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 Oak | 7 | 0.065 | Midstory | Mockernut HIckory | 1 | 0 | Midstory | Smilax | 5 | 0.031 | Understory | Black Oak | 1 | 0 | Midstory | | Diversity=1-.745 | |

The plots used in this lab were both similar and different in several ways. The plots are the same in the fact that they have virtually the same species in them. The plots both have several different species of oak in them as…...

...life. Besides being an important natural site in Singapore, what makes it even more unique is that it holds a significant position in Singapore’s natural heritage as the location where the battle for Pasir Panjang took place. (H.T.W. Tan et al.). The walk also enlightened me about how human actions affect the vegetation of a forest, as I realised the changes Kent Ridge forest had undergone due to man’s actions. Kent Ridge was originally a lowland evergreen rainforest, specifically a coastal hill dipterocarp forest. (H.T.W. Tan et al.). Such forests were the most common in areas with year-long moisture and well-drained soils, as found in Singapore. (R.J Morley). Such forests are dense, and lack ground plant growth. They also have a higher diversity of flora and fauna as compared to other forest types. Due to clearance of the forest by man for the cultivation of rubber, pepper and pineapple crops in the past, the forest had lost its original vegetation. Other kinds of vegetation then grew in the ground that had been previously disturbed, forming the secondary forest. The secondary forest vegetation differs from the primary forest vegetation due to the different conditions that are present. Some of the changes in conditions include higher light intensity, higher temperatures and lower humidity. These changes are mostly brought about due to the lower plant density. As such, the vegetation that is growing adapts to the different conditions through various mechanisms. One such......

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......

...line and trap/pot fishing gear. Once they are tangled up they may drown and often suffer serious injuries to their flippers from constriction by the lines or ropes, which ultimately lead to death. 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......

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...

Invasive Species

...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...

The Effect Climate Change Has on a Species

...Bio-100-131 17 July 2013 The Effect Climate Change has on a Species As Earth’s climate cycles between warm and cool periods, species often must move to stay within suitable conditions. Scientists have now mapped how fast species have had to migrate in the past to keep up with changing climate. They found that small-ranged species – which constitute much of Earth’s biodiversity – are concentrated in regions where little migration has been required (Science daily). With people activities and habits, are changing their climates at an extremely fast past. What happens if a species cannot migrate as fast as it must to keep up with the velocity of climate change? Its range may shrink and, in some cases, the species may go extinct (Science daily). This research provides the first evidence that past regional climate shifts interact with local topography and species dispersal abilities with long-lasting important consequences for the global distribution of biodiversity (Science daily). Earth’s climate 21,000 years ago was much colder than it is today, this caused many of the species that are still found today to occupy different areas than they do now. In northern Europe, for example, many of the species found today are relatively recent arrivals from their refuges in southern Europe (Science daily). Many regions to include most of Africa and parts of the Amazon are going some of the leading places that are going through the most increased climate-change. These areas are......

The Lesser Known Species in Florida

...Florida: More than Just Alligators and Manatees Josue Cajina COM/172 May 26, 2014 Nora Clarke Florida: More than Just Alligators and Manatees There are many species of animals in Florida of which the panther, alligator, crocodile, and manatee are the most popular, but there are other species equally interesting and beautiful, as the river otter, beaver, fox squirrel, key deer and over 500 different types of birds ("Great Florida Birding and Wild Life Trail", 2014). Although some of these species of animals are found in other states, Florida natives are unaware of the fauna diversity in their own backyard. The state of Florida offers 11 national parks ("National Park Service", n.d.) where both natives and tourists can spot these animals. For this reason, teaching people about Florida's lesser known animal species can help increase visits to Florida's National Parks, encourages outdoor activities, and raise conservation awareness in this state. Florida has both native and non-native animal species, but out of the native the most recognized species may be the alligator and manatee. Florida is home to more than just that and teaching people about its lesser known species can promote visits to Florida's National Parks. As mentioned earlier, there are 11 national parks ("National Park Service", n.d.) throughout the state, featuring the Everglades, which the National Parks Service describes as "The largest subtropical wilderness in the United......

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......

Endangered Species

...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......

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......

Endangered Species in Cambodia

...Endangered Species in Cambodia Source: http://cambodia.panda.org/wwf_in_cambodia/endangered_species Special thanks to: Samnang SAN Student of Faculty of Forestry, Royal University of Agriculture for providing Khmer names to some of the wildlife below. Just 50 years ago, large herbivores like Banteng, Asian Elephant, and Eld’s Deer as well as predators like Indochinese tiger and leopard were so abundant in the Dry Forests of North and Northeast Cambodia that scientists compared this ecoregion to the savannas of East Africa. In the troubled decades that followed, however, habitat destruction and hunting greatly reduced animal numbers and diversity. Today, the largest intact dry forests in Indochina remain in north-eastern Cambodia in an area known as the Eastern Plains Landscape (EPL). Cambodia large variety of habitats both on land and in water are home to a significant diversity of threatened wildlife species. Among mammals, wild cattle and deer species as well as predators like tiger and leopard still roam the remote forests of the Eastern Plains Landscape, while a small population of Irrawaddy Dolphin inhabits the Cambodian section of the Mekong River. Birds are equally plentiful - especially Cambodia's populations of large waterbirds in both forests and wetlands stand out as globally significant. The Mekong River is also home to several endangered and iconic fish and reptile species, and critically endangered Siamese crocodile have been......

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......
