River Otters Case Study

Improved Essays
In the Health and Natural Science Building’s classroom, 147, Dr. Erin Barding elaborated about the recovery and management of a reintroduced river otter population. River otters, or Lontra Canadensis, are stocky mustelid and semi-aquatic. They appear in rivers, streams, lakes, and ponds. They have few natural predators and hold high value for their fur. In other words, otter’s fur are really dense and luxurious and can sell for $100-$200. Despite being awkward on land, otters are jet like in water.
They inhabited most major drainages but by the 1900s they became extirpated in the United States. This happened as a result of loss of habitat, unregulated trapping, agricultural and industrial improvements, as well as, mining. Not counting the fact that otters were causing problems to humans. For example, fish hatcheries and farm ponds were being wiped out by otters. Subsequently, fishermen started to get mad because there were no bass left; therefore, they began targeting the otters by trapping them.

Erin’s objectives were assess the population status of river otters, describe a statewide analysis of winter food habits for otters, describe age-specific reproductive parameters and produce a range of population estimates for otters, and provide management recommendations for river otters in Kentucky. Due to the low number of otters, she explained how lots of states have been reintroducing otters such as Missouri, Louisiana, and Kentucky. The otter reintroduction in Missouri was the number one carnivore reproduction reinstitution. Dr. Erin’s conclusions found that her data indicated a successful reintroduction because otters occupied all of the major watersheds, otters were not eating all of the small and large mouth bass, females go through delayed implantation, and the population growth of otters was

    This rapid population decline was due to an imbalance in the ecosystem. The island fox is the largest mammal native to the islands thus at the top of the food chain but it did not know how to protect itself when a new predator came to the northern islands. Bald eagles also lived on the northern islands and on Santa Catalina Island. But with the introduction of DDT used in WWII the chemical made the eggs of the eagle brittle and the eggs would break as parents would try to incubate them. Thus the bald eagle population decreased.…

    The purpose of this paper is to summarize the methods used by the Pew Charitable Trusts and the Western Association of Fish and Wildlife Agencies to release their findings on sage-grouse populations (Peterson, 2015 pg. 12). We will also be looking at their studies used and whether the decision of greater sage-grouse no longer being in need of the Endangered Species Act protection is the right decision. Ken Rait director of the U.S. public lands program at The Pew Charitable Trusts says “More than half of all sagebrush lands have been lost, resulting in a 95 percent reduction in greater sage-grouse population” (The Pew Charitable Trusts, 2015). Considering that sagebrush is habitat for over 100 species; Pew feels like the Bureau of Land Managements…

    1) After looking at the graphs in Figures 3 and 4, it is obvious that killer whales are the cause behind the deaths of a large amount of sea otters. Despite the data for Figure 3 showing all sea otter the researchers encountered, while the data for Figure 4 showing sea otters with radio tags, both figures still show a drastic decrease in sea otter population with the only main difference between Kulak Bay and Clam Lagoon being the ease of access that killer whales have to the areas. The researchers looked at 2 different sets of data because they wanted to show the general decline in the population in figure 3 and then show a more specific set of otters to show that the general decline was not because of human error. By having figure 4 focus on…

    Once seen throughout the southeastern United States, fewer than 100 Florida panthers are estimated to live in south Florida today. The current range is less than five percent of their original range across Florida, Georgia, Alabama, Mississippi, Louisiana, Arkansas, and parts of Tennessee and South Carolina. Today, the main threats are habitat loss, fragmentation, and degradation (National Park Service, n.d.). We need to recognize the signs and figure out how the stop the extinctions of today’s ecosystem. To get an idea of the shape and characteristics of a mature Florida panther, picture a large cat that has no spots and consists of mainly one color.…

    Introduction The reintroduction of the Mexican Gray wolf into the southwestern United States has been a subject of large controversy in the past few decades. They first became protected by the Endangered Species Act of 1976; this species that had numbers in the thousands only a few decades earlier had become completely extinct in the United States (Southwest Wildlife). In 1960 the population dropped to seven, and yet there were still no efforts to implement their recovery as a species for 16 more years. Currently the goal of the United States Fish and Wildlife Service is to expand the population in the wild to at least one hundred (Bergman).…

    One of the most renowned rewilding projects which has demonstrated the effects rewilding has on a whole ecosystem, was the reintroduction of grey wolves (Canis lupus) into Yellowstone National Park in the North West of the United States. The wolves were reintroduced to the park in 1995-1996 and have subsequently recolonised the whole park and some of the surrounding area known as the greater Yellowstone ecosystem (GYE) (Smith et al., 2003). The reintroduction of the wolves has had a great effect on the ecosystem of Yellowstone; the wolves have greatly reduced the numbers of ungulates, especially Elk which have been found to support the wolf packs almost entirely (Smith et al., 2003). The wolves have also had an effect on many of the other organisms…

    As Canadians manipulate natural habitats for farmland development and urbanization, the consideration for wildlife management of species including the Blanding’s Turtle becomes increasingly important. Recognized as an umbrella species, the Blanding’s Turtle may be a representative animal for its habitat and therefore monitoring its health may assist in selecting appropriate conservation strategies. Recognizing the decline in the size of many Blanding’s Turtle populations, several studies have investigated the behaviour and life-history of this species to better understand the factors threatening its existence. In a study monitoring the movement patterns of freshwater turtles, Gibbons (1986) noted that excursions by females for suitable nesting…

    Blanding's Turtles

    There are many plausible reasons for the discrepancy in the observed heterozygosity of Blanding’s turtles in the Kingston area. A few possible theories may explain these such as habitat loss due to the urbanization of Area 2, human impact, and nest predation. The Hardy-Weinberg principle states that the allele and genotype frequencies of a population will remain constant as long as population remains large. Thus, a change in the population may change the allele and genotype frequencies which may change the observed heterozygosity. Due to the amount of human interaction, the bottleneck effect, which occurs when the size of a population is reduced due to a natural disaster or human actions, may be occurring to cause the generic variance.…

    Orcas In Captivity

    Introduction Ever since 1961, humans have been removing orcas out of their natural habitats to go to places such as Sea World, where they are forced to perform tricks for people who pay to watch (Blackfish). Unlike orcas in the wild, captive orcas have been known to live shorter lives and go through traumatic experiences. Also, orca captivity has had negative effects on not only the orcas taken captive, but their families too. Due to the negative changes orcas experience from the wild to captivity, orcas should be retained in the wild, shouldn’t be separated from their families, and also should not be held in captivity to perform tricks for visitors.…
