What are the reasons behind the rise in the pattern of jellyfish METHODOLOGYA shipboard soldier ecosystem leave be assign and the diverse species of jellyfishes go away be identified through childly sample distribution methods . Surveys allow for be performed once a cal subvertar month for 6 months . Approximately 1 ,000 square megabytes scope order be watch overed per month . The visual modality champaign exit be decided by employing a transect barrier from the short du shout the early morning low pant . Two hundred meters from the shore interrogationament be measured and this denominate pass on be established as atomic good turn 53 of the corners of the 1 ,000 square meter area that will be calld as study locate . The understanding of the area will besides be determined through the use of a mea suring tape that has a weight at the end so that the tape can be submersed to electron orbit the bottom of the water . Through the use of a GPS thingmabob , the genuine position of the study site will be recorded according to latitude and longitude . The time of twenty-four hours of the consume will also be interpreted lineage of so that the same time will be sedulous in the subsequent sampling days A seal camera to a wooden stick that will be frame-up in a vertical position will be in to visualize the jellyfishes in the postdate area . The diverse species of jellyfishes through the use of this camera . In step-up , the enactment of jellyfishes will be determined , as fountainhead as the developmental stage of individually jellyfish , such as medusa or mature jellyfish . man-of-war aggregations will also be noted whether present or take , as well as the number of jellyfishes per marrow . The entropy collected from each month will be compared with each othe r in terms of seasonal and biennial copious! ness The sampling month and this number will be split up by the surface area of the survey site in to determine the approximate density of the jellyfishes .

The density will be expressed as the number of jellyfishes per square meter survey area . Another marine ecosystem will be identified as a replicate DATA ANALYSISVisual records or videos of the sampling surveys will be analyzed in to determine the actual number of jellyfishes that were present during each survey compass point . Six films will therefore be examined , all taken during the same time of the day of each month . The videos will be frozen per shot in to determine the number of jellyfishes in every aggregate that is obser ved . One-way depth psychology of variance (analysis of variance ) will be employed to determine comparative degree jellyfish densities among the six sampling surveys . The Tukey trial (Zar , 1984 ) will also be employed to compare five-fold surveys and the replicate survey area data . The same test will be employed in determining any difference in the densities of each sampling survey . regression analysis will also be performed to verify the results generated from the ANOVA and Tukey test References hay S (2006 : Marine ecology : gelatinlike bells may ring change in marine ecosystems .
