Marine fish and crustaceans abound on the coasts and in the lagoons, estuaries, and even in some upland streams.
Here is a section from his exploration of the streams and lakes of the Rhinogs, a remote mountain group in North Wales: Searching the map, I had seen some promising upland streams, a waterfall, and a tarn, so I hiked off uphill through the bracken.
Although variations in flow are evened out by Lake Constance, which is fed by upland streams as well as by the Rhine (and which also acts as a filter), they are increased again by the confluence with the Aare, which on an average carries more water than the Rhine.
The implication of these changes for monitoring eutrophication and ecological status in upland streams is discussed.
Peak flow responses in both drains and upland streams are less severe, with more rainfall being retained within the bog.
This chapter describes the principles behind the design and operation of intakes on upland streams and off rivers, canals, reservoirs, estuaries and the sea.
Characterizing flow dynamics in very small tidal creeks is complicated and not well suited to methods developed for upland streams or coastal estuaries, due to low flows, bidirectionality and shallow waters.
These findings suggest that nonpoint pollution control strategies should consider the influence of small upland streams and protection of downstream riparian zones alone is not sufficient to protect water quality.
Conversely, upland flow sources driving streamflow exert strong control on baseflow NO3-N, and in-stream attenuation through transient and permanent pathways impacts the magnitude of removal.
I found little re-colonization in assemblages of mosses and liverworts between an initial survey to a resurvey 15 years later in 0.1-ha permanent plots of upland and stream-side forest.
