Biodiversity

Rainforests are an oasis for biodiversity. They cover only 7% of the earth’s surface, yet they are home to about 50% of the world’s species. However, past and recent human impacts on these forests can have devastating effects. One of the most prevalent issues being climate change. In order to truly understand the magnificence of rainforests, let’s take a look at the largest rainforest in the world: The Amazon. The Amazon spans over 5.5 million square kilometers in parts of nine different countries

Population Evolution DNA technology with forensic science is when samples are analyzed to determine if they are from the same individual which is also known as DNA profiling. The term biotechnology is defined as the manipulation of living organisms to perform useful tasks which today is called DNA Technology. To produce a DNA profile, scientists compare sequences in the genome that vary from person to person (Simon, Dickey, & Reece, 2013 p.262). DNA profiling and forensic science is an overview

Currently, the sagebrush ecosystem is rapidly declining across the Western United States, with over 350 associated plant and animal species at risk of being lost and imperiled. The main reason for the sagebrush decline is the steady encroachment of cheatgrass and pinyon-juniper. The invasion of these plants are fueling larger and more frequent fires that are out competing sagebrush as well as the associated grass species that are native components of the ecosystem, taking over much land that sagebrush

As the world develops and the human population grows there is more pollution being dumped into the oceans, causing major problems to marine life and ecosystems. Major causes of marine pollution involve non-point pollutants, marine garbage, toxic ocean pollutants and sewage disposal in oceans. From heavy metal poisoning including lead and mercury killing predators such as sharks and whales, to waste getting trapped in the digestive tracts of marine animals, this essay focuses on how human interference

Name Subject Date Biological Applications Population evolution and microbial life are a major component in biological applications today. Microbial life is being discovered everywhere and these microbes can have major positive and impacts on society. Some microbes can promote increased human immunity to certain diseases like Cancer (Green and Ariyan 2014) or can potentially decrease the human aging process (Ghose 2014). For example, current clinic trials are now using microbes to help increase

CHAPTER FIVE 5.0 The Impact of Fragmentation Process on Genetic Diversity and Gene flow. Fragmentation impacts on gene and genetic function are likely to reduce ecosystem stability through reducing resistance and resilience. Resilience describes the speed with which a system returns to its former state after displacement, while resistance is its ability to avoid displacement to begin with (Begon et al., 2005). Forest fragmentation has three main effects on species diversity a) Reduction of overall

Nevertheless, the larger correlation between biodiversity and cultural diversity does seem to persist in different studies of different regions. Such as, in Nabhan, Pines et al. in their 2002 article on “Safeguarding Species, Languages, and Cultures in the Time of Diversity Loss” look instead at a different

Overview and Mandated Provisions The Wildlife Innovation and Longevity Driver (WILD) Act was introduced with the aim of improving and maintaining global biodiversity by addressing four critical issues: habitat loss, invasive species, and wildlife poaching/trafficking. The WILD Act addresses these issues through four provisions: 1) establishing the Theodore Roosevelt Genius Prizes, 2) reauthorizing the Multinational Species Conservation Funds (MSCF), 3) amending the Fish and Wildlife Coordination

A keystone species is a species that has such a large impact on the ecosystem that without it other species couldn’t survive. A famous example of how keystone species affect the ecosystem can be the influence that wolves have on Yellowstone’s biodiversity. Without wolves, the ecologic balance in the park would be compromised: their absence would result in the overpopulation of elk, which causes a decrease of the vegetation to almost nothing. Canis lupus, also known as gray wolf, is the largest

The biome ecosystem of the rainforest is a wonderful place, full of animals, color, and life. It has the largest diversity of living organism and plants on earth, with rich biodiversity. The Rainforest supports about 50% of the plants and animal living on earth. The rainforest is located in a tropical region. This allows them to receives lots of sunlight, giving plants the energy they need and a wide variety of food for the organisms. The rainforest provides an abundance of sources of shelter, food
