Lowland
The generally more turbid, warm, slow-flowing waters and fine sediment beds of lowland rivers encourage fish species with broad temperature tolerances and greater tolerances to low oxygen levels, and life history and breeding strategies adapted to these and other traits of lowland rivers. These characteristics also encourage invertebrate species with broad temperature tolerances and greater tolerances to low oxygen levels and ecologies revolving around fine sediments or alternative habitats such as submerged woody debris ("snags") or submergent macrophytes ("water weed").

Famous quotes containing the word lowland:
“The hill farmer ... always seems to make out somehow with his corn patch, his few vegetables, his rifle, and fishing rod. This self-contained economy creates in the hillman a comparative disinterest in the world’s affairs, along with a disdain of lowland ways. “I don’t go to question the good Lord in his wisdom,” runs the phrasing attributed to a typical mountaineer, “but I jest cain’t see why He put valleys in between the hills.””
—Administration in the State of Arka, U.S. public relief program (1935-1943)
“And they wrapped him up in an old cow’s hide,
And they sunk him in the Lowland sea,
And they sunk him in the Lowlands low.”
—Unknown. The Golden Vanity (l. 43–45)
“In a coign of the cliff between lowland and highland,
At the sea-down’s edge between windward and lee,
Walled round with rocks as an inland island,
The ghost of a garden fronts the sea.”
—A.C. (Algernon Charles)
