Population Change Using mathematical notation we can express this relationship as follows: If N represents population size, and t represents time, then N is the change is population size and t represents the change in time, then: N/t = B-D Where B is the number of births and D is the number of deaths
Population Change We can simplify the equation and use r to represent the difference in per capita birth and death rates. N/t = rN OR dN/dt = rN If B = D then there is zero population growth (ZPG). Under ideal conditions, a population grows rapidly. Exponential population growth is said to be happening Under these conditions, we may assume the maximum growth rate for the population (rmax) to give us the following exponential growth dN/dt = rmaxN
Exponential Growth
Logistic Growth Typically, unlimited resources are rare. Population growth is therefore regulated by carrying capacity (K), which is the maximum stable population size a particular environment can support.
Logistic Growth The logistic growth equation We can modify our model of population growth to incorporate changes in growth rate as population size reaches a carrying capacity. The logistic population growth model incorporates the effect of population density on the rate of increase.

K-R Life Histories In K-selection, organisms live and reproduce around K, and are sensitive to population density. In r-selection, organisms exhibit high rates of reproduction and occur in variable environments in which population densities fluctuate well below K.

Human Population Predictions of the human population vary from 7.3 to 10.7 billion people by the year 2050. Will the earth be overpopulated by this time?
Ecological Footprint Six types of ecologically productive areas are distinguished in calculating the ecological footprint: Land suitable for crops. Pasture. Forest. Ocean. Built-up land. Fossil energy land.
