Abstract

The cosmopolitan moon jellyfish Aurelia aurita is among the most well studied Scyphozoans. Yet, jellyfish in general are highly understudied. They have a complex life cycle and can form large aggregations or blooms in some areas. They have long been perceived as a nuisance in the world’s oceans when appearing in conflict with human activities, but more recently they have also received attention as a potential resource. It is imperative to expand knowledge of jellyfish ecology and identify drivers favorable for specie occurrence and potential bloom formation. Only then can this abundant resource be utilized in a sustainable and responsible way. In this project a comprehensive A. aurita presence only dataset was compiled using citizen science data as well as more scientific based databases. A literature search was conducted to find data which complemented the dataset further. The Specie Distribution model MaxEnt was applied to identify favorable environmental variables for A. aurita occurrence and distribution and to predict suitable areas throughout the different seasons of the year.
