Chapter 25.4, Problem 44CQ

Summary Introduction

To determine:

The factors that cause the loss of genetic variation in the establishment of a captive population.

Introduction:

The amphibians live on the ground, but they lay their eggs in the aquatic environment. The amphibians reproduce by external fertilization. The eggs are fertilized and hatch into tadpoles. The salamanders and newts have a slender body and a long tail. The salamanders more live in water and less in land, whereas, the newts live in the land more than water.

Summary Introduction

To determine:

The ways by which the loss of such variation can be prevented.

Introduction:

The endangered species is an important part of the ecosystems. The increasing human population and exploitation of resources have resulted in the damaging of the ecosystems. The ecosystem conservation is included in the conservation biology. The national parks are the protected areas for the animals and plant species so that they can flourish properly and the endangered species can be saved.

Summary Introduction

To determine:

The procedures that should be instituted to ensure the long-term maintenance of as much variation as possible.
