Part II is devoted mainly to freshwater ecosystems, grading into the estuarine system in the last chapter. Thus, sediment organic matter (SOM) sources, and their distribution pattern, are key to understanding ecosystem material flow. We saw a small, almost inconspicuous leaf frog, even an endemic species, hiding under the leaves along the riparian zone of Balsahan River.
