Question 1) Answer yes or no to the following questions. Scenario (A) A researcher uses a model from a long term study of birth and death rates from the wild population to suggest that a population of 136 animals will go extinct within 100 years. Using 10,000 stimulations, he finds that the population went extinct in 9,547 of them. Select the true statements below. a) Is the minimum viable population size 136. b) is the model stochastic. c) Does the model include uncertainty in the population's trajectory. d) Does the population have at least a 95% chance of persisting for 100 years. e) Is it true that the only way to prevent extinction is to reduce adult mortality Scenario (B) It is argued that African giraffes should be listed under the US Endangered Species Act as they have a global population of just 70,000 individuals, and are threatened by poaching. Select the true statements below. a) Inbreeding is likely to be a serious problem for the current population of giraffes. b) Listing of giraffes under the ESA is likely to be part of a US rewilding plan. c) Allowing people to trade the right to hunt giraffes could provide a way to make hunting sustainable, and generate conservation funding. d) All trade in giraffe parts anywhere in the world would be prevented if they were listed under CITES. e) The US ESA is a suitable method for protecting giraffes because it covers all endangered species worldwide
