Unravelling Hidden Trophic Interactions Among Sea Urchin Juveniles and Macroinvertebrates by DNA Amplification. [PDF]

Mol Ecol
ABSTRACT Rocky reefs may shift between two distinct stable states: productive algal forests, characterised by high abundance and biodiversity of macrofauna, and impoverished barrens, dominated by overgrazing sea urchins. Barren states may persist despite the recovery of adult sea urchin predators, suggesting additional stabilising mechanisms.

Non-Invasive Underwater DNA Sampling Illuminates Red Sea Echinoderm Diversity. [PDF]

Mol Ecol Resour
ABSTRACT Species‐specific non‐invasive underwater DNA sampling remains largely understudied for marine invertebrates despite its potential to revolutionise biodiversity assessment of vulnerable species or fragile ecosystems. Comprehensive species‐specific DNA barcode databases are essential for accurate species identification and taxonomic assignment ...

Comparative Reproductive Biology of Deep-Sea Ophiuroids Inhabiting Polymetallic-Nodule Fields in the Clarion-Clipperton Fracture Zone

Frontiers in Marine Science, 2021
Deep-sea mining in the Pacific Clarion-Clipperton Fracture Zone (CCZ), a low-energy sedimentary habitat with polymetallic nodules, is expected to have considerable and long-lasting environmental impact.

Ophiotholia (Echinodermata: Ophiuroidea): A little-known deep-sea genus present in polymetallic nodule fields with the description of a new species

Frontiers in Marine Science, 2023
Introduction The Clarion Clipperton Zone (CCZ) in the Northeast Pacific Ocean holds the largest deposits of polymetallic nodules at abyssal depths. These nodules are rock formations containing valuable metals and minerals targeted for mining.

Development of two new sets of PCR primers for eDNA metabarcoding of brittle stars (Echinodermata, Ophiuroidea)

Metabarcoding and Metagenomics, 2023
Brittle stars (class Ophiuroidea) are marine invertebrates comprising approximately 2,100 extant species, and are considered to constitute the most diverse taxon of the phylum Echinodermata.
