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.
