61 Altruism Decrease in individual Fitness, Increase in Group

62 Inclusive Fitness

63 Hamilton’s Rule of Kin Selection: The rule is as follows: rB > C The more closely related two individuals are, the greater the value of altruism.

65 Population

69 Demography, Life Table, Cohort

70 Surviorship Curves I: Low Death Early II: Equal III. High Death Early

71 Semelparity-Big Bang Iteroparity-Constant

72 Mortality Rates-Reproduction

73 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

74 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

75 Exponential Growth

76 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.

77 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.

79 Growth Curves

80 Logistic Growth

81 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.

82 Density Dependence-Independence

83 Resource Limitations-Reproduction Rates

84 Interspecific Relationships

87 Age Structure

88 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?

89 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.
