Question
The purpose of this exercise is to provide you experience with calculating and interpreting data essential to the characterization of ecological populations. A review of the following terms with example calculations can be found in the Campbell text on pages 1188 (life tables) through 1198. A. Complete the following life tables (i.e., you need to finish calculating proportion alive at each age interval) and draw the two survivorship curves. Be sure and label your axes appropriately (an appropriate standard format can be found in Fig. 53.5). The data were obtained by following a cohort of individuals from two populations oflionfish from their birth till death An Indo-Pacific population of lionfish Age (years) Number alive at Proportion Lionfish on Gulf of Mexico reefs Age (years) Number alive at Proportion 0-1 1-2 2-3 Log start of year scaled to 1000 scaled to 1000 1000 start of year 9855 H 1420 3 637 2.8 244 2 2012 0-1 2655 2.831000 1-2 617 28 596 ?.? 86s 2. 809 429 2-6 655 404 2.6 6 288 2.5 439 115 2.1 16 144 941 5-6 6-7 7-8 8-9 9-10 4-5 5-6 6-7 7-8 8-9 9-10 133 a. 22 3 2 0.3 OExplanation / Answer
Identify the type of survivourship curve you obtained for each population:
The survivourship curve that have obtained for the both the population in Gulf of Mexico reefs and in the Indo-Pacifc pipulation of lionfishes is type III curve, where this type III curve represents the high mortality and low death rates.
Which of these two specis is likely to have a higher calculated r values:
The population of lionfishes at the Gulf of Mexico reefs has the highest r values, this is because this population has the highest mortality rate when compared to the population at the Indo-Pacific as well as the no of survivours at the age of 9-10 seeemly high where in Indo-Pacific population shows 0 population
