The data below represent a cohort of organism “X”, tracked from birth to death. Time period* Number alive at start of period Proportion surviving at start of time interval Deaths during period Rate of mortality during time period "0-1" 432 1.00 390 0.90 "1-2" 42 0.10 29 0.69 "2-3" 13 "3-4" 11 "4-5" 10 "5-6" 9 "6-7" 7 "7-8" 3 "8-9" 0 * Numbers are reported over eight equal sized time periods – these could represent days, weeks, months or years. a) Complete the table by recording survivorship (proportion alive at the start of the time period), the number of deaths and the mortality rate for each time period. For each column you need to ensure you indicate how you performed your calculation (e.g. show one example calculation or provide a formula). b) Plot a survivorship curve for species X using semi-log graph paper.

A founder population of interesting creatures is established, and the average probability of identity by descent is calculated for each subsequent generation as follows: Generation F 1 0.05 2 0.0975 3 0.142625 4 0.2283625 a) What are the effective population sizes Ne for each Generation 1 through 4, relative to Generation 0 (the founder population)? b) What is the effective population size of Generation 4 relative to Generation 3? c) Is there any evidence for changes in population size after the founder event, and if so, at which generation did the size change in the number of breeding individuals occur?

A small community that is heavily infested with mosquitoes was sprayed weekly with the insecticide DDT for several months. Daily counts providing information on mosquito population size are represented in the graph below. Provide a biological explanation for the changes in the mosquito population over time. Use the terms: insecticide resistance/resistant, natural selection, favorable trait, reproduce, mutation/sexual reproduction Use this sentence starter: At the beginning the daily mosquito count (increased/decreased) until month _, then it started to (increase/decrease).

Imagine we census a population of rabbits (assume females only) that has been occupying a barn for a few decades. On June 30, 2021, we census the population right after the reproductive season. We count 650 individuals and divide them into 4 age classes: 0-‐6 months, 6 months-‐1 year, 1 year to 1-‐and-‐a-‐half-‐years, and 1-‐ and-‐a-‐half to 2 years. 350 are in the first age class, 175 are in the second, 90 are in the third, and 35 are in the fourth. We repeat the census at six months and find that none of the newborns (0-‐6 months age class) from the first census have produced any offspring, and that 15% of them have died. We find that the 2nd age class had 75% survival and produced 500 offspring. We also find that only 10% of the 3rd age class has survived, and produced 180 offspring. All the rabbits in the 4th age died and produced zero offspring. (a) What is the life table for this population? (i.e., x, bx, sx, lx)
