Quick answers

Did wolves recover everywhere?

Global LC hides Mexican wolves, some European growing pains, and US delisting fights. Resilience here is mid-high because many Holarctic populations rebounded -- not because conflict ended.

What happened in Yellowstone in 1995?

Fourteen wolves from Canada were released (more in 1996). Elk behaviour and riparian vegetation became a long argument, not a cartoon instant forest.

Is the trophic cascade settled?

Early popular accounts over-simplified. Later work kept wolves important and added drought, human hunting, and beaver. The cascade is a research programme, not a poster.

Who was Aldo Leopold here?

A forester who had killed wolves and later wrote the mountain-as-ethics essay (1949). The US environmental canon still starts many wolf talks there.

What is Isle Royale?

A closed wolf-moose system studied since 1958. Inbreeding and later genetic rescue (2018-) made it a lab of isolation.

Are wolves more intelligent than big cats in this atlas?

Pack coordination and canine social cognition sit high. Gorillas and elephants still outrank them. Scores are relative, not IQ certificates.

IUCN: Least Concern (global)

Every gray wolf is a stack of tissues that must agree under season, prey and human pressure.

Meters below repeat the six atlas scores as gauges; they are relative marks, not laboratory certificates.

Systems

Support and integument

A long-legged canid with a sagittal crest for temporalis muscle and a dentition for both flesh and bone. Packs are families more often than Hollywood armies.

Feeding apparatus

Endurance chase and ambush on ungulates; winter moose or elk, summer more deer and beaver. Scavenge is ordinary. The feeding kit sets the ecological-role score relative to the other 23 types.

Respiration and circulation

Gas exchange and blood flow are tuned to the gray wolf energy budget -- dive, hover, sprint or bulk browse -- not to a generic vertebrate template.

Senses and neural control

Smell and a howl that spaces packs. Night hunts use hearing as much as the postcard stare.

Reproduction and ontogeny

Replacement rate is the hidden resilience number. Lead, poison, and a ballot. LC globally does not retire a rancher or a Mexican-wolf recovery plan.

Thermoregulation and salt/water

Climate and osmoregulation bound where a gray wolf can close its daily budget. Field sites in the English-speaking world still measure that envelope first.

Geographic / migratory reach
Range 75/100 -- how widely the type occupies or crosses basins.
Population security
Resilience 62/100: high means more secure (Least Concern or recovered), low means threatened. Least Concern globally after recoveries in parts of Europe and North America; Mexican and some regional wolves remain separately endangered.
Cultural charge
Cultural impact 85/100 across art, law and media -- relative, not a popularity contest.
Ecosystem leverage
Ecological role 94/100 -- engineer, keystone, pump or specialist.

Hotspots

Primary weapon or tool

The bill, teeth, trunk, pouch or talon that field guides name first -- and that trade or conflict usually targets.

Energy store

Fat, cache, crop or bamboo hours that decide whether a season closes.

Natal or breeding site

A redd, eyrie, den, anemone or ice lair -- often a single-point risk (Izumi, Natron, Gir).

Sensory organ

Smell and a howl that spaces packs. Night hunts use hearing as much as the postcard stare.

Human interface

Hunt, tourism, film or quota -- the surface where gray wolf biology meets English-language law.

Tissues & materials

Keratin and integument

Feathers, fur, baleen or skin plates -- tissues, not metals. Moult and wear are the maintenance cycle.

Bone and cartilage

Load paths for stoop, lunge, knuckle-walk or hover. Marrow and pneumatic bone differ by family.

Muscle and tendon

The expensive tissue that speed and intelligence scores only hint at.

Fat, oil and glycogen

Stores that migration, fast and lactation spend. A market for those stores (oil, ivory, fin) is a historical threat.
