Exam 40: Population Ecology and the Distribution of Organisms

Which of the following graphs illustrates the growth curve of a small population of rodents that has grown to reach a static carrying capacity?

Which variables define the ecological life history of a species?

Long-term studies of Belding's ground squirrels show that immigrants move nearly 2 km from where they are born and become 1-8% of the males and 0.7-6% of the females in other populations. On an evolutionary scale, why is this significant?

Often the growth cycle of one population has an effect on the cycle of another. As moose populations increase, for example, wolf populations also increase. Thus, if we are considering the logistic equation for the wolf population, dN/dt = rN , which factor accounts for the effect of the moose population?

Which of the following is the best natural example of uniform distribution?

In which of the following situations would you expect to find the largest number of K-selected individuals?

Which of the following methods would provide the most legitimate data on population density?

Which of the following graphs illustrates the population growth curve of single bacterium growing in a flask of ideal medium at optimum temperature over a 24-hour period?

What is an assumption of the logistic model of population growth?

Which of the following events might you predict to occur if the tilt of Earth's axis relative to its plane of orbit was increased to 33 1/2 degrees?

Generalized global air circulation and precipitation patterns are caused by

What is population dispersion?

Please use the following information to answer the question(s) below. In areas of permafrost, stands of black spruce are frequently observed in the landscape, whereas other tree species are noticeably absent. Often these stands are referred to as "drunken forests" because many of the black spruce are displaced from their normal vertical alignment. -A population's carrying capacity
