Indicate what is correct and incorrect about this statement: If lizards want to survive during climate change, they can evolve new life-history traits.

Explain why biologists want to maintain (a) 'habitat corridors' that connect populations in a metapopulation, and (b) unoccupied habitat that is appropriate for the species in question.

During exponential growth, a population alwaysa. has a constant per capita population growth rate.b. quickly reaches its carrying capacity.c. cycles through time.d. loses some individuals to emigration.

Skyrocketing growth of the human population appears to be mainly a result ofa. a drop in death rate due to sanitation and health care.b. better nutrition boosting the birth rate.c. the concentration of humans in cities.d. social changes that make it desirable to have more children.

The current carrying capacity of Earth for the human population may have been inflated by .a. demographic momentum;b. the tendency for women to want to control family size;c. an artificially low number of density-independent factors;d. our use of fossil fuels;e. recent population crashes

Which of the following statements about human populations in industrialized countries is incorrect?a. Birth rates and death rates are high.b. Average family size is relatively small.c. The population has undergone the demographic transition.d. The survivorship curve is Type I.

According to data on ecological footprints,a. the carrying capacity of the world is 10 billion.b. Earth's resources are sufficient to sustain future generations at current levels of consumption.c. the ecological footprint of individuals in the United States is more than twice the world average.d. nations with the largest ecological footprints have the fastest population growth rates.
