Investigating Endocrine‐Disrupting Properties Of Chemicals In Fish And Amphibians: Opportunities To Apply The 3rs, N Burden, Mr Embry, Th Hutchinson, Sg Lynn, Sk Maynard, Ca Mitchell, F Pellizzato, F Sewell, Kl Thorpe, L Weltje, Jr Wheeler

School of Geography, Earth and Environmental Sciences

Many regulations are beginning to explicitly require investigation of a chemical's endocrine-disrupting properties as a part of the safety assessment process for substances already on or about to be placed on the market. Different jurisdictions are applying distinct approaches. However, all share a common theme requiring testing for endocrine activity and adverse effects, typically involving in vitro and in vivo assays on selected endocrine pathways. For ecotoxicological evaluation, in vivo assays can be performed across various animal species, including mammals, amphibians, and fish. Results indicating activity (i.e., that a test substance may interact with the endocrine system) from in vivo …

Predicting Sea Pen (Pennatulacea) Distribution On The Uk Continental Shelf: Evidence Of Range Modification By Benthic Trawling, Anna Leena Downie, Tamsyn Noble-James, Ana Chaverra, Kerry L. Howell

School of Biological and Marine Sciences

Sea pen communities are United Nations General Assembly-designated Vulnerable Marine Ecosystems which occur worldwide in soft-bottom sediments where trawling often occurs. However, the ability of marine managers to assess, monitor and mitigate impacts to sea pens at national scales has been constrained by a limited understanding of their environmental requirements, geographical distribution and responses to trawling. In this study, we used random forest species distribution modelling (SDM) to predict the distribution of suitable habitat for 3 sea pen species (tall sea pen Funiculina quadrangularis, slender sea pen Virgularia mirabilis and phosphorescent sea pen Pennatula phosphorea) on the UK continental shelf, …

School of Geography, Earth and Environmental Sciences

Abstract. We report the distributions and stoichiometry of dissolved zinc (dZn) and cobalt (dCo) in sub-tropical and sub-Antarctic waters of the south-eastern Atlantic Ocean during austral spring 2010 and summer 2011/2012. In sub-tropical surface waters, mixed-layer dZn and dCo concentrations during early spring were 1.60 ± 2.58 nM and 30 ± 11 pM, respectively, compared with summer values of 0.14 ± 0.08 nM and 24 ± 6 pM. The elevated spring dZn concentrations resulted from an apparent offshore transport of elevated dZn at depths between 20–55 m, derived from the Agulhas Bank. In contrast, open-ocean sub-Antarctic surface waters displayed largely …

The silver-cheeked toadfish (Lagocephalus sceleratus, from the pufferfish family Tetraodontidae) and the Pacific red lionfish (Pterois miles, family Scorpaenidae) have recently invaded the Mediterranean Sea. Lagocephalus sceleratus has spread throughout this entire sea with the highest concentrations in the eastern basin, while more recently, Pterois miles has spread from the Eastern to the Central Mediterranean Sea. Their effects on local biodiversity and fisheries are cause for management concern. Here, a comprehensive review of predators of these two species from their native Indo-Pacific and invaded Mediterranean and Western Atlantic ranges is presented. Predators of Tetraodontidae in general were reviewed for their …

A Hitchhiker Guide To Manta Rays: Patterns Of Association Between Mobula Alfredi, M. Birostris, Their Symbionts, And Other Fishes In The Maldives, Aimee E. Nicholson-Jack, Joanna L. Harris, Kirsty Ballard, Katy M.E. Turner, Guy M.W. Stevens Jul 2021

A Hitchhiker Guide To Manta Rays: Patterns Of Association Between Mobula Alfredi, M. Birostris, Their Symbionts, And Other Fishes In The Maldives, Aimee E. Nicholson-Jack, Joanna L. Harris, Kirsty Ballard, Katy M.E. Turner, Guy M.W. Stevens

School of Biological and Marine Sciences

Despite being among the largest and most charismatic species in the marine environment, considerable gaps remain in our understanding of the behavioural ecology of manta rays (Mobula alfredi, M. birostris). Manta rays are often sighted in association with an array of smaller hitchhiker fish species, which utilise their hosts as a sanctuary for shelter, protection, and the sustenance they provide. Species interactions, rather than the species at the individual level, determine the ecological processes that drive community dynamics, support biodiversity and ecosystem health. Thus, understanding the associations within marine communities is critical to implementing effective conservation and management. However, the …

School of Nursing and Midwifery

Phase angle (PhA) is a body composition parameter that measures changes in the amount and quality of soft tissue. Few studies have explored PhA in pregnancy or postpartum. The aim of this study was to explore the PhA during the first year postpartum in a Belgian cohort using data from the control group of the INTER-ACT study, an intervention trial targeting those with excess gestational weight gain. A secondary aim was to examine associations between PhA and potential explanatory variables. Women aged ≥18 with excessive weight gain in a singleton pregnancy and without a chronic disease were eligible. Data collection …

Usability Of Sentinel-3 Satellite Ocean Colour Data For Examination And Chlorophyll Gradient Classification Of Submesoscale Island Wake Formations, Emmanuelle Simone Farrington Jul 2021

Usability Of Sentinel-3 Satellite Ocean Colour Data For Examination And Chlorophyll Gradient Classification Of Submesoscale Island Wake Formations, Emmanuelle Simone Farrington

The Plymouth Student Scientist

Submesoscale turbulent formations present challenges to sampling efforts due to their scale and transient nature. The development of successful sampling methods is imperative to achieving an understanding of the biological and ecological implications of these turbulent formations. This study assesses the viability of using Sentinel-3 OLCI multispectral satellite data for the study of submesoscale island wake formations. This research subsequently samples the eddies and filaments with virtual transects of satellite chlorophyll products, calculates metrics such as formation gradient and FWHM, identifies key environmental drivers of wake characteristics, and presents a novel framework by which to classify these formations. The study …

Habitat Modelling Of The Harbour Porpoise (Phocoena Phocoena) In Southwest Uk: Effects Of Depth, Slope And Tidal State, Jade L. Buttifant

The Plymouth Student Scientist

The harbour porpoise, Phocoena phocoena, is a widespread cetacean species in the Northeast Atlantic, with a year-round distribution around the UK. The south-west experiences the highest bycatch rates in the UK and is the main threat to P. phocoena populations. Yet here there is limited information on their abundance, distribution, and habitat preferences. This study aims to understand harbour porpoise species-habitat relationship in the UK south-west, which may be used to inform conservation management and sustain valuable populations. From boat-based visual surveys conducted over summers 2017-2019 from Plymouth to St Marys in the Scilly Isles, habitat modelling using generalised additive …


Working Memory Modules On The Threshold To Consciousness, Antonio Martin Jul 2021

Working Memory Modules On The Threshold To Consciousness, Antonio Martin

The Plymouth Student Scientist

Current literature is claiming for an important relationship between conscious experiencing and executive functions (mainly working memory). Since there is still a lack of empirical evidence relating those mental processes, the aim of this research is to continue exploring those relations by finding out how different components of working memory may affect the threshold to consciousness. The experiment contained three groups of people who performed two concurrent computerized tasks. The first one consisted of a replication of a priming and subjective visibility task (de Loof et al., 2013) for all the groups. Both experimental groups differed from the control group …

The Relationship Between Sociodemographic Factors And The Snacking And Drinking Behaviours Of Children Aged Between 1 And 5 Years In Early Years Settings Across Plymouth, Ashleigh Hellier

The Plymouth Student Scientist

Sugar consumption amongst children continues to sit above the current UK recommendations, contributing to rates of obesity and dental caries in this group. Previous research has focused on children of school age, investigating the role of parental income and education on child diet quality. The aim of this research was to assess the relationship between sociodemographic factors and the consumption of snacks and drinks by children between 1 and 5 years attending childcare settings across Plymouth. A questionnaire was distributed to settings to be filled out by parents/carers, measuring occupation, living situation and the number of children in the family, …


The Use Of Novel Lung Alveolar Macrophage Model, Max Planck Institute Cells, To Demonstrate The Differential Effects Of Smooth And Rough Mycobacterium Abscessus Forms On Il-6 And Il-1b Induction, Thanthri Peiris Jul 2021

The Use Of Novel Lung Alveolar Macrophage Model, Max Planck Institute Cells, To Demonstrate The Differential Effects Of Smooth And Rough Mycobacterium Abscessus Forms On Il-6 And Il-1b Induction, Thanthri Peiris

The Plymouth Student Scientist

Mycobacterium abscessus frequently initiates respiratory infections in humans and is of clinical concern in patients with cystic fibrosis who develop secondary pulmonary infections. Alveolar macrophages and innate responses play a crucial role in the pathogenesis of M. abscessus. The virulence potential of M. abscessus was suggestive of cell surface transition of glycopeptidolipid loss from the smooth biofilm producing strain to transform into the rough invasive variant. This study focuses on innate responses of three strains of M. abscessus; NCTC rough morphotype, CL-B (DC088-B) smooth morphotype and CL-C (DC088-C) mixed morphotype; each isolated and used as heat and formalin killed stimulants. …


Acute Stress, Friend Or Foe: An Investigation Of Free Recall Ability For Incongruent Items When Placed Under Acute Psychological Stress, Anna Adkins Jul 2021

Acute Stress, Friend Or Foe: An Investigation Of Free Recall Ability For Incongruent Items When Placed Under Acute Psychological Stress, Anna Adkins

The Plymouth Student Scientist

Experiencing stress during a working week is typical for most of the population, but the effects of acute stress on individuals is less clear cut, particularly in relation to memory ability. Research suggests that acute psychological stress can enhance memory ability, due to increased neuroplasticity following stress and stress hormones diverting attention to information congruent to the stressful environment. The current research investigated the effects of stress on free recall ability when the stimuli are incongruent to the stressor. Forty-four Psychology undergraduates were exposed to both a stress condition (Modified Trier Social Stress Test- free speech on Social Psychology) and …


The Effect Of Chlorhexidine Mouthwash Vs Propolis Mouthwash On The Nitrate-Reducing Activity Of Oral Bacteria And Vascular Control In Healthy Individuals, Stephanie Ellis Jul 2021

The Effect Of Chlorhexidine Mouthwash Vs Propolis Mouthwash On The Nitrate-Reducing Activity Of Oral Bacteria And Vascular Control In Healthy Individuals, Stephanie Ellis

The Plymouth Student Scientist

Nitrate and nitrite molecules are involved in the synthesis of nitric oxide (NO), a gaseous vasodilatory molecule, via the nitrate-nitrite-NO pathway. Oral bacteria are responsible for the reduction of nitrate to nitrite making them important regulators in NO production and vascular control. This paper aimed to investigate whether a laboratory-made propolis mouthwash maintained the oral nitrate reducing capacity (ONRC) of commensal bacteria compared with a chlorhexidine (CHX) mouthwash and the effects of this on vascular function in healthy individuals. Twenty-eight healthy participants visited the laboratory on two occasions where anthropometric, ONRC, blood pressure and vascular function data were collected. Between …

High-Resolution Stochastic Downscaling Method For Ocean Forecasting Models And Its Application To The Red Sea Dynamics, Georgy I. Shapiro, Jose M. Gonzalez-Ondina, Vladimir N. Belokopytov Jul 2021

High-Resolution Stochastic Downscaling Method For Ocean Forecasting Models And Its Application To The Red Sea Dynamics, Georgy I. Shapiro, Jose M. Gonzalez-Ondina, Vladimir N. Belokopytov

School of Biological and Marine Sciences

Abstract. High-resolution modelling of a large ocean domain requires significant computational resources. The main purpose of this study is to develop an efficient tool for downscaling the lower-resolution data such as those available from Copernicus Marine Environment Monitoring Service (CMEMS). Common methods of downscaling CMEMS ocean models utilise their lower-resolution output as boundary conditions for local, higher-resolution hydrodynamic ocean models. Such methods reveal greater details of spatial distribution of ocean variables; however, they increase the cost of computations and often reduce the model skill due to the so called “double penalty” effect. This effect is a common problem for many …


Differentiation Of South African Coastal Rock Pool Ochthebius Is Associated With Major Ocean Currents (Coleoptera: Hydraenidae), David T. Bilton Jul 2021

Differentiation Of South African Coastal Rock Pool Ochthebius Is Associated With Major Ocean Currents (Coleoptera: Hydraenidae), David T. Bilton

School of Biological and Marine Sciences

A number of non-marine coastal invertebrate species have been found to constitute (semi-) cryptic species complexes in recent years. Here it is revealed that rather than a single widespread species, distributed from the Namibian border to the Cape south coast, South African coastal rock pool Ochthebius Leach, 1815 previously referred to Ochthebius capicola (Péringuey, 1892) comprise two distinct taxa. Ochthebius capicola (s. str.) is apparently restricted to the Benguela Ecoregion on the west coast, being replaced by Ochthebius mlamboi sp. nov., in south and east coast localities influenced by the Agulhas Current, including areas of the Eastern Cape province well …

School of Engineering, Computing and Mathematics

Surface modification with linker molecules is necessary for the effective immobilization of bioreceptors and for improving the performance of biosensors. In this work, we present a novel functionalization technique to attach amine (NH2) linker on graphene-based sensor surfaces. This is achieved by reacting the commercially available reduced graphene oxide (rGO) screen-printed electrodes (SPEs) with ammonia solution at room temperature. The NH2 linkers are attached predominantly on the edge and defect sites of rGO SPE through chemisorption as shown by XPS, Raman and FTIR analysis. The functionalized SPEs are further characterized using morphological and electrochemical techniques. The validation of the linker …

Healthy Herds In The Phytoplankton: The Benefit Of Selective Parasitism, Davis Laundon, Thomas Mock, Glen Wheeler, Michael Cunliffe Jul 2021

Healthy Herds In The Phytoplankton: The Benefit Of Selective Parasitism, Davis Laundon, Thomas Mock, Glen Wheeler, Michael Cunliffe

School of Biological and Marine Sciences

The impact of selective predation of weaker individuals on the general health of prey populations is well-established in animal ecology. Analogous processes have not been considered at microbial scales despite the ubiquity of microbe-microbe interactions, such as parasitism. Here we present insights into the biotic interactions between a widespread marine thraustochytrid and a diatom from the ecologically important genus Chaetoceros. Physiological experiments show the thraustochytrid targets senescent diatom cells in a similar way to selective animal predation on weaker prey individuals. This physiology-selective targeting of ‘unhealthy’ cells appears to improve the overall health (i.e., increased photosynthetic quantum yield) of the …
