Chapter 6 Lesson 2 WSQ

NATURE | The Wolf That Changed America | Wolf Expert | PBS

In this Web-exclusive video, wolf expert Doug Smith discusses the Yellowstone Wolf Project. Started in 1994, the Wolf Project has taken advantage of the visibility of Yellowstone's wolves to explore wolf population dynamics. Of particular interest is how wolves interact with prey and scavenger populations in the park. Smith hopes that Wolf Project research can help replace common misconceptions about wolves with factual information.

Species Interactions

Learn about predator-prey relationships, interspecific competition, infraspecific competition, competitive exclusion principle, resource partitioning and symbiosis (mutualism, commensalism and parasitism) in this video!

Skin & Bones - Big Idea: Resource Partitioning

Woodpeckers are a good example of resource partitioning: they share physical similarities but have specialized adaptations to let them coexist in a forest without competing for the same food.

Community Ecology: Feel the Love - Crash Course Ecology #4

Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous, so a lot of interactions are actually about side-stepping direct competition and instead finding ways to divvy up resources to let species get along.
