A Comparison of Management Planning Principles of Wetland Ecosystem (The Delta of Bendimahi) and Mountain Ecosystem (Mountain of Ispiriz) in the Van Lake Basin/Turkey
(2013) Durmuş, A.; Alp, Ş.; Adizel, Ö.; Ünal, M.; Karabacak, O.; Demirci, E.Y.; Berber, Ş.
Van Lake Basin which is an important and different part of East Anatolia Region possesses important biological richness due to its geological, climatic, geographical and topographical varieties. In the region, Van Lake which is located between high mountains has led to the formation of a different climate which has resulted in different vegetation and formation of important wetlands. In the basin lies Ispiriz Mountain which is one of the important natural fields and Delta of Bendimahi which is an important part of the basin. Although the flora of Ispiriz Mountain has not been thoroughly studied, 35 of the plants which have been recorded from the area are classified as endemic, whilst 50 of them have been classified as rare plants. 15 of endemic plants have been collected from Ispriz Mountain and introduced to the world. 9 of these plants are endemic plants which have been recorded from a narrow area of Ispiriz Mountain. In the Delta of Bendimahi, there are 188 bird species. 68 of these birds are local, 80 of them migrant, 20 of them winter visitor, 15 of them transit migrant and 2 of them are determined to be coincidental. In this study, together with the socio-economic structure of Delta of Bendimahi which is wetland ecosystem and Mountain of Ispiriz which is mountain ecosystem, the existing relations and problems between natural resources have been determined. According to the gathered information, basic principles of management planning of both regions have been determined. In the presentation, the characteristics of both regions and similarities and differences between the two regions would be touched upon in terms of management of natural resources. It has been determined that the security and economical problems of the region have caused different difficulties in terms of studies which have aimed to determine natural resources in both ecosystems.
Hepatitis C Virus Positivity in Patients With Neoplastic Lymphoproliferative Disorders
(2004) Dilek, I.; Durmuş, A.; Akdeniz, H.; Topal, C.; Demir, C.; Topcu, N.
Several studies have suggested that infection with hepatitis C virus (HCV), that is a hepatotropic and neoplastic virus, has a role in the aetiology of neoplastic lymphoproliferative disorders. The results of some studies, however, failed to establish such an association in the aetiology of these disorders. In this study, hepatitis C virus (HCV) antibodies were searched in 116 patients with lymphoproliferative disorders (LPD) by a third-generation macro ELISA technique. Fifty two of the patients had been suffering from non-Hodgkin's lymphoma (NHL), 38 from Hodgkin's disease (HD), 15 from chronic lymphocytic leukaemia (CLL), 6 from Waldenstrψm macroglobulinaemia (WM) and 5 from multiple myeloma (MM). Voluntary blood donors were taken as a control group. The results showed that anti-HCV positivity in all cases was significantly higher than the control group (8.6% vs 0.8%). The rates of anti-HCV positivity were 33.3%, 5.7%, 7.8%, 6.6% and 20% respectively in WM, NHL, HD, CLL and MM cases. In conclusion, the findings of our study demonstrate the probable role of HCV infection in the development of neoplastic LPD in our region.
Using Poisson and Negative Binom Regression Models on Birds Population İn Dönemeç Delta
(Centenary University, 2018) Durmuş, A.; Yeşilova, A.; Çelik, E.; Kara, R.
The aim of this study to make a statistical estimate to bird populations in Dönemeç Delta using Poisson and negative binom regression models. According to Poisson regression model a deviance statistic greater than one (1) indicates that there is an over-dispersion in the bird’s population. The over-dispersion value in the Poisson regression was much greater than one (156.615). In contrast, the over-dispersion value in negative binom regression was close to one (1.277). Therefore, parameter estimations were interpreted according to negative binom regression. The effects of seasons, habitats and order (ordo) were found to be statistically significant on population density (p<0.05). Summer season when taken as a reference in all seasons only winter season was statistically significant (p<0.05). The population in sandy, farmland and stream edge habitats seen different according to other habitats (meadow, reeds and marshy) (p<0.05). When the Anseriformes ordo is taken as reference only two bird order were insignificant (p>0.05) according to 13 orders. © 2018, Centenary University. All rights reserved.
