Essay

Refer to the figure.
Figure 10
You are studying succession and colonization at two sites, site 1 and site 2. You sample the abundance of two species at the sites and determine their percent cover at each site and time period. Use the data in Figure 10 and your knowledge of the different successional paths that communities can follow to answer the following questions:
a) Are the patterns of changes in abundance of species 1 and 2 consistent across the two sites?
b) Based on the consistency of abundances of species 1 and 2 across the sites, how would you describe the successional patterns observed at sites 1 and 2? What might be driving this pattern?
