Phytopigments as biomarkers of selectivity in abyssal holothurians; interspecific differences in response to a changing food supply [PDF]

open access: yes, 2010
Holothurians dominate the abyssal megabenthos. They are key consumers and bioturbators of surficial sediment. Compounds essential for holothurian reproduction, such as carotenoids, are in short supply in the deep ocean.

Bacteria Associated Holothurians: the Key of Habitat Preference, Diet, and Functio [PDF]

open access: yes, 2011
An investigation of bacteria as holothurians's feed carried out from May until June 2006 in Medane Bay and Kombal Bay, Lombok, Indonesia. The aims of this study are to know whether holothurians eat bacteria, to observe that bacteria are the key for ...

Sea cucumbers reduce chromophoric dissolved organic matter in aquaculture tanks [PDF]

open access: yesPeerJ, 2018
Background Mono-specific aquaculture effluents contain high concentrations of nutrients and organic matter, which affect negatively the water quality of the recipient ecosystems. A fundamental feature of water quality is its transparency. The fraction of

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

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

SeeCucumbers: Using Deep Learning and Drone Imagery to Detect Sea Cucumbers on Coral Reef Flats

open access: yesDrones, 2021
Sea cucumbers (Holothuroidea or holothurians) are a valuable fishery and are also crucial nutrient recyclers, bioturbation agents, and hosts for many biotic associates. Their ecological impacts could be substantial given their high abundance in some reef

Molecular Networking-Based Analysis of Cytotoxic Saponins from Sea Cucumber Holothuria atra

open access: yesMarine Drugs, 2019
The saponin composition of a specimen of black sea cucumber, Holothuria atra collected in the Persian Gulf was studied by a combined approach including LC-MS/MS, Molecular Networking, pure compound isolation, and NMR spectroscopy. The saponin composition

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)

Bioeconomic modeling for a small-scale sea cucumber fishery in Yucatan, Mexico.

open access: yesPLoS ONE, 2018
Due to the heavy exploitation of holothurians over the last few decades, it is necessary to implement fishing regulations aimed at reversing this situation. Holothurians require specific regulations that take into account their biology and ecology. Their
