Two communities have the same number of species, but one is dominated by a single species while the other has more even population sizes. Which community has greater species diversity?

  1. A

    The community with one dominant species, because dominance always increases diversity

  2. B

    The community with more even population sizes, because individuals are distributed more evenly among species

  3. C

    Both communities must have equal species diversity because they have the same species richness

  4. D

    Neither community has species diversity unless every species has exactly the same population size

07

    Increasing harvest before the population declines further

  3. C

    Carefully managed seed storage to support future recovery

A conservation plan will affect local resource use. Select all planning steps that are consistent with the material.

  1. A

    Include local and Indigenous communities in decisions affecting them

  2. B

    Base decisions only on ecological evidence and ignore people's needs

  3. C

    Consider both ecological evidence and people's needs

  4. D

    Assess effects on affected people's lands, livelihoods, and resources

  5. E

    Avoid consulting communities so decisions can be made more quickly

A species is declining while the ecosystem processes it depends on are also being disrupted. Which conservation approach best reflects the scope of conservation?

  1. A

    Focus only on increasing the number of individual animals

  2. B

    Restore the affected ecosystem and maintain the processes biodiversity depends on

  3. C

    Remove all human involvement from decisions about land and water

Two communities each contain eight species. In one, a single species makes up most individuals; in the other, individuals are distributed more evenly among all eight species. Which community has greater species diversity?

  1. A

    The first community, because having one especially common species increases diversity

  2. B

    The second community, because its individuals are distributed more evenly among species

  3. C

    Neither community, because equal species richness always means equal species diversity

  4. D

    Neither community, because diversity depends only on the total number of individuals
