- Describe the three main types of dispersion patterns that can be observed in populations. Discuss at least one factor that might lead to each pattern.Contrast density-dependent versus density-independent population processes.In populations of many organisms there is an inverse relationship between the density of individuals (number per area) and the average size of the individuals. True or False?
- You are studying a density - dependent turtle population that has the following relationships for the birth rate b’ and the death rate d’ as a function of population size (N) : b’ = 0.10 + 0.03 N - 0.0005 N ^2 d’ = 0.20 + 0.01 N Plot these functions in the same graph and discuss the population dynamics of the turtle. How does this model differ from the simple logistic model with linear birth and death functions?Do density independent and/or density dependent result in carrying capacity for populations?Suppose that in maroon-fronted parrots, the number of chicks born each year in a population is compared to the number of predators in the same area. Correlation coefficient = -0.1 Number of predators From the correlation analysis, is there strong evidence that the number of predators affects the number of parrot chicks? Yes, because the number of chicks decreases as the number of predators increases. No, because the correlation coefficient is close to zero. Yes, because correlation analysis is used to determine the effect of one variable on another. No, because correlation analysis does not determine if there is a causal link between the two variables. Number of parrot chicks
- If f(A) = 0.8 and f(a) = 0.2, what is the frequency of AA if the population is at Hardy- Weinberg equilibrium? 0.2 0.16 0.32 0.64 0.8If the population has the following number of individuals: AA=3 Aa=2 aa=0 What is the frequency of each genotype? What is the frequency of each allele?In cats, the black allele (B) is dominant over white allele (b). Given a population 2000 cats, 1680 black and 320 white, determine the allele frequency, the frequency of individuals per genotype and number of individuals per genotype.
