Environmental DNA Based Assessment of Fish Diversity in the Yarlung Zangbo River, Tibetan Plateau

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
The environmental DNA metabarcoding technology applied to assess fish diversity in the Yarlung Zangbo River on the Tibetan Plateau overcomes the limitations of traditional survey methods in a high elevation habitat. (1) Expanding Fish Diversity Discovery: eDNA analysis yielded the identification of 18 fish species, including 6 Tibetan endemics and the ...

Bird predation on hatchery reared Atlantic salmon smolts, Salmo salar L., released in the River Eira, Norway

open access: yesFauna Norvegica, 1987
Carlin-tagged Atlantic salmon smolts have been released in the River Eira in western Norway during the period 1961 - 1980. Just after release birds were observed as smolt predators.

Flagellins as Vaccine Adjuvants and Cancer Immunotherapy: Recent Advances and Future Prospects

open access: yesImmunology, Volume 176, Issue 3, Page 277-303, November 2025.
The figure depicts the role of flagellin in immune cells. Flagellin interacts with TLR5, resulting in the formation of homodimers and the recruitment of MyD88, which activates the IκB and MAPK signalling pathways. This results in the activation of NF‐κB and AP‐1, producing TNF‐α, IL‐6, IL‐8, and IL‐12.

Salvelinus fontinalis (Mitchill, 1814) (Salmoniformes: Salmonidae): the presence of Brook Trout in Peru [PDF]

open access: yesCheck List, 2013
Salmonidae were introduced in the Peruvian freshwaters during the first quarter of the 20th century with the Rainbow Trout, Oncorhynchus mykiss (Walbaum, 1792), and later with three more species: Salmo trutta Linnaeus, 1758, Salvelinus namaycush (Walbaum,

Patterns and Processes of Genomic Evolution Inferred From the Ten Smallest Vertebrate Genomes

open access: yesAdvanced Science, Volume 12, Issue 38, October 13, 2025.
By integrating phylogenetic relationships derived from nuclear DNA with population genetic analyses across ten pufferfish species, the genetic differentiation mechanisms underpinning the radiative speciation of the most compact vertebrate genomes has elucidated.

Extermination of Gyrodactylus salaris – infected Atlantic salmon Salmo salar by rotenone treatment in the river Vikja, Western Norway

open access: yesFauna Norvegica, 1989
Infections by Gyrodactylus salaris of Atlantic salmon in the river Vikja were discovered in 1981. To prevent further spreading of the parasite to neighbouring rivers in the Sognefiord area, the river was treated with rotenone in November 1981 and in May
