(Central Fisheries Research Inst, 2010) Camur-Elipek, Belgin; Arslan, Naime; Kirgiz, Timur; Oterler, Burak; Guher, Huseyin; Ozkan, Nurcan
In order to determine the relationships between the dynamics of benthic macroinvertebrates (both species number and individual number) and environmental variables, sampling was made at four different stations at monthly intervals during a year between March 2004 and January 2005 of Lake Gala which is a part of an important wetland and a national park in European part of Turkey (Enez/Edirne). Altogether, a total of 49 zoobenthic taxa which were grouped as Oligochaeta, Chironomidae, and Varia, comprised of 1,628 individuals in per m(2) at average were recognised in the sampling stations of the Lake. The present study showed that larval chironomids comprising 57% abundance of the total specimens are the biggest part of benthic macroinvertebrates. It is followed by oligochaetes and the group varia comprising 34% and 9% abundance, respectively. Also, it was seen changing that the composition of zoobenthic group dominancy in the Lake as time passes. Furthermore, according to Shannon-Wcaner index, species diversity for zoobenthic macroinvertebrate fauna of the lake was found as H'=1.21 at average. Also, similarities of the sampling stations and months, both the dynamics of benthic macroinvertebrates and physicochemical features were evaluated by using Bray-Curtis similarity index. According to Spearman correlation index, relationship between the number of individuals and some physicochemical variables such as temperature, turbidity (light permeability), and depth of the lake was determined statistically significant.
Annotated catalogue of Enicocephalomorpha, Dipsocoromorpha, Nepomorpha, Gerromorpha, and Leptopodomorpha (Hemiptera: Heteroptera) of Turkey, with new records
(Magnolia Press, 2011) Fent, Meral; Kment, Petr; Camur-Elipek, Belgin; Kirgiz, Timur
An annotated check-list of the aquatic and semi-aquatic bugs of the infraorders Enicocephalomorpha, Dipsocoromorpha, Nepomorpha, Gerromorpha, and Leptopodomorpha of Turkey and its geographical parts (Turkish Thrace [i.e., European Turkey] and Anatolia [i.e., the Asian Turkey]) is presented. The nomenclatoric history of Alpagut Kiyak, 1995 (= Harpago Linnavuori, 1951, = Raunocoris Baena & Alonso-Zarazaga, 2009) is reviewed, its gender is fixed, and two new combinations are proposed: Alpagut maroccanus (Wagner, 1960) comb. nov., and Alpagut medius (Rey, 1888) comb. nov. The list is based on a survey of all published records as well as on examination of collection material, including recent material collected in the poorly explored Turkish Thrace. The following numbers of species are accepted as occurring in Turkey: Enicocephalomorpha-1 species (Asian Turkey only), Dipsocoromorpha-2 species (Asian Turkey only), Nepomorpha-49 species (29 in European and 47 in Asian Turkey), Gerromorpha-27 species (10 in European and 25 in Asian Turkey), and Leptopodomorpha-21 species (6 in European and 20 in Asian Turkey). Forty species are known from both European and Asian Turkey, whereas 5 are recorded only from European Turkey and 55 only from Asian Turkey. Eight species and subspecies, Micronecta scholtzi (Fieber, 1860), Hesperocorixa sahlbergi (Fieber, 1848), Sigara iranica Lindberg, 1964, Hebrus ruficeps Thomson, 1871, Velia affinis filippii Tamanini, 1947, Velia rhadamantha rhadamantha Hoberlandt, 1941, Gerris kabaishanus Linnavuori, 1998, and Saldula pilosella pilosella (Thomson, 1871), are reported from Turkey for the first time; and four species, Sigara scripta (Rambur, 1840), Corixa punctata (Illiger, 1807), C. panzeri (Fieber, 1848), and Gerris argentatus Schummel, 1832, are new records for Turkish Thrace.

Application of Hypothetical Ecological Risk Analysis to Sustainable Usage of Possible Winter Recreation Areas in Seyhan Basin (Turkiye)
(Istanbul Univ Press, Fac Aquatic Sciences, 2022) Yeler, Okan; Aydin, Gazel Burcu; Camur-Elipek, Belgin; Berberoglu, Suha
In this study, the long-term suitability of the area proposals for winter recreation activities in the Seyhan Basin (Turkiye), which is located in the Mediterranean and Central Anatolia regions and includes a large part of the Taurus Mountains, were examined ecologically. For this purpose, the predicted global warming scenarios in the basin and the anthropogenic impacts arising from the planned recreation areas were evaluated for the upper basin (recreation areas) and lower basin (water resources, agricultural lands, and settlements) using a hypothetical risk analysis. For this purpose, multispectral images were obtained by using Landsat 8 Oli Multispectral images of the snow areas in the region in January-February-March 2019, and a hypothetical ecological risk analysis was created considering a total of 5 pressure factors originating from global climate change and anthropogenic effects. These possible factors were determined as flood (S1), drought (S2), sedimentation (S3), aquatic nutrients (S4), and tourist density (S5). The effects of these factors on a total of four features (C1: water quality, C2: fauna-flora, C3: agricultural areas, and C4: settlements) in the region were evaluated by hypothetical grading based on the literature. According to the hypothesis results obtained by the formula and statistical calculations, it was determined that the flood factor (S1) that will occur due to possible snow melt due to global climate change in the winter recreation areas in the studied region is the most significant factor limiting the sustainable usage of the Basin. For this reason, it has been emphasized in this study that the possibility of regions being exposed to the effects of climate change in the future should be taken into account, especially when planning for winter recreation areas. At the end of this study, it was concluded that the ecological balance analysis of basins is important, especially in terms of ensuring the long-term sustainable use of winter recreation areas.
Benthic macrofauna in Tunca River (Turkey) and their relationships with environmental variables
(Wiley-V C H Verlag Gmbh, 2006) Camur-Elipek, Belgin; Arslan, Naime; Kirgiz, Timur; Oterler, Burak
The numerical and proportional distributions of benthic macroinvertebrates in Tunca (Tundja, Tundzha) River (Edirne/Turkey) were determined from July 2002 to June 2003 at monthly intervals at four different stations. It was found that the benthic macrofauna consisted of 63% Oligochaeta, 24% Chironomidae larvae, and 13% Varia by numbers. According to the Shannon-Wiener index, Tunca River had a diversity of 1.36; station 2 and September were found to have the highest diversity while station 4 and December to have the poorest. According to Bray-Curtis similarity index, stations 2 and 3 and April and May were found to be the most similar to each other while stations 1 and 4 and August and January were found to be the most different from each other for the dynamics of the benthic macrofauna. Also some physicochemical parameters of the water (water temperature, electrical conductivity, pH, dissolved oxygen, chloride, total hardness, NO3--N, NO2--N, sulfate, phosphate, biochemical and chemical oxygen demands) were analyzed. Pearson correlation index supported the relationships between the dynamics of organisms and physicochemical variables. The relation between the number of macroinvertebrates and pH (r = +0.57, P < 0.05) was direct proportional while the relation between the number of macroinvertebrates and NO3--N (r = -0.99, P < 0.05) was inverse proportional. Furthermore, the Chironomidae larvae of Bryophaenocladius muscicola and Mesosmittia flexuella were new records for Turkish Thrace region. High pH and supersaturated oxygen levels, hard water quality, second quality levels of NO3--N, BOD, COD and fourth quality levels of NO2--N as well as the density of 490 individuals m(-2) for 124 taxa and the diversity of 1.36 showed that similar studies should be repeated periodically in Tunca to determine the future of the river.
Benthic Macroinvertebrate Diversity of Rice Fields in the Meric-Ergene River Basin, Thrace, Turkey
(Inst Zoology, Bas, 2019) Aydin, Gazel Burcu; Camur-Elipek, Belgin
Rice fields are temporary wetland agro-ecosystems that could be inhabited by benthic macroinvertebrates. A survey of benthic macroinvertebrate diversity of rice-fields in the Meric-Ergene River Basin, an important rice-production area in Turkey, was carried out during the cultivation cycle (April - October 2016). We identified 69 benthic macroinvertebrate taxa in the studied area, majority of them with a potential to represent food resources for fish. Totally, 51 species were identified at the species level; in addition to them, other invertebrates were identified at the levels of superior taxa: seven genera, eight families, one order, one class and one phylum. Of the sampled taxa, 74% were arthropods (representing 21 families in five classes). Seasonal colonisation and succession of benthic macroinvertebrates during rice cultivation cycle followed one another, being also regulated by predation. We conclude that strategies of sustainable management of rice fields should be planned together by biologists and agroecologists, and propose alternative approaches to utilise the rice field apart from rice production.

(Ege Univ, 2008) Tas, Menekse; Kirgiz, Timur; Arslan, Naime; Camur-Elipek, Belgin; Guher, Huseyin
This study was performed to determine Oligochaeta fauna and some physicochemical features of Corlu Stream which is the large part of Meric-Ergene River Basin. A total of 9 Oligochaeta species belonging to Tubificidae (4 species) and Naididae (5 species) was recorded in the study during seasonal sampling carried out between 1990 and 1991. Furthermore, some physicochemical parameteres (pH, conductivity, dissolved oxygen, biological and chemical oxygen demands) in the stream which was under the pressure of intensive pollution because of urban and industrial wastes, were measured. To determine the changes in species composition and pollution level one more sampling was made in 2008. Also, some physicochemical features (pH, temperature, dissolved oxygen, nitrite, nitrate, sulphate, phosphate, H2S, Suspended Solid Matter) were measured beside Oligochaeta sampling. It was observed that number of total oligochaeta species was decreased to 4 and the quality of water in the stream was further deteriorated.
Comparative analysis of chemical and bacterial distribution of coastal lagoons and freshwater lakes in Turkish Thrace
(Univ Autonoma Metropolitana-Iztapalapa, 2018) Altinoluk-Mimiroglu, Pinar; Camur-Elipek, Belgin
Background. Microbial contamination of water bodies is causing major environmental and public health concerns in developing countries. Bacterial inclusion of inland waters can be of allochthonous and/or autochthonous origins. Goals. The aim of this study was to determine and compare the microbial contamination with environmental factors controlling colonization of bacteria in lagoon-lakes and freshwater lakes. Methods. Two lagoon-lakes and two freshwater lakes in Turkish Thrace were chosen and sampling was undertaken from October 2014 to August 2015 at seasonal intervals. While total heterotrophic bacteria, E. coli, coliform, and fecal coliform bacteria distributions from allochthonous and autochthonous origins were determined, environmental conditions of the ecosystems were also measured. While the Bray-Curtis Similarity Index and the Correspondence Analysis with Abundance Plot Analyses were used to determine the similarities of the sampling habitats, the Spearman's Correlation Index was applied to clarify relationships between the environmental variables and the bacterial distribution. Results. The bacterial distribution was positively related to dissolved oxygen in one of the sampled lagoon-lakes (r = 1.0, p < 0.01) and negatively correlated with total dissolved solids and salinity in one of the sampled freshwater lakes (r = -0.95, p < 0.01; r = -0.80, p < 0.05, respectively). Conclusions. This research indicated that the saline water of the lagoon-lakes has limited the number of bacteria when compared with freshwater lakes.

(Gazi Entomological Research Soc, 2021) Aydin, Gazel Burcu; Camur-Elipek, Belgin; Topkara, Esat Tarik
In the present study, adult specimens belonging aquatic/semi-aquatic coleopteran collected from 1986 to 2002 in Turkish Thrace were evaluated taxonomically. Altogether, a total of 23 species belonging to the families Dytiscidae, Haliplidae, Noteridae, Gyrinidae, Helophoridae and Hydrophilidae were determined. A total of 12 species Hydaticus (Hydaticus) aruspex Clark, 1864, Aulonogyrus concinnus (Klug 1834), Cercyon (Cercyon) littoralis Gyllenhal 1808, Gyrinus (Gyrinus) distinctus Aube 1836, G. (Gyrinus) substriatus Stephens 1829, Haliplus (Liaphlus) flavicollis Sturm 1834, Helophorus (Helophorus) grandis Illiger 1798, Hydrochara flavipes (Steven 1808), Laccobius (Laccobius) minutus (Linnaeus 1758), Laccophilus hyalinus (De Geer 1774), Platambus maculatus (Linnaeus 1758), Rhantus (Rhantus) suturalis (MacLeay 1825) were determined for the first time from Turkish Thrace. The aquatic habitat distributions of the species were also compared by the statistically using Shannon-Wiener diversity index and Bray-Curtis similarity index.
Distribution of the Ponto-Caspian Species Pontogammarus robustoides (Sars, 1894) (Amphipoda) in the Inland Waters of Turkey
(Inst Zoology, Bas, 2020) Arslan, Naime; Camur-Elipek, Belgin; Mercan, Deniz
Up to now, thirteen Ponto-Caspian amphipod species belonging to seven genera have been recorded in Turkey. One of them is Pontogammarus robustoides which is known as an invasive Ponto-Caspian species in several European countries. The species was reported for the first time in Turkey in 1964, and since then has been found in 12 lakes and dam lakes located in the Marmara, Aegean and Thrace regions. In this study, materials collected during different study periods were examined and P. robustoides was detected at eight new localities: the lakes Akgol and Poyrazlar, the reservoirs Demirkopru, Caybogazi and Gordes, and the rivers Cekerek, Kocacay and Bakircay. In addition, P. robustoides is reported for the first time from the Central Anatolia and Mediterranean regions of Turkey. Our results indicate that this species has expanded its distribution area in many freshwater systems in Turkey. However, it has not been reported yet from eastern and southeastern regions of Turkey. Therefore, detailed studies dealing with distribution pattern and population status of this Ponto-Caspian amphipod are needed.

(Inst Zoology, Bas, 2011) Guher, Huseyin; Erdogan, Sevil; Kirgiz, Timur; Camur-Elipek, Belgin
In this study, carried out at monthly intervals in four different stations between March 2004 and January 2005, it is aimed to have new knowledge on the dynamics of zooplankton communities and the effects of physical-chemical values of the Lake Gala. As a result of the study, a total of 76 species have been identified as 50 species belong to Rotifera, 15 species - to Cladocera, and 11 species - to Copepoda. Of these species Proalides tentaculatus de Beuchamp, 1907, Itura myersi WULFERT, 1935, Asplanchnopus hyalinus (HARRING, 1913) are found only in Turkish Thrace. As a result of quantitative evaluation of zooplankton samples, while an average of 35 334 ind./m(3) Rotifera, 19 305 ind./m(3) Cladocera, 72 369 ind./m(3) Copepoda was found an average of 127 008 ind./m(3) zooplankton organisms have been determined in the lake. According to the results of PCA analysis, when looking at the seasonal distribution of zooplankton species, it is seen that species assembled to form three groups as species which appear in spring, summer and winter. According to the results of RDA analysis, correlation (for RDA axis 1 0.956, for RDA axis 2 0.925) between zooplankton organisms and environmental variables being so high shows that Water tem, EC, SO4, Ca, pH, Chl-a, Secchi and PO4, are significant (p = 0.0020) factors determining the distribution of zooplankton organisms in the Lake Gala.
Ecological Analysis of Chironomid Larvae (Diptera, Chironomidae) in Ergene River Basin (Turkish Thrace)
(Central Fisheries Research Inst, 2010) Ozkan, Nurcan; Moubayed-Breil, Joel; Camur-Elipek, Belgin
In the present study, chironomid larvae were sampled periodically between the years 1995-96 during the one year at eight different localities of Ergene River Basin. A total of 60 chironomid taxa (325 individuals/m(2)) were recorded in the River and its tributaries (Ergene River Basin) during the sampling period. Also, it evaulated the larval chironomid assemblages in Meric-Ergene River Basin which is amongst the most important wetland area in European part of Turkey. Furthermore, it determined the physicochemical properties of the water to analyse the relationships between species composition of chironomid communities and environmental parameters. Structure of sediment at each sampling station of Ergene River Basin was revealed to determine the substratum preference of the larvae. It was that found sediment nutrient enrichment strongly influenced chironomid assemblage structure. Furthermore, main results due to species diversity, density of populations, similarities for the sampling stations and the substratum types were discussed. According to Shannon index, species diversity of the Basin was found as H'=1.41 at average. Also, Spearman index has indicated that significant correlations were found between chironomid larval densities and some environmental variables such as conductivity (r=-0.708), dissolved oxygen (r=+0.810), biological oxygen demand (r=+0.822), and chemical oxygen demand (r=+0.805) for P < 0.05.
Evaluation of ecological risk analysis for benthic macroinvertebrates in paddy fields in the Meric-Ergene River Basin (Turkish Thrace)
(Walter De Gruyter Gmbh, 2022) Aydin, Gazel Burcu; Camur-Elipek, Belgin
Benthic macroinvertebrates are very important components of aquatic environments, and monitoring their population dynamics helps us understand the effects of environmental factors on ecosystems. This study aimed to determine the dynamics of benthic macroinvertebrate fauna in paddy fields in the Meric-Ergene River Basin (Turkish Thrace region) by investigating some physicochemical environmental parameters that may affect its distribution. For this purpose, water and sediment samples were collected from paddy fields in the study area during the cultivation season, including spring, summer and autumn of 2016, taking into account the water resources that supply the rice fields (artesian water, the Meric River, the Ergene River and Meric-Ergene mixed water). A total of 47 taxa (on average 8953 individuals per m(2)) were identified at the study sites. Water samples were analyzed to determine water temperature, pH, conductivity, salinity, total dissolved solids, calcium, magnesium, total hardness, nitrite nitrogen, nitrate nitrogen, phosphate, sulfate, dissolved oxygen and pesticides, and sediment samples were analyzed to determine the content of some heavy metals, including Cd, Ni, Cu, and Mn. The biological risk index (mERM-Q) and the potential ecological risk index (RI) were applied to the data and a hypothetical ecological risk analysis was conducted using our data and data available in the literature to assess the ecological risk profile of the ecosystem based on benthic macroinvertebrates. To this end, environmental factors were grouped based on the literature as heavy metals (S1), nutrients (S2), other physicochemical parameters (S3) and pesticides (S4), while organisms were grouped as Oligochaeta, Chironomidae, Insecta and others based on the dynamics of benthic macroinvertebrates to assess pressure factors. As a result, pesticides (S4) were found to exert the strongest ecological pressure on benthic macroinvertebrate fauna in paddy fields in the Meric-Ergene River Basin.
First observations in Turkish Thrace on water mite larvae parasitism of Ranatra linearis by Hydrachna gallica (Acari: Hydrachnidia)
(Walter De Gruyter Gmbh, 2013) Zawal, Andrzej; Camur-Elipek, Belgin; Fent, Meral; Kirgiz, Timur; Dzierzgowska, Kinga
Many aquatic insect species, including aquatic Hemiptera, are parasitized by water mite larvae. Although this situation may cause damaging impacts to the hosts, the mites can disperse and colonize new localities in this way. Little is known about the frequency of water mite ectoparasitism amongst the aquatic Hemiptera in Turkey. In this study, larval water mite parasitism on aquatic Hemiptera, which have been collected from different localities in Turkish Thrace, was evaluated. It was found that only nine individuals, belonging two different species in a total of 367 hemipteran specimens, were parasitized by larval water mites. Furthermore, variations in sizes and shapes of the mites on the waterscorpion Ranatra linearis Linne, 1758 and Nepa cinerea Linne, 1758 were determined. These are the first records for larval mite parasitism on R. linearis and N. cinerea in Turkish Thrace.

The new species belongs to Gammarus pulex- group and is the fourth blind species of the group reported from Europe and Turkey. A detailed morphological description and illustrations of the new species are given and differences from related species are discussed. In addition, a key to the blind/eyeless species of Gammarus genus of Europe is presented.
Observations with a different approach to morphological colour variation in an isopod population (Crustacea: Isopoda)
(Versita, 2009) Camur-Elipek, Belgin
Morphological colour variation in Idotea baltica basteri Audouin, 1827 (Isopoda: Crustacea) is reported for the first time on populations from a brackish water lake (Kucukcekmece Lagoon) in Turkey. According to pigmentation characteristics, the isopods were described and sorted to ten different colour morphs which are named as maculata, maculata-lineata, uniformis, uniformis-lineata, immaculatum, immaculatum-lineata, nigrum, nigrum-lineata, albafusca, and albafusca-fasciatum. The similarity of the morphs was compared by defining digit codes to some of the visual pigmentation characteristics and calculating the Bray-Curtis similarity index of the colour morphs. The albafusca and albafusca-fasciatum forms were found to be the most similar to each other (similarity 96%), whereas immaculatum forms were considered the most different from maculata-lineata (similarity 50%). The morphs named maculata and maculata-lineata, having the highest abundance with 70%, belong to the most successful forms which may achieve crypsis by background matching in their living habitat in Kucukcekmece Lagoon which has sandy and rocky bottom surface area.
Qualitative and quantitative evaluation of water resources that feed into the National Park Igneada Longoz Forests (Turkish Thrace) by using physico-chemical and biological analyses
(Univ Autonoma Metropolitana-Iztapalapa, 2015) Camur-Elipek, Belgin; Kirgiz, Timur; Oterler, Burak; Tas, Menekse
In this study, some physico-chemical and biological features of the water resources that feed three alluvial longose groves (are also known as Longoz) which are important wetlands in the National Park Igneada Longoz Forests including a lot of different ecosystems were investigated. In order to assess the water quality, a total of eight running water resources were sampled within four different seasons and two lakes were sampled at dry and wet seasons in 2008-2009. While some water resources were found to have high quality levels for some physico-chemical findings, the results were also supported by using EPT (Ephemeroptera Plecoptera Trichoptera) index. Furthermore, the cluster analysis, correspondence analysis, and Pearson correlation index were used to determine the relationships between the data. As a result, although a lot of sampled water resources that feed into the National Park area has been found to have good quality level, it was also observed that the area have been under the negative effects of humans. Therefore, at the end of this study, it was also made some suggestions for sustainable usage of this special area.
A Study on the Odonate Larvae of Turkish Thrace: with Larval Identification Keys to the Considered Taxa
(Gazi Entomological Research Soc, 2010) Hacet, Nurten; Camur-Elipek, Belgin; Kirgiz, Timur
The present paper focuses on odonate larvae (damselfly and dragonfly) within Turkish Thrace. A total of 26 spp. were recorded based on larval specimens collected from the region during sampling period between years 1982 and 2009. New localities for the odonate species, except Caliaeschna microstigma, Gomphus flavipes, Cordulegaster insignis, and Sympetrum fonscolombii, were added to their distributional ranges inside the region. Furthermore, Anax imperator, Brachytron pratense, and Libellula fulva were recorded from the provinces where they had not previously been found. Keys including illustrations of the larvae recorded in the region were provided.
The subterranean genus Niphargus (Crustacea, Amphipoda) in the Middle East: A faunistic overview with descriptions of two new species
(Elsevier Gmbh, Urban & Fischer Verlag, 2009) Fiser, Cene; Camur-Elipek, Belgin; Oezbek, Murat
The Middle East is at the southeastern borderline of the range of the subterranean amphipod Niphargus. The review of new and published data identified two new species and set the guidelines for the future research in the area. The genus in this part of the world seems to be insufficiently studied. The taxonomic status of Niphargus valachicus, population identified as N. spoeckeri and some populations, identified as N. nadarini, need to be reviewed. According to present data, we expect the highest diversity in Western Turkey. The eventual new records of the genus in the Middle East can be expected from those areas where even the longest periods of drought in the recent geological history did not affect the water supply.

Vertical and horizontal composition of fecal pollution indicator bacteria in lotic and lentic ecosystems at Turkish Thrace
(Periodicum Biologorum, 2016) Altinoluk-Mimiroglu, Pinar; Camur-Elipek, Belgin
Background and Purpose: Although freshwater ecosystems have natural bacterial populations, their distributions are negatively affected by agricultural activities, domestic and industrial discharges. Bacterial composition at different depths can limit the usage of the water column for drinking, irrigation or other intentions. This study was designed to give similar indications concerning the nature of distribution of indicator bacteria in two different freshwater ecosystem types (lotic and lentic biotopes), and also to identify the factors that might be responsible in shaping them. Materials and Methods: For this aim, stagnant and running water resources located in Meric-Ergene River Basin at Turkish Thrace were sampled at three water depths (surface, middle, bottom) and two sediment depths (shore and bottom) between the dates October 2014 and September 2015 at seasonal intervals. While the heterotrophic bacteria, total and fecal coliform bacteria, and Escherichia coli were recorded by the CFU and MPN techniques, some features (temperature, dissolved oxygen, pH, conductivity, salinity, nutrients, ions, and elements) were also measured by classical chemical, chromatographic or spectrometric methods. Results and Conslusions: According to the data, the bacterial distribution in each ecosystem was found as similar for the bottom and the surface water columns. Results were also supported statistically by Bray-Curtis similarity index and correspondence analyse. The relationships between the bacterial distribution and environmental features were evaluated by Spearman correlation index. Consequently, it was observed that the bacterial distribution can differ in both water column/ sediment depths and lotic/ lentic ecosystems. And, it was suggested that the middle water column in each ecosystem is the most proper column for human usage.
