1
Q

Coho and Chinook Salmon - Coho are more dominant salmon species, and they force the Chinook salmon out of prime water habitats into less desirable ones. Where there are no Coho, Chinook salmon take over the prime habitat.

Q

Olfactory - migrate by olfactory maps, and once they mature in the ocean , they sniff out their natal stream to breed.

A

Steelhead trout navigation capabilities

22
Q

Visual - migrate at night and use celestial sky as compass.
May learn star patterns, but have clear predisposition to learn north-south orientation. Migrate at night because winds are not as strong, and may use Big Dipper, which the lip points to the North Star.

A

Warbler navigation capabilities

23
Q

Visual - sun as compass, pigeon can adjust for its movement
Magnetic - have magnetic granules in midline of brain
Olfactory - have olfactory map, certain odors come from winds from a distinct direction

A

Pigeon navigation capabilities

24
Q

When an animal uses distinct cues to determine its position as it attempts to reach a goal

A

Navigation
