ABSTRACT: Underwater visual census (UVC) techniques using SCUBA have been rarely employed to evaluate fish diversity associated with oil and gas offshore platforms. These techniques can be particularly useful since traditional methods such as fishing surveys are not able to give information about fishes ...
A novel defensin antimicrobial peptide gene was identified in Atlantic cod, Gadus morhua. This three exon/two intron defensin gene codes for a peptide precursor consisting of two domains: a signal peptide of 26 amino acids and a mature peptide of 40 residues. The mature cod defensin has six conserved ...
ABSTRACT This paper reports the experiences of SLP Energy as a project developer in planning, procuring and managing the environmental, geophysical and geotechnical site investigations for Sheringham Shoal offshore wind farm. The paper examines the lessons that have been learned by SLP and suggests ...
ABSTRACT In the UK, statutory control of the disposal of wastes to sea from ships is provided by the Food and Environment Protection Act (Part II,1985), and monitoring of the environmental effects of licensed activity has been conducted by the Centre for Environment, Fisheries and Aquaculture Science ...
ABSTRACT Artificial reefs are used around the world to promote fisheries They range from very simple to complex structures using a wide variety of materials to recreate some or all aspects of natural reefs, providing shelter from currents and predators, food and breeding sites for fish and other marine ...
ABSTRACT Low cost remotely operated vehicles (ROV), 1.e costing under £ 100k, have become a relatively common tool for work in the marine environment. A survey conducted in 1992 identified over 800 such vehicles in use, however the vast majority are used for inspection/engineering tasks and only a ...
The feasibility study on the application of advanced robotics (AR) to underwater work was undertaken by UEG, the Offshore and Underwater Engineering Group of CIRIA, between May 1986 and July 1987 on behalf of the UK Department of Trade and Industry (DTI) It was one of a number of DTI studies in separate ...
Genes involved in sex determination and differentiation have been identified in mice, humans, chickens, reptiles, amphibians and teleost fishes. However, little is known of their functional conservation, and it is unclear whether there is a common set of genes shared by all vertebrates. Coelacanths, ...
Introduction We examined patterns of genetic divergence in 26 Mediterranean populations of the semi-terrestrial beachflea Orchestia montagui using mitochondrial (cytochrome oxidase subunit I), microsatellite (eight loci) and allozymic data. The species typically forms large populations within heaps ...
Background There is evidence to support the use of supplementation with long-chain omega-3 polyunsaturated fatty acids (LCn-3PUFA) from oily fish or fish oil for the treatment of various inflammatory diseases such as rheumatoid arthritis. Chronic obstructive pulmonary disease (COPD) is a progressive, ...
The present study was carried out on the seasonal abundance and diversity of zooplankton in a semi- intensive prawn farm of Bagerhat district from July to December, 2008. Plankton samples were collected by conical shaped monofilament nylon net (Plankton net) and Lugol’s solution was used for preservation. ...
In response to endoplasmic reticulum (ER) stress, the signaling pathway termed unfolded protein response (UPR) is activated. To investigate the role of UPR in Litopenaeus vannamei immunity, the activating transcription factor 4 (designated as LvATF4) which belonged to a branch of the UPR, the [protein ...
In systems with several effectors, the results of dose-response (DR) experiments are usually assessed by checking them against two hypotheses: independent action (IA) and concentration addition (CA). Both are useful simplifications, but do not represent the only possible responses, and avoid to a large ...
The recent invasion of the red alga Heterosiphonia japonica in the western North Atlantic Ocean has provided a unique opportunity to study invasion dynamics across a biogeographical barrier. Native to the western North Pacific Ocean, initial collections in 2007 and 2009 restricted the western North ...
Background and objectives Inuit populations may be at increased risk for experiencing poor nutrition or hunger due to limited access and availability to food. The prevalence and correlates of parental perceptions of hunger among a nationally representative sample of Inuit children in Canada have not ...
Age estimates, typically determined by counting periodic growth increments in calcified structures of vertebrates, are the basis of population dynamics models used for managing exploited or threatened species. In fisheries research, the use of otolith growth rings as an indicator of fish age has increased ...
The predatory marine gastropod Dicathais orbita has been the subject of a significant amount of biological and chemical research over the past five decades. Natural products research on D. orbita includes the isolation and identification of brominated indoles and choline esters as precursors of Tyrian ...
Background Strongylocentrotid sea urchins have a long tradition as model organisms for studying many fundamental processes in biology including fertilization, embryology, development and genome regulation but the phylogenetic relationships of the group remain largely unresolved. Although the differing ...
Bivalves play vital roles in marine, brackish, freshwater and terrestrial habitats. In recent years, these ecosystems have become affected through anthropogenic activities. The ecological success of marine bivalves is based on the ability to modify their physiological functions in response to environmental ...
For the rapid production of influenza vaccine antigens in unlimited quantities, a transition from conventional egg-based production to cell-based and recombinant systems is required. The need for higher-yield, lower-cost, and faster production processes is critical to provide adequate supplies of influenza ...
