  Uzunçayır Baraj Gölü’nün Fitoplankton Türleri ve Fiziko- Kimyasalar Parametrelerinin Belirlenmesi

  Serdar, Osman; Kutlu, Banu; Aydin, Rahmi; Danabaş, Durali

  Uzunçayır Baraj Gölü fitoplankton dagılımı ve fiziko-kimyasal parametreleri, Mayıs 2013?Nisan 2014 tarihleri arasında incelenmis olup, elde edilen veriler tablo ve grafikler halinde sunularak, istatistiksel analizlerle degerlendirilmistir. Arastırma süresince Uzunçayır Baraj Gölü?nde sıcaklık 6,2-27,3°C; sechii disk derinligi 0,81- 11,09 m arasında; klorofil-a miktarı yüzey istasyonlarında 0-72,343 μg/L arasında; yüzey suyunda pH degeri 6,43-9; fosfor degeri yüzeyde 0-0,94 mg/L ve toplam sertlik degeri yüzeyde 90-218 mg/L arasında ölçülmüstür. ?Su Kirliligi Kontrol Yönetmeligi??ne göre Uzunçayır Baraj Gölü suyu, sıcaklık, pH, çözünmüs oksijen, nitrit azotu degerlerine göre II. sınıf su grubuna, nitrat azotu degerlerine göre ise kirlenmemis sular grubuna girmektedir. Uzunçayır Baraj Gölü?nde, Ochrophyta divizyonu (31 tür), Charophyta divizyonu (4 tür), Chlorophyta divizyonu (3 tür), Cyanobacteria (4 tür), Dinophyta divizyonu (9 tür), Euglenophyta divizyonu (2 tür) ait taksonlar tespit edilmistir. Shannon-Wiener çesitlilik analizine göre çesitlilik indeksi degerleri yüzeyde 0,48-2,48 arasında saptanmıstır. Bu degerlere göre göl suyu ?kirlenmemis ve kısmen kirlenmis alanlar? grubuna girmektedir. Uzunçayır Baraj Gölü morfometrik yapısı, su derinliginin fazla olması, klorofil-a ve toplam fosfor degerlerine göre oligotrof bir göl gibi görünse de fitoplankton yapısı, sechii diski diski derinligi ve bilesik indis degerlerine göre mezotrof bir göl olma özelligi göstermektedir

  Ecological risk assessment of heavy metals in surface sediments of northern littoral zone of Lake Cildir, Ardahan, Turkey

  Kükrer, Serkan; Seker, Sebahat; Abaci, Z. Tugba; Kutlu, Banu

  In this paper, the heavy metal levels (Cu, Pb, Zn, Ni, Mn, Fe, As, Cd, Cr, Hg), organic carbon, and chlorophyll degradation products were studied to prove their ecological effects in Lake CA +/- ldA +/- r, where fossil fuels are used as an energy source in the studied area for most of the year, and domestic waste from settlements is discharged directly into the lake. Sediment samples were collected from six sites on the northern shore of CA +/- ldA +/- r Lake, Turkey in November 2012. Enrichment (EF) and contamination factor (CF) values were determined, and Pollution Load (PLI) and Potential Ecological Risk (PER) indices were calculated. Average concentrations of heavy metals in the sediments were, in descending order, Fe > Mn > Zn > Ni > Cr > Cu > Pb > As > Cd > Hg, respectively. According to mean values, the source of these elements may be considered natural due to lack of enrichment in Cu, Pb, Zn, Ni, and Cr in the sediment samples. Regarding enrichment of As, Cd, Mn, and Hg, the highest EF belongs to Hg. PLI and PER values indicate there are moderate ecological risk in the lake.

  Investigations on the growth kinetics of hantzschia amphioxys homa lagoon by izmir bay (Aegean Sea)

  Kutlu, Banu; Buyukisik, Baha

  zschia amphiarys were investigated under continuous-light period and batch culture conditions. The optimum temperature and light intensities were found as 18 degrees C and 52 mu mol/m(2)s (saturasyon light), respectively. mu(max) and K-s values estimated for each nutrient were obtained as follows: ammonia for 1.528 day(-1) 2.959 mu g-at- NH4+-N/L, nitrate 1.22 day(-1), 7.01 mu g-at NO3- -N/L, phosphate 1.767 and 1.172 day(-1) 5.07 and 0.460 mu g-at PO4-(3)-P/L, silicate 1.141 day(-1) and 0,499 mu g-at Si/L. Carrying capacity values estimated for each nutrients were obtained as follows: nitrate 113,7 mu g chl a/L, 190.11 phosphate 113.7 mu g chl a/L, 1.798. Nitrogen limiting nutrients was found as in this study.

  Comparison of Growth Kinetics of Chaetoceros gracilis Isolated from Two Different Areas in the Aegean Sea (The Bay of Izmir and the Homa Lagoon)

  Sunlu, F. Sanem; Kutlu, Banu; Buyukisik, H. Baha

  In this study, the species Chaetoceros gracilis was isolated from two different ecosystems (sea-lagoon) in the Bay of Izmir with very different physico-chemical environmental parameters. With the batch culture experiments carried out using the small diatom C. gracilis, it is aimed to determine the physiological properties of this species and also to form a basis for model studies by parameterizing its exponential growth rates, its nutrient limiting growth rates and the Michealis-Menten curves that indicate its dependence on nutrients. The fact that it is spread in a wide variety of areas from oligotrophic regions to eutrophic regions shows that this species environmental adaptation is quite interesting.
