Responsible:
Rita Yolanda Benavides Ruíz.

Participant Institutions:
Organización Vida Silvestre, A.C. and
Wildlife Preservation Trust International.

Starting date: January 1st, 1999.

Finish date: December 30, 2001.

Objectives:

1- To create a database with biological and ecological information of the reptile and amphibian species from the islands of the Loreto Bay National Park.

2- To determine the distribution of the species within the study area.

3- To generate distribution maps for the islands of the Loreto Bay National Park.

4- To detect behavioral patterns of the species being studied in relation to environmental parameters to be used in future ecological proposals.

5- To evaluate population density, age structure, born rate, mortality, sex proportion and reproductive patterns of endangered reptiles.

6- To evaluate habitat quality of reptile species.

7- To evaluate Habitat and Population Viability (HPVA) by using the Montecarlo Vortex simulation program of IUCN.

A database with biological and ecological information of the reptile and amphibian species from the islands of the Loreto Bay National Park will be created.

The information will include the distribution of all reptile and amphibian species of the study area, its behavioral patterns in relation to environmental parameters, its population densities, and age structure, born rate, mortality, sex proportions and reproductive aspects of endangered reptiles.

Also, the quality of habitat will be evaluated, plus their Population and Habitat Viability (PHVA) by means of the Montecarlo Vortex simulation program of the IUCN.
