Species richness

Give the three categories, which will have the largest z value
and which will have the largest c value?

Small mammals

Nonflying insects

Birds

(please ignore the green marker)

We can represent the relationship of species richness to area with the equation: CAz n logarithmic form, A Constant Species richness Log s log c+z log A Slope Area S number of species, and c and z are both constants. High values of z indicate steeper slopes and greater increases in species number as island size increases. Habitat islands often have lower z values because they may contain more transient species that are simply passing through an area.
