Capturing change in ecosystem service delivery from coral reefs
Ecosystems around the world are changing due to interacting local and global stressors. These changes are likely to affect ecosystem services - the benefits that ecosystems contribute to human wellbeing - but the complexity of social-ecological processes underpinning these services limits our understanding change. In this thesis, I examine changes in ecosystem services associated with climate-impacted tropical coral reefs and implications for the wellbeing of coastal communities. I draw on empirical data from the Seychelles, where two mass bleaching events (1998, 2016) have affected benthic and fish community composition. I first provide an overview of coral reef ecosystem services research and use empirical interview data from tourism and fishery key informants to understand the social-ecological aspects of services at the level of the service provider. This reveals the complexity of service providers underpinning locally valued services and benefits, but also the advantages of dis-aggregating service providers and their traits to understand how services are likely to respond to environmental change. Shifting from conceptualisations of change to lived experiences of change, I then explore how changes in ecosystem services are perceived by coral reef fishers. Changes have been perceived, though perceptions differ according to fishers’ characteristics, and have implications for the material, relational and subjective dimensions of fishers’ wellbeing. Finally, I draw on a social wellbeing approach to examine how the marine environment, and changes therein, affect fishers’ understanding of and ability to live well. This reveals tensions in fishers’ ability to pursue wellbeing, shaped by the social-ecological context in which changes to nearshore environments occur. These findings have implications for how changes in ecosystem services are investigated and highlight the need for multiple disciplinary perspectives to better understand the consequences of environmental change for human wellbeing
Coral reef ecosystem services in the Anthropocene
Coral reefs underpin a range of ecosystem goods and services that contribute to the well‐being of millions of people. However, tropical coral reefs in the Anthropocene are likely to be functionally different from reefs in the past. In this perspective piece, we ask, what does the Anthropocene mean for the provision of ecosystem services from coral reefs? First, we provide examples of the provisioning, regulating, cultural and supporting services underpinned by coral reef ecosystems. We conclude that coral reef ecosystem service research has lagged behind multidisciplinary advances in broader ecosystem services science, such as an explicit recognition that interactions between social and ecological systems underpin ecosystem services. Second, drawing on tools from functional ecology, we outline how these social–ecological relationships can be incorporated into a mechanistic understanding of service provision and how this might be used to anticipate future changes in coral reef ecosystem services. Finally, we explore the emergence of novel reef ecosystem services, for example from tropicalized coastlines, or through changing technological connections to coral reefs. Indeed, when services are conceived as coming from social–ecological system dynamics, novelty in services can emerge from elements of the interactions between people and the ecosystem. This synthesis of the coral reef ecosystem services literature suggests the field is poorly prepared to understand the changing service provision anticipated in the Anthropocene. A new research agenda is needed that better connects reef functional ecology to ecosystem service provision. This research agenda should embrace more holistic approaches to ecosystem service research, recognizing them as co‐produced by ecosystems and society. Importantly, the likelihood of novel ecosystem service configurations requires further conceptualization and empirical assessment. As with current ecosystem services, the loss or gain of services will not affect all people equally and must be understood in the context in which they occur. With the uncertainty surrounding the future of coral reefs in the Anthropocene, research exploring how the benefits to people change will be of great importance
The Metropolis and Evangelical Life: Coherence and Fragmentation in the ‘Lost City of London’
This article examines the interplay of different processes of cultural and subjective fragmentation experienced by conservative evangelical Anglicans, based on an ethnographic study of a congregation in central London. The author focuses on the evangelistic speaking practices of members of this church to explore how individuals negotiate contradictory norms of interaction as they move through different city spaces, and considers their response to tensions created by the demands of their workplace and their religious lives. Drawing on Georg Simmel’s ‘The Metropolis and Mental Life’, the author argues that their faith provides a sense of coherence and unity that responds to experiences of cultural fragmentation characteristic of everyday life in the city, while simultaneously leading to a specific consciousness of moral fragmentation that is inherent to conservative evangelicalism
Towards a holistic understanding of non-native tree impacts on ecosystem services : A review of Acacia, Eucalyptus and Pinus in Africa
Fast-growing, stress-tolerating tree species belonging to the genera Acacia, Eucalyptus and Pinus have historically been introduced to many tropical and sub-tropical regions to support various economic and environment-regulating functions. While these non-native tree (NNT) species are often highly useful, many are simultaneously invasive, generating negative environmental impacts. Current knowledge regarding the impacts of these NNTs on the ecosystem services (ES) that affect human well-being is largely informed by South African research, which inhibits a broader understanding of the contributions of these trees to those services. Acacia, Eucalyptus and Pinus have been widely introduced globally, yet very little is known about their contribution to ES in many locations. Here, we aimed to summarise the evidence for Acacia, Eucalyptus and Pinus as generating benefits and harm to ES, focusing on sub-Saharan Africa outside of South Africa. We conducted a literature search using the ISI Web of Science, which yielded 125 relevant publications. Although the three genera were reported to affect key ES in sub-Saharan Africa, the data were limited in geographic scope, with a strong bias towards East Africa as well as biases towards certain species and ecosystem service. The benefits of these NNTs relative to their costs are context dependent and may not reflect their actual impacts on ES in sub-Saharan Africa. Our review highlights the need for more systematic research from a broader perspective to manage potential conflicts and guide better management prioritisation

A mixed methods PAR study investigating social capital as a resource for Black and other racially minoritised communities in the UK:A study protocol
Understanding how different Black and other racially minoritised communities thrive is an emerging priority area in mental health promotion. Literature demonstrates health benefits of social capital (social resources embedded within social networks). However, its effects are not always positive, particularly for certain subpopulations who are already disadvantaged. The CONtributions of social NEtworks to Community Thriving (CONNECT) study will use Participatory Action Research (PAR) to investigate social capital as a resource that benefits (or hinders) racially minoritised communities and their mental health. The CONNECT study was designed within a partnership with community organisations and responds to local policy in two South-East London Boroughs, thereby providing potential channels for the action component of PAR. Taking an anti-racism lens, we acknowledge the underpinning role of racism in creating health inequities. We apply an intersectional framework to be considerate of overlapping forms of oppression such as age, gender, socioeconomic status, and sexual orientation as an essential part of developing effective strategies to tackle health inequities. Key components of this mixed methods PAR study include (1) involving racialised minority community members as peer researchers in the team (2) collecting and analysing primary qualitative data via interviews, photovoice, and community mapping workshops, (3) developing relevant research questions guided by peer researchers and collaborating organisations and analysing secondary quantitative data accordingly, (4) integrating qualitative and quantitative phases, and (5) working closely with community and policy partners to act on our findings and use our research for social change. The PAR approach will allow us to engage community (voluntary sector and government) and academic partners in decision making and help address imbalances in power and resource allocation. Knowledge generated through this collaborative approach will contribute to existing community initiatives, policies, and council strategies. This will ensure the views and experiences of racially minoritised communities drive the changes we are collaboratively committed to achieving.<br/
Epidemiology and Clinical Features of Patients with Visceral Leishmaniasis Treated by an MSF Clinic in Bakool Region, Somalia, 2004–2006
Our paper describes the epidemiological features of visceral leishmaniasis in the Bakool region, South Central Somalia, over the years 2004 to 2006. Since 2000, Médecins Sans Frontières has been providing care for patients suffering from visceral leishmaniasis in Huddur, located in a region endemic for visceral leishmaniasis. By the end of 2005, we witnessed a dramatic increase in the number of patients admitted to the Huddur centre with visceral leishmaniasis. In our paper, we provide a description of the profile of patients admitted, thus giving an insight into the epidemiology of visceral leishmaniasis in a part of the world where relatively little has been documented and where the true magnitude of this neglected disease remains unknown
Solving the border control problem: evidence of enhanced face matching in individuals with extraordinary face recognition skills.
Photographic identity documents (IDs) are commonly used despite clear evidence that unfamiliar face matching is a difficult and error-prone task. The current study set out to examine the performance of seven individuals with extraordinary face recognition memory, so called “super recognisers” (SRs), on two face matching tasks resembling border control identity checks. In Experiment 1, the SRs as a group outperformed control participants on the “Glasgow Face Matching Test”, and some case-by-case comparisons also reached significance. In Experiment 2, a perceptually difficult face matching task was used: the “Models Face Matching Test”. Once again, SRs outperformed controls both on group and mostly in case-by-case analyses. These findings suggest that SRs are considerably better at face matching than typical perceivers, and would make proficient personnel for border control agencies
The potential role of thioredoxin 1 and CD30 systems as multiple pathway targets and biomarkers in tumor therapy
Our progress in understanding pathological disease mechanisms has led to the identification of biomarkers that have had a considerable impact on clinical practice. It is hoped that the move from generalized to stratified approaches, with the grouping of patients into clinical/therapeutic subgroups according to specific biomarkers, will lead to increasingly more effective clinical treatments in the near future. This success depends on the identification of biomarkers that reflect disease evolution and can be used to predict disease state and therapy response, or represent themselves a target for treatment. Biomarkers can be identified by studying relationships between serum, tissue, or tumor microenvironment parameters and clinical or therapeutic parameters at onset and during the progression of the disease, using systems biology. Given that multiple pathways, such as those responsible for redox and immune regulation, are deregulated or altered in tumors, the future of tumor therapy could lie in the simultaneous targeting of these pathways using extracellular and intracellular targets and biomarkers. With this aim in mind, we evaluated the role of thioredoxin 1, a key redox regulator, and CD30, a cell membrane receptor, in immune regulation. Our results lead us to suggest that the combined use of these biomarkers provides more detailed information concerning the multiple pathways affected in disease and hence the possibility of more effective treatment
