Community Ecology-sea Otters

- Community Ecology - maritime OttersPart II Questions1 . Types of information some grampus hunt downs that scientists index need include its feed and ingest habits , food preferences , push (kcal requirement of a goliath for un concernable day , and any(prenominal) some other information cogitate to food- pull inking behavior2 . introductory prove : stick with twain macrocosms of navalic otter , one with cause of cobblers last track downs (control ) in the environ and the other with no slayer goliaths . way out the arrive of ocean otters per creation separate at the begin of the experiment , and record the crook of ocean otters at the design of the experiment per people group . Also record the births and deaths match and contrast selective informationSecond experiment : Observe a grampus whale pod in an environs with ocean otters . Record the number of ocean wolf whales (and their energy requirement [kcal] per day ) and the number of ocean otters . Calculate if the number of muddled ocean otters argon comparative to the energy requirements of the number of cause of death whales recorded3 . The presence of killer whales and declining ocean otter population in Kuluk bay tree , comp bed to the absence of killer whales and horse barn ocean otter population in Clam laguna , indicates that killer whales may real be the cause of the ocean otter population decline4 . Scientists counted all the ocean otters and did radio tracking and tagging to fill veritable that the ocean otters did non comely go anywhere (migrated ) thus decreasing the population5 . It would only get under ones skin about 8 (male ) killer whales feeding exclusively on (male ) sea otters to consume 40 ,000 of themPart III Questions6 . Killer whales ar the largest predators of warm-blooded marine mammals , the smallest of which is the sea otter . Killer whales ar cognise to feed on fishes , squids , seals , sea lions , sea turtles , otters penguins , cetaceans , among others . With these broad provender range , it is really a wonder why they are direct decimating sea otter populations .

I have thought of two reasons : one , fish populations (makes up much than 65 of their nutrition ) are now not enough to sustain them because of labored commercial fishing specially in Alaska . Thus , they are now turning to sea otters . Two , it is a cognize fact that ephemeral killer whales primarily eat marine mammals and occasionally eat fishes . I think that with global warm up and other nature disturbances , more and more killer whale pods are becoming cursory , and hence are now preferring marine mammals like sea otters as their food of prize instead of fishes7 . Hypothesis : If the sea otter populations are declining in areas where in that location 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 nab that the presence of sea otters is at one time proportional to the kelp population and inversely proportional to the population of sea urchins (sea otters food of choice . sea 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
