Ch 36: Overview of Biodiversity

About This Chapter

Utilize this overview of biodiversity to increase your understanding of desertification, endangered species, and landscape ecology. The lessons in this chapter will help you get ready to take an exam or engage in a class discussion.

Overview of Biodiversity - Chapter Summary

Included in this chapter on biodiversity is landscape ecology and causes of declining biological diversity. You will also learn how population size impacts the gene pool. After completing the chapter, you should be able to:

  • Explain why biodiversity is important for maintaining healthy ecosystems
  • Discuss the effect of inbreeding on the gene pool
  • Recall how deforestation can result in a decline in biological diversity
  • Interpret the principles of conservation biology
  • Describe the differences between endangered and threatened species
  • Discuss issues biologists and ecologists face when establishing biodiversity hot spots

Our instructors assist you with quickly grasping concepts related to biodiversity. A brief quiz is available for each lesson to test your understanding of topics covered, and the quizzes can be printed for use as a study tool. If you get a question wrong on the quiz, you can review that topic again by clicking on the link provided.

What is Biodiversity? - Definition and Relation to Ecosystem Stability

1. What is Biodiversity? - Definition and Relation to Ecosystem Stability

Imagine making a list of all of the species you have ever heard of; it would be an enormous list! There are many different species on this planet. This lesson will explore the diversity of species, as well as the different types of diversity and how diversity of life is essential for maintaining healthy ecosystems.

Genetic Implications of the Gene Pool

2. Genetic Implications of the Gene Pool

This lesson explores the relationship between the gene pool, genetic diversity, as well as factors such as population size and inbreeding and their effect on the gene pool.

Deforestation, Desertification & Declining Biological Diversity

3. Deforestation, Desertification & Declining Biological Diversity

When trees are lost due to deforestation, the result can be a drier climate and desertification or the transformation of the once fertile land to desert. Learn how deforestation and desertification can lead to a decline in biological diversity.

What Is Conservation Biology? - Definition & Principles

4. What Is Conservation Biology? - Definition & Principles

Conservation biology aims to reduce the human impact on the environment by looking for the causes and possible solutions to these problems. In this lesson, you'll learn about conservation biology and the different types of conservation.

Differences Between Endangered Species and Threatened Species

5. Differences Between Endangered Species and Threatened Species

In this lesson you'll learn about two terms that describe species with very low population numbers: threatened and endangered. You'll discover why species numbers decline and how we can keep the species that are threatened or endangered from going extinct.

Landscape Ecology: Establishing Protected Areas

6. Landscape Ecology: Establishing Protected Areas

This lesson focuses on some of the concerns biologists and ecologists face when identifying and establishing biodiversity hot spots and nature reserves. Take the short quiz at the end to test your understanding.
