Production of Rhizostoma luteum scyphistoma, podocyst and ephyra.

, 2018
Average ratio per initial scyphistoma (n = 39) of the production of new scyphistoma, podocyst and ephyra after the scyphistomae were exposed to a drop in temperature and then a return to the regular temperature conditions (grey) and control (black ...

Global Warming and the Spread of the Introduced Jellyfish Cassiopea andromeda: Thermal Niche and Habitat Suitability in the Mediterranean Sea

Global Change Biology, Volume 31, Issue 10, October 2025.
Written Summary: Climate change is reshaping marine ecosystems, with the Mediterranean Sea among the most vulnerable due to warming and non‐native species such as the upside‐down jellyfish Cassiopea andromeda. We investigated the thermal tolerance and habitat suitability of its polyps, a key stage for reproduction and persistence.

Comparative muscle development of scyphozoan jellyfish with simple and complex life cycles [PDF]

, 2015
International audienceBackground : Simple life cycles arise from complex life cycles when one or more developmental stages are lost. This raises a fundamental question - how can an intermediate stage, such as a larva, be removed, and development still ...

Pilot‐scale evaluation of cascade anaerobic digestion of mixed municipal wastewater treatment sludges

Water Environment Research, Volume 96, Issue 7, July 2024.
This one‐year study evaluated a pilot‐scale cascade anaerobic digestion (AD) system for the treatment of mixed municipal wastewater treatment sludges in North America. The performance, stability, and digestate quality of the cascade system were analyzed and compared with those of a conventional continuous stirred tank reactor (CSTR) digester (control).

Signal‐Transduction Proteins from Caribbean Cassiopea xamachana: The Scaffolding Protein CxRACK1 Shows Conserved Molecular Signatures and Differential Expression between Larval and the Subsequent Metamorphic Stages

Aquaculture Research, Volume 2024, Issue 1, 2024.
The molecular features from the coding sequence and part of the 5′‐UTR of the scaffolding protein receptor for activated C kinase (CxRACK1) gene from the jellyfish Cassiopea xamachana were assessed by a combination of regular and inverse PCR amplifications.

Nanoplastic uptake temporarily affects the pulsing behavior in ephyrae of the moon jellyfish Aurelia sp

Ecotoxicology, 2023
The aim of this study is to investigate for the first time the uptake and ecotoxicological effects of nanoplastics (NPs) in a marine cnidarian. Ephyrae of the moon jellyfish Aurelia sp. of different ages (0 and 7 days old) were exposed to negatively charged polystyrene NPs for 24 h; then, the uptake was assessed through traditional and novel techniques,
