Arctic hares have unusual habits that help protect them from cold environment and predators. Sometimes they huddle in large groups, hundreds of them, keeping their bodies close together for warmth and it’s harder to attack if together. If a hungry wolf or arctic fox happens to surprise the group, the hares scatter into different directions and confuse their predators with their speed and numbers so they have a greater chance of surviving/getting away. At rest, arctic hares appear smaller than they actually are. They sit on their legs and flatten their ears to conserve their body heat. Unlike hares that live in warmer regions the Arctic Hare has relatively short ears; which have developed that way to limit its body's exposure to the cold.
Cactus
Instead of leaves, most cacti have spines or scales (which are modified leaves). These spines and scales do not lose water through evaporation (unlike regular leaves, which lose a lot of water). The spines protect the cactus from predators (animals that would like to eat the cactus to obtain food and/or water).
The general characteristics of minks is that they are mammals just like humans, which means that we both are born with hair, mammary glands for the females and different characteristics in our anatomy to those of birds and reptiles. Their scientific name is Mustela Vison. The mink has very long trunk, short legs and very large neck. The tail is thick and the feet are slightly webbed enabling them to swim better. In all the mink measures about 12-15 inches long and weight 1 ½ to 3 pounds. The fur is very dark almost black, on the chin the fur is white with a little white fur on its throat.
They survive in some of the coldest places on earth, they have a number of anatomical, behavioural and physiological adaptations that allow them to do this successfully. Arctic wolves live for around 7 to 10 years in the wild.
Abiotic factors of the arctic tundra are strong winds, little precipitation. Also very short summer days, instead there are very long and cold winters. There is poor soil and a permafrost which is a layer of permanently frozen subsoil. The biotic factors are that plants and mosses have to adapt to the long and cold winters, since the sun does not come up during winter. Also the wildlife animal that live there are Snowy owls, reindeer, white foxes, lemmings, arctic hares, wolverines, caribou, migrating birds, mosquitoes, black flies, and the chief predator the Polar
“200 years ago, there was around 16 million greater sage grouse; Today there may be fewer than 200,000” (Dantzker and Swartwout). The Greater Sage Grouse (Centrocercus urophasianus) is a magnificent bird that only lives in the Sagebrush-steppe habitat. This habitat is seen in the western part of the United States and also some area of North and South America. From the study above, it should be obvious that the greater sage grouse were considered endangered by Fish and Wildlife Organizations. However, on September 30th, 2015, the U.S. Fish and Wildlife Organization removed the sage grouse from the endangered “candidates” list, and stated that they would enforce plans to help the conservation of these birds. People should be aware that this is
sea otters are from the kingdom animalia. Sea otters are stouter and have large rib cages, smaller tails and muzzle than other species of otters. Yet sea otters posses the fine, dense fur coats characteristic of the Mustelidae. Their forefeet are small and dexterous with retractile claws and the flipper like hind feet are broad and webbed. Sea otters once was abundant along most coastal North pacific ocean. That was before fur traders hunted them for their thick ice, luxurious pelts. By the year 1900, sea otters were nearly extinct . Protected since 1911, alaska sea otters have made a comeback. There lifespan is 10-15 years. Great white sharks are the primary predator of sea otters and occasionally eaten by coyote so the predators that the
The color of the fur varies depending on the location of the its habitat. Generally, koalas living in the South have fur that is darker than those living in the North. The fur protects the koalas helps maintain its temperature from cold and hot weathers. It also acts as a raincoat and repels water. In cold weathers, the fur acts as a great insulator and protects koalas from losing too much energy (calories) fighting the cold. Furthermore, in hot weathers, the fur protects koalas from losing water in their body. Regarding a koala’s posture and habitat, it has a denser fur on its rump that is consisted with tougher connective tissues. The thick fur acts as a cushion for its bottom when sitting on a tree. The fur of koalas keep their body temperature stable and provides a cushion for its usual posture sitting on a
The habitat of the Arctic wolf is a very harsh place. The temperature must be below zero degrees. There are tundra, rolling hills, glacier valleys, ice fields, shallow lakes, and green flatlands (Arctic/Antarctic: The Arctic Wolf). These snowy white creators don’t have that many places to live. Arctic wolves used to be everywhere in North America, but sadly now they are reduced to Canada, Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin, and Wyoming (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most dangerous types of wolves; people need to find a way to save them and their habitat before they disappear forever.
The climate of the tundra is characterized by harsh winters. The average temperature in the tundra area is about –27 degrees. But what is even worse are the long night. At nights the lowest temperture recorded was –67.36 degrees. There are even times in the year when the sun doesn’t come up for days. In the tundra we have little snow and even less rainfall. The rainfall is about a quarter inch in a yearly rainfall. Even though the tundra’s winters are long a harsh there summers are the shortest season of all. Do to the terrible weather and climate in the tundra their animals and plant life is very limited.
Kenneth Coates, author of Furs Along the Yukon: HC-Native Trade in the Yukon River Basin examines and explores the Fur Trade of the Yukon River Basin before the Klondike Gold rush in pursuit to analyze the early economic development of Yukon. Coates furthermore attempts to question the native-European exchange in one of the last regions of initial contact between aboriginal residents and Europeans in North America. It was believed that the miners and the Herschel Island whalers impacted the fur trade, varying the customary demands of the natives and transformed the native economy and HBC, and Americans, whom didn’t have significant impact of the structure and content of the fur trade. The Natives recognized their own necessity to trade and
Elizabeth Bishop's "The Moose" is a narrative poem of 168 lines. Its twenty-eight six-line stanzas are not rigidly structured. Lines vary in length from four to eight syllables, but those of five or six syllables predominate. The pattern of stresses is lax enough almost to blur the distinction between verse and prose; the rhythm is that of a low-keyed speaking voice hovering over the descriptive details. The eyewitness account is meticulous and restrained.
It allows them to live long because they have two different genes in them and it also allows them to survive anywhere in the world because their fur is mixed. They have brown fur that allows them to be on land for a long amount of time and they have white fur which allows them to live in the snow and let them stay in freezing water for a long amount of time.
The winter will last 8 to 10 months followed by the short and much less cold summer. During the summer some lower areas of the Tundra will defrost at which point most of the flora and fauna will start to creep out of hiding. The few summer months are used by many animals such as the polar bear, to mate and to prepare for the once again oncoming winter. During the winter months, most everything remains frozen. Many of the animals migrate south for the winter whereas some stay behind or even group together for ritual group suicide (lemmings).
Compared to the size of a teacup, the eastern gray squirrel is a small animal, with body length ranging from 25 to 30 centimeters tail lengths ranging from 22 to 25 centimeters, and weighing 400 to 600 grams. Contradictory to their name, their fur color is not gray but a combination of black, white, and brown colors. This fur coat that creates a gray illusion helps the squirrel blend into their environment.
Gopher tortoise are ectotherms that can mostly be found in the southeastern parts of the United States because of the sunnier weather in that area. They are known for digging burrows underground that can be 12 meters long and 3 meters deep. Many species live with the gopher tortoise in the burrows that they make for protection against fire, predators and also for warmth during the cold nights and to stay cool in the hot days. Species that lives with the gopher tortoise includes: rabbits, burrowing owls, mouse, frogs and many different types of small insects. Since the gopher tortoise are considered as threatened species, it has become very important to protect them as the burrows that they dig helps to increase the diversity of species in the area. There are also many causes that has led to them becoming threatened such as their low reproduction rate, loss of habitat due to urbanization and the predators that prey on their eggs and young hatchlings. Because the gopher tortoise can only lay up to 8 eggs in one year, protecting the eggs from predators like coyotes or raccoons is crucial for their future population. Also, protecting the young hatchlings is just as important because they are still
In this slideshow I will talk about their habitat what they eat and their predators and how the life cycle would stop like if there is a miss card for a deck of cards.
