Özet

Summary

Wetlands are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface, or the land is covered by shallow water. Erzurum wetland on the migration route of birds in wetlands in northeastern Anatolia is an area with a very important and rich ecosystem. Agricultural practices, construction, irrigation channels and environmental pressures arising from the road wetlands concluded that negatively affect. Addditionaly, aquatic insects are the most widely used organisms in freshwater where there is rarely human impact  and can provide reliable information on habitat and lake sustainability.

 

The objective of this study was to determine some order of macroinvertebrates spatial distribution and establish to chemichal parameters of the wetland. It was only once gone to research area in October. It was taken examples belong to aquatic Coleoptera and Hemiptera. After identificated which family and ordo, it was released to the lake in order not to ecologically imbalance of the lake ecosystem. It has been noticed that numbers of captured aquatic insect were not abundant because season was the autumn when collected.  For water analysis, water examples was transported with special water little container to East Anatolia High Technology Application and Research Center (DAYTAM, Ataturk University, Erzurum), then chemical parameters have been identificated at the center.

 

It has collected from the lake that ten individuals of aquatic coleoptera and hemiptera (Hydrophilidae one, Dystiscidae two, Dryopidae one and Corixidae one). All insect were dead under ice-layer and pale herbal. Water analysis have been applicated to some chemical analysis and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) instrument for obtain to data. Such as:  Cl (me/lt): 1,4; HCO3 (me/lt): 0,2; CO3(me/lt):1,2; Al (Cons.ppb): 0,382; Na (Cons.ppb): 264733,31; Mg (Cons.ppb): 59216,89; P (Cons.ppb): 10,479,  K (Cons.ppb): 3593,105; Ca (Cons.ppb): 2351,608; Cr (Cons.ppb): 0,099; Mn (Cons.ppb): 0,091; Fe (Cons.ppb): 1,968; Pb (Cons.ppb): 0,00; Ni (Cons.ppb): 0,702; Co (Cons. Ppd): 0,182; Cu (Cons.ppb): 1,063; Zn (Cons.ppb): < 0,00; Ga (Cons. Ppb): 0,043; As (Cons.ppb): 3,807; Se (Cons.ppb): 0,099; Ag (Cons.ppb): <0,000; Hg (Cons.ppb): <0,00 and Cd (Cons.ppb): < 0,00. Silver (Ag), Mercury (Hg), Zinc (Zn) and Cadmium (Cd) elements was not detected from the area. Morever physical data of the wetland have been detected with devices. Six different point of the region have been accumulated, then it has been calculated the aritmetic mean.  Such as;  Depth: 0,23±0,2 meter; Ph:7,42±,01, Electrical Conductivity (mS/cm): 0,23±0,1.

 

Same researchs will make new contributions to understand worth of the wetland and climate change on there in Turkey and in the world. Therefore, it is be expected that a strategy relating to the ecosystem diversity of the wetland area must be developed. Our research is a preliminary study, yet it needs to take more sampling and long-term chemical parameters to obtain more data on the islands in case the wetland may drought by affect of any climate change next years.
