5What differentiates the definitions of non-native species from invasive species?
- AImpact on native species and ecosystems
- BDistance to native range

7What is NOT a normal trait of an invasive species?
- Adoes well in disturbed habitats
- Bhuman-associated

- AHuman diseases usually originate in humans
- BMost emerging infectious diseases come from animals
- CHuman diseases usually have no link to the environment
- DMost emerging infectious diseases are vector borne diseases

rates, higher biodiversity, and intrusions into wilderness areas- AVerdadero
- BFalso
12What is NOT a potential effect of environmental change on the human disease?
- AIncreases in irrigation create habitats for disease vectors
- BMedicating livestock reduces the risks of antibiotic-resistant bacteria to humans
- CClimate change alters distributions of disease agents
- DHigher population densities increase contact rates with wildlife
13Which is not one of the Evil Quartet?
- Aintroduced predators and competitors
- Bindirect effects of predators on ecology
- Csustainable harvesting
- Dhabit loss and fragmentation
14Why might in-situ conservation be used?
- Afor species in immediate danger of going extinct without intervention

16When might ex-situ conservation be advantageous?
- Awhen species require controlled food and care to survive
- Bwhen species are very abundant in the wild
- Cwhen species cannot breed in captivity

18Sustainability, according to the Convention on Sustainable Development, is meeting the
needs of the future while compromising the needs of the present- AVerdadero
- BFalso
19The Paris Agreement was different than the Kyoto Protocol in that it
- Ais an actual treaty
- Bis based on voluntary nationally determined contributions to addressing climate change

- Densemble
22What is NOT true about scenarios
- Athere should generally just be one, best guess for a future scenario
- Bthey develop alternative sets of drivers
- Cthey are plausible, coherent, internally consistent
- Dthey often include social and economic components
23What is NOT a potential problem with scenario development?
- Apositive feedbacks that are not modeled
