Give three hypotheses for explaining why tropics show greatest levels of species richness.
What is the significance of the slope of regression in a species-area relationship?
Observe the graph and select the correct option:
Latitudinal and altitudinal gradient is shown by which of the following habitat(s)?
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 ____________.
Select the correct alternative for x and y.
Amongst the animal group given below, which one has the highest percentage of endangered species?
Which of these is true about tropical environments?
The pattern of biodiversity is affected by ______.
"Species richness increased with increased explored area but only a limit". This statement was given by.
A species-area curve is drawn by plotting the number of species against the area. How is it that when a very large area is considered the slope is steeper than that for smaller areas?
Is it true that there is more solar energy available in the tropics? Explain briefly.
Species diversity decreases as we move away from the equator towards the poles. What could be the possible reasons?
The species-area relationship is represented on a log scale as ______.
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?
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.
Choose the correct answer form the options given below:
Which of the following characteristics are seen in a stable community?
- It is strong enough to withstand environmental disturbance and recovers quickly.
- It is resistant to invasive species.
- It exhibits constant change in biomass production over a period of time.
- It has more species diversity.
