Exam 13: Conservation Ecology

There is often a _______________ between agriculture production and biodiversity.

Which of the following are examples of a habitat that has been degraded?

Agricultural land where synthesized nitrogen fertilizer is used impacts ecosystem services because _______________.

What remains the most likely cause of biodiversity loss?

With regard to the size of a marine protected area (MPA),you would expect a MPA that is 50% of the size of an adjacent MPA to be __________ at protecting a fish population.

You want to determine how a small population of a species may survive in the future as development around their habitat increases.You have data on the survivorship and reproductive rates of this age-structured population.Ideally,you will use the results of your research to inform land managers of predicted population sizes year by year and the probability of extinction during those years.What method would you use to do this work?

It is often difficult to identify populations at risk because?

The introduction of brown tree snakes to Guam reduced the visits per tree per day of insect and bird pollinators.Which of the following choices explains what happened as a result of this reduced pollinator activity?

A(n)_________ would be a function or attribute provided in support of human interests by ecosystems.Generally,it saves a cost that would otherwise have to be paid.

A no-take zone in a marine protected area specifically:

Which of the following choices is a reason why it is important to ensure that genetic diversity is preserved in small populations?

Which of the following are accurate statements regarding taxa threatened with extinction (whether being critically endangered,endangered,or vulnerable)?

Protected areas such as _________,are large unmodified or slightly modified areas,that retain their natural character and influence without permanent or significant human habitation,that are protected and managed to preserve their natural condition,but also provide a foundation for environmentally and culturally compatible,spiritual,scientific,educational,recreational,and visitor opportunities.

Which organization established globally recognized categories of protected areas?

A strategy to preserve biodiversity with several small reserves versus one large reserve would be effective if _________

A population of frogs was reduced 60 years ago by a major outbreak of a disease.The population was reduced to a very small size (less than 300 individuals)and the frequency of mating with relatives increased.Recently,this population has been observed to have morphological defects and reduced survivorship.There has also been a reduction in fecundity.As a result the population is becoming smaller and smaller.What is happening to this population and how could it be helped?

Which of the following are explanations as to how a species may be introduced to a nonnative habitat?

Choosing between either "land sharing" or "land sparing" farming practices depends on which of the following choices?

Which of the following are classifications of risk in conservation biology?

The effectiveness of a marine protected area (MPA)may be limited by _____________.
