Jellyfish blooms and ecological interactions [PDF]

open access: yesMarine Ecology Progress Series, 2014
Scientific and public interest in the biology and ecology of gelatinous zooplankton (jellyfish) has increased significantly over the past two decades. This Theme Section represents the proceedings of the 4th International Jellyfish Blooms Symposium held in Hiroshima, Japan, in June 2013; to date, this was the largest meeting ever of the international ...

The effects of decomposing invasive jellyfish on biogeochemical fluxes and microbial dynamics in an ultra-oligotrophic sea [PDF]

open access: yesBiogeosciences, 2020
Over the past several decades, jellyfish blooms have intensified spatially and temporally, affecting functions and services of ecosystems worldwide. At the demise of a bloom, an enormous amount of jellyfish biomass sinks to the seabed and decomposes ...

Recurrent jellyfish blooms are a consequence of global oscillations [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
A perceived recent increase in global jellyfish abundance has been portrayed as a symptom of degraded oceans. This perception is based primarily on a few case studies and anecdotal evidence, but a formal analysis of global temporal trends in jellyfish populations has been missing.

Is the Presence of Jellyfish Problematic or Beneficial?

open access: yesWalailak Journal of Science and Technology, 2013
Jellyfish are a diverse group of animals. The group consists of Chordata, Ctenophora and, mainly, Cnidaria. Jellyfish are often thought to be harmful, but few can cause fatality in humans.

Identification of genetically and oceanographically distinct blooms of jellyfish [PDF]

open access: yesJournal of The Royal Society Interface, 2013
Reports of nuisance jellyfish blooms have increased worldwide during the last half-century, but the possible causes remain unclear. A persistent difficulty lies in identifying whether blooms occur owing to local or regional processes.

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

open access: yesFrontiers 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 ...

Tracking Jellyfish Swarm Origins Using a Combined Oceanographic-Genetic-Citizen Science Approach

open access: yesFrontiers in Marine Science, 2022
Biological invasions of jellyfish may critically affect ecosystems and ecosystem services, yet their complex life cycle makes tracking their origins and dispersal vectors a challenging task.

Fluctuation and diversity of Hydromedusae (Hydrozoa, Cnidaria) in a highly productive region of the Gulf of Mexico inferred from high frequency plankton sampling [PDF]

open access: yesPeerJ, 2019
Hydrozoa medusae undergo blooms and seasonal fluctuations; however the drivers of such fluctuations are unknown. To understand how medusa populations fluctuate in response to seasonal factors such as temperature, salinity, dissolved oxygen, and ...

1H NMR Metabolic Profile of Scyphomedusa Rhizostoma pulmo (Scyphozoa, Cnidaria) in Female Gonads and Somatic Tissues: Preliminary Results

open access: yesMolecules, 2020
The Mediterranean basin is one of the regions heavily affected by jellyfish bloom phenomena, mainly due to the presence of scyphozoans, such as Rhizostoma pulmo.

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

open access: yesFrontiers 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.
