I have some questions that I don't know answers

  1. True or False?:

10. In a lecture, I described the confusion over the red wolf's species identity. Which of the following concepts explains why the red wolf has been protected under the Endangered Species Act for decades (despite the uncertainty about its species status)?

Select the best answer from the options below.

Hybrid Vigor Clause

Evolutionarily Significant Unit

Biological Species Concept

Subspecies Protection Unit

15. The negative impacts of the brown-headed cowbird (a brood parasite) on songbirds have intensified due to habitat fragmentation, and this is an example of __________ ___________.

Complete the sentence with the best option from the list below.

mesoconsumer invasion

abiotic edge effects

biotic edge effects

biological invasion

18. Read the following excerpt from Leopold's A Sand County Almanac.

Based on this excerpt, what is most likely Leopold's environmental worldview (represented by the land ethic)?

"All ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts. His instincts prompt him to compete for his place in the community, but his ethics prompt him also to co-operate (perhaps in order that there may be a place to compete for). The land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land. In short, a land ethic changes the role of Homo sapiens from conqueror of the land-community to plain member and citizen of it."

--Aldo Leopold





20. In Module 5, we learned about 'ecoperception' -- specifically that the structure of our brains impacts the way we perceive risk, including environmental risk.

We learned about different 'mental shortcuts' that we use (often unknowingly) to interpret new information and gauge risk.

For example, the way information feels (the way we perceive it) is powerfully influenced by the context and meaning in which it is presented.

If I told you about a new herbal supplement that my doctor prescribed, you might be more likely to trust it (because it was recommended by a medical professional). This mental shortcut is known as _________________.


tribal cohesion

loss aversion

representative effect

21. Select any and allimpacts of roads on wildlife from the list below.

reduced gene flow

increased biological invasions

reduced wildlife-human conflicts

direct mortality of wildlife

23. Choose the best answer to fill in the blank below.

We learned about several different methods of assigning a market price to non-economic values, including _________________, which determine(s) a market price by inferring (from market transactions) how much people are willing to pay for the non-economic values.

Contingent Valuation

Replacement Costs

Hedonic Pricing


25. Evaluate the following statements describing patterns, processes, and phenomena on ISLANDS.

Select any and all TRUE statements listed below.

The extinction of endemic bird species on the island of Guam represents the devastating result of novel predation pressure from an invasive species.

Species richness on islands results from an equilibrium balance between colonization and emigration rates.

Island Biogeography Theory is useful for predicting species richness on terrestrial ‘islands’, as well as ‘true’ oceanic islands.

According to Island Biogeography Theory, we would predict that a large island that is close to the mainland would have greater species richness than a small, isolated island.

26. In the Habitat Module, you learned that habitat loss & alteration is the primary threat for many species (including songbirds & amphibians), and you also learned about a different type of tool for assessing the health of a biological community following an anthropogenic disturbance.

Bernie Krause and his colleagues monitored ___________________ to understand the impacts of logging on a forest community. Krause explained that this different kind of assessment provides a more complete sense of community health than visual cues alone.

10. Recall the case study I described in a lecture video about declining populations of Yellow Warblers in Yellowstone National Park & the Grand Tetons. I used this case study to explain source-sink dynamics, location bias of protected areas, and the importance of understanding a species' metapopulation dynamics when setting out to conserve the species. Start with definitions: What is a Sou...
