Ecosystems	If we were to draw in what the K value is, I would say K value so far looks like right about here.
Ecosystems	Maybe around 140, 150 wolves that Yellowstone Park can support.
Ecosystems	Now those wolves are moving outside of the park as well.
Ecosystems	There's competition that happens then.
Ecosystems	So this is the same thing.
Ecosystems	Here is that growth of wolves.
Ecosystems	So the wolves are going to be on this side.
Ecosystems	So their population went up.
Ecosystems	They've gone down, up, down.
Ecosystems	It will probably go up.
Ecosystems	So it's just going like that.
Ecosystems	So on this side we've graphed the wolves.
Ecosystems	But let's look at what has happened to the elk population.
Ecosystems	So the elk population is going to be listed on the other side.
Ecosystems	Something like 87% of what wolves eat are elk.
Ecosystems	And so these two are linked together.
Ecosystems	They eat bison.
Ecosystems	They eat moose.
Ecosystems	They eat a lot of different things.
Ecosystems	But in general they're mostly eating elk.
Ecosystems	And so if we look at what's happened to the elk population during this time, the elk population started at around, this is in the northern area of Yellowstone Park, started around 16,000.
Ecosystems	But it steadily dropped off.
Ecosystems	Okay.
Ecosystems	So now it's down to who knows, 5,000 elk maybe in 2011.
Ecosystems	So what pressure is that going to put on wolves?
Ecosystems	Well now there's not a lot of food to eat.
Ecosystems	And so the wolf population is going to drop off.
Ecosystems	As the wolf population drops off they're going to feed on less elk.
Ecosystems	And so there's probably going to be this predator prey relationship between the two where the elk population will start to make a comeback.
Ecosystems	It will drop off like that.
Ecosystems	And then if we look at the wolf population, wolf population is going to follow that as well.
Ecosystems	And so we reach what's called an equilibrium.
Ecosystems	Now this is great for wolves.
Ecosystems	Not great if you're an elk hunter in Montana because the population has gone from 16,000 down to like 5,000.
Ecosystems	So as they move out of Yellowstone Park, as wolves move into that area that's private like I mentioned at the beginning, there get to be real human issues and impacts with that.
Ecosystems	Last thing that I want to talk about relates to humans then.
Ecosystems	So humans can have huge impacts on an ecosystem and not knowingly we can make big changes.
Ecosystems	So let me tell you the story of the whitebark pine.
Ecosystems	Whitebark pine is going to be found in Yellowstone Park.
Ecosystems	If we look at where it is, here's present day whitebark pine.
Ecosystems	So it's usually going to be found in higher areas.
Ecosystems	But basically it's a sturdy kind of a pine.
Ecosystems	It can deal with lots of snow and really cold temperatures.
Ecosystems	But they'll produce pine nuts during the year.
Ecosystems	And those pine nuts are gathered up by squirrels.
Ecosystems	So the squirrels love to grab the pine nuts.
Ecosystems	They dig and create these middens which are just like a stash of a bunch of these pine nuts.
Ecosystems	They'll feed on those during the winter.
Ecosystems	But sometimes they forget where they are.
Ecosystems	And a lot of the time those middens are, middens I think, M-I-D-D-E-N-S, are raided by grizzly bears.
Ecosystems	So grizzly bears will move up into these areas and they'll raid these middens.
Ecosystems	And so it's a big part of their food supply before they start to hibernate in the winter.
Ecosystems	And so what's happening?
Ecosystems	Well global warming, so changes to the global climate or climate change is creating warming conditions in Yellowstone Park.
Ecosystems	And this is projections of what will happen to the whitebark pine population if we just get a moderate increase in temperature.
Ecosystems	They can't deal with that.
Ecosystems	And so the whitebark pine is going to drop off.
Ecosystems	As a result of that, squirrels aren't going to have any nuts that they can actually stash.
Ecosystems	Grizzlies aren't going to have that.
Ecosystems	And so you can see that this food chain is tied to the environment.
Ecosystems	Tied into the, in this case it's going to be the overall temperature.
Ecosystems	And so human impacts are so fast, so global climate change is so fast that it forces pressure on all the species within that ecosystem and all those connections.
Ecosystems	A lot of the ones we don't even know.
Ecosystems	And so that's ecosystems.
Ecosystems	They're really delicate.
Ecosystems	They also have feedback loops that kind of maintain that equilibrium.
Ecosystems	But I hope that's helpful.

AP Bio Macromolecules - Part 2	Hello and welcome back for the second half of the macromolecule chapter.
AP Bio Macromolecules - Part 2	We're going to cover proteins and nucleic acids.
AP Bio Macromolecules - Part 2	These guys have their own kind of section here.
AP Bio Macromolecules - Part 2	I've kind of held them off because these are two of the most critical things for humans, any animal, plant, bacteria, anything alive for them to function and survive.
AP Bio Macromolecules - Part 2	Proteins especially are incredibly important because they act in so many capacities.
AP Bio Macromolecules - Part 2	Most anything with colors because of a protein.
AP Bio Macromolecules - Part 2	Many of your hormones are because of proteins.
AP Bio Macromolecules - Part 2	A lot of your structural components, what makes your bones flexible, what holds all your organs in place, the stuff that makes up your fingernails, your hair, these are all proteins.
AP Bio Macromolecules - Part 2	What does chemical reactions?
AP Bio Macromolecules - Part 2	We'll talk about enzymes later.
AP Bio Macromolecules - Part 2	All enzymes are proteins.
AP Bio Macromolecules - Part 2	So there's going to be an incredible amount of the molecules in your body.
AP Bio Macromolecules - Part 2	In some cases it can be upwards of about half of your dry body weight.
AP Bio Macromolecules - Part 2	I should say body mass here to be correct.
AP Bio Macromolecules - Part 2	It's going to ultimately come down to proteins.
AP Bio Macromolecules - Part 2	So these guys are huge.
AP Bio Macromolecules - Part 2	Which proteins you have can largely determine how well you function, if you function, if you survive.
AP Bio Macromolecules - Part 2	A lot of that is because they can be incredibly diverse owing to the fact that they are a polymer that consists of amino acid monomers.
AP Bio Macromolecules - Part 2	There are 20 different amino acid monomers.
AP Bio Macromolecules - Part 2	Each of them has a different R group.
AP Bio Macromolecules - Part 2	So there's basically several parts of an amino acid.
AP Bio Macromolecules - Part 2	They typically have a carboxylic group, carboxylic acid group, hence the acid.
AP Bio Macromolecules - Part 2	They tend to have an amine group, an NH2 group.
AP Bio Macromolecules - Part 2	An amine or an amino group.

So on this side we've graphed the wolves.

So the elk population is going to be listed on the other side.

Ecosystems

Something like 87% of what wolves eat are elk.

But it steadily dropped off.

Ecosystems

Okay.

Ecosystems

So now it's down to who knows, 5,000 elk maybe in 2011.

Ecosystems

So what pressure is that going to put on wolves?

Ecosystems

Well now there's not a lot of food to eat.

As the wolf population drops off they're going to feed on less elk.

And so there's probably going to be this predator prey relationship between the two where the elk population will start to make a comeback.

Ecosystems

It will drop off like that.

Ecosystems

And then if we look at the wolf population, wolf population is going to follow that as well.

Ecosystems

And so we reach what's called an equilibrium.

Ecosystems

Now this is great for wolves.

Ecosystems

Not great if you're an elk hunter in Montana because the population has gone from 16,000 down to like 5,000.

Ecosystems

So as they move out of Yellowstone Park, as wolves move into that area that's private like I mentioned at the beginning, there get to be real human issues and impacts with that.

Ecosystems

Last thing that I want to talk about relates to humans then.

Ecosystems

So humans can have huge impacts on an ecosystem and not knowingly we can make big changes.

They dig and create these middens which are just like a stash of a bunch of these pine nuts.

They'll feed on those during the winter.

Ecosystems

But sometimes they forget where they are.

Ecosystems

And a lot of the time those middens are, middens I think, M-I-D-D-E-N-S, are raided by grizzly bears.

Ecosystems

So grizzly bears will move up into these areas and they'll raid these middens.

Ecosystems

And so it's a big part of their food supply before they start to hibernate in the winter.

Ecosystems

And so what's happening?

Ecosystems

Well global warming, so changes to the global climate or climate change is creating warming conditions in Yellowstone Park.

Ecosystems

And this is projections of what will happen to the whitebark pine population if we just get a moderate increase in temperature.

Ecosystems

As a result of that, squirrels aren't going to have any nuts that they can actually stash.

Ecosystems

Grizzlies aren't going to have that.

Ecosystems

And so you can see that this food chain is tied to the environment.

Ecosystems

Tied into the, in this case it's going to be the overall temperature.

Ecosystems

And so human impacts are so fast, so global climate change is so fast that it forces pressure on all the species within that ecosystem and all those connections.

Ecosystems

A lot of the ones we don't even know.

Ecosystems

And so that's ecosystems.

Ecosystems

They're really delicate.

Ecosystems

They also have feedback loops that kind of maintain that equilibrium.

Ecosystems

But I hope that's helpful.
