Kin  selection  in Belding's
   ground squirrel.
<P>
   After they are weaned, females are more likely than males to live near
   close relations.
<P>
   Alarm  calls  that  warn  these relatives (kin) increase the inclusive
   fitness of the females who exhibits such altruist behavior.
<P>
   If  all of a female's close relatives are dead, she rarely gives alarm
   calls.
