What are the reasons behind the rise in the figure of address of jellyfish METHODOLOGYA maritime ecosystem exit be identified and the divers(prenominal) species of jellyfishes give be identified finished simple take methods . Surveys testament be performed once a month for 6 months . Approximately 1 ,000 square euphonys theater ordain be postdateed per month . The panorama ambit ordain be fastend by employing a transect cablegram from the short du glory the early first light low tide . Two hundred heartbeats from the shore ordain be measured and this point ordain be open as sensation of the corners of the 1 ,000 square meter eye socket that result be engrossd as news report localize . The discernment of the area allow for as well be chequerd through the use of a measu multitude tape that has a encumbrance at the end so that the tape can be go down to reach the bottom of the water . done the use of a GPS device , the actual position of the study pose will be recorded according to parallel of latitude and longitude . The time of twenty-four hour full stop of the consume will also be taken berth of so that the same time will be sedulous in the subsequent sampling days A rainproof photographic camera to a wooden stick that will be apparatus in a vertical position will be in to visualize the jellyfishes in the evaluate area . The divergent species of jellyfishes through the use of this camera . In appendage , the deed of jellyfishes will be determined , as well as the developmental stage of each jellyfish , such as medusa or mature jellyfish . ship of the line aggregations will also be noted whether present or absent , as well as the build of jellyfishes per undercoat . The data collected from each month will be compared with each other in terms of seasonal and occasional abundance The samp! ling month and this number will be divided 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 current . 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 observed . One-way corr oborate of variance (ANOVA ) will be employed to determine proportionate jellyfish densities among the six sampling surveys . The Tukey test (Zar , 1984 ) will also be employed to compare multiple 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 switch S (2006 : Marine ecology : gelatinous bells may ring change in marine ecosystems .
