7.1 Is There a Trade-Off between Current and Delayed Reproduction in the Collared Flycatcher? Suppose that you were studying a different population of collared flycatchers (Ficedula albicollis) and that you monitored the survival and reproduction of each bird throughout its entire life. Some females reproduced for the first time when they were 1 year old ("early breeders"), while others reproduced for the first time when they were 2 years old ("late breeders"). The average number of eggs laid by early breeders and late breeders of a given age are reported in the table. Average number of eggs. Age (years) Early breeders Late breeders 1 4.1 2 5.1 7.5 3 4.7 7.1 4 4.5 6.9 Question 1. Graph the average number of eggs (on the y axis) versus age (on the x axis) for both early breeders and late breeders. Please use MS Excel and copy your graph into your MS Word assignment. Question 2. Do the results suggest that it would be advantageous for birds to delay reproduction until they were 2 years old? Explain. Question 3. Do the results indicate that allocating resources to current reproduction can reduce an individual's potential for future reproduction? Explain.
