Environmental DNA surveys detect distinct metazoan communities across abyssal plains and seamounts in the western Clarion Clipperton Zone. [PDF]

Mol Ecol, 2020
Abstract The deep seafloor serves as a reservoir of biodiversity in the global ocean, with >80% of invertebrates at abyssal depths still undescribed. These diverse and remote deep‐sea communities are critically under‐sampled and increasingly threatened by anthropogenic impacts, including future polymetallic nodule mining.

Three major mesoplanktonic communities resolved by in situ imaging in the upper 500 m of the global ocean

Global Ecology and Biogeography, Volume 32, Issue 11, Page 1991-2005, November 2023., 2023
Abstract Aim The distribution of mesoplankton communities has been poorly studied at global scale, especially from in situ instruments. This study aims to (1) describe the global distribution of mesoplankton communities in relation to their environment and (2) assess the ability of various environmental‐based ocean regionalizations to explain the ...

Integrating siphonophores into marine food‐web ecology

Limnology and Oceanography Letters, Volume 7, Issue 2, Page 81-95, April 2022., 2022
Abstract Siphonophores are a clade of understudied colonial hydrozoans (Cnidaria) that are abundant predators in oceanic ecosystems, with species present across the water column. We (1) synthesize current knowledge about siphonophore trophic ecology and predator–prey interactions, (2) analyze siphonophore‐prey networks to compare food‐web topology ...

Tackling the jelly web: Trophic ecology of gelatinous zooplankton in oceanic food webs of the eastern tropical Atlantic assessed by stable isotope analysis

Limnology and Oceanography, Volume 66, Issue 2, Page 289-305, February 2021., 2021
Abstract Gelatinous zooplankton can be present in high biomass and taxonomic diversity in planktonic oceanic food webs, yet the trophic structuring and importance of this “jelly web” remain incompletely understood. To address this knowledge gap, we provide a holistic trophic characterization of a jelly web in the eastern tropical Atlantic, based on ...

Narcomedusae Haeckel 1879

, 2021
Order Narcomedusae Remarks: The families of the Narcomedusae have recently been reorganized by Lindsay et al. (2017) using DNA data. Bentlage et al. (2018) added more sequences. The 16S sequences of these studies and the ones from the present study were combined to get a maximum likelihood tree (Fig. 48).

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

Scientia 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

The perils of online biogeographic databases: a case study with the ‘monospecific’ genus Aegina (Cnidaria, Hydrozoa, Narcomedusae) [PDF]

Marine Biology Research, 2017
ABSTRACTOnline biogeographic databases are increasingly being used as data sources for scientific papers and reports, for example, to characterize global patterns and predictors of marine biodiversity and to identify areas of ecological significance in the open oceans and deep seas.

Estructura poblacional del zooplancton gelatinoso en el mar ecuatoriano

Revista Científica de Ciencias Naturales y Ambientales, 2019
El presente estudio analiza la composición y distribución del zooplancton gelatinoso en el mar ecuatoriano desde Julio 2017 hasta Abril 2018. Se dividió el perfil costero en dos zonas: la ZI abarcó la provincia de Esmeraldas hasta la parte norte de la ...

Improving plankton image classification using context metadata

Limnology and Oceanography: Methods, Volume 17, Issue 8, Page 439-461, August 2019., 2019
Abstract Advances in both hardware and software are enabling rapid proliferation of in situ plankton imaging methods, requiring more effective machine learning approaches to image classification. Deep Learning methods, such as convolutional neural networks (CNNs), show marked improvement over traditional feature‐based supervised machine learning ...

Seismic Disturbance, Productivity and Depth Shape Hadal Benthic Habitats and Biodiversity in the Japan, Ryukyu and Izu‐Ogasawara Trenches (Northwest Pacific Ocean)

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim This study characterises benthic habitats and associated biodiversity in three Japanese subduction trenches, and explores the effects of trench‐specific differences in large‐scale seismic events, disturbance and productivity regimes on habitat structure and assemblage composition.
