Characterization of Marine Fauna Assemblages in the Presence of Upside-Down Jellyfish (Genus Cassiopea) at Jobos Bay National Estuarine Research Reserve (JBNERR), Puerto Rico

open access: yesDiversity
Estuaries are highly productive systems that sustain diverse assemblages of fauna. In tropical estuaries such as the Jobos Bay National Estuarine Research Reserve (JBNERR), faunal composition plays a critical role in maintaining ecosystem services ...

Host–symbiont plasticity in the upside-down jellyfish Cassiopea xamachana: strobilation across symbiont genera

open access: yesFrontiers in Ecology and Evolution
IntroductionIn the upside-down jellyfish, Cassiopea xamachana (Cnidaria: Scyphozoa), the establishment of photosymbiosis with dinoflagellates (family Symbiodiniaceae) is necessary for the sessile polyp to undergo metamorphosis (strobilation) into a free ...

Evaluating the effectiveness of drones for quantifying invasive upside-down jellyfish (Cassiopea sp.) in Lake Macquarie, Australia

open access: yesPLoS ONE, 2022
Upside-down jellyfish (Cassiopea sp.) are mostly sedentary, benthic jellyfish that have invaded estuarine ecosystems around the world. Monitoring the spread of this invasive jellyfish must contend with high spatial and temporal variability in abundance ...

Reproducible propagation technique for the symbiotic cnidarian model system Cassiopea xamachana

open access: yesBiology Open, 2022
The phylum Cnidaria is composed of corals, jellyfish, hydras, and sea anemones. Cnidarians are well-known for their regenerative capability, with many species maintaining the ability to regenerate complete structures.

The Presence of a Substrate Strengthens The Jet Generated by Upside-Down Jellyfish

open access: yesFrontiers in Marine Science, 2022
Upside-down jellyfish, Cassiopea, are prevalent in warm and shallow parts of the oceans throughout the world. They are unique among jellyfish in that they rest upside down against the substrate and extend their oral arms upwards.

Fitness of Cassiopea polyps Inoculated with Different Types of Symbionts

open access: yesIlmu Kelautan, 2022
The specificity of the relationship between cnidarian hosts and symbiotic dinoflagellates (zooxanthellae) differs among host species. Some cnidarian hosts can establish symbiotic relationship with various types of zooxanthellae, while others exhibit high

The puzzling occurrence of the upside-down jellyfish Cassiopea (Cnidaria: Scyphozoa) along the Brazilian coast: a result of several invasion events? [PDF]

open access: yesZoologia (Curitiba), 2020
The massive occurrence of jellyfish in several areas of the world is reported annually, but most of the data come from the northern hemisphere and often refer to a restricted group of species that are not in the genus Cassiopea.

High photosynthetic plasticity may reinforce invasiveness of upside-down zooxanthellate jellyfish in Mediterranean coastal waters.

open access: yesPLoS ONE, 2021
Ecological profiling of non-native species is essential to predict their dispersal and invasiveness potential across different areas of the world. Cassiopea is a monophyletic taxonomic group of scyphozoan mixotrophic jellyfish including C.

Ecology of the medusa Cassiopea xamanchana in Curaçao

open access: yes, 1971
1. Cassiopea xamachana is unable to tolerate any wave action, turbulence or currents. 2. Although the species is found only in shallow water where the light intensity is high, it could not be demonstrated that light intensity is an important factor. 3. Normal temperature fluctuations — at least in the Antilles — are of no significance as the range that

Application of environmental DNA metabarcoding and quantitative PCR to detect blooming jellyfish in a temperate bay of northern China

open access: yesEcology and Evolution, Volume 13, Issue 11, November 2023., 2023
We developed eDNA metabarcoding and quantitative PCR for the detection and assessment of jellyfish taxa in the temperate Yantai Sishili Bay (YSB) and estimated the spatial distribution of Aurelia coerulea. Our results demonstrate the potential of two eDNA techniques in jellyfish biomass investigation and jellyfish taxa detecting.
