  Does anyone of you know anything about the mesure of little carnivore
  populations with a method which involves catching one or more individuals from a
  population and injecting them with the isotope Zn-65?

  Any help will be apreciatted.

You capture and inject say 100 individuals, and let them go.  Then you come
back a month later and capture 100 individuals.  If, say, 10% of the
individuals from the second population are tagged then the total population is
100 / 10% = 1000, over the relevant area of mixing.
