Salmon make a perilous voyage upstream past hungry eagles and bears to mate in forest creeks. When the salmon die, a new journey begins – with maggots.

For salmon lovers in California, October is “the peak of the return” when hundreds of thousands of Chinook salmon leave the open ocean and swim back to their ancestral streams to spawn and die. All along the Pacific coast, starting in the early summer and stretching as late as December, salmon wait offshore for the right timing to complete their journey inland.
In Alaska, the season starts in late June, when salmon head to streams in lush coastal forests. Although this annual migration is welcomed by fishermen who catch the salmon offshore, scientists are finding a much broader and holistic function of the spawning salmon: feeding the forest.
Millions of salmon make this migratory journey -- called running -- every year, and their silvery bodies all but obscure the rivers they pass through. This throng of salmon flesh coming into Alaska’s forests is a mass movement of nutrients from the salt waters of the ocean to the forest floor. Decomposing salmon on the sides of streams not only fertilize the soil beneath them, they also provide the base of a complex food web that depends upon them.
--- Why Do Salmon Swim Upstream?
Salmon run up freshwater streams and rivers to mate. A female salmon will dig a depression in the gravel with her tails and then deposit her eggs in the hole. Male salmon swim alongside the female and release a cloud of sperm at the same. The eggs are fertilized in the running water as the female buries them under a layer of gravel.
When the eggs hatch, they spend the first part of their lives hunting and growing in their home stream before heading out to sea to spend their adulthood.
--- Why Do Salmon Die After Mating?
Salmon typically mate once and then die, though some may return to the sea and come back to mate the subsequent year. Salmon put all of their energy into mating instead of maintaining the salmon’s body for the future. This is a type of mating strategy where adults die after a single mating episode is called semelparity.

African elephants may have magnificent ears, but on the savanna, they communicate over vast distances by picking up underground signals with their sensitive, fatty feet.

Thousands of elephants roam Etosha National Park in Namibia, a nation in southwest Africa, taking turns at the park’s numerous watering holes. The elephants exchange information by emitting low-frequency sounds that travel dozens of miles under the ground on the savannah.
The sound waves come from the animals’ huge vocal chords, and distant elephants “hear” the signals with their highly sensitive feet. The sound waves spread out through the ground and air. By triangulating the two types of signals using both ears and feet, elephants can tune into the direction, distance and content of a message.
Seismic communication is the key to understanding the complex dynamics of elephant communities. There are seismic messages that are sent passively, such as when elephants eavesdrop on each others’ footsteps. More active announcements include alarm cries, mating calls and navigation instructions to the herd.
Seismic communication works with elephants because of the incredible sensitivity of their feet. Like all mammals, including humans, elephants have receptors called Pacinian corpuscles, or PCs, in their skin. PCs are hard-wired to a part of the brain where touch signals are processed, called the somatosensory cortex.
In elephants, PCs are clustered around the edge of the foot. When picking up a far-off signal, elephants sometimes press their feet into the ground, enlarging its surface by as much as 20 percent.
Strictly speaking, when elephants pick up ground vibrations in thei feet, it’s their sense of feeling, not hearing, at work. Typically hearing happens without physical contact, when airborne vibrations hit the eardrum, causing the tiny bones of the inner ear tremble and transmit a message to the brain along the auditory nerve.
But in elephants, some ground vibrations actually reach the hearing centers of the brain through a process called bone conduction.
By modeling how the elephant’s inner ear bones respond to seismic sound waves, scientists are hoping to use a bone-conduction approach develop new and better hearing aids for people. Instead of amplifying sound waves through the ear canal, these devices would transmit sound vibrations into a person’s jawbone or skull.
--- Where did you film this episode?
It was filmed in Etosha National Park in Namibia, at Menasha watering hole, which is closed to the public. We also filmed with the elephants at the Performing Animal Welfare Society (PAWS) sanctuary in San Andreas, Calif.
--- Do all elephants communicate seismically?
Both species of elephants – Asian and African – can pick up vibrations in their feet. There are some differences in anatomy between the two species, which cannot interbreed. Those include attributes related to their hearing, and probably arose as adaptations to their distinct habitats.

OWNER OF A LONELY HEART
Move yourself
You always live your life
Never thinking of the future
Prove yourself
You are the move you make
Take your chances win or loser
See yourself
You are the steps you take
You and you - and that's the only way
Shake - shake yourself
You're every move you make
So the story goes
Owner of a lonely heart
Owner of a lonely heart
Much better than - a
Owner of a broken heart
Owner of a lonely heart
tumby
Say - you don't want to chance it
You've been hurt so before
Watch it now
The eagle in the sky
How he dancin' one and only
You - lose yourself
No not for pity's sake
There's no real reason to be lonely
Be yourself
Give your free will a chance
You've got to want to succeed
tumby
Owner of a lonely heart
Owner of a lonely heart
Much better than - a
Owner of a broken heart
Owner of a lonely heart
Owner of a lonely heart
After my own decision
They confused me so
My love said never question your will at all
In the end you've got to go
Look before you leap
And don't you hesitate at all - no no
Owner of a lonely heart
tumby
Owner of a lonely heart
Owner of a lonely heart
Owner of a lonely heart
Much better than - a
Owner of a broken heart
Owner of a lonely heart
[repeat]
Owner of a lonely heart

Sooner or later each conclusion
Will decide the lonely heart
It will excite it will delight
It will give a better start
Owner of a lonely heart
tumby
Owner of a lonely heart
Don't deceive your free will at all
Don't deceive your free will at all
Don't deceive your free will at all
Just receive it
Owner of a lonely heart

90125 is the eleventh studio album from the English progressive rock band Yes, released in 1983 on Atco Records. It was the first studio album since their 1981 breakup and the first to feature Trevor Rabin, and also marked the return of vocalist Jon Anderson, who had quit the band prior to their tenth studio album of 1980. It also marked the first time in twelve years that original keyboardist Tony Kaye had appeared with the group.
The album was titled after its Atco Records catalogue number (for example, 7-90125-1 for the LP).

Dire Straits - On Every Street, On Every Street (1991)
Lyrics:
There's gotta be a record of you some place
You gotta be on somebodys books
The lowdown, a picture of your face
Your injured looks
The sacred and profane
The pleasure and the pain
Somewhere your fingerprints remain concrete
And it's your face, I'm looking for
On every street
A ladykiller, regulation tattoo
Silver spurs on his heels
Says, what can I tell you as I'm standing next to you
She threw herself under my wheels
Oh it's a dangerous road
And a hazardous load
And the fireworks over liberty explode in the heat
And it's your face I'm looking for on every street
A three-chord symphony crashes into space
The moon is hanging upside down
I don't know why it is I'm still on the case
It's a ravenous town
And you still refuse to be traced
Seems to me such a waste
And every victory has a taste that's bittersweet
And it's your face I'm looking for on every street
And it's your face I'm looking for on every street
