    A Bibliometric Analysis: What Do We Know About Metals(Loids) Accumulation in Wild Birds
    (Springer Heidelberg, 2021) Celik, Emrah; Durmus, Atilla; Adizel, Ozdemir; Nergiz Uyar, Humeyra
    Metals and metalloids pollution is an important worldwide problem due to the social and ecological effects and therefore has been the subject of many disciplines and the adverse impacts have been documented. In this study, content analysis and trends of studies focused on heavy metal accumulation in birds were presented. For this purpose, a bibliometric network analysis of the studies that use the concepts of "pollution," "heavy metal," and "birds" together in the abstract, keywords, and titles of the papers was carried out. The purpose of choosing this research method was summarizing the relation between birds and environmental pollution in an understandable manner to determine metals(loids) pollution, which become an important environmental problem. Bibliometric data consisting of approximately 971 papers were evaluated with VOSviewer program using the network analysis method to answer the research questions. The results revealed that birds act as bioindicators in the determination of environmental pollution and that the contaminant metals deposited in the various tissues of birds provide preliminary information about environmental pollution. The most of bird studies emphasized that the metal accumulation was mostly in the liver, kidneys, and feathers and the accumulation caused serious problems in most of the vital activities of the birds. The USA is in the leading country in birds-heavy metal studies followed by Spain, Canada, and China. In addition, the mercury (Hg) was the most extensively studied heavy metal in these studies.

    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.

    Feeding Ecology of Black-Crowned Night Heron (Nycticorax Nycticorax) in Van Lake Basin
    (Foundation Environmental Protection & Research-fepr, 2011) Durmus, Atilla; Adizel, Ozdemir
    In the present study, the feeding ecology of Black-crowned Night Heron (Nycticorax nycticorax) was investigated. The study was carried out in wetlands in the basin between 16th February 2006 and 4th October 2007. It was observed that The Night heron prefer the muddy and marshy places where freshwater joins to the lake for feeding. The morphometric measurement of chicks was done to determine the development related to the feeding. The measurement consisted of weight, tarsus, bill length, wing length, wing length, height and middle toe length. The Night heron feeds with animal foods. The vomiting samples of sixty (60) individuals and materials in nest were taken and seven (7) animal species belonging to five (5) classes were determined as feeding material of the Night heron (Chalcalburnus tarichi that a endemic fish species live in Van Lake, Rana sp., Bufo sp., Mus musculus, Microtus sp., Helix sp., Neuroptera's larvae). There is no plantal feeding material in feed range.

    Prevalence and Molecular Characterization of Moniezia Species in Ruminants Based on Its1-5.8s Rrna From Van Province, Turkey
    (Univ Agriculture, Fac veterinary Science, 2025) Yilmaz, Ali Bilgin; Azizoglu, Erkan; Adizel, Ozdemir; Goz, Yasar; Celik, Burcak Aslan; Celik, Ozgur Yasar; Uslu, Ugur
    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.

    (Polish Soc veterinary Sciences Editorial office, 2018) Yilmaz, Ali Bilgin; Kilinc, Ozlem Orunc; Adizel, Ozdemir; Bulum, Emre; Yuksek, Nazmi
    This study aims to identify the ticks living on reptiles of Small Nemrut Mountain as ectoparasites. Field work was carried out between May and November 2016. The mountain which attracts a lot of visitors is an extinct volcano. There are settlements close to the mountain. Furthermore, the area is the upland for the local fauna. 12 reptile species live on the mountain. In the scans on reptiles living in the area, the Hyalomma aegyptium type tick is identified on Testudo graeca (Common Tortoise) and Darevskia valentini (Valentin's Lizard) species. The infestation rate was found to be 66.66% on tortoises and 28.57% on lizards. In the resources, it was reported that Borellia turcica, Theileria spp, Borellia burgdorferi, Anaplasma phagocytophilum, which are microorganisms with high pathogenicity in humans and animals, are isolated from H. aegyptium collected from tortoises. In addition, it was reported in various studies that Hyalomma aegyptium is a reservoir host for Hemoliva mauritanica which is a blood parasite that has been identified to intensively cause diseases in tortoises.

    (Agricultural Research Communication Centre, 2018) Aslan, Logman; Adizel, Ozdemir; Sancak, Tunahan
    Today, the ecosystem is being rapidly destroyed due to habitat loss, animal hunting, road construction, raising of transmission lines, general pollution, and agricultural activities, in addition to many other factors, all of which directly and indirectly affect wildlife. By necessity, rehabilitation units are available for the care and treatment of wild birds and mammals in need of life support. This paper discusses data collected regarding the treatment and rehabilitation of wild mammals and birds brought to the Center for Wildlife Conservation and Rehabilitation at Van Yuzuncu Yyl University from 2009-2016. During the course of the present study, total 145 wild animals including 117 birds and 28 mammals. Out of the total treated, 96 wild birds and 21 wild mammals recovered, 12 birds and 4 mammals died without responding to treatments, whereas 9 birds and 3 mammals were euthanized. Additionally, of the 96 birds and 21 mammals that recovered, 15 birds and 6 mammals were determined to be unable to survive in their natural habitats, and were sent to zoo gardens or wildlife conservation and rehabilitation centers. The remaining 96 animals that fully recovered were released back into their natural habitats.
