You conduct a mark-recapture survey of eastern fence lizards (Sceloporus undulates) in a 2-hectare plot in eastern Arizona. You
Ksenya-84 [330]

Answer:

Option C

Explanation:

Given -

Total number of initially marked lizards (M) = 250

Total number of recaptured lizards (C) = 75

Total number of recaptured marked lizards (R) = 24

As we know that -

\frac{M}{N} = \frac{R}{C}

We have to find "N" . "N" is the total population size of lizards in a 2-hectare plot in eastern Arizona.

Thus, on rearranging the above equation, we get -

N = \frac{M * C}{R}

Substituting the given values in above equation, we get -

N = \frac{250 * 75}{24} \\N = 781.25\\N = 781.3

Hence, option C is correct
