Project Description

Environmental management aims to achieve desirable ecosystem states and avoid adverse or degraded ones. This makes it vital to understand the effect of all different pressures that may be negatively affecting the ecosystem. Large ships (e.g. container vessels and tankers) frequently anchor in coastal areas for operational reasons, and some bays have a continuous presence of very large commercial vessels year-round. Such vessels can use very heavy anchors (10s of thousands of kg) which dig into the seabed, and very heavy chains, with diameters of over 1m and a weight of several 100s of kgs per m length are not unusual. At anchor, these ships move around on the wind and tide, and when the anchor is retrieved, the anchor and chain will disturb the seabed and impacting the fauna living in and on it. Although the effect of anchoring by yachts on seagrass beds and cruise ships on coral reefs has received some attention, we know virtually nothing about the effect of large commercial vessels on sedimentary seabed ecosystems. These impacts are of concern to organisations like Natural Resources Wales, Natural England and UK Harbour authorities that have to ensure that coastal seabed ecosystems are in a good state.

Aims and objectives

This aim of this PhD is to quantify the impact of anchoring on sedimentary seabed ecosystems on local and regional scales. This requires developing, remotely-sensed, measures of anchoring disturbance using Automatic Identification System data (AIS), and estimating the effect of anchoring disturbance on the biodiversity of the seabed ecosystem from survey data. After this relationship has been established, it can be combined with remotely-sensed maps of anchoring disturbance to make regional predictions of the impact of anchoring on the seabed. These assessments will feed into the assessment of seabed integrity that are needed for the UK Marine Strategy (UKMS) and the EU Marine Strategy Framework Directive. The PhD student will therefore integrate the disciplines of marine ecology, remote sensing, big data for applied marine management.

Project Structure

The student will develop methods to estimated anchoring disturbance of the seabed using AIS data. The effect of anchoring on fauna will be estimated using several existing datasets, and the student will also collect new data on boat-based surveys. This understanding will then be used to provide a regional scale assessment of the impact of anchoring on seabed integrity. The student will be trained in these techniques, and will undertake a placement at NRW, who provide evidence-based advice on ecosystem management.

The project will be supervised by Prof Jan Geert Hiddink at Bangor University, Dr Matthew Witt at Exeter University, Dr Adel Heenan at Global Fishing Watch and Mike Camplin at Natural Resources Wales.

Project Description

Nutrient pollution of the UK’s coasts is a growing environmental and economic issue – detrimentally affecting habitats, wildlife and livelihoods. This project will calculate the full potential of saltmarshes as Nature-based Solutions (NbS) harnessing theory biogeochemical processes to remove excess nitrogen from water, in both existing and newly created saltmarsh ecosystems. Additionally, this project will provide analysis of the policy and legislative opportunities, and barriers, for delivery of coastal restoration projects aiming to reduce nutrient pollution.

There is no doubt that this project will have real-world impact, leading to nutrient neutrality mitigation payment schemes enabling the restoration and creation of internationally important wildlife habitats: saltmarshes

Aims and Objectives

Although it is known that saltmarshes sequester nitrogen through sediment burial and remove it by denitrification, the full extent of these processes have not yet been fully studied. Our project will rectify this by 1) providing evidence grade data of current nitrogen removal rates of saltmarshes 2) calculating maximum removal rates and 3) analysing the potential newly created saltmarshes have for nitrogen removal. The latter will consist of looking at two different creation techniques: traditional management realignment and a novel “drag box” method using dredged material (Figure 1). Finally, a policy framework for the delivery of coastal restoration projects for nitrogen removal will be prepared.

Project structure

Not only will the successful candidate have access to a range of supporting facilities, equipment and technical advice (including use of, and training in wetland biogeochemistry, saltmarsh ecology, landscape management and habitat creation practises, and policy frameworks), they will be supervised by scientists at Bangor University, UKCEH and WWT with the combined expertise and experience to ensure project delivery. In addition, we will work closely with all of our Associate Partners throughout to ensure the project is informed by, and delivers, relevant evidence grade data and a policy framework suitable for use by policy makers and practitioners.

The project will be supervised by Christian Dunn at Bangor University, Angus Garbutt at the UK Centre for Ecology and Hydrology, Olly van Biervliet Principal Research Officer at Wildfowl and Wetlands Trust and Tom Godfrey at Land & Water.

Project Description

Coastal saltmarshes are central to environmental and social resilience, but are threatened by land conversion and climate change. Marshes are thought important to fisheries species, yet there is an absence of research from Europe, including fundamental knowledge on biodiversity, abundances and the governance systems that protect marshes for fish. Marshes are a priority habitat for restoration, but restoration is expensive and data is needed to demonstrate their ecosystem-service values, including for fisheries. You will sample saltmarsh fish across the UK to understand the importance of marshes and establish the causes for variation in biodiversity and abundances, including between natural and restored sites. You will couple environmental research to socio-environmental work, to establish which players and governance systems have a stake in marsh management. Your work will culminate with dynamic workshops, to identify the best ways to managing marshes for fisheries species. Join us to boost the environmental management of a critical coastal ecosystem.

This PhD will address critical questions to managing saltmarshes for fisheries species, using environmental and social science techniques. You will sample marshes to ask: Is there a north-south gradient in the importance of British marshes to fish and prawns, and what are the causes? Can restoration replicate the biodiversity and abundances seen at natural sites, and which marsh features boost habitat quality? How important are marshes to fish? Saltmarsh conservation targets will not be achieved without understanding the governance system. We expect marsh-fish relations to be under-represented in governance. Are we right? We believe the route to boosting marsh management for fisheries species is through identifying opportunities for future saltmarsh management. You will use workshops with marsh managers and stakeholders to identify that route to boosting marsh management.

You will receive environmental and social science training to strengthen your capacity for solving multidisciplinary challenges to environmental management. We will train you in saltmarsh field and laboratory approaches, taxonomy, and RNA/DNA analyses. You will gain skills in GIS mapping and digital elevation modelling to establish marsh landscape shapes. You will be taught sociological approaches, such as semi-structured interviews to surveying stakeholder insights and governance structures. You will learn how to distil your findings into governance recommendations for the stakeholder community. Training will include placement with the Wildfowl and Wetlands trust.

The project has four chapters: (a) Governance and stakeholder mapping, (b) UK-wide sampling of saltmarshes, (c) Lab-based assessment of marsh nursery importance and (c) Assessing barriers to managing marshes for fisheries species

Project Description

The project combines benthic ecology, functional ecology, social science and economics in the development of sustainable evidence-based tools for policy makers managing sustainable marine resources. This PhD seeks to answer whether functional trait-based approaches can yield ecologically sound indicators to assess benthic ecosystem function impacts from offshore wind installation and inform marine natural capital and services. The development of offshore renewable energy installations leads to an increasing number of man-made structures in the marine environment. Sensitivity of benthic communities to OWF impacts have been shown to be higher than previously thought, highlighting the need for increased understanding of changes in ecological functioning and cascade effects. The project is transdisciplinary, spanning natural science, social science and economics, and the candidate will ideally have experience or a strong interest in each of these disciplines.

The overarching approach will be to define and quantify the following benthic relationships:

OWF —> Functional Traits —> Ecosystem Process —> Ecosystem Services & Benefits and will address the following questions: Firstly, can applying trait analyses to existing OWF benthic community datasets reveal functional community changes between pre, post & operational construction phases. Secondly, can these changes be linked to changes in ecosystem process provision and lastly, can modelling of functional change inform ecosystem services and natural capital assessments. Linking these functions to ecosystem service delivery, and understanding how these linkages change under different biodiversity regimes and at different scales is of key importance. Developing an understanding of the mechanisms supporting these linkages is an underdeveloped but much needed area of research.

The student will be trained in benthic community data and trait-based approaches and analyses gaining analytical skills in R. The project will undertake several placements with collaborating organisations who provide evidence-based advice on ecosystem management, to focus thesis and research outputs.

The project is structured around several thesis outputs (3 data chapters, 1 review chapter and 1 synthesis chapter), culminating in several peer-reviewed articles.

The project will primarily be supervised by Dr Craig Robertson (Bangor University, lead supervisor), and Dr Stephen Watson (Plymouth Marine Laboratory, second supervisor) and Dr Philip Turner (The Crown Estate, co-supervisor), with support from Profs Jan Hiddink and Nicola Beaumont.

Project description

The scallop sector is one of the highest value commercial fisheries in the UK and supports a productive catch sector and processor businesses. Despite their economic relevance, the UK scallop fisheries lack robust management regimes to regulate effort and landings and minimize impacts on target and non-target species. The UK’s withdrawal from the EU represents an opportunity to prioritise and re-structure future UK fisheries management.

The proposed project will generate an evidence-base on the environmental, social and economic consequences of different harvest strategies and management measures for the UK scallop fishery.

The project is multidisciplinary and cuts across the disciplines of biology and ecology, sociology and economics. The candidate will have the opportunity to learn and develop numerical skills and engage with members of the scallop dredging industry to determine the drivers (social, environmental and economic) of fishers’ spatial behaviour and their preference of management measures for scallop stocks. During this project the candidate will benefit from working with fisheries science authorities (CEFAS, MSS) advising UK government on scallop fisheries management in the UK. Ultimately, the knowledge gained through this PhD will help inform future fisheries management decisions to improve the management of scallop stocks.

• Determine the drivers (social, environmental and economic) of fishers’ behaviour that influence fishers’ choices of where, when and why they fish where they do and determine their preference for management measures of scallop stocks

• Carry out environmental and economic evaluations of a range of management scenarios identified during earlier work in this PhD proje

• Make recommendations on management measures to improve the management of scallop fisheries currently being developed under Fisheries Management Plans (FMPs)

The project will be supervised by Dr Marija Sciberras from Heriot-Watt University, Dr Lynda Rodwell from the University of Plymouth and Dr Gwladys Lambert from CEFAS who bring expertise in ecological impacts of benthic fisheries, numerical and economic modelling. The candidate will receive further support from Dr Michael Bell and Dr Karen Alexander from Heriot-Watt University on biological and sociological aspects of the project.

Associate Partner: Historic England (https://historicengland.org.uk/research/current/discover-and-understand/coastal-and-marine/)

Project Description

Maritime cultural heritage is embedded in the practice of small-scale fishing: traditional ecological knowledge, maritime landscapes, historic landing places, traditional vessels, and all their associated skills and material culture. The fishing sector is going through transitions post-Brexit on top of environmental, generational and technological changes that are likely to further diminish the tangible and intangible heritage of fishing. How can we use this cultural legacy to drive greater sustainability within fisheries management before it is too late?

Aims and objectives

The research questions the project will address include:

• Investigation of the historical and cultural practices and knowledge that continue to exist and be associated with UK fishing communities, as well as practices that no longer take place, but which exist in memory, through associated activities, and embodied in historic artefacts, buildings and landscapes. Approaches will also explore why and how evidence of fishing practices have changed (or remained the same) over time.
• Assessment of the benefits that were or are gained from these practices at the individual and community levels, including economic, cultural, built environment and provisioning benefits.
• Exploration of the values and narratives associated with continuing traditions and/or heritage practices within fishing communities, and to what extent these differ across communities.

Training

This project is impact-oriented and is co-developed with Historic England as a CASE partner. To ensure that the work and outputs are in close alignment with Historic England’s (and other partner) needs, the student will work closely with Dr Antony Firth of Historic England as a co-supervisor on the project. The PhD candidate will initially train in cross-disciplinary approaches (exact training will depend upon their background and existing skill set), including conducting an internship (in person or online) with Historic England to understand the CASE partner’s perspectives, data needs, to generate fishing community contacts and identify existing archival or material sources known to Historic England. Training will also be undertaken as part of the CDT SuMMeR cohort, including access to relevant allied training via Heriot-Watt University (School of Social Science and Lyell Centre) and University of Exeter (Centre for Ecology & Conservation and ExeterMarine) research and doctoral training networks.

Project Structure

The initial stage of the project will refine the focus of the research, undertake literature review work and pilot case study fieldwork, as well as beginning to create a network of engagement partners. This will be followed by a period of fieldwork in a small number of case study locations. These will inform not only a final thesis submission but also practical / impact-focussed outputs of use for Historic England and partner organisations and stakeholders to support fishing heritage and historic environment connectivity and opportunities.

The project will be supervised by Dr Antony Firth (Head of Coastal & Marine Strategy, Historic England), Dr Ruth Thurstan (Senior Lecturer in Marine Social-Ecological Systems, University of Exeter) and Professor Ian Baxter (Professor of Historic Environment Management, Heriot-Watt University) (Lead Supervisor).

Associate Partner: Cornish Seaweed Company (https://www.cornishseaweed.co.uk/)

Project Description

Cultivation of microalgae and macroalgae (i.e. seaweeds) currently contributes about 20% of total global aquaculture biomass and is rising rapidly at 8% per year. Seaweed products are used by a range of industries including pharmaceuticals, cosmetics, agriculture and human food. Seaweed farming in the UK, as elsewhere, has increased in recent years, although still in its infancy. Two major limitations to continued expansion relate to a lack of information on the local impacts of cultivation, and an assessment of the socioeconomic and ecological benefits of seaweed farming.

This project will operate at the interface between fundamental ecology and applied research within a commercial environment, with significant input from non-academic partners. Specifically, the project will examine whether seaweed farms promote local biodiversity, attract and support commercially-important fisheries species, and contribute to local carbon uptake and sequestration. The work will also examine the social/economic benefits and challenges of seaweed farming and translate the findings to facilitate policy and decision making.

The overarching aim of the project is to quantify the ecological impact and changes to ecosystem services as a result of a seaweed farm. This overarching aim will be met by addressing the following, targeted questions:

1.     How does seaweed farming influence local biodiversity and habitat structure?

2.     Do seaweed farms provide favourable habitat for fisheries species?

3.     Does seaweed farming contribute to local carbon sequestration?

4.     What are the social and economic impacts (positive and negative) of a seaweed farm?

5.     What is the potential for seaweed farming to contribute to (and leverage from) contribution to UK economic, biodiversity and climate targets?

Q1-3 will require primary data collection at two farm sites in Cornwall (UK), using a range of approaches including benthic surveys, video/potting techniques and sediment coring. Q4-5 will involve synthesising data collected during the project along with existing evidence from the literature and information garnered from a range of stakeholders. Together, this will provide a robust evaluation of the stacked ecosystem service benefits of seaweed farming.

In addition to opportunities through the CDT, the successful candidate will receive training in taxonomy, sampling techniques, sediment biogeochemistry and statistical approaches. There will be opportunities to engage with industry and government agencies through the network of partners.

Following an initial period of training, information gathering and planning, targeted surveys will be conducted during seaweed growing seasons at two farm sites, over two years. Fieldwork will be interspersed with periods of sample processing and analysis, data exploration, and synthesis of existing information on socioeconomic impacts of seaweed farming. It is anticipated that the project will lead to several high quality scientific outputs as well as the development of tools to assist with decision-making, thereby having ‘real world’ impact.

Project Description

Background: This is an exciting opportunity to take part in a transdisciplinary PhD which will provide the post-holder with a wide range of skills to enable them to become an innovative, solution-driven researcher or practitioner, working at the science-policy interface. The project will cross the boundaries of natural, social and economic science to build on previous work and provide a holistic assessment of the provision of sandeel ecosystem services in Celtic Seas.

Sandeels (Ammodytidae) are a key genus of forage fish within the Celtic Seas, and the UK as a whole. They provide a vital trophic link between zooplankton and higher predators including several commercial fish species, seabirds, seals, and cetaceans. There is some evidence that predation on sandeels is linked to greater body condition in predatory fish. They provide multiple environmental and societal benefits, and understanding these will help communicate the potential impact of appropriate management and protection of their populations and habitat.

Aims and Objectives

The project will build on a previous North Sea Assessment, reducing model uncertainty and incorporating 1) fishing pressure, 2) climate change, 3) MPAs, and 4) plastic pollution into the natural capital assessment. The project will focus on four main objectives:

1) To review the ecosystem services provided by sandeels in the Celtic Seas;

2) To assess how those services will be impacted by future climate change/ plastic pollution scenarios.

3) To determine the contribution and nutritional importance of sandals to the diet of key commercial fish species;

4) To produce a natural capital account for sandeels in the Celtic Seas.

This work will provide a case study for the ICES Workshop on Assessing Capacity to Supply Ecosystem Services, ensuring dissemination at the science-policy interface.

Candidate requirements

The successful candidate would be expected to have basic laboratory skills, knowledge of marine biology/ ecology, and a passion for the sustainable management of marine resources.

Training

The post-holder will be primarily based at Plymouth Marine Laboratory where they will join a growing cohort of PhD students, and will learn valuable academic, policy and consultancy career skills (e.g. transferable writing and presentation skills, good laboratory practice, time management). They will be trained in ecosystem service assessments by Dr Samantha Garrard and Professor Nicola Beaumont (Plymouth Marine Laboratory), develop skills in fisheries research and DNA metabarcoding with Dr Benjamin Ciotti (University of Plymouth), and skills in natural capital accounting and ecosystem modelling with Jo Bayes and Jacob Bentley (Natural England). The post-holder will also benefit from attending training in the Ecopath with Ecosim food web modelling suite, provided by Natural England at the Department for Environment, Food and Rural Affairs (Defra) London office: Nobel House, and attending ICES working group meetings.

Project Description

Rapid expansion of offshore wind energy developments is necessary to tackle the climate crisis and to meet net zero targets. However, wind turbines may also have a negative impact on biodiversity, including species that are already struggling, such as seabirds. One favoured compensation option for balancing increased adult mortality is enhancing juvenile recruitment through the construction of artificial nesting structures. This studentship will characterise seabird nesting and foraging niches to inform the placement of offshore wind farms and artificial nesting structures and ensure long-term species protection under climate change. This multidisciplinary project will use animal tracking to characterise nesting and foraging habitat, as well as projection modelling to link current and future seabird nesting and foraging with the placement of offshore wind farms and artificial nesting structures. This project will improve methods used to understand the ecological consequences of offshore wind and mitigate impact.

The project aims to characterise the year-round ecological niche of kittiwakes throughout the North Atlantic; identify suitable areas for offshore wind farm licensing and construction of offshore and onshore artificial nesting structures to maximise species protection; and assess the impact of windfarms and artificial nesting structures on long-term species resilience under climate change.

The student will receive training in the analysis of animal movement data, ecological niche modelling, ocean and climate projection modelling, impact assessment analysis, and marine spatial planning approaches.

The project will be desk based, making use of existing datasets. It will suit a student keen to develop several different strands of analytical skillsets and expertise. The studentship will be based at the University of Exeter’s Cornwall Campus in Penryn and supervised by Dr Richard Sherley (University of Exeter), Prof. Simon Neill (Bangor University), Dr Catherine Horswill (Zoological Society of London), Sion Roberts (The Crown Estate), Dr Alice Trevail (University of Exeter), and Prof. Stuart Bearhop (University of Exeter)

Project Description

The blue economy is expected to double in value to USD 3 trillion by 2030, globally. Rapid expansion of diverse sectors (aquaculture, coastal tourism, shipping, mining and offshore renewables) can displace or dispossess ‘traditional’ maritime sectors of the ocean resources they depend upon. In particular, (small-scale) fisheries are “subtly and overtly squeezed for geographic, political and economic space” with important implications for governance processes (e.g., trust, participation and compliance) and outcomes (livelihoods, food security and sustainable management of resources). In the UK, there is strong growth predicted in offshore renewables and aquaculture sectors alongside expanding conservation and protection of marine space through, for example, Marine Conservation Zones and Highly Protected Marine Areas all of which is escalating tensions within fisheries and marine governance. This doctoral research responds to a desire by fisheries and marine managers and policy-makers in the UK to re-set relationships with fisheries stakeholders and, in turn, improve levels of engagement and collaboration in policy development and implementation, particularly as impetus on nature recovery and net zero strengthens.

Aims and objectives

The aim of this research is to understand fishers’ and industry experiences of and responses to ‘spatial squeeze’ and potential displacement within the UK’s blue economy, and to identify opportunities for trust-building and improved collaboration in fisheries and marine governance. The research is guided by four objectives, to:

1.   Create an evidence map of existing initiatives to document spatial squeeze of fisheries and its social, cultural, economic and ecological impacts in the UK.

2.   Collect primary data on the social impacts and everyday experiences of spatial squeeze, including its implications for trust in marine governance processes at multiple levels.

3.   Identify and analyse the governance processes and stakeholder strategies which mediate conflict and build trust.

4.   Co-create a road-map to re-build and strengthen trust and collaboration in fisheries and marine governance.

Training

In addition to core interdisciplinary training the post-graduate researcher will undertake advanced training in evidence synthesis and mapping and creative approaches such as transformative scenario planning (see work by Adam Kahane).

Project Structure

Year 1: Review academic literature and UK policy documents, refining research design, and begin systematic evidence mapping to identify how spatial squeeze is currently being documented and evaluated in the UK.

Year 2: Secondments with DEFRA and MMO to understand existing policy challenges. Mixed-methods research using surveys and interviews in two multi-level case studies (Marine Spatial Prioritisation and Fisheries Management Planning) to evaluate: the social impacts and everyday experiences of spatial squeeze; levels of trust among stakeholders, and; the strategies and processes that can mediate conflict and build trust.

Year 3 and 4: Experiment with future-looking participatory and creative approaches to co-create a road-map towards more trusting collaboration in UK fisheries and marine governance. Write up and submit PhD thesis. Develop a publication strategy.

The project will be supervised by Dr Louisa Evans (University of Exeter), Professor Mel Austen (University of Plymouth), Dr Edward Hind-Ozan (DEFRA), Dr Aisling Lannin (MMO).

Project Description

Elasmobranchs (sharks, skates and rays) are an iconic groups of species, however, overfishing and poor management has driven around 40% of NE Atlantic species to be threatened with extinction. MPAs represent an effective conservation strategy, however, to be successful, they must be designed to encompass critical elasmobranch habitats (e.g. hotspots, nursery-grounds). A key step towards this is advancing our understanding of critical elasmobranch habitats and underlying environmental drivers. This project will integrate novel, cutting-edge elasmobranch field survey techniques (drifting baited cameras) with social science (e.g. semi-structured interviews) to identify critical elasmobranch habitats and threat overlap.

Aims and objectives

Aim: Combine Local Fisheries Knowledge with data collected from novel survey methods to identify and understand critical elasmobranch habitats and threats.

Objectives:

O1. Summarise local knowledge from marine resource stakeholders about critical elasmobranch habitat-use and threat overlap within south-west UK.

O2. Test and optimise pelagic BRUVs in known pelagic shark hotspots.

O3. Use findings from O1 to identify and survey priority sites with BRUVs, acoustic telemetry and oceanographic instruments to determine elasmobranch relative abundance, distribution and underlying drivers.

O4. Combine information from O1-O3 to compare historic and present-day populations and review the risks, benefits, opportunities for monitoring, and mitigation strategies in the south-west.

O5. Conduct an industry solution focused field experiment to determine the effectiveness of e.g. a bycatch deterrent (identified through O4).

Training

The candidate will be trained in: semi-structured interviews, participatory mapping, BRUV (pelagic and benthic), ROV, acoustic telemetry and oceanographic surveys and will gain their personal home office tagging licence. The successful candidate will have access to state-of-the-art facilities and technical support at the University of Plymouth and will receive training in a variety of geostatistical models in the R statistical suite to model animal movement and abundance data with oceanographic variables. Crucially, the candidate will learn on placement with Natural England’s senior marine advisors about translating socio-ecological and oceanographic data into impactful management and policy.

Project Structure

The candidate will be based at the University of Plymouth within a lively marine research focused environment with direct access to research vessels, laboratories and field-survey equipment. The city is centrally placed in the south-west with easy access to a number of fishing ports across Dorset, Devon and Cornwall. The PhD data collection activities will be split between working at sea off fishing boats, and travelling to meet stakeholders around the south-west. The Natural England partner is based in Exeter which is only a short commute away where the student will be based for a 3 month placement during their PhD.

The project will be supervised by Dr Emma Sheehan, Associate Professor of Marine Ecology (University of Plymouth, lead supervisor), Dr Rachel Turner, Senior Lecturer in Environmental Social Science (University of Exeter), Dr Alec Moore, Fisheries Ecologist (Bangor University), Dr Ben Ciotti, Fisheries Ecologist (UoP), Dr Philip Hosegood, Associate Professor in Physical Oceanography (UoP), with Associate Partners Natural England.

Project Description

Increasing human use of the marine environment and competition for space from industries such as fishing, aquaculture, marine renewables, mining, oil and gas extraction and cable laying, have led to significant challenges of habitat loss and degradation. These challenges are compounded by the effects of climate change, including ocean acidification, warming, and deoxygenation, on marine species. The loss of species and habitats can lead to changes in, or loss of, ecosystem function and ultimately impact the services provided by the ecosystem. 

These ecosystem services are critical to supporting human health and well-being and thus should be, but are not yet, considered in marine environmental management fora. One of the challenges is that our understanding about the links between biodiversity and individual ecosystem services remains incomplete. Research in the terrestrial environment has found that the responses of biodiversity to drivers of change and the effects of biodiversity on ecosystem services may be explained by functional traits. Functional traits can determine an organism's response to pressures and their effects on ecosystem function and services. The aim of this studentship is to conduct research that draws together traits-based information, with habitat mapping approaches, and management scenario modelling, to inform development of natural capital approaches to non-coastal marine environmental management.

Aims and Objectives

In this project the student will conduct research to answer the following four questions:

1. What benthic marine organism traits are linked to ecosystem services and organism responses to human induced pressures?
2. Which benthic assemblages (biotopes) contribute most to functional diversity and ecosystem services, and what are their respective vulnerabilities to human induced pressures.
3. How is functional diversity, ecosystem services and species vulnerability spatially distributed throughout UK offshore waters?
4. How do UK offshore benthic ecosystems respond to management decisions and what are the societal implications in terms of risk to ecosystem services?

Training

This project brings together expertise in marine biology, habitat mapping and modelling, marine ecosystem management, and social sciences to investigate ways to implement natural capital-based approaches to managing offshore marine ecosystems. The student will receive training in systematic review, hierarchical modelling of species communities, GIS and R.

Project Structure

The student, while based at the University of Plymouth, will have the opportunity to spend time at Bangor University and undertake a 6 week placement with JNCC, gaining real world experience in marine environmental management. The project is structured around the four questions (intended as thesis data chapters), with different members of the supervisory team supporting different aspects of the PhD.

The project will be supervised by Kerry Howell (UoP, primary supervisor), supported by Craig Robertson (Bangor University), Sian Rees (UoP), Heidi Tillin (MBA) and Louise Anderson (JNCC).

Project Description

Transitional and coastal waters support a suite of ecosystem services that provide benefits and are increasingly being developed and exploited. Some efforts to restore ecosystems that provide services, such as seagrass, saltmarsh, and oyster reefs are having limited or variable success. Yet in other places, similar habitat creating species, such as intertidal seagrass, are thriving - seemingly without any intervention. The varying factor that links these successes and failures may be upstream water quality. Identifying opportunities to deploy nature-based solutions to tackle issues such as water quality and pollution regulation, net zero, net biodiversity gain and coastal resilience requires an understanding of connectivity between land and seascapes (the ‘wholescape’) in order to maximise the potential environmental and social benefits. You will work with a transdisciplinary team to develop the evidence for land-sea connectivity and the effects on coastal habitats and ecosystems. Outputs from this PhD will inform cross-business discussion at The Crown Estate (and elsewhere) on nutrient neutrality and opportunities that may exist to deliver nature-based solutions.

Aims and Objectives

You will make a significant contribution to an emerging global theme in science by developing a conceptual framework that enables wholescape systems thinking approaches to land and sea management. You will analyse empirical and model data on freshwater nutrients and flows to track catchment to coast nutrient loads and identify connections between land and sea. How variation in nutrient concentrations impact the quality and functions of coastal habitats is of increasing concern. You will evaluate the implications for potential nature-based solutions to help improve water quality and provide other ecosystem benefits. It is important that outputs from this PhD are action focused. You will work with The Crown Estate to test the conceptual framework and outputs from your research through a wholescape business assessment that will feed into ongoing discussions on emerging policies and markets.

Project Structure

The PhD will be largely desk based and has six chapters: (a) a literature review and development of the wholescape framework (b) analysis of water quality flows between land-sea (c) systematic review of links between nutrient loads, flows of ecosystem services, and nature-based solutions (d) assessment of ecological responses to elevated nutrient concentrations (e) business assessment (f) discussion.

The PhD will take both national and catchment based approaches. The latter will focus on data-rich case study sites such as the Solent and Tamar estuaries, the North Devon Biosphere Reserve, and Lyme Bay.

Training

You will receive training to strengthen your capacity for solving transdisciplinary challenges to environmental management. We will train you in coastal ecology, freshwater flows and quality, natural capital approaches, systematic reviews and business assessments.
