A Biological Assessment of Exterior Reliefs of Akdamar Cathedral in Van/Turkey: Relief of Birds
(Editura Universitaria Craiova, 2019) Adizel, Ö.; Azizoğlu, E.; Yildiz, M.Z.
Historical Akdamar Cathedral is located on an island on Lake Van. The cathedral was built eleven centuries ago. The building has numerous exterior reliefs that encircle the Cathedral and are composed of four levels. They include historical, religious, and cultural compositions along with animal figures. Alongside the human relief sculptures on the building, the bird and mammal figures are very important in terms of reflecting the biological richness of the region. For this study, detailed photographs of the bird reliefs on the exterior walls of the Cathedral have been taken. The description of bird species on the reliefs are compared with the figures of the present-day bird species. Therefore, the similarity between the bird fauna of the region in the past and its current condition and the biological diversity of the bird species at that time are identified. Thus, it is revealed that nineteen species of bird living in the region at that time were engraved and immortalized. © 2019 Editura Universitaria Craiova.
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.
Examination of Helminth Parasites in the Fecal Samples of Magpies (Pica Pica), Jackdaws (Corvus Monedula), and Rooks (Corvus Frugilegus) in the Vicinities of Van Province/Turkey
(ABADER (Adıyaman Bilimsel Arastırmalar Dernegi), 2020) Yilmaz, A.B.; Azizoğlu, E.; Adizel, Ö.
The present study was designed to examine helminths in the gastrointestinal tract of corvid species including Pica pica, Corvus frugilegus, and Corvus monedula. A total of 43 fecal samples were collected from Pica pica, 42 samples from Corvus frugilegus, and 42 samples from Corvus monedula species. Feces were analyzed using sedimentation and flotation methods. Echinostoma spp. (2.32%), Capillaria spp. (6.97%), Syngamus spp. (2.32%), and Raillietina spp. (6.97%) were detected in Pica pica, Raillietina spp. (2.5%) and Capillaria spp. (10.0%) were detected in Corvus monedula, and only Capillaria spp. (9.52%) were detected in Corvus frugilegus. To our knowledge, this is the first study in Turkey identifying these helminth species in the fecal samples of these bird species. © 2020, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi).
