Evaluating Genetic Diversity of Whooper Swan (Cygnus cygnus, Linnaeus, 1758) Colonies in Iran
Whooper swans have two old and new populations, the new population has reported since 2007. The current study aimed to investigate the genetic structure of this species and compare their gene pool, especially the new population. For this purpose, 110 samples from Iran and four European countries were analyzed, using six microsatelite loci. In addition to the samples of the emerging population i...
متن کاملA Comparative Analysis of Genetic Diversity and Structure of Whooper Swan (Cygnus cygnus): A New Considerable Established Population in Iran
New wintering populations of Whooper Swan have been recently reported from west Asia, a lack of information about the population and its origin. The understanding the genetic structure and connectivity are crucial for determining strategies of management for its conservation programs. The samples were collected from two populations in northern Iran, Finland, Sweden, and Iceland, where with larg...
متن کاملPopulation size and breeding success of the Icelandic Whooper Swan Cygnus cygnus: results of the 2015 international census
The seventh international census of Whooper Swans in Britain, Ireland, Iceland and the Isle of Man took place in January 2015, to update estimates of the size and midwinter distribution of the Icelandic Whooper Swan population. The 34,004 swans recorded represented a 16% increase in numbers compared to the previous census in 2010, a 155% increase on counts made in 1995, and was the highest cens...
متن کاملLead isotope ratio measurements as indicators for the source of lead poisoning in Mute swans (Cygnus olor) wintering in Puck Bay (northern Poland).
Lead (Pb) poisoning is most commonly linked amongst anthropogenically-caused deaths in waterfowl and this is often associated with hunting and fishing activities. However, the exact identification of the source may be difficult with commonly-used techniques. We have studied isotope ratios using Inductively-Coupled Plasma Mass Spectrometry (ICP-MS) to investigate the source of Pb in the blood of...
متن کاملMigration of Whooper Swans and Outbreaks of Highly Pathogenic Avian Influenza H5N1 Virus in Eastern Asia
Evaluating the potential involvement of wild avifauna in the emergence of highly pathogenic avian influenza H5N1 (hereafter H5N1) requires detailed analyses of temporal and spatial relationships between wild bird movements and disease emergence. The death of wild swans (Cygnus spp.) has been the first indicator of the presence of H5N1 in various Asian and European countries; however their role ...
