Explain, giving three reasons, why tropics show greatest levels of species diversity.
What is the significance of the slope of regression in a species-area relationship?
Observe the graph and select the correct option:
Which of the following hypothesis states: Rich species diversity leads to lesser variation in biomass production over a period of time.
Maximum species richness is observed in the ______.
In the equation: log S = log C + Z log A , S= species richness; Z = slope of line (regression coefficient); A = area; C = Y intercept. For smaller area, the value of Z ranges from ____________.
The graph of species richness and area for a number of taxa like angiospermic plants, freshwater fishes, and birds is found to be ______.
Select the correct alternative for x and y.
Which of the below mentioned regions exhibit lees seasonal variations?
Which of these is true about tropical environments?
The pattern of biodiversity is affected by ______.
Is it possible that productivity and diversity of a natural community remain constant over a time period of, say one hundred years?
Is it true that there is more solar energy available in the tropics? Explain briefly.
The relation between species richness and area for a wide variety of taxa turns out to be a rectangular hyperbola. Give a brief explanation.
Lesser variation in biomass production over a period of time is called ______.
For frugivorous (fruit-eating) birds and mammals in the tropical forests of different continents, the slope of the species-area relationship is found to be approximately ______.
The relation between species richness and area for a wide variety of taxa appears as ______.
Who observed that within a region, species richness increased with increasing explored area, to a certain limit?
When pre-reproductive and post - reproductive age group is same in structure, the population is______.
Tropical regions show greatest level of species richness because -
- Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification.
- Tropical environments are more seasonal.
- More solar energy is available in tropics.
- Constant environments promote niche specialization.
- Tropical environments are constant and predictable.
