Taiga Biome | Biology

Jessica Pamment of DePaul University explains all about taiga biomes, the largest terrestrial biomes on Earth. Taigas are also known as coniferous forests. They are found in the sub-Arctic regions of North America. There is moderate precipitation (30-70cm/year). Temperatures are cold or cool year-round (-30°C in winter and 20°C in summer). They have low biodiversity.

Ecosystem Ecology: Links in the Chain - Crash Course Ecology #7

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 a specific place), and which basically comes down to who is eating who.

Symbiosis: Mutualism, Commensalism, and Parasitism

A big thanks to all current and future patrons who are helping fund this science communication outreach via Patreon:

Symbiosis is close and often long-term interaction between different biological species.

The definition of symbiosis is controversial among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to all types of persistent biological interactions (i.e. mutualistic, commensalistic, or parasitic).

In this video we show how you can simply visualize all three.

The Coniferous Forest Biome Explained

A big thanks to all current and future patrons who are helping fund this science communication outreach via Patreon:

I re-uploaded this because of a bad video encoding by YouTube. I honestly don't know why it works for half of you and the other half have problems.

This week I wanted to do a simple, yet important short about a biome we haven't done before - the coniferous forest biome. A lot of people skip this one when they teach biomes in schools, but it's an important (and interesting) one. You can read more about it in our in-depth article on it here:

The History of Life on Earth - Crash Course Ecology #1

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.

Vascular Plants = Winning! - Crash Course Biology #37

Hank introduces us to one of the most diverse and important families in the tree of life - the vascular plants. These plants have found tremendous success and the their secret is also their defining trait: conductive tissues that can take food and water from one part of a plant to another part. Though it sounds simple, the ability to move nutrients and water from one part of an organism to another was a evolutionary breakthrough for vascular plants, allowing them to grow exponentially larger, store food for lean times, and develop features that allowed them to spread farther and faster. Plants dominated the earth long before animals even showed up, and even today hold the world records for the largest, most massive, and oldest organisms on the planet.

Why No Giant Mammals?

Ecological Succession-Primary and Secondary

Ecological Succession occurs when an ecosystem has a disturbance and must regrow. Succession is all about change.
There are two main types of succession, primary and secondary.
Primary occurs when an area has been almost destroyed and little life or soil remains.
Pioneer species are the first plants to regrow.
Secondary succession occurs where you have a disturbance but the soil remains.

Climate Science: Crash Course History of Science #45

Scientists tend to be careful and resistant to big claims. So evidence for the possible end of the living world took a while to be seen as such. In this episode of Crash Course History of Science, Hank talks to us about where Climate Science started and how it works today.
