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 ...

Hydrozoans, scyphozoans, larvaceans and ctenophores observed in situ at hadal depths
Journal of Plankton Research, 2021 Hydrozoa, Scyphozoa, Larvacea (Appendicularia) and Ctenophora are not typically associated with hadal communities. Here, we report observations of these groups based on 136 benthic camera lander deployments that spanned all five oceans, encompassing 14

Plankton and Benthos Research, 2021 : ROV dive surveys were carried out inside and outside the Sumisu Caldera, located in the Izu-Bonin Arc. The caldera is hydrothermally active and nourishes a unique chemosynthetic ecosystem, which includes Bathymo-diolus mussel beds and vestimentiferan ...

Medusan Morphospace: Phylogenetic Constraints, Biomechanical Solutions, and Ecological Consequences [PDF]
, 2008 Medusae were the earliest animals to evolve muscle-powered swimming in the seas. Although medusae have achieved diverse and prominent ecological roles throughout the world\u27s oceans, we argue that the primitive organization of cnidarian muscle tissue ...

The Phylum Cnidaria: A Review of Phylogenetic Patterns and Diversity 300 Years After Linnaeus [PDF]
, 2007 Systema Naturae includes representatives of every major lineage of the animal phylum Cnidaria. However, Linnaeus did not classify the members of the phylum as is now done, and the diversity of the group is not well represented.

Questioning the rise of gelatinous zooplankton in the World's oceans [PDF]
, 2012 During the past several decades, high numbers of gelatinous zooplankton species have been reported in many estuarine and coastal ecosystems. Coupled with media-driven public perception, a paradigm has evolved in which the global ocean ecosystems are ...

Are jellyfish increasing in response to ocean acidification? [PDF]
, 2008 Ocean acidification may negatively affect calcifying plankton, opening ecological space for noncalcifying species. Recently, a study of climate-forcing of jellyfish reported the first analysis suggesting that there were more jellyfish (generally ...

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 ...
