Analyze your data. Theoretically each good seed could grow into a new Redbud tree. If conditions were favorable for this to occur for five years in a row and assuming that all seeds continued growing each year, what type of a population growth curve would occur?

a) logistic

b) exponential

c) Type I

d) Type III

Study the Graph above which includes data for 2 different years. Why might this data be considered more accurate than your individual data collected today?

a. Increased sample size improves the validity of the data.

b. Data taken in previous years is more accurate than the present.

c. 2017 was during a drought year so that data isn't as valid as during wet years.

Based on the data for the 2 different years, does the total infestation percentage pose a threat to reproductive potential of the Redbud tree?

a. Yes. In 2014 infestation is approximately 25% of the total good seeds produced.

b. Yes. In 2017 infestation is approximately 20% of the total good seeds produced.

c. No. Total infestations for 2014 and 2017 are only about a 1/4 of the total good seeds. There are still 75% of the seeds that are good and capable of growing.

d. No. Total infestations for 2014 and 2017 is greater than the number of good seeds, so the infestations lower the reproductive potential for the redbud.

State whether this study most likely (under-estimated or over-estimated) the reproductive potential of the Redbud tree.

a. under-estimated

b. over-estimated

1

What are possible "limiting factors" during these two years that would account for the differences in data?

a. Density dependent

b. Density independent

c. Both density dependent and independent factors
