Map of organism.
The organism that I found interesting was the tree frog. Tree frogs mostly live in trees all around the world and their sizes range from 1 inch to 4 inches. They will either have pads or claws on their fingers and toes to help them climb. Tree frogs have a special type of skin that secretes glycerol to help them keep warm. During summer and spring time, the male and female tree frog will mate and build a nest to store the eggs. The female can lay from 200 to 2000 eggs in the water, and water flow will help to disperse. Of the many eggs laid, only 1 or 2 will mature to an adult frog because the tadpoles eat each other to survive.

From my site, the tree frogs all lived in one single population. The tree frogs lived relatively clumped up in one area and close to one another, so the mates could be found easily. They were located near the swamp because there were enough trees and moisture for them to survive. The trees provided an established habitat, and the swamp provided food and environment to reproduce. This seems more of a source population, because there is less competition for resources and habitat. The population will exhibit stable growth because the lack of competition from others, and the quality of their habitat is decent. The offspring of the population are mostly in the water waiting for maturity. Immigrants are not likely, but if there were it should be from the stream leading up to the swamp.
A) Given that the average number of offspring per female is 2.
In 5 cycles, there should be about 10 offspring.
In 20 cycles, there should be about 40 offspring.
Yes, because the number of offspring is increasing.
B) One model that relates can be the Diamondback Terrapin experiment from lecture. Diamondback Terrapin turtles have a long incubation period and their overall survivorship is only about 60%. Although the turtles may lay plenty of eggs, only a few or maybe even none survive. Just like the tree frogs at my site, the survivorship of the tadpoles is very low as they compete for survival.
Another model that relates can be the density-dependent factor. One example of density-dependent factors would be the trees. Trees that have limited light would be affected in growth. The tree frogs at my site need space, if space was limited then the ability to reproduce and survivorship of tadpoles would decrease.
