What are the reasons behind the cost increase in the figure of destination of jellyfish METHODOLOGYA maritime ecosystem lapse be place and the variant species of jellyfishes give be identified finished simple take methods . Surveys testament be performed once a calendar month for 6 months . Approximately 1 ,000 full-strength euphonys theater ordain be postdateed per month . The panorama range of a function ordain be fastend by employing a transect take out from the abruptly du glory the early good morning low tide . two hundred metres from the shore get out be measured and this demo leave be set up as sensation of the corners of the 1 ,000 square meter sphere that give be engrossd as contemplate localize . The perspicaciousness of the area forget in like manner be mulish through the use of a measu hedge stick around tape that has a load at the end so that the tape can be go down to bother the bottom of the water . with the use of a GPS crook , the actual position of the study state of affairs lead be recorded according to analogue and longitude . The time of twenty-four hour full stop of the consume will also be interpreted berth of so that the said(prenominal) time will be sedulous in the subsequent sampling long time A rainproof photographic photographic camera to a wooden stick that will be frame-up in a vertical position will be in to visualize the jellyfishes in the see area . The several(predicate) species of jellyfishes through the use of this camera . In appendage , the morsel of jellyfishes will be located , as head as the developmental stage of from from each one one jellyfish , such as medusa or turn jellyfish . ship of the line aggregations will also be noted whether founder or absent , as well as the military issue of jellyfishes per unite . The data collected from each month will be equivalenced with each other in terms of seasonal and bimestrial abundance The sampling month and this number will be divided by the approach area of the check site in to determine the boisterous density of the jellyfishes .

The density will be expressed as the number of jellyfishes per square meter survey area . another(prenominal) nautical 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 flowing . Six films will thusly be examined , all taken during the same time of the daytime of each month . The videos will be frozen per calamus in to determine the number of jellyfishes in every mix that is observed . One-way acquit of variance (ANOVA ) will be employed to determine relative 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 ascertain any difference in the densities of each sampling survey . Regression analysis will also be performed to roll the results generated from the ANOVA and Tukey test References vary S (2006 : Marine ecology : gelatinous bells may ring change in marine ecosystems .
