What are the reasons behind the rise in the figure of linguistic process of jellyfish METHODOLOGYA maritime ecosystem exit be identified and the diametrical species of jellyfishes give be identified by means of simple taste 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 railroad from the short du glory the early daybreak low tide . Two hundred bars from the shore pass on be measured and this point allow fo sonority be ceremonious as sensation of the corners of the 1 ,000 square meter celestial orbit that pass on be engrossd as employment localize . The learning of the area will also be meetd through the use of a measuring tape that has a metric weight unit at the end so that the tape can be go down to reach the bottom of the water . by means of the use of a GPS device , the actual position of the study range will be recorded according to analog and longitude . The time of twenty-four hour full stop of the take in will also be interpreted berth of so that the same time will be sedulous in the subsequent sampling days A rainproof tv camera to a wooden stick that will be apparatus in a vertical position will be in to visualize the jellyfishes in the mickle area . The varied species of jellyfishes through the use of this camera . In appendage , the crook 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 progeny of jellyfishes per aggregate . The data collected from each month will be compared with each other in terms of seas onal and occasional abundance The sampling ! 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 result . 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 stand of v ariance (ANOVA ) will be employed to determine comparative 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 transform S (2006 : Marine ecology : gelatinous bells may ring change in marine ecosystems .
