As the weather in northern climates continues to change it becomes more important to the effects of the change on local species. The ability of theses northern species to adapted affects their survival s. Arctic foxes are one of the main predators of the terrestrial arctic ecosystem. Foxes main prey consists of small rodents, birds and their eggs in the summer and spring. Arctic foxes travel large distances searching for prey, averaging 29 km a day. (http://www.osti.gov/scitech/biblio/5927638). Many studies have been done on how food and resource abundance affects the foraging patterns, but not many studies have been done on how weather patterns and changing climate may be affecting the arctic foxes. One concern is that annual spring and summer …show more content…
Fox’s foraging technique is to only eat between 2-6 % of eggs they find immediately after discovering the nest and cache the rest of them for later consumption. (Samelius and Alisauskas, 2000). My project aims to look at whether variations in summer weather temperatures affects the foraging success of Arctic foxes. Since increasing temperatures should theoretically cause foxes to allocate less energy to keeping warm it is expected that there will be an increase in foraging time with an increase in temperature. This will result in more depredation events occurring in higher temperatures. In addition increasing temperature should cause an increase in food finding as noticed by increase in food …show more content…
If the results show temperature does affect the forging habit of arctic foxes this could have detrimental impacts on the balance of the Artic ecosystem. The changing temperature could have implications the longer term stability of the Arctic fox population. If rising temperatures cause an increase in the fox’s ability to find bountiful food supplies, it could cause a population burst resulting in overpopulation of the foxes. A very common example of this is of White tailed deer in North America. Deer became overabundant due to a surplus of food from agriculture, causing a large population growth resulting in over population. This overpopulation has caused damages to the ecosystem due to it increasing for more food resources. This over grazing resulted in a dramatic disappearance much of the local vegetation species as well as an increase in the mortality of the deer due to starvation from the resultant habitat loss. (https://books.google.ca/books?hl=en&lr=&id=gJE6JTNHd_UC&oi=fnd&pg=PA119&dq=overpopulation+due+to+prey+abundance&ots=4gP3mEDG1z&sig=21tjsofihVROZ_Txk3C8FoGHm2c#v=onepage&q=overpopulation%20due%20to%20prey%20abundance&f=false) . This resource instability may occur in Artic foxes due to overpopulation threatening the prey species of the Arctic Foxes. Arctic breeding shorebirds could be at risk due to the over population of Arctic Foxes. With more Arctic foxes there
Dad Weakness and Stents Christopher’s mommy and daddy have departed for every extended time. Christopher's father known as ED has been doing such a delightful job taking good care of his child ever since he was his youngster. When years came by, Christopher happened to lose confidence and trust in his daddy because daddy has been dishonest to Christopher. This book is so-called The Curious Incident of the Dog in the Night-time. This paper contains three literary elements.
The capture and control of a breathtaking and majestic creature such as a killer whale is a very tedious subject. Most of the general public would enjoy viewing a show where these giant mammals jump out of the water and perform stunning tricks for viewer satisfaction. But what the public doesn’t see, or realize is that these animals could be severely depressed and could be lacking mandatory stimulation through social bonds and other factors the ocean could give them rather than an oversized bath tub. The ethicalities of keeping such an intelligent animal like an orca in captivity has been under scrutiny for years in the marine biology community. Despite the controlled environments for orcas, these environments cause psychological and social problems to the animals and are worse than nature. There is a distinguishable trait in killer whales in captivity that doesn’t appear in whales in the wild, the dorsal fin of the animal in captivity almost always droops over to one side or the other, and less than one percent of all whales in the wild have been recorded in having this trait. This could be directly related to the depressing life an orca in captivity faces in a closed off world with limited stimulation from the animals incredibly in depth social attributes.
Not many people know about the arctic wolf, it is the snowy white version of a wolf. They have a really big appite when it comes to eating. They most only eat one meal a day and eat up to 20 pounds in that one meal. They are mostly carnivores; they mainly eat big animals like the caribou and the musk ox so they can feed themselves and the whole pack (Arctic/Antarctic: The Arctic Wolf). People eat up to three meals a day, but wolves can go up to days with out eating a single thing (Arctic/Antarctic: The Arctic Wolf). When wolves are hunting they have to be able to have a plan to catch their food. Wolves would get all the pack members that are hunting to surround the animal, and pounces on them. One bit to the neck and the animal would be dead. When they are eating they will eat everything, like the meat, shin, fur and bone (Arctic/Antarctic: The Arctic Wolf). Also Arctic wolves can live up to 20 years in captivity, while they can only live 7- 15 years in the wild (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most prettiest and unique types of wolf. When Arctic wolves are pups t...
Melting glaciers, dying animals, and invasive species, what is happening? The end of the world nope just a few effects of climate change on the Tundra. I’m Doctor Shannon Gallagher, a scientist working to stop climate change in the Tundra and around the world. There are may problems of climate change in the tundra but let me start telling you about a big one. This problem is that the glaciers are starting to melt faster which could flood the rivers they feed into and once the glaciers are gone then some rivers will dry up. Even though there are many more ways the tundra is effected let’s talk a little about this proposal before you learn more. With evidence from past and present this proposal will reduce the effects of climate change on the tundra by proposing funding be allocated to the use and encouragement of renewable resources and preserving the tundra ecosystem by stopping damage from coming to the habitat or food chain.
Polar bears don't just live on ice, they use the ice as an advantage to catch prey such as seals. Polar bears have adapted to living on ice and being able to withstand the cold weather. Now that the climate is changing at a fast pace, polar bears are losing their land because its melting, leaving them with no place to walk, sleep and taking away their way of hunting prey. (polar bears international, 2015) This is all happening so fast that there is no way polar bears will be able to adapt to the new environments, causing extinction. The arctic is warming twice as fast as the rest of the world is due to the build up of greenhouse gases in the atmosphere, making it a problem happening very rapidly. (Bagley, 2015) Temperatures in the Arctic region have risen 7 degrees Fahrenheit over the last half century. (Bagley, 2015) Population among polar bears has decreased up to 40% in some areas. (Bagley, 2015) With the climate getting warmer, ice is melting earlier every spring, and takes longer to freeze every winter which is disrupting the feeding and breeding cycles of many different arctic species. (Bagley, 2015) Polar bears have adapted ways to survive in the cold harsh arctic environment including having the ability to cool down their outer skin to keep their vital organs warm when they are submerged in cold water. Though this may help the delay of hypothermia as they have to swim greater distances from ice shelf to ice shelf, that doesn't mean polar bears can swim forever. (Bagley, 2015) One bear that a scientist studied swam 500 miles over nine days, but lost 22% of her body weight, and lost her cub.(Bagley, 2015) Many different scientists have been studying the behaviour of the polar bear to see if it could adapt in any way to survive. Eight U.S scientists made a hypothesis consisting that polar bears could lower their metabolic rates enough to survive as food
grizzly bears prefered habitat is deserted rivers, wild mountains, and thick and dense forest. Grizzly bears are majestic symbols of the wild. Bears live in and use a variety of habitat types, playing important roles in each one. This makes them an “umbrella species,” meaning that when we protect them and their habitat we also protect many species. Grizzly bears can also help ecosystems by distributing seeds and nutrients through their scat, and occasionally regulating ungulate populations.

The Arctic region is home to a variety of valuable animals and plants, including polar bear, seal, and so on. The ecosystem of the Arctic region is fragile because these animals are evolved to live in extreme conditions. With the climate change, many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of polar bears. Polar bears mainly feed on seals that indwell icy land. The melting ice reduces the number of seals and food intake of polar bears. In addition, polar bears are used to living in ice caves. The rising temperature causes the collapse of ice caves, which can kill baby bears. The climate change is negatively affecting the biodiversity in the region and will definitely harm the ecosystem
Whales are notable for being mammals which are fully adapted to oceanic life. These are three groups of Whales in their phylogenetic tree; Archaeocetes, Mysticeti and Odontoceti. The first group are known from their fossils and are seen to be a transitionary form as they retained a number of features associated with land mammals e.g. hind limbs with feet and limbs. The two other groups diverged around the start of the Oligocene; when the ice caps started to grow in the poles of the earth. It has been suggested that this may be due to the rise of seasonal planktonic production which could have led to specialisation (Houben, 2013); this ties in nicely with other summarisations which link the diversions of Whales in this time period. Mysticeti and Odontoceti differ on two counts; Mysticeti possess baleen making them filter feeders of plankton, in comparison Odontoceti possess a single set of teeth and have the ability to echolocate.
Whales are some of the ocean’s most fascinating amphibious beings. They possess highly acquired communication skills and are believed to have an intelligence level equal to, and in some species, surpass that of the human brain. The biological, anthropological, and marine educational communities have studied the whale in a way that sheds light onto the studies of evolution as well. Yet, there are industries that subject these animals to captivity, hindering the natural development of these animals. Of all the communities contributing to the protection and study of the whale, there is one tipping the scale towards exploiting it for profit: The entertainment industry.

One huge impact of global warming is the change in animals’ habitats. When the earth’s temperature is increasing, it creates the change of weather conditions in a certain area, which causes some kinds of animals in this area to live with many difficulties, or sometimes those kinds of animals are forced to move to new region when they cannot handle the difficulties. The arctic fox is an example for this situation. According to the article “How Does Global Warming Affect Wildlife,” arctic foxes prefer to live in the cooler environment while their habitat is getting warmer and warmer due to global warming, so arctic foxes have to leave their own home to seek a more suitable area (National W...
Stray animals are dangerous reason being is children or elderly people can be bit while walking or playing around at parks. I live in Mercedes and at one point when I was walking from stars to the high school, and stray dog for no reason started growing at me and my instinct was to run until I got the a building. This can happen to anyone, they can be attacked trying to touch a stray or just simply walking by, or even worse a child can catch a disease. Also owners with their pets are also getting attacked by stray animals because they strays tend to be over protective of their territory, or they just want to fight with the pet of the owner.
