The History of Life on Earth

With a solid understanding of biology on the small scale under our belts, it's time for the long view - for the next twelve weeks, we'll be learning how the living things that we've studied interact with and influence each other and their environments. Life is powerful, and in order to understand how living systems work, you first have to understand how they originated, developed and diversified over the past 4.5 billion years of Earth's history. Hang on to your hats as Hank tells us the epic drama that is the history of life on Earth.

Population Ecology: The Texas Mosquito Mystery

Season 1Episode 213 min

Population Ecology: The Texas Mosquito Mystery

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 they are in another. How is that in any way useful to anyone ever? Hank uses the example a of West Nile virus outbreak in Texas to show you in this episode of Crash Course: Ecology.

Human Population Growth

Season 1Episode 313 min

Human Population Growth

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 growth has happened over the past hundred and fifty years or so, and how those specifics relate to ecology.

Community Ecology: Feel the Love

Season 1Episode 413 min

Community Ecology: Feel the Love

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.

Community Ecology II: Predators

Season 1Episode 513 min

Community Ecology II: Predators

Hank gets to the more violent part of community ecology by describing predation and the many ways prey organisms have developed to avoid it.

Ecological Succession: Change is Good

Season 1Episode 613 min

Ecological Succession: Change is Good

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.

Ecosystem Ecology: Links in the Chain

Season 1Episode 713 min

Ecosystem Ecology: Links in the Chain

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 non-living things interacting in a specific place), and which basically comes down to who is eating who.

The Hydrologic and Carbon Cycles: Always Recycle!

Season 1Episode 813 min

The Hydrologic and Carbon Cycles: Always Recycle!

Hank introduces us to biogeochemical cycles by describing his two favorites: carbon and water. The hydrologic cycle describes how water moves on, above, and below the surface of the Earth, driven by energy supplied by the sun and wind. The carbon cycle does the same...

Nitrogen & Phosphorus Cycles: Always Recycle! Part 2

Season 1Episode 913 min

Nitrogen & Phosphorus Cycles: Always Recycle! Part 2

Hank describes the desperate need many organisms have for nutrients (specifically nitrogen and phosphorus) and how they go about getting them via the nitrogen and phosphorus cycles.

5 Human Impacts on the Environment

5 Human Impacts on the Environment

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.

Season 1Episode 1113 min

Pollution

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 ultimately, humans are responsible for it all.

Conservation and Restoration Ecology

Season 1Episode 1213 min

Conservation and Restoration Ecology

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 ecosystems and to cleaning up the messes that we've already made.

Family Guy follows Peter Griffin the endearingly ignorant dad, and his hilariously offbeat family of middle-class New Englanders in Quahog, RI. Lois is Peter's wife, a stay-at-home mom with no patience for her family's antics. Then there are their kids: 18-year-old Meg is an outcast at school and the Griffin family punching bag; 13-year-old Chris is a socially awkward teen who doesn't have a clue about the opposite sex; and one-year-old Stewie is a diabolically clever baby whose burgeoning sexuality is very much a work in progress. Rounding out the Griffin household is Brian the family dog and a ladies' man who is one step away from AA.
