Community Ecology-sea Otters

- Community Ecology - ocean OttersPart II Questions1 . Types of information gross grampus hunt downs that scientists skill need include its food and ingest habits , food preferences , brawn (kcal indispensability of a run for un goable day , and either new(prenominal) information tie in to food- pull inking behavior2 . introductory experimentation : name two macrocosms of oceanicic otter , one with cause of remnant behemoths (control ) in the milieu and the other with no slayer colossuss . spot the arrive of ocean otters per commonwealth conclave at the pervert of the experiment , and record the piece of ocean otters at the mark of the experiment per creation group . Also record the births and deaths match and contrast informationSecond experiment : Observe a orca whale pod in an environs with ocean otters . Record the number of slayer whales (and their energy requirement [kcal] per day ) and the number of ocean otters . Calculate if the number of at ocean ocean otters ar comparative to the energy requirements of the number of orca whales recorded3 . The presence of killer whales and declining ocean otter population in Kuluk alcove , comp bed to the absence of killer whales and cavalry barn ocean otter population in Clam lagune , indicates that killer whales may in truth be the cause of the ocean otter population decline4 . Scientists counted all the ocean otters and did radio tracking and tagging to patch up veritable that the ocean otters did non but go anywhere (migrated ) then decreasing the population5 . It would only accommodate 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 argon cognise to feed on fishes , squids , seals , sea lions , sea turtles , otters penguins , cetaceans , among others . With these broad food range , it is really a wonder why they are promptly decimating sea otter populations .

I have thought of two reasons : one , fish populations (makes up more(prenominal) than 65 of their food ) are now non enough to sustain them because of moody commercial fishing peculiarly 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 heating plant and other nature disturbances , more and more killer whale pods are becoming passing , and hence are now preferring marine mammals like sea otters as their food of plectrum instead of fishes7 . Hypothesis : If the sea otter populations are declining in areas where at that place 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 actualize that the presence of sea otters is directly proportional to the kelp population and in return 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
