Biodiversity Patterns

Which one of the following has maximum genetic diversity in India?

1. Teak

2. Mango

3. Wheat

4. Tea

Alexander Von Humboldt described for the first time:

1. Laws of limiting factor

2. Species-Area relationships

3. Population Growth equations

4. Ecological Biodiversity

According to Alexander von Humboldt :

1.	Species richness decreases with increasing area of exploration
2.	Species richness increases with the increasing area, but only up to a limit
3.	There is no relationship between species richness and the area explored
4.	Species richness goes on increasing with increasing area of exploration

Tropical regions show greatest level of species richness because

A:	Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification.
B:	Tropical environments are more seasonal.
C:	More solar energy is available in tropics.
D:	Constant environments promote niche specialization.
E:	Tropical environments are constant and predictable.

Choose the correct answer from the options given below:

1.	A, B and E only
2.	A and B only
3.	A, B and D only
4.	A, C, D and E only

Match List-I with List-II:

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

Choose the correct answer from the options given below:

1.	A-III, B-I, C-IV, D-II	2.	A-I, B-III, C-II, D-IV
3.	A-III, B-IV, C-II, D-I	4.	A-II, B-III, C-I, D-IV
