The complete mitochondrial genome and phylogenetic analysis of hydrozoan jellyfish Eirene ceylonensis (Cnidaria, Hydrozoa, Eirenidae) in the coastal sea of Qinhuangdao, China. [PDF]

open access: yesMitochondrial DNA B Resour, 2023
Eirene ceylonensis, a hydrozoan jellyfish species with a complex polymorphic life cycle, is widely distributed in the Chinese coastal sea. In this study, we conducted sequencing and analysis of the first complete mitochondrial genome of E.

The mitochondrial genome of Monoserius pennarius (Linnaeus, 1758) from the East China Sea. [PDF]

open access: yesMitochondrial DNA B Resour
The species Monoserius pennarius (Linnaeus, 1758), is particularly abundant in the tropical Indo-West Pacific east of Sri Lanka, yet very limited genetic information exists for this species. Here, we report the assembled-linear mitochondrial genome of M.

Ocean Acidification Alters the Predator – Prey Relationship Between Hydrozoa and Fish Larvae

open access: yesFrontiers in Marine Science, 2022
Anthropogenic CO2 emissions cause a drop in seawater pH and shift the inorganic carbon speciation. Collectively, the term ocean acidification (OA) summarizes these changes. Few studies have examined OA effects on predatory plankton, e.g.

Complete mitochondrial genome of the hydrozoan jellyfish Blackfordia virginica Mayer, 1910 (Cnidaria; Hydrozoa; Leptothecata) with phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2021
In this study, we analyzed the complete mitochondrial genome of the hydrozoan jellyfish Blackfordia virginica. The genome was a linear form (15,109 bp long, 73.6% AT), including 13 protein-coding genes (cox2, atp8, atp6, cox3, nad2, nad5, nad6, nad3 ...

The mitochondrial genome of Nemalecium lighti (Hydrozoa, Leptothecata)

open access: yesMitochondrial DNA. Part B. Resources, 2021
The hydrozoan species Nemalecium lighti (Hargitt, 1924) is widely distributed in tropical marine waters around the world. Here we report the complete linear mitochondrial genome of N. lighti from Sint Eustatius (Lesser Antilles). The mitochondrial genome

New species of Eirenidae (Hydrozoa: Leptothecata) from the Amazonian coast (northern Brazil)

open access: yesScientia Marina, 2020
Two new Eirenidae medusae species were collected on the Amazonian coast, Eutima marajoara n. sp. and Helgicirrha angelicae n. sp. The former differs from other species of the genus by the gonads extending along almost the entire length of the ...

Freshwater hydrozoan blooms alter activity and behaviour of territorial cichlids in Lake Tanganyika [PDF]

open access: yesRoyal Society Open Science, 2019
Blooms of gelatinous zooplankton can represent dramatic environmental perturbations for aquatic ecosystems. Yet, we still know little about how blooms impact fitness-related behaviours of fish caught within their areas of effect, especially for ...

Seasonal Changes in Vertical Distribution and Population Structure of the Dominant Hydrozoan Aglantha digitale in the Western Subarctic Pacific

open access: yesOceans, 2023
Hydrozoans are numerically dominant taxa in gelatinous zooplankton communities of the worldwide oceans and play an energy transfer role connecting primary producers and higher trophic level organisms. In the western subarctic Pacific, St.

Towards understanding the phylogenetic history of Hydrozoa: Hypothesis testing with 18S gene sequence data

open access: yesScientia Marina, 2000
Although systematic treatments of Hydrozoa have been notoriously difficult, a great deal of useful information on morphologies and life histories has steadily accumulated. From the assimilation of this information, numerous hypotheses of the phylogenetic
