Rodent and Beaver

5. Conduct research on one mammal that lives on the tundra and prepare a short essay on your mammal.

I disagree with my review because of the following reasons. When I tested I was given the animal the otter, Otters have a personality to be excitable energetic and the cheerleading type, this is not me. However, I was also given the animal the beaver and I also disagree with this because beavers are said to be organized perfectionist kind of people and this is far from who I am. Beavers are very detail-oriented, orderly and enjoy thoroughness I am more of the go with the flow type person and am far from organized. I would agree more with the idea of me being a golden retriever, golden retrievers are very team oriented, easy going and quit calm type of people. And I feel like these are some of the traits that fit me best. I tend to be very

The Point Arena mountain beaver (Aplodontia rufa nigra) is a federally listed endangered subspecies that is restricted to the small area of Point Arena, in coastal Mendocino County, California (Zielinski, et al., 2013). (See Figure 1). The Point Arena mountain beaver is a dark brown, medium-sized burrowing rodent with small ears and eyes, and long whiskers and claws (National Park Service (NPS), n.d.). The subspecies is semi-fossorial, spending most of its five to six year lifespan in underground burrows (United States Fish & Wildlife Service (USFWS), 2011). The burrows are typically found on moist and steep north-facing slopes or in well-drained gullies; each burrow contains separate chambers for food storage, nesting, and excrement (NPS,

-Growth in beaver populations meant more dams which had multiple beneficial effects on streams and rivers. Dams slow seasonal water runoff and help to maintain a healthy water supply. The pools created by dams also created good habitats for fish. More abundance of willows made great songbird habitat.

A wide variety of animals live in bottomland hardwoods. There are many waterfowl and other birds, such as wood ducks and screech owls. Other animals, like deer, squirrels, and bats, also live in or nearby the foliage of these wetlands. These animals are mostly intrusive, since they can choose to live in other areas if they wish.

The European mink has distinguished itself from its close relatives due to its outstanding attributes and differences, for example, the European mink posses a slightly smaller body alongside a more massive skull than other related species, such as ferrets and other minks. Additionally, the European mink's anatomy comprises of a relative small yet compacted body, alongside a ambiguous weight and mass on the upper part of the mammal regarding sexual dimorphism. In the other hand, the American Mink withholds a larger body than the European Milk due to it's longer tail; moreover, the longer body provides numerous advantages, such as reducing water resistance while swimming and allow them to hunt its prey. However, both minks collectively contain similar attributes to each other and other related species, such as the ferrets and weasels, as they all share a similar structure and fur

Sloths are known for being one of the slowest mammals and for their longs claws, which can help tell each sloth apart. The two and three toed sloths may seem the same to most people, and while they have some things that are alike, they are more different from each other than people think from the number of toes, to their appearance, their skeleton structure, and what they eat.

Badgers Diet Badgers are carnivorous animals eating mostly pocket gophers, prairie dogs, ground squirrels, pika, woodrats and kangaroo rats. They usually do this by digging the prey out of the ground in their dens or chasing them down.

The Woodchuck is not a very large animal by any means, but in its family its among the largest ranging from ranging from 16-26 inches in length (Bio-expedition, 2015). The Woodchuck can weigh anywhere from as little as four pounds to as much as nine pounds (Bio-expedition, 2015). They are a stocky animal and have a very short tail. They have very powerful front appendages that they use to dig elaborate burrows. They also have a two layer coat the help them help protect them from the environment. On the outside the Woodchuck has brown coat the helps repel water and on the inside they have a very dense fur for warmth.

Most significantly, this upset the whole balance of nature. With no more beavers to build dams and the preexisting ones decaying, water systems were greatly damaged.

For example, their concept indicates that prey species will alter their foraging habits to the features of the terrain in order to avoid areas with a high risk of predation. Predation risk in a changing environment is also focused on by the authors. There are many environmental variables that may influence the degree of predation risk such as weather, wildfires, and other conditions that influence ungulates’ access to vegetation. Finally, the authors focus on ecosystem responses to trophic cascades—primarily on riparian functions and on beaver and bird populations. They also inform us that wolves may represent an indirect control on beaver populations as well as cause ungulates to avoid some riparian areas—therefore reducing herbivory on wooden browse species.

The Brown-throated Three-toed Sloth is approximately the size of a house cat, ranging from 45-60cm. Like all sloths it has long limbs and a small head for the size of its body. Sloths’ fur hangs ‘backwards’ compared to other mammals, lying from the stomach to their back. This enables the water to run off while it is in a tree. Sloths do not have visible toes but instead have long claws. In this species they have three claws on each foot, which enable them to hang from the branches of trees (2). The brown-throated Tree-toed Sloth can also be distinguished from other species by its brown fur and upturned mouth, giving the sloth a constant ‘smile’.

Sloths are slow-moving mammals that spend their lives hanging about in trees of Central and South America. They look different and are defined by how many digits they

River Otters are a species found on 5 out of 7 continents in the world. They have short legs that allow them to swim, walk, groom, and manipulate their pray effectively. Generally, they are various shades of brown, but they have a darker dorsal, and a lighter ventral. Their head, eyes, ears, nose, and teeth are beneficial for them when hunting prey, and when being hunted. River Otters have unique characteristics, features, and lifestyles that allow them to be not only adorable, but important to many ecosystems.

They reproduce rapidly, as generally it is the case with small prey animals. No matter how well they are cared for, they possess somewhat short life span. Generally they have short gestational periods and their quick sexual maturity makes effective rodent control decisive. The reproductive cycle and the number of these rodent’s offspring increases with sufficient water, food and harbourage.
