It can also be used to demonstrate species richness and evenness. Figure 1 shows the rank- abundance curve for caddisflies (Order Trichoptera) of two aquatic habitats in northern Portugal (data from L.S.W. Tera). Pollution of streams, on the other hand, reduces the diversity of Trichoptera and several other groups of stream insects, reducing both species richness and species diversity. Interpret why those happened. These rank-abundance curves show that the mountain stream caddisfly community has higher species richness and greater species evenness. 0.1 - Mountain stream 0.01 Greater richness and species evenness 0,001 Coastal ponds 0.0001 20 40 60 80 Abundance rank Figure 1: Rank-abundance curve for caddisflies (Order Trichoptera) of two aquatic habitats in northern Portugal (data from L.S.W.

- Consider the graphic that is presented and depicts the end-point for the following scenario. At some point in the past, species A resided as a large population entirely within a rectangular geographical area. The population became divided into two isolated populations when, during a major earthquake, a mountain range arose and disrupted gene flow. Over time, the two new populations evolved independently from one another, yielding species B and C. The population comprising species C became divided into two isolated populations when another earthquake created an escarpment that disrupted gene flow. Over time, these two new populations evolved independently from one another, yielding species D and E.Imagine that you were to arrive to the region long after species D and E had evolved, completely oblivious to the scenario that is described above; survey the region for living species in this group; and conduct a cladistic analysis on those species.
