Summary Introduction
To write:
Calculating the Shannon Diversity Index of two forests and the highest diversity among the forests with the help of an exercise and the limitations of the Shannon Diversity Index according to the exercise
Introduction:
Shannon Diversity Index (Hs) is used to measure the species diversity of a community. It is calculated as:
Hs= -Spi lnpi
where,
Σ = summation,
pi = the proportion of the individuals belonging to a particular species in a community, and
1n = the natural logarithm.

- How can you use your data to discourage or promote logging of natural forest for human consumption?

Using the species-area relationship, you aim to estimate the number of species on a newly discovered island with an area of 220 km². Your research has established that the y-intercept of the species-area relationship (log S = log c + z log A) is 1.09 and the slope (z) is 0.38. Based on these parameters, how many species would you expect to find on this island? Group of answer choices: 34 149 82 8 92 0.65arrow_forwardIf you compare species richness and evenness along the edge versus in the center of a tree farm and then make the same comparison for a rain forest, what would you expect to find? There would probably be a greater difference in richness but less difference in evenness between the tree farm and the rain forest. There would probably be a greater difference in evenness but less difference in richness between the tree farm and the rain forest. There would probably be about the same difference between the core and the edge in the tree farm versus the rain forest. There would probably be more difference between the core and the edge in the tree farm versus the rain forest. There would probably be less difference between the core and edge in the tree farm versus the rain forest.arrow_forward
