  • Description
  • Outcome
  • Certification
  • The free online course Ecology Studies – Conservation Biology and Biodiversity provides detailed information on the current biodiversity crisis, the importance of biodiversity to human life and the use of conservation preserves and legislative frameworks for biodiversity protection. The course begins by introducing you to biodiversity and how it exists at multiple levels of organization and is measured in different ways. These measurements include numbers of species, genetic diversity, chemical diversity, and ecosystem diversity. The five mass extinctions of prehistory are explained along with the most recent extinctions recorded in written history and how they are the basis for one method of estimating contemporary extinction rates. Next, you will learn how humans use many compounds as medicines that were first discovered or derived from living organisms. You will learn how the loss of biodiversity threatens ecosystem services that support human agriculture such as: pollination, nutrient cycling, pest control, and soil development and maintenance. You will also learn about the core threats to biodiversity including human population growth and unsustainable resource use, and how habitat loss occurs through deforestation, damming of rivers, and other human activities. Finally, you are introduced to the methods of biodiversity conservation, such as the optimal design of preserves and the limitations imposed by political and economic forces. You will also gain an understanding of how legislation within individual countries protects species and how agreements on global warming have had limited success. The course will be of great interest to students or professionals who want to develop a career in various aspects of biodiversity and ecosystem conservation or for those who simply want to learn more about the biodiversity crisis, how to preserve and conserve current biodiversity levels and how human activities are the core threat to the planet's ecosystems.

  • After completing this course you will be able to:
    - Define biodiversity;
    - Explain biodiversity as the equilibrium of naturally fluctuating rates of extinction and speciation;
    - Identify historical causes of high extinction rates in Earth’s history;
    - Explain chemical diversity benefits to humans;
    - Identify biodiversity components that support human agriculture;
    - Define ecosystem services;
    - Identify significant threats to biodiversity;
    - Explain the effects of habitat loss, exotic species, and hunting on biodiversity;
    - Identify the early and predicted effects of climate change on biodiversity;
    - Identify new technologies for describing biodiversity;
    - Explain the legislative framework for conservation;
    - Explain the principles and challenges of conservation preserve design;
    - Identify examples of the effects of habitat restoration;
    - Discuss the role of zoos in biodiversity conservation.

Topics List ( 5 )
Module 1: Biodiversity Crisis
This module explains how biodiversity exists at multiple levels and is measured in different ways. It also explains how these measurements include numbers of species, genetic diversity, chemical diversity, and ecosystem diversity. The module also explains the five mass extinctions observable in the fossil record, and how recent extinctions recorded in written history and are used as one method for estimating contemporary extinction rates. The other method utilises measures of habitat loss and species-area relationships.

Module 2: The Importance of Biodiversity
In this module the main focus is on how humans use many compounds that were first discovered or derived from living organisms as medicines: secondary plant compounds, animal toxins, and antibiotics produced by bacteria and fungi. How crop diversity is a requirement for food security, and it is being lost, and how biodiversity may provide important psychological benefits to humanity. The core threats to biodiversity are also covered, such as human population growth and unsustainable resource use. How habitat loss occurs through deforestation, damming of rivers, and other activities and how over-harvesting is a threat particularly to aquatic species. The module also explains how climate change is forcing species range changes that may lead to extinction. It is also affecting adaptations to the timing of resource availability that negatively affects species in seasonal environments.

Module 3: Preserving Biodiversity
Module 3 covers the legislative framework for biodiversity protection and the cataloguing of the planet’s biodiversity using methods such as DNA barcoding and information processing. The module also focuses on how conservation preserves are a major tool in biodiversity protection and how the science of island biogeography has informed the optimal design of preserves. The reintroduction of keystone species to restore ecosystems to previous biodiversity levels and the more active role zoos are taking in conservation are also covered.
