Q. No.The value of Z depends upon
(1) Type of taxonomic group
(2) Different Regions
(3) Area
(4) Both B and C
(1) Type of taxonomic group
(2) Different Regions
(3) Area
(4) Both B and C
Which of the following pairs will have Z value in between 0.1 to 0.2?
(1) Birds of California and frugivorous birds of tropical forests
(2) Birds of California and Molluscs in New York state
(3) Molluscs in New York state and Frugivorous birds of tropics forests
(4) Molluscs in New York state and mammals in tropical forests
If Z value is found to be 1.15, which of the following species richness was actually studied?
(1) Frugivorous birds in the tropical Forests of different continents
(2) Plants in Britain
(3) Birds in California
(4) Molluscs in New York state
If Z value is in between 0.6 to 1.2,This implies
(1) Steeper slope
(2) More towards the horizontal axis
(3) The value of species richness decreases must faster than the area explored
(4) Plants of Britain can have this value
If the area explored is entire continent, then slope of the line for species area relationship would be
(1) Much gentle
(2) Much reasonable
(3) Much steeper
(4) Both B and C
Who among the following gave tentative answers to the question that how do the attributes of stable community are related are linked to the species richness in a community?
(1) Paul Ehrlich
(2) David Tilman
(3) A V. Hamboldt
(4) Edward Wilson
Which of the following is not an attribute of stable community?
(1) Resistant to occasional disturbances
(2) Resistant to invasions by alien species
(3) Resilient to occasional disturbances
(4) High productivity with great variation year to year
Rich biodiversity is not important for
(1) Healthy ecosystem
(2) Survival of human race on this planet
(3) Alien species
(4) Both A and B
Paul Ehrlich
Which of the following is wrong about him?
(1) Stanford Ecologist
(2) Rivet Popper Hypothesis
(3) Importance of species actually affects the extent of stability of ecosystem
(4) Worked on Outdoor plots for the apology he proposed
David Tilman actually proposed that
(1) The long term ecosystem experiments using out door plots with less species showed less year to year variation in total number
(2) The long term ecosystem experiments using out door plots with more species showed less year to year variation in total biomass
(3) The long term ecosystem experiments using out door plots with more species showed more year to year variation in total number
(4) The long term ecosystem experiments using indoor plots with less species showed less year to year variation in total biomass
