Tests of Population Census and Animal-Habitat Models for Conservation

EPA Grant Number: U915343
Title: Tests of Population Census and Animal-Habitat Models for Conservation
Investigators: Airame, Satie
Institution: University of Chicago
EPA Project Officer: Broadway, Virginia
Project Period: January 1, 1998 through December 31, 2000
Project Amount: $44,345
RFA: STAR Graduate Fellowships (1998)
Research Category: Academic Fellowships , Ecological Indicators/Assessment/Restoration , Fellowship - Ecology and Ecosystems

Description:

Objective:

The main objectives of this research project are to: (1) determine the level of detail necessary to understand and predict fluctuations in amphibian species' occurrences and abundances; and (2) develop population projection models from increasingly detailed data (population censuses, animal-habitat relationships, and population demography) for amphibian species in primary forest and agricultural land on the island of Borneo.

Approach:

I will compare different levels of resolution across studies of species' occurrence and abundance from: (1) population censuses; (2) habitat use and availability; and (3) habitat-specific demography to determine the contribution of each study to understanding and prediction of population dynamics. I will use amphibian census data from historical records and current surveys to project short- and long-term population trends. I will develop amphibian-habitat models based on empirical data from populations in primary forests, where the abundance and quality of habitat and the behavior of amphibians are not altered by human activities. I will test amphibian-habitat model predictions with empirical data from populations in agricultural areas. Demographic data from representative species will be used to determine whether or not predictions from population censuses and the amphibian-habitat models correlate with species' performance.

The results of this research project will be used to determine the correlation between species' performance and predictions from census and amphibian-habitat models.
