3.1.9-12.N: Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
Crash Course: Conservation and Restoration Ecology
Hank wraps up Crash Course Ecology by taking a look at the growing fields of conservation biology and restoration ecology, which use all the moves we've learned about in the past eleven weeks, and applies them to protecting ecosystems and to cleaning up the messes that we've already made.
TedEd: Why Is Biodiversity So Important?
Our planet’s diverse, thriving ecosystems may seem like permanent fixtures, but they’re actually vulnerable to collapse. Jungles can become deserts, and reefs can become lifeless rocks. What makes one ecosystem strong and another weak in the face of change? Kim Preshoff details why the answer, to a large extent, is biodiversity.
3.1.9-12.O: Evaluate the evidence for the role of group behavior on individual and species’ chances to survive and reproduce.
Crash Course: Animals Working Together
Social behavior like caring for our young, fighting off rivals, joining a pack, or even fusing together into a huge super animal like the Power Rangers, adds a whole other layer of complexity to the lives of animals out there. And it even raises questions about being, culture, and what it means to be an individual. So today, we're going to dive into the amazing ways animals interact with other animals, live a day in the life of the Portuguese Man O'War, and learn how these complex social interactions can go way beyond anything humans are capable of!
3.1.9-12.V: Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.
Amoeba Sisters: Speciation
Explore speciation with The Amoeba Sisters. This video discusses sympatric and allopatric speciation and covers several types of isolation types including behavioral, temporal, and habitat isolations.
Bozeman Science: Speciation
Paul Andersen explains how reproductive isolation can eventually lead to speciation. Three main barriers to gene flow are included: geographic, pre-zygotic and post-zygotic. Both allopatric and sympatric speciation are discussed. A brief discussing of polyploidy and punctuated equilibrium are also included.
Crash Course: Speciation
How can you tell two species apart? It’s not always simple. In this episode of Crash Course Biology, we’ll learn about speciation—a process that can happen over millions of years, or within a single generation. Along the way, we’ll discover how a single species can split into two and how a reptile from New Zealand continues to stump scientists.
