Research Data

We are currently processing data from our first three field season at the Tiputini Biodiversity Station located in northeastern Ecuador.

  • Over 1000 specimens have been captured, georeferenced, processed, and released.
  • Over 80 species identified, with more to be confirmed.
  • Over 60 hours of frog calls recorded, totaling more than 40 confirmed species.

We have constructed a relational database which will be interfaced with GIS for analysis and web viewing. This data will also be available for others to utilize in the efforts of conservation.

Our goal for this project is to create a comprehensive and dynamic, user-friendly environment to graphically display amphibian conservation research. We plan to incorporate historical data and data from others who wish to contribute in the future. Please contact us if you wish to help.
