Botany 431 - Physiological Plant Ecology

At the end of your study this week, you should be able to achieve the objectives listed below. You must assemble the evidence that you have achieved these learning outcomes into your Portfolio. You should provide evidence that would be regarded as performance at the top two levels of Biggs' SOLO Taxonomy.

The material in your Portfolio will be assessed as Project 1.

If you wish to discuss this material informally with your peers, you can interact in Esme's Coffee Shop.

You can also challenge your peers by posting questions for them to respond to on the Student Quiz Board.

Week One - Learning Objectives

When you have completed this section you will be able to:

  1. List the different instruments used to measure radiation in physiological ecology research. Identify in what units they measure radiation.

  2. Expain the need to measure radiation falling on a plant in energy units or in terms of the number of photons present.

  3. List the processes by which radiation impinges on a plant and those by which plants emit radiation.

  4. Explain the consequences for the plant when the incoming and outgoing radiation fluxes are unequal.

  5. List the methods physiological ecologists use to measure temperature and humidity in plants and communities.

  6. Explain the relationship between temperature and relative humidity.

  7. List methods for the measurement of wind speed.
