitor ecological status and trends in biodiversity are therefore crucially needed. Myanmar is part of Indo-Burma but with no past experience of biomonitoring in freshwaters. In this study, we aimed to assess the ecological and biodiversity status of a lowland river network in south-central Myanmar by identifying and quantifying pressures using macroinvertebrates as bioindicators. Novel data on water quality (nutrients, sediments and metals), hydromorphology (Morphological Quality Index; MQI), habitat quality (Litter-Siltation Index; LSI), land use, and macroinvertebrates were collected from 25 river sites. The dominant pressures on rivers were urban land use, inputs of untreated sewage, in-stream and riparian garbage littering, run-off from agricultural fields and plantations, as well as physical habitat degradation. Water chemistry data indicated inputs of sediments and nutrients to degraded streams, but no obvious metal pollution. The LSI and MQI indices indicated high perturbation in agricultural and urban areas, respectively. Ecological status was assessed using a first version of a modified Average Score per Taxon index (ASPT), while biodiversity was assessed by family richness within the orders Ephemeroptera, Plecoptera, Trichoptera, Coleoptera and Odonata (EPTCO), which was tested against the pressure gradient by principal component regressions. ASPT had high diagnostic capabilities (R² = 0.68, p < 0.001) and showed that the index can be used to evaluate ecological water quality in this region. Biodiversity, expressed as family richness, also declined along the gradient (R² = 0.59, p = 0.041), giving support to the fact that current land-use practices in this area are unsustainable.     

江西省浅水湖泊大型底栖无脊椎动物多样性特征和影响因素

2019年春、秋两季,对江西省76个湖泊的底栖动物进行了调查,在分析其群落结构和多样性的基础上,探讨了多样性与环境因子间的关系,旨在确定影响大型底栖无脊椎动物多样性的重要环境因子,以期为江西省湖泊的精准化管理提供科学依据和技术支持。两次调查共检出140个分类单元,以水生昆虫和软体动物为主,摇蚊类物种数占水生昆虫物种数的53.62%。富营养指示种(长足摇蚊属一种和摇蚊属一种)为春、秋两季的优势分类单元,湖沼典型种(长足摇蚊属一种、摇蚊属一种、石田螺属一种、苏氏尾鳃蚓和霍甫水丝蚓)的丰度变化导致了群落结构的季节变化。大型底栖无脊椎动物α多样性水平较低,基于PLSR和PLS-SEM的分析结果表明,影响大型底栖无脊椎动物多样性指标的环境因子既与藻类种群动态密切相关,也与水质状态有关。大型底栖无脊椎动物多样性与藻类种群状态存在稳定的联系,不受季节因素的影响,过高的藻类丰度不利于大型底栖无脊椎动物多样性的提高,而较好的水质状况有利于大型底栖无脊椎动物多样性的提高。为保护江西省湖泊大型底栖无脊椎动物资源,应在具有渔业养殖功能的湖泊和城镇湖泊中进行水生植物的修复工作,使藻型湖泊向草型湖泊方向演化;对一...     

Land-use influence on the functional organization of Afrotropical macroinvertebrate assemblages

Studies investigating the effects of human activities on the functional organization of macroinvertebrate communities in tropical streams and rivers are very limited, despite these areas witnessing the greatest loss of natural forests globally. We investigated changes in taxon richness, numerical abundance and biomass of macroinvertebrate functional feeding groups (FFGs) in streams draining different land-use types in the Sosiani-Kipkaren River in western Kenya. Twenty-one sites in river reaches categorized as forested, mixed, urban or agricultural were sampled during the dry and wet seasons. Collected macroinvertebrates were identified to the lowest taxon possible (mainly genus) and classified into five major FFGs; collector-gatherers, collector-filterers, scrapers, predators and shredders. There were significant (p < 0.05) spatial variation in habitat quality, organic matter standing stocks, total suspended solids, electrical conductivity, dissolved oxygen, temperature and nutrient concentrations across land-uses, with forested sites recording lowest values in mean water temperature, electrical conductivity and nutrients while recording highest levels in dissolved oxygen concentrations. Responses in macroinvertebrates to changes in land-use varied with richness, abundance and biomass showing differences within FFGs. Biomass-based metrics responded more strongly to change in land-use while taxon richness was the least predictive, indicating replacement of taxa within FFGs across land-use types. Higher shredder abundance, biomass and richness were recorded in forested streams which were cooler with protected riparian areas and high biomass of coarse particulate organic matter. Collector-gatherers dominated agricultural and urban streams owing to an abundance of particulate organic matter and nutrients, while scrapers responded positively to increased nutrient levels and open canopy in mixed and agricultural streams where primary production and algal biomass was likely increased. Overall, this study provides further evidence of the effects of agricultural and urban land-uses on tropical streams and rivers and contributes to the use of macroinvertebrate FFGs as indicators of ecological health.
