Imagine a prairie inhabited by populations of several different species of snakes: prairie kingsnakes, black racers, fox snakes, garter snakes, and ribbon snakes. You manage the prairie primarily by conducting regular controlled burns. You are one day given the opportunity to introduce a herd of bison to the prairie. Would the environmental changes associated with the introduction of grazing be expected to effect each population of snake the same way?

You do a population study of woodpeckers in two different forests. The results from the two forests are:
Forest A
-
You find that 50% of trees are suitable for excavating nest cavities
-
On average 5 young are fledged per nest
-
Estimated available forage biomass = 5 kg/ha
Forest B
-
You find that 50% of trees are suitable for excavating nest cavities
-
On average 3 young are fledged per nest
-
Estimated available forage biomass = 6 kg/ha
Which forest is the higher quality woodpecker habitat?

What's that? You want another question about a hypothetical population of woodpeckers? Well, if you insist.
Say you are studying a species of woodpeckers in a forest, and you are interesting in learning about nesting habitat.
You do surveys during the nesting season, find as many woodpecker nests as possible, and measure the height of all the trees you find that woodpeckers have used to make nests in.
You also measure the heights of a large number number of randomly selected trees in the forest - trees that were available in the forest, but not used for nesting.
You report that the overall height of available trees in the forest ranges from 4 - 10m, and the heights of trees that woodpeckers used for nesting was 6 - 8m. What type of information are you reporting?

Below are the results of a sensitivity analysis presenting the analytical elasticity for annual survival of a species with 5 different age classes:
Based on these results, is the population more sensitive to changes in the survival rates of young age classes, or older age classes?

Within a sub-population, we observe that:
Reproductive rates outpace mortality and the population is near environmental carrying capacity.
Surplus individuals regularly disperse from the subpopulation and a portion of them successfully settle and integrate into other subpopulation.
Is this populations a source population, a sink population, or neither?
