Lecture 5: Age-Structured Populations
S03-
so far, we have assumed that all individuals are the same.
When you think about age structure, you consider that not ALL
individuals have the same capabilities.
Childhood is the period where organisms are collecting resources, time
of accumulation and producing a body that can reproduce. All organism
have a period of accumulation
Number of individuals decreases as we move onto higher age groups.
Through out age groups, number of individuals decrease, and biological
functions change as well.
Men are ignored in these age structures, because they do not produce
babies.
S6-
different species have different survivorship curves ( some have constant
deaths through life, and some have higher death rate at the end of life)
If death is constant through life, it is exponential decay (type 2)
Humans are type 1- , and insects and clams and oysters are type 3, where
they have a lot of babies, but those babies die soon too.
S7-
-human curves are complex
- has a steep drop in the beginning infant mortality
- senescence drop

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
