Evolutionary BiologyFutuyma (ecology and evolution, SUNY Stony Brook) covers such subject areas as phylogeny, paleobiology, genetic mechanisms of change and speciation, character evolution, the theory of processes and macroevolution, and new molecular perspectives. Numerous line drawings, charts, diagrams, and maps are provided. Annotation copyrighted by Book News, Inc., Portland, OR |

Is biotic diversity at equilibrium , or are species still expanding their ranges from
glacial refuges , so that the current composition of communities is still affected by
history ? In some cases community composition may still be recovering from the ...

The gene frequency reaches equilibrium and is no longer changing when Aq / At
= 0. The equilibrium frequency ĝ is found by solving for q in the equation Aq / At =
( ) = u ( 1 – 9 ) – vq and is Ậ = ul ( u + v ) . Thus if u = 10-5 and v = 10- ?, the ...

A ball balanced on the tip of a pool cue is at equilibrium , but the slightest
disturbance will move it to a new position , so the cue tip is an UNSTABLE
EQUILIBRIUM point to which the ball will not return . Some genetic equilibria are
unstable .
