Desert Saxaul

Photo: Black Saxaul (Haloxylon ammodendron)
Saxaul is found over a huge area (approx. 450,000 sq. km) of semi-arid and arid ecosystems within Central Asia. These so called cold winter deserts range through Uzbekistan, Turkmenistan, Kazakhstan and into Xinjiang, northwest China & Mongolia. Saxual is ranges in size from 2-8 m tall (in rare cases up to 10-12 m tall). It has a brown trunk 4-10 cm (up to 25cm) in diameter. Its wood is heavy and coarse and the bark is spongy and water-soaked. The branches of the young trees are vivid green (new growth) and hanging and turn brown, grey, or white as the tree matures. Branches formed in the current year are green whereas older branches are brown, or grey to white, the leaves of the plant are reduced to very small cusp-like scales, so that it appears nearly leafless. The inflorescences consist of short lateral shoots borne on stems of the previous year and flowers are bisexual or male, very small, als being longer or shorter than the bracteoles. The leaves are reduced to very small, pointed scales so that the plant appears nearly leafless. The flowers are small and yellow.  Flowers appear from March to April. In its fruit, the perianth segments develop, spreading pale brown or white wings diameter of about 8 mm (the seeds about 1.5 mm). Fruits appearing from October to November. Saxaul burns well and in some places it is the only kind of fuel wood that can be utilised for heating and cooking. It is also an important source of water in the arid regions in which it grows. Its thick bark acts as a water storage organ and drinking water can be obtained by pressing quantities of bark. Its wood is also durable and heavy and is used for building shelters.

A large number of birds including the Saxaul sparrow (Passer ammodendri) live in the ecosystem. They are at 14–16 cm long and weight 25–32 grams making them among the larger sparrow species.  A bird of the deserts, it favours areas with shrubs like the saxaul located near rivers and oases. Though it has lost parts of its range due to the expansion of agriculture, to date it is not seriously threatened by human activities.

Dark Star Cave - One of the Deepest Cave Systems in Asia

Is Asia's Deepest Cave System Underneath Uzbekistan? GO TO CAVE

Very little is known about the karst and caves in southern Uzbekistan, where some of the deepest caves in Asia have been discovered. In particular, the limestone plateau of the Baisun-tau mountain range has a tremendous potential for exploration.

This region is also important for palaeoclimate studies, as it is situated in the transition zone between the Westerlies and the Indian Summer Monsoon. Up until 15 years ago the  Festival’naya–Ledopadnaya cave system, was the main focus of cavers’ attention. Then, in 2011 the great potential of Dark Star Cave was revealed, after extensive new discoveries were made. Both the length and depth of Dark Star have been increased almost two-fold every year. So far, six entrances and 9,537m of surveyed passages have been discovered to a depth of −858m, and Dark Star has now become the focus of exploration for expeditions to the area.

Dinosaurs of Uzbekistan - Timurlengia euotica


A new species of tyrannosaur which has been discovered in the Kyzyl Kum desert of Uzbekistan.  From just a handful of fossilised bones and a well preserved brain case, palaeontologist’s have been able to build a picture of the dinosaur named Timurlengia euotica from fossils that have been found. The remains have been dated as being 90 to 92 million years old from the Cretaceous period.

This early tyrannosaur was a close cousin of the Tyrannosaurus rex and its discovery may hold the key to explaining how its infamous big cousins went on to become such fearsome predators and reach such massive sizes. It would have weighed between 170 to 270 kilograms, would have been about the size of a horse, covered in a mixture of skin and feathers. It was a nimble pursuit hunter and would have chased down its prey before making short work of them with its slender razor sharp teeth. It probably preyed on the various large plant-eaters, especially early duck-billed dinosaurs, which shared its world.

Paleontologists believe that Timurlengia euotica marks an evolutionary turning point for the tyrannosaurs, where the keen senses and brainpower of these top hunters were developed and refined.  Analysis of their brain casing showed it had already developed inner ear structures which would have enabled it to hear lower frequencies, a big advantage for predators when it came to hearing prey and rivals.  It also shows that the advanced brain and senses of the colossal later Cretaceous apex predator T. rex were were already present by the Late Jurassic, more than 90 million years ago. 

However, the sinuses of Timurlengia were seen to be much simpler than their later cousin - whose heightened sense of smell would have helped it to find prey - hinting that the tyrannosaurs had not yet finished evolving all of the master hunter's attributes. As these are on a separate branch of the tyrannosaur family tree, it would also indicate that the these attributes developed in a common ancestor even further back, before splitting off.

Plans for Tigers to once again inhabit Central Asia.

The Caspian tiger, Panthera tirgris virgata  which at 140 kilograms were among the largest cats to have ever lived.roamed Central Asia, from the Caspian Sea to north-west China, before reclamation of lands in the 19th century and hunting led to a significant decrease in availability of prey - wild boar and deer - that the tigers fed on.  It's not clear exactly when the Caspian tiger died out. Some reports suggest it was last seen in the 1960 in the Caspian literal of NW Iran, while others date its extinction to the 1970s the last reported sighting being in Kegeli in Karakalpakstan.

Ever since Caspian tigers disappeared, biologists and conservationists have tried to come up with a strategy to bring tigers back to Central Asia.  A recent study published in the Journal Biological Conservation has suggested that the Tiger could be effectively resurrected by reintroducing the genetically similar subspecies the Amu tigers from the Russian far east back into Central Asia. Between 2010 and 2012, scientists conducted a series of tests showing that the Caspian and Amur tigers were almost identical in their genetic structure.

Studies on the Siberian (Amur) variant found in found in the Sikhote Alin mountain region of the Primorye Province in the Russian Far East revealed that the two subspecies have diverged from a common ancestor relatively recently. Genetic mapping showing that the common ancestor of both subspecies colonised Central Asia via the same path as the Silk Road from eastern China about 10,000 years ago, at the end of the last ice age. Some stayed in Central Asia and became the Caspian tiger, whereas the rest of the population moved up to the Russian Far East and evolved into the Siberian tiger. They found that despite some very small physiological differences, the Caspian and Siberian tigers are essentially the same on a genetic level. Thus, the extant population in Russia is thought to be a perfect way to “breed back” the Caspian tiger to Central Asia by introducing Amur tigers into suitable habitats.

The likely first location identified as a habitable area on the south bank of Balkhash lake and the Ili river estuary in Kazakhstan. The reintroduction project has already had approval from regional wildlife authorities and national government agencies. As a part of the project, it is planned to create a national park, revive riparian woodlands, and increase the diversity of flora and fauna in general. In particular the types of mammalian prey that the tigers normally hunt, such as deer and wild pigs. In addition they will need to carefully monitor and conserve the water supply. These measures are predicted to take at least 15 years. The project then plans to introduce into the park up to 100 tigers, they expect that the population to grow and stabilise at around 200 tigers by mid century.

The World's Oldest Chess Pieces "Afrosiab Set"



Photo of the famous pieces found at
Afrasiab (near modern-day Samarkand)

Although there is scholarly disagreement about where chess originated - Central Asia, India, the Persian empire, and China are all contenders - it is certain that the game spread along the Great Silk Road. Indeed, the earliest, recognisable chess pieces, dated to about 760 AD were excavated at Afrosiabs north of present-day Samarkand in 1977 by a team led by Archaeologist Prof. Yuri Buryakov's from the Uzbek SSR Academy of Archaeology. (NB:
A coin, dated 761 was found with the chess pieces)

This find a sensational at the time included seven chess pieces. They were heavily worn, but clearly identifiable as two foot soldiers with shields and short swords (= our pawns); a war elephant with chain armour and a rider in full battle-dress (= our bishop); a visier (= our queen) with two horses with two mounted riders with sword and shield (= knights); and the Shah, on a three-horse chariot, holding a mace his symbol of power (= our king). The rukh (rook) also features a three-horse chariot with two men, one driving, and the other armed with sword and shield.
 
The set has five out of the six types of pieces, and are completely convincing as a chess set, being made at the end of the Sassanid Empire just before the Arabic conquest they are representational unlike later Arabic sets which used abstract shapes, in accordance with Islamic religious teaching.
 
Some other older statuettes which were also found in Uzbekistan are occasionally named as the worlds oldest chess pieces. They are figurines of an elephant and a zebu bull excavated in 1972 at Dalverzin-Tepe an ancient citadel of the Kushan empire located in Southern Uzbekistan, and stem from the 2nd century. The Elephant is about 2.4 cm high and the Bull is about 1.8 cm high. Some historians believe that they could also be toys or amulets which is quite possible. Also, it has been noticed that there is no Bull in the chess. Most chess historians feel as such that they are probably not Chess pieces, but probably belonged to a forerunner of Chess. They are kept in Tashkent.
