    Spatial Ecology Of The Iguana Iguana in the Mangrove Ecosystems of Puerto Rico Spatial Ecology Of The Iguana Iguana in the Mangrove Ecosystems of Puerto Rico Presentation Transcript

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

    • Introduction
      Local Newspapers such as
      have published incriminating articles such as:
      “EspecieInvasoraAtentaContra el Coquí”
      “Pesadilla en la Pista del Aeropuerto”
      “PlagaDeclarada e Ingnorada la Poblaciónde Iguanas”
    • Problem to Address
      Many inferences and statements have been made about the iguanas effect on the Puerto Rican ecosystems.
      Many of these statements are made without research support.
    • Problem to Address
      It is fundamental to;
      • Clarify misconceptions behind these animal’s behaviors.
      • Understand how they are impacting the Puerto Rican ecosystems
      • Consider that these animals are in a new habitat.
    • How do we Address this Issue?
      Previous work has been done on this project for three years now.
      We will be working with the iguanas distribution over the Puerto Rican mangrove ecosystems.
    • Main Question
      How are iguanas distributed over the mangrove ecosystems of Puerto Rico?
    • Hypothesis
      Iguanas are more abundant in border areas adjacent to human settlements.
    • Methodology
      We will use telemetry and population density techniques at the Torrecillas lagoon, San José lagoon, Piñones lagoon and San Juan bay.
    • Google Earth
    • Google Earth
    • Methodology- Telemetry
      Collecting of 11 iguanas.
      Attachment of radiotransmitors to iguanas.
      Return of iguanas to collection point.
      Monitoring of radiotransmitors will be done two times a week for one month.
      Once a week after month one.
      Data will be analyzed using special telemetry software.
      Maps will be created using a geographic information system software.
    • Short Term Goals
      • Make a detailed description of the iguanas distribution and create maps.
      • Learn how they move about in their habitat at different stages in their maturity.
    • Importance of this Study
      By determining the iguanas habitat and population density we can;
      • Develop future conservation and management systems.
      • Monitor population behavior; natality and mortality rates, migration, etc.
      • Provide overall insight into the behavior of these misunderstood animals.
      • Discover changes in behavior, if any, due to habitat change.
