Considering that species diversity in estuaries is limited by constant changes in salinity, temperature, and water movement, where, vertically, in an estuary would one expect to find the greatest species diversity? The least species diversity?

What will be an ideal response?


Looking at the vertical zones of an estuary, one finds the greatest species diversity on and in the sediments of estuaries. The reason for this is that fine sediments of estuaries trap a layer of interstitial seawater that does not change its salinity and temperature as drastically as overlying water. For this reason the sediments of estuaries are more stable environments and support a greater species diversity. Below the aerobic sediments, in the anoxic zone, few species other than methanogenic bacteria are found.
