AquAdvantage salmon anadromous GM male salmon lack reproductive success and have a reduced number of surviving offspring. GM salmon's lack of fertilization success can be attributed to nest fidelity, quivering frequency, and spawn participation. Under simulated competition environments, 94% of siring occurred by wild-type salmon, while only 5.4% was attributed to GM salmon. This advantage allows more than twice as many wild-type offspring to be produced. Other characteristics that could cause wild-type males to be chosen more frequently could be the lack of growth of the kype, the hooked jaw of a male, and red coloration on anadromous males, which demonstrates sexual
The EBCC Atlas of European Breeding Birds subdivision are shown. The book concludes with sections on the Conservation Status of Europe's Birds, a list of species with threat statuses, a set of derived maps depicting overall species richness and richness of threatened species, and a 65-page references section. The book's dustjacket is illustrated by bird artist David Nurney - the front cover shows a common kingfisher (with a map of its distribution), while a European bee-eater is depicted on the spine. The European Ornithological Atlas project was initiated in 1971. Its fieldwork took the form of surveys during the breeding season, in each of the countries within
