Uniform spacing patterns in plants such as the creosote bush are most often associated with _____.

competitive interaction between individuals of the same population

As N approaches K for a certain population, which of the following is predicted by the logistic equation?

The growth rate will approach zero.

During exponential growth, a population always _______.

grows at its maximum per capita rate

Which of the following is characteristic of K-selected populations?

offspring with good chances of survival

Which pair of terms most accurately describes life history traits for a stable population of wolves?

iteroparous; K-selected

Which statements about K are correct? I) K varies among populations. Il) K varies in space. III) K varies in time. IV) K is constant for any given species.

only I, II, and III

Which of the following statements regarding the future of populations in developing countries are correct? I ) The fecundity is predicted to increase. II) Survivorship will increase. III) Overall population size will increase dramatically. IV) The number of offspring each year is predicted to remain high.

only II, III, and IV

Which of the following groups would be most likely to exhibit uniform dispersion?

red squirrels, who actively defend territories

Natural selection involves energetic trade-offs between ________.

high survival rates of offspring and the cost of parental care

Why does the 2009 U.S. population continue to grow even though the United States has essentially established a zero population growth (ZPG)?

immigration

Consider two old-growth forests: one is undisturbed while the other is being logged. In which region are species likely to experience exponential growth, and why?

Logged, because the disturbed forest affords more resources for increased specific populations to grow.

An ecologist recorded twelve white-tailed deer, Odocoileus virginianus, per square kilometer in one woodlot and twenty per square kilometer in another woodlot. What was the ecologist comparing?

density

What is the primary limiting factor that determines why no female animal can produce a very large number of very large eggs?

There are energy constraints.
