Many of these are geographically-isolated wetlands.https://lewislab.org/wp-content/uploads/2018/03/cohenpnas_figure2_rearrange.jpgCohenPNAS_figure2_modifGeographically isolated wetlands tend to be smaller wetlands (solid black line in upper panel), and more circular. Larger wetlands tend to have irregular shapes (larger perimeter:area ratios; green dots) that deviate from circularity, which is important because many ecological functions happen on the edges of ecosystems where reactants and organisms can mix. Despite the irregular shape of large wetlands, it is small wetlands that provide most of the "edge" habitat in a landscape, as the bottom panel shows that as wetland size decline, area drops off before perimeter length does.

(Photo: K. Jimenez)https://lewislab.org/wp-content/uploads/2017/04/phosphatedesorption.jpgPhosphateDesorptionThe ability of sediment to adsorb phosphate declines sharply at the onset of saltwater intrusion, when the water mixture is less than 1% seawater. The blue and red show phosphate adsorption on two different rock types.
