Species Species 2 n 20 20 r 18 16 16 14 12 10 18 16 14 12 10 16 Egg 14 12 -Size 10 Size 1 23 5 6 7 89 10 11 12 13 14 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 6. How long did each individual survive? Compare the overall lifetime reproductive output of each individual. Which species has higher overall reproductive output, and how many eggs would the individual produce? 7. Based on growth patterns and the timing of reproduction, which species is closer to the K end of the r-K continuum, and which is closer to the r end of the continuum? 8. What type of reproductive strategy do these two individuals show? How did you determine this? 9. Based on the data, what appears to be the primary factor influencing when these individuals reach their highest reproductive output? Explain your reasoning. 10. Based on the body size and reproductive output of these two individuals, is there any evidence of a trade-off? Describe evidence that you think supports or does not support the hypothesis that there is a trade-offExplanation / Answer
6) species 1 survive for 15 years where as species 2 surivives for only 9 years.
Total nuber of eggs produced by species 1 in its lifetime = 1 + 2 +3 + 5 + 8 +10 + 11 + 12 + 10 + 8 + 6 = 76
Total nuber of eggs produced by species 2 in its lifetime = 5 + 10 + 18 + 18 + 18 + 18 + 18 + 18 = 123?
Therefore, speices 2 produdes more eggs.
7) Species 2 is closer to K selection strategy as the carrying capacity is constant and close to the maximum that the environment can bear.
where as species 1 is closer to r stategy where population sizes changes rapidly.
8) both species in the given example are following a iteroparous reproductive stategy.
The term iteroparity comes from the Latin itero, to repeat, and pario, to beget. An iteroparous organism is biologically capable of having offspring many times over the course of their lives.? This point is evident from the number of eggs produced over the course of the year in the given data.
9) Based on the data it appears that the reproductive output is influenced by the size of the organism. Once the species reach their maximum size, they start to attain their maximum reproductive output.
For example look at species 2, the maximum body size is 13 cm. and as soon as this is achieved, the maximum number of eggs (18) are produced. This is also observed in species 1. The maximum body size for species 1 is 18 cm. as soon as this size is obtained, the production of eggs steadyly increases before reaching a maxima.
Hence bosy size has a large influence on the production of egg
10) There apperas to be a trade off between production of eggs and body size.
If the body size is large, like in the case of species 1, the number of eggs produced is fewer (76) as compared to species 2, which produces 123 eggs with a small body size.
Also, increase in body size influence the number of eggs produced over the years. In the case of species 1, as soon as the maximum body size of 18 cm is obtained, the ggs produces increases steadly and after reaching a maxima starts to drop drastically. However this is not the case wit hteh samll bodied species 2. Here as soon as the maximum body size of 13 cm is achieved, the maximum nuber of eggs i.e.18 is produced every year.
