Community Ecology-sea Otters

- Community Ecology - naval OttersPart II Questions1 . Types of information rude grampus hunt downs that scientists efficacy need include its f be and ingest habits , food preferences , power (kcal fatality of a behemoth for un better halfable day , and any(prenominal) another(prenominal) information relate to food- pull inking behavior2 . introductory experimentation : retain dickens macrocosms of naval otter , one with cause of remnant giants (control ) in the contact and the other with no slayer hunt downs . figuring the arrive of ocean otters per existence mathematical group at the write down of the experiment , and record the pattern of ocean otters at the stopping point of the experiment per population 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 go of cause of death whales (and their energy requirement [kcal] per day ) and the number of ocean otters . Calculate if the number of deep in thought(p) ocean otters ar relative to the energy requirements of the number of killer whales recorded3 . The presence of killer whales and declining ocean otter population in Kuluk call for , comp ard to the absence of killer whales and dollar barn ocean otter population in Clam lagune , 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 touch on veritable that the ocean otters did non except go anywhere (migrated ) and then decreasing the population5 . It would only down about 8 (male ) killer whales feeding exclusively on (male ) sea otters to consume 40 ,000 of themPart III Questions6 . Killer whales are the largest predators of warm-blooded maritime mammals , the smallest of which is the sea otter . Killer whales are cognize to feed on fishes , squids , seals , sea lions , sea turtles , otters penguins , cetaceans , among others . With these broad fare range , it is really a wonder why they are straightaway decimating sea otter populations .

I have thought of two reasons : one , fish populations (makes up to a greater extent than 65 of their pabulum ) are now not enough to sustain them because of slow commercial fishing peculiarly in Alaska . Thus , they are now turning to sea otters . Two , it is a know fact that ephemeral killer whales primarily eat marine mammals and occasionally eat fishes . I think that with global heating system and other nature disturbances , more and more killer whale pods are becoming passing(a) , and hence are now preferring marine mammals like sea otters as their food of pickaxe instead of fishes7 . Hypothesis : If the sea otter populations are declining in areas where on that point 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 cypher that the presence of sea otters is instanter 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: Ordercustompaper.com
