Environmental DNA Metabarcoding Reveals Distinct Spatial and Seasonal Patterns in Offshore Fish Communities in Eastern and Western Taiwan

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT The spatiotemporal distribution of marine organisms in Taiwan is influenced by the convergence of three major water masses and the East Asian monsoon system. However, most studies on marine fish communities have focused on larval stages due to sampling limitations.

Morphology, Swimming Performance and Propulsive Mode of Six Co-occurring Hydromedusae [PDF]

open access: yes, 2002
Jet propulsion, based on examples from the Hydrozoa, has served as a valuable model for swimming by medusae. However, cnidarian medusae span several taxonomic classes (collectively known as the Medusazoa) and represent a diverse array of morphologies and

CONDUCTION IN THE NERVE-FREE EPITHELIA OF SIPHONOPHORES [PDF]

open access: yesAmerican Zoologist, 1965
Optical and election microscopy leave little doubt that nerve and muscle fibers are completey absent from large stretches of the epithelium covering the swimming bells in siphonophores (Class Hydrozoa). Behavioral experiments show that these regions must conduct, and electrophysiological evidence of propagated depolarizations in the epithelial cells ...

Using stable isotopes to describe the trophic structure of gelatinous zooplankton across the deep pelagic

open access: yesLimnology and Oceanography, Volume 70, Issue 12, Page 3634-3649, December 2025.
Abstract Although gelatinous zooplankton are key members of marine ecosystems and food webs, their trophic ecology is poorly described across the deep pelagic. We used stable carbon (bulk tissue) and nitrogen (bulk tissue and amino acid) isotope analysis to estimate the trophic positions (TPs) of abundant gelatinous zooplankton (chaetognaths ...

Blackwater diving illuminates biodiversity and ecology of siphonophores in the Gulf Stream

open access: yesFrontiers in Marine Science
Siphonophores are gelatinous, colonial cnidarians distributed throughout the world’s oceans. They inhabit various water depths and are important predators in open waters, consuming multiple prey types. Siphonophore colonies are fragile and easily damaged

Metabarcoding dietary analysis of coral dwelling predatory fish demonstrates the minor contribution of coral mutualists to their highly partitioned, generalist diet [PDF]

open access: yesPeerJ, 2015
Understanding the role of predators in food webs can be challenging in highly diverse predator/prey systems composed of small cryptic species. DNA based dietary analysis can supplement predator removal experiments and provide high resolution for prey ...

Collection and estimation of zooplankton [PDF]

open access: yes, 2015
Zooplankters are the diverse, delicate and often very beautiful assemblages of animals that drift in the waters of the world oceans. The name zooplankton is derived from the Greek: Zoon, animal; planktos, wandering. They play a key role in the marine

Characterization of sound scattering layers in the Bay of Biscay using broadband acoustics, nets and video.

open access: yesPLoS ONE, 2019
Sound scattering layers (SSLs) are observed over a broad range of spatio-temporal scales and geographical areas. SSLs represent a large biomass, likely involved in the biological carbon pump and the structure of marine trophic webs.
