Shannon Angus Mrs. Cumbee January 9‚ 2013 Foreign Invaders Invasive species are groups of organisms that are unnaturally occurring to an area. When introduced‚ they can cause economic and physical harm to humans and ecosystems. The importing‚ legally and illegally‚ of invasive species into our society is not only harmful to our population and our ecosystem but also the population of plants and animals in their indigenous homeland. To continue‚ the smuggling of plants and animals into new

Juliet C. Rosauro BSBA-MM 2-4D Loss of Biodiversity: How many species are endangered ? ENDANGERED SPECIES: has so few individual survivors that the species could soon become extinct overall or most of its natural range. Characteristics of Extinction-Prone Species: -Low reproductive rate -Specialized feeding habits -Feed at high trophic levels -Large size -Limited or specialized nesting or breeding areas -Found in only one place or region -Fixed migratory patterns -Preys on livestock

Question 1 How significant are mass extinctions to living organisms? Mass extinctions are very important events to the living organism. When mass extinction happens‚ it will create huge impact toward the world‚ negative or positive. For the conservation biologist‚ they usually think this is a great loss. On the other hand‚ from the evolutionary perspective‚ mass extinction could be something good and bad at the same time. Mass extinction would end a lineages and the unique genetic vitiation will

Human activities that may affect water ecosystems such as oceans FISHING Reducing the fish communities in rivers and oceans‚ destructive fishing techniques can also cause water pollution and damage to coral and other aquatic life. Destructive fishing techniques involve the use of dynamite or cyanide; trawling in coral-rich ecosystems; bottom trawls that are dragged along the ocean floor‚ also disrupt and damage critical habitats. DUMPING Coastal communities have long used oceans as dumping grounds

I visited the Human+ The Future of Our Species exhibition that revolves around the innovations in genetic engineering‚ biotechnology‚ and nanotechnology. Cyborgs‚ superhuman or clones are everywhere around us‚ are part of us even. There are four sections of Human+‚ and I will discuss specifically on the exhibition that examines artificial intelligence (01: Augmented Abilities)‚ and assisted reproductive technologies (04: Life at the Edges). Across all divisions‚ one pertinent subject highlighted

Diana Arrowood BIOL-100 October 23‚ 2011 Nathan Varano The Extinction of the Grey Whale The overexploitation of a species is a factor that mankind is now growing a great concern. With advancing technology the fishing industry has catapulted its pace at capturing the treasures from our seas. With the high demand of the public consumers wanting shrimp and fresh seafood the supply of these species is diminishing. There are also fishing expeditions of fresh and saltwater that are being trapped

Human Cyborg In “The Next Species of Human” by Juan Enriquez talks about engineering cells‚ engineering tissues and making robots. Cells will be programmable in the future. There was one project in science fair where a student took the good substance from wine and put it into beer. For tissues engineering‚ humans can now grow teeth in petri dishes‚ and implant them in mouth. Regrow ear and bladder‚ and by using stem cells they can make a heart beat. Robots are being tested to fly‚ walk and they are

Amber Stout Pd. 6 Invasive Species Do you know how many invasive species there are in Hawaii? There are over hundreds and they are disrupting and damaging our ecosystem costing us millions of dollars to repair. Invasive species are a major threat to our environment and we need to stop them before they take over. Here are a few Invasive species in Hawaii. The Hypnea Musciformis (also know as Hookweed) is a reddish brown seaweed that has large hooks at the end of its branches

great danger or difficulty‚ the moment when things change and either improve or get worse. This meaning has been taken from the Oxford Dictionary. Thus‚ biodiversity crisis means the large number of different animals and plants are decreasing or in other word it’s facing extinction or becoming endangered. It also means that the large number of animals and plants are in a great danger. LOSES OF BIODIVERSITY Some species that are more vulnerable to extinction than others include species at the

Theories For The Extinction of Dinosaurs Theory Evidence They’d been around too long and just ran out of ways to evolve. The dinosaurs were a group of organisms that lasted around 180 million years‚ evidence suggests that these organisms ran out of ways to evolve and as a result could not cope with changing conditions. They were poisoned by the newly evolving plant life which produced chemicals to protect themselves from predation. This theory is plausible as it ties in with the first one‚ as the
