Botanists surveyed the frond lengths of two species of endemic ferns, Polystichum munitum and Dryopteris expansa, growing in a humid forest reserve. Frond length is an important adaptive trait for light capture.
Some of the results from the survey are shown in the chart below.
Identify the modal frond length of Polystichum munitum.
Calculate the range of Polystichum munitum frond length as a proportion of the range of Dryopteris expansa frond length.
Give your answer to 2 significant figures.
