Dynamic Model for Life History of Scyphozoa. [PDF]

PLoS ONE, 2015
A two-state life history model governed by ODEs is formulated to elucidate the population dynamics of jellyfish and to illuminate the triggering mechanism of its blooms.

Life Cycle Reversal in Aurelia sp.1 (Cnidaria, Scyphozoa).

PLoS ONE, 2015
The genus Aurelia is one of the major contributors to jellyfish blooms in coastal waters, possibly due in part to hydroclimatic and anthropogenic causes, as well as their highly adaptive reproductive traits.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti-Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa). [PDF]

Environ Toxicol
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

DNA Metabarcoding Reveals Unexpected Predator-Prey-Microbial Dynamics in the Southern Right Whale (Eubalaena australis). [PDF]

Mol Ecol
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Comparative Analysis of Convergent Jellyfish Eyes Reveals Extensive Differences in Expression of Vision-Related Genes. [PDF]

Ecol Evol
Eyes have evolved in many different lineages, including several times within jellyfish, yet the relative contributions of shared and lineage‐specific genes to convergent eyes are not known. We find that three long‐diverged species of jellyfish have mostly divergent patterns of gene expression in their eye‐bearing tissues, suggesting a major role for ...

Wind Drifting vs. Pulsating Swimming Jellyfish: Respiratory Metabolism and Composition Differences in Physalis physalis, Velella velella, Aurelia aurita, and Pelagia noctiluca

Frontiers in Marine Science, 2022
Physalia physalis and Velella velella, are among the few marine organisms that harness the wind for their locomotion, whereas other cnidarian jellyfish make use of their pulsating bell-shaped bodies to propel themselves through the seas.

Occurrence and Habitat Characteristics of Aurelia sp. Polyps in a High-Latitude Fjord

Frontiers in Marine Science, 2021
Causes and consequences of jellyfish bloom formation are subject to controversial discussions worldwide. While medusae have been studied to a broader extent, the knowledge on polyp stages of scyphozoans is limited thus hampering reliable prediction of ...

Population Structures and Levels of Connectivity for Scyphozoan and Cubozoan Jellyfish

Diversity, 2021
Understanding the hierarchy of populations from the scale of metapopulations to mesopopulations and member local populations is fundamental to understanding the population dynamics of any species.

Embryonic development of the moon jellyfish Aurelia aurita (Cnidaria, Scyphozoa): another variant on the theme of invagination [PDF]

PeerJ, 2022
Background Aurelia aurita (Scyphozoa, Cnidaria) is an emblematic species of the jellyfish. Currently, it is an emerging model of Evo-Devo for studying evolution and molecular regulation of metazoans’ complex life cycle, early development, and cell ...

On the enigma of Palaenigma wrangeli (Schmidt), a conulariid with a partly non-mineralized skeleton [PDF]

PeerJ, 2021
Palaenigma wrangeli (Schmidt) is a finger-sized fossil with a tetraradiate conical skeleton; it occurs as a rare component in fossiliferous Upper Ordovician strata of the eastern Baltic Basin and is known exclusively from north Estonia.
