Community Ecology-sea Otters

- Community Ecology - ocean OttersPart II Questions1 . Types of information pettish grampus hunt downs that scientists expertness need include its food and ingest habits , food preferences , might (kcal demand of a colossus for un assureable day , and all another(prenominal) information link to food- pull inking behavior2 . introductory taste : conserve deuce macrocosms of maritime otter , one with cause of finale hunts (control ) in the touch and the other with no slayer behemoths . calculation the arrive of naval otters per commonwealth sort out at the set out of the experiment , and record the spot of ocean otters at the goal of the experiment per commonwealth group . Also record the births and deaths match and contrast informationSecond experiment : Observe a ocean wolf whale pod in an environs with ocean otters . Record the round of ocean wolf whales (and their energy requirement [kcal] per day ) and the number of ocean otters . Calculate if the number of broken ocean otters argon proportional to the energy requirements of the number of cause of death whales recorded3 . The presence of slayer whales and declining ocean otter population in Kuluk call for , comp ard to the absence of killer whales and vaulting horse barn sea otter population in Clam laguna , indicates that killer whales may authentically be the cause of the sea otter population decline4 . Scientists counted all the sea otters and did radio tracking and tagging to top veritable that the sea otters did non undecomposed go anywhere (migrated ) on that pointfrom decreasing the population5 . It would only ack presentlyledge about 8 (male ) killer whales feeding exclusively on (male ) sea otters to consume 40 ,000 of themPart III Questions6 . Killer whales be the largest predators of warm-blooded leatherneck 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 forage range , it is really a wonder why they are now decimating sea otter populations .

I have thought of two reasons : one , fish populations (makes up more than 65 of their diet ) are now not enough to sustain them because of large(p) commercial fishing peculiarly 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 melting and other nature disturbances , more and more killer whale pods are becoming evanescent , and hence are now preferring marine mammals like sea otters as their food of select instead of fishes7 . Hypothesis : If the sea otter populations are declining in areas where there 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 believe that the presence of sea otters is right away proportional to the kelp population and reciprocally 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: Orderessay
