Diversity Index Lab Introduction: The measure of the biodiversity of organisms in a given area is known as the diversity index. The diversity index values will vary between 0‚ which would indicate no diversity‚ and 1‚ which is very diverse. Any values above 0.5 usually indicate a relatively diverse population. For example‚ a healthy forest or woodland should have a diversity index of 0.7. An area that is not very diverse‚ like a cornfield‚ might have a diversity index of 0.02 or less. In this

A study of palaeontology and past environments increases our understanding of the possible future range of plants and animals Explain the importance of the study of past environments in predicting the impact of human activity in present environments: • The knowledge gained from palaeontology (fossils) and the study of past environments can help us to understand present day ecosystems • This knowledge can be used to predict and determine the future for Australia’s plants and animals • Palaeobiologists

There is not just one causative factor to blame for this devastating news; there are many potential causes that are resulting in these numbers. The various declines can be linked to countless natural forces such as predation‚ competition‚ disease‚ habitat destruction‚ environmental contamination‚ deformities‚ change‚ invasive species‚ and unfortunately the list can continue to go on.

The Rattus Rattus (black rat) is one of the most problematic invasive species in the world. Covering 80% of all archipelagos and are found on six continents. Black rats are mainly found on tropical islands such as the Galapagos‚ Hawaii and most of the islands in Central America. Rats prefer to live in areas filled with forests and shrubland‚ but can live on minimal vegetation. Scientists have been able to exterminate this invasive species from most temperate and sub Atlantic islands because of the

Carl Sagan asked‚ based on his cosmic calendar‚ “Where would you place your own life on this timeline? Where would you place the life of one of your grandparents? What is the major disadvantage of a time line drawn to this scale? What is its advantage?” To answer his questions about where your life or the life of your loved ones would fall‚ signifies a miniscule amount of time relative to the time line of human history. You simply couldn’t place the life of any single human on this cosmic calendar
