Population Dynamics

Episode 12

In the opening segment, Patrice looks at population and the limiting factors that can impact it. Next, she visits with Dave and they explore how a variety of factors can impact porcupine populations. The third segment takes an up-close look at the white-tailed deer. And finally, Von and Daniel visit with Professor Peter Pekins from the University of New Hampshire to learn about how he is helping to control deer numbers.

Population Dynamics

Population is the number of individuals of a particular species in an area. Animal and plant populations depend on many things for survival. Limiting factors like the availability of food, water and shelter can impact an organism’s population.
In nature, populations of animals and plants are linked together like a puzzle. The pieces of the plant and animal puzzle depend on each other to form a complete picture. If something is wrong with any of the pieces, it affects the whole puzzle.

Other Concepts

… when one population in an ecosystem changes, populations of other organisms can also change.

… people can have an enormous impact on plant and animal populations.
