Question

Study the following and pick up the correct statements: \begin{itemize} \item[(I)] All the threatened species are listed in red data book \item[(II)] National parks, Sanctuaries, Biosphere Reserves etc. are some of the methods of ex-situ conservation \item[(III)] An area which is set aside, minimally disturbed for conservation of the resources of an area is called Biosphere Reserve \item[(IV)] $\beta$-diversity is measured by counting the number of taxa within a particular area \end{itemize}

• A. I, II
• B. II, III
• C. I, III
• D. II, IV

Hint:

In conservation biology, understanding different methods like ex-situ and in-situ conservation helps in evaluating species survival strategies.

Answer 1

The Correct Option is C

Step 1: The first statement about the red data book is correct because the red data book contains the list of threatened species.
Step 2: The second statement is also correct, as national parks, sanctuaries, and biosphere reserves are examples of ex-situ conservation methods.
Step 3: The third statement is correct because a biosphere reserve is a protected area for conservation that is minimally disturbed.
Step 4: The fourth statement is incorrect as $\beta$-diversity refers to the variation in species composition among ecosystems, not by counting the number of taxa within one area. Thus, the correct statements are I and III.
