The hydraulic geometry relations were developed for 61 streams, 20 of them are classified as channel evolution model (CEM Types IVV and V and 41 of them are CEM streams Types II and III.
The amount of caught fish species mostly complies with the natural reference fish fauna of this stream type [27].
The low classification strengths likely resulted from the facts that: (i) most stream macroinvertebrate taxa show individualistic responses to environmental gradients; (ii) many taxa occur either across all stream types; or (iii) only sporadically in a given stream type; and (iv) only a few species show high fidelity to a given stream type.
However, it was conspicuous that the catching numbers of all caught fish species were abnormally low compared to the natural productive capacity of this stream type.
We studied the utility of tributary and stream type classifications in accounting for the variability of invertebrate biodiversity in a boreal drainage system.
Since water quality protection measures are often related to the stream type, improvement in identifying streams should improve stream protection design and help to prevent impacts on water quality and aquatic habitat.
The front-facing dual Cable Card slots (one single stream, one multi-stream) have been replaced by one slot in the rear, which we can only assume is of a multi-stream type.
Almost all typical fish species of this stream type with the exception of lake trout (Salmo trutta f. lacustris), burbot (Lota lota), and the common nase (Chondrostoma nasus) were caught at both sampling sites.
The Argen River represents a typical stream type of the Alpine foreland where brown trout (Salmo trutta f. fario), European bullhead (Cottus gobio), grayling (Thymallus thymallus), loach (Barbatula barbatula), and barbel (Barbus barbus) represent the main indigenous fish species [27].
The shortage of food sources (e.g., invertebrates) can be excluded as a possible reason for the small number of caught fish (in comparison to the natural reference fish fauna of this stream type), since the macrozoobenthos community was in a good condition.
