Species Interaction * The relationships between two species in an ecosystem. * The interactions between two species need not be through direct contact. Species may affect each other through intermediaries such as shared resources or common enemies. Major factors in evolution and adaptation: * Predation * Competition for scarce resources Terminologies: * Habitat – the actual physical location where a species lives. * Conditions – physical or chemical attributes of the

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

Casey Sullivan Mrs. Stephens English 1101 23 April 2013 Dangers of Invasive Pythons in Florida To analyze the dangers posed by pythons in Florida‚ one looks at the information on case study‚ location‚ statistics‚ dangers to the ecosystem‚ methods of control and laws. It is a fact that large pythons do pose a major threat to numerous aspects of life. Wildlife biologist Skip Snow states‚ “We’re bringing them into the country under the idea that they’re all innocent until proven guilty” (Kessler

Many believe that humans are the perfect species. Many believe that no other species in the universe can compare to the intellect and emotional stability of humans. Although this is the popular belief for the majority of the public‚ many philosophers say this is not the case. Humans are far from perfect and various authors and journalists‚ directors and philosophers exemplify how humans are flawed daily through their works. Alexandre Dumas and Homer are two particular authors/philosophers that not

Amphibians are becoming a vanishing species. There are a number of causes for them dieing. But the most recent and worst cause has been discovered. It is responsible for killing off our amphibians. They are dieing by the thousands. They were able to survive and hold on through past extinction spasms‚ surviving even when 95 percent of other animals died out. They even stayed alive when the dinosaurs disappeared. If amphibians could live longer than dinosaurs‚ then why are

A keystone species is defined as one that has a critical role in determining and maintaining the overall relationship of plants and animals within an ecosystem. If a keystone species is removed or declines‚ the nature of the ecosystem will change dramatically. Sea Otters — A Classic Keystone Species The classic tale of a keystone species is that of the sea otter‚ which was once found in abundance along the West Coast of North America. The story goes something like this: 1. European and

relatively few species from many different classes of Ascomycota‚ whereas tropical endophyte assemblages are dominated by a small number of classes with a very large number of endophytic species. The most easily cultivated endophytes from tropical plants have wide host ranges‚ but communities are dominated by a large number of rare species whose host range is unclear. Even when only the most easily cultured species are considered‚ leaves of tropical trees represent hotspots of fungal species diversity

First published on November 24‚ 1859‚ The Origin of Species (full title On the Origin of Species by Means of Natural Selection‚ or the Preservation of Favoured Races in the Struggle for Life) by English naturalist Charles Darwin is one of the pivotal works in scientific history‚ and arguably the pre-eminent work in biology. In it‚ Darwin makes "one long argument‚"with copious empircal examples as support‚ for his theory that "groups" of organisms‚ (now called populations) rather than individual organisms

measures of controlling this invasive species includes decreasing the defragmentation‚ and the creation of edges in which the DSV and other invasive species like the garlic mustard may flourish (Foster and Sandberg 2004). By outcompeting the native species‚ the DSV and garlic mustard are a danger to the native grasses and plants. DSV disrupts the food webs and breeding patterns of the monarch butterfly and put the species at risk (Mattila and Otis 2003). Other invasive species can introduce disease and
