- Fill in the missing words in the following. The organisation responsible for publishing the "Red List of Threatened Species" is the International for of . In your response state the three words in the correct order with a space between each word.
- Consider three different species of wild cats. Populations of species A are spread evenly across Africa, species B is scattered around the whole of Australia but its population is relatively large in numbers and the population of species C lives on a single island in the Southern-Asian region. Which of the three species is the most prone to extinction?
- Human activities that overexploit natural resources (such as deforestation) pose a major threat to biodiversity. Which environmental value system would be the most likely to engage in such activities and ignore the threats to biodiversity they pose?
- Choose which of the following pairs of criteria would be taken into account when determining the conservation status of a species:
- If the midlatitude cyclone described in Question 1 took 3 days to pass your location, on which day would temperatures likely be warmest? On which day would they likely be coldest?
- What general atmospheric conditions are most conducive to the formation of tornadoes?
- What winter weather might be expected with the passage of a mature midlatitude cyclone when the center of low pressure is located about 100 to 200 kilometers (60 to 125 miles) south of your location?
- During what months is tornado activity most pronounced in the United States?
- Briefly describe the weather associated with the passage of a mature midlatitude cyclone when the center of low pressure is about 200 to 300 kilometers (125 to 200 miles) north of your location.
- What is the name of the flow which becomes limited when populations are geographically isolated?
- What is the name of the only place where, as a result of the isolation of gene pools and speciation, lemurs can be found today?
- All species have a natural extinction rate, which is referred to as the background extinction rate. What is the approximate value of this rate (how many species go extinct per year) ?
- The background extinction rate is a measure of the natural extinction of all species. Knowing that the range of the background level of extinction is between X and Y per year, substitute the letters with numbers illustrating the correct values.
- Organisms can colonise isolated land through different mechanisms. What are the types of species dispersal? List three in alphabetical order. Do NOT use capital letters at all.
- The process of natural selection may also be described as:
- During which geological era(s) did all land mass on the Earth exist as one supercontinent? What is the name of that continent?
- According to the fossil records, there have been five mass extinctions on the Earth so far. Choose which answer lists all of them in order of occurrence.
- Which of the following human activities is particularly dangerous for such species as elephants, chimpanzees, rhinos or alligators?
- How many mass extinctions have so far occurred in the history of the Earth?
- How can deforestation threaten the biodiversity of a rainforest?
