Why when lemming populations decline do populations of Arctic foxes also decrease?
One of the Arctic Foxes' main sources of food is the Lemming. When there are abundant lemmings the Fox has food to raise large litters and the population of Foxes increases. Similarly the numbers of Foxes that can be fed decreases when the lemming population declines because there is less food for the Foxes.
Basically the population of any animal is controlled by its food supply.
Changes in genetic equilibrium can lead to speciation over longer periods of time, typically spanning thousands to millions of years. Rapid bursts of speciation, known as adaptive radiations, can occur in certain circumstances such as when a population undergoes rapid environmental changes, leading to the rise of multiple new species in a relatively short time span.

What type of population statistics can be gathered with collecting data?
The National Census Bureau is responsible for maintaining the census database. A population census can take over a year to complete. The census statistics will show the current population of the town or city and how it has grown or not over the past ten years.
Researchers are using a procedure known as simple random sampling. This involves selecting individuals at random, where every individual has an equal chance of being selected, to ensure the sample is representative of the population.

How does the rate of population growth influence the level of GDP per person?
A faster population growth means that on average, there are more young people who cannot yet make a significant contribution to the economy. Since GDP per person doesn't take into account whether someone is of age to work yet, a high population growth means that there are more people to divide the GDP among, so on average it will be lower.
Another reason that GDP per person is lower in high population growth countries is that people tend to have large families in agricultural economies, where you can put children to work to generate some income at an early age. These types of economies do not have the same capacity for growth as industrial economies, where technology can be more effectively used to boost output. Also, when the economy is not as developed and there are not good social benefits, which is typically the case in Third World countries, people have more children as a way to ensure their old age, which increases the growth rate and skews the labor market towards less skilled jobs

Is subset or some part of a larger population?
In mathematics a subset is any part of a set including the entire set or the empty set (ie, the set with no elements). Some of th people doing statistics on populations might be unwilling to include the empty set as a subset of a population.
The two most important weather factors in determining the plant and animal populations that can exist in an area are climate and rainfall. These factors will determine what food sources will be available in the area as well.
