The 'rivet' in the rivet popper hypothesis is considered to represent the ______.
Extent of global diversity of invertebrates is shown in the pie diagram below. Choose the most appropriate alternative that the four portions (a-d) represent.
Which of the following hypothesis states: Rich species diversity leads to lesser variation in biomass production over a period of time.
On a log scale the relationship of species richness and area becomes linear (straight line) and is given by the equation.
With reference to graph select the correct alternative
All are true regarding graph showing species richness - area relationship, EXCEPT ______.
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 the below mentioned regions exhibit lees seasonal variations?
Which of these is true about tropical environments?
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?
There is greater biodiversity in tropical /subtropical regions than in temperate region. Explain.
Distribution of diversity on earth shows that biodiversity from higher latitudes to lower latitudes ______.
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 ______.
Which of the following hypothesis suggests that ecosystems are like aeroplanes where flight safety (ecosystem functioning) may or may not be compromised, depending upon which species are being lost?
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.
