All right, so in this question here, we're looking at survivorship curves and what can maybe alter them.
00:09
And so you have to be reminded of the three different types of survivorship curves.
00:13
You have type one, type two, and type three.
00:15
So type one has high proportion or probability of surviving very young, and then the probability or proportion surviving drops off quickly.
00:27
An example of this is humans.
00:31
And think about that for a second, right? children typically and young people do not die.
00:36
And then when you start getting into your 60s, 70s, and 80s, you start to get higher and higher probability of death.
00:43
Then you have type 2, which has equal probability of surviving throughout their lives.
00:50
Example of this is birds.
00:52
Basically, you have the same probability of surviving when you are young as when you are old.
00:57
And then you have type three curves.
01:00
This is where you have very low probability of surviving early on, but then if you reach a particular size, you have extremely high survivability...
