Living Some Macroinvertebrates and Chemical Some Data of Erzurum Wetland (Yakutiye, Erzurum, Turkey)

Summary<o:p></o:p>

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. <o:p></o:p>

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. <o:p></o:p>

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. <o:p></o:p>

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. <o:p></o:p>
