WRL reference M01 D01
Module M01 Ecosystems – Coral Reefs
Data set D01 The effect of light on coral morphology in the Caribbean
Research questions
  1. How does the common Caribbean coral Montastrea cavernosa modify its morphology in response to different light conditions?
  2. Can we use corallite density data to predict a maximum depth at which Montastrea cavernosa would be expected to be found on this coral reef?

Summary This task looks at the effect of light/depth on the morphology of a named coral species.  Analysis is via photographs (it could be an individual or group activity) and the data is plotted and analyzed using a spreadsheet – full instructions are provided.  The statistics can be approached at a number of levels, from plotting graphs to an introduction to regression analysis.  The task is supported by a number of powerpoint presentations etc.
Difficulty:
Research Q1 – 5/10
Research Q2 – 8/10 for advanced statistics
