Malleefowl Taxonomy

The environment in which organisms live plays a large part in natural selection as well. Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer ["Natural Selection and Speciation - Biology."]. One example of evolution through the process of natural selection is that of the Viceroy butterfly. The Viceroy butterflies were facing extinction a little more than 100 years ago due to their inability to protect themselves or hide from their predators; mainly birds.

A Study Case of Amazonian Calf Interactions Introduction The Amazonian manatee is a very well known and loved species of manatee. Out of all of the Manatee species the Amazonian manatee is the smallest that utilizes only fresh water habitats. It has a fairly limited habitat that falls in the Amazonian Basin 's rives and lakes. They play an important role as a ecosystem primary producer. Unfortunately the species is considered Vulnerable on the Red List of Threatened species of the International Union for Conservation of Nature due to human interaction.

Evolution was helping the tweezys out here, at any given moment evolution could have chose to kill them off and focus on a different species. Instead evolution had this bird develop a successful beak compared to other birds beaks. After the disaster the tweezys thrived then another round of natural selection and still came in seconds after the spoon mutated. Overall evolution made tweezys’ beaks different than others to see if they survived, and when they did, evolution would keep the beak type cycling around the

Researchers of a study performed on wild and captive orangutans write, “…Factors such as improper hygienic situations, improper diet, diseases, obesity, injuries from exhibits, poor adaption to a climate, spread of infections, inbreeding, and social stress might actually increase mortality in captivity”, (De Vries 680). The study described how the modern improvements for zoo animals have only recently matched the average survival rate of wild species. Although this statement is true to some degree, it can also be argued that studies on mental characteristic are not one hundred percent accurate. Another study on assessing the mental health of captive and wild chimpanzees describes the multitude of uncontrollable variables when testing hypothesizes. The testing methods are not catered specifically to nonhuman primates and to other non-vocal species.

This exposure and education motivate people to protect the animals and provide entertainment. Zoos save endangered species by bringing them into a safe environment, where they are protected from poachers, habitat loss, starvation, and predators. “The Arabian Oryx was hunted to extinction in the wild. However, from just a handful of animals in captivity the species was brought back from the brink thanks the conservation efforts of Phoenix Zoo and others. Through this incredible work, there are now over 1,000 of these magnificent animals back in the wild and thousands more looked after by zoos worldwide.”(CSA, page 1) “In 1975 the wild population of the Puerto Rican parrot was down to just 13 birds.

Deeply affected by human encroachment into its territory, when the species was declared federally endangered in 1967, only about 12 individuals remained in the wild (Threats to Florida Panthers). Currently there are around 180 individuals in the wild, and the US Fish and Wildlife Commission’s Florida panther plan defines a successful panther population worthy of delisting the species as endangered. Its requirements for delisting are as follows: “Three viable, self-sustaining populations of at least 240 individuals (adults and subadults) each have been established and subsequently maintained for a minimum of twelve years. Sufficient habitat quality, quantity, and spatial configuration to support these populations is retained / protected or secured for the long-term. (fwc panther

The Hawaiian monk seal population cannot continue to survive and grow if less juvenile female pups are reaching reproductive age and not surviving, this has caused the current decrease in Hawaiian monk seal populations to continue to decrease and to decrease more rapidly (Norris et al, 2011). To do this, more projects such as Head Start need to be planned and implemented to help save the shrinking population. For example, an additional research and rehabilitation center on either the French Frigate Shoal or Green Island could be used and would be extremely beneficial.

According to the Environmental Defense fund, “In the Gulf of Mexico, red snapper populations are three times what they were in 2007 when we helped reform that fishery” so if we use their methods many other countries might be able to re populate their fish. 2. Alternatives to overfishing and how the normal population can help control it. A. There are many alternatives to overfishing that will help control the population.

A population and habitat viability analysis was carried out to develop a conservation action plan to improve the status of wild dogs in Southern Africa (Mills, et al. 1998). A priority outcome of this workshop was the recommendation to establish a second viable population of wild dogs in South Africa that would complement the unmanaged populations. This population would be managed in a facilitated meta-population manner. This action plan advocates for the identification of suitable protected areas to establish sub-populations by developing criteria for selecting prospective sites (Mills, et al.

In a article it was stated, “In addition, zoological parks and aquariums have played a role in helping to preserve species that have been driven close to extinction due to habitat loss and hunting” (Point). Taking an endangered animal out of its habitat and putting it in a place where it cannot be harmed will help out that species for a while. The Zoos main part it plays is protection for that endangered species, but what is questioned is the fact that is it actually being protected or is the Zoo causing more harm. In the article, “Zoos and Circuses: Overview”, it is correctly stated,” The birth of the environmental movement in the 1960s and '70s led to the establishment of laws protecting species threatened by extinction, including the 1973 Endangered Species Act (ESA) in the United States. These laws also established guidelines for establishing the conservation status of species and provided federal oversight over the keeping of rare or endangered animals.

The objectives of the recovery plan is to remove the ferret from the threatened/endangered list and in order to achieve this the plan will begin working on downlisting the species before finally removal. The downlisting objectives include the establishment of at least “1,500 breeding adults, in 10 or more populations” across at least 6 of the 12 historical range states and maintaining the population at least three years before downlisting the species (USFWS, 2013). Additionally, maintaining an approximate 247,000 acres of prairie dog habitat and conserving and managing a minimum of 280 breeding adults across three facilities to insure a healthy stock (USFWS, 2013). In order for complete delisting of the species the goal numbers are double of the wild breeding ferret at 3000 and the total acreage 494,000 (USFWS,

The Greater Akialoa is extinct on all of the islands. Forest clearance on the islands and diseases from insects like mosquitos are the main causes of them dying out. To summarize , the Greater

Scientists are working hard to find a cure and the Save the Tasmanian Devil Program is working to save them from extinction, as it is said maybe in 30 years time, these Tasmanian Devils will become extinct. Description of zoo enclosure - photo or

The Forest Service and Bureau of Land Management (BLM) have a legal responsibility under the Wild Free Roaming Horses and Burros Act to ensure that protected wild horses on federal lands do not end up being rounded up or slaughtered. There are several ways to get involved in helping save the Salt River wild horses and other wild horses in the US. You could sign the petitions or contact advocacy groups who organize events, legally intervene to halt roundups, and work with the government agencies to find solutions. The Salt River Wild Horse Management Group is an AZ based non-profit Organization (501c3), set up to protect and preserve the Salt River Wild Horses. The goal of the Salt River Wild Horse Management Group is to monitor, watch over and establish a scientific perspective on herd dynamics, migrating patterns and birth and death rates.

Including gradually expanding the reserve to facilitate population growth. Reintroduce natural predators such as the woma pythons to control overpopulation and help manage a more balanced ecosystem. Installing one-way gates from the reserve to allow natural dispersal of bilbies into the untracked land outside of the reserve. Also trying to establish a population of wild bilbies introduced directly outside of the reserve to determine if the bilbies would survive in the
