Longitudinal zonation of lotic insects in the Bandama River System (Ivory Coast)
Hydrobiologia, 1985 The longitudinal zonation of three lotic insect groups, viz. Hydropsychidae (Trichoptera), Philopotamidae (Trichoptera), and the Simulium damnosum complex (Diptera) in the Bandama River System (West Africa) is anomalous when compared to the patterns known from other geographical areas: In general from the highest to the lowest riffles downstream there ...

Relationship between geological domain and physicochemical parameters in lotic system [PDF]
RBRH, 2016 In natural conditions, the characteristics of surface water and river sediments are determined by geological formation. These can be changed due to human activities and interfere with maintenance of aquatic biota.

Neotropical otter diet variation between a lentic and a lotic systems [PDF]
Therya, 2021 Neotropical otters have been scarcely studied at the northern edge of their distribution in Mexico. The species has nocturnal-twilight habits, and their principal food is fish and crustaceans. The aim of this work was to know the foraging habits of Neotropical otters ( Lontra longicaudis ) in two monitoring sites one lentic and the other one lotic ...

Morphology of lentic and lotic tadpoles from Madagascar [PDF]
, 2021 Background The morphology of anuran larvae is suggested to differ between species with tadpoles living in standing (lentic) and running (lotic) waters.

Environmental DNA, 2021 Assessments of fish communities tend to rely on capture‐based methods that, due to sampling biases, can underestimate actual species richness. Alternatively, environmental DNA (eDNA) based metabarcoding is a noncapture approach that infers species ...

Fish community shifts along a strong fluvial environmental gradient revealed by eDNA metabarcoding
Environmental DNA, 2022 Large rivers and their estuaries are structurally complex and comprise a diversity of habitats supporting a rich biodiversity. As a result, identifying and monitoring fish communities using traditional methods in such systems may often be logistically ...

Efficacy of environmental DNA to detect and quantify stream tadpoles of Odorrana splendida [PDF]
Royal Society Open Science, 2019 Environmental DNA (eDNA) can be used to detect and estimate the density of rare or secretive species, especially in aquatic systems. However, the efficacy of eDNA method has not been validated in lotic systems. We examined the efficacy of the eDNA method
