School of Biological and Marine Sciences
The effect of bedforms on frictional roughness felt by the overlying flow is crucial to the regional modelling of estuaries and coastal seas. Bedforms are also a key marker of palaeoenvironments. Experiments have shown that even modest biotic and abiotic cohesion in sand inhibits bedform formation, modifies bedform size, and slows bedform development, but this has rarely been tested in nature. The present study used a comprehensive dataset recorded over a complete spring–neap cycle on an intertidal flat to investigate bedform dynamics controlled by a wide range of wave and current conditions, including the effects of wave–current angle and bed …
Excitotoxic Lesions Of The Perirhinal Cortex Leave Intact Rats’ Gustatory Sensory Preconditioning, Jasper Robinson, Peter M. Jones, Emma J. Whitt
Excitotoxic Lesions Of The Perirhinal Cortex Leave Intact Rats’ Gustatory Sensory Preconditioning, Jasper Robinson, Peter M. Jones, Emma J. Whitt
School of Psychology
We report findings from two sensory preconditioning experiments in which rats consumed two flavoured solutions, each with two gustatory components (AX and BY), composed of sweet, bitter, salt, and acid elements. After this pre-exposure, rats were conditioned to X by pairing with lithium chloride. Standard sensory preconditioning was observed: Consumption of flavour A was less than that of B. We found that sensory preconditioning was maintained when X was added to A and B. Both experiments included one group of rats with lesions of the perirhinal cortex, which did not influence sensory preconditioning. We discuss our findings in the light …

School of Biological and Marine Sciences
Designated using a Statutory Instrument in 2008, Lyme Bay marine-protected area (MPA) is the UK's first and largest example of an ambitious, whole-site approach to management, to recover and protect reef biodiversity. The whole-site approach applies consistent management, in this case excluding bottom towed fishing, across the full 206 km2 extent of the MPA, thus protecting a mosaic of reef-associated habitats from regular damage, while still allowing less destructive fishing methods, such as static gear, rod and line, and diving.To assess the effectiveness of this management strategy for mobile taxa and the sustainability for those taxa that continue to be …

The continuing emergence of SARS-CoV-2 variants calls for regular assessment to identify differences in viral replication, shedding and associated disease. In this study, we compared African green monkeys infected intranasally with either the UK B.1.1.7 (Alpha) variant or its contemporary D614G progenitor. Both variants caused mild respiratory disease with no significant differences in clinical presentation. Significantly higher levels of viral RNA and infectious virus were found in upper and lower respiratory tract samples and tissues from B.1.1.7 infected animals. Interestingly, D614G infected animals showed significantly higher levels of viral RNA and infectious virus in rectal swabs and gastrointestinal tissues. Our …

Algae Sympoiesis In Performance: Rendering-With Nonhuman Ecologies, Sarah Blissett
School of Art, Design and Architecture
This article explores an ecodramaturgical approach to performance-making and research with algae. The first part considers the notion of ‘algae rendering’ as a methodological tool for theorising algae ecological relations which highlights links between representations of algae and their material effects. The second part considers how my embodied encounters with cyanobacteria algae, in the form of lichen, inspire new modes of working with algae in creative practice that explore how algae agencies ‘render’ bodies and environments. I also draw on an artistic case study by The Harrissons (1971) to illustrate principles of what I consider examples of ‘algae rendering’ in …

School of Nursing and Midwifery
Abstract Background: Globally, pressure is increasing on health and social care resources due to the aging population and growing prevalence of dementia. Companion robots, such as Paro, demonstrate strong potential for helping reduce this pressure through reported benefits including reduced agitation, depression, loneliness, care provider burden, and medication use. However, we previously identified that user-centered design of robot pets is both essential and understudied. We observed that commonly used robot pets are poorly matched to end-user requirements, and that end users and developers of robot pets differ significantly in their perception of appropriate design. This may explain some of the …

Background The pattern of change in maternal bone turnover throughout pregnancy is poorly characterized. Objectives We investigated changes across pregnancy in a marker of maternal bone resorption, urinary C-terminal telopeptide of type I collagen (CTX), the influence of gestational vitamin D supplementation, and associations between CTX and maternal postnatal bone indices. Methods MAVIDOS (the Maternal Vitamin D Osteoporosis Study) is a randomized, double-blind, placebo-controlled trial of 1000 IU cholecalciferol/d compared with placebo from 14 weeks of gestation to birth. Maternal second-void urinary α- and β-CTX were measured (ELISA) at 14 and 34 weeks of gestation; DXA was performed within 2 …

Stress-Testing And Credit Risk Revisited: A Shipping Sector Application, Anna Merika, Ioannis Negkakis, Henry Penikas
Stress-Testing And Credit Risk Revisited: A Shipping Sector Application, Anna Merika, Ioannis Negkakis, Henry Penikas
Plymouth Business School
Conventional stress-testing in credit risk management may considerably underestimate economic losses associated with the most negative scenarios. In this paper, we show that in order to properly stress-test credit risk, we need to derive initially the default correlation among assets or companies. Then a risk measure needs to be applied to the stressed default rate distribution, in order to obtain default rates attached to the most negative scenarios. We find that the application of both the stressed default correlation and the risk measure deliver considerable deviations from the conventional approach. To illustrate our approach we use 192 publicly listed shipping …

AbstractPhenotypic diversity in urinary metabolomes of different geographical populations has been recognized recently. In this study, urinary metabolic signatures from Western (United Kingdom) and South-East Asian (Thai) cholangiocarcinoma patients were characterized to understand spectral variability due to host carcinogenic processes and/or exogenous differences (nutritional, environmental and pharmaceutical). Urinary liquid chromatography mass spectroscopy (LC–MS) spectral profiles from Thai (healthy = 20 and cholangiocarcinoma = 14) and UK cohorts (healthy = 22 and cholangiocarcinoma = 10) were obtained and modelled using chemometric data analysis. Healthy metabolome disparities between the two distinct populations were primarily related to differences in dietary practices and body …

Rice blast is a devastating disease caused by the fungal pathogen Magnaporthe oryzae that threatens rice production around the world. The fungus produces a specialized infection cell, called the appressorium, that enables penetration through the plant cell wall in response to surface signals from the rice leaf. The underlying biology of plant infection, including the regulation of appressorium formation, is not completely understood. Here we report the identification of a network of temporally coregulated transcription factors that act downstream of the Pmk1 mitogen-activated protein kinase pathway to regulate gene expression during appressorium-mediated plant infection. We show that this tiered regulatory …
Synthesis Of Thresholds Of Ocean Acidification Impacts On Decapods, John I. Spicer, Nina Bednaršek
Synthesis Of Thresholds Of Ocean Acidification Impacts On Decapods, John I. Spicer, Nina Bednaršek
School of Biological and Marine Sciences
Assessing decapod sensitivity to regional-scale ocean acidification (OA) conditions is limited because of a fragmented understanding of the thresholds at which they exhibit biological response. To address this need, we undertook a three-step data synthesis: first, we compiled a dataset composed of 27,000 datapoints from 55 studies of decapod responses to OA. Second, we used statistical threshold analyses to identify OA thresholds using pH as a proxy for 13 response pathways from physiology to behavior, growth, development and survival. Third, we worked with the panel of experts to review these thresholds, considering the contributing datasets based on quality of the …

Benthic Assemblage Composition Of South Atlantic Seamounts, Amelia E.H. Bridges, David K.A. Barnes, James B. Bell, Rebecca E. Ross, Kerry L. Howell
School of Biological and Marine Sciences
Seamounts and oceanic islands rise from the seafloor and provide suitable habitat for a diverse range of biological assemblages including Vulnerable Marine Ecosystems (VMEs). Whilst they have been the focus of some work globally, there has been little description of the biological and physical environments of seamounts in the South Atlantic Ocean. In this study, we characterized benthic assemblage composition from 13 seamounts and oceanic islands spanning 8–40°S within the exclusive economic zones (EEZs) of Ascension Island, Saint Helena and Tristan da Cunha. Drop camera imagery was collected between 170 and 1000 m. All fauna present in images were identified …

Following peripheral nerve injury, transcription factors upregulated in the distal nerve play essential roles in Schwann cell reprogramming, fibroblast activation and immune cell function to create a permissive distal nerve environment for axonal regrowth. In this report, we first analysed four microarray data sets to identify transcription factors that have at least twofold upregulation in the mouse distal nerve stump at day 3 and day 7 post-injury. Next, we compared their relative mRNA levels through the analysis of an available bulk mRNA sequencing data set at day 5 post-injury. We then investigated the expression of identified TFs in analysed single-cell …

School of Biological and Marine Sciences
AbstractMegaphages, bacteriophages harbouring extremely large genomes, have recently been found to be ubiquitous, being described from a variety of microbiomes ranging from the animal gut to soil and freshwater systems. However, no complete marine megaphage has been identified to date. Here, using both short and long read sequencing, we assembled >900 high-quality draft viral genomes from water in the English Channel. One of these genomes included a novel megaphage, Mar_Mega_1 at >650 Kb, making it one of the largest phage genomes assembled to date. Utilising phylogenetic and network approaches, we found this phage represents a new family of megaphages. Genomic …

Land use conversion is generally accompanied by large changes in soil organic carbon (SOC). SOC influences soil erodibility through its broad control on aggregate stability, soil structure and infiltration capacity. However, soil erodibility is also influenced by soil properties, clay mineralogy and other human activities. This study aimed to evaluate soil organic carbon as proxy of soil erosion risk in the Nyumba ya Mungu (NYM) catchment in Northern Tanzania. Soil organic carbon (SOC) was measured by an AgroCares scanner from which the soil organic matter (SOM) was derived using the conversional van Bemmelen factor of 1.72. A regression analysis performed …

Whales contribute to marine ecosystem functioning, and they may play a role in mitigating climate change andsupporting the Antarctic krill (Euphausia superba) population, a keystone prey species that sustains the entireSouthern Ocean (SO) ecosystem. By analyzing a five-decade (1971–2017) data series of individual southern rightwhales (SRWs; Eubalaena australis) photo-identified at Península Valdés, Argentina, we found a marked increasein whale mortality rates following El Niño events. By modeling how the population responds to changes in thefrequency and intensity of El Niño events, we found that such events are likely to impede SRW population recoveryand could even cause population decline. Such outcomes …

Plasmid Fitness Costs Are Caused By Specific Genetic Conflicts Enabling Resolution By Compensatory Mutation, Jpj Hall, Rct Wright, E Harrison, Kj Muddiman, Aj Wood, S Paterson, Ma Brockhurst
School of Biomedical Sciences
Plasmids play an important role in bacterial genome evolution by transferring genes between lineages. Fitness costs associated with plasmid carriage are expected to be a barrier to gene exchange, but the causes of plasmid fitness costs are poorly understood. Single compensatory mutations are often sufficient to completely ameliorate plasmid fitness costs, suggesting that such costs are caused by specific genetic conflicts rather than generic properties of plasmids, such as their size, metabolic burden, or gene expression level. By combining the results of experimental evolution with genetics and transcriptomics, we show here that fitness costs of 2 divergent large plasmids in …

For many of us, when we think about glaciers, we might imagine cold, icy polar environments such as the Arctic or Antarctica and their associated characteristic fauna. However, the existence of glaciers is not limited to high latitudes, with numerous glaciers also found close to, or even within, the Tropics, where elevation is high enough for snow and ice to persist year-round. Indeed, high mountain regions at lower latitudes, such as the South American Andes and the Asian Himalayas, are home to many hundreds of glaciers and these glaciers provide important water resources for local populations. These mountain glaciers act …

Soil organic carbon (SOC) is widely recognised as pivotal in soil function, exerting im-portant controls on soil structure, moisture retention, nutrient cycling and biodiversity, which in turn underpins a range of provisioning, supporting and regulatory ecosystem services. SOC stocks in sub‐Saharan Africa (SSA) are threatened by changes in land practice and climatic factors, which destabilises the soil system and resilience to continued climate change. Here, we provide a review of the role of SOC in overall soil health and the challenges and opportunities associated with main-taining and building SOC stocks in SSA. As an exemplar national case, we focus on …
