Autor: Stephanie L. Sargeant, Laura Weldon, Lyn C. Newton, Heather Macdonald, Ciara O’Leary, Mark D. Steer

Publikováno v: Environmental DNA, Vol 2, Iss 4, Pp 587-600 (2020)

The European eel, Anguilla anguilla, is classified as critically endangered by the IUCN. To protect what remains of the European eel population, accurate monitoring methods for this species are important. Environmental DNA (eDNA) techniques are gaini

Autor: Norm G. Hall, David J. Bird, Lyn C. Newton, Shaun J. Plenty, Richard M. Warwick, James R. Tweedley, Ian C. Potter, Peter Henderson

Publikováno v: Journal of Sea Research. 137:35-46

A 26-year time series of monthly samples from the water intake of a power station has been used to analyse the trends exhibited by number of species, total abundance, and composition of the mysids and caridean decapods in the inner Bristol Channel. D

Evidence for a population collapse of European eel (Anguilla anguilla) in the Bristol Channel

Autor: Peter Henderson, David J. Bird, Shaun J. Plenty, Lyn C. Newton

Publikováno v: Journal of the Marine Biological Association of the United Kingdom. 92:843-851

A 30-year study of the estuarine population of yellow eel, Anguilla anguilla, abundance in Bridgwater Bay, Somerset, UK, shows that the population number has collapsed. Since 1980, the decline has averaged 15% per year. The abundance of eel in 2009 i

Evidence for declining levels of heavy-metals in the Severn Estuary and Bristol Channel, U.K. and their spatial distribution in sediments

Autor: David J. Bird, Sabine Duquesne, Lyn C. Newton, Susan B. Marriott, L. Giusti, Hans-Joachim Stärk

Publikováno v: Environmental Pollution. 143:187-196

Levels of heavy-metals (Cd, Cu, Cr, Ni, Pb and Zn) in suspended particulate and in surface and subsurface sediments were determined at seven locations in the Severn Estuary and Bristol Channel. Sediment metal concentrations were highest at sites clos

Comparisons of fatty acid and stable isotope ratios in symbiotic and non-symbiotic brittlestars from Oban Bay, Scotland

Autor: Linda L. Handley, John A. Raven, Maeve Kelly, R. James Henderson, Kenneth D. Black, Charles M. Scrimgeour, Lyn C. Newton, J. Douglas McKenzie

Publikováno v: Journal of the Marine Biological Association of the United Kingdom. 80:311-320

The bed-forming brittlestars Ophiothrix fragilis, Ophiocomina nigra and Amphiura chiajei from Oban Bay, Scotland were studied using methods previously employed to study chemoautotrophic symbioses. Ophiothrix fragilis and A. chiajei both contain symbi

Brittlestars, Biomarkers and Beryl: Assessing the Toxicity of Oil-Based Drill Cuttings Using Laboratory, Mesocosm and Field Studies

Autor: Lyn C. Newton, J. Douglas McKenzie

Publikováno v: Chemistry and Ecology. 15:143-155

Effects of drill cuttings on burrowing brittlestars (Amphiura chiajei and A. filiformls) were compared at different levels of response, from acute laboratory experiments to chronic field studies. Acute toxicity tests showed that drill cuttings contai

To what extent are hepatic concentrations of heavy metals in Anguilla anguilla at a site in a contaminated estuary related to body size and age and reflected in the metallothionein concentrations?

Autor: Lyn C. Newton, Jeanette M. Rotchell, Norman G. Hall, S.A. Hesp, Ian C. Potter, David J. Bird

Publikováno v: Environmental pollution (Barking, Essex : 1987). 151(3)

We explored how hepatic [metal]s in Anguilla anguilla at a contaminated estuarine site are influenced by body size, age and season, and the extent that [Cu], [Cd] and [Zn]s are reflected in [metallothionein (MT)]s. Although each [metal] and [MT] incr

Concentrations of Cd, Zn and Cu in sediments and brown shrimp (Crangon crangon L.) from the Severn Estuary and Bristol Channel, UK

Autor: Lyn C. Newton, David J. Bird, Iain Weir, Caroline Culshaw

Publikováno v: Marine environmental research. 54(3-5)

Cd, Zn and Cu levels were determined in sediments and Crangon crangon from 9 sites in the Severn Estuary/Bristol Channel during winter 1999. Metal levels in both shrimp and sediments varied significantly between sites and were related to proximity of
