1. Give 3 examples of endemic and 3 examples of an invasive species.
Endemic species invasive species
Blue fin tuna snakehead fish
Asian elephant stink bugs
Sperm whale Zebra mussels

2. Pick one species (endemic or invasive) and discuss its role in the environment.
I choose an endemic species the Asian elephant. The elephants importance is that they assist with logging forests, carry heavy material, and assist as transportation. They have the ability to walk in areas where machines are unable to go, their vital role in an ecosystem is they modify the habitat that affects all other plants and animals. They provide water for other animals by digging water holes in the dry seasons (they can easily locate water underground). They make paths in the forest by pushing brush and pulling down trees and also disperse seeds of fruits by depositing them in their dung.

3. What economic impact does it have on human society?
Endangerment affecting humans is due to the destruction of habitats there’s not enough food in the small forest for the elephants so they go and look for other food sources which are crops in nearby fields. Attempts were made to locate these animals but because of change in habitats they’ve raided villages and destroyed homes and crops not only do they pose a danger to human society we also pose a danger to them (1) they’re vulnerable to extinction because they have only few offspring and because of people always hunting them for their tusk and the deforestation and loss of their habitat.…...

Conservation of a Species

...One of the most endangered wild Canidaes on earth is the North American red wolf; known by the scientific name of Canis Rufus. The reasons for this are the lack of natural environment for them to roam, the lack of food due to human hunting, an intensive predator control program, and the interbreeding of the red wolf and coyotes in the wild. There is one thing that is being done to help the recovery of the species and that is the restoration program. That along with other projects could help bring back the red wolf from the brink of extinction. The red wolf is one of two wolves native to North America, the other one being the gray wolf. They get their name from the reddish tint they have in their fur mostly behind the ears and on the legs and neck. Their size is in between the coyote and the gray wolf. The average adult is around 4 feet long from the end of their tail to the tip of the nose, and 26 to 31 inches tall at shoulder height. Average weight is between 50 to 80 pounds. They tend to hunt alone or in small packs of 5 to 8 individuals; often the individuals are the pups from the breeding pair. The breeding pair or alpha male and female are likely to mate for life. The gestation period for the red wolves is 60 to 63 days, mating season is late winter and the litter size varies from 2 to 8 pups. Only having one litter a year could be seen as a problem but there is nothing that can be done to change that. Their diet consists mainly of small animals such as......

Egg collection was historically a major threats the population but since laws were placed in 1966 these has seized to be an issue. Kemp's Ridley turtles are protected by various international treaties and agreements. Some of these protection laws include the Endangered Species Act of 1973, Annex II of the Specially Protected Areas and Wildlife (SPAW ) Protocol of the Cartagena Convention, and the Inter-American Convention for the Protection and Conservation of Sea Turtles. Ways to protect the turtles include not purchasing turtle products such as turtle leather and tortoiseshell items. Rafflesia The Rafflesia is the largest flower on earth. It is a parasitic flowering plant. It has an average diameter of about 106cm (42.5in) and a weight of 10kg (22lb). They are located only in Southeast Asia, with only 15-19 known species. Rafflesias are technically part of the plant kingdom although they don’t have chlorophyll which means they are incapable of photosynthesis. Rafflesia is dependent on a vine called Tetrastigma, which is related to the grapevine. They grow as thread-like strands of tissue embedded within the surrounding host cells from where they receive their nutrients and water. The flower has a repulsive smell like rotting meat and many of the locals call it the ‘corpse......

Caulerpa Taxifolia an Invasive Species Essay plant that made the aquarium look very pretty? Don’t let this plants pretty color fool you; it is an invasive species in the wrong habitat. An invasive species is essentially an invasion altogether. In terms of ecology an invasive species is when either a plant or animal is introduced to a different area from their natural habitat and cause environmental or economical harm. Giving this definition I will discuss Caulerpa Taxifolia. Caulerpa Taxifolia is a macro algae invader that is a multicellular plant native to warm saltwater. It is one of the most invasive green alga in the seas. It is considered invasive because it has the ability to spread over large areas in the ocean while forming dense mats, causing ecological and economic issues such destroying sea weed, sea grasses, fishes, commercial fishing, boating. Caulerpa is a salt-water plant with structures that look jut like roots, stems and leaves. The roots of Caulerpa are called rhizoids, which grow into the ocean floor to absorb water and nutrients. Caulerpa have leaf like structures that stick up called fronds, which are a bright green color and are photosynthetic. The stems of Caulerpa are called stolon, which grow above the ocean floor; the stolon when fragmented grows a new Caulerpa plant. Its normal habitat is in tropical waters around the world such as the Indian Ocean. Caulerpa taxifolia is not invasive in its native habitat and reproduces sexually. Grazing marine predators that co-evolved with the alga......

Endangered Species

...Endangered Species Think back to the first time you went to the zoo. Do you remember the excitement you felt when you got your first glimpse of a tiger? Or maybe your favorite animal was an elephant. These species and many others are in danger of becoming extinct. I’m going to explain to you the process to get a species listed as endangered and the protective measures taken to help them recover. I’ll also talk about the success rate of these efforts. The first step to protecting a threatened species is to get them listed. The process to have a species added to the list can take up to a year. Species are listed by 2 classifications, threatened or endangered. A threatened species is a species that could become endangered in the near future without proper protection. An endangered species is a species that could become extinct. To start the process someone must first file a petition or conduct a survey of the species. Anyone can file a petition providing there is enough biological evidence to warrant further investigation. Members of the U.S. Fish and Wildlife Services or the National Marine Fisheries Service complete the surveys. Several factors help determine if a species is in need of protection. A few of those factors are: Changes in habitat, over utilization due to commercial and recreational purposes, disease or predation, and inadequate regulatory Laws. Within 90 days of receiving the petition or survey they must decide if further investigation is warranted. If it...

...January 18, 2014 iLab 2 – Week 2 – Ecosystems, Biodiversity, and Species Introduction This Lab covers ecosystems, food webs, and the transfer of energy between species. In includes a review of biomes and ecosystems along with the operation of food chains and food webs, looking specifically at how energy is transmitted through the food web as part of the biomass pyramid. 1. Discuss the producer, consumer and decomposer relationships in the Mount St. Helens ecosystem post eruption. a. Producer Relationships – the producer relationships suffered immediate damage in the immediate vicinity of the blast although for about 5 more years the effects spread to a much larger area due to the ash blanked deposited via prevailing winds. In year 9 there began to be notable recovery, in areas furthest from the blast, of producers (vegetation) which peaked in 2010. Even recently additional recovery is being shown in the most damaged areas as well through natural seeding and interaction with consumers. b. Consumer Relationships – Insects, as expected were some of the first to return. Interestingly enough small mammals actually were able to stay in the vicinity in many cases even in the harsh conditions. The large animals were wiped out however and have had to return slowly over time from the surrounding areas. It is important to not this was not a linier return to pre eruption populations rather the species went through several “boom and bust” cycles due to......

...rather than being all at the same rate in a plantation. 1d. The leaves may not decompose at all and rather become preserved or they may decompose fast. Most likely the leaves will get beaten up and stuck on branches and have a slow decomposition rate. 1e. Well you would expect them to vary, due to temperature change over seasons, the nutrient levels in the soil, amount of rainfall, sunlight, moisture level, species that are present, decomposers that are present to speed up decomposition rates. I would expect places that are warmer and with more moisture such a Virginia to have a higher decomposition rate rather than places in New York or Carthage. I would expect these two places to be very similar and not have much difference in decomposition rates, but it could be different as the New York does get more moisture from the ocean and the Great Lakes adding to precipitation. It all really comes down to moisture and precipitation. 2i. Mass that was lost in the decomposition it seem to be that the 100% invasive species had the most mass lost and the 75% native and 25% invasive lost the least amount of mass. 2ii. So, this was the average of the mass lost of the three data sets collected. There are 5 different average total lost, this makes it easier to look and summarize the data to see where the most mass was lost and which one retained the most. 2iii. This was determined by the average of mass lost divided by the number of days. This is to determine how much is decomposed per a......

Endangered Species

...Endangered Species Biological diversity, or biodiversity for short, refers to the variety of life across all levels of biological organizations, including the diversity of species (Withgott & Laposata, 2012, p. 49). Biodiversity at all levels is being lost to human impact, irretrievably when species become extinct. Once vanished, a species can never return. The International Union for the Conservation of Nature and Natural Resources (IUCN) Global Species Program along with the Species Survival Commission (SSC) and partners, such as the World Association of Zoos and Aquariums (WAZA), assess the status of species on a global scale for the IUCN Red List in an effort to underline possible extinction, thereby encourage their conservation (IUCN, 2014). All assessments or reassessments for publication on the IUCN Red List must use categories, such as Endangered (EN) and criteria (e.g., Continuing decline in EOO, AOO, habitat, locations or subpopulations, or mature individuals and/or Extreme fluctuation in EOO, AOO, locations or subpopulations, or mature individuals) as adopted by the IUCN Council (IUCN, 2014). In 2012, the Atrichornis clamosus (also known as Noisy Scrub-bird, Western Scrubird) was uplisted to Endangered (EN) on the IUCN Red List of Threatened Species. In questioning why, large lighting-induced fires and other small-scale unexplained events further declined population size and habitat quality on the south coast of Western Australia . However, these......

Endangered Species

...environmental law that I choose is Endangered Species Act. This Act was passed in 1973, to protect the extinction of or threatened species. Before I go any further let me define the difference between extinct and threatened species; • Extinction is the process by which a species die out, this means that all genetic buildup of that species is gone forever. Extinction can be the cause of Natural disaster, from human activities. • Threatened species are living organism that can become endangered in our nearby future. Endangered species represent the living species of plants and animals. That have become scarce, this means that they are in danger of becoming extinct. When an endangered species becomes extinct, this can interrupt the food chain or web. This will interrupts the production of new or improve medicine, we would loss that animal species forever because there is no genetic evidence left of that species. All this would be affected by the extinction of a species. The goal of the Endangered Species Act (ESA) of 1973 is to prevent extinction from happening. ESA was signed by President Nixon, The extinction of animals and plant species was brought about by Rachel Carson who wrote a book called Silent Spring (1962). Rachel warned about destroying wildlife with DDT in our environment. This is what prompted the enactment of the Endangered Species Preservation Act of (1966). This Act was made to protect nature species that were on the brink......

Species Diversity

...Benjamin Moore Dr. William Ross For301 6 February 3015 Species Diversity A diverse ecosystem is a stable ecosystem. Without it an ecosystem would have a much harder time recovering from disturbances and resisting perturbations. To measure diversity it is as simple as using a formula called the Simpsons Diversity Index. In the lab we surveyed two separate plots to calculate their diversity. In the species diversity lab we started off by taking a field trip from south campus to Wafer Creek Ranch. The purpose of the field trip was to split into two separate groups and measure the diversity on them. The two plots were marked off with biodegradable flagging and everything in the flagging was examined and recorded. To do the second plot we underwent the same instructions as on the first plot, but the plots were three chains apart. The information gathered on the field trip was then plugged into the formula and the diversity of the two plots was calculated. The results are in the following tables. Site 1 | | Total Trees | Diversity | Location | Sweetgum | 18 | 0.052 | Midstory | Honeysuckle | 1 | 0 | Understory | Water Oak | 1 | 0 | Understory | Smilax | 40 | 0.297 | Midstory | Red Oak | 4 | 0.002 | Understory | White Oak | 8 | 0.011 | Understory | Carolina Buckthorn | 1 | 0 | Understory | | Diversity= 1-.368 | | Site 2 | | Total Trees | Diversity | Location | Black Gum | 1 | 0 | Midstory | Black Cherry | 6 | 0.046 | Midstory | White......

...Lindsey Lebrick Bio 104 Dr. Stelzer Endangered Species in Wisconsin In previous years, the environment was looked at as an infinite resource. People did not realize their actions had negative effects on the environment and the species it inhabited. Such negative effects was pollution, which harmed animals and their living areas more than thought possible. It wasn’t until after events started happening, that people realized the harm they were inflicting. There were and still are many endangered species from this, however organizations and laws are now involved in the stabilization of these animals and prevention techniques. There are several endangered species in Wisconsin, however the first I am going to talk about is the Lycaeides Melissa samuelis, otherwise known as the Karner blue butterfly. These butterflies are federally endangered in the USA, at eleven sites at Fort McCoy, Wisconsin (Guiney, Androw and Wilder). The samuelis butterflies, both male and female have a wingspan of about one inch, but vary in appearance. The topside of the male is a silvery dark blue with black marks. The female is a grayish brown, especially on the outer portions of the wings. The females are wings are blue on the top and have irregular bands of orange crescents inside the narrow brown boarder. The underside of both sexes is gray with a continuous band of orange crescents along the edges of both wings and with scattered black spots circled with white. The Karner blue butterfly......

Origin of Species

...Origin of species- Natural Selection Natural selection is a slow process in which species with useful adaptations are more likely to survive and produce offspring than species with useless adaptations, by that, increasing the frequency of the biological trait in future generations. Since there is only limited amount of resources in the enviroment, it becomes a “competition” to find food, shelter and mates. The well adapted species will survive and continue to reproduce and those who are less adapted, will die out or fail to reproduce. This theory was proposed by Charles Darwin and Alfred Wallace, in 1858. (Encyclopedia Britannica, 2014) The process of natural selection has four factors: Inheritance, Where some traits are passed down from the parents to the offspring. High rate of population growth, limited recsources and more offspring will lead to struggle for survival. Variation, individuals of the same species will exhibit individual variation, even closely related individuals differ a great deal. Variations include, body size, facial features, eye and hair colour, height and weight. Differential survival and reproduction,  Individuals possessing traits that are well suited for the struggle of the limited will have more offspring (Encyclopedia Britannica, 2014). This factor is also known as “Survival of the Fittest”, a phrase often used by Herbert Spencer, an English philosopher and sociologist. Where fitness indicates an individuals ability to pass copies of its......

Harmful Effects of Invasive Animal Species on Terrestrial Habitats

...UK invasive species top facts * Invasive non-native species are thought to be one of the biggest threats to global biodiversity, second only to habitat loss. * There are almost 2,000 established non-native species in Great Britain. * Invasive non-native species cost Great Britain around £1.7 billion annually. * Invasive species have been introduced to the United Kingdom from every continent in the world apart from Antarctica. What is an invasive species? An invasive species is a species which has been introduced to an area outside its natural range and can cause a multitude of ecological, economic and public health problems within the new habitat as its population grows. Invasive species may belong to any taxonomic group, with mammals, reptiles, birds, amphibians, plants, invertebrates, fish and viruses all having invasive populations around the world. The extinctions of numerous species around the world can be attributed to the negative effects of invasive species. When a species is taken out of its natural range and placed into a new habitat it is removed from its natural predators and any pathogens which help to control its population. Without these, population growth may become out of control and the invader can rapidly colonise its new habitat. The characteristics which enable an invasive species to outcompete native species include fast growth, a short life cycle and the ability to tolerate a wide range of habitat types and environmental conditions.......

Endangered Species

... Endangered Species: Student’s Name: Instructor’s Name: Course: Institution: Date: This statement that "Eventually, all species become extinct" is true because life and death forms part of this universe that we live in, the earth. Anything that is born at one time it is going to die. In the same way, any species that is in existence is going to get extinct. But it does not mean that we need to forget our endangered species and let them get extinct.  For example, every human being who was born is soon going to die. That means your relatives and friends, also someday are going to die. If supposedly it happens that any of your relatives or friends meet with an unexpected accident or is admitted to hospital because of a disease then you will try to help save them. Everyone knows that one day they are going to die but you won't let them die so soon. You would want them to stay longer with you.  The same case applies for other species. Every species is going to get extinct at some time in the future. But as we want relatives and those people who are close to us like friends to stay longer, the same thing also should be done to other species.  With the global warming and climate changes issues that have not been solved, organisms are endangered since their habitats are being interfered with. Resources such as water and air quality are being polluted at a very faster rate than the conservation measures taken to save them. Water is one of the main sources of conflicts in most......

Species and Evolution

...Species and Evolution Rasmussen College Dana Voicinco G156/BSC1548 Section 02 Human Biology - Online – 2016 Winter Quarter A species is defined as a group of organisms, which, under natural conditions, tend to interbreed and produce fertile offspring. A species is the biggest gene pool possible under natural conditions. If we look different does not mean we belong to different species. Organisms may appear to be alike and be different species, or may look different and be considered the same species. Racial differences are just phenotypic differences between subgroups of human species, but there are no barriers to reproduction, and we are considered the same species. For example, many bacteria reproduce mainly asexually. The bacterium is reproducing asexually, by binary fission. The definition of a species as a group of interbreeding individuals cannot be easily applied to organisms that reproduce only or mainly asexually. Genes are what code for the traits of an organism, and the offspring inherits at least some of the genes from the parent. Genes are the portions of an organism's DNA that carry the code responsible for building that organism in a very specific way. From generation to generation, molecular mechanisms reshuffle, and alter genes in a way that produces genetic variation. Without genetic variation, the basic mechanisms of evolutionary change cannot operate. Natural selection is one of the basic mechanisms of evolution. Natural selection......
