TESTS BETWEEN TWO POPULATION LEVELS To test for differences in two population levels, using Schnabel estimates of these levels, we can again use the knowledge that x is approximately distributed as a Poisson random variable. From 1981–2001 more complex mark-release-recapture methods [16] – [18] were most commonly used, but methods were still focused on specific taxa (primarily mammals and fish).
