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...

Nine cases of carotid body tumor chemiodectomas in seven Patients are presented and diagnostic and therapeutic problems discussed Similar to other reports, many cases undergo operative exploration without correct preoper.ativ.e diagnosis or ability of the surgeon to handle such lesions. The most important factor for correct diagndsis is including carotid body in differential diagnosis of latera...
متن کاملCygnus A
We present ASCA gas temperature maps of the nearby merging galaxy clusters Cygnus A, A3667, and A2065. Cygnus A appears to have a particularly simple merger geometry that allows an estimate of the subcluster collision velocity from the observed temperature variations. We estimate it to be ∼ 2000 km s−1. Interestingly, this is similar to the free-fall velocity that the two Cygnus A subclusters s...
