The growth of tanypus punctipennis meigen (diptera, chironomidae) larvae in laboratory conditions and the effects of water temperature and ph

Recent taxonomic studies suggest that findings of larval chironomids should be supported also by adult findings in order to obtain more robust and reliable results on the studied group. Moreover identifications of larvae of some species can be made to genus level only due to similarities of some larval characteristics in different species. In such cases, species level identifications can be achieved by the growth of larvae in laboratory conditions. Also, larval culturing under optimum growth conditions will not only make it easy to provide materials for experimental studies and but also achievement of larvae with a higher biomass value to be used as food in the sector. In this study, Tanypus punctipennis Meigen (Diptera, Chironomidae), a very common species in Turkish Thrace, was used as the model organism for culture studies. Individual larvae were cultured from third instar stage to adult form under laboratory conditions. A simple and cheap method is offered for experimental studies on larval growths of chironomids and the effects of water temperature and pH, both with very important roles in larval culturing, were determined. The overall results of laboratory tests showed that the temperature value of 25°C and 7-8 pH interval were the optimal laboratory conditions for culture of T. punctipennis larvae.Son zamanlarda yapılan taksonomik çalışmalarda larval chironomidlerin erginleri ile birlikte değerlendirilmesinin daha güvenilir sonuçlar verdiği belirtilmektedir. Ayrıca, bazı türlerin teşhisleri, larval safhadaki bazı karakterlerin türler arasındaki benzerlikleri nedeniyle ancak cins düzeyine kadar yapılabilmektedir. Bu durumda larvaların laboratuvar koşullarında yetiştirilerek erginleştirilmesi sayesinde tür düzeyinde teşhisleri mümkün olabilmektedir. Ayrıca, uygun yetiştirme koşulları belirlenerek yapılan larva yetiştiriciliği, bir taraftan deneysel çalışmalarda gerekli materyalin eldesi için kolaylık sağlarken, diğer taraftan balık yemi sektöründe daha ileri instar evrelerine ve dolayısıyla yüksek biyomass değerine hızla erişecek larva temini için de yararlı olacaktır. Bu araştırmada, yetiştirme çalışmaları için model tür olarak Trakya’da oldukça yaygın olan Tanypus punctipennis Meigen (Diptera, Chironomidae) larvaları kullanıldı. Bireyler, üçüncü instar safhasından ergin forma erişinceye dek laboratuvar koşullarında yetiştirildi. Böylelikle, laboratuvar koşullarında larval chironomid yetiştirme amaçlı çalışmalar için basit ve ucuz bir yöntem deneyimlenerek sunulurken, larvaların yetişmesinde oldukça önemli rolü olan su sıcaklığı ve pH gibi çevresel faktörlerin etkileri de araştırıldı. Çalışmanın sonucunda T. punctipennis larvalarının gelişiminde 25°C ve 7-8 pH aralığının en uygun koşullar olduğu belirlendi

Gala Gölü (Edirne/Türkiye) fitoplanktonunun mevsimsel dağılımı

This study was performed from March 2004 to February 2005 in 4 stations in Gala Lake, a shallow lake located inside Gala Lake National Park in Meriç Delta. Water samples were taken from the lake in order to determine the phytoplankton present in the lake and to perform physicochemical analysis. A total of 112 taxa from 5 divisio were identified during the study period. Chlorophyta was the most diversed group in the lake with 47 taxa and diatoms were found to have the highest cell counts with a mean value of 670011 cell L-1. The general pattern of seasonal succession in phytoplankton of the lake was represented with Chlorophyta in June and with Cyanophyta in September and Diatoms were the dominant group of the lake in all other months. A spatial heterogeneity was observed in the lake where a slight Microsystis spp. increase occurred in early autumn months. Comparison with former phytoplankton data showed distinct differences in terms of the qualitative and quantitative composition of the phytoplankton community of Lake Gala, which indicates lake deterioration.Bu çalışma Meriç deltasında Gala Gölü Milli Parkı içerisinde bulunan ve sığ bir göl olan Gala Gölü’nde belirlenen 4 istayonda Mart 2004-Şubat 2005 tarihleri arasında yapılmıştır. Gölden alınan su örneklerinde fitoplanktonun belirlenmesinin yanı sıra bazı fizikokimyasal analizler de yapılmıştır. Çalışma süresince 5 divizyoya ait toplam 112 taxa gözlemlenmiştir. En fazla tür sayısının 47 tür ile Chlorophyta’ya ait olduğu gölde Diatomlar ortalama 670011 hücre L-1 ile en çok hücre sayısına sahip grup olmuştur. Göl fitoplanktonunun mevsimsel süksesyonunda genel yapı Haziran ayında Chlorophyta, Eylül ayında ise Cyanophyta hakimiyeti şeklindedir. Bu ayların dışında tüm örnekleme periyodu boyunca Diatomlar gölün hakim organizmaları konumundadır. Bunun yanısıra sonbahar aylarında hafif bir Microsystis spp. çoğalmasının meydana geldiği gölde fitoplanktonun yıl boyunca değiştiği gözlemlenmiştir. Daha önceki veriler ile karşılaştırıldığında Gala Gölü fitoplanktonunda nitel ve nicel olarak farklılıklar tespit edilmiştir

Application of Hypothetical Ecological Risk Analysis to Sustainable Usage of Possible Winter Recreation Areas in Seyhan Basin (Türkiye)

In this study, the long-term suitability of the area proposals for winter recreation activities in the Sey-han Basin (Türkiye), which is located in the Mediterranean and Central Anatolia regions and includes alargepartoftheTaurusMountains,wereexaminedecologically.Forthispurpose,thepredictedglobal warming scenarios in the basin and the anthropogenic impacts arising from the planned rec-reation 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 possiblefactorsweredeterminedasflood(S1),drought(S2),sedimentation(S3),aquaticnutrients(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 hypothet-ical 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 fu-ture 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
