The California Condor (Gymnogyps californianus) is a criticallyendangered species. In 1991, 48 adults individuals were released inthe wild from the captive breeding program. In 2016, there wereapproximately 323 individuals in existence.
1.Calculate r for this time frame, assuming a continuous andconstant growth rate (2 pts).
2.What is the doubling time of this population (2 pts)?
3. 30 rabbits are introduced onto a small island at thebeginning of 2000.
4. If this population has an annual exponential growth rate(lambda) of 1.18 on the island, what was the population size at thebeginning of 2010 (2 pt)? Assume discrete growth
5. At the beginning of 2017 (2 pt)?
6. The black-footed ferret (Mustela nigripes) may be downgradedto threatened status (from endangered) once it reaches a totalpopulation size of 1300 animals in the wild. If this population hasbeen growing exponentially since 1991 at r = 0.02, calculate whenit would be downgraded to threatened status, given a population of300 animals in the wild in 2015 (2 pt). Assume continuousgrowth.
