Has Phytodetritus Processing by an Abyssal Soft-Sediment Community Recovered 26 Years after an Experimental Disturbance? [PDF]

open access: yesFrontiers in Marine Science, 2018
The potential harvest of polymetallic nodules will heavily impact the abyssal, soft sediment ecosystem by removing sediment, hard substrate, and associated fauna inside mined areas. It is therefore important to know whether the ecosystem can recover from

Underwater Holothurian Target-Detection Algorithm Based on Improved CenterNet and Scene Feature Fusion [PDF]

open access: yesSensors, 2022
Aiming at the common problems, such as noise pollution, low contrast, and color distortion in underwater images, and the characteristics of holothurian recognition, such as morphological ambiguity, high similarity with the background, and coexistence of ...

Metabolic rates are significantly lower in abyssal Holothuroidea than in shallow-water Holothuroidea [PDF]

open access: yesRoyal Society Open Science, 2018
Recent analyses of metabolic rates in fishes, echinoderms, crustaceans and cephalopods have concluded that bathymetric declines in temperature- and mass-normalized metabolic rate do not result from resource-limitation (e.g. oxygen or food/chemical energy)

Quorum Quenching Strains Isolated from the Microbiota of Sea Anemones and Holothurians Attenuate Vibriocorallilyticus Virulence Factors and Reduce Mortality in Artemiasalina [PDF]

open access: yesMicroorganisms, 2022
Interference with quorum-sensing (QS) intercellular communication systems by the enzymatic disruption of N-acylhomoserine lactones (AHLs) in Gram-negative bacteria has become a promising strategy to fight bacterial infections.

Characterization and phylogenetic analysis of the complete mitochondrial genome of Benthodytes gosarsi Gebruk 2008 (echinodermata: holothuroidea: elasipodida) from deep-sea environments [PDF]

open access: yesMitochondrial DNA. Part B. Resources
Deep-sea organisms exhibit remarkable adaptations to extreme environmental conditions. It is important to elucidate the survival mechanisms of deep-sea life by exploring their genetic characteristics and origins.

Toxic properties of holothurian’s triterpene glycosides

open access: yesВестник войск РХБ защиты, 2023
Holothurians (or sea cucumbers) are echinoderms and are found in all areas of the world oceans. These animals produce special low-molecular metabolites - triterpene glycosides, which are a means of chemical protection of holothurians from predators.

Highly rearranged gene orders and rapid evolutionary rates in the mitochondrial genomes of Apodida (Echinodermata: Holothuroidea)

open access: yesFrontiers in Marine Science, 2023
Mitochondrial genome (mitogenome) is a frequently-used tool for phylogenetic and evolutionary studies among metazoans, however, it was still poorly represented in some invertebrate groups, including holothurians. Apodida is one of the most ancient orders

Current Progress in Lipidomics of Marine Invertebrates

open access: yesMarine Drugs, 2021
Marine invertebrates are a paraphyletic group that comprises more than 90% of all marine animal species. Lipids form the structural basis of cell membranes, are utilized as an energy reserve by all marine invertebrates, and are, therefore, considered ...

A Review of Factors Influencing the Seagrass-Sea Cucumber Association in Tropical Seagrass Meadows

open access: yesFrontiers in Marine Science, 2021
In the tropical ecosystem, sea cucumbers are associated with seagrass meadows in various ways, often forming a network of ecological interactions. From this myriad of interactions, the trophic relationship between the seagrasses and sea cucumbers has ...
