Biological Assessment on External Reliefs of the Historical Akdamar Church: Reliefs of Mammals
(inst Zoology, Bas, 2018) Adizel, Ozdemir; Toyran, Kubilay; Azizoglu, Erkan
The Akdamar Church on the Akdamar Island, Lake Van, located within the borders of Bitlis and Van Provinces, is a historical artifact dating back to the XI-th Century. While historical reliefs on the external walls of the church point out religious and cultural values, they also include various biological figures. Reliefs of plants, birds and mammals, virtually as fossils, give significant clues about biological diversity from the region from those periods. In this study, detailed photographs of reliefs representing mammals on the walls of the church were compared with currently known species and species on the reliefs were identified. Thus, similarities between mammal fauna of the region in the past and nowadays were revealed. In this study, a total of 17 mammal species (including three domestic animals) were identified.
Chewing Louse Species (Phthiraptera: Amblycera, Ischnocera) on Roadkill Wild Birds in Van Province: Five New Species in Turkey
(Agricultural Research Communication Centre, 2022) Yilmaz, Ali Bilgin; Azizoglu, Erkan; Adizel, Ozdemir
Background: The present study was conducted to identify the lice species in birds that were struck and injured or killed by motor vehicles along the highway surrounding Lake Van, which is located between Van and Bitlis provinces in Turkey. Methods: The bird feathers were inspected using a macroscope. The isolated lice were placed in tubes containing 70% alcohol and were made translucent by 10% KOH. They were then glued using Canadian balsam and identified under light microscopy. Result: Of the 102 birds collected, 40 (40.8%) birds were infested with at least one louse species. In infested birds, 14 individual lice from 11 species were identified. Of these, Coloceras damicome (Nitzsch, 1866), Columbicola claviformis (Denny, 1842), Ricinus serratus (Uchida, 1926), Philopterus coarctatus (Scopoli, 1763), Upupicola upupae (Schrank, 1803) were identified in birds for the first time in Turkey.
Prevalence and Molecular Characterization of Moniezia Species in Ruminants Based on Its1-5.8s Rrna From Van Province, Turkey

This study aimed to calculate the occurence of Moniezia species in cattle, sheep, and goats in Van province and to identify these species using morphological and molecular methods (ITS1-5.8S rRNA gene region analysis). Additionally, the study aimed to identify the genetic differences between Moniezia expansa and Moniezia benedeni. During the summer of 2022, intestinal contents were collected from 150 ruminants (50 cattle, 50 sheep, and 50 goats) slaughtered in slaughterhouses in Van province. The parasites were examined using Aceto-Carmine staining, and species identification was based on interproglottidal glands. Examination of the intestinal contents revealed that 2 out of 50 cattle (4%), 14 out of 50 sheep (28%), and 9 out of 50 goats (18%) were infected with Moniezia. Morphological and molecular analyses showed that the cattle samples were identified as Moniezia benedeni, goats samples as Moniezia expansa and those from sheep as 11 Moniezia expansa and 3 Moniezia benedeni. Following DNA extraction, the ITS1-5.8S rRNA gene region was amplified using PCR and subjected to sequence analysis. The relationship between species was examined by phylogenetic tree. This study confirms the prevalence of Moniezia spp. in Van/T & uuml;rkiye by using the ITS1-5.8S rRNA gene.
