Document Summary

Version q: consider a population of guppies that reproduce once a year. A reproducing one- year-old female produces on average 0. 75 female o spring that survive to reproduce. A reproducing 2-year old female produces on average 3 female o spring that survive to reproduce. 3: (1 point) write out the calculation that con rms that = 1. 92 for this population, 2 0. 6 = 1. 09: (1 point) now consider a di erent species ( species 2 ) that survives for 2 years but that has only half the fecundity per year: 1 successful female o spring per female for. 1-year-olds and 0. 3 successful female o spring per female for 2-year-olds (there is 100% survival from year 1 to year 2, and no survival after that). 1. 3: suppose the fecundity of species 2 drops by just enough to make r = 1.

You are part of a group of researchers examining the survivorship and fecundity of Bengal Tigers (Panthera tigris tigris) in the Kalakkad Mundanthurai Tiger Reserve in the South Indian state of Tamil Nadu. Parts of the reserve are well-protected from poaching, and other parts are largely unprotected. Over a period of several years, youâve gathered demographic data (summarized below) on tigers in both poached and unpoached locations; assume that mx numbers represent female offspring born per female. Note that your demographic data begins at age 1, and does not include survivorship of cubs from birth to age 1. Also, note that Sx is listed here -- this is related to, but is NOT the same as lxâ¦ To calculate r, use the formula r = ln(Ro)/T

a. Use the âunpoachedâ data to produce a life table that extends from birth (age 0) to age 8. Use this life table to estimate the probability of tiger cub survival from birth to age 1 (s1) that would be required to make the tiger population of the unpoached portion of the refuge stationary (neither growing nor shrinking). Calculate Ro, T, and r for this population.

1. Life expectancies differ across populations. Life expectancy at birth in the U.S. is currently around 78 years (76 for males; 81 for females). Consider a population in which life expectancy at birth is 50. Given what you know about life history theory, discuss how this population would differ from the U.S. across the following life history characteristics: age at first marriage, age at first reproduction, total fertility (number of children born per female), length of time spent in school, and money spent on education. Be sure to support your predictions using life history theory.

2. The following data on interbirth interval (time between births), child survivorship, and percent of children married were collected to evaluate reproductive decisions within a population. Assuming a woman of this population has a 20-year reproductive span (maximum time available from first to last birth), use these data to 1) calculate the maximum number of live births a woman could have, and 2) determine the number of births that will lead to the highest fitness (surviving children who marry) if we assume that all married children will have the same number of offspring. To receive credit, you must show your work. Lastly, what are the implications of your results?
