There was a time when hemlocks were large, pl Creeks, streams, and rivers.

NAG is excited to celebrate this 21st Anniversary party with an art showcase and silent auction. Naturally, the artists selected are all making some sort of commentary on the environment through their work. What they share is an expertise in the craft of transformation – as well as some of our fundamental values, like designing a more sustainable future for our community and reducing waste. From detritus, to cardboard, plastic bags and other found and discarded materials, we see a mess of ordinary, everyday objects reincarnated into curious, colorful statement-making pieces.. Dissolved organic matter (DOM) is an important property of lake ecosystems, resulting from the decomposition of organic matter stored in soils and of plankton in the water column. Colored dissolved organic matter (CDOM), the fraction that absorbs ultraviolet (UV) and visible light, is the controlling factor for the optical properties of many surface waters. Little is known about the mechanisms by which DOM and CDOM evolve in lakes formed during glacial retreat. As part of a larger study of the ecosystems in glacial lakes, the present project examined the quality of DOM and CDOM in lakes in SW Greenland. Nine lakes in . WHY IS PHYSICAL DIVERSITY IMPORTANT?.
