The per capita birth (b) and death (d) rates are measured for two populations across a range of population sizes in the attached figure. The equation for exponential growth rate is dN/dt=rN where the per capita growth rate is r=(b-d). The equation for logistic population growth rate is dN/dt=rN(1-N/K). With logistic growth, r varies as a function of the population size with density-dependent birth and/or death rates. See attached image If the death rate decreased, what would happen to the population trajectory for population A? a) increase faster b) increase slower c) decrease faster d) decrease slower
Which of the following forces can de-stabilize a population, resulting in a unstable equilibrium? a. short time lags in birth rates or death rates b. inverse density dependence c. density-dependent natality d. moderate competition e. density-dependent mortality
The per-capita birth rate of individuals in a population is 0.8, and the per-capita death rate of individuals in the same population is 0.6. Given these rates, what is happening to the size of the population? constant decreasing increasing nearing half of K random
If each adult female powerful owl produces 1 female juvenile (F) each year, the adult survival rate (Sa) is 0.8, the juvenile survival rate (Sj) is 0.4, and the population is N2022=1400 adult females and 1400 juvenile females in 2022, what will be the female population size in 2027 (N2027)? Show your calculations. (hint: use excel to set up a model and check your work)
A good number of snail population in the stagnant waters between rice paddies is growing under natural conditions with limited resources. As the snail population increases in size, how will population density affect its growth rate? a. Population density will increase and the rate of population growth will eventually slow. b. Population density will remain constant and population growth will increase. c. Population density will become unstable and population growth will stop. d. Population density will decrease and population growth will eventually increase.
Monarch butterflies are a migratory species that flies south once during the lifetime of an individual. One specific population flies to Cuba, where it encounters and shares habitat with resident monarchs that do not migrate and stay within Cuba their entire lifespan. The table shows comparisons between the two populations. What data indicate the greatest difference between the populations? A. Male to female ratioB. Difference in wing sizeC. Higher mean weightD . Average of wing angle

The chart below shows selected population data for twodifferent countries, A and B. Study the chart and answerthe questions that follow Calculate the rates of natural increase (due to birthsand deaths, not counting immigration) for the populations of country A and country B.

By now, you must have already learned a lot about POPULATION DYNAMICS. How will you know that the population size increased/decreased? What are the indicators for the increase/decrease? What factors are known to be responsible for the increase/decrease? Give as many as you can think of.
A few plant-eating salamanders manage to float on a log to a large island in the Pacific that did not have any other salamander species previously. The salamanders find the island has abundant plants for food and no predators. On average, a salamander has four offspring per year and lives for one year. Refer to the equation for the logistic growth model if you were modeling salamnder population growth with this logistic growth equation, during the first few years, a) N<K b) N=K c) N>K d) there is no relationship between N and K
The discrete logistic function (the one you can solve with your calculator) has a time lag built in = one generation. What would a greater time lag do to the outcome? increase the chances of population exceeding K decrease the chances of population exceeding K slow down population growth by decreasing r increase population growth by increasing r it would have little/no effect under all circumstances
