Crash Course Ecology #5: Community Ecology Ii: Predators

A complete study of population ecology is covered by this worksheet. Biology or ecology learners answer questions and interpret population graphs. This can be used as the intended guided notes worksheet or assigned as homework.

Relive the birth of ecology and its different branches. The narrator of the 37th video lesson in a History of Sciences series explains the systems nature of ecology. He then explores the major advances of ecology from a historical...

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,...

Hank wraps up the Crash Course on ecology by taking a look at the growing fields of conservation biology and restoration ecology, which use all the kung fu moves we've learned about in the past eleven weeks and apply them to protecting...

Hank talks about the last major way humans are impacting the environment in this penultimate episode of Crash Course Ecology. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine distruptors - and...

In the world of ecology, the only constant is change - but change can be good. Today Hank explains ecological succession and how ecological communities change over time to become beautiful, biodiverse mosaics. [10:02]

Hank brings us to the next level of ecological study with ecosystem ecology, which looks at how energy, nutrients, and materials are getting shuffled around within an ecosystem (a collection of living and nonliving things interacting in...

Population ecology is the study of groups within a species that interact mostly with each other, and it examines how they live together in one geographic area to understand why these populations are different in one time and place than...

Hank gives the run down on the top five ways humans are negatively impacting the environment and having detrimental effects on the valuable ecosystem services which a healthy biosphere provides. [10:38]

If being alive on Earth were a contest, humans would win it hands down. We're like the Michael Phelps of being alive, but with 250,000 times more gold medals. Today Hank is here to tell us the specifics of why and how human population...
