INTRODUCTION An ecosystem is generally accepted to be an interacting system of biota and its associated physical environment. Ecologists tend to think of these systems as identifiable at many different scales with boundaries selected to highlight internal and external interactions. In this sense, an aquatic ecosystem might be identified by the dominance of water in the internal structure and functions of an area. Destinator 3 Activation Keygen For Mac Coolsand Usb Driver. here. Such systems intuitively include streams, rivers, ponds, lakes, estuaries, and oceans. Most ecologists and environmental regulators also include vegetated wetlands as members of the set of aquatic ecosystems, and many think of groundwater aquifer systems as potential members of the set.

“Aquatic and related terrestrial ecosystems” is a phrase that recognizes the impossibility of analyzing aquatic systems absent consideration of the linkages to adjacent terrestrial environments. The inclusion of “related terrestrial ecosystems” for this study is a reflection of the state of the science that recognizes the multitude of processes linking terrestrial and aquatic systems.
