1. Module 8

Introduction

Module 8—Populations, Individuals, and Gene Pools

 

Introduction

 

In this module you will be introduced to the gene pool, and you will learn how to quantify its makeup, determine whether it is changing, and determine what factors led to this change. You will apply your knowledge to determine what factors and conditions in a population change the gene pool and to analyze the effects of these factors.

 

Next, you will look at how the interactions and symbiotic relationships between organisms affect the structure of populations and communities. You will examine defence mechanisms that organisms use to survive predation and competition. You will study the concept of succession and how the species that make up communities change over time. You will apply your knowledge to discussing the relationships that exist between species and ecosystems and the effects these interactions have on population changes.

 

You will examine the factors that contribute to growth, and you will learn how growth within populations is measured. As part of your studies, you will learn about the two major types of growth patterns and the two reproductive strategies used by organisms for maximizing population growth. Finally, you will learn how biologists measure, interpret, and analyze the changes in populations over time.

 

This module relies on prior knowledge of genetics, ecosystems, and, to some degree, evolution. If you need to review these concepts prior to starting this module, read Chapters 3, 14, and 17 in your textbook.

 

In the Biology 30 Course Introduction, several resources, including The Key and Student Notes and Problems Workbook: Biology 30, were recommended to you for additional support towards your success. Continue to use these resources as you work through Module 8.
