A particular bird species found in a certain region is subject to typical density-dependent (logistic) population growth. If the birth rate declines with increasing N according to the function birth rate b= -0.003N+3.4 and death rate increases with N according to the function d=.001N + 0.4. What is the maximum rate of growth, ‘rm’ for this population and find out the carrying capacity of this species, if the initial population size is 1800?

The rate of change of the population respect to time is gien by ) In this formula population is measured in millions of bacteria, and time.c. 0.5 in hours. Assuming that the carrying capacity of the system is 1 million bacteria, and that the initial population is million bacteria: (a) Solve this initial value problem using the separation of variables method.

a) You are studying a population of aphids with an initial
population size of 500. During a one-month period, you observe 40
births and 15 deaths in the population. Estimate the value of r for
that month, and predict the population size in three months (from
the initial population size). Remember that r is the per capita
rate of population increase. (Assume exponential population
growth).

05.02. Biologists stocked a lake with 500 fish and estimated the carrying capacity (the maximal population for the fish of that species in that lake) to be 6900. The number of fish tripled in the first year. (a) Assuming that the size of the fish population satisfies the logistic equation dP/dt=kP(1−P/K), determine the constant k, and then solve the equation to find an expression for the size of the population after t years. k=......................., P(t)=.....................
