PhD draft title: Analysis of phage that infect oak pathogens and the dynamics of phage population changes and bacterial community change in a disease lesion 
Info: There are currently no anti-microbial treatments available for AOD. However, bacteriophages (phages) are a biocontrol alternative to traditional antibiotic and copper compounds.  Phages, viruses that infect and kill bacteria, have been proven to be effective treatments for several bacterial tree pathogens. This study aims to isolate phages which infect the four AOD-associated bacteria species and characterise them via several assays to assess their suitability as biocontrol agents. It is also important to identify the extent and consequences of phage resistance; therefore, the coevolution dynamics of these different phages and bacteria species will be tracked over a period of 7 days, both in vitro and in planta. Seasonal sampling of infected trees will be performed to determine how phage diversity changes over symptom progression. Dependent on these findings, cocktails of the different phages will be trialled to assess their ability to reduce AOD symptoms and bacteria prevalence.

PhD draft title: Examining risk of new disease outbreaks in a diseased population using ash as a model
Info: Pseudomonas savastanoi pv. fraxinii causes canker disease in ash trees, and although it is widespread in the UK, the severity of the disease is relatively low. Why this is the case is not understood and there could be potential for severity to increase in trees weakened by other diseases like ash dieback or pest attack like Emerald Ash Borer. This project therefore aims to develop new tools to study this pathosystem and examine whether there is any potential threat of bacterial disease outbreaks in ash.

PhD Draft Title: Examining the impact of soil on tree health and disease progression.
Info: Soil around plant roots (rhizosphere) is critical to plant health and biotic and abiotic stresses in the tree rhizosphere may cause tree health to drop and make them more prone to disease. Previous work in the PuRpOsE project on protecting oak ecosystems has indicated that trees with acute oak decline may be pre-disposed to disease due to water fluctuations in the root system. This project aims to examine soil properties around diseased and healthy trees with a view to alleviating the stress. This project will work in concert with a PDRF to develop an experimental design to look at what changes occur in trees living in different soil environments. This should involve a study of tree changes (traits and internal metabolome and biochemistry) as well as monitor pathogen population changes and performance. Together, these experiments will allow us to understand how soil influences tree health and enable us to develop policy advice for this.

PhD Draft Title: Priming of defence in an elevated CO2  world
PhD: Priming of defence in an elevated CO2 world  - Rising CO2  levels are a reality of our current world, however the impact of this on plant species is still little understood. Elevated CO2 is believed to result in increased growth in some species however there are reports that elevated levels could negatively impact on plant defence making them more susceptible to pests & diseases. This project aims to understand how elevated CO2 will impact oak defence priming in both juvenile & mature oak trees against the oak pathogen powdery mildew & insect herbivores. This knowledge will allow humans to better assess risks to future forests & allow for better protection of these vital organisms.

PhD title:  A study of tree disease on St Helena
Info: Affiliated with St Helena Research Institute and CABI. St Helena is home to an abundance of endemic flora and fauna. The islands cloud forests are found at the volcanic peaks, providing a complex ecosystem for biodiversity to thrive. However, human activity has left much of the land barren of naturally occurring vegetation. This has fragmented communities of ecological importance and reduced genetic diversity. Due to this, as well as the introduction of invasive plants, many of the tree species on the island are threatened by diminishing numbers and increased risks of pests and diseases. One of the most fundamental species to this unique environment is the black cabbage tree (Melanodendron integrifolium) which is suffering from sudden death due to an unknown disease-causing agent. Other symptoms such as leaf wilt, yellowing, spotting and root rot are also seen across nurseries. Assessments of eDNA from samples taken from nurseries, wild black cabbage trees, as well as other species showing signs of disease, may indicate whether a pathogen is the most likely candidate for this dieback. These findings may then inform management decisions to help prevent the spread of disease, through methods such as plant clinics and media communication with locals, tourists and land owners

PhD title: Evaluating the threat of Xylella on UK trees 
Poster 2022 
Info: Xylella fastidiosa is a bacterium that is endemic to central America. It is an established pathogen in the US and is a recently emerging pathogen causing devastating disease in southern Europe. Presently, they are limited to Italy, Portugal, Spain and France, but detection of infected plants has been found in other countries in Europe triggering control and eradication procedures. Tree species like ash and oak have also been observed with Xylella infections in Europe, highlighting the wide host range of the pathogen. 

There is considerable concern around the potential threat to the UK’s horticulture and ecosystem, particularly to trees, should Xylella establish in the country and thus it is important that investment is made to fully understand the threat the pathogen poses. This will help with identifying the potential hosts for the pathogen and whether any resistance exists in the plant population. It will also help with identification and monitoring as well as considering the risk of widespread disease spread.

PhD: Forests are a terrestrial carbon sink, a home to biodiversity, provide clean air etc. Forest fires threaten these ecosystem services and also pose physical danger to households located on the vicinity. The high and increasing economic costs of forest fires can be reduced if we have a better understanding on the factors shaping the perceived risk of households. By using satellite and house price data our research will identify the size and persistence of the impact of pure information effect on the perception of forest fire risk.Forests are a terrestrial carbon sink, a home to biodiversity, provide clean air etc. Forest fires threaten these ecosystem services and also pose physical danger to households located on the vicinity.

PhD title: Effects of atmospheric Nitrogen pollution on Soil Carbon Storage and Greenhouse Gas Emission from Forests Soils
Info: Reactive forms of aerially derived nitrogen deposition sourced from agriculture are often scavenged by tree's and deposited within woodland systems. Understanding how enhanced rates of nitrogen deposition impact woodland soil with regard to soil organic carbon decomposition, microbial activity and the release of nitrous oxide and carbon dioxide is required to understand how our woodlands and their soils can be conserved and their provisions preserved.

Year of Study: Second 
PhD title: Life on the edge: New tools to track animal-forest trophic interaction across intact to degraded ecosystems
Info: Madagascar is a haven of floral and faunal endemism, with lemurs at the centre of engineering and maintaining the diverse and varied forest habitats the island comprises. There is no such thing as a healthy Malagasy forest without the endemic lemur communities. Forest degradation and loss of lemur communities form a destructive positive feedback loop, causing the loss of large fruiting trees and a shift in forest composition to smaller faster-growing trees less efficient at carbon sequestration. Forest health and function can be monitored through the tracking of changes in the diets of inhabitant lemurs, especially in edge habitats where they are forced to adapt to ongoing changes in resources as a result of degradation. This project aims to use biomarkers, tools used primarily in organic geochemistry for palaeoclimate reconstruction, to investigate the diets of lemurs from faeces, with the aim of developing these techniques to be applied to wild lemurs in the future to monitor forestry changes and forest-lemur interactions.

Xinshi Cheng
Prof. Jason Hilton (GEES) and Dr Andy Plackett (Bio)
Year of study: First
Further information: Xinshi is studying seed plant diversity and evolution from a systematic investigation of exceptionally well-preserved fossils seeds from the late Permian of China. The project will use seed morphology and anatomy and consider functional and ecological adaptations that will unravel how seed plants adapted to the environments and climates in which they lived. A key aspect of the project is to evaluate seed plant diversity through the Permian-Triassic Mass extinction approximately 252 million years ago in which some groups died out while others went on to dominate younger floras globally. Methodologies include analysis and reconstruction of fossil seeds from 3D X-ray computer tomography and synchrotron sources, comparative anatomy with fossil and living seed plants, and phylogenetic analysis.

Year of study: First 
Further information: Impact of CO2 rise on root, leaf and wood production: the future of tree C allocation. Previous research suggests that trees can carry out increased levels of photosynthesis under elevated CO2, but growth cannot increase indefinitely due to other limiting factors such as nutrient availability. This project will focus on a tree's ability to combat this by allocating extra carbon belowground by increasing root growth, exudation, and microbial activity to explore and obtain more nutrients and water. The research for this project will be carried out at BIFoR FACE, in collaboration with Forest Research and the Met Office. Root production will be measured through the collection of images using a minirhizotron camera, a non-destructive root investigation technique, which will then be vectored and converted to rates of root production. This methodology will be used alongside more traditional methods of root extraction and examination using soil cores. Data on root production will then be considered alongside other relevant carbon storage data collected in the previous years of the BIFoR experiment, such as leaf area, to further understand where trees will allocate extra carbon under elevated CO2 and provide vital information to understand the future of the global carbon sink.

PhD title: Forest resilience and recovery through the lens of volcanic disturbances.
Year of study: Third 
PhD: With many of the world’s forests under the threat of ecological catastrophe in the wake of anthropogenic agents of change, there is a need now more than ever to understand how forest ecosystems react and recover in the wake of a destructive event. The eruption of Chaitén (Chile) in 2008 and subsequent destruction of neighbouring forest is an opportunity to study how forests re-establish in the wake of disturbance. The work of this project aims to (i) establish primary succession dynamics in this particular ecosystem, (ii) determine if this re-growth is stochastic (random) or deterministic (controlled spatially in some way), and (iii) ascertain the implications of these findings on the wider context of forest recovery in the wake of disturbance.

Novalia Kusumarini
Prof. Sami Ullah, Prof. Iseult Lynch (GEES) and Dr Liam Cox (School of Chemistry).
Year of study: FIrst 
Funded by the Indonesian Government. Novalia is investigating differences in the chemistry of root exudates of newly planted nitrogen-fixing alder (Alnus spp.) and non-nitrogen fixing oak (Quercus spp) saplings in the Mill Haft catchment adjacent of BIFoR-FACE. The key question is to find out whether the two tree types use different strategies for nutrient acquisition. A method for targeted metabolomics of exudates is currently being developed in the School of Chemistry at Birmingham as part of the exudate characterization.  A follow-on experiment on growing oak and alder saplings in the Wolfson Glasshouse under eCO2 will be undertaken to elucidate changes in exudation seasonality, chemistry and amount and how it affects nutrients availability in the soils to guide future forest restoration strategies.

Investigating how changing interactions between humans and elephants affect forest socio-ecological systems in drylands. 
As dryland forests are made venues for wildlife conservation, interactions between human and nonhuman forest users can change. Focusing on interactions between Maasai pastoralists and African elephants in Laikipia, Kenya, my project aims to understand how elephant behaviours have changed with wildlife conservation initiatives in Mukogodo Forest and what affect these changes have had on FSES. By relying on the experiences, observations, and understandings of Maasai pastoralists who embody generations of knowledge about Mukogodo Forest, this project will provide insights into how changing human-nonhuman interactions associated with wildlife conservation initiatives in FSES can affect the material and ontological existence of dryland forests.

PhD title: Study and Fabrication of Rapid Engineered Spectroscopic Technology (FoRESTech) for Identification of Filamentous Pathogens in Leaves
PhD: Ash dieback and oak powdery mildew are devastating pathogens, especially for young trees, and there are currently insufficient techniques to diagnose these infections in the early stages. My project aims to use the non-destructive, versatile analytical technique called Raman spectroscopy to probe the biomolecular changes that occur in the wax and cuticle layers of the leaves of Ash and Oak trees during the course of these infections. The primary goal of the project will be to provide insights into the disease mechanisms of both ash dieback and oak powdery mildew, and then design a handheld Raman spectrometer to allow in-field testing and monitoring of these diseases. Additionally, a study into the effect of elevated carbon dioxide on these disease models will take place such that the device can be used in the BIFoR FACE facility following development.

The experiment being developed consists in a constructed woody wetland where willows will be used, investigating the role of this system on wastewater treatment, biomass production and methane emissions.  Trees can act in a different way from other most used plants in treatment wetlands (for example, macrophytes), since they can remove great amounts of organic matter, Nitrogen, Phosphorus and sequester more carbon that will be imprisoned in their trunks. To minimize CH4 emissions while achieving good nutrient removal, different flow rates will be applied in 6 flumes: steady and intermittent flow; with the last one varying its days of flooded and dry periods. The experiment will start running this spring at the ECOLaboratory.

Info: The effect of enriched atmospheric carbon dioxide on environmental fungi: Despite playing key roles in decomposition, in mycorrhizal associations providing nutrients to plants, and as plant and human pathogens, environmental fungi are notoriously understudied. Measuring the response of fungi to enriched carbon dioxide is an essential component in understanding   how the woodland ecosystem will respond to enriched carbon dioxide. My PhD has two major strands. The first is to characterize the fungal populations at BIFoR FACE, and to measure the variation in these populations temporally. The second aspect is to investigate the effect of enriched carbon dioxide on fungal populations, where I am using environmental sampling from BIFoR FACE in conjunction with laboratory experiments.

PhD: Trees are dying from drought - why care?  Forests are huge stores and sinks of carbon. Droughts will become worse under climate change - more frequent, hotter, and drier.  The extent to which drought plays a role in tree mortality across ecosystems is unknown. This project will use machine learning to find patterns and relationships regarding droughts and forests at a biogeographical level. This scale is most relevant for understanding feedbacks of tree mortality on future climate change.

Clare will use cutting-edge statistical and simulation tools to analyse lab and ecosystem observations of root structure, to elucidate the micro- and mesoscopic physical role of elevated carbon budgets.
