Broad Spectrum Artificial Light At Night Increases The Conspicuousness Of Camouflaged Prey, Oak Mcmahon, Tim Smyth, Thomas W. Davies
Broad Spectrum Artificial Light At Night Increases The Conspicuousness Of Camouflaged Prey, Oak Mcmahon, Tim Smyth, Thomas W. Davies
School of Biological and Marine Sciences
1. The growing global prevalence of energy efficient broad spectrum lighting threatens to disrupt an array of visually guided ecological processes. Broad spectrum lighting likely better enables the discrimination of colour, yet it is potential to increase the conspicuousness of camouflaged prey at night remains little explored.2. Using a well-established visual model, we quantified the impacts of four spectrally distinct narrow and broad spectrum lighting technologies on the conspicuousness of three different polymorphic colour variations of intertidal littorinid snail, as viewed by three model predators.3. Modern broad spectrum lighting technologies increased the conspicuousness of prey compared to 20th-century narrow spectrum …

Using Expert-Elicitation To Deliver Biodiversity Monitoring Priorities On A Mediterranean Island, J Peyton, M Hadjistylli, I Tziortzis, Et Al
School of Biological and Marine Sciences
Biodiversity monitoring plays an essential role in tracking changes in ecosystems, species distributions and abundances across the globe. Data collected through both structured and unstructured biodiversity recording can inform conservation measures designed to reduce, prevent, and reverse declines in valued biodiversity of many types. However, given that resources for biodiversity monitoring are limited, it is important that funding bodies prioritise investments relative to the requirements in any given region. We addressed this prioritisation requirement for a biodiverse Mediterranean island (Cyprus) using a three-stage process of expert-elicitation. This resulted in a structured list of twenty biodiversity monitoring needs; specifically, a hierarchy …

The offshore wind energy sector has rapidly expanded over the past two decades, providing a renewable energy solution for coastal nations. Sector development has been led in Europe, but is growing globally. Most developments to date have been in well-mixed, i.e., unstratified, shallow-waters near to shore. Sector growth is, for the first time, pushing developments to deep water, into a brand new environment: seasonally stratified shelf seas. Seasonally stratified shelf seas, where water density varies with depth, have a disproportionately key role in primary production, marine ecosystem and biogeochemical cycling. Infrastructure will directly mix stratified shelf seas. The magnitude of …

Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best …
Sustainable Manufacture Of Natural Fibre Reinforced Epoxy Resin Composites With Coupling Agent In The Hardener, Michelena A Hernandez, John Summerscales, Jasper Graham-Jones, Wayne Hall
Sustainable Manufacture Of Natural Fibre Reinforced Epoxy Resin Composites With Coupling Agent In The Hardener, Michelena A Hernandez, John Summerscales, Jasper Graham-Jones, Wayne Hall
School of Engineering, Computing and Mathematics
Lignocellulosic natural fibres are hydrophilic, while many matrix systems for composites are hydrophobic. The achievement of good mechanical properties for natural fibre-reinforced polymer (NFRP) matrix composites relies on good fibre-to-matrix bonding at the interface. The reinforcement is normally coated with an amphiphilic coupling agent to promote a strong interface. A novel alternative approach is to dissolve the coupling agent in the hardener for the resin before creating the stoichiometric mix with the base epoxy resin. During composite manufacture, the hydrophilic (polar) end of the coupling agent migrates to surfaces (internal interfaces) and bonds to the fibres. The hydrophobic (non-polar) end …
An Efficient Method For Nested High-Resolution Ocean Modelling Incorporating A Data Assimilation Technique, Georgy I. Shapiro
An Efficient Method For Nested High-Resolution Ocean Modelling Incorporating A Data Assimilation Technique, Georgy I. Shapiro
School of Biological and Marine Sciences
A simple and computationally efficient method is presented for creating a high-resolution regional (child) model nested within a coarse-resolution, good-quality data-assimilating (parent) model. The method, named Nesting with Downscaling and Data Assimilation (NDA), reduces bias and root mean square errors (RMSE) of the child model and does not allow the child model to drift from reality. Usually coarser resolution models, e.g., global scale, are used to provide boundary conditions for the nested child model. The basic idea of the NDA method is to use a complete 3D set of output data from the parent model using a process which is …

Subaerial Volcanism Is A Potentially Major Contributor To Oceanic Iron And Manganese Cycles, Jack Longman, Martin R. Palmer, Thomas M. Gernon, Hayley R. Manners, Morgan T. Jones
Subaerial Volcanism Is A Potentially Major Contributor To Oceanic Iron And Manganese Cycles, Jack Longman, Martin R. Palmer, Thomas M. Gernon, Hayley R. Manners, Morgan T. Jones
School of Geography, Earth and Environmental Sciences
Surface ocean availability of the micronutrients iron and manganese influences primary productivity and carbon cycling in the ocean. Volcanic ash is rich in iron and manganese, but the global supply of these nutrients to the oceans via ash deposition is poorly constrained. Here, we use marine sediment-hosted ash composition data from ten volcanic regions, and subaerial volcanic eruption volumes, to estimate global ash-driven nutrient fluxes. Using Monte Carlo simulations, we estimate average fluxes of dissolved Iron and Manganese from volcanic sources to be between 50 and 500 (median 180) and 0.6 and 3.2 (median 1.3) Gmol yr−1, respectively. Much of …

School of Biological and Marine Sciences
Two sulphur-oxidizing, chemolithoautotrophic aerobes were isolated from the chemocline of an anchialine sinkhole located within the Weeki Wachee River of Florida. Gram-stain-negative cells of both strains were motile, chemotactic rods. Phylogenetic analysis of the 16S rRNA gene and predicted amino acid sequences of ribosomal proteins, average nucleotide identities, and alignment fractions suggest the strains HH1T and HH3T represent novel species belonging to the genus Thiomicrorhabdus. The genome G+C fraction of HH1T is 47.8 mol% with a genome length of 2.61 Mb, whereas HH3T has a G+C fraction of 52.4 mol% and 2.49 Mb genome length. Major fatty acids of the …

Sublethal Injuries And Physical Abnormalities In Maldives Manta Rays, Mobula Alfredi And Mobula Birostris, Elspeth M. Strike, Joanna L. Harris, Kirsty L. Ballard, Julie P. Hawkins, Jennifer Crockett, Guy M.W. Stevens
School of Biological and Marine Sciences
Manta ray populations worldwide are vulnerable to sublethal injuries resulting from human activities, e.g., entanglement in fishing line and boat strikes, which have the potential to impact an individual’s health, fitness, and behaviour. Sublethal injuries and physical abnormalities also occur naturally from predation events, deformity, parasites, and disease. To determine the type and frequency of anthropogenic and natural originated injury events affecting Mobula alfredi and M. birostris in the Maldives, we examined data from the Manta Trust’s Maldivian Manta Ray Project (MMRP) database, which contains 73,638 photo-identification (photo-ID) sightings of the two manta ray species from 1987 to 2019.

Genetically Based Adaptive Trait Shifts At An Expanding Mangrove Range Margin, John Paul Kennedy, Giles N. Johnson, Richard F. Preziosi, Jennifer K. Rowntree
School of Biological and Marine Sciences
AbstractNeotropical black mangrove (Avicennia germinans) is expanding poleward into temperate salt marsh along Atlantic Florida, USA, with field evidence of trait shifts consistent with greater cold tolerance within range margin populations. However, whether these shifts have a genetic basis remains unanswered. To address this gap, we measured multiple phenotypic traits of twenty A. germinans maternal cohorts from areas in both the Atlantic Florida range core and margin in a 2-year greenhouse common garden with annual temperatures analogous to range margin conditions. Compared to those from the range core, range margin cohorts survived in greater numbers, established (i.e., produced first true …
Aptamer Functionalisation Of Back-Gated Graphene Field Effect Transistors For Pb2+ Sensing, S Awan
Aptamer Functionalisation Of Back-Gated Graphene Field Effect Transistors For Pb2+ Sensing, S Awan
School of Engineering, Computing and Mathematics
We discuss the development of aptamer functionalized, back-gated, graphene field effect transistor (GFET) biosensors for the targeted detection of Lead (Pb2+) ions. The widespread existence of the heavy metal Pb2+ in the environment is a severe threat to the health of humans. It is a neurotoxin that accumulates over time in the body restricting the cognitive, behavioral and psychological development of children along with causing irreversible harm to the human fetus. New biosensors which allow for the rapid, sensitive and low-cost detection of Pb2+ are required to monitor this toxicant in water sources worldwide. The GFET devices were fabricated using …

On The Importance Of The Newborn Stage When Learning Patterns With The Spatial Pooler, D Dobric, A Pech, B Ghita, T Wennekers
School of Engineering, Computing and Mathematics
Hierarchical Temporal Memory (HTM-CLA) - Spatial Pooler (SP) is a Cortical Learning Algorithm for learning inspired by the neocortex. It is designed to learn the spatial pattern by generating the Sparse Distributed Representation code (SDR) of the input. It encodes the set of active input neurons as SDR defined by the set of active neurons organized in groups called mini-columns. This paper provides additional findings extending the previous work, that demonstrates how and why the Spatial Pooler forgets learned SDRs in the training progress. The previous work introduced the newborn stage of the algorithm, which takes a control of the …

School of Biological and Marine Sciences
The chytrids (phylum Chytridiomycota) are a major fungal lineage of ecological and evolutionary importance. Despite their importance, many fundamental aspects of chytrid developmental and cell biology remain poorly understood. To address these knowledge gaps, we combined quantitative volume electron microscopy and comparative transcriptome profiling to create an ‘atlas’ of the cellular and molecular basis of the chytrid life cycle, using the model chytrid Rhizoclosmatium globosum. From our developmental atlas, we describe the transition from the transcriptionally inactive free-swimming zoospore to the more biologically complex germling, and show that lipid processing is multifaceted and dynamic throughout the life cycle. We demonstrate …

Measuring brain activity through Electroencephalogram (EEG) analysis for eye state prediction has attracted attention from machine learning researchers. There have been many methods for EEG analysis using supervised and unsupervised machine learning techniques. The tradeoff between the accuracy and computation time of these methods in performing the analysis is an important issue that is rarely investigated in the previous research. This paper accordingly proposes a new method for EEG signal analysis through Self-Organizing Map (SOM) clustering and Deep Belief Network (DBN) approaches to efficiently improve the computation and accuracy of the previous methods. The method is developed using SOM clustering …

IntroductionNitrate supplementation in the form of beetroot juice (BRJ) ingestion has been shown to improve exercise tolerance during acute hypoxia, but its effect on exercise physiology remains unstudied during sustained terrestrial high altitude exposure. We hypothesized that performing exercise at high altitude would lower circulating nitrate and nitrite levels and that BRJ ingestion would reverse this phenomenon while concomitantly improving key determinants of aerobic exercise performance.MethodsTwenty seven healthy volunteers (21 male) underwent a series of exercise tests at sea level (SL, London, 75 m) and again after 5–8 days at high altitude (HA, Capanna Regina Margherita or “Margherita Hut,” 4,559 …

In group-living vertebrates, dominance status often covaries with physiological measurements (e.g. glucocorticoid levels), but it is unclear how dominance is linked to dynamic changes in physiological state over a shorter, behavioural timescale. In this observational study, we recorded spontaneous aggression among captive juvenile pheasants ( Phasianus colchicus ) alongside infrared thermographic measurements of their external temperature, a non-invasive technique previously used to examine stress responses in non-social contexts, where peripheral blood is redirected towards the body core. We found low but highly significant repeatability in maximum head temperature, suggesting individually consistent thermal profiles, and some indication of lower head temperatures …

Abstract. The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project aims to characterise the structure and orogenic processes involved in a major collisional mountain belt by multidisciplinary geoscientific research. Located in western central Sweden, the project has drilled two fully cored deep boreholes into the bedrock of the deeply eroded Early Paleozoic Caledonide Orogen. COSC-1 (2014) drilled a subduction-related allochthon and the associated thrust zone. COSC-2 (2020, this paper) extends this section deeper through the underlying nappes (Lower Allochthon), the main Caledonian décollement, and the upper kilometre of basement rocks. COSC-2 targets include the characterisation of orogen-scale detachments, …

The polar bear (Ursus maritimus) is a popular and easily recognisable species and has a long history of being housed in zoological collections. However, due to concerns regarding space requirements and welfare, many zoos have since removed this species from their collection plans. Polar bears require spacious enclosures with considerable amounts of enrichment and are susceptible to stereotypy if their needs are not met. Yorkshire Wildlife Park, UK, has set up a large enclosure to demonstrate best-practice care of polar bears. Observations of four male captive polar bears were conducted at the collection, to investigate behaviour and sociality between the …

AbstractThe Black Death (1347–1352 ce) is the most renowned pandemic in human history, believed by many to have killed half of Europe’s population. However, despite advances in ancient DNA research that conclusively identified the pandemic’s causative agent (bacterium Yersinia pestis), our knowledge of the Black Death remains limited, based primarily on qualitative remarks in medieval written sources available for some areas of Western Europe. Here, we remedy this situation by applying a pioneering new approach, ‘big data palaeoecology’, which, starting from palynological data, evaluates the scale of the Black Death’s mortality on a regional scale across Europe. We collected pollen …

Human–animal interaction (HAI) can be valuable for captive animals, and many zoo-housed species benefit from interactions with their keepers. There is also an increasing body of evidence that some animal species possess personalities that are temporally consistent. However, the majority of zoo research, particularly on personality and HAI, traditionally has focused on mammals, and there are comparatively fewer studies on reptiles. Research was undertaken at the Faunistic Park Le Cornelle, Italy, to investigate the effects of approach tests and food interaction events on 5 male and 5 female Aldabra tortoise (Aldrabrachelys gigantea) behavior. During human–tortoise interactions, continuous focal sampling of …

As the COVID-19 pandemic moves into its third year, there remains a need for additional animal models better recapitulating severe COVID to study SARS-CoV-2 pathogenesis and develop countermeasures, especially treatment options. Pigs are known intermediate hosts for many viruses with zoonotic potential and are susceptible to infection with alpha, beta and delta genera of coronaviruses. Herein, we infected young (3 weeks of age) pigs with SARS-CoV-2 using a combination of respiratory and parenteral inoculation routes. Pigs did not develop clinical disease, nor macroscopic or microscopic pathologic lesions upon SARS-CoV-2 infection. Despite occasional low levels of SARS-CoV-2 genomic RNA in the …
