Methods in Ecosystem Science edited by Oswaldo Sala, Rob Jackson, Hal Mooney, and Robert Howarth is a classic standard reference used by many (most?) ecosystem ecologists.

Is there a good field methods book that covers terrestrial ecology?
I would like to remove one of the outlets from a circuit, and run a dedicated wire to it from a separate breaker, placing it on it's own circuit.

When I disconnect the existing circuit from the receptical, that will leave pigtails for the old circuit.

What do I do with the pigtails from the old circuit that the outlet will no longer be wired to?  

-Do they need to stay in the box(which would mean they would be pigtailed in the box, but not connected to the outlet, and new wiring would also run into the box for the new circuit connected to the outlet)?

-Get pushed into the wall?

-What seems the safest thing: Remove the outlet, leave the pigtails in the box, and put a blank over it. Then cut a new hole for a new box for the receptacle and new wiring to go into.
