Dorsal hump morphology in pink salmon (Oncorhynchus gorbuscha) [PDF]

Journal of Morphology, 2013
ABSTRACTMature male Pacific salmon (Genus Oncorhynchus) develop a dorsal hump, as a secondary male sexual characteristic, during the spawning period. Previous gross anatomical studies have indicated that the dorsal humps of salmon are mainly composed of cartilaginous tissue (Davidson [1935] J Morphol 57:169–183.) However, the histological and ...

Survival of Kamchatka pink salmon as result of combined influence of density regulation and environmental factors

Известия ТИНРО, 2015
Dynamics of stock abundance and survival is similar for the pink salmon populations from East Kamchatka and West Kamchatka, obviously because of the same large-scale environmental factors influence, as the Pacific Decadal Oscillation (PDO) and the ...

Recreational anglers in Norway report widespread dislike of invasive pink salmon

People and Nature
Pink salmon have returned to Norwegian rivers at high abundance in recent odd‐numbered years (2017, 2019, 2021, 2023), presenting potential threats to native biodiversity and ecosystem services, including major sport fishing tourism for Atlantic salmon ...

Allee Effects May Slow the Spread of Parasites in a Coastal Marine Ecosystem [PDF]

, 2011
Allee effects are thought to mediate the dynamics of population colonization, particularly for invasive species. However, Allee effects acting on parasites have rarely been considered in the analogous process of infectious disease establishment and ...

De Novo Gene Transcription of Connexin Mediates Cytoplasmic Fluid Exchange and Flocking Transitions in Physiological and Cancerous Epithelial Systems

Advanced Science, EarlyView.
EGF‐induced de novo transcription of connexins Cx26 and Cx31 promotes flocking behavior that fluidizes epithelia and enables coordinated collective migration. Connexin‐driven cytoplasmic exchange mechanistically links growth‐factor signaling to invasive dynamics.

Small Nucleolar RNA Snord17 Promotes Self‐Renewal of Intestinal Stem Cells through Yy2 mRNA Export and Tead4 Activation

Advanced Science, EarlyView.
Snord17, through interaction with Thoc3, promotes nuclear export and translation of Yy2 mRNA in Snord17+/+ ISCs. The Yy2 protein subsequently binds the Tead4 promoter to promote its transcription, activating Hippo signaling, which is essential for ISC maintenance.

CHEMICAL COMPOSITION AND ENERGY CONTENT OF PACIFIC SALMONS IN THE OKHOTSK SEA

Известия ТИНРО, 2019
The main bioenergetic parameters of pacific salmons are presented on the data obtained in marine expeditions in 2003–2015. Among the examined species, the minimum energy content is registered in the muscle tissue of chum salmon and pink salmon, and the ...
