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
