Question

6. (6 points, 60 points cumulative) Which (one or more) of the following would be considered reasonable approaches to testing the hypothesis of density-dependent regulation in a real population? Measure seasonal changes in population size and determine their relationship to climate Experimentally manipulate population density and observe differences between populations in birth and death rates. Determine that reproductive success increases with population density at low population sizes Plot the population size in one year as a function of the previous year to determine that the slope exceeds 1.0. Plot the change in population size from one year to then next as a function of population size and determine that the slope is negative.

Explanation / Answer

5-plot the change in population size in one year to then next as a fraction of population size and determine slope is negetive

This is because the density dependent process occours when population growth rates are regulated by density of a population.this factors are biological in nature like predation,inter and intra specific competition and dfferent diseases caused by parasites.
