Question :Mutations that cause sickness and/or death after reproduction has occurred:

Question 1

options: can be passed on to future generations.

will not be passed on to future generations. are unlikely to occur.

are only passed on to future generations in species that have short life spans.

Question 2

In a population exhibiting logistic growth, what happens when the carrying capacity is exceeded?

Question 2 options:

The growth rate becomes zero until the population is back within the carrying capacity.

The growth rate becomes negative until the population is back within the carrying capacity.

The population crashes and becomes extinct.

The population's fertility drops to zero.

Question 3 How does exponential growth differ from logistic growth?

Question 3 options:

Logistic growth models take the population's age structure into account.

Long-term exponential growth is more commonly observed than long-term logistic growth in nature.

The logistic model of growth incorporates environmental limitations on population size.

Logistic growth generally comes with infinite expansion.

Question 4 Density-dependent and density-independent growth factors influence the size of a population by causing changes in the:

Question 4 options:

death rate and pattern of dispersion.

birth rate and death rate.

age structure and birth rate.

carrying capacity and age structure.

Question 5 The life history of an organism does not include the organism's

Question 5 options:

reproduction

All of these are included in an organism's life history.

death

birth

Pop 1 – Exponential Population Growth

Exercise #1 Begin with a continuously growing population of 9 individuals and an intrinsic rate of growth (r) of 0.33 per year. Project the growth of this population over the next 10 years.

Exercise #2 Decrease r from 0.33 to 0.27 and repeat exercise 1. Include a graph showing the two population trajectories.

Exercise #3 Assume that the population in exercise #1 has discrete as opposed to continuous population growth with λ = 1.40. Project the growth of this population over the next 20 years.

Exercise #4 If a continuously growing population contained 47 individuals in 2000 and 156 individuals in 2013, what is r?

Exercise #5 How many years would be required for a continuously growing population of 19 individuals with r = 0.15 to increase to a size of 500 individuals?

Exercise #6 What is the doubling time of a continuously growing population with an r = 0.007?

Exercise #7 What is the probability of extinction for a species of rare bird with an initial population size of 180, b = 1.41, d = 1.39. What if there were only 30 birds to start?

Exercise #8 Observations of an endemic salamander species in the Santa Cruz mountains have declined from 21 per transect in 1975 to 14 per transect in 2014. What is λ for this discretely growing population?

Equations

t double = ln(2)/r

P(extinction) = (d/b)^N0
