Data Descriptor: A European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins

Tunca, Hatice (NATURE PUBLISHING GROUP, 2018)

Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ...
Phytoplankton dynamics and structure, and ecological status estimation by the Q assemblage index: a comparative analysis in two shallow Mediterranean lakes

Ongun Sevindik, Tuğba; Tunca, Hatice (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2017)

The aim of this research was to compare the phytoplankton structure on the basis of environmental variables and test the Q assemblage index based on phytoplankton functional groups in two shallow Mediterranean lakes [ Lake ...
Preliminary study on the effects of heavy metals on the growth and some antioxidant enzymes in Arthrospira platensis-M2 strain

Burcin Onem; Doğru, Ali; Ongun Sevindik, Tuğba; Tunca, Hatice (WILEY, 2018)

In this study, we have analyzed superoxide dismutase (SOD), ascorbate peroxidase (APX) and glutathione reductase (GR) activities, biomass accumulation and chlorophyll-a content in the Arthrospira platensis-M2 strain grown ...
Synthesis, characterization, and determination of genotoxic effect of a novel dimeric 8-hydroxyquinoline Cd(II) SCN complex

Tunca, Hatice; Berber, Ahmet Ali; Kubra Canakci; Tuna, Murat; Yıldız, Salih Zeki; Aksoy, Hüseyin (TAYLOR & FRANCIS LTD, 2017)

In this study, a Cd(II) complex was synthesized using 8-hydroxyquinoline and thiocyanate as the ligands and structurally characterized with the combination of FTIR, H-1-NMR, C-13-NMR, UV-vis, and MS spectral data. Then, ...
Temperature Effects Explain Continental Scale Distribution of Cyanobacterial Toxins

Ongun Sevindik, Tuğba; Tunca, Hatice (MDPI, 2018)

Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing ...
The effects of a water-soluble alpha tetra-substituted zinc phthalocyanine derivative on Arthrospira platensis-M2 strain

Günsel, Armağan; Tunca, Hatice; Bilgiçli, Ahmet Turgut; Ali Dogru; Yaraşır, Meryem Nilüfer; Tugba Ongun Sevindik; Sukruye Er (WORLD SCI PUBL CO INC, 2018)

In this study, we have analyzed the effect a newly synthesized water-soluble alpha tetra-substituted zinc phthalocyanine (Pc) compound on superoxide dismutase (SOD), ascorbate peroxidase (APX) and glutathione reductase ...
