The figure above presents the results of a study of local versus regional bird species richness. and birds and butterflies in a South African forest. Examine the top panel (birds) first, where the curve appears to reach an asymptote. What does this indicate about the processes structuring the bird community It suggests that the communities are unsaturated and that the size of the regional pool determines local species richness It suggests that the communities are becoming saturated and that local processes arc likely becoming increasingly important, It does not tell us anything about the relative importance of the regional species pool and local interactions. Now examine the lower panel (butterflies), where the curve continues to rise linearly. What does this indicate about the processes structuring the butterfly community Beta diversity measures how quickly species composition changes across the landscape. There arc a variety of different ways researchers have measured beta diversity. Relatively flat. homogeneous habitats tend to have higher beta diversity. Beta diversity changes depending on the scale at which you measure it.

Solution

Q 32 indicates about Beta Diversity. According to Wittaker Beta diversity is the ratio between Regional (Gamma)and Local(Alpha) species diversity. So according to the plot Answer is \"D\"
