Question

California condors (Gymnogyps californianus) are listed on the IUCN Red List as being critically endangered. Since 2003, the California Condor Recovery Program has been reporting their demographic data. In 2012 they estimated the number of individuals living in the wild to be 235. If their intrinsic rate of natural increase is 0.089 ind/year, predict the size of the California condor population in 2022.

Answer 1

≈ 572

Step-by-step explanation:

Predict the size of the California condor in 2022

we can predict this value with this relation below

Nt = No*e^(rt) --- ( 1 )

where ; Nt = Future population , No = initial population, r = intrinsic rate of increase , t = time

No = 235

r = 0.089

t = 2022 - 2012 = 10

Insert values into equation 1

Nt = 235 * e^( 0.089 * 10 )

= 235 * e^0.89

≈ 572

Therefore the size of the California condor population in 2022 ≈ 572
