Patterns of Biodiversity

The pattern of biodiversity is affected by ______.

What is the significance of the slope of regression in a species−area relationship?

Is it possible that productivity and diversity of a natural community remain constant over a time period of, say one hundred years?

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?

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?

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 ______.

Distribution of diversity on earth shows that biodiversity from higher latitudes to lower latitudes ______.
