Large-billed Reed Warbler
The large-billed reed warbler (''Acrocephalus orinus'') is an Old World warbler in the genus '' Acrocephalus''. The species has been dubbed as "the world's least known bird". It was known from a single specimen collected in India in 1867 and rediscovered in the wild in Thailand in 2006. The identity of the bird caught in Thailand was established by matching DNA sequences extracted from feathers; the bird was released. After the rediscovery in the wild a second specimen was discovered amid '' Acrocephalus dumetorum'' specimens in the collections of the Natural History Museum at Tring. A breeding area was found in Afghanistan in 2009 and studies in 2011 pointed to its breeding in Kazakhstan and Tajikistan. One bird was found in the Baikka Wetland in Srimangal, Bangladesh on 7 December 2011."Rare Bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sutlej Valley
The Sutlej or Satluj River () is the longest of the five rivers that flow through the historic crossroads region of Punjab in northern India and Pakistan. The Sutlej River is also known as ''Satadru''. It is the easternmost tributary of the Indus River. The Bhakra Dam is built around the river Sutlej to provide irrigation and other facilities to the states of Punjab, Rajasthan and Haryana. The waters of the Sutlej are allocated to India under the Indus Waters Treaty between India and Pakistan, and are mostly diverted to irrigation canals in India like the Sirhind Canal, Bhakra Main Line and the Rajasthan canal. The mean annual flow is 14 million acre feet (MAF) upstream of Ropar barrage, downstream of the Bhakra dam. It has several major hydroelectric points, including the 1,325 MW Bhakra Dam, the 1,000 MW Karcham Wangtoo Hydroelectric Plant, and the 1,500 MW Nathpa Jhakri Dam. The drainage basin in India includes the states and union territories of Himachal Pra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pamir Mountains
The Pamir Mountains are a mountain range between Central Asia and Pakistan. It is located at a junction with other notable mountains, namely the Tian Shan, Karakoram, Kunlun, Hindu Kush and the Himalaya mountain ranges. They are among the world's highest mountains. Much of the Pamir Mountains lie in the Gorno-Badakhshan Province of Tajikistan.

Bird Ringing
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Mahidol University
Mahidol University (Mahidol), an autonomous research institution in Thailand, had its origin in the establishment of Siriraj Hospital in 1888. Mahidol had an acceptance rate for Medicine of 0.4% as of the 2016 academic year. Becoming the University of Medical Science in 1943, it has been recognized as the country's fourth public university. The university was later renamed in 1969 by King Bhumibol Adulyadej after his father, Prince Mahidol of Songkhla, the "Father of Modern Medicine and Public Health of Thailand". The university originally focused on health sciences but expanded to other fields in recent decades. It hosted Thailand's first medical school, the Siriraj Medical School. Today, Mahidol offers a range of graduate (mostly international) and undergraduate programs from natural sciences to liberal arts with remote campuses in Kanchanaburi, Nakhon Sawan, and Amnat Charoen provinces. There are a total of 629 programs offered from 17 faculties, 6 colleges, 9 research insti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MtDNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from t ...
