1) You are conducting a mark-recapture study of a population ofsnouters. During your first sampling period
you go out and catch/mark/release 141 snouters. You return to yoursnouter population 2 months later and
catch 102 snouters of which 78 are marked. Please estimate how manysnouters are in the population. Using
this type of estimation technique, what assumptions have you madeabout immigration, emigration, births,
and deaths.
2) Assume that for the snouter population rmax = 0.05, N asestimated above and K = 350.
a - For this population, calculate dN/dt based on the populationestimate you did above modeling growth
according to the exponential growth equation and what thepopulation size will be one time interval into the
future. For N use the estimate you obtained in #1 above. (Pleaserealize that dN/dt is only the rate at which
the population changes
