The Great Bustard Otis tarda is a globally threatened species with populations inhabiting the steppe zones of Turkey. In recent decades, its populations in Turkey have suffered severe declines in range and size. Although the remaining populations are in urgent need of protection, there has been no national-scale study on the species since 2009, and huge information gaps remain concerning its range, abundance, and movements in the country. Here, we combined data from five years of fieldwork together with all available sight and literature records to present up-To-date estimates of distribution and population size in Turkey, to better understand its movement patterns, to reveal its recent and historical population changes, and to assess its national extinction risk and threats. We find that the species' breeding population has shrunk by 20-29% over the last five years, and there are only 559-780 breeding Great Bustards in Turkey distributed in two discrete subpopulations. Comparison with historical records shows that the species' range has shrunk by at least 60% since the beginning of the 20th century. We suggest possible migratory routes within and through Turkey and that Turkey might have a higher regional importance for the species than previously thought. Illegal hunting, agricultural intensification, shift to irrigated crops, overgrazing, collision with powerlines, and disturbance are the most severe threats to the species in Turkey. Our national Red List assessment yields an Endangered categorisation. Further studies are needed to understand the metapopulation structure and movements of the species and to conserve its remaining populations in Turkey.

Current status of Great Bustard Otis tarda in Turkey: population size, distribution, movements, and threats

Breeding biology, population size and spatial distribution of a common nightingale (Luscinia megarhynchos Brehm, 1831) Population at Yalıncak (Ankara)
Özbahar, İlker; Bilgin, Cemal Can; Department of Biology (2005)
Many bird populations are known to show strong territoriality as well as high site fidelity during breeding. The Common Nightingale (Luscinia megarhynchos) is one of many such migratory species that annually occupies the same favourable habitat. Especially dominant males prefer to breed in the same area every year, and high fidelity probably assures high breeding success. This study aims to investigate breeding biology, population size and spatial distribution of nightingales at a small area in Yalıncak wit...
Systematics of West African Miniopterus with the description of a new species
Monadjem, Ara; Shapiro, Julie T.; Richards, Leigh R.; Karabulut, Hatice; Crawley, Wing; Nielsen, Ida Broman; Hansen, Anders; Bohmann, Kristine; Mourier, Tobias (2019-12-01)
The phylogenetic relationships and species limits within the chiropteran family Miniopteridae are poorly known in mainland Africa. Recent systematic studies in Madagascar have shown that this is a species-rich family, yet only eight species are currently recognized or hypothesized for continental Africa. Based on partial cytochrome b sequences and morphometric analysis, we describe a new species of Miniopterus that is endemic to a restricted, montane region of Liberia and Guinea. Furthermore, the taxonomic ...
Phylogeography of Turkish Honeybees (Apis mellifera L.) Based on mtDNA Sequences
Çelikgil, Atila; Kükrer, Mert; Bilgin, Cemal Can (null; 2019-07-09)
There are 26 recognized subspecies of honeybees throughout the world and 5 of them are distributed in Turkey. Due to the migratory beekeepers and queen trade practices in addition to other anthropogenic factors, population structure of these 5 subspecies are under threat and require further research followed by immediate establishment of conservation strategies. In this study, we aimed to determine the phylogeography and biodiversity of Turkish Honeybees. In order to assess genetic variability and populatio...
Genetic Diversity Pattern of Salix alba Populations in a Fragmented River Ecosystem in Eastern Mediterranean
Özdemir Değirmenci, Funda; Acar, Pelin; Kaya, Zeki (null; 2016-01-13)
The genus Salix L. is represented with more than 500 species in the world and 28 of species are found naturally in Turkey. The species of the genus have been widely used for bioenergy and phytoremediation. Salix alba like many other willow species is with great renewable energy potentiali and important component of an healthy riparian ecosystem as an indicator species in major river ecosystems in Turkey. With this study, it was aimed to provide information for efficient conservation, management and util...
