Spatiotemporal eDNA Monitoring of Marine Biodiversity in a Hyperurbanised Coastal Environment

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Using environmental DNA and a metabarcoding approach, we amplified and sequenced the cytochrome oxidase subunit I (COI) gene for invertebrates and the 16S rRNA gene for vertebrates. Our spatiotemporal analyses over a year and across four sites in Singapore revealed distinct communities between sites and timepoints for both the COI and 16S rRNA assays ...

Morphological and metabarcoding dietary analysis of the cunner wrasse (Tautogolabrus adspersus) revealed significant regional variation, with large overlap between its common prey species and biofouling animals living on salmonid sea cages

Journal of Fish Biology, Volume 107, Issue 1, Page 143-160, July 2025.
Abstract The stomach‐less cunner wrasse (Tautogolabrus adspersus) has been experimentally used as a biological control agent for salmon lice that infest Atlantic salmon (Salmo salar) and to remove biofouling inside sea cages. The cunner demonstrates a strong population structure, suggesting that its diet, and therefore its usefulness for biological ...

Biological activities of secondary metabolites of the order Zoanthids

Iranian South Medical Journal, 2015
The phylum Cnidaria is a large, diverse and ecologically important group of marine invertebrates, which produce powerful toxins and venoms. The number of marine natural product from cnidarians isolated from class Anthozoa.

Force-dependent discharge of nematocysts in the sea anemone Haliplanella luciae (Verrill)

Biology Open, 2012
Summary Sea anemones discharge cnidae (‘stinging capsules’ including nematocysts) to capture prey and to defend themselves. In the present study, we tested the relationship between the force of test probes striking feeding tentacles and discharge of ...

Coral Disease and Health Workshop: Coral Histopathology II [PDF]

, 2007
The health and continued existence of coral reef ecosystems are threatened by an increasing array of environmental and anthropogenic impacts. Coral disease is one of the prominent causes of increased mortality among reefs globally, particularly in the ...

Monopodial and Sympodial Growth Modes in the Colonial Graptolithina (Hemichordata, Pterobranchia)

Evolution &Development, Volume 27, Issue 2, June 2025.
ABSTRACT Two growth modes are recognized in colonial pterobranchs (Graptolithina): monopodial growth and sympodial growth. The earliest colonial Graptolithina likely developed through monopodial growth, a mode of colony formation well‐documented in the extant graptolite Rhabdopleura normani.

Revealing hidden sources of uncertainty in biodiversity trend assessments

Ecography, Volume 2025, Issue 5, May 2025.
Idiosyncratic decisions during the biodiversity trend assessment process may limit reproducibility, whilst ‘hidden' uncertainty due to collection bias, taxonomic incompleteness, and variable taxonomic resolution may limit the reliability of reported trends.

Notes on various British Anthozoa [PDF]

Journal of the Marine Biological Association of the United Kingdom, 1911
This species is described and figured by Gosse in his Actinologia Britannica, quoting its original discoverer Holdsworth, who obtained a number of specimens at the entrance of Dartmouth harbour from among the roots of Laminaria. In Section III of the Appendix, Gosse (p. 355) adds: “I have taken this at Torquay. It has also been found at Mizen Head, and
