Şanlıurfa ilinde tarımsal ve doğal alanlarda nematod biyoçeşitliliği.
Özet
Summary
Nematode biodiversity in agricultural and natural habitats of Sanliurfa, Turkey.
The study was conducted to examine the biodiversity of terrestrial nematodes in agricultural and non-agricultural areas of Sanliurfa, Turkey. Study area defined with the semi-arid features consisting irrigated and dry cultures, has been divided into 5 sub-regions regarding the geographic and ecological boundaries. Samples were taken twice a year, one in the mid-spring and second in the mid-fall for 3 years, in 2003-2005.
Nematode fauna has been represented by 26 species, 28 genus, and 4 families which all belonged to 8 orders. The proportions of plant parasitic and free-living nematodes were 39 % and 61%, respectively. Plant parasitic nematodes were represented by 26 species and 6 genera belonged to 2 orders (Tylenchida and Dorylaimida); bacterivores were represented by 4 families and 10 genus belonged to 4 orders (Rhabditida, Cephalobida, Diplogaterida and Monhysterida); fungivores were represented by 3 genus belonged to 2 orders (Aphelenchida and Tylenchida); predators were represented by 2 genus belonged to 2 orders (Mononchida and Aphelenchida) and the omnivores represented by 7 genus belonged to 1 order (Dorylaimida). Diversity of nematode communities either in the plant parasitic fauna or the free-living fauna have displayed differences in the sub-regions of the study area. The main reason may be due to the past history of the agricultural practices employed in each of the sub-regions.
