Jeffrey S. Levinton

Chapter 1

Charles Darwin is well known as a great marine biologist because of

• His work on coral reefs
• His classification of the barnacles
• His participation in the voyage of the H.M.S. Beagle
• All of the above

Bathybius was believed to be

• The ancestor of the bony fishes
• A slime from which life arose on the seabed
• The founder of marine biology
• A resident of hot-vent environments

Edward Forbes’s “Azoic Theory” stated that

• Life could not arise from inanimate objects
• No life can be found within the sediment
• There’s no marine life deeper than 300 fathoms
• There’s no marine life shallower than 300 fathoms

In the 19th century, Prince Albert I of Monaco was famous for

• Funding marine biology from his casino in Atlantic City
• Leading the Challenger expedition
• Outfitting oceanographic vessels and founding a lab
• All of the above

The Challenger expedition

• Circumnavigated the globe
• Helped disprove the Bathybius theory
• Produced many volumes of descriptions of marine life
• All of the above

Darwin’s theory of coral reef formation required that

• Coral reefs cease growing when sea level lowered
• Corals evolved very recently
• The rock beneath a coral reef was steadily sinking
• Volcanic islands were steadily rising under the reefs 2 / 4

The following is a scientific hypothesis:

• Blue whales cannot be seen diving, but they could dive to 1,000 m
• Mermaids will come to shore in San Francisco on May 1, 2002
• Sea otters have gills, and therefore they can dive to great depths
• None of the above

Which of the following is the best way to test a hypothesis?

• Perform an experiment that manipulates one environmental factor, holding the

others constant

• Sample the environment exhaustively, and look for close correlations among ecological

variables

• Collect a lot of information; eventually you will have enough to get the answer to your

question

• Make sure to prove the hypothesis to be true

After deciding upon a likely important effect it would be best to

• Devise a sampling scheme that measures everything in the local environment to see the

importance of the effect

• Propose a null hypothesis, which should never be rejected to prove the lack of importance

of the effect

• Propose a null hypothesis, whose rejection would prove the importance of the effect
• All of the above

Nekton

• Move only with the currents
• Include larger fish and sea mammals
• Include protistan and other very small plankton
• Are defined as swimmers who can dive very deeply

Infaunal animals are found

• Only in sea caves
• Below the tidal zone
• Within plants
• Below the sediment-water interface

Animals living in association with the sea surface are called

• Plankton
• Krypton
• Neuston 3 / 4

• Epifaunal

Pelagic habitats

• Are found in estuaries
• Are seaward of the continental shelf
• Are deep-water habitats in shelf canyons
• All of the above

Which of the following pairs are the same habitats?

• Oceanic and pelagic
• Hadal and planktonic
• Intertidal and epipelagic
• None of the above

The mesopelagic zone ranges to depths of

• 150 m
• bottom of tidal zone
• 1,000 m
• 4,000 m

Infaunal animals are usually found

• Within wood
• Buried within the sediment
• Only in the intertidal zone
• Swimming near the surface

Hadal environments are associated with

• Trenches
• The intertidal zone
• Mid-oceanic ridges
• Dinosaur habitats
