Rivers and streams are characterized by flowing waters and are called lotic systems (as opposed to lentic systems, such as lakes). From Wordnik.com. [River] Reference
Two major categories of freshwater ecosystems can be defined as lotic (flowing water) and lentic (standing water), but large variation in size, characteristics, and location is exhibited within each. From Wordnik.com. [Freshwater ecosystems in the Arctic] Reference
In this sense the term "river" includes all kinds of watercourses, from the tiniest of brooks to the largest of rivers (the term "streams are characterized by flowing waters and are called lotic systems (as opposed to lentic systems, such as Biodiversity Institute of Ontario). From Wordnik.com. [Featured Articles - Encyclopedia of Earth] Reference
Of particular note is the wide range of lentic and lotic ecosystems. From Wordnik.com. [Tasmanian Wilderness, Australia] Reference
Changes in the importance of lotic and littoral diatoms in a high arctic lake over the last 191 years. From Wordnik.com. [Historical changes in freshwater ecosystems in the Arctic] Reference
Still smaller types of lotic systems include medium to small rivers that arise wholly within the Arctic. From Wordnik.com. [Freshwater ecosystems in the Arctic] Reference
Loss of permafrost increases the potential for many northern shallow lotic systems to dry out from a warmer temperature regime. From Wordnik.com. [Effects of climate change on general hydro-ecology in the Arctic] Reference
Changes in the timing and duration of river ice formation will also alter the dissolved oxygen (DO) regimes of arctic lotic ecosystems. From Wordnik.com. [Effects of climate change on general hydro-ecology in the Arctic] Reference
The river continuum is thus a very important concept in the overall study of lotic systems, and one that is pertinent to many of the later sections. From Wordnik.com. [River] Reference
The greatest ice-related ecological impacts of climate change on arctic lotic systems are likely to result from changes in breakup timing and intensity. From Wordnik.com. [Effects of climate change on general hydro-ecology in the Arctic] Reference
Nutrient availability often determines food availability and lotic productivity, which are believed to be major controlling factors in riverine fish production. From Wordnik.com. [Climate change effects on arctic freshwater fish populations] Reference
Sedimentary deposits in lotic systems are often poorly preserved compared to lentic systems, owing to the relatively greater reworking of most riverine deposits. From Wordnik.com. [Historical changes in freshwater ecosystems in the Arctic] Reference
The Lost Streams of Idaho constitute an unique set of isolated lotic environments that are separated from other systems by the Eastern Snake River Basalt Plains (12g). From Wordnik.com. [Ecoregions of Idaho (EPA)] Reference
The dynamics of many of the lotic (river) and lentic (lake) environments in the Arctic are related to permafrost, and freezing can reduce or even halt the flow of rivers. From Wordnik.com. [Arctic freshwater environments] Reference
For the purposes of this assessment, lotic ecosystems include rivers, streams, deltas, and estuaries, where flow regimes are a dominant hydrologic feature shaping their ecology. From Wordnik.com. [Freshwater ecosystems in the Arctic] Reference
As continuity of deposition and preservation potential are not equal in all environments, there is a systematic bias in the paleoclimatic record toward well-preserved lentic environments, and to a lesser extent wetlands, as compared to lotic systems. From Wordnik.com. [Historical changes in freshwater ecosystems in the Arctic] Reference
Dams play a major role in fragmenting and modifying aquatic habitats, transforming lotic (running water) ecosystems into lentic (standing water) and semi-lentic ecosystems, altering the flow of matter and energy, and establishing barriers to migratory species movement.
