Question 31

Class and Family of Killer Whales

Answer 31

Class Mammalia Family Delphinidae

Question 32

Suborder and Family of Beluga Whales

Answer 32

Suborder Odontoceti Family Monodontidae

Question 33

Order and Family of King Penguins

Answer 33

Order Sphenisciformes Family Spheniscidae

Question 34

Contrast the benefits and limitations of using acoustic and satellite telemetry for investigating the habitat requirements and population connectivity of large marine vertebrates (cetaceans, sea turtles, sharks tunas)

Answer 34

- acoustic is best used on tunas and sharks, but would need to cover a large area with receivers, less expensive per tag - satellite is best used on air breathers like cetaceans and sea turtles who are at the surface often. Radio waves will not propagate underwater

Question 35

MPAs often increase the age/size, density, and diversity of species inside the protected area. Describe the two benefits that occur "OUTSIDE" the MPA

Answer 35

- MPA is "filled" causing the population outside the MPA to increase - Net larval export - recruitment effect - MPA area is taken over by breeding stock so baby fish move outside the MPA - Net adult export - spillover effect - adults move outside the mpa increasing other populations

Question 36

Outline the "4" steps needed to identify high priority areas for protection for sperm whales in the Gulf of Mexico. Include details on proposed methods/tools used to collect data for steps 1 and 2

Answer 36

- determine distribution patterns - estimate habitat features - Model species - Identify areas of occurrence

Question 37

What types of information (ecological) can be obtained from "multispecies" aquatic telemetry studies?

Answer 37

- prey-predator interactions - habitat partitioning - effectiveness of MPAs

Question 38

The number of banks (reefs) in the Flower Garden Banks National Marine Sanctuary

Answer 38

17
