– [Jim Estes] There’s
a sign when you get off the airplane there: not the end of the world but
you can see it from here. – [Tony Sinclair] They said
can a bird man study buffalo? I said of course, I ‘ll study anything! – [Jim] I knew nothing about the ocean and he said you’d be perfect for this. – [Mary E. Power] I just
had to be underwater for the rest of my life. – [Narrator] This remarkable
band of scientists went out into the world and just followed their
passion and their curiosity. – [Tony] I’ve always said that science is detective work. But at the time we started
nobody knew anything at all. – [John Terborgh] Instead of
one spider monkey in ten years I could see ten spider
monkeys in ten minutes. – [Tony] The wildebeest
in their huge numbers were determining
everything inside the park. – [John] I was stunned. I had never seen anything
like this before. (intense music) Whether it was terrestrial or aquatic, whether it was arctic or tropical, it was all working in the same way. – [Tony] We found the rules. How systems work, how the world works. – [Jim] This was a major deal. – [Robert T. Paine] The clear
message is that some animals are more important than others. – [Jim] If you lose the wrong ones, if you lose the keystones, you’re going to see very big changes. – [Sean B. Carroll] What does
this mean for you and me? It means we can use this knowledge to upgrade the places around us. – [Mary] Nature could heal itself.

  • The Serengeti Rules

    (From the book by evolutionary biologist, Sean B. Carroll)

    (Rules of regulation / How life works / to intervene in ecosystems)

    1). Keystone Species: Some animals are more equal than others. Keystone species regulate community diversity.

    2). Trophic Cascades: Some species have strong indirect effects on others through trophic cascades.

    3). Density: The regulation of some species depends upon their density (ie. numbers and distribution).

    4). Nature is resilient: Given a chance (habitat, protection, time), populations can rebound dramatically.

    In general…

    * Identify the key players (/species, factors, molecules) that regulate a process.

    * Identify the rules that govern the interactions.

    * Replace what is missing or fix broken links.

    A very informative and interesting read 🙂

  • Astonishing documentary – beautifully shot. Eye opening and informative.

  • did they just show that shot of the fish swallowing the smaller fish twice?

  • The Karen’s spaghetti’s rules.
