Temperature-induced sex reversal is not responsible for sex-ratio distortions in grayling Thymallus thymallus or brown trout Salmo trutta [PDF]

open access: yes, 2013
On the basis of the experiments carried out over various years, it was concluded that (1) grayling Thymallus thymallus and brown trout Salmo trutta are resistant to temperature-induced sex reversal at ecologically relevant temperatures, (2) environmental

A pyrosequencing assay for the rapid discrimination of mitochondrial lineages in the Salmo trutta species complex [PDF]

open access: yes, 2010
The European trout (Salmo trutta species complex) is genetically very diverse consisting of five distinct mitochondrial lineages that probably originated in the Pleistocene. Here, we describe a novel pyrosequencing protocol to generate two short sequence

Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

Short duration reservoir-release impacts on impounded upland rivers [PDF]

open access: yes, 2013
The increasing number and scale of river impoundments throughout the 19th and 20th centuries means that the management of these impoundments is crucial to the future of global riverine biota.
