  2. 1 The majority of species that make up the IUCN Red List are: A mammals B aves (birds) C molluscs D amphibians

  3. 2 Which of the following international organizations is responsible for finding pragmatic solutions for the most pressing environmental challenges: A FDA B EPA C IUCN D EPBC

  4. 3 Bowhead whales were hunted almost to extinction but have started to recover after hunting was banned. If hunting were to be reinstated, the populations would rapidly decline to a severely threatened state within 5 years. This is an example of a _____________ species. A Extinct in the Wild B Conservation Dependent C Vulnerable D Endangered

  5. 4 A species that cannot be found in the wild or in captivity: A Extinct B Extinct in the Wild C Vulnerable D Conservation dependent

  6. 5 A population that has or will decrease by 90% within 10 years defines: A Extinct in the Wild B Conservation Dependent C Vulnerable D Critically Endangered

  7. 6 Population size and survival depends on all of the following EXCEPT: A The exclusion from human interactions B Rate & mortality of disease C The availability of resources D Social interactions

  8. 7 A minimum viable population (MVP) is defined as: A A minimum number of species (250 or less) that categorize a species as critically endangered B The total number of species that live within an area that is considered "highly biodiverse" C The minimum number of species required to maintain a population's adaptable level of genetic diversity D The minimum population level required to maintain reproductive rates similar to the last 5 generations of a given population

  9. 8 For a species to be considered Critically Endangered, which of the following must be true A The population of the species can be found in only one area on the planet B The population of the species totals less than 350 individuals C The population of the species totals less than 250 mature adults D The species used to be located globally, but now can only be found in one area on the globe

  10. 9 For a single population, which of the following is NOT considered a standard mechanism of extinction: A Demographic Uncertainty B Minimum Viable Uncertainty C Natural Catastrophes D Loss of genetic diversity

  11. 10 A species, such as the emperor penguin, that is not likely to decline to an endangered level, even without any regulatory protections, is categorized as: A Vulnerable B Least Concerned C Near Threatened D Conservation Dependent

  12. 11 What percent of the global population relies on fish and aquatic inverts for their main/only source of protein A 25% B 50% C 70% D 90%

  13. 12 A species that is found in large numbers in captivity, but the wild populations are declining due to habitat loss (at risk of becoming endangered) are considered: A critically endangered B near threatened C extinct in the wild D vulnerable

  14. 13 The red-tailed shark can only be found in the aquarium trade. This means that this organism is: A Extinct B Extinct in the Wild C Vulnerable D Conservation Dependent

  15. 14 Biodiveristy can be best described as A a large number of the same genetic variations B a large population within an ecosystem C a variety of species within a community D a variety of ecosystems within a population
