Special | 14m 49s

Patrice looks at how all organisms have their own role or niche in their environment. Next, Patrice and Dave look at the niche of the pileated woodpecker. Then we take an up-close look at coral reefs and the niches they fill in the ocean. Finally, Von and Marshall spend the day with conservation officer Joe Giarrusso and learn how he's trying to control the impact of beavers in urban areas.
