Population Ecology

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple-choice, graph interpretation, and essay-analysis questions, 73 of them in all. Topics range from...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

For AP biology or ecology classes, here is a worksheet that explores population growth. Carrying capacity, limiting factors, and k-strategies are dealt with using short-answer questions. 

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases...

While 80 percent of people with West Nile Virus show no symptoms, in severe cases, it causes death by infecting the membranes around the spinal cord and brain. The video starts by making population ecology relevant. It includes density...

With a human population of 7.6 billion and counting, how do we tackle the population problem? Examine the data using a video from an extensive science playlist. The resource explains why the human population began to increase rapidly,...

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

In the following video, Evan Seimann, PhD, defines key terms and concepts of ecology, basic characteristics of populations, population age structures and densities, and explains the dynamics of growth models within a population. [22:59]

Paul Andersen explains how population ecology studies the density, distribution, size, sex ration, and age structure of populations. Intrinsic growth rate and exponential growth calculations are included along with a discussion of...

The carrying capacity of an environment varies based on the organisms that live there. Using a virtual lab simulation, scholars test two protists living in their own environments and a third environment where both protists live....
