Ulva species have been considered as ideal candidates for carbon capture, bioremediation and biofuel production. A career retrospective with former Celtic, Hibernian, Wigan, Newcastle defender Gary Caldwell I am especially interested in the role of algal-derived compounds in structuring aquatic food webs. Optimisation of productivity and lipid yields is required and the cost of biomass harvesting and dewatering must be significantly reduced. Using sodium dodecyl sulphate (SDS) as the surfactant, ciliates removal efficiencies of up to 86.6% were achieved from pure ciliates cultures at an SDS concentration of 40 mg L− 1. Underwater pile driving is typically undertaken during construction of offshore oil and gas platforms and wind farms and harbours. Zhang Y, Caldwell GS, Zealand AM, Sallis PJ.

The green seaweed Ulva is the causative genus behind nuisance green tides, but also has uses in the food and feed industries.

An adverse outcome pathway (AOP) mechanistically organizes the existing (eco)toxicological information from different levels of biological organization, similarly-acting stressors and phylogenetically conserved taxa into a linear pathway by connecting a molecular initiating event (MIE), a series of subsequent key events (KEs) and an adverse outcome... Microalgae technology has been used to capture CO2 from flue gases, but the current commercial algae open pond systems have many drawbacks such as expensive, infrastructure, high risk of contamination, large land and water requirements. In comparison with other animal venoms, fish venoms remain relatively understudied. However, the performance of the Malaysian aquaculture sector, particularly seaweed production, is poorly documented. Ocean acidification as a result of an enriched carbon dioxide atmosphere threatens ecosystem health and marine biodiversity. In a time when humanity is encountering one of its greatest challenges in the form of a global environmental crisis we look for solutions present within nature. Photosynthetic microorganisms are responsible for the habitable atmosphere that sustains the plethora of life on the planet. Fitzer SC, Caldwell GS, Clare AS, Upstill-Goddard RC, Bentley MG.

My research interests are broad ranging in relation to the marine environment, but with a Structural characterisation of the N-glycan moiety of the barnacle settlement-inducing protein complex (SIPC). After PhD studies at Menai Bridge under the supervision of Dr Graham Walker and the late Prof Denis Crisp CBE, FRS, Tony did a short postdoc before moving to the NERC Rocky Shore Surveillance Group here at Newcastle (Director Prof Bob Clark; 1983-88). © 2008-2021 ResearchGate GmbH. Diatoms produce an array of biologically-active metabolites, many of which have been attributed as a form of chemical defence and may offer potential as candidate marine drugs. The strains are in alphabetical order as listed in the Materials and Methods Section. A key aspect of my role is ensuring that Newcastle University policies on programme management and student support are implemented and leading on internal quality assurance and enhancement activities. This is especially true for that of the lesser Echiichthys vipera and greater weever fish Trachinus draco which, apart from the isolation of their unique venom cytolysins, trachinine and dracotoxin, respectively, remain relatively uncharacterised.

How to assess toxin ingestion and post-ingestion partitioning in zooplankton? Hazards and risks of ionizing radiation to aquatic organisms represent a potential problem in contaminated areas such as Chernobyl and Fukushima.

This study outlines the development of clay and ceramic-based living biocomposite materials under minimal moisture environments. Studies have, however, rarely considered the impact pollutants may have on grazer responses to algal toxins. He is theme leader for 'Ocean and Coastal Resources' within marineNewcastle and is stage 1 coordinator for Marine Science degree programmes. Toxicity of algal-derived aldehydes to two invertebrate species: Do heavy metal pollutants have a synergistic effect? This investigation aimed to evaluate the feasibility of potato processing waste (PPW) as a co-substrate for Chlorella vulgaris in batch biochemical methane potential (BMP) tests. Loop is the open research network that increases the discoverability and impact of researchers and their work. Here the validity of FA as a measure of larval fitness in the polychaete Nereis virens, and hence its value in ecotoxicological bioassays, was determined via a series of laboratory experiments. Despite the potential importance of these toxins in shaping aquatic ecosystems, marine studies to date have focused almost exclusively on planktonic calanoid copepods. We elucidate the role of the sediment reduction-oxidation (redox) regime in structuring benthic bacterial communities, having direct implications for bioremediation potential and deposit-feeder nutrition.
