Research Paper On North American River Otter

Lane Spotted Elk is a Montana State University student from the tribe Northern Cheyenne/Crow. Lane has a strong social side of the health triangle. He worked at the Boys and Girls club which made a big impact in his life. OPI Honor Yourself Poster Series states that “‘I was at the point...I needed something bigger than myself.” So lane turned to the Boys and Girls club…” This quote shows that Lane had the ability to ask for help which is part of the health triangles social side. He actually took advice from other people, in his case the Boys and Girls club. “Lane...was nominated as a representative… and was named as the representative from Montana…” (OPI Honor Yourself Poster Series) This evidence makes it clear that Lane's Social side is strong,

The Arctic wolf is a sub-species of the grey wolf and lives in the Arctic regions of North America and Greenland. Arctic Wolves also live in, Montebello, Quebec, Canada. The arctic wolf if a mammal.

The study conducted by Weisle, Nagaswami, and Peterson is displayed about river otters and how they are different in structure from other marine mammals. River otters must depend on their thick layer of hair for survival. River otters are semi-aquatic mammals, which are considered to have denser fur than any other mammals. It’s thick, sleek coat, which keeps it dry and warm, is made up of two types of hair. The longer outer hairs are water repellent as known as guard hairs, and the other is underhair. The guard hairs could provide some protection for the more delicate underhairs. The three authors of this article, “River otter hair structure facilitates interlocking to impede penetration of water and allow,” addresses a question upon why the

Arctic fox is small animal that can reach 26 inches in length and 6.5 to 17 pounds of weight. Bushy tail is usually 13.7 inches long.

The Big Sioux River runs through the eastern part of South Dakota and supplies water to some of the state’s most populated areas, including Sioux Falls and the college town of Brookings. It was recently rated the 13th dirtiest river in the country and supplies water to thousands of people! What has made this water so dirty and what is being done about it?

Both the passage and the lecture discuss the decline of some sea otters’ population in Alaska coast. On the one hand, the passage argues that this decline is due to environmental pollution. On the other hand, the lecture opposes by stating that predation is most likely the reason for the phenomena.

The grizzly bear was first found in Big Madly Creek on April 29, 1805. The grizzly bear is found in Southern and Northwestern states. You could also find them in Idaho, Montana and Wyoming. Sometime they wander into Washington and, Colorado. The grizzly bears usually can be found in the mountains and open areas near rivers and streams. The grizzly bears fur is brown and tan. The ends of the hair had white tips. The grizzly bear had claws and walks on all fours.

It has came to mind that the Big Sioux River located in the Eastern Part of South Dakota is a very polluted river. It is so polluted that its the 13th highest polluted water source in the United States. Therefore the people around this river, this is a very important to the people around because this is there main water source. People may ask why is this river so polluted and its because of the toxic waste from us humans. Every time you go to the bathroom all this waste ends up going into the river and even when you take a shower all the chemicals that go in your hair or for your body from the soap end up going into the river.

A River Otters classification begins with the Domain Eukaryote. The Kingdom Animalia, which means they breathe oxygen and they are able to reproduce. The Phylum Chordata, which means they have a hollow dorsal nerve cord, a notochord, Pharyngeal

There are 16 different breeds of otters. Sea otter, Eurasian otter, Lutra, Lontra, oriental small clawed otter, Giant otter, smooth-coated otter, African clawless otter, Northern River otter, Asian small clawed otter, Congo clawless otter, marine otter, neotropical otter, South American otter, spotted-necked otter, and hairy nosed otter. This animal is pretty much always near water, they are usually found near both freshwater and coastal marine, such as, lakes, rivers, inland wetlands, coastal shorelines, marshes, and estuaries. Otters can be found in North America & other places as well. Otters eat fish, crabs, sea urchins, abalones, clams, mussels, and snails. They are preyed on by bobcats, coyotes, mountain lions, wolves, black bears, and

The article claims that the population of the sea otter has declined because of pollution, pradators and, uneven pattern of ocean currents. On the other hand, the professor does not believe factors of why otters dissappered and opposes each reason.

A chestnut colored, furry blur races past you as you are paddling your boat in a North American lake. You wonder what it could be! It is most likely a North American River Otter. In this essay, I will be informing you about this interesting member of the weasel family.

Sexually mature females can mate year around and are often either pregnant or caring for young throughout their lifetime, and this creates ongoing energy demands that can be energetically exhausting (Chinn et al. 2016). Sea otter mating behavior is aggressive and can further inflict physiological and traumatic stress to females, thereby reducing their foraging efficiency. Other factors such as infections, disease, bio-toxin ingestion and anthropogenic disturbance can also decrease fitness among adult females and increase their vulnerability during reproduction (Chinn et al. 2016). As nearshore inhabitants, southern sea otters often live in close proximity to areas of high human population density in California. These nearshore waterways can be busy with recreational and commercial boating activity that can disturb sea otter populations. Increased disturbance may cause increased stress to the species. Sea otters are of great interest to people who wish to view them, and this is sometimes done up-close by boat or paddle craft. If this activity changes sea otter behavior in any way, it not only violates the Marine Mammal Protection Act, it can also have a negative impact on the species, especially adult females with pups. Additionally, a familiar list of human impacts, such as climate change, overharvest of marine resources, municipal runoff, and habitat degradation likely reduce fitness of marine mammals directly and indirectly. Sea otters can be indicators of the overall health of the nearshore ecosystem (Kreuder et al. 2003). The slow growth rate of the southern sea otter population may be an expression of nearshore ecosystem degradation in California resulting from the fur trade and explosion of human population in

As referred to in “Zoologists and Wildlife biologists Ocupational” the median salary for a wildlife biologist is about $59,680 per year which is $28.69 hourly. The lowest ten percent earned less than $39,180, and the highest ten percent earned more than $97,390. According to “Salary:Wildlife Biologist” the average annual pay for the Johnstown area is about $42,061. Depending on where you work you will get paid a different amount. Overall Pennsylvania has an annual salary of $60,000 and and hourly pay of $28.85. West Virginia has an annual salary of $47,300 and $22.74 hourly. Connecticut has an annual salary of $91,240 and a hourly pay of $43.87("Zoologists And Wildlife Biologists :: Salaries"). You don't immediately get paid that amount of money. Depending on how long you have

The River otter is also known as northern river otter or common otter. Most female otter reproduce annually and in order to breed successfully they need certain things such as: habitat, prey and density-dependent factors. The habitat of a river otter can vary they can be found in places such as: streams, rivers, lakes and marshes. These areas tend to have more vegetation and prey. For this animal quality water and year-round access to water is very high on the hierarchy of needs. Otters can stay submerged in water for four consecutive minutes. River otters feed primarily on fish. The otters don’t have a preference when it comes to fish, they will seek
