Which of the following is true of genetic diversity and environmental disruptions

• Natural disturbances increase gen. div., human disturbances decrease it

• Genetic diversity makes ecosystems more resistant to disruptions

• Genetic diversity makes populations more resistant to env. disturbances

• Genetic diversity increases after any disturbance to an ecosystem

How does species richness relate to ecosystem resilience?

• High species richness = high resilience

• Species richness decreases as ecosystems recover from disturbances

• Low species richness = high resilience

• Species richness increases after environmental disturbances

Habitat loss impacts generalist species more than specialist species:

• True; generalist species have higher pop. sizes so they suffer more loss

• False; generalists have fewer habitat needs & are more tolerant of change

• True; generalists have more specific habitat needs and are less tolerant

• False; habitat loss impacts generalists and specialists the same

Which of the following is not a provisioning ecosystem service of trees?

• Lumber

• Oxygen

• Fruit

• Filtration of Groundwater

Which of the following is an example of an anthropogenic activity that could disrupt a supporting ecosystem service?

• Removal of native prairies that contain wildflowers to build a highway

• A fungal infection that spreads and reduces bee populations by 40%

• A forest fire that burns down a stand of trees being logged for lumber

• All are anthropogenic activities that could disrupt a supporting service

Why do islands tend to have more specialist species than generalist species?

• Generalist species aren't able to migrate to and colonize islands

• Islands have fewer available food & habitat resources than mainlands

• Generalist species have populations that are too large to live on islands

• All of the above are reasons islands have more specialists than generalists

Why do islands farther from the mainland have lower species richness than closer ones?

• Fewer species are able to migrate to farther islands

• Farther islands broke off and separated from the mainland longer ago

• Farther islands are smaller and have fewer resources than closer ones

• Fewer species can tolerate the harsh conditions on farther-away islands

Which of the following is a factor in determining the ecological tolerance of a species?

• Temperature & Precipitation

• Food resource availability

• Intraspecific competition

• Habitat availability

What happens when an environmental disturbance shifts habitat conditions outside the range of tolerance of a species?

• The species migrates to a new habitat

• The local population of that species dies out

• Genetic diversity allows the species to adapt to the new conditions

• All of the above can happen to a population after habitat disturbance
