BOOK REVIEW: Bauernfeind E. & Soldán T. 2012: The Mayflies of Europe (Ephemeroptera).

Rashid branch of Nile River is a principle stream in Kafr El Zayat (Gharbyia governorate) for drinking and irrigation to different essential crops. Five stations were selected for seasonal collection, resulted in 539 specimens, belonging to 7 orders and 22 families and 31 species. The total population density was higher during Spring (41.9%), then in Summer (25.1). Order Diptera was the most abundant (33.8%), represented by 5 families (Chironomidae, Culicidae, Ephydridae, Tabanidae & Stratiomyiidae) with the highest value during Spring season; then order Hemiptera (19.5%), represented by 5 families (Blestomatidae, Croxidae, Mesovillidae, Villidae & Notonectidae) with the highest value also during Spring season; followed by order Coleoptera (16.9%) with 6 families (Hydrophylidae, Dytiscidae, Noteridae, Hydranaeidae, Curculionidae & Staphylinidae), the highest representation was during Summer season; then order Odonata (16.7%), 2 families (Libellulidae & Coenagrionidae) , the highest representation was during Spring; order Ephemeroptera (9.5%), 2 families ( Baetidae & Caenidae), the highest value was during Spring; lastly order Trichoptera and Orthoptera each with one family during Summer and Winter respectively. Family Tridactylidae and Staphylinidae are collected for the first time from streams in Egypt. Tables, Figures, Keys, diagnosis and notes on habitat, in addition to detailed colored photographs with diagnostic features to all collected species were introduced to facilitate the correct identification that permits the utilization of these aquatic insects as bioindicators in monitoring programs for reflecting the ecological contents and pollution level of aquatic ecosystem along this stream.

Waste to phosphorus: A transdisciplinary solution to P recovery from wastewater based on the TRIZ approach.

For decades, the river health of the Yellow River source region (YRSR) on the Qinghai-Tibetan Plateau has been a focal issue owing to its unique geographic location and ecological functions. This study investigated the ecological status of the headwater streams, the main stem, and the tributaries of the Yellow River in the YRSR using the tolerance values of macroinvertebrates and those related to biotic indices. The macroinvertebrate assemblages of the headwater streams were characterized by lower biodiversity than the tributaries downstream, based on comparisons of taxonomical composition, functional feeding group composition, and the pollution-tolerant capacity of taxa. The headwater streams had a lower ratio (16%) of pollution-sensitive macroinvertebrate taxa than that of the tributaries downstream (30%). The biotic indices (family- and genus-level biotic indices) indicated that the ecological health of the headwater streams was comparably poorer than that of the downstream tributaries. The combined effect of vulnerable natural conditions and increasing human disturbance is likely the main cause of eco-environmental degradation in the Yellow River headwater streams.

Quantitative knowledge on the use of aquatic insects as bioindicators has not been elucidated in Egypt. Given these concerns, the goal of the present study is to use aquatic insect communities as biotic indices for evaluating water quality in some Egyptian fresh water streams. The study was carried out for a period of one year during summer and autumn 2010 and winter and spring 2011. Sampling was done using kicking and dipping method to collect the aquatic insects. Insects were identified up to the family level. Several metrics were used to analyze the aquatic insect data. Physic-chemical parameters of water samples were analyzed using standard methods. A total of 438 aquatic insect individuals (representing 19 families from 7 orders), 535 (20 insect families from 7 orders) and 241 (13 families from 6 orders) were recorded from El-Kassed, Rasheed and Kafr el Zayat streams. According to total taxa richness for Ephemeroptera, Plecoptera and Trichoptera (SEPT) -biotic index, the situation of water quality in the three water bodies was moderate impact; however it was "Good" according to Stroud water research center (SWRC). The SEPT is the most suitable biotic index for calculating water bio-class in Egyptian streams. Margalef's water quality index values were less than 3, indicating that the water quality of the three streams was impacted. Various anthropogenic activities were showing their impacts on the water quality of Egyptian streams. This study, as elsewhere, shows that aquatic insect communities could be good indicators of water quality and should be used as bioindicators of water quality of fresh water streams in Egypt.

Aquatic Insects as Bio Indicators for Pollution in Some Egyptian Streams.

Environmental monitoring of river water quality in Albania, using biological and chemical parameters, is a fast and effective way to assess the quality of water bodies.The aim of this study was to investigate Ephemeroptera, Plecoptera and Trichoptera (EPT), Biotic index-Richness using macroinvertebrates to assess the water quality, with special reference to nutrient (phosphorus and nitrogen) levels in the Devolli, Shkumbini and Osumi rivers. Our objective was to investigate the relationships between the measures of benthic macroinvertebrate communities and nutrient concentrations to assess water quality. The rivers' benthic macroinvertebrates were collected during different seasons in 2012. The biological and chemical parameters used in the current study identified them as quick indicators of water quality assessment. The total number of macroinvertebrate individuals (n = 15,006) (Osumi river: n = 5,546 organisms; Devolli river: n = 3,469 organisms; and Shkumbini river: n = 5,991 organisms), together with the EPT group (Ephemeroptera, Plecoptera, and Trichoptera), showed that the water quality at the river stations during the above-mentioned period belonged to Classes II and III (fair water quality and good water quality, respectively). The classification of the water quality was also based on the nitrogen and total phosphorus contents. The pollution tolerance levels of macroinvertebrate taxa varied from the non-tolerating forms encountered in environments with low pollution levels to the tolerating forms that are typical of environments with considerable pollution levels.

Biomonitoring of water quality of the Osumi, Devolli, and Shkumbini rivers through benthic macroinvertebrates and chemical parameters

Erzeni and Ishmi Rivers flow in central Albania. The geographical position and geologic composition of Rivers basin have a specific study importance. The areas where the Rivers flows have been areas of many changes and developments lately, influencing the aquatic ecosystem in general and mainly impacting the water quality. For the biological assessment of Rivers water quality different groups of macro invertebrates are used. They are good indicators of biodiversity and habitat quality and their presence is closely connected with the general ecological status of the river ecosystem. (Lee N. 2003). Benthic macro invertebrates are determined as crucial elements and have a great importance in the biological assessment of water quality (Water Framework Directive - WFD). In this study the water quality results are given for two years of monitoring (2011 – 2012) in three sampling stations for each River in Albania. The paper presents the aquatic ecosystem situation based on data gathered on insect and invertebrate fauna. From the analyses of data is important to mention the presence of benthic sensitive organisms (Environmental Protection Agency- USA) in the sampling stations in Erzeni River, while this group of invertebrates is missing in monitoring stations in Ishmi River. Two other groups, benthic invertebrates with a medium tolerance toward pollution and tolerant taxons were present in both Rivers. Beside the classification of species according their tolerance, Biotic Index is calculated based on all the macro invertebrate groups found in each River.

Biological assessment of water quality inErzeni and Ishmi Rivers in Albania, using asbiological indicators, different groups ofmacro invertebrates, during 2011 - 2012

Aquatic macro invertebrates are good indicators of biodiversity and habitat quality (Lee N. 2003).These insects inhabit aquatic ecosystems for most of all their lives and are sensitive to different chemical and physical conditions (Cardoso et al, 2005; Annonimous, 2006) their survival is closely linked with environmental conditions.Therefore their presence is an important indicator of watershed health (Lee & Rudd, 2003). During last years different studies and data are collected on Albanian rivers water quality. Our study aim to give a preliminary situation of Albanian rivers water quality based on the data gathered on insect and invertebrate fauna. In our study EPT, SEPT, (Bode et al. 1995, Parker & Salansky, 1998) TV. (Reiss et al., 2000) and EPT Biotic Index (Schmiedt et al; 1998; Somers et al, 1998) was evaluated for the rivers of Buna, Shkumbini and Vjosa (north center and south Albania). The results show that SETP 19 and EPT Biotic Index 2.5 for Buna River; for Vjosa River ETP 15 and EPT Biotic Index 2.9; for Shkumbini River SETP 13 and EPT Biotic Index 2. Based on this data we can say that the water quality of those rivers is still very good.

Preliminary data onn using insects and other invertebrate groups as biological indicators of water quality in some albanian rivers

This study was carried out on Shushica River, a branch of Vjosa River, located in the Vlora district south west Albania, during 2017. This river flows from the Kuci area parallel with the main road in all her longitude. The recent process of rehabilitation of this road and the process of human population growth in this region is expected to have a severe impact in watershed and water quality of this area through reduction of microhabitat diversity and its associated biodiversity. During this study three stations were chosen randomly on the stream and samples were taken seasonally (Spring and Summer 2017). Here we are presenting the preliminary data based on the identification of a total number of 841 organisms. The collected samples include organisms from class: Annelid (Oligochaeta) and Insecta. Insects are dominating throughout all the sampling period. Between organisms of class Insecta dominant are the families Chironomidae and Simulidae (Diptera), Elmidae (Coleoptera), Hydropsychidae (Trichoptera), and Heptagenidae (Ephemeroptera). Based on the collected data the EPT index (abundances in the sample of the organisms belonging to the orders Ephemeroptera, Plecoptera and Trichoptera in comparison to the total number of organisms in the sample) was calculated. Based on the published data of different recent studies the water quality of the river is related directly with the higher relative abundance of those taxa.

 Compliance with the Water Framework Directive has not yet been met by Albania, and further efforts are needed to achieve this goal, including the implementation of an extensive programme of monitoring of surface and groundwater bodies. Benthic macroinvertebrates are an integrated element of this monitoring programme whose results are being used to assess the achievement of the Water Framework Directive objectives. This study has been carried out strictly following protocols and methodologies of the Water Framework Directive. The biological assessment took place in 2017 at 11 monitoring stations along the Drin River in Albania. Sampled specimens have been used to assess the water quality along the Drin River Basin through a set of indices’ calculations per each group of indicators. A total of 41 benthic invertebrate taxa were used to calculate the biotic indices, finding out only 3 monitoring stations with a good status of water out of 11 monitoring stations assessed in our study; water quality in 8 monitoring stations is classified as a moderate or poor status. Statistical analysis has been carried out to identify the trend of benthic invertebrates from one sampling point to another and the factors influencing the similarity between monitoring stations and benthic invertebrate families.
