Dr Sarah Crowley delivered the ESI Challenge of the Month talk "The Species in Between: negotiating animal management in a changing world" on Monday 30 September 1 - 2pm in the ESI Trevithick Room. ‌

Do parakeets belong in Britain? Do Scottish wildcats belong in England? Do domestic cats belong outdoors? Much of my work focuses on disagreements and negotiations about which animals belong where, and about whether or how people should intervene in the lives of other species. The subjects of these debates are often ‘liminal’ animals, living on the thresholds between contested categories: native and non-native, wild and domestic, pet and pest. These categories reflect complex human ideas about belonging, which draw on natural and cultural histories, ecological and social interactions, and concerns for the future of disturbed and changing ecosystems. This seminar is based on ten years of research into the social dimensions of managing introduced, reintroduced, and domestic animals in the UK. I will draw on a range of case examples, including protests to protect urban parakeets, scientific debates about the provenance of wildcats and white storks, and neighbourly disputes over outdoor cats. I will explain and explore the concept of species belonging, demonstrate why this matters, and argue that where an animal belongs should always be a matter open to negotiation.

Dr Angela Cassidy, Associate Professor in Science and Technology Studies, took up the ESI Challenge of the Month for October 2024.

Relevant research:

Conflict:

• Why do some scientific controversies take place ‘in public’?  Sometimes, ‘it’s the politics, stupid’ argument isn’t really about ‘the science’. by Dan Hicks argues this is the case with GMOs, vaccine debates and climate change. [Hicks, D. J. (2017). Scientific Controversies as Proxy Politics. Issues in Science & Technology, 33(2)].
• ‘Science push.’ Scientists put work into public communication for lots of reasons. In the case of ev-psych, it was to help them establish legitimacy, which they did not have inside psychology. Scicomm is a  multidirectional conversation! [Cassidy, A. (2006). . Public Understanding of Science, 15(2), 175-205].
• ‘Media pull.’ At the same time, a (literally) sexy subject helps. Why media loved evolutionary psychology? Gender essentialism and public dust-ups sell! [Cassidy, Angela. 2007. ‘.’ History of Psychology 10(2):199–226]

Co-existence:

• Public controversy over Bovine TB and badger cull involves politics, science push, media pull AND a*very long backstory. This public scientific controversy has been going on for over 50 years, and in the UK, we’ve been arguing about badgers for a lot longer than that: [Cassidy, Angela. 2019.  Cham, Switzerland: Palgrave Macmillan; Springer International. 

The oldest historical source used for this research is the Exeter Book (scanned and made available online by Exeter Digital Humanities, with the original found at the Exeter Cathedral), which dates to c. 970 AD.  is tells the story of a hunted animal defending its family in a ‘hole in the hill’ and is generally thought to be about badgers.

• At the same time, people love to feed other animals, often because we foster care and social connections with others by sharing food. Anthropologists call this ‘commensality’, while zoologists think about ‘commensalism’ and its importance for domestication processes. Dr Cassidy is part of the , funded by the Wellcome Trust. It explores the causes and consequences of people feeding other animals in past and present.

The project team have created a  which is being exhibited at the Museum of English Rural Life (MERL) in collaboration with the artists Rebecca Jewell and and Sandy Sykes.

Collaboration

• Given that disciplinary specialists and human/nonhuman co-existence can turn so easily towards conflict, how to regear to collaboration? The RENEWing Biodiversity partnership is exploring this question at multiple levels: /. 

 starts from the proposition that to address the biodiversity crisis we’re in with due urgency, we need to turn traditional conservation logic inside-out and place ‘.’ RENEW has ground breaking collaborations: National Trust as Co-Investigators, over 30 non-academic partners, Social Science and Humanities researchers on equal terms with natural scientists and a shared research agenda. Dr Cassidy is Co-Investigator for the X3 Collaboration in Practice theme, exploring how interdisciplinarity works everyday.

• Environmental scientists have been trying to do this since the 1960s. For example, the  in the 1980s, stitching the planet back together via interdisciplinary research.  Are we reinventing the wheel?  Our research is finding out via collaboration with the British Library Oral History department.
•  uses 'embedded STS' approach, studying collaboration in real time, making creative interventions to help people build relationships, think across disciplines, reflect on practices and explore care for each other and biodiversity.
• The RENEW project also makes practical recommendations, based on research and 'grey' policy literature along with first-hand accounts. For example, start with a shared research agenda rather than expecting some disciplines to solve the questions and problems defined by another.  .

Dr Angela Cassidy delivered the ESI Challenge of the Month talk "Conflict, Co-existence and Collaboration" on Monday 21 October 1 - 2pm in the ESI Trevithick Room.

Why do we have academic disciplines and what happens when they disagree? How do people co-exist with other animals? Can interdisciplinarity work?  These are the kinds of challenge I engage with in my research, which is all about science, borders, boundaries and the spaces in-between. The talk will start with the theme of ‘Conflict’, exploring public knowledge controversies and drawing out how and why some scientific disagreements are played out in the wider public sphere, using evolutionary psychology and bovine TB as examples. The case of badger/TB (alongside a small bestiary of other examples) will in turn be used to think through the historical dynamics of controversies; how human-animal relationships have changed over the past century; and how food may be key in shifting relations from conflict to co-existence. Finally, I will reflect upon my ongoing work investigating interdisciplinarity – research that reaches beyond disciplinary boundaries. Drawing upon oral histories of collaborative experiences, combined with our team’s ‘embedded’ study of interdisciplinarity in the RENEW(ing) Biodiversity project, I will outline practices that help people work together across multiple fields of expertise, and key factors that can block their paths.

Dr Hampson's three large interdisciplinary research grants (£1.3 million in total) were and are supported by Indigenous groups and government bodies, and they continue to have international impact. Here is a recent grant award:

• Dr Jamie Hampson has been awarded £225,000 as a Co-PI with physicist Dr Tessa Charles (University of Liverpool/ Australian Synchrotron) and archaeologist Dr Courtney Nimura (Ashmolean Museum, Oxford) on a UKRI Biotechnology and Biological Sciences Research Council interdisciplinary project.
  NoMAD (Non-destructive Mobile Analysis and imaging Device) draws on technology developed for particle accelerators to bring scientific analysis techniques to Indigenous rock art and other remote heritage sites. The project focuses on rock art – a crucial part of our shared global cultural heritage – and the design and development of a portable particle accelerator. This project is a world-first, revolutionary in the fields of physics and cultural heritage management.

Dr Jamie Hampson delivered the ESI Challenge of the Month talk "Images of power: why should we care about Indigenous rock art?" on Monday 25 November 1 - 2pm in the ESI Trevithick Room.

Sacred Indigenous rock paintings and engravings are found in different landscapes in almost every country around the world. Some motifs are at least 75,000 years old; some were painted yesterday.

We do not always know exactly what the rock imagery means, but thanks to intertwining strands of evidence we do know a great deal – especially in regions where the descendants of the original artists still survive. Indeed, rock art motifs were – and often still are – ‘powerful things in themselves’, and an integral part of sacred Indigenous heritage. Tragically, however, rock art in some parts of the world is threatened by industrial development and climate change.

In this talk, I draw from 25 years of archaeological and anthropological fieldwork in southern Africa, the Americas, and Australia.

Dr Laura Colombo, Senior Lecturer in Sustainable Futures, took up the ESI Challenge of the Month for February 2025.

Relevant research:

The Â鶹ֱ²¥ has been a pioneer in working towards bridging the ecology - business studies divide. Dr Laura Colombo is the Programme Director for the interdisciplinary BSc Business and Environment programme. The programme is built on: Sustainable business, Environmental science and Environmental justice.

"What are business schools for? Who are they for? For what future?" Sophie talks to Dr Laura Colombo about the need to transform management education for a sustainable future. Listen to the  now.

Some relevant work by colleagues in the space of bridging business and ecology:

•  clearly and unequivocally states that business-as-usual contributes to environmental crises because of its focus on profit. How can business studies learn from natural system processes to enhance value creation and better steward the natural environment?
•  argues that the organisation studies can no longer ignore the current global climate emergency. How does the discipline need to be rethought in a world approaching 50 degrees? 
•  argues that incremental and accommodative forms of responsible management learning and education are at odds with the urgency, nature, and magnitude of the climate crisis, and calls for “radicalising” management education.

Dr Laura Colombo's recent research on this topic:

•  discusses how business schools can transform to address the pressing social and ecological challenges of our time. Drawing on insights from social-ecological systems and social innovation research, this article argues that management education must shift from a narrow focus on market efficiency to a broader, civic-oriented approach.
•  calls for the development of a social-ecological approach to management learning and education, considering business, society, and nature as nested systems: without society, there is no business; and without nature, there is no society, hence no business. This has important implications for how and what we teach in business schools.

Dr Colombo delivered the ESI Challenge of the Month talk "Bridging the Divide: Integrating Ecology and Business for a Sustainable Future" on Monday 27 January 1 - 2pm in the ESI Trevithick Room.

As Kenneth Boulding famously quipped: “Anyone who believes that growth can go on forever is either a madman or an economist.” Ecological economics has long recognised that the economy cannot be considered in isolation from the social and environmental systems in which it is embedded. After all, as their shared etymological roots remind us, the words “economy” (oikos + nomos) and “ecology” (oikos + logos) are linguistic siblings.

While a dialogue between ecology and economics has long been established, business studies have largely remained estranged from this conversation. However, this is beginning to change. In recent years, in management and organisation studies scholarship, there has been a growing recognition that business  – like all human activity – is embedded in, and dependent upon, complex living systems. This realisation carries profound implications for what and how we teach in business schools. Yet, much of this territory remains uncharted.

This month’s challenge is an invitation for ecologists and business scholars to come together. Forty-three years after the Symposium on “Integrating Ecology and Economics” laid the foundation for ecological economics, it is time to ask: how can we integrate ecology and business studies? What can business learn from ecology, and what might ecology learn from engaging with business?

Dr Chris Kaiser-Bunbury delivered the ESI Challenge of the Month talk "On the art of conserving pollinators: the role of gardeners" on Monday 31 March 1 - 2pm in the ESI Trevithick Room.

Insect pollinators are in decline worldwide, threatening global food production and the diversity of plant communities that depend on pollinators for reproduction. As a conservation ecologist using interaction networks to understand the impact of pollinator decline on ecological communities, my research aims to understand how we can best halt the erosion of insect abundance and diversity. While our ability to monitor changes in pollinators and pollination in human-modified landscapes is essential for effective management and protection, the engagement and actions of the general public potentially have the biggest impact on pollinator diversity in such landscapes.

Residential gardens are now known to be important refuges for pollinators, as agricultural lands are becoming increasingly hostile environments for these beneficial insects. The challenge is to engage and empower residential gardeners in managing these important habitats for pollinators.

I will present an exciting interdisciplinary approach to address the pollinator crisis. Our new project explores the power of art and algorithm-derived planting designs to create networks of optimal foraging habitats for pollinators across a semi-urban environment and studies the role that garden owners can play in actively supporting and monitoring pollinators in their gardens. The project combines art, social science, philosophy and ecology to improve pollinator diversity in residential gardens and transform human-nature interactions by enabling gardeners to engage in evidence-based methods for biodiversity conservation.

Dr Bridget Watson delivered the ESI Challenge of the Month talk "Growing plants sustainably: harnessing the power of the soil microbiome" on Monday 2 June 1 - 2pm in the ESI Trevithick Room.

Growing sufficient food to feed the world is a huge task, especially when faced with a growing population and the unpredictability that comes with climate change. However, many current agricultural practices can be damaging to the environment, as intensive farming can deplete soils, reducing soil fertility. In addition, the use of synthetic fertilisers and pesticides can pollute water ways. Going forward, agricultural production must become more sustainable to ensure that the land can continue to provide for future generations. Addressing this complex challenge will require a multifaceted approach, but focusing on the microorganisms in the soil and harnessing their ability to support plant growth will be a key component.

My research focuses on soil microbes that naturally support plant health and aims to bridge gaps in our understanding of plant-microbe interactions so we can effectively use microbes as tools for sustainable agriculture. More specifically, I study beneficial soil bacteria from the Azospirillum genus, alongside wheat and related plants, as a model system to understand the mechanisms underpinning how bacteria promote plant growth. Further, my work examines how bacteria evolve and adapt in the dynamic soil environment, plus how plant-bacteria interactions are influenced by various factors in the complex soil environment.

Dr Jonathan Bennie (Department of Earth and Environmental Science), had taken up the ESI Challenge of the Month for November 2025. He delivered the talk "Shifting grounds: rethinking conservation in an age of rapid climate change" on Monday 24 November 1.30 - 2.30pm in the ESI Trevithick Room.

.

At the turn of the 21st Century, ecologists estimated that between 15 and 37% of species will be ‘committed to extinction’ by 2050 due to climate change, if urgent action was not taken to curb greenhouse gas emissions. This represents a major acceleration of the biodiversity crisis, compounding ongoing losses due to resource exploitation and land use change. In 2025 we are now halfway through the timescale of those predictions, and there is indeed mounting evidence that as species change their distributions to track a changing climate, local extinctions are occurring, new species arriving, and novel ecosystems are developing. These processes challenge existing conservation paradigms which are often strongly based in a sense of place – we put special value on native species and ecosystems, traditional cultural landscapes and human values and attachments to familiar environments. As efforts to curtail emissions fall short of the action required to stabilise global temperatures below 1.5 degrees (and likely 2 degrees), I review what we understand about the ecological changes that are occurring, and ask how we might deal with understanding and managing environmental change and loss. This is a talk in two halves – in the first I will describe research on how species and ecosystems are predicted to respond to climate change and the evidence for these changes. In the second I will describe some recent work with the Adaptive Heritage Practice Lab (AHPL) collective exploring how in a rapidly changing world, conservation practices might become more flexible and responsive to changing conditions.

Professor Catherine Leyshon (Department of Earth and Environmental Science), had taken up the ESI Challenge of the Month for January 2026. She delivered the talk "Where is Everybody? Finding and supporting the smallest voluntary sector organisations" on Monday 26 January 1 - 2pm in the ESI Trevithick Room.

.

This talk examines the challenges and opportunities facing small voluntary and community organisations in England. Using the metaphor of the "microbiome," it highlights how the smallest voluntary sector organisations—comprising an estimated 335,000 unregistered groups alongside 132,000 registered ones—are essential components of public service delivery, community support, and care for the environment. And yet we have no true idea of how many of these organisations there are, where they are, or how they help. The current estimates of the size and shape of the voluntary sector are based on extrapolation. This has implications at the local and national level: it is currently not possible to understand the range of and gaps in provision across Cornwall or advocate powerfully for the value of the voluntary sector at a national level. This talk covers what might be done about this, and how the question of finding the microbiome leads into a wider national conversation about the quality and consistency of the data we have on the voluntary sector.

His greatest passion in life is natural history and he is also an award-winning photographer.

Professor Charles Tyler delivered the talk "A Wildlife Safari through Dartmoor’s  varied Habitats  (peppered with a touch of science)" on Monday 23 March 1 - 2pm in the ESI Trevithick Room.

Dartmoor is a hugely important local area for wildlife including for some of our nationally  declining breeding bird species. The topography and climate on ‘the moor’ create varied habitats and these,  in turn , support a wonderful array of both resident and migratory  wildlife species.  This talk will take you on photographic safari through some of  the moors varied habitats and wonderful wildlife, much of which you may not have seen before, even if you frequent the moor. The narrative will largely  draw on  observations from Charles’s wanderings on the moor over a period of more than 2 decades, but- given the audience-  it will also be  peppered with some more learned scientific facts! He will illustrate how his  wanderings and observations have led to PhD research projects in Biosciences that have included harnessing citizen science to help support  conservation of some of Dartmoor’s ground nesting birds, including his obsession - the Cuckoo!
