Lotic

This particular area is subject to the transition from a more lotic environment to the lentic environment existing in the pool area.

Turning now to more lotic environments, Norelius (1967) and Bronmark and Malmqvist (1982) have studied populations of Anodonta anita and Unio pictorum inhabiting Swedish lake outlets.

2003, J. Kolding, B. Musando, N. Songore, Inshore Fishing and Fish Population Changes in Lake Kariba, Eyolf Jul-Larsen (editor), Management, co-management or no management?: major dilemmas in southern African freshwater fisheries, 2: Case studies, page 71, The rheophilic species, Chiloglanis neumanii, Opsaridium zambezense (and possibly also Leptoglanis rotundiceps) are now confined to the tributaries or the two more lotic western basins (Balon, 1974a, 1974b).

Among the main tributaries of the French Rhône River (Arve, Guiers, Ain, Saône, Isère, Eyrieux, Drôme, Ardeche, Durance, Gard), Berahou (1993) considered the lower Ain as one of the most lotic.

The stream-dwelling species are among the most lotic of anisopterous dragonflies.

Waugoshance point is an ideal consolidated substrate, wave zone habitat, and this was evidenced by the more lotic benthic fauna found there.

Very few lotic insects are strong swimmers, probably because of the energy expenditure required to swim against a current.
