Streams and Rivers: Habitats Partitioned at Different Spatial Scales Large-scale differences: Source to mouth. The blue line of a river on a map conveniently represents rivers as two-dimensional habitats beginning (usually) in a mountainous region, and ending in a far-off sea (or inland bas...
Here we predict that water ceases to flow for at least one day per year along 51–60 per cent of the world’s rivers by length, demonstrating that non-perennial rivers and streams are the rule rather than the exception on Earth. Leveraging global information on the hydrology, climate, ...
a paradigm shift is needed towards a new conceptual model of rivers that includes flow intermittence. By mapping the distribution of non-perennial rivers and streams, we provide a stepping-stone towards addressing this grand challenge in freshwater science. ...
Streams are of varying depths and often contain hidden rapids and whirlpools. Special attention should be paid to safety. The bottom of the water is mostly slippery pebbles, so be careful not to slip when walking in the water. Things to note in the camp area ...

a, The relative expression of microbial lifestyles (defined in theMethods) across stream-order gradient.b, One-dimensional box plots correspond to data ina, with each point (n = 53) representing a single sample and streams grouped by small (1–3), mid (4–6) and large (7–8) orde...
In the hydrologic cycle, {Blank} is greater from oceans than {Blank} over oceans, which results in greater {Blank} than {Blank} over land, which in turn accounts for why there are rivers and streams that run back to the oceans.
(b, Allakh-Yun River) and heavy (c, Selemdzha River) signs of vegetation recovery; d – completely transformed valley of the Orotukan River; e – mining sites on the small streams on the Elistratov Peninsula (Shelikhov Gulf) and f – abandoned site on the Innakh River (right ...
2). The rivers in this study are separated into five groups: 1) first- and second-order streams draining lowland (Atlantic) blanket bog lands (“Streams draining Connemara Bogs”; n = 10); 2) one monolithologic second-order stream draining limestone (the Caher River; n = 6); 3) one...
In this work, optical fiber Bragg grating sensors were used to measure water velocity and examine how it was distributed in open channels. Several types of coatings were incorporated into the design of the sensors to examine their effects on the strain that the fibers experienced as a result of...
