This could entail making use of character-based mostly valuation methodologies to discern biophysical values of ecological diversity, which could encompass evaluating equally instrumental and intrinsic use and non-use values and advantages of MGR. As an example, Lawrence et al. 28 spotlight that diverse subpopulations inside the exact habitat of the same species of sea cucumbers can have diverse bioactive compounds.
