Chronic pesticide exposure elicits a subtle carry-over effect on the metabolome of Aurelia coerulea ephyrae

open access: yes, 2021
Chemical pollutants, such as pesticides, often leach into aquatic environments and impact non-target organisms. Marine invertebrates have complex life cycles with multiple life-history stages.

Evidence of nitrification associated with globally distributed pelagic jellyfish

open access: yesLimnology and Oceanography, Volume 66, Issue 6, Page 2159-2173, June 2021., 2021
Abstract Often considered detrimental to the environment and human activities, jellyfish blooms are increasing in several coastal regions worldwide. Yet, the overall effect of these outbreaks on ecosystem productivity and structure are not fully understood. Here we provide evidence for a so far unanticipated role of jellyfish in marine nitrogen cycling.

Detecting community change in Arctic marine ecosystems using the temporal dynamics of environmental DNA

open access: yesEnvironmental DNA, Volume 3, Issue 3, Page 573-590, May 2021., 2021
Despite environmental DNA approach is an innovative biomonitoring tool, knowledge of temporal and spatial eDNA variation need to be improve to obtain reliable interpretation of the monitored communities. In this study, we investigated the temporal transition in eDNA of coastal marine communities between open‐water and ice‐covered periods in two Arctic ...

The importance of molecular characters when morphological variability hinders diagnosability: systematics of the moon jellyfish genus Aurelia (Cnidaria: Scyphozoa) [PDF]

open access: yesPeerJ, 2021
Cryptic species have been detected across Metazoa, and while no apparent morphological features distinguish them, it should not impede taxonomists from formal descriptions.

Trophic Transfer of Microplastics From Copepods to Jellyfish in the Marine Environment

open access: yesFrontiers in Environmental Science, 2020
Microplastics (MPs) can be ingested by marine organisms directly or indirectly through trophic transfer from contaminated prey. In the marine ecosystem, zooplankton are an important link between phytoplankton and higher trophic levels in the marine food ...

Microplastics ingestion in the ephyra stage of Aurelia sp. triggers acute and behavioral responses [PDF]

open access: yesEcotoxicology and Environmental Safety, 2020
For the first time, we report a correspondence between microplastics (MP) ingestion and ecotoxicological effects in gelatinous zooplankton (Cnidarian jellyfish). The ephyra stage of the jellyfish Aurelia sp. was exposed to both environmental and high concentrations of fluorescent 1-4 μm polyethylene MP (0.01-10 mg/L). After 24 and 48 h, MP accumulation,

Versatile aquarium for jellyfish: A rearing system for the biomass production of early life stages in flow-through or closed systems

open access: yesFrontiers in Marine Science, 2022
Interest in the rearing of jellyfish has grown exponentially over recent years due to their indisputable potential in a wide variety of uses and research. Here, we describe the design and operation of an effective modified kreisel aquarium that allows to

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.

Shorter, warmer winters may inhibit production of ephyrae in a population of the moon jellyfish Aurelia aurita

open access: yes, 2020
Scyphozoan jellyfish blooms display high interannual variability in terms of timing of appearance and size of the bloom. To understand the causes of this variability, the conditions experienced by the polyps prior to the production of ephyrae in the ...
