Ch 17: Environmental Ecology

About This Chapter

Here we provide you with lessons to enhance your knowledge of environmental ecology. Get information about the effect humans have on decreasing species populations and on ecosystems.

Environmental Ecology - Chapter Summary

Our experts have put together a set of lessons to prepare you for testing on environmental ecology. Get familiar with human-created species endangerment and extinction, biology lab procedures, and more. The lessons provide information on:

  • Pollution and destruction of the habitat
  • Declining biological diversity, deforestation and desertification
  • Over-exploitation
  • Land conservation
  • Partitioning of resources
  • Predicting changes in the environment

These lively text and video lessons are brief, with videos averaging 5-10 minutes in length. Each has a short quiz for self-assessment. Log in from your mobile device whenever you have a few minutes, to complete your next lesson and make progress on your studies.

Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction

1. Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction

In this lesson you will learn about two ways humans contribute to species extinction. We break up habitats by building roads and clearing land, and we pollute both land and water. You will also learn about the specific terms used to describe the processes, habitat fragmentation and anthropogenic pollution.

Deforestation, Desertification & Declining Biological Diversity

2. 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.

Over-Exploitation: How Humans Affect Ecosystems By Decreasing Species Populations

3. Over-Exploitation: How Humans Affect Ecosystems By Decreasing Species Populations

In this lesson, you'll learn how humans overexploit or overharvest species. You will discover the primary way in which humans are responsible for overfishing. You will also learn about how this negatively impacts ecosystems.

Land Conservation: Preserving and Restoring Ecosystems

4. Land Conservation: Preserving and Restoring Ecosystems

Humans have degraded a large portion of natural land. The field of land conservation has become popular as a way to fix this problem. Land conservation attempts to combat land degradation through preservation, restoration, remediation, and mitigation.

Resource Partitioning: Definition, Theory & Examples

5. Resource Partitioning: Definition, Theory & Examples

If you've ever wondered how so many similar species can share the same niche, resource partitioning may be the answer. Learn how partitioning resources allows organisms to specialize and outcompete their rivals.

Predicting Environmental Changes: Biology Lab

6. Predicting Environmental Changes: Biology Lab

Imagine a world that's too hot for many species, including humans. Unfortunately, this is our trajectory based on global warming. Today, we're going to look at how we can measure the changes in ocean acidification that result from global warming and the implications for ocean life.
