Large Marine Ecosystems (LMEs)—a socio-biological term—are large (≥200,000 km²) regions of the world's oceans tied to coastal areas and related to “Exclusive Economic Zones” (EEZs). LMEs include the river basins and estuaries that feed into a coastal area and extend out to the continental shelf and beyond, to the edges of deep open water. Ninety-five percent of the biomass yields from oceans are produced within or near EEZs. To keep our oceans healthy, it is important to manage and conserve these areas of our planet properly.

This book takes an illustrative scientific approach towards understanding how interwoven conditions such as hydrology, oxygen levels, and plant canopies impact the types of species that can be found in freshwater wetlands. These ‘abiotic’ factors contribute to the overall development and adaptation of microorganisms, invertebrates, vertebrates, and plants in wetlands. Even with the scientific approach, The Biology of Freshwater Wetlands is easy to read for researchers, students, and others interested in ecology.

One of the most pristine and wild areas of North America is the Canadian Northwest. It is over 400,000 square miles with less than 50,000 inhabitants, and due to its northerly location and weather, has been largely untouched by man. Author and environmentalist Sigurd F.
