Coral Reefs Essay

Easter Island is an example of the tragedy of the commons in many ways. The definition of the tragedy of the commons is to overuse of natural resources, causing them to become scarce or extinct. Easter Island is an outstanding example of an environment becoming a part of the tragedy of the commons. By the diminishing natural resources, and the scarcity of the species on the island, Easter Island proves to be a part of the tragedy of the commons. Easter Island is located in the South-East Pacific

Consider the potential for complexity of salinity and circulation within an estuarine system, a partially enclosed coastal body of brackish water that has freshwater input by rivers and salt water input by marine processes. The circulation of an estuary can vary substantially across a range of time scales such as daily, seasonally, or annually. Changes in freshwater input during periods of heavy rain, fluctuations in tides, or changes in the direction that the wind is blowing can all contribute toward

The ‘shucking’ downfall of the Pacific Oyster The Pacific Oyster (Crassostrea gigas) has fallen ill to a disease named POMS (Pacific Oyster Mortality Syndrome) which is caused by the pathogen Ostreid herpesvirus-1 micro variant. (OsHV-1 micro variant). (1). This virus does not kill an infected oyster rapidly, however with the help of environmental factors, is causes death within 8 to 10 days of infection. The disease causes mass mortality in pacific oysters of all ages, spat (oyster larvae), juveniles

The mating for blue-ringed octopuses begins when a male meets a female and begins to caress her with arm. The males then climb on the females back, the female is to allow this happening while the male starts this process. The hectocotylus is inserted under the females mantle and spermatophores are let into the female's oviduct. The female then lays between 50-100 eggs and protects them by keeping them under her tentacle until they hatch about 50 days later into the planktonic paralarvae

Aurelia labiata and Aurelia aurita, or moon jellyfish, live in the waters of the Pacific Ocean ranging from San Diego, California up to the waters of Prince William, Alaska. The Aurelia labiata closely resembles the Aurelia aurita, which is a species that lives in coastal waters all around the world. This resemblance makes it difficult to establish the true range of the moon jellies. They prefer to float near the surface of warm waters near shore, particularly harbors and bays. However, they are

Marisa Trego is trying to solve a riddle. The marine biologist wants to find long-lasting ocean pollutants that no one knows about — yet. They could be toxic, causing health problems in wildlife and people. She studies dolphins to find clues about these pollutants. But when you don’t know what you’re looking for, how can you find it? Trego’s solution: Look in fat. When she did, using a new approach, she found more than 30 percent of the test samples held pollutants that no one could name. Trego

Example of an insect with incomplete metamorphosis is Dragonfly Like any insects, the dragonfly has a 3-component frame: a head, a thorax, and a protracted thin, segmented stomach. The dragonfly has 2 massive compound eyes that absorb maximum of the head. On the short thorax there are three pairs of jointed legs and pairs of long, sensitive, membranous wings. The dragonfly breathes via spiracles (tiny holes inside the abdomen). Existence cycle: A dragonfly undergoes incomplete metamorphosis. The

Tide Monster - Chase W The tide monster is the slickest one you will find. Once, there was a boy named Joe he had a lot of friends that played on the river. They used to take their boats on the river and fish. The tide monster brought the fish in and out each day.

Why is it important to check surfboard fins before selecting your surfboard? There are different parts involved in making a surfboard but the most essential of all is the surfboard fin. This is the part which controls the movement of board on the wave. This is much more like a rudder of a boat which is used to stabilize and steer the surfboard according to the wave direction. The future fins are fixed on surfboards to prevent surfers from spinning in circles while riding on the wave. This enables

Watch out before you dip those feet in the water! Next time you’re on vacation in Hawaii or Alaska, be cautious of the jellyfish that reside in these waters. The Alatina Alata and Chinorex fleckeri, most commonly known as the Hawaiian and Australian Box Jellyfish, respectively, excrete one of the most poisonous venoms when they sting. Several articles and websites post absurd remedies which claim itself as a quick fix for this problem. In fact, it’s a huge problem to be considered. Many misleading
