There are eight species in the genus Phacellaria, six of which are distributed in tropical and subtropical mountain areas of South and Southwest China. The species belonging to this genus are obligate hemiparasites on plants in Loranthaceae and Dendrotrophe (Santalaceae).

We are all children at heart. When we want something, we want it now and are willing to trust in fate if it means that we can get it now. Many bird owners are like this. They want a bird, so they buy it. They don’t necessarily spend the time to research the source of the bird, and often there is little money left over to make sure that their purchase is healthy. Many people buy birds and know v...

Birds in pet trade are still a continuing issue beyond protection and conservation. Parakeets and allies are the majority among reported species. Identifying a species under forensic investigation is a challenge, as many cases involve trade of newly hatched chicks, juveniles and eggs where morphometric identification fails. Molecular identification using selective DNA markers, especially mitoge...

194 kiwi deaths reported in Northland between 1990 and June 1995 were caused primarily by dogs, indicating that the "Waitangi dog incident" of 1987 was not an isolated instance. Over the five and a half year period, dogs accounted for 135 (70%) of all reported kiwi deaths and 78% of all deaths for which the precise cause was established. The second greatest cause of death was vehicles (12; 6% o...

The study of cross-species pathogen transmission is essential to understanding the epizootiology and epidemiology of infectious diseases. Avian chlamydiosis is a zoonotic disease whose effects have been mainly investigated in humans, poultry and pet birds. It has been suggested that wild bird species play an important role as reservoirs for this disease. During a comparative health status surve...

تصویربرداری pet یکی از روشهای مقطع نگاری در پزشکی هسته ای می باشد. حساسیت و رزولوشن مکانی بیشتر و نیز قابلیت کمّی سازی بهتر، از مزایای تصویربرداری pet در مقایسه با spect می باشد. هر چند که سطح بالای نویز در این تصاویر صحت تشخیص را کاهش می دهد. بطور معمول، حذف/ کاهش نویز در پزشکی هسته ای بر پایه تبدیل فوریه تصاویر می باشد. این تبدیل، محتوای فرکانسی یک سیگنال/ تصویر را بدست می دهد اما در مورد مکان...
