Temperature Mediated Moose Survival

We looked first at the relationship between the wolf population and the moose population. From about 1960 to 1970, the wolf population remained fairly consistent at about 20 to 25 wolves. During this time, the moose population grew steadily from 500 to over 1200. The next 10 years saw a doubling of the wolf population to 50. This same 10 years saw a decrease of the moose population from over 1200 to over 800. Then in 1980 began a two year drastic decline in the moose population, which was brought down to 15. For the rest of the decade, the moose population remained quite low at numbers near 20. During the 1980s, the moose population doubled again from around 800 to

The purpose of this paper is to explore available research on the overpopulation of the Snow Goose on the North American continent. The snow goose has been rising in population since the middle of the century and has been escalating so much it is destroying their natural habitat. Wildlife managers have just recently begun to implement strategies to combat this problem. Mainly through the use of hunters the managers are trying to curb the population growth.

The introduction of the wolves caused the moose population to decrease. The moose population dropped to approximately 150 when the wolves are present.

Global temperature increases and associated increases in precipitation in northern Nova Scotia will likely have detrimental impacts on already threatened species. The Canadian Lynx population is decreasing quickly due to human hunting for its fur and its habitats being destroyed forcing them to continuously migrate north. They have evolved to thrive in snow cover and cold temperatures with their large snowshoe-like paws and thick fur, which gives them an advantage to capture prey compared to other predators such as coyotes or bobcats ("Threats To Lynx" 2012, Hoving et al. 2003). The lynx is a specialist predator focusing on the snowshoe hare as its primary source of food. The hare and the lynx have a very interconnected population cycle that lasts roughly 10 years (Yan et al. 2013). Hares experience large fluctuations in their population cycle based on a number of factors that influence the ecosystem. When hare populations are in decline, in periods where nature must regenerate, the lynx population is also shown to decrease, and vice versa with an approximate two year lag period for the lynx (("Lynx-Snowshoe Hare Cycle | Environment And Natural

Today one is lucky to see a deer in Washtenaw country, typically the most wild animal someone would come in contact with would be a squirrel in the daytime. That’s not the case for the little island in Lake Superior. Over 1500 moose call the island home. Nearly that many beaver do as well. At one point,

Environmental changes due to our climate warming is causing terrible effects on the Marten population in the northern reaches of Wisconsin. What climate change is doing to the habit in which the Marten is living in is changing the amount of snowfall the regions in which the Martens are living in are acquiring. Looking at figure 3 you can see that the total snowfall in the two regions where Martens were reintroduced showed significantly less snowfall accumulation in present day compared to the 1980’s. This is extremely important to note because this change in snowfall can deteriorate the critical zone called the subnivium. The subnivium is the seasonal microenvironment underneath the snow (Pauli et al., 2013). This is a small zone where plants and small mammals thrive during the winter. It should be stated that the subnivium insulates the ground creating a pocket of warmth that allows these organisms to survive the harsh Wisconsin winters. The way a subnivium is formed is based on snow duration, density and depth (Pauli et al., 2013). But this is where climate change comes into play. It is causing snowfall to decrease, the time snow is present is decreased and the density of the snow is lower (Pauli et al., 2013). Having these three factor decline is getting rid of the refuge of the subnivium and killing organisms that thrive there. One such organism is the American Marten. These mammals are small enough to crawl down tree trunks where the snow is melted to gain access to the subnivium. This is where the Marten hunts mice and other small mammals to its heart's content. But with the loss of the subnivium Martens can’t hunt in their little paradise. They will have to find other places to hunt and find prey to satisfy their caloric needs. This is where the Fisher has the advantage, since they are too large to access the subnivium. The Fisher

With their habitat being wiped away, their own food sources being toxic, to the very environment harboring chemicals; they are truly struggling to survive. Furthermore, hunting, although not a threat on its own, poses a great deal of risk to this species because of the threats outlined previously. If it were not for the disadvantageous situation the species currently face, it would likely not pose a threat at all. The aim of this paper is to provide an overview of the threats faced by polar bears in Canada such as global warming, bioaccumulation of mercury, biomagnification of polychlorinated biphenyls and hunting. Furthermore, hunting quotas placed on northern Indigenous populations will be analyzed as a conservation method that is helping to reduce further strain on the existing populations of this Canadian

When looking at the Thule Indian tribe that is based in Northern Artic such as Baffin Island and Greenland locations we can see that weather would indeed play a huge part in their daily lives. Researchers understand that climatic changes in these areas influence the ecological conditions in not just land but also the sea animals that were available to the Native Americans (Schledermann, 1976 P: 37). Due to the sea –ice condition we ended up see that even the migratory habits, food availability, breeding, and even denning habitats change. This is mainly because land animals are often more sensitive to changes in the biotopes (Schledermann, 1976 P: 37). It is believed by some researchers that weather would have been warmer 800-1200 A.D

There is a correlation, that in areas where caribou population has decreases (mainly due to logging), the wolverine population has also significantly reduced (slough). During the mid 1900’s, Canada enforced a large-scale wolf poisoning and trapping in hopes to reduce livestock depredation and remove ‘invasive species’ which negatively impacted the wolverine population in the process (slough). The development of mines, pipelines, housing and the roads leading to these areas created fragmented habitats and population isolation from wolverines have continually effected the range of wolverines (Jonhson). Despite the population decrease occurring since the development of human settlement, populations across Canada, but especially in the North remain healthy and far from becoming classified as ‘threatened’

The subsistence way of living in a small village can change over the years. The climate today is better for the moose to survive because there is less snow and it’s warmer. There is now more bears and wolves around this land because of the moose. The calves survival percentage is lower due to all of the moose's predators.

As I finished packing my suitcase the night before we left for Churchill the excitement started to settle in; the next morning we were leaving to hunt my first snow goose season. For anyone who doesn't know snow goose are now considered a bit of a nuisance out on the tundra, the once endangered species is now one of the most abundant waterfowl on the continent. Snow geese can eat their way across the tundra very quickly, destroying their habitat as they migrate through not only for themselves, but for other animals that also depend on the vegetation. I have hunted waterfowl before, harvesting the odd snow that was mixed in with the flock of Canadas but this was the first time I had traveled to target the species. That night I could hardly sleep I was so anxious.

The Alces alces benefits from forest fires because Canadian moose tend to live in areas recovering from forest fires. This is due to the growing vegetation with high nutritional content (McGarry, 2015). Forest fires also produces favorable habitats for moose, which will be common as the temperature continues to rise, causing an increase in the moose population as they enter, and leave recovering forests (McGarry, 2015). The recovering forests includes forests that does not usually

2) What was the background for the study? That is, what previous knowledge did the author describe as a foundation for the study in the “review of related literature?”

(47-48) This warming of the arctic also affects humans around the world not just the indigenous people and animals. David Rind says “these increases in temperature around the arctic will most certainly impact our weather here in the United States if we do not have those seemingly unneeded outbreaks of arctic cold then we will not receive as much winter precipitation which will make it hard for states like Kansas to produce their winter goods”. (qtd in Johansen 286)

Different types of animals are adapted to the environment. It explains why people need to use furnaces, heated blankets, and other devices to survive the freezing cold winter, animals live through the four seasons – especially winter – even if the temperature is several degrees below zero.
