Molecular characterization of aspartylglucosaminidase, a lysosomal hydrolase upregulated during strobilation in the moon jellyfish, Aurelia aurita

Bioscience, biotechnology and biochemistry, 2017
The life cycle of the moon jellyfish, Aurelia aurita, alternates between a benthic asexual polyp stage and a planktonic sexual medusa (jellyfish) stage. Transition from polyp to medusa is called strobilation.

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

Glob Chang Biol
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.

Relationship Between Asexual Reproduction of Aurelia coerulea Polyps and Jellyfish Blooms Under the Influence of Temperature Dynamics in Winter and Spring

Frontiers in Marine Science, 2022
Aurelia coerulea, a type of scyphozoan jellyfish, has massively appeared in the coastal waters of China in recent years and caused great damage, but the asexual reproduction of A. coerulea polyp predicted by local temperature could not correspond well to

Identification and Verification of the Blue Pigment in the Edible Jellyfish (Rhopilema esculentum)

Aquaculture Research, Volume 2023, Issue 1, 2023., 2023
Rhopilema esculentum is widely cultured in Chinese coastal regions and has thousand years of consumption history in China. Despite R. esculentum owns multiple colors (mainly ochre and blue) in aquaculture ponds, little is known about the pigments and color formation. This study identified and verified the blue pigment of R. esculentum.

Atlantification alters the reproduction of jellyfish Aglantha digitale in the European Arctic

Limnology and Oceanography, Volume 67, Issue 8, Page 1836-1849, August 2022., 2022
Abstract Increasing heat content, salinity, and velocity of the Atlantic water masses passing northward through the Fram Strait accelerate the transition of the European Arctic toward more Atlantic state, a process referred to as Atlantification. A pronounced environmental shift leads to a poleward expansion of boreal species ranges and alters seasonal

An environmental gradient dominates ecological and genetic differentiation of marine invertebrates between the North and Baltic Sea

Ecology and Evolution, Volume 12, Issue 5, May 2022., 2022
Environmental gradients have emerged as important barriers to structuring populations and species distributions. Using ecological and genetic data, we show that marine invertebrates exhibit significant structure across a strong salinity gradient from marine to brackish water.

Combined Effects of Temperature and Salinity on Polyps and Ephyrae of Aurelia solida (Cnidaria: Scyphozoa)

Diversity, 2021
Jellyfish outbreaks are conspicuous natural events in marine ecosystems that have a substantial impact on the structure and dynamics of marine ecosystems and different economic sectors of human activities.

The Influence of a Deep‐Water Intrusion on the Distribution of Chrysaora melanaster in the Southeastern Bering Sea

Journal of Geophysical Research: Oceans, Volume 126, Issue 6, June 2021., 2021
Abstract Scyphozoan jellyfish are conspicuous components of marine ecosystems, which during a bloom, can impact food web structure and economically important fisheries. Jellyfish biomass in the southeastern Bering Sea (SEBS) is primarily composed of Chrysaora melanaster and has varied widely over the past four decades, yet the underlying causes of ...

Transgenerational effects and temperature variation alter life history traits of the moon jellyfish

Frontiers in Marine Science, 2022
Understanding the life history strategy of organisms is key to predicting their population dynamics. The population of scyphozoan jellyfish has displayed an increasing trend in recent decades, yet its life history strategy is not fully understood.

Phylogenetic analysis of phenotypic characters of Tunicata supports basal Appendicularia and monophyletic Ascidiacea

Cladistics, Volume 36, Issue 3, Page 259-300, June 2020., 2020
Abstract With approximately 3000 marine species, Tunicata represents the most disparate subtaxon of Chordata. Molecular phylogenetic studies support Tunicata as sister taxon to Craniota, rendering it pivotal to understanding craniate evolution. Although successively more molecular data have become available to resolve internal tunicate phylogenetic ...
