The advantages of Isolation
Arctic wolves really are a rare case of a lupine to whom urbanization and deforestation aren't a threat. Due to their remote, isolated habitats [url=http://www.cheapnbamavericksjerseys.com/]Wholesale Dallas Mavericks Jerseys[/url] , they have been comparatively undisturbed by man. They are at home roaming the grand icy landscape and inhabit a few of the very most inhospitable environments on Earth. Therefore it is fairly improbable that they encounter predators, although they are occasionally killed and eat by polar bears. He lives a life free from the threat of hunting and scarcely strikes humans.
Ready-Made Dwellings
For most of the year, the arctic wolf habitat is covered in thick ice. Unlike their cousins, timber wolves and the grey wolves who live further south in warmer climates [url=http://www.cheapnbamavericksjerseys.com/]Cheap Dallas Mavericks Jerseys[/url] , the arctic wolves cannot dig through the frozen earth to create lairs. For this reason, they shelter among trees and in caves and outcrops.
Food's current presence
The Arctic is a barren and vast continent. Prey animals' current presence discovers where the arctic wolf makes his dwelling. When there is no plant life caribou, musk oxen and arctic hares might survive, the arctic wolf will not be present. Many arctic wolf populations dwell near the ocean [url=http://www.cheapnbamavericksjerseys.com/]Wholesale Mavericks Jerseys[/url] , where they feed on seabirds and seals. Because food is not as plentiful in the Arctic, litters are generally smaller (two to three pups) than those of home wolves that are more southerly (five) although some female arctic wolves do have larger litters.
Dealing with all the Cold
The temperature in the Arctic regularly drops under -30 degrees Fahrenheit, and arctic wolves rely on their extremely thick coats for heat since they can not construct dens. They have muzzles that are shorter, stouter bodies [url=http://www.cheapnbamavericksjerseys.com/]Cheap Mavericks Jerseys[/url] , shorter legs and smaller ears than other wolves, which enables them to better keep their body heat. 2009 celebrates both the bicentenary of Darwin?s birth and the 150th anniversary of his seminal work ?Origin of the Species?, with this in mind why not take a holiday to the Galapagos and visit the islands that first inspired him.
Charles Darwin first came across the Galapagos Islands in 1835, when returning home from an educational visit to South America where he had been collecting animals and fossils and studying the geology of the region. He spent five weeks studying the flora and the fauna of the region [url=http://www.cheapnbamavericksjerseys.com/...e-juan-barea-jersey/]Jose Juan Barea Jersey[/url] , but it was the giant tortoises that particularly attracted his attention. Darwin later wrote that: ?anyone with half an eye could immediately tell which of the Galapagos Islands the tortoises were from by their distinguishing characteristics?.
The tortoises can still be seen on a holiday to the Galapagos and have been known to reach up to four feet in length. However, the huge island tortoises are not the only animals which you are likely to spot on your Galapagos island holiday. The island?s eco systems means that they are home to a wealth of unique animals from hammerhead sharks to manta rays and sea lions.
Indeed it was the uniqueness of the animals that first got Darwin thinking along the lines of evolution. On surveying a couple of green iguanas he was amazed to discover that whilst they resembled the common South American green iguana, both had adapted to suit the ecological climate of the Galapagos Islands. One of the green iguanas had adapted to feed on the spiky leaved cactus plants of the region, whilst another had a flattened tail which enabled it to swim in the sea [url=http://www.cheapnbamavericksjerseys.com/steve-nash-jersey/]Steve Nash Jersey[/url] , along with a blunt snout which allowed it to scrape the algae from rocks. His study also commented on the thirteen differing species of finches on the island, whose beaks had been adapted to suit the different climes.
Whilst the brightly coloured finches spotted by Darwin are still abundant on the island, the most unusual birds which you will spot on your Galapagos tour are the Frigate birds. During mating season, the male birds inflate their brightly coloured red pouch in order to attract a female mate. Another resident of the Galapagos Islands also on the lookout for a female mate is Lonesome George. George can be seen at the Charles Darwin Research Station and is believed to be the last remaining tortoise on Pinta Island.
All of the islands were formed from volcanoes and evidence of this can be seen at Isabela Island. Isabela has five active volcanoes and is also home to the second largest volcanic crater in the world [url=http://www.cheapnbamavericksjerseys.com/jason-kidd-jersey/]Jason Kidd Jersey[/url] , Sierra Nevada. On your Galapagos Island holiday walking around Isabella gives you a feel for how the islands were created and some of the questions that plagued a god fearing Darwin at the time. Charles Darwin believed that as the islands were volcanic they must have been recently formed, meaning that animals that dwelt there had to have originally come from someplace else. This conflicted with his Christian views in accordance to Genesis that God had created all plants and animals, and that they had not changed significantly since that time.
When on your Galapagos Island holiday you will have the amazing opportunity of coming face to face with the incredible animals and natural landscapes which helped shape Darwin?s new theory and the way that people now think today.
