Explanation:

List-I	List-II
A. Robert May	III. Global species diversity at about 7 million
B. Alexander von Humboldt	I. Species-Area relationship
C. Paul Ehrlich	IV. Rivet popper hypothesis
D. David Tilman	II. Long term ecosystem experiment using outdoor plots

• Robert May made major contributions to our understanding of global species diversity, predicting that there are around 7 million species on Earth.
• Alexander von Humboldt studied the species-area relationship, which links the size of a habitat to the number of species it can support.
• The rivet popper hypothesis, suggested by Paul Ehrlich, suggests that removing specific species from an ecosystem can cause it to collapse, similar to rivets on an aeroplane.
• David Tilman used outdoor plots in long-term ecosystem experiments to explore plant community dynamics and factors affecting species diversity.
