What environmental cue primarily triggers the onset of northward migration for many baleen whales in the North Atlantic?
- A. Increase in sea surface temperature
- B. Lengthening daylight (photoperiod)
- C. Rise in krill swarm density
- D. Decrease in sea ice concentration
Which sensory mechanism is hypothesized to enable whales to detect Earth's magnetic field for long-distance navigation?
- A. Magnetoreception via cryptochromes in the retina
- B. Echolocation clicks interpreted as magnetic signatures
- C. Lateral line sensing of water currents
- D. Olfactory detection of magnetic minerals
The critically endangered vaquita exhibits which migration pattern?
- A. Seasonal migrations between the Gulf of California and the open Pacific
- B. Daily vertical migrations following prey
- C. Sedentary lifestyle with a small home range in the northern Gulf of California
- D. Transoceanic migrations to breeding grounds off Japan
Which statement best describes the migration pattern of northern elephant seals?
- A. They remain near shore year-round, foraging in kelp forests
- B. They migrate between breeding colonies on islands and feeding grounds in the open ocean, traveling thousands of kilometers
- C. They only migrate during their annual molt to warmer waters
- D. They do not migrate; individuals are resident to a single beach
How has Arctic sea‑ice loss influenced the migration behavior of narwhals?
- A. It has caused them to abandon migration and become resident
- B. It has increased their reliance on open water leads for breathing, altering dive patterns and timing
- C. It has shifted their wintering grounds further south to avoid predators
- D. It has eliminated the need for seasonal movement altogether
Which technology provides the highest‑resolution, continuous data on both location and dive depth for migrating marine mammals?
- A. Passive acoustic arrays
- B. Satellite‑linked GPS/time‑depth recorders
- C. Stable isotope analysis of baleen
- D. Photo‑identification catalogues
What physiological adaptation enables humpback whales to endure the several‑month fast during their breeding season?
- A. Ability to photosynthesize using symbiotic algae
- B. Thick blubber layer that stores energy reserves
- C. Reduced heart rate to near‑zero during dives
- D. Increased reliance on filter‑feeding while on the breeding grounds
Which description matches the migration of Southern Hemisphere humpback whales?
- A. Feed in Antarctic waters during summer, breed in tropical waters off western South America and Africa during winter
- B. Feed in the North Atlantic summer, breed in the Caribbean winter
- C. Remain in temperate coastal zones year‑round, with no long‑distance movement
- D. Undertake daily vertical migrations between surface and mesopelagic zones
What is the main obstacle to accurately modeling the migration routes of beaked whales?
- A. Their deep‑diving behavior makes satellite tag attachment and retention difficult
- B. They emit vocalizations at frequencies beyond human hearing range
- C. They exhibit highly individualized routes with little consistency
- D. Legal protections prohibit any tagging of endangered species
