New species tree-dwelling porcupine discovered in critically threatened Brazilian habitat

April 11, 2013

Scientists in Brazil have described a new species of tree-dwelling porcupine in the country’s most endangered ecosystems. The description is published in last week’s issue of Zootaxa.

A team of researchers led by Antonio Rossano Mendes Pontes [2009 interview], a biologist at the Federal University of Pernambuco, found the porcupine in a small forest fragment in the state of Pernambuco. They christened the rodent Coendou speratus, a combination of its local name “coandu-mirim” and the Latin word “speratus” for “hope”.

The name choice is appropriate given the porcupine’s high risk of extinction. About 98 percent of its forest habitat has been destroyed, while its population is as fragmented as the forests it inhabits, making the species vulnerable in inbreeding, according to the researchers. The species is also actively hunted…

Greenland:Land of the Kalaallit

Greenland  is an autonomous country within the Kingdom of Denmark, located between the Arctic and Atlantic Oceans, in east of the Canadian Arctic Archipelago. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe specifically Norway and  Denmark for more than a millennium due to political and cultural reasons.

Greenland is, in terms of area, the world’s largest island,over 3/4 of which is covered by the only contemporary ice sheet outside of Antarctica. With a population of 56,370 (2013), it is the least densely populated country in the world.

Greenland is an ancient settlement and has been inhabited off and on for at least the last 4,500 to 5,000 years by Arctic peoples whose forebears migrated there from Canada. Norsemen settled on the uninhabited southern part of Greenland in the beginning of 10th century. Inuit peoples arrived here in the 13th century. The Norse colonies disappeared in the late 15th century. In the early 18th century, Scandinavia and Greenland came back into contact with each other, and Denmark established sovereignty over the island.

The last written records of the Norse Greenlanders are of a marriage in 1408 in the church of Hvalsey—today the best-preserved Nordic ruins in Greenland.

Having been ruled by Denmark-Norway for centuries, Greenland  became a Danish colony in 1814, and a part of the Kingdom of Denmark in 1953 under the Constitution of Denmark. In 1979, Denmark granted home rule to Greenland, and in 2008, Greenlanders voted to transfer more power from the Danish royal government to the local Greenlandic government. Under the new structure, in effect since 21 June 2009,the Danish government retains control of foreign affairs, national defence, the police force, and the justice system. It also retains control of monetary policy.

Some More  History

The  people migrated to Greenland across the Davis Strait from the American continent more than 4,000 years ago. The  links with Europe were established with the Norse settlements in 985 AD and lasted until the mid 15th century. The flourishing European whaling industry in the 16th century restored regular visits to Greenland, but a permanent link was not established until the settlement of the Danish-Norwegian priest Hans Egede in 1721. This formed the basis of Danish sovereignty for the next 258 years, where the establishment of the trade monopoly the Royal Greenland Trade Department, the KGH (Kongelige Grønlandske Handel), was particularly significant.

The Name

It was the early Scandinavian settlers who gave the country the name Greenland. In the Icelandic sagas, it is said that the Norwegian-born Icelander Erik the Red was exiled from Iceland for murder. Along with his extended family and his thralls, he set out in ships to find the land rumored to lie to the northwest. After finding it and settling there, he named it Grœnland (translated as “Greenland”), supposedly in the hope that the pleasant name would attract settlers.

The name of the country in Greenlandic (Kalaallisut) is Kalaallit Nunaat (“land of the Kalaallit”).The Kalaallit are the indigenous Greenlandic Inuit people who inhabit the country’s western region.

Economy

Until the Second World War, Greenland was a closed country with a very low standard of living. In 1906, sheep farming was introduced in the southern part of the country and commercial fishing started in 1908. During the Second World War, the German occupation of Denmark meant that all contact with Denmark was suspended and officials in Greenland and Washington made contact with the USA, which agreed to defend Greenland; in 1951-1952 an American military base was established at Thule. After the war, a popular movement arose in favour of modernisation of the country and the basis of the welfare system which today characterises Greenland was laid in the 1950s.

CLASSIFIED CRYSTALS – A QUICK SUMMARY

Igneous rocks are referred to as Primary Minerals,

Sedimentary rocks are Secondary Minerals,

Metamorphic rocks are Tertiary Minerals.

This crystal, found in a river in China, has an interesting history. It started life as a clear quartz cluster, but over time became submerged in river silts. Eventually the crystal was completely transformed as the sediments infiltrated the molecular lattice, and replaced the pure silicates with river sediments.

This Sediment Quartz, now has the texture of jasper, but has retained its quartz crystal appearance.

The diagram below represents the various transformations that rock will experience long after its igneous birth. On the clockwise turn rocks are undergoing changes related to environmental forces.  On the anti – clockwise turn rocks undergo changes brought about by heat and high pressures.   Metamorphic rocks can become sedimentary and vice-versa.  Eventually all rock returns to the magma below via subduction. At the same time new rocks…
