From Latin lentus ("slow")


  • Many of the lentic environments are relatively shallow, and so the species within them have to be able to withstand considerable environmental variability, especially when the water bodies freeze.

    Arctic freshwater environments

  • 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.

    Arctic freshwater environments

  • As such, the Mackenzie River system offers the best example of a northern lentic system that is unlikely to be significantly affected by changes in hydrologic processes operating within the north (e.g., direct lake evaporation and precipitation) but will be dependent principally on changes in water-balance processes operating well outside the Arctic.

    Effects of climate change on general hydro-ecology in the Arctic

  • 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.

    Freshwater ecosystems in the Arctic

  • Although some wetland types may not have standing surface water at all times, they are considered lentic ecosystems for the purposes of this chapter.

    Freshwater ecosystems in the Arctic

  • Sedimentary deposits in lotic systems are often poorly preserved compared to lentic systems, owing to the relatively greater reworking of most riverine deposits.

    Historical changes in freshwater ecosystems in the Arctic

  • 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.

    Historical changes in freshwater ecosystems in the Arctic

  • Rivers and streams are characterized by flowing waters and are called lotic systems (as opposed to lentic systems, such as lakes).


  • Of particular note is the wide range of lentic and lotic ecosystems.

    Tasmanian Wilderness, Australia

  • Aquatic communities are largely lentic in nature and Mississippian-type biotic assemblages occur.
