An isothermal workflow for low‐cost and PCR‐free field‐based community metabarcoding
Methods in Ecology and Evolution, EarlyView.Abstract DNA metabarcoding has revolutionized our ability to monitor ecosystems. However, the method is still rarely used in developing countries where resources are limited and fieldwork is challenging. To overcome this limitation, we designed a comprehensive workflow allowing rapid community metabarcoding with minimum, self‐manufacturable equipment ...

Pratiques de repeuplements en région méditerranéenne française : cas du bassin de l'Orb (Hérault)
Knowledge and Management of Aquatic Ecosystems, 1994 Depuis la fin du siècle dernier, afin de contrôler l'abondance des populations de truites communes (Salmo trutta L.), des pratiques de repeuplements se sont mises en place de façon plus ou moins généralisée.

Egyptian Academic Journal of Biological Sciences, B. Zoology, 2013 16S rRNA gene in the salmo trutta fario and Salmo trutta caspius has been polymerized, characterized and compared with within and between of salmonids species. The full lengths of 16S rRNA gene in species of salmons were sequenced approximately 1.7 kb and deposited in GenBank. We designed one pair of primer for amplification of 16S rRNA gene in species

Biological Reviews, EarlyView.ABSTRACT The global proliferation of dams has altered flow and sediment regimes in rivers, presenting a major threat to freshwater biodiversity. Diadromous species, such as fishes, decapod crustaceans and gastropods, are particularly susceptible to fragmentation because dams obstruct their breeding migrations between coastal waters and rivers. Although

Revealing hidden sources of uncertainty in biodiversity trend assessments
Ecography, Volume 2025, Issue 5, May 2025.Idiosyncratic decisions during the biodiversity trend assessment process may limit reproducibility, whilst ‘hidden' uncertainty due to collection bias, taxonomic incompleteness, and variable taxonomic resolution may limit the reliability of reported trends.

Salmonid Biomass in Streams Around the World: A Quantitative Synthesis
Fish and Fisheries, Volume 26, Issue 3, Page 394-413, May 2025.ABSTRACT Salmonid fishes are one of the best studied fish taxa, but little is known about their biomass distribution. We created a dataset using published material for over 1000 rivers with estimated salmonid biomass, covering 27 countries, and 11 species. The distribution of salmonid biomass and production across streams was skewed to the right with a

Neurotrophin and Trk neurotrophin receptors in the inner ear of Salmo salar and Salmo trutta [PDF]
Journal of Anatomy, 2006 AbstractNeurotrophins (NTs) and their signal transducing Trk receptors play a critical role in the development and maintenance of specific neuronal populations in the nervous system of higher vertebrates. They are responsible for the innervation of the inner ear cochlear and vestibular sensory epithelia.
