Document Summary
For gray squirrels- it displays age, # pups born to each female of age x, and # female pups born to each female of age x, mx. Proportions of a population in each age class. Important indicator of whether population will increase, decrease, or be stable. Life history patterns characterizes a species- record of major events related to an organisms growth, development, reproduction and survival. Life history theory- solutions are well-suited to meeting challenges and constraints of the environment, Success in the sense that populations persist over time. 1 out of a million small , billions of offspring immediate- 1 day. Tradeoffs- allocation of limited energy/resource to one function at expense of another. Number and size of offspring, number of offspring and parental investment, reproduction and survival, and reproduction and growth. More offspring produced/year the less each can be cared for, affects the parents ability to take care of each for a long time.
