Extending the Nutritional Geometric Framework to Three Dimensions
(University of ExeterCollege of Life and Environmental Sciences, 2015-08-25)Nutrition has pervasive effects on an organism’s fitness, influencing traits across life history stages from early development and reproduction to ageing and lifespan. Consequently an understanding of these effects, and ... -
Direct effects of increasing temperatures on birds
(University of ExeterCollege of Life and Environmental Sciences, 2018-02-28)Increasing air and sea temperatures are driving global ecological change. Here, I explore the direct effects of increasing temperatures on birds, which has thus far been studied less than the indirect effects. In Chapter ... -
The Public Health Impacts of Pollen on Allergic Rhinitis and Asthma
(University of ExeterMedical School, 2017-09-18)Pollen grains produced by grasses, weeds, and trees are some of the most common stimuli associated with exacerbations of allergic rhinitis and asthma. The pollen seasons can be associated with significant health impacts ... -
Oxidative shielding and the cost of reproduction in the blue tit Cyanistes caeruleus
(University of ExeterCollege of life and environmental sciences, 2017-10-20)The cost of reproduction is considered to be a cornerstone of life history theory. However, the physiological mechanism that underpins the cost of reproductionremains unclear. Recently, considerable interest has been ... -
Optimisation of Low-Cost Lignocellulose Reprocessing for Industrial Ethanol Production
(University of ExeterCollege of Life and Environmental Sciences, 2018-04-24)The expanding global demand for transportation fuels and stringent governmental pollution policies have prompted energy supplier investment in the development of renewable energy technologies. Bioethanol is a renewable, ... -
Camouflage and Pattern Change in the Common Shore Crab Carcinus maenas
(University of ExeterBiosciences, 2017-09-19)In nature, one of the most common and effective adaptions for reducing the threat of predation is to decrease the likelihood of detection through camouflage. The shore crab (Carcinus maenas) faces several predators in the ... -
Engineering Complex Carbohydrate Catabolism in Industrial Bacteria
(University of ExeterCollege of Life and Environmental Sciences, 2017-09-19)Second generation biofuels from the fermentation of lignocellulose have the potential to combat increasing problems between transport fuel use and the environment. However, current lignocellulosic degradation methods are ... -
Are Story Maps a useful flood hazard and risk communication tool: A case study from St Blazey.
(University of ExeterCentre for Geography, Environment and Society, 2017-11-09)Within the UK, flooding is a major concern and can cause significant impacts for communities. Attempts are being made to reduce the impacts of UK flooding and flood hazard and risk communication is an essential part of ... -
Prediction of the Performance of Regrind / Flotation Circuits using Laboratory tests and Quantitative Mineralogical Information
(University of ExeterCamborne School of Mines, 2017-10-13)Three different regrind circuits were studied to assess whether it possible to predict the performance of the regrind circuits and the subsequent enrichment process. Process audits were conducted on one iron ore regrind ... -
The Dreyfus-McDowell Debate and the Limits of Reason
(University of ExeterDepartment of Sociology, Philosophy and Anthropology, 2018-01-15)In the Dreyfus-McDowell debate, John McDowell makes the claim that what makes us distinctively human is our all-pervasive conceptual rationality. Hubert Dreyfus, on the other hand, argues that we are, at our best, absorbed ... -
Identifying novel interaction partners of the exocyst member Sec8 in the fission yeast Schizosaccharomyces pombe
(University of ExeterBiosciences, 2017-09-22)The exocyst is a complex of proteins classically known for its role in tethering secretory vesicles during exocytosis, but it has since been shown to participate in a whole host of other cellular processes. Several human ... -
Foraging behaviour and niche differentiation in two South Asian bee species
(University of ExeterPsychology, 2017-09-18)Pollination across the tropics, including in South Asia, is dominated by social bees. I investigated the behaviour of two species: Apis cerana (Eastern honeybee) and Tetragonula iridipennis (Indian stingless bee) which ... -
Enhanced content bio-imaging tools: realising the potential for high-throughput zebrafish bioassays
(University of ExeterCollege of Life and Environmental Sciences, 2017-05-19)Abstract Estrogenic endocrine disrupting chemicals (EEDCs) are environmental contaminants that can alter hormone signalling in both humans and wildlife, exerting their action through estrogen receptors (ERs). A wealth ... -
Uptake and Biological Impacts of Miroplastics and Nanoplastics in Sea Squirts
(University of ExeterCollege of Life and environmental Sciences, 2017-09-19)Microplastics have been detected in all marine regions and habitats, from the poles to the deep seas. A number of marine species are known to ingest microplastics, resulting in detrimental impacts. Preliminary work carried ... -
The role of Raman Spectroscopy in the detection of dysplasia in Barrett’s oesophagus
(University of ExeterCollege of Engineering, Mathematics and Physical Sciences, 2017-09-19)Introduction The incidence of oesophageal adenocarcinoma is increasing. Although improvements have been seen, the overall 5 year survival rate remains poor, at 15.1%. As with other cancers, the survival rate is highest ... -
Costs and benefits of diversity-generating immune mechanisms
(University of ExeterCollege of Life and Environmental Sciences, 2017-09-26)Organisms across the tree of life have evolved diversity-generating immune mechanisms (DGMs) to counteract selective pressures imposed by their parasites. Increased host diversity has a major impact on parasite epidemics ... -
The Effect of Dietary Nitrate Supplementation on Agility, Linear Sprint and Vertical Jump Performance
(University of ExeterSport and Health Sciences, 2017-09-15)Dietary nitrate (NO3-) supplementation has been shown to speed reaction time and enhance linear sprint speed and power production in an unfatigued state. It may therefore be suggested that NO3- supplementation could be ... -
The Interrogation of a Proposed Multikinase-Network in Burkholderia pseudomallei
(University of ExeterDepartment of Biosciences, 2017-09-25)Burkholderia pseudomallei is the causative agent of melioidosis, a disease associated with very poor clinical outcomes, including an up to 40% fatality rate and a significant relapse rate. The pathogen has a wide endemic ... -
