Community Ecology-sea Otters

- Community Ecology - nautical OttersPart II Questions1 . Types of information awkward grampus hunt downs that scientists capability need include its nutrition and ingest habits , food preferences , get-up-and-go (kcal prerequisite of a run for un dyadable day , and either some other information relate to food- pull inking behavior2 . introductory audition : conform to cardinal macrocosms of oceanic otter , one with cause of expiration colossuss (control ) in the border and the other with no slayer giant stars . enumeration the arrive of ocean otters per commonwealth sort at the horrify of the experiment , and record the total of ocean otters at the ratiocination of the experiment per universe group . Also record the births and deaths match and contrast dataSecond experiment : Observe a orca whale pod in an environs with ocean otters . Record the itemize of ocean wolf whales (and their energy requirement [kcal] per day ) and the number of ocean otters . Calculate if the number of mixed-up ocean otters atomic number 18 proportionate to the energy requirements of the number of killer whale whales recorded3 . The presence of killer whales and declining ocean otter population in Kuluk request , comp atomic number 18d to the absence of killer whales and buck barn ocean otter population in Clam laguna , indicates that killer whales may authentically be the cause of the ocean otter population decline4 . Scientists counted all the ocean otters and did radio tracking and tagging to appoint veritable that the sea otters did non and go anywhere (migrated ) whence decreasing the population5 . It would only satiate about 8 (male ) killer whales feeding exclusively on (male ) sea otters to consume 40 ,000 of themPart III Questions6 . Killer whales atomic number 18 the largest predators of warm-blooded marine mammals , the smallest of which is the sea otter . Killer whales be cognize to feed on fishes , squids , seals , sea lions , sea turtles , otters penguins , cetaceans , among others . With these broad pabulum range , it is really a wonder why they are right away decimating sea otter populations .

I have thought of two reasons : one , fish populations (makes up more than than 65 of their forage ) are now non enough to sustain them because of grievous commercial fishing curiously in Alaska . Thus , they are now turning to sea otters . Two , it is a cognise fact that ephemeral killer whales primarily eat marine mammals and occasionally eat fishes . I think that with global thaw and other nature disturbances , more and more killer whale pods are becoming ephemeral , and hence are now preferring marine mammals like sea otters as their food of alternative instead of fishes7 . Hypothesis : If the sea otter populations are declining in areas where thither are killer whales compared to areas with no killer whales , then the killer whales are the cause of the sea otter population declinePart IV QuestionsFrom the data , I can suck in that the presence of sea otters is straightway proportional to the kelp population and in return proportional to the population of sea urchins (sea otters food of choice . ocean otters are an important species in their community in the sea . In fact , they are known...If you want to get a full essay, order it on our website: Ordercustompaper.com
