Technical description

Forecasted event: Probability of Occurrence of Medusae for the Freshwater Jellyfish Craspedacusta sowerbii.

Forecast region: European Continent. Grey areas are expected to be unsuitable to the establishment of the species or imply a high level of uncertainty in the predictions.

Context: The freshwater jellyfish Craspedacusta sowerbii has established in various regions worldwide, including Europe. However, the non-native distribution of the species remains poorly known, mainly due to the fact that the most visible part of its life cycle involves small medusae that only appear for a few months each year. To address this knowledge gap, our models forecast the probability of medusae occurrence for this species based on preceding environmental conditions, including temperature, precipitation, wind speed, and snow accumulation. These forecasts can guide the timing of actions aimed at identifying potential occurrence areas, even in regions or countries where the species has not yet been detected.
