Keystone species are species of animals that other species and the entire ecosystem depend on. Sea otters and elephants both play major roles in their ecosystems‚ as they are both keystone species. Without these two species‚ their ecosystems would have drastic changes in the environment in which many organisms and species would not be able to survive. If the sea otters and elephants were to leave the ecosystem it would cause a domino effect. The domino effect would make other species disappear

Western Diamondback Rattlesnake Rare and much more fascinating than any other snake in its biome the Western Diamondback Rattlesnake is a heavy bodied snake with a rectangular shaped head and two dark diagonal lines on each side of its face running from the eyes to its jaws. With its dark diamond shaped patterned back and black and white bands just above its rattles. This intriguing and luring skin texture is pretty to look at however it is a venomous pit viper found in the southwest. Their name

substantial fluctuations in environmental conditions over the past 18‚000 years. E.g. Climate change and rising sea level. Classifying Ecosystems Classified according to their dominant features. Land based ecosystems = terrestrial ecosystems or biomes. (Forests‚ deserts‚ grasslands). Differences between terrestrial ecosystems primarily arise from variations in average temperature and precipitation. Water based ecosystems = aquatic ecosystems. (Ponds‚ lakes‚ rivers‚ oceans‚ wetlands‚ coral reefs)

The only feline to hold the honor of “critically endangered with extinction” is the Iberian Lynx‚ also known by its specific name‚ Lynx Pardinus. ("The Murry Foundation”) The Iberian Lynx lives in the Mediterranean woodland biome throughout Spain and Portugal. Its territories are around twenty square kilometers and they mark their boundaries with a scent. ("Lynx Pardinus") The Iberian Lynx is significantly smaller than the Eurasian Lynx with an average height of forty to fifty-one centimeters and

Overpopulation is a generally undesirable condition where an organism ’s numbers exceed the carrying capacity of its habitat. Overpopulation can result from an increase in births‚ a decline in mortality rates‚ an increase in immigration‚ or an unsustainable biome and depletion of resources. (Wikipedia) II. Why is it a problem? It’s a problem because the people are suffering and forced to live in the streets. There’s too many of us and the Philippines is just small so it couldn’t afford to carry all

likely at much shallower depths than the adult and upon metamorphosis into adult form they descend to deeper waters. Other information: They are found off the coast of California and the North Pacific region‚ mainly at the depth of 3330ft. Their biome is marine; from open oceans to high water marks and into estuaries. Bibliography * Bebaychna Rai. "Barreleye Fish." Barreleye Fish. N.p.‚ n.d. Web. 14 Oct. 2012.

Climate Change 200 Global climate change is possibly one of the most significant environmental issues facing our society. It has been recognised as a global concern by the Intergovernmental Panel on Climate Change (IPCC) (2002 Global Ecology and Biogeography). A case study of the Kosciuszko national park in Austrailia demonstrates the effects climate change can have on a protected area. The alpine zone around Australia’s highest peak‚ Mt Kosciuszko is of high scenic‚ scientific‚ education and
