344879 Tilman found that plots with more species showed

344880 Statement A :
For many decades, ecologists believed that communities with more species, generally, tend to be less stable than those with less species.
Statement B :
A stable community should not show too much variation in productivity from year to year.

344881 Find out the correct statements w.r.t David Tilman's longterm ecosystem experiments
I. Plots with more species showed more year to year variation in total biomass
II. Increased biodiversity contribution to higher productivity
III. Plots with less species show less year to year variation in total biomass
IV. Less the species richness in a community, more is the productivity

344882 Consider the following statements w.r.t biodiversity
I. Within a region species richness increased with increasing explored area, but only upto a limit
II. Relatively more constant environment of the tropics promote niche specialization and leads to lesser species diversity
III. Keystone species drive major ecosystem functions
IV. A stable community must be resistant to invasions by alien species
