Problem of the extinction of many rare species The problem of the extinction of many rare species is becoming more and more serious in the recent years‚ so the governments of the world have established many nature reserves to protect these species. Chongming Dongtan Nature Reserve is one of the most important wetland kinds of national nature reserves. Chongming is the world’s largest alluvial island which is formed by the mud and sand silt where the Yangtze River and East China Sea collide‚ is growing

time. The evolution of our earth‚ and it species has been a very debated topic over time. There is a lot of evidence that supports evolution and you have found a lot of great evidence that proved this theory to be true. The proposal that species variation locally‚ globally and over time was your idea‚ and is agreed with widely today. Natural selection is one of your other theories that is known all over the world today. Both natural selection and species variation have helped develop the theory

Plant species recognition is a prominent research area similar to Face recognition problem. Plant species recognition done through image processing has common obstacles in images such as illumination‚ viewpoints‚ orientation‚ background colour variations. Apart from this plant species recognition is hard since it has many species with inter-class and intra-class variations. To solve these problems‚ a backpropagation neural network (BPNN) has been created. This BPNN model contains an input layer‚

of the story‚ and do not get a chance to see the bad side of things. For example‚ many people view Christopher Columbus as a great hero who discovered the Americas and showed the native people new things. In reality Columbus’s expedition hurt the indigenous people more than helped. Once the explorers got to the new land they saw it as an economic potential‚ a way to make money off the native people. This would be an easy task at first because of the technological advances and the superiority of these

idea of bringing back a species from extinction throughout his essay. With examples such as the Pyrenean ibex‚ mammoths‚ passenger pigeons‚ and gastric brooding frogs‚ he discusses how technology and science have advanced to the point that de-extinction is close to being a reality. Zimmer then shifts to the benefits and problems that could arise if we are able to revive an extinct species. As a result‚ Zimmer raises the question that should we bring back an extinct species just because we can? Even

Indigenous Prison Population The overall prison population in Australia is similar to other developed countries‚ however the Australian Indigenous prison population is at an unacceptable rate and is continuing to rise (Krieg‚ 2006). The population of Indigenous prisoners in Australia has doubled within a generation (Mc Coy‚ 2008). Indigenous prisoner population in Western Australia‚ as with the rest of Australia‚ is massively over-represented (Justice & Community Safety in Western Australia‚ 2013)

Word Count: 1766 The Arguments in the Origins of Species Evolution involves organisms developing better adapted traits over time. Darwin explains how these specific traits come about through his “one long argument.” In this paper‚ I argue that Charles Darwin’s approach to natural selection is the most accurate depiction of our earth’s history. I begin with a breakdown of Darwin’s theory of evolution‚ then incorporate Darwin’s thoughts on “fitness” and why other scientists may contend against them

Ivan Chavez B1 Invasive Species: The Mexican Fruit fly An invasive species is a species that does not naturally take place in a particular area and with its arrival brings economic‚ environmental or human harm (1). Recently there has been a bigger emphasis on invasive species (1). They are threatening our agriculture and forests and causing major impacts to our cities (1). The characteristics that make the species thrive in their environment vary with each. Their characteristics

Our ecosystem relies on the basis of food chains. Food webs work through a series of food chains that link together. Invasive species are a part of our food web. Invasive species pose a great threat to the habitat of the existing native organisms. They can cause major disruptions to the existing habitats and so it is important to be able to stop their damage. Invasive species can be found in many different habitats including land and water. If the population of a given habitat increases‚ then there
