Abstract. Antarctic krill (Euphausia superba) and salps are major macroplankton contributors to Southern Ocean food webs and krill are also fished commercially. Managing this fishery sustainably, against a backdrop of rapid regional climate change, requires information on distribution and time trends. Many data on the abundance of both taxa have been obtained from net sampling surveys since 1926, but much of this is stored in national archives, sometimes only in notebooks. In order to make these important data accessible we have collated available abundance data (numerical density, no. m−2) of postlarval E. superba and salp individual (multiple species, and whether …

Inhibitor Sbfi26 Suppresses The Malignant Progression Of Castration-Resistant Pc3-M Cells By Competitively Binding To Oncogenic Fabp5, W Al-Jameel, X Gou, Ss Forootan, Ms Al Fayi, Et Al
Peninsula Medical School
Castration resistant-prostate cancer is largely impervious to feather hormonal therapy and hence the outlook for patients is grim. Here we use an approach to attach the recently discovered Achilles heel. The experimental treatment established in this study is based on the recent discovery that it is the FABP5-PPAR?-VEGF signalling axis, rather than the androgen receptor pathway, played a dominant role in promoting the malignant progression of castration resistant prostate cancer cells. Treatments have been established in mice by suppressing the biological activity of FABP5 using a chemical inhibitor SBFI26. The inhibitor significantly suppressed the proliferation, migration, invasiveness and colony formation …

Identification of the heteroatom (nitrogen, sulfur, and oxygen)-containing compounds of petroleum is of key importance when considering industrial and environmental issues associated with crude oil production. The more commonly performed methods of crude oil fractionation are often insufficient in the extent to which they separate oils, not allowing defined “molecular” fractions to be obtained. Methods capable of performing a class type separation are uncommon and are often extensive and resource and time intensive. Here we report a method for the separation of crude oils into discrete compound classes. The method utilizes both ion exchange and normal phase chromatography to generate …

Gene Expression Profiling In Bladder Cancer Identifies Potential Therapeutic Targets, S Hussain, D Palmer, W-K Syn, J Sacco, Et Al
Peninsula Medical School
Despite advances in management, bladder cancer remains a major cause of cancer related complications. Characterisation of gene expression patterns in bladder cancer allows the identification of pathways involved in its pathogenesis, and may stimulate the development of novel therapies targeting these pathways. Between 2004 and 2005, cystoscopic bladder biopsies were obtained from 19 patients and 11 controls. These were subjected to whole transcript-based microarray analysis. Unsupervised hierarchical clustering was used to identify samples with similar expression profiles. Hypergeometric analysis was used to identify canonical pathways and curated networks having statistically significant enrichment of differentially expressed genes. Osteopontin (OPN) expression was …

School of Art, Design and Architecture
Multilayered 3D printing is already allowing architects, designers, and engineers to experiment with new design processes and new ways of production. A new field of research focuses on bio-inspired material finding and computer-aided fabrication processes. This article explores performance-driven design possibilities through a study of marine animals, specifically cephalopods, and then proposes a novel computational and fabrication model. This computation model, which is named “Pigment Skin,” imitates the cephalopods pigment distribution system to fit complex “host surfaces.” The study is divided into two parts; the first part focused on analysing the biological principles of Cephalopods skin and translating them to …

Reaction Times In Visual Search Can Be Explained By A Simple Model Of Neural Synchronization, Y Kazanovich, R Borisyuk
Reaction Times In Visual Search Can Be Explained By A Simple Model Of Neural Synchronization, Y Kazanovich, R Borisyuk
School of Engineering, Computing and Mathematics
We present an oscillatory neural network model that can account for reaction times in visual search experiments. The model consists of a central oscillator that represents the central executive of the attention system and a number of peripheral oscillators that represent objects in the display. The oscillators are described as generalized Kuramoto type oscillators with adapted parameters. An object is considered as being included in the focus of attention if the oscillator associated with this object is in-phase with the central oscillator. The probability for an object to be included in the focus of attention is determined by its saliency …

Towards Automating Underwater Measurement Of Fish Length: A Comparison Of Semi-Automatic And Manual Stereo–Video Measurements, F Shafait, Es Harvey, Mr Shortis, A Mian, Et Al
Towards Automating Underwater Measurement Of Fish Length: A Comparison Of Semi-Automatic And Manual Stereo–Video Measurements, F Shafait, Es Harvey, Mr Shortis, A Mian, Et Al
School of Engineering, Computing and Mathematics
Underwater stereo–video systems are widely used for counting and measuring fish in aquaculture, fisheries, and conservation management. Length measurements are generated from stereo–video recordings by a software operator using a mouse to locate the head and tail of a fish in synchronized pairs of images. This data can be used to compare spatial and temporal changes in the mean length and biomass or frequency distributions of populations of fishes. Since the early 1990s stereo–video has also been used for measuring the lengths of fish in aquaculture for quota and farm management. However, the costs of the equipment, software, the time, …

Auditory Multistability And Neurotransmitter Concentrations In The Human Brain, Hm Kondo, D Farkas, Sl Denham, T Asai, I Winkler
School of Psychology
Multistability in perception is a powerful tool for investigating sensory–perceptual transformations, because it produces dissociations between sensory inputs and subjective experience. Spontaneous switching between different perceptual objects occurs during prolonged listening to a sound sequence of tone triplets or repeated words (termed auditory streaming and verbal transformations, respectively). We used these examples of auditory multistability to examine to what extent neurochemical and cognitive factors influence the observed idiosyncratic patterns of switching between perceptual objects. The concentrations of glutamate–glutamine (Glx) and ?-aminobutyric acid (GABA) in brain regions were measured by magnetic resonance spectroscopy, while personality traits and executive functions were assessed …

Motivating Emotional Intelligence: A Reinforcement Sensitivity Theory (Rst) Perspective, Alison M. Bacon, Philip J. Corr
School of Psychology
Trait emotional intelligence (trait EI) is generally associated with positive outcomes and can inform clinical and social interventions. We investigated the sub-factors of trait EI: Wellbeing, Self-control, Emotionality, and Sociability, in the context of the reinforcement sensitivity theory (RST) of motivation. In Study 1, participants (N = 247) completed Carver and White’s (J Personal Soc Psychol 67:319–333; Carver, White, Journal of Personality and Social Psychology 67:319–333, 1994) BIS/BAS scales and a measure of trait EI. All EI sub-factors were positively associated with BAS Drive and negatively with BIS. Study 2 (N = 382) employed a new questionnaire based on revised …

School of Biological and Marine Sciences
Parasites are ubiquitous throughout nature and can have dramatic effects on their hosts. Although much is known about the pathology of parasites, the environmental factors influencing the distribution and abundance of parasites are poorly understood. Investigations into these factors could help predict the effect of parasites on the functioning of ecosystems. The limpet Patella vulgata is a key grazer on European rocky shores and is the first intermediate host for the trematode parasite, Echinostephilla patellae. This study investigated the spatial distribution of E. patellae in relation to P. vulgata at fourteen rocky shores around Ireland. Despite P. vulgata recruiting into …

Marine protected areas (MPAs) are a management tool used to respond to human-derived threats in marine ecosystems. Historically, MPAs have been established on an individual ad hoc basis, rather than through a systematic, planned process. However, high levels of functional and spatial connectivity within marine ecosystems have led to the suggestion that networks of MPAs provide greater ecological benefits than individual MPAs. Consequently, international policy has developed to consider broader spatial requirements for marine conservation, resulting in a number of international and regional agreements that require the establishment of ecologically coherent MPA networks. Existing MPAs are now being considered, retrospectively, …

School of Geography, Earth and Environmental Sciences
The capacity of bacteria for degrading dissolved organic nitrogen (DON) and remineralising ammonium is of importance for marine ecosystems, as nitrogen availability frequently limits productivity. Here, we assess the capacity of a widely distributed and metabolically versatile marine bacterium to degrade phytoplankton-derived dissolved organic carbon (DOC) and nitrogen. To achieve this, we lysed exponentially growing diatoms and used the derived dissolved organic matter (DOM) to support an axenic culture of Alteromonas sp.. Bacterial biomass (as particulate carbon and nitrogen) was monitored for 70 days while growth dynamics (cell count), DOM (DOC, DON) and dissolved nutrient concentrations were monitored for up …

Faunal Response To Sea-Level And Climate Change In A Short-Lived Seaway: Jurassic Of The Western Interior, Usa, S Danise, Sm Holland
School of Geography, Earth and Environmental Sciences
Understanding how regional ecosystems respond to sea-level and environmental perturbations is a main challenge in palaeoecology. Here we use quantitative abundance estimates, integrated within a sequence stratigraphic and environmental framework, to reconstruct benthic community changes through the 13 myr history of the Jurassic Sundance Seaway in the western United States. Sundance Seaway communities are notable for their low richness and high dominance relative to most areas globally in the Jurassic, and this probably reflects steep temperature and salinity gradients along the 2000 km length of the Seaway that hindered colonization of species from the open ocean. Ordination of samples shows …
Ecological Risk Assessments To Guide Decision-Making: Methodology Matters, Gj Piet, Am Knights, Rh Jongbloed, Et Al
Ecological Risk Assessments To Guide Decision-Making: Methodology Matters, Gj Piet, Am Knights, Rh Jongbloed, Et Al
School of Geography, Earth and Environmental Sciences
Ecological risk assessment is often applied to guide the decision-making process that underpins ecosystem-based management and prioritisation of risk factors for management. Several studies have recently used ecological risk assessment approaches to identify risk factors of greatest concern, but rarely are the underlying methodological decisions discussed in terms of the effect that those decisions have on the outcome of the assessment and ultimately, how that affects prioritisation of risk factors for management. This study therefore evaluates the effect of methodological decisions involving (1) the choice and definition of risk factors, and (2) the calculation of risk scores, providing, where possible, …
