Spatial Ecology of the Iguana iguana in the Mangrove Ecosystems of Puerto Rico.

  1. 1. Spatial Ecology of the Iguana iguanain the Mangrove Ecosystems of Puerto Rico.<br />JesykaMeléndez Rosa<br />
  2. 2. The Iguana iguana, of the family iguanidae, is by definition an introduced species of reptile originally native to Central America, South America and the Caribbean.<br />It’s recently growing populations on island have made them an increasingly popular subject to the media.<br />Introduction<br />

  11. 11. Because these iguanas are in a new habitat, <br /> Is it possible for them to develop different behaviors? <br /> And what is their home range?<br />Main Question<br />
  12. 12. This semester:<br />We captured a total of seven new iguanas in order to expand our sample pool and acquire more accurate data.<br />
  13. 13. We used our original method for the attachment of the radio transmitters with the use of:<br /><ul><li> PVC strip
  14. 14. Fishing crimping tubes
  15. 15. Nylon coated fishing string
  16. 16. Thick sewing needles
  17. 17. Colored permanent markers
  18. 18. Transmitters (model- F2000, ATS)</li></ul>For the smaller transmitters we used:<br /><ul><li>Beads to attach charms
  19. 19. Large fluorescent red fishing beads </li></ul>Methodology<br />
  20. 20.
  21. 21.
  22. 22. Collecting of seven iguanas.<br />Attachment of radiotransmitors to iguanas.<br />Return of iguanas to collection point.<br />Monitoring of radiotransmitors was done rigorously for the first month and will be done sporadically from then on. <br />Data will be analyzed using special telemetry software.<br />Maps will be created using a geographic information system software.<br />Methodology- Telemetry<br />

  24. 24. Google Earth<br />
  25. 25. Google Earth<br />
  26. 26. Iguanas are more abundant in border areas adjacent to human settlements. <br />They are very sedentary animals remaining within a few meters of their capture zone. <br />Hypotheses<br />
  27. 27. <ul><li>Make a detailed description of the Iguana iguana home range and create maps.
  28. 28. Analyze data and determine the correlation, if any, between sex, sunlight and movement.</li></ul>Short Term Goals<br />
  29. 29. By studying and determining the iguanas home range;<br /><ul><li>Develop future conservation and management systems.
  30. 30. Monitor population behavior; natality and mortality rates, migration, etc.
  31. 31. Provide overall insight into the behavior of these misunderstood animals.
  32. 32. Discover changes in behavior, if any, due to habitat change.</li></ul>Significance<br />
