Danum Valley Field Course

  1. 1. Tropical Rainforest Biology Field Course. Sabah, Borneo Aug/Sep 2009
  2. 2. Location <ul><li>Danum Valley Field Centre </li></ul><ul><li>Sabah, Borneo </li></ul><ul><li>Malaysia </li></ul>http://www.searrp.org/danum_location.cfm
  3. 3. The Site <ul><li>Primary Rainforest – completely untouched by logging. </li></ul><ul><li>Secondary Rainforest – areas </li></ul><ul><li>that have been logged in the </li></ul><ul><li>past. </li></ul>
  4. 4. Activities <ul><li>Night Walks/Drives </li></ul><ul><li>Moth Trapping </li></ul><ul><li>Canopy Walk </li></ul><ul><li>Trekking </li></ul><ul><li>Research </li></ul>
  5. 5. Research <ul><li>Number of group projects focusing on rainforest ecology. </li></ul><ul><li>Various activities to understand rainforest conservation. </li></ul><ul><li>Final group project of own choosing. </li></ul>
  6. 6. Final Project <ul><li>“ Young red leaves undermine herbivore camouflage as a defence mechanism.” </li></ul><ul><li>“ Worms” made from either red or green plasticine. </li></ul><ul><li>“ Worms” placed on same and opposite colour of young leaves. </li></ul><ul><li>Next day checked whether each individual “worm” has been predated. </li></ul><ul><li>If so, the predator is identified. </li></ul>
  7. 7. Final Project Results <ul><li>Green “worms” predated 4x more on red leaves than on green. </li></ul><ul><li>Red “worms” predated 2x more on green leaves than on red. </li></ul><ul><li>Ants were the major predators, followed by rodents. </li></ul><ul><li>A number of “worms” were taken so predator was unidentified. </li></ul>
  8. 8. Conclusions <ul><li>Red leaf colouration undermines green herbivore camouflage. </li></ul><ul><li>Red leaf colouration on young leaves is a defence against herbivory. </li></ul><ul><li>Predators able to more strongly distinguish green against a red background than vice versa. </li></ul><ul><li>At the time no similar experiments had been carried out. </li></ul>
  9. 9. Skills <ul><li>Hypothesis testing </li></ul><ul><li>Experimental design </li></ul><ul><li>Collecting field data </li></ul><ul><li>Data analysis </li></ul><ul><li>Teamwork </li></ul><ul><li>Oral/Written Presentation </li></ul><ul><li>Insight into tropical rainforest ecosystem </li></ul><ul><ul><li>e.g. community structure, biodiversity. </li></ul></ul>
  10. 10. Rainforest Topics <ul><li>Key ecological characteristics </li></ul><ul><li>Problems of Logging </li></ul><ul><li>Replanting the forest </li></ul><ul><li>Importance of community structure and species co-existence </li></ul><ul><li>Methods of conservation </li></ul>
