The Rediscovery of a Challenger Expedition Specimen in William Herdman’s Zoology Museum Collection at the University of Liverpool (and how digitisation is transformative).

Written by Leonie Sedman, Curator of Heritage & Collections Care, University of Liverpool.

Along with many other NatSCA members, I care for a mixed collection, meaning that one inevitably becomes something of a ‘Jack of all trades’ missing out on the academic satisfaction created by specialisation. As a curator who finds collections research to be the most satisfying part of my job, it can be frustrating when that research is often only possible on a ‘need-to-know’ basis – usually when a new display or exhibition is being planned, or when the specimens are to be used in teaching. Looking on the bright side though – this does provide glimmers of joy when the research produces something exciting!

In 2004 when I was first employed to manage the University of Liverpool’s Heritage Collections (medical & scientific museum collections built up through research or teaching), I retrieved a large proportion of the collections from attics and cellars where they languished because the objects and specimens were no longer actively used in teaching (this is now changing – but that would be a different blog). The Zoology Museum collection was one of these.

“Our Irish Natural History”: Increasing the Accessibility of Natural History Collections through Community-Driven Interpretation

Written by Adriana Ballinger, Yale University Charles P. Howland Postgraduate Research Fellow at the National Museum of Ireland, Natural History.

Natural history specimens are often inaccessible to the communities from which they were collected. As a result, source communities lack opportunities to connect with elements of their local heritage, and museums and their publics overlook the place-based expertise that many of these communities hold about the specimens we research and see on display. Scientists lead the knowledge creation process surrounding natural history specimens, but source communities can also contribute valuable information, especially regarding the meanings that flora, fauna, and geological features embody in their environments of origin. Although these cultural contexts are often intangible and unquantifiable, they are nevertheless important facets of specimens’ natural histories. For the past year, I have led “Our Irish Natural History,” a community-driven research and exhibition project at the National Museum of Ireland (NMI). I set out to increase the accessibility of the NMI’s natural history collections, explore innovative avenues for community-led interpretation, and create new opportunities for public engagement.

Seeing With Their Eyes A Poetic Reflection on the 2025 ‘From Collections to Connections’ NatSCA Conference Presentation

Written by Pauline Rutter – Independent Archival Artist, Community and Organisation Poet.

These words look out from the page with eyes I have borrowed. Eyes not shaped for vision through the specific disciplinary scientific lens. Eyes that strain to see beyond past centuries of debate on what, of all origins, is knowable and what is not. With these original eyes, would ways of seeing allow the light to travel outwards resisting funnelled perspectives and interpretations descended from imperialistic systems of Enlightenment science, colonial ideologies and narratives? In this context my eyes had opened up unevolved or re-evolved with lepidopteran vision, though not removed from all that had been taught to be seen. New eyes with sight of intensified colour that amplified nature’s interconnecting patterns, only visible outside the spectrum of the everyday, the expected, the predetermined. 

What use is butterfly sight that transforms configured objects and living matter with or without full binominal species names, into fragments like those of the intertwined and metamorphosed elements in ritualistic rapture spreading out across a Wangechi Mutu collage?

How to Foster Empathy with Endangered Animals: Developing a Creative Writing and Drawing Workshop Toolkit

Written by Dr Christina Thatcher, Lecturer in Creative Writing & Dr Lisa El Refaie, Reader in Language and Communication, Cardiff University.

With biodiversity declining at an alarming rate, we need to find ways of encouraging people to care about all endangered animal species, not just the ones with the most obvious appeal, such as pandas and polar bears, for example. According to the International Union for Conservation of Nature’s ‘Red List of Threatened Species’, 27% of mammals are threatened with extinction, but so are 44% of reef corals, 41% of amphibians, 37% of sharks and rays, 21% of reptiles, and 12% of birds.

In 2023, we—Dr Christina Thatcher and Dr Lisa El Refaie from Cardiff University—met and discovered our shared interest in the expressive arts, metaphor, empathy and nature. We then designed a project which aimed to use the power of creativity to increase public awareness of, and empathy for, endangered animals, focusing on species that have few or no obvious human-like features. The project was funded by the Arts and Humanities Research Council (AHRC) Impact Acceleration Account and ran from November 2023 until the autumn 2024, in collaboration with Natural History curators at the National Museum Cardiff.

Feeling Older than Your Age? The Importance of Museum Collections for Radiocarbon Dating, and a Request for Collections containing Bivalves Collected Before 1950 from the UK

Written by Rachel Wood, Associate Professor, Oxford Radiocarbon Accelerator Unit, School of Archaeology, University of Oxford.

Radiocarbon dating is routinely used to work out the age of archaeological and palaeontological sites, and often pops up in news articles and TV dramas. But some substantial problems remain. One of these is the calibration process, which allows us to convert the ratio of 14C (“radiocarbon”) and 12C (the common stable form of carbon) to an age estimate. This is particularly challenging when we are trying to date marine shells or any animal that has eaten food from the marine system. This means that it can be difficult for us to get an accurate age for a sample that should be straightforward – for example, the skeleton of Medieval person or a Mesolithic dog.

The Oxford Radiocarbon Accelerator Unit is starting a project looking for samples of marine shells to help resolve this problem (Fig. 1). Natural history collections in museums are key to its success, and we would be very grateful to hear if anyone has a collection of pre-1950 marine bivalve shells.

The Problem

At school, we are taught that radiocarbon dating works because radiocarbon decays radioactively at a known rate. By comparing the amount of 14C to a stable form of carbon called 12C, we can work out the age of a sample (Fig. 2). This is true, but only partially so because the starting 14C:12C varies. To get around this problem, we need to calibrate radiocarbon dates. Most 14C is produced in the upper atmosphere, and is incorporated into plants by photosynthesis and then passed through the food chain. This means, that if someone is eating terrestrial food – they will have a similar 14C:12C ratio in their bodies as in the atmosphere.
