Of Jumping Mice and Megalosaurus

CELEBRATING THE RECENT ACQUISITION OF AN IMPORTANT ARCHIVE

By Danielle Czerkaszyn, Librarian and Archivist and Grace Exley, AHRC Doctoral Student

200 years since the first scientific description of a dinosaur, the Museum has welcomed a significant archival collection relating to the man who introduced us to Megalosaurus, William Buckland (1784-1856). The archive contains over 1,000 items including letters, notebooks, family papers, prints, and artworks. It joins the Museum’s existing Buckland archive, as well as more than 4,000 geological specimens, and helps fill in the knowledge gaps surrounding the life and work of Oxford’s first Reader in Geology and Mineralogy. Not only is there the potential to learn more about Buckland’s early life as a student at Christ Church, there is also material relating to the wider Buckland family, including his son, the zoologist Francis Trevelyan Buckland, and wife, the naturalist Mary Buckland (née Morland, 1797-1857).

Among the 70 letters in the archive that are addressed to Mary, there is correspondence from chemist William Wollaston, Scottish polymath Mary Somerville, and a lively letter from John Ruskin, explaining to Mary his disgust at all things marine:

“I dont [sic] doubt that those double natured or no-natured salt water things are very pretty alive, but they disgust me by their perpetual gobbling and turning themselves inside out and on the whole I think for purple and rose colour & pretty shape, I may do well enough with convolvulus’s [sic] & such things which dont [sic] eat each other up, backwards & forwards all day long.”

Ruskin was clearly teasing his friend, as molluscs happened to be Mary’s specialist subject!

The collection also contains two sketchbooks belonging to Mary, one of which dates from June 1817, seven years before her marriage to William and contains exquisite ink and watercolour illustrations of natural history specimens.

Fulgurite, or, as Mary called it a ‘vitrified sand tube’. These form when lightning strikes the ground, particularly sandy surfaces. Similar examples are present in the remains of Mary’s mineral collection, held by OUMNH.

The sketchbook gives us a rare glimpse into how a nineteenth-century woman learned about natural history.  The book contains copied passages from natural history texts, enabling us to trace what Mary was reading. Her interests spanned geology and mineralogy, and she also included pieces on zoological curiosities and even polar exploration. She read and copied extracts from a variety of sources, some of which – George Shaw’s Zoological Lectures, for example – were intended to suit a lay-audience (as Shaw put it, intended as a “familiar discourse with Lady-Auditors”). However, other elements of her reading were probably never intended for a woman like Mary — she also copied passages from the Transactions of the Geological Society even though women could not join as Fellows until 1919. As archival materials relating to women are often sparse, this is a truly rare and incredibly valuable insight into how Mary used her connections to access resources and the techniques she used to teach herself about natural history.

Perhaps the most striking feature of the notebook is its intricate, exquisite illustrations. These, done in watercolour, ink, and pencil, are reproductions of the figures from the works Mary copied out. A favourite in the sketchbook is the “Canadian Jumping Mouse”, a long-tailed rodent described in a piece in the Transactions of the Linnaean Society by Major General Thomas Davies in 1797. There are also many representations of molluscs (detailed enough to repulse Ruskin), mineral specimens, and occasional fold-out geological sections. As we flick through the book, we can see Mary experimenting with media and techniques — not only developing as an artist but also honing her skills as a scientific illustrator.

The skills and knowledge Mary developed in her natural history notebook were crucial to her later collaboration with William, as well as her own independent work as a draughtswoman before her marriage. In 1824, when Buckland presented the jaw of Megalosaurus to the Geological Society, it was “M. Morland” who provided the painstakingly detailed plates. Research has begun to uncover the extent of Mary’s work as a naturalist and illustrator, and now, with the help of the materials in the newly acquired archive, we can explore the origins of her skills. The archive is currently in the hands of a Paper Conservator, Anna Español Costa, to ensure the material is kept in the best condition for many years to come. Items from the archive will feature in the Breaking Ground exhibition, opening in October 2024.

Our fundraising campaign saw us receive generous support from the National Heritage Memorial Fund, Arts Council England/V&A Purchase Grant Fund, Friends of the National Libraries, Headley Trust, and other private donors. Additionally, in late 2022, we launched the Buckland Papers Appeal, asking members of the public to help us meet our target to purchase the archive. Thank you to all our funders and members of the public who responded to our call. We could not have raised the money so quickly without your support and we are now thrilled to share the archive with you all.

Wasp Faces: Power Struggles and Royal Drama

By Kristian Suszczenia, Intern

The second you step into the Museum of Natural History you will notice a remarkable thing about nature: its diversity. Instantly, you see huge whale bones, a distant elephant skull, birds, fish, dinosaurs, and a mounted kaleidoscope of colourful insects. This variation is what many of us love most about biology.

But diversity occurs at a much finer scale than the magnitudes of difference that exist between species. Often there is ‘Individual Variation’ — differences that occur within species. Person to person, specimen to specimen, each organism is unique, just like us humans!

Polistes wasps in the Collections at OUMNH

Buried under the 5 million other insects of the HOPE collection is a drawer that houses a species of the genus Polistes, a social paper wasp collected from Brazil. A close look at their faces reveals staggering individual variation. Before getting confirmation from specialists, the Museum staff found it hard to believe that these four faces could even belong to the same species. The question is, why are they so different? Is there an evolutionary benefit to all these wasps having their own style of eyeliner?

Variation in the faces of paper wasps

It is well-known that individual variation can give certain members of a species an edge over others, especially when it comes to dating! From guppies to fruit flies, females often prefer mates that stand out with unique colours and patterns, perhaps because they are simply more noticeable.

Yet dating is not a sufficient explanation for our fashionable paper wasps. They get a very different benefit from their unique looks — not so much standing out, but being memorable. For them, a memorable identity is a way to remember who goes where in a critical pecking order.

Thanks to a lot of elegant work by Polistes specialists, we understand that bespoke face markings tend to evolve in species that have multiple queens in a linear hierarchy. A Polistes queen can start a hive alone but often benefits from forming a group of queens that can all cooperate together in a single hive. In order to cooperate, the queens must decide on a dominance hierarchy amongst themselves. To do this they take part in brutal one-on-one battles as they assess each other’s prowess.

After they establish an initial order, each wasp will constantly test the adjacent ranks (their closest match) with darts and lunges as they try to climb the ladder for extra reward and simultaneously defend their place. Four punishes Three for transgressions and plots against Five’s downfall. It’s a royal reality show.

This part-insect, part-spartan society is certainly fascinating, but what does it have to do with the wasps’ faces?

In order for queens to defend their rank from their adjacent competitors, they need to know exactly who’s who. Unique faces are more recognisable and more memorable. Being able to recognise and recall every individual wasp allows queens to track their rivals based on their faces and avoid a lot of violent misidentification. Imagine if a queen were to look forgettable; every other queen in the hive would see her as a potential challenge to their power. She wouldn’t last long. But having a memorable face allows individuals to avoid unnecessary scraps and make for a more efficient hive overall.

After learning the story of the wasps, it seems plausible that humans may have evolved our fantastically recognisable faces for societal advantages too — perhaps to avoid getting mistaken for an enemy, perhaps so we can trade favours, or maybe just to avoid general confusion. It would certainly make life difficult if all your co-workers had the exact same face. Remembering names is hard enough already!

Four Museum staff willing to volunteer their faces!

A.R. WALLACE’S ARCHIVE NOW AVAILABLE ONLINE

“In all works on Natural History, we constantly find details of the marvellous adaptation of animals to their food, their habits, and the localities in which they are found.”

– A.R. Wallace

2023 marks a number of important anniversaries in the UK: it has been 75 years since the founding of the NHS and the arrival of the Empire Windrush in London, and 100 years since the first outside broadcast by the British Broadcasting Company. Importantly for the Museum, it is also the 200th anniversary of the birth of Alfred Russel Wallace (1823-1913), the trailblazing biologist, geographer, explorer, and naturalist.

Wallace was one of the leading evolutionary thinkers of the nineteenth century and is most well-known for independently developing the theory of natural selection simultaneously with Charles Darwin. The publication of Wallace’s paper “On the Tendency of Varieties of Depart Indefinitely from the Original Type” in 1858 prompted Darwin to quickly publish On the Origin of Species the following year. He was a pioneer in the field of zoogeography and was considered the leading expert of his time on the geographical distribution of animal species. He was also one of the first scientists to write a serious exploration of the possibility of life on other planets.

Wallace undertook extensive fieldwork in the Amazon River basin and the Malay Archipelago. He spent four years in the Amazon from 1848-52 but unfortunately lost much of his collection when the ship he returned to Britain on caught fire. Afterwards, he spent eight years in the Malay Archipelago (1854-62), building up a collection of 125,660 specimens including 109,700 insects, many of which are currently housed at Oxford University Museum of Natural History. In fact, we now hold one of the largest collections of Wallace specimens in the country.

Psychonotis caelius (small green banded blue butterfly) collected by A.R. Wallace

In addition to entomological specimens, OUMNH holds a large and varied archival collection relating to Wallace. The archive includes original insect illustrations sent to Wallace by contemporary entomologists, photographs, and even obituaries. By far the largest portion of the collection is 295 letters of correspondence, of which 285 were penned by Wallace himself. The bulk of Wallace’s letters were written to fellow scientists, including the chemist and naturalist Raphael Meldola and the evolutionary biologist Edward Bagnall Poulton.

We are happy to announce that, in celebration of Wallace’s 200th year, we are making the entire Wallace correspondence available to browse online!

Several of the letters in the collection can be connected to the Wallace entomological collections held at OUMNH, providing us with invaluable insights into the history of these specimens. For example, you can read this 1896 letter from Wallace to Poulton in which Wallace discusses the changing of hands of his entomological collections, from Samuel Stevens to Edmond Higgins following Stevens’ retirement in 1867. The Museum subsequently acquired some of Wallace’s entomological specimens through Edmond Higgins, including the two beautiful examples shown above.

Envelope of a letter from A.R. Wallace addressed to Poulton, also available from the OUMNH archive

These letters are a potential treasure trove of information about Wallace and his collections, and we hope they will be of great interest to researchers in the field, as well as to the public. Interested? Learn more about Alfred Russel Wallace or explore his archive online.

The Beginning of the End: Do locusts still spell danger for humanity?

By Ella McKelvey, Web Content and Communications Officer

A few days ago, I was working from home when a delivery driver arrived with a strange parcel – a cardboard box stamped with the letters FRAGILE that seemed to be producing a peculiar, scratching sound. Tentatively, I opened the cardboard box and pulled out a plastic punnet filled with newspaper, old egg cartons, and… wait! Was that an antenna? 

The parcel turned out to be a box of locusts, ordered by my housemate who uses them to feed her pet reptiles. I set the punnet down beside me and tried to continue with my morning’s work. But over the next few hours, the locusts grew increasingly restless, bouncing against the walls of their punnet like hot, microwaved popcorn. The sight and sound of the insects began to return memories of the infamous locust swarms of 2020 — one in a series of near-apocalyptic events that befell us that fateful year. Worryingly, climate change is set to make locust swarms increasingly common, with Sardinia currently facing its worst locust swarm in thirty years.1

Throughout history, locusts have been widely understood as symbols of maleficence and misfortune. One of the oldest written references to locusts is, of course, the Biblical story of the ten plagues of Egypt, in which locusts were sent as a punishment from God. Since then, these infamous insects have been featured in art, books, music, and films as harbingers of destruction. Americans of the mid-twentieth century were somewhat obsessed with giant locusts and grasshoppers which were featured everywhere from cartoons to postcards. 1957 saw the release of the movie The Beginning of the End – a schlocky Hollywood sci-fi tale about a swarm of giant, mutant locusts invading Illinois. The film’s principal Entomologist describes locusts as “deadly killer[s]”, both “intelligent and strong”. Real-life locusts are, indeed, very strong for their size, with back legs that can catapult them up to a metre from standing. This means that it would be feasible for the human-sized locusts in The Beginning of the End to jump as far as forty metres — a terrifying thought!2  

While The Beginning of the End is ridiculous both in premise and execution, I can’t deny that I find the concept of giant locusts pretty nightmarish. Earlier in the week, I sent an email to the Life Collections team to enquire about the possibility of looking through our pinned locusts and snapping a few photos of the biggest and grisliest specimens. As I walked upstairs to entomology, I braced myself for an encounter with some fearsome insects. But what I found were a few drawers of modest-sized locusts that looked about as benign as garden grasshoppers. Many of them were even stuffed with wool; more like teddy bears than agents of Armageddon. 

Left: Anacridium aegyptium or Egyptian Locust from the Collections at OUMNH. Right: Underside of a locust specimen showing cotton wool stuffing.

According to Collections Assistant Rob Douglas, stuffing large insect specimens with cotton wool used to be a common entomological practice. Insects with fatty insides, like locusts, must be gutted to ensure good preservation. Following the removal of the insects’ insides, cotton was often used to return their abdomens to their usual size and shape. Locusts’ ample fat stores contribute as much to their physical prowess as their powerful hind legs; sustaining them through migrations of up to 310 miles a day.3 Such migrations occur when locusts are exposed to a dry spell followed by wet weather, allowing for the sudden regrowth of vegetation. These conditions will cause locusts to switch their solitary lifestyles for gregariousness, coming together to chomp their way through crops and vegetation at a density of 80-160 million insects per square mile. A large migrating swarm of locusts has been estimated to need as many calories in a day as 1.5 million human males, explaining why even ordinary-sized locusts are capable of causing agricultural annihilation.4 

If it weren’t for government and international interventions, the 2020 locust swarms in East Africa could have caused up to $8.5 billion in economic damages by the year-end.5 But locusts can do much worse. One of the most notorious locust swarms on record was that of the Rocky Mountain locust in the USA between 1874 and 1877. According to some accounts, the swarm caused damages to agriculture equivalent to $116 billion in today’s money, leaving behind piles of locust carcases up to six feet high.6 

When it comes to protecting crops from locusts, prevention is better than cure. Likely locust outbreaks can be pre-empted by studying weather patterns and using satellite imagery to keep an eye on vegetation growth.7 Once a (potential) locust swarm has been identified, traditional methods of locust management involve the use of pesticides to wipe out the insects as soon as possible. Back in the 1950s, this meant dowsing locusts with DDT. But as the drawbacks of synthetic pesticides become increasingly apparent, chemical interventions are being replaced with the application of naturally occurring ‘pesticides’ like the fungus Metarhizium acridum.  

Our understanding of locusts has come a long way since the release of The Beginning of the End. One of my favourite news stories of the past month was the announcement by a laboratory at Michigan State University that locusts have been successfully used to ‘sniff out’ mouth cancer.8 It turns out that locusts no longer just spell danger for humanity — they can smell danger for humanity too! These cancer-detecting locusts are, in my opinion, far more ‘sci-fi’ than the giant bugs imagined by scriptwriters of the 1950s, reminding us that, when it comes to science, the truth is often stranger than fiction. Reports like these demonstrate that scientific research has the power to transform our relationship with the pests that have tormented us for thousands of years.

Community science: what’s the value?

ONE SCIENTIST OFFERS HER PERSPECTIVE

By Sotiria Boutsi, Intern

I am PhD student at Harper Adams University with MSc in Conservation Biology, currently doing a professional internship at the Museum of Natural History in the Public Engagement office. My PhD uses genomic data to study speciation in figs and fig wasps.

For most of our history, humans have been observational creatures. Studying the natural world has been an essential tool for survival, a form of entertainment, and has provided the backbone for various legends and myths. Yet modern humans are rapidly losing practice when it comes to environmental observation. As more and more of us relocate to busy urban environments, we find ourselves with little to no time to spend outdoors. Knowledge of the natural world is rapidly becoming the purview of professionals — but it doesn’t have to be this way…

Community science is a term that describes scientific research activities conducted by amateurs, often involving observation or simple computational tasks. Many citizen science projects target schools or families, but everyone is a welcome participant. The purpose of such projects, which run all around the world, is to encourage non-professionals to get involved in science in a fun, voluntary manner, while also collecting data that are valuable for scientific research.

One of the most common forms of community science is biodiversity monitoring. Biodiversity monitoring projects invite people with various levels of expertise to record observations of different species in their local area, and upload evidence like photographs and sound recordings to a user-friendly database. In doing so, they also provide important monitoring data to scientists, like information about the date and location of wildlife sightings.

The Asian Ladybeetle (Harmonia axyridis) was first spotted in the UK in 2004 and since then it has become very common. It is considered one of the most widespread invasive species in the world, with introductions throughout Europe, North and South America, as well as South Africa. Reported observations through the UK Ladybird Survey (Enter ladybird records | iRecord) can help us monitor the spread of this insect and see how other, native species respond to its presence.

There are a variety of mobile apps and online platforms for reporting observations, with some specialising in particular groups of organisms like plants or birds. From the raw data that is uploaded to these platforms, species can be identified through a range of different methods:

  1. Automatic identification from uploaded evidence – often using techniques like image/sound analysis or machine learning
  2. Community feedback – multiple users can view uploaded evidence and make suggestions about which species have been recorded
  3. Direct use of users’ own suggestions – for users who are more experienced with species identification

But are these data actually used by scientists? Although individual contributions to community science projects may seem to be of minor importance, when considered collectively they act as extremely valuable records. Having distribution data for species can help us understand their habitat preferences, and also enable us to monitor invasive organisms. Moreover, long-term data can inform us about species’ responses to changes in their environments, whether that is habitat alteration or climate change. Science is driven by the accumulation of data, and citizen science projects can provide just that.

Biodiversity monitoring through citizen science projects encourage us to notice the tiny beings around us, like this beautifully coloured shiny Green Dock Beetle (Gastrophysa viridula). Moreover, recording common species like the European Honeybee (Apis mellifera) over different years can reveal temporal patterns, like early arrival of spring.

In addition to the benefits to the scientific field, community science projects can also be of huge value to their participants. Firstly, engaging in such activities can help us re-establish our relationship with the wildlife in our immediate environment — we might finally learn to identify common species in our local area, or discover new species that we never realised were so close by. It is surprising how many species we can even find in our own gardens! Moreover, community science events, like biodiversity-monitoring “BioBlitzes”, encourage people from different backgrounds to work together, strengthening local communities and encouraging environmental protection.

Oxford University is currently running the community science project “Oxford Plan Bee“, focusing on solitary bees. The project is creating a network of bee hotels: small boxes with branches and wooden cavities where harmless, solitary bees can rest. The hotels are spread throughout the city, and locals are invited to observe the bee hotels, take photos, and send in their findings.

Overall, community science is as much about being an active participant in the community as it is about doing science. These projects are a celebration of both collective contributions and individual growth. More than anything, they are a chance to pause and notice the little things that keep our planet running.

Want to get involved? Here is a selection of my favourite citizen science projects…

Disappearing Butterflies

HOW TO SOLVE A BIOLOGICAL MYSTERY USING MUSEUM COLLECTIONS AND DNA TECHNOLOGY

By Rebecca Whitla, PhD student at Oxford Brookes University

The Black-veined white butterfly (Aporia crataegi) was a large, charismatic butterfly with distinctive black venation on its wings. Once commonly found in the UK, the species unfortunately went extinct here in around 1925, with the last British specimens collected from Herne Bay in Kent. It isn’t fully understood why the species disappeared from the UK, but climate change, predation, parasites, and disease have all been suggested to have caused its disappearance — perhaps with several of these factors contributing to its decline. Central to solving the mystery of the disappearance of the Black-veined white will be the collections of butterflies that are stored in museums like OUMNH.

Butterflies tend to be well-represented in museum collections, and the Black-veined white is no exception. While the species has now been extinct in the UK for around 100 years, Lepidoptera enthusiasts from previous centuries often captured wild Black-veined white specimens for their personal collections. The abundance of Black-veined white butterflies in museum collections, like the collections at OUMNH, serve as a valuable repository for scientific research — including my own!

Black-veined white butterflies in the collections at OUMNH

Between June and December 2021, I undertook a research project using OUMNH’s Black-veined white butterflies. My task was to extract enough DNA from the butterflies to use for ‘whole genome sequencing’ — in other words, I was attempting to extract DNA from butterfly specimens to decode their complete DNA sequence. Getting DNA sequences from the historical specimens that are kept in Museums is no easy task, as DNA degrades over time. Nonetheless, animal specimens from natural history museums have successfully been used for whole genome sequencing and genetic analysis in the past, including species as diverse as longhorn beetles and least Weasels.

In order to work out how to extract DNA from the specimens, I had to try a variety of methods. This included experimenting to find out whether butterfly legs or abdomen fragments yielded more DNA, and whether non-destructive methods of DNA extraction were as effective as destructive methods. An example of a non-destructive method of DNA extraction would be a process like soaking a sample overnight and using the leftover liquid for DNA extraction, whereas a destructive method might involve mashing a whole leg or abdomen segment to use as a DNA source.

Preparing a DNA sample

Overall, I found that destructively sampling the legs of the butterflies gave the most reliable results, and also had the added benefit of not destroying the wings or abdomen of the specimens. Keeping the wings and abdomens of the butterflies intact will likely prove useful for conducting morphological studies in future.

Now that I have a reliable DNA extraction method, the next step in my research will be to analyse more Black-veined white specimens from a span of different time periods leading up to the species’ disappearance. I will then compare samples collected from each time period to calculate the genetic diversity of the species at each point in time, leading up to its disappearance. If I find a steady decline in the species’ genetic diversity over time, this may indicate a gradual extinction of the species. This is because we expect that, as numbers of a species decrease, inbreeding will become common, resulting in less diversity in the species’ DNA. However, if the populations of Black-veined white butterflies went extinct very suddenly, the decline in genetic diversity will probably be less pronounced. Learning more about the fate of the Black-veined White could not only help us unlock the historical mystery of the species’ decline in Britain, but will also help us understand more about the species’ decline in other parts of the world.

British Insect Collections: HOPE for the Future is an ambitious project to protect and share the Museum of Natural History’s unique and irreplaceable British insect collection. Containing over one million specimens – including dozens of iconic species now considered extinct in the UK – it offers us an extraordinary window into the natural world and the ways it has changed over the last 200 years. The HOPE for the Future project is funded by the National Lottery Heritage Fund, thanks to National Lottery players.
