Fluorescent Proteins And Chromoproteins In Phylum: Cnidaria, Mario Lewis

The Plymouth Student Scientist

Green fluorescent protein was first discovered in Aequorea victoria. Its significance in a continually expanding range of scientific applications led to the discovery of an abundance of homologous fluorescent proteins and non-fluorescent chromoproteins in a variety of species in the phylum Cnidaria. The document reviews the various proposed hypotheses on the biological functions and biochemistry of fluorescent proteins and chromoproteins, wherein a full resolution remains elusive and is the subject of on-going debate. Mutagenesis has provided novel variants and insights into the relationship between the spectral characteristics and chromophore structures of fluorescent proteins that encompass the visible spectrum. Fluorescent proteins …

Effects Of Algal Toxicity On The Clearance Rate Of The Blue Mussel (Mytilus Edulis), Samantha Bowgen

The Plymouth Student Scientist

The purpose of this study was to investigate the effect of toxic strains of Karlodinium veneficum on the clearance rate of Mytilus edulis. Suspensions of the toxic strain and the non-toxic strain of K. veneficum, mixed with an alternative non-toxic species, Prorocentrum micans, were made and performed as parallel experiments in order to compare their effects on clearance rate. Clearance rate was measured by taking samples from suspensions every five minutes up to 30 minutes, and counting the algal cells found within each sample using a Sedgewick rafter slide. No significant difference was found between the two experiments (F (9.322, …

Effects Of A Gardening Task On Chocolate Craving, Sarah-Jane Baugh

The Plymouth Student Scientist

Two concepts, craving and nature, were brought together to investigate the effects of a gardening task on chocolate craving. Participants (n = 105) completed a chocolate craving induction before taking part in one of three, five minute tasks (gardening, plasticine, counting). Measures of craving, mood, arousal, attention and heart rate were recorded. The gardening task was found to have beneficial effects with participants experiencing significant changes in energetic arousal (p= .01) and feeling good (p< .01); however, no significant effects were found in the other measures.

The Effect Of Itgd Sensitivity And Contact On Attitudes Towards Burqas, Sophie Augarde

The Plymouth Student Scientist

The presented research investigates whether intergroup disgust sensitivity (affect-laden construct reflecting individual differences to experience revulsion towards outgroups) predicts greater prejudicial attitudes towards burqas. In addition to investigating the effect of ITGD sensitivity on prejudicial attitudes, types of contact (no contact, imagined contact and physical contact) between participants and an outgroup member were investigated to assess the efficacy of reducing prejudice towards women who wear burqas. ITGD sensitivity along with attitude towards burqas was measured over two sessions. Results indicated that there was no statistically significant effect of ITGD sensitivity or contact type on attitudes towards burqas. However, mean score …

An Evaluation Of Whether Artificial Refuge Traps Or Baited Traps Are The Most Effective Method For Trapping White-Clawed Crayfish (Austropotamobius Pallipes), Kathryn Walter

The Plymouth Student Scientist

Britain’s only native crayfish species, the white-clawed crayfish Austropotamobius pallipes are threaten through rapid population declines caused by non-indigenous species, habitat degradation and pollution. This study focuses one of the last remaining small A. pallipes population in the Creedy Yeo River, Devon. This study aims to decipher whether the use of artificial refuge traps (ARTs) or baited traps are the most effective method of catching this species, to aid translocation efforts to conserve the remaining population under threat from the American signal crayfish Pacifastacus leniusculus. The capture rate of each type of trap was studied at four sites along the …

Location, Demographic, Lifestyle And Behavioural Influences On Household Participation In Bournemouth Borough Council's Kerbside Recycling Scheme, Stephanie Rooke

The Plymouth Student Scientist

Bournemouth Borough Council (BBC) is performing well in recycling and currently has a recycling rate of 63.9%, but there is still room for BBC to improve the efficiency of the existing ‘Big Bin’ dry kerbside recycling collection scheme and increase the recycling rate further. The aim of the study was to identify the socio-economic groups which participate the least, or contaminate the most, in BBC’s kerbside recycling scheme. A participation survey was carried out over three consecutive collection cycles for three recycling rounds ‘RW1, RW2 and RW5’ to measure how many times each individual household set out their recycling bin …

The Conservation Biology And Ecology Of The African Leopard Panthera Pardus Pardus, Ross Tyzack Pitman

The Plymouth Student Scientist

The African leopard Panthera pardus pardus is an apex predator, and a reliable indicator of a healthy ecosystem. Currently assessed as ‗near threatened‘ by the IUCN Red List of Threatened Species, leopards are exposed to a range of threats that include: habitat loss and/or degradation, depletion of natural prey, conflict with people, consumptive- and non-consumptive practices, and the illegal trade of leopard products. Leopards have disappeared from 37% of their historical range, and are continuing to decline. Leopards have been extirpated across many areas of Africa, especially where people are densely populated, which has left patchily distributed leopard populations throughout …

Spatial And Temporal Patterns Of Erosion Along The Holderness Coastline, North East Yorkshire, Uk, Verity Macfarlane

The Plymouth Student Scientist

There is an increasing problem of erosion in coastal environments, particularly in soft material cliffs which need to be protected; migration to these environments is increasing, up to 75% more of the total population is predicted to live in close proximity to the coast by 2020. The Holderness coast (located in North East Yorkshire, UK) is the fastest eroding coastline in Europe. It comprises of soft clay, glacial till deposits from the Devensian period (18-13Ka). Previous studies have calculated that many parameters such as till properties, cliff geomorphology, cliff topography, strength and reaction to varied water contents are varied throughout …

Biologging Science: Advances In Our Knowledge Of Seabirds And Their Behaviours, David Evans

The Plymouth Student Scientist

The use of miniature tags attached to free-living animals to record data is termed ‘biologging’. This procedure has been used to study seabirds since the 1970’s and our knowledge of their behaviour, physiology and migration has advanced through the decades, along with the potential for conservation of species. Technological advances in recent years have improved data resolution and storage, enabling a better understanding of seabirds and their environment

The Effects Of Logging And Fragmentation On Bird Diversity, Bethany Mccarthy

The Plymouth Student Scientist

Deforestation and forest degradation is occurring globally at an alarming rate. The annual net loss of forest cover has been reduced in the past decade through sustainable forest management and conservation measures. Despite this, the remaining forest is becoming increasingly degraded with the total area of primary forest declining. Avian diversity has been shown to decline in degraded and fragmented forests due to logging activities. In this review the impacts of logging on avian communities are assessed by comparing diversity between primary forest and degraded secondary forest, industrial plantations and forest fragment sizes. The major organisations and current initiatives that …

The Use Of Errorless Learning In The Rehabilitation Of Action Disorganisation Syndrome: A Case Study, Blaize Dymond

The Plymouth Student Scientist

This case study investigates the use of errorless learning in the rehabilitation of action disorganisation syndrome (ADS). Case DL suffered 2 traumatic brain injuries to the frontal lobes (2002 and 2010) and presents with a clear case of ADS. DL displays high levels of disorganisation when engaging in sequential tasks. Errorless learning was used in an attempt to rehabilitate abilities in two everyday routine sequential actions; making a cup of tea and making toast with butter and jam. Errorless learning involves the deliberate prevention of errors using both verbal and physical prompts. The intervention resulted in a significant decline in …

The Positive Effects Of Aquarium Visits On Children's Behaviour: A Behavioural Observation, Hazel Cocker

The Plymouth Student Scientist

To date research has found a positive effect of blue spaces on adults’ wellbeing. However, it remains to be seen whether these findings are also true for children. The present study aims to address this gap in the literature. The researchers observed children’s behaviour at the National Marine Aquarium across two weeks, including one where the Big Draw event was taking place. In line with restorative theories of natural environments (Kaplan, 1995, Ulrich, 1983), the current research found the exhibit had a calming effect on behaviour and increased levels of happiness across both weeks. During the Big Draw week children …

Mood Affective Outcomes From Alternate Learning Strategies: Cognitive Flexibility And Dyslexic Education, Dylan Williams

The Plymouth Student Scientist

It is theorized that persons with dyslexia and associated conditions may be vulnerable to negative wellbeing, alongside academic deficiency, which has been focused on more widely. This study aims to investigate this theory in teenagers, and to draw relationships with teaching methods. Participants were interviewed, and completed the PANAS (Positive and Negative Affect) scale for children, the Matson Evaluation of Social Skills for Youngsters, and the Educational Environment Survey (an assessment of perceptions on education and ability). Participants with dyslexia and associated conditions showed reduced wellbeing compared to controls, and identified distinct experiential differences of education. This study was successful …

Comparing Risk-Taking And Digit Ratio (2d:4d) In Offenders And Non-Offenders, Taja Anderson

The Plymouth Student Scientist

Offenders differ from non-offenders in their propensity to engage in risk-taking behaviour. The ratio of the index and ring fingers (2D:4D), a proxy of prenatal testosterone exposure, has been linked to risk-taking behaviour. The present study compared risk-taking in 45 male offenders and 66 non-offenders using the Balloon Analogue Risk Task (BART). Furthermore, it sought to determine the relationship between their 2D:4D ratios and risk-taking behaviours. No significant differences were found between the two groups in their risk-taking behaviour and no significant correlations were found between 2D:4D and risk-taking in either group. These findings are discussed in relation to previous …

How Will Ocean Acidification Affect Marine Photosynthetic Organisms? A Review, Michael Jarrold

The Plymouth Student Scientist

Atmospheric carbon dioxide is increasing year on year, mainly as a result of burning fossil fuels. Although carbon dioxide dissolves in the oceans, mitigating atmospheric effects, it does result in a reduction of the alkalinity of sea water; an effect termed Ocean Acidification (OA). The subsequent changes in carbon chemistry will most likely affect marine photosynthetic organisms in a number of ways; including the ability of organisms to build calcium carbonate shells or skeletons (calcification) and primary production. Previous work indicates that both processes respond to OA, but not always in the same way. Consequently the aim of this review …

Investigating Placebo Mechanisms: Could A Pdp System Exist?, Francesca Payne

The Plymouth Student Scientist

Placebo mechanisms are a neglected area of research. Kirsch’s (1985) response expectancy theory described the stimulus-placebo response process as direct and unmediated. However, Hyland (2011) argued that the placebo effect is mediated by a parallel distributed processing (PDP) system, whereby all cognitive input is processed simultaneously, resulting in perseveration of the placebo effect. The present study examined this theory by utilising a TENS device as a placebo ‘effecting’ reaction times to a computer task, with an additional cognitive load task to further test the PDP system’s existence. Although a general placebo effect was found that increased in the cognitive load …
