Taxonomical and numerical comparison of epipelic algae from balik and uzun lagoon, Turkey

The epipelic algae of Balik lagoon and Uzun lagoon were investigated from May 2003 to December 2004. A total of 106 taxa were identified. Of these, 85 were found in Balik lagoon and 78 were found in Uzun lagoon. Water temperature of the lagoons ranged from 6.5 to 24.5oC during the sampling period. Conductivity, hardness, dissolved oxygen an pH values varied between 0.70 and 8.00 mS, 26.00 and 86.60 of, 3.50 and 9.00 mg l -1 and 7.82 and 8.70 respectively. Nitrite nitrogen, nitrate nitrogen, chloride, phosphate phosphorus and sulphate concentrations in the water were also measured and ranged from 0.01 to 0.14, 0.01 to 0.24, 2.41 to 48.70, 0.01 to 0.12 and 54.00 to 104.40 mg l -1 respectively. Species richness (d), diversity (Shannon – Weaver, H’) and evennes ( J’) were calculated for epipelic algae and the findings showed similar oscillations throughout the research period. Cluster analyses and multidimensional scaling (MDS) revealed a similar distribution pattern of epipelic algal flora in both lagoons

New records for marine phytoplankton of Turkish seas from southern Black Sea coasts

Six new records for Turkish Marine Phytoplankton are reported first time from southern Black Sea coastal waters. One of these taxa was from Zygnematophyceae, four were from Bacillariophyceae and one was from Fragilariophyecae.Güney Karadeniz kıyısal sularında Türkiye denizleri fitoplanktonu için 6 yeni kayıt ilk kez rapor edilmiştir. Tanımlanan taksonlardan biri Zygnematophyceae, dördü Bacillariophyceae ve biri Fragilariophyecae sınıflarına aittir

Gökçeada Salt Lake: a Case Study of Seasonal Dynamics of Wetland Ecological Communities in the Context of Anthropogenic Pressure and Nature Conservation

Gökçeada Salt Lake (GSL) (Gökçeada Island, North Aegean Sea) is an important wetland area situated on established birdmigratory routes. The waterbody is subject to significant variability in seasonal water quality and species diversity. Monthlyobservations indicate that a total of 29 waterbird species were present during 2015–2016. Rainfall was observed to influencewaterbird abundance. There was also a strong correlation between waterbird and zooplankton species diversity, with waterquality a further influencing factor. The seasonal abundance of 78 other aquatic species was also investigated. Spring and fallseasonal eutrophication, as a consequence of canal construction and suspected warming due to climate change has causedchanges in Chlorophyll-a, dissolved oxygen, biological oxygen demand levels and grazing habits of aquatic species. Here, wepropose GSL as a coastal lagoon model for a hydrodynamically sensitive habitat undergoing significant change from thecombined threats of heavy metal pollution from a waste management facility, pesticide use for tourism and agriculture activityand wider climate impacts. We conclude that our results provide a paradigm for broad-scale monitoring programs encompassingall components of the wetland ecosystem under anthropogenic and climate change pressure, thus providing a tool to support andinform essential management and rehabilitation plans

SPECIES DIVERSITY IN LENTIC, LOTIC, MARINE AND TERRESTRIAL BIOTOPES OF GOKCEADA SALT LAKE WETLAND (CANAKKALE, TURKEY)

This study was carried out to provide detailed information on species diversity and community structure of Gokceada Salt Lake Wetland (brook feeding the lake, neighboring sea and terrestrial area around the wetland). Aquatic species diversity (algae, invertebrates, and fish) at 9 different stations in freshwater, brackish water and marine ecosystems, and terrestrial species diversity (plants, amphibians, reptiles, birds and mammals) in the surrounding wetland were studied seasonally in 2016. A total of 195 taxa of terrestrial vascular flora and 134 species of aquatic flora (97 species of phytoplankton, 37 species of benthic algae); a total of 23 macrobenthic invertebrate taxa from the lake and 131 invertebrate species from the sea were identified. Also, 4 fish, 14 reptiles, 3 amphibians and 71 bird species were observed in the study area. While one species of phytoplankton was determined as a new record for the Turkish aquatic flora, a total of 71 marine invertebrate species were reported for the first time in the marine fauna of Gokceada. The obtained data will not only provide a solid basis to expand the understanding of the island's ecosystem, but also will serve as an important tool in the action plans for wetland conservation
