Suppose you wanted to determine whether you had adequately sampled the species richness of a given amphibian community. Which result would most likely lead to the conclusion that more sampling was needed to assess the species richness? Group of answer choices a) A high Shannon index value b) A low Shannon index value c) A linearly increasing species accumulation curve d) A species accumulation curve that reached a threshold.

A linear species accumulation curve.

Explanation:

Species accumulation curve may be defined as the curve used to determine the total number of the species present present in a particular area. Different type of species accumulation curve depending on the species richness.

The linear species accumulation curve determines that the number of species increases with the sampling. The more sampling of the amphibian community increases the number of individuals determines that it shows the linear species accumulation curve.

Thus, the correct answer is option (c).
