Juvenile gilthead sea bream (Sparus auratus
In teleost fish, as in other vertebrates, calcium is of key importance for numerous physiological processes. The skeleton of vertebrates consists mainly of calcium phosphate and calcium carbonate. It serves an important role as it determines body shape, protective aspects (scales, bone plates) and as a buffer internal reservoir for calcium and phosphorus. In teleosts, ~99% of the whole-body cal...
متن کاملHarvest-induced disruptive selection increases variance in fitness-related traits.
The form of Darwinian selection has important ecological and management implications. Negative effects of harvesting are often ascribed to size truncation (i.e. strictly directional selection against large individuals) and resultant decrease in trait variability, which depresses capacity to buffer environmental change, hinders evolutionary rebound and ultimately impairs population recovery. How...
متن کاملHeritability estimation for growth-related traits in juvenile wild common carp (Cyprinus carpio L.) in the south of Caspian Sea
Wild common carp of the Caspian Sea is one of the important fish in the north of Iran, which has been introduced to inland aquaculture. Its genetic characteristics are investigated to set up for breeding programs that are still unknown. Using wild common carp in aquaculture is limited for uncontrolled variation in performance of fish derived from undomesticated breeders. A 7×7 factorial matin...

متن کاملStrong selection genome-wide enhances fitness trade-offs across environments and episodes of selection.
Fitness trade-offs across episodes of selection and environments influence life-history evolution and adaptive population divergence. Documenting these trade-offs remains challenging as selection can vary in magnitude and direction through time and space. Here, we evaluate fitness trade-offs at the levels of the whole organism and the quantitative trait locus (QTL) in a multiyear field study of...
