Biodiversity and Evolution L2

• what human activities decrease the Earth's biodiversity?

  Deforestation, illegal hunting, mining, kaingin, overhunting, pollution
• What is the classification given when the species have yet to be sufficiently evaluated due to inadequacy of information?

  DD; data deficient
• It is a form of artificial selection that involves crossbreeding varieties within the same species to enhance desired traits?

  Selective breeding
• the golden skiffia is a fish that was believed to be extinct from its natural habitat. It was later confirmed that species of these are still found in captivity. IUCN will most likely classfiy this under what?


  EW; Extinct in the wild
• an example of a vegetable that was artificially selected from a species of wild mustard.

  Broccoli, cauliflower, cabbage
• an example of a keystone species.

  sharks, sea otters
• what do you call the specific ecological role of each species in an ecosystem?

  Niche
• who is considered as the "Father of evolution"?

  Charles Darwin
• what do you call organisms that out-competes the native species and can cause ecological problem?

  Invasive species.
• what do you call species found only at a certain specific location/place?

  Endemic species
• the measure of whether a particular ecosystem is numerically dominated by one species or are all represented by similar numbers of individuals.

  Species evennes
• the variety of different habitats, communities and ecological processes.

  ecosystem biodiversity
• The biological and chemical processes such as energy

  flow and matter recycling needed for the survival of species,

  communities, and ecosystems.

  Functional diversity
• • the range of different inherited traits within a species.
  • The variety of genetic material within a species or a population.

  Genetic Diversity
• • The number of different species in a certain community
  • The number and abundance of species present in different communities
