1. Calculate the densities and basal areas per hectare for each plot and group of trees and enter the results into the table below. Hint: We sampled 100 m2 plots whereas a hectare equals 10,000 m².
The relative abundance is defined as the basal area of a species relative to the total basal area of the community and is unitless. It can be calculated as follows: BA of species i Total BA The relative abundances within a plot sum to one (check your calculations this way!). Rel. Abundance of species i=- 2. Calculate the relative abundances for each plot and group of trees and enter the results into the table below. Site Plot 1 1 2 212 Relative Abundance Evergreen Deciduous
whether there is a difference in the number of evergreens vs. deciduous trees between the two sites. You may have performed a similar test in a previous course, and you definitely performed this type of test if you have completed the statistics assignment for this lab. 1. Sum the count data from your group so you have four values: . total number of evergreens in site 1, total number of deciduous trees in site 1, total number of evergreens in site 2, total number of deciduous trees in site 2. ● • • 3. Perform the correct statistical analysis to test whether there is a significant difference in the proportions of evergreen vs. deciduous trees between the sites. Include the final data that you used for your test, the name of the test, and the p-value. 4. In 2-3 sentences, interpret the p-value. If a difference was detected, describe this difference (e.g., which site had a higher proportion of evergreens or deciduous).
