Find out what you know about population ecology by taking this interactive post test.

Practice exercise on population ecology.

College-level online course highlighting the fundamentals of ecology. Course topics include coevolution of the biosphere, geosphere, atmosphere, and hydrosphere; photosynthesis and respiration; and the carbon, nitrogen, and water cycles....

Students control the environments in four different scenarios to discover how any changes might affect populations. The different simulations include microorganisms, rabbits, foxes, and other organisms.

Students review the study of living things and make connections back to Earth's systems. This unit focuses on how various species, grouped in populations and communities, work with the nonliving things around them to ensure survival.

Do you know the difference between population genetics and quantitative genetics? This webpage examines both population genetics which concentrates on frequencies of alleles and genotypes and quantitative genetics which deals with the...

A webpage giving an overview of ecology. Learn about the biotic and abiotic factors that make up an ecosystem as well as the different levels of ecology.

[Free Registration/Login may be required to access all resource tools.] Ecosystems are organized into several different levels, and they can be studied at any one of the various levels of organization. Learn more about levels of...

Learn about how ecology is simply the study of how and why organisms interact with their environments.

This article describes tools ecologists use to describe the present state of a population and predict its future growth.

Read and understand the concept of ecological population counts and sizes. Hover the mouse over questions to reveal the answers as you sharpen your skills.

Take this five-question, self-checking quiz on population dynamics in ecology.

This StudyCards stack enables students to review the vocabulary used in studying ecology.

In this biology field lab exercise, students conduct a stationary population study of goldenrod galls. They examine a host of factors including goldenrod plant density, goldenrod gall density, gall height, gall mass, larval exit hole...

In this three-part activity, students apply linear, exponential, and rational functions to explore past and projected U.S. population growth, carbon footprint trend, ecological overshoot, and effectiveness of hypothetical carbon dioxide...

The computer program's simulation of a Sonoran desert community should ultimately strengthen the student's comprehension of what is required for a natural ecosystem to sustain itself (remain in balance). This computer simulation program...

The Earth's population is soaring, but its resources are finite. Can we provide food, water, energy? Watch a slideshow on our planet's future, and take a quiz to measure your impact on the Earth.

Learn what happens to different populations of organisms as their ecosystem changes. Design your own experiment and make your own guesses with what the result will be with this virtual ecosystem. Also experiment with producer/consumer...

General info from the University of California on the the physical characteristics and population ecology of roundworms.

Build your own ecosystem, and explore the effects of these interrelationships.

A field experience where students undergo an exploration in a natural environment. They are introduced to the concepts of species, population, community, ecosystem, niche, and biosphere.

[Free Registration/Login Required] This flipchart features the levels of ecological organization. Students can move objects to reveal decryptions and answers! An Activote quiz accompanies this flipchart, but may have to be downloaded and...

Adjust the number of fish in a lake to be tagged and the number of fish to be recaptured. Use the number of tagged fish in the catch to estimate the number of fish in the lake. (Free usage is limited to five minutes per day.)

This collection of three learning modules looks at issues related to resource consumption. It examines theories about how population size affects consumption, the changing patterns of energy consumption, and ways to minimize consumption....
