Wed 29 Nov 2006: 6.30pm - Nest fidelity & Conservation of Bintan's Turtles

Category : marine

IOSEA Year of the Turtle Seminar
Wednesday 29th November 2006: 6.30pm

Multi-Purpose Hall, Pierce Road (see map below)
National Biodiversity Reference Centre
National Parks Board

I: "There's No Place Like Home: Investigating Nest Site Fidelity in Leatherback Sea Turtles (Dermochelys coriacea)."

II: "Bintan Resorts Turtle Conservation Initiative: identification of issues and preliminary results."

Host: Jeffrey Low

Talk 1: "There's No Place Like Home: Investigating Nest Site Fidelity in Leatherback Sea Turtles (Dermochelys coriacea)"

By Eric Nordmoe
Associate Professor, Kalamazoo College, Kalamazoo, Michigan, USA
Visiting Scientist, National Institute of Education/Nanyang Technological University, Singapore

About the talk - Do nesting leatherback sea turtles have a favourite spot on the beach? While there is general consensus that a female leatherback typically returns to nest at her natal beach, there is less certainty about whether she displays fidelity to a specific location on the beach. As leatherback populations in many areas of Asia are declining, the answer to this question may have important implications for sea turtle conservation methods. Using individual nest site selection data collected over 13 seasons at a nesting beach in Central America, I will discuss applied statistical modeling work investigating whether leatherbacks do indeed exhibit "nest site fidelity," the tendency to repeatedly nest at or near the same location on their nesting beach. Possible implications for conservation efforts in Asia will be considered.

About the speaker - Eric Nordmoe is an Associate Professor of Statistics at Kalamazoo College in Michigan. After completing his bachelorŐs degree in economics at the University of Chicago in 1981, he worked in the market research industry for seven years. He returned to academics and completed at PhD in statistics at Northwestern University in 1993. He was a lecturer in Singapore with the department of economics and statistics at NUS from 1993 to 1996.

Since 1996, he has been with Kalamazoo College in the US teaching introductory and advanced statistics courses and carrying out research in statistics education and applications. In 2002, he began collaborating with a student and a biologist colleague studying leatherback sea turtles nesting in Central America. He was delighted to find that his experience developing models to study brand loyalty in market research applied directly to the problem of investigating site fidelity in sea turtles.

Since 2002, he has been actively involved in the application of statistical models to the analysis of sea turtle nesting data. He has continued this work during his sabbatical year 2006 as a visiting scientist with NIE/NTU with the immensely valuable support of his host, Professor CH Diong.

Talk 2: "Bintan Resorts Turtle Conservation Initiative: identification of issues and preliminary results"

By Ranan Samanya
Senior Manager, Environmental and Health Division, PT. Bintan Resorts
Cakrawala

About the talk - An effort to bring back the good old days of the turtles in northen Bintan Island, Indonesia, was initiated by Bintan Resorts back in 2004.

Potential landing sites were determined, and a hatchery was set-up. Several issues encountred during the course of time were identified, and the paths being taken to overcome them are discussed. Preliminary results of the three years work in turtle survey and hatchlings releases are also explained.

About the speaker - Ranan Samanya finished his bachelor's degree in freshwater biology from Satya Wacana Christian University, Salatiga, Indonesia in 1989.

After completing his MSc. in marine ecology from Vrije Universiteit Brussel, Belgium, in 1991, he joined the Belgian Institute of Nature Conservation, where studies were done to enhance the environmental condition of the Scheldt Estuary.

In 1997 he returned to Indonesia and worked for several geothermal and mining companies to mitigate environmental issues in Java, Bali, and Sumbawa islands. He has been with Bintan Resorts since 2001.

The IOSEA Year of the Turtle Committe, Singapore is a partnership between several government bodies, university institutions and non-governmental organisations in Singapore: NIE/NTU, Underwater World, BWV, WildSingapore, AVA, NParks, NSS and NUS RMBR.
