Öğe Gokceada Salt Lake: a Case Study of Seasonal Dynamics of Wetland Ecological Communities in the Context of Anthropogenic Pressure and Nature Conservation(Springer, 2021) Aslan, Herdem; Elipek, Belgin; Gonulal, Onur; Baytut, Ozgur; Kurt, Yusuf; Inanmaz, Ozgur E.Gokceada Salt Lake (GSL) (Gokceada Island, North Aegean Sea) is an important wetland area situated on established bird migratory routes. The waterbody is subject to significant variability in seasonal water quality and species diversity. Monthly observations indicate that a total of 29 waterbird species were present during 2015-2016. Rainfall was observed to influence waterbird abundance. There was also a strong correlation between waterbird and zooplankton species diversity, with water quality a further influencing factor. The seasonal abundance of 78 other aquatic species was also investigated. Spring and fall seasonal eutrophication, as a consequence of canal construction and suspected warming due to climate change has caused changes in Chlorophyll-a, dissolved oxygen, biological oxygen demand levels and grazing habits of aquatic species. Here, we propose GSL as a coastal lagoon model for a hydrodynamically sensitive habitat undergoing significant change from the combined threats of heavy metal pollution from a waste management facility, pesticide use for tourism and agriculture activity and wider climate impacts. We conclude that our results provide a paradigm for broad-scale monitoring programs encompassing all components of the wetland ecosystem under anthropogenic and climate change pressure, thus providing a tool to support and inform essential management and rehabilitation plans.Öğe SPECIES DIVERSITY IN LENTIC, LOTIC, MARINE AND TERRESTRIAL BIOTOPES OF GOKCEADA SALT LAKE WETLAND (CANAKKALE, TURKEY)(Parlar Scientific Publications (P S P), 2018) Aslan, Herdem; Gonulal, Onur; Can-Yilmaz, Elif; Elipek, Belgin; Baytut, Ozgur; Tosunoglu, Murat; Karabacak, ErsinThis 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.
