Biosynthesis of Polyunsaturated Fatty Acids in Sea Urchins: Molecular and Functional Characterisation of Three Fatty Acyl Desaturases from Paracentrotus lividus (Lamark 1816).

open access: yesPLoS ONE, 2017
Sea urchins are broadly recognised as a delicacy and their quality as food for humans is highly influenced by their diet. Lipids in general and the long-chain polyunsaturated fatty acids (LC-PUFA) in particular, are essential nutrients that determine not

High fitness areas drive the aggregation of the sea urchin Mesocentrotus nudus [PDF]

open access: yesPeerJ, 2022
Sea urchin aggregation is a common phenomenon in coastlines. However, it remains controversial whether sea urchins form resource aggregations or behavioral aggregations in a non-spawning season.

Sea urchin granuloma [PDF]

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 2006
Injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in humans. The phylum Echinoderma include more than 6000 species of starfish, sea urchins, sand dollars, and sea cucumbers some of which have been found responsible for injuries to humans. Initial injuries by sea urchins are associated with trauma and envenomation,

Structure and function of sea urchin neuropeptides [PDF]

open access: yes, 2010
PhDThe subject of this thesis is the identification and functional characterization of sea urchin neuropeptides. Neuropeptides are important mediators of neural signalling in all known animals with a nervous system, including bilaterians, ctenophorans ...

Comparative morpho‐physiological aspects and transcriptomics of the gonads from wild caught and enhanced green sea urchin (Strongylocentrotus droebachiensis)

open access: yesAquaculture, Fish and Fisheries, 2022
There is a growing interest in sea urchin roe enhancement around the world, but relatively little is known about the physical differences between enhanced and wild sea urchin roe and the causes of any differences.

Alterations in sea urchin (Mesocentrotus nudus) microbiota and their potential contributions to host according to barren severity

open access: yesnpj Biofilms and Microbiomes, 2023
Sea urchins are biotic factors driving the decline of kelp forests in marine ecosystems. However, few studies have analyzed the microbiota of surviving sea urchins in barren regions with scarce diet resources.

Contamination of sea urchin Mesocentrotus nudus by radiocesium released during the Fukushima Daiichi Nuclear Power Plant accident.

open access: yesPLoS ONE, 2022
Countless marine organisms were polluted with radioactive materials that were dispersed when the Fukushima Daiichi Nuclear Power Plant (FDNPP) was damaged in 2011 by the Great East Japan Earthquake.

Distinct realized physiologies in green sea urchin (Strongylocentrotus droebachiensis) populations from barren and kelp habitats

open access: yesFACETS, 2022
Overgrazing of habitat-forming kelps by sea urchins is reshaping reef seascapes in many temperate regions. Loss of kelp, in particular as a food source, may alter individual consumer physiology, which in turn may impair their ability to respond to ...

Characteristic of Microplastic on Coral Reef Sediment and Sea Urchin (Diadema sp.) in Tidung Island, Jakarta Bay, Indonesia

open access: yesIlmu Kelautan, 2023
Microplastics are recognized as common contaminants of coral ecosystem in Tidung Island, affecting both sediment and sea urchins residing in this environment. Therefore, this study aimed to determine the characteristics of microplastics found in sediment,

Urchin Searchin’: Red urchins and drift kelp found at 284 m in the mesophotic zone

open access: yesCiencias Marinas, 2020
Red sea urchins (Mesocentrotus franciscanus) are kelp-associated ecosystem engineers found in rocky habitats throughout the North Pacific from Baja California, Mexico, to Japan.
