Saumon est l’une des vingt-quatre espèces de cet atlas. Ce n’est pas un catalogue : évolution, anatomie, comportement, culture, icônes, conservation et aire forment un seul système.
Les scores comparent vitesse, intelligence, aire, résilience, impact culturel et rôle écologique. Ce sont des jugements éditoriaux relatifs, pas un classement de laboratoire.
Sept chapitres creusent : origines, corps et sens, vie et comportement, culture, icônes, pression de conservation et l’aire partagée avec les gens.
Introduction profonde
Deep dive: Saumon
Saumon is not a single postcard animal. It is a set of populations, subspecies and human rules inside the fish family of this atlas.
Diversité, corps, culture et aires — plus une lentille de cette région linguistique.
Diversity inside the type
Field guides collapse many lineages into the English word Saumon. Subspecies, flyways and captive lines do not share one fate -- bald eagles and Philippine eagles, or western and mountain gorillas, are the caution.
This atlas picks a Wikipedia title as the hero image and then keeps the rest of the grade in view so a recovered stock cannot launder a CR cousin.
Life in the landscape
An adipose-finned salmonid with a kype in breeding males. Osmoregulatory gills and kidney switch twice -- downriver as smolts, upriver as adults.
Marine fat built on plankton and forage fish, then spent on the upstream fast. Semelparous Pacific bodies become the forest fertiliser.
Culture and meaning
English-language culture met the Saumon through film, law, heraldry and zoos. Those portrayals move money and sometimes take; they are not a field census.
The culture chapter dates posters and statutes so a 1975 film or a 1961 logo cannot pretend to be a 2020s Red List.
Conservation and money
Some Pacific stocks remain productive; many Atlantic and southern-US Chinook runs are endangered or extirpated behind dams.
Tourism, conflict payments, quotas and captive loans are dated economic bands in the market chapter -- not live prices and not a best-species prize.

Biology deep dive: Saumon
Saumon biology is a stack of structure, energy, sensing and hard limits. The four sections below are the same headings used across the atlas so types can be compared without a best-species frame.
Anatomie, sens, comportement et limites — plus le langage de terrain de cette région.
Structure
An adipose-finned salmonid with a kype in breeding males. Osmoregulatory gills and kidney switch twice -- downriver as smolts, upriver as adults.
Load paths and tissues (not metals) are expanded in the anatomy chapter.
Energy and foraging
Marine fat built on plankton and forage fish, then spent on the upstream fast. Semelparous Pacific bodies become the forest fertiliser.
The how-it-works diagrams reduce that budget to a six-node loop.
Senses and control
Natal-stream olfaction is the famous sense. Polarised light and magnetite help the ocean leg.
Control here means the animal steering itself -- not a vehicle ECU.
Limits
Dams, warm water, and a hatchery that smells like a factory. Climate-warmed rivers close the adult run before the gravel is reached.
Resilience scores encode those limits relative to the other 23 types.
🦅AigleBald eagles and bears are the visible customers of a Saumon pulse.
Termes clés
Anadromy
Hatch in fresh water, grow at sea, return to spawn -- the Saumon contract.
Redd
Gravel nest dug by the female; silt from logging and roads smothers it.
Semelparity
Most Pacific Saumon die after one spawning; Atlantic Saumon can repeat.
Fish ladder
Dam bypass that works for some stocks and fails for others -- Bonneville as type case.
Elwha removal
2011-14 dam teardown in Washington that became the textbook of river reset.
Hatchery mark
Clipped fins and otolith thermal marks -- the paper trail of industrial supplementation.
Habitat and movement
Where the Saumon breeds and feeds is the first constraint. Single lakes, islands and forests appear again in the history timeline.
Range scores in this atlas mark how widely that movement runs -- albatross and blue whale high, koi and panda low -- not a quality ranking.
Research and law
Named projects (Project Tiger, ACAP, ICCAT, Amboseli) are the English-language bureaucracy of the type.
Listings and downlists are dated events in the timeline, not eternal essences.
Culture and price
Film, auction and logo years are filed under culture and market so they cannot masquerade as demography.
The icons chapter keeps eight real Wikipedia titles so a later language pack can attach the same faces.
