Consider the evolution of the population of a species of small rodents. Assume that the number of males and females are nearly equal. Due to statistical data one can assume that each female remains a juvenile for one year and then becomes an adult, and that only adults have offspring. The reproduction rate is 2. The adult surviving rate is α. The juvenile surviving rate is 2/5. Initially the population counted 100 females and 40 juveniles. What values of the adult surviving rate will ensure that the population stabilize?
The world population reached seven billion in 2011. At current growth rate, it is expected to reach eight billion by 2024 and nine billion by 2037. However, many projections predict that the world population will level off at around 9 billion individuals. Why is the world population expected to level off?
Select one:
a. The global fertility rate has been decreasing for the past 20 years and is expected to decline even further.
b. More than a third of the world population is expected to be aged 60 years or above in 2100.
c. The Earth’s carrying capacity is estimated at 9 billion individuals, when the global birth rate and death rate become equivalent.
d. Recent technological and medical advances led to increased life expectancy, allowing individuals to live longer.

- When people think about living to an age far outside of normal expectations – say to 120 or even 150 years of age – they tend to think about their own lives and what they would do with such time. Extending the human lifespan to such lengths, however, might have drastic implications for public policy and the planet as a whole. Do you think that such an increased lifespan would be good for the population? Why or why not? Be thorough in your discussion of these factors.arrow_forwardThe following equation is used to calculate the population growth rate, Ro, per generation from a life table. Iy is survival probability from birth to age x and my is fecundity at age x. Ro = Elkm Multiplying ly and my and summing it over all age categories in the life table gives the population growth rate per generation because: Calculating the reproductive output for each age class requires considering the survival probability to that age (a dead individual does not reproduce) and the fecundity at that age by multiplying them with each other. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The fecundity at each age is lower when the survival is higher because of energy constraints. Multiplying probability of survival and fecundity in each age class takes this trade-off into account. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The resulting type of growth…arrow_forwardHelp mearrow_forward
- Two stable populations employ the same fertility schedule, but different mortality schedule. In both populations, 20% of women between exact ages 45-55 bear a female child annually. No child bearing occurs outside this span. In population A, there is no mortality until age 100 where all who reached age perish. In population B, 1% of each cohort dies within each single year of age with no survivors beyond age 100. Compute GRR, GRR and r for each population. ii) Determine the birth and death rate of each. Sketch the age distribution of each.arrow_forwardDescribe the age structures in rapidly growing countries, slowly growing countries, and countries with zero population growth.arrow_forwardDescribe the three types of population pyramids and their effect on society due to their characteristics.arrow_forward
- Sea otters can eat 20%-23% of their body weight in food each day. An average sea otter weighs 23 kg (roughly 50 pounds), and there are 20-30 otters per square kilometer where they are present. An average sea urchin weighs 0.55 kg. Assuming that the otters eat only sea urchins, use these data to calculate a conservative estimate of the number of sea urchins per square kilometer that an otter population would be expected to eat each year.arrow_forwardAnswer the following questions: Why do we usually express crude birth and death rates per thousand people? Why not give the numbers per person or for the entire population. Some demographers claim that the total world population has already begun to slow, while others dispute this claim. How would you recognize a true demographic transition as opposed in mere random fluctuations in birth and death rates?arrow_forwardWhich compares to the age structure of less developed and higher developed countries, specifying the x and y axis.

- Consider the temperature effect in the sex determination of a turtle species represented in the graph below. 100 What effect would a decrease in temperature below the epivotal temperature have on sex ratios of these turtles? 50 FT MT Temperature Fewer males and females will result. None of the other answers is correct. No difference in the proportion of females to males will result as only colder temperatures will alter the sex ratio in the offspring.
