A Day in the Life of a Natural History Curator

My name is Jennifer Gallichan and I am one of the natural history curators at National Museum Cardiff. I care for the Mollusc (i.e. snails, slugs, mussels, and octopus) and Vertebrate (things with backbones) collections. Just like everybody else, museum curators are adapting to working from home. But what did we use to do on a 'normal' day, before the days of lockdown?

Caring for the National Collections

Most of our specimens are not on display. Amgueddfa Cymru holds 3.5 million natural history specimens and the majority are held behind the scenes in stores. Caring for the collections is an important part of our role as curators. We have to meticulously catalogue the specimens to ensure that all of the specimens are accounted for. As you can imagine, finding one object amongst 3.5 million could take a while.

Natural history collections cover a whole range of materials including shells, dried plants, minerals, fossils, stuffed animals, bones, pinned insects and fluid preserved specimens (this includes things in jars).

These collections are vital for research, education, exhibitions and display. Some have been in the museum for well over a century, and it is our role to ensure they last into the next century and beyond. We work with specially trained Conservators to monitor the collections and highlight anything that might be at risk, needs cleaning or repair.

Answering your Questions

We spend a lot of time working with you, our fantastic visitors. Much of our time is spent answering the thousands of enquiries we receive every year from families, school children, amateur scientists, academics of all kinds, journalists and many more. We also host open days and national events throughout the year which are another great opportunity to share the collections. Many of us are STEM (Science, Technology Engineering & Mathematics) ambassadors, so an important part of our role inspiring and engaging the next generation of scientists.

Working with Volunteers

Our museums are crammed full of fascinating objects and interesting projects to inspire and enjoy. We spend a lot of time with our excellent volunteers, helping them to catalogue and conserve the collections, guiding them through the often intricate and tricky jobs that it has taken us decades to perfect.

Working with Other Museums

Museums across the world are connected by a huge network of curators. We oversee loans of specimens to all parts of the globe so that we can share and learn from each other’s collections. We have to be ready to deal with all manner of tricky scenarios such as organising safe transport of a scientifically valuable shell, or packing up and transporting a full sized Bison for exhibition.

Working with Visitors

Despite the fact that a large part of the collections are behind the scenes, they are open to visitors. Researchers from across the globe come to access our fantastic collections to help with their studies. We also host tours of the collections on request.

Making Collections Bigger and Better

Despite having millions of specimens, museum collections are not static and continue to grow every year. Be it an old egg collection found in an attic, or a prize sawfish bill that has been in the family for generations, it’s an important part of a curator’s job to inspect and assess each and every object that we are offered. Is it a scientifically important collection or rare? Has it been collected legally? Do we know where and when it was collected? Is it in a good condition? Do we have the space?

Creating New Exhibitions

A fun part of the job is working with our brilliant Exhibitions department to develop and install new exhibitions. We want museums to be exciting and inspiring places for everyone so we spend a lot of time making sure that the information and specimens we exhibit are fun, engaging, inspiring and thought provoking.

Being Scientists

Last but definitely not least, when we aren’t doing all of the above, we are doing actual science. Museums are places of learning for visitors and staff alike. Many of us are experts in our field and undertake internationally-recognised research. This research might find us observing or collecting specimens out in the field, sorting and identifying back in the lab, describing new species or researching the millions of specimens already in the collections.

Museums from Home?

Despite lockdown, we are working hard to keep the collections accessible. We’re answering queries, engaging with people online, writing research papers and chipping away at collection jobs from home. And like all of you, we are very much looking forward to when the museum opens its doors once again.

If you want to find out more about the things we get up to in the museum, why not check us out on Twitter or follow our blog? You can also find out more about all of the members of the Natural Sciences department here.

Augusta Hall, Lady Llanover (21 March 1802 – 17 January 1896) was a strong advocate and supporter of the Welsh Woollen Industry and Welsh traditions. At the National Eisteddfod in 1834 she submitted an essay titled `The Advantages Resulting from the Preservation of the Welsh Language and the National Costume winning first prize. She took the bardic name "Gwenynen Gwent" 'the bee of Gwent'.

Harpist's Costume from the Llanover Estate

In 1865 she commissioned the building of Gwenffrwd Woollen Mill on the Llanover estate near Abergavenny. The mill carried out all operations for woollen production and produced heavy flannel cloth that was made into clothes for the house and estate workers to wear.

Material from the mill was also made into clothes for lady Llanover and her friends styled on her own ideas of Welsh traditional Costume. The mill continued in production until the 1950s using equipment installed by Lady Llanover.

Most gardeners regard horsetails or scouring rushes (Equisetum) as one of their worst enemies – once this invasive weed is in your garden or allotment, it will spread everywhere and is almost impossible to get rid of (Fig. 1). But of course from the plant’s perspective this is a success story – they are doing what is best for them, not for us!

Today, this genus of highly invasive plants consists of only 15 species (Fig. 2), but they are found throughout the world except in Antarctica. They also have an immensely long evolutionary history spanning over 350 million years.

Fossils of horsetails are commonly found in the Carboniferous age coalfields such as in South Wales. The star-shaped leaf whorls (Annularia) are among the iconic fossils found in these rocks. We now know they were parts of tree-sized plants up to 10 metres or more tall – I have often wondered what today’s gardeners would think if they encountered a living one of these giants!

A couple of years ago, my colleague Pedro Correia sent me a photograph of a fossil Annularia that he had found in Portugal (Fig. 3). In itself, this wouldn’t have been too unusual, but this one had a strange structure attached among the leaves. It almost looked as though it was a seed but of course that was impossible – horsetails do not have seeds, but reproduce by spores, in the same way as ferns. We shared this photograph with other European colleagues and a debate ensued as to what on Earth this could be. For a time it remained a puzzle. But then we showed it to another colleague, Conrad Labandeira from the Smithsonian Institution (Washington DC), who is one of the world’s leading palaeontological experts on insect – plant interactions. He suggested that this was probably a structure known as a gall.  Most galls today are produced when an insect injects chemicals into the plant to produce a swelling, in which it lays an egg. The resulting larva then develops within the gall.

There is evidence of Annularia leaves having been eaten by insects, such a chew-marks around the leaf edge. Conrad had also published evidence some years ago of an insect gall in a Carboniferous tree fern stem. But a gall on a Carboniferous horsetail is most unusual.  For a time we thought this example might be unique. But we then found a paper published back in 1931 by the American palaeobotanist Maxim Elias, who claimed to have found a seed attached to an Annularia. But it is now clear that Elias hadn’t in fact discovered a seed-bearing Annularia, as he had thought, but an insect gall similar to ours.

Fossil galls of this age are extremely rare. What insect produced this one is unknown. The organism was not preserved and most of today’s gall-producing insect groups do not have a fossil record extending this far back in time. All that we can say is that it was probably caused by a member of a now-extinct insect group that presumably produced larvae as part of its life cycle (Fig. 4).

Most horsetails have thick, almost leathery stems and I still find it rather strange that insects produce galls on them. But they do today on at least some horsetails, and it has clearly been of benefit to insects for millions of years. We haven’t yet found one in the Welsh coalfields but, now we know what to look out for, we will be keeping our eyes open!

In my previous blog I explained what rafting bivalve shells are and how Caribbean bivalves are ending up on British and Irish shores attached to plastics. There are numerous records of non-native bivalves on plastics in the southwest of Ireland and England but nothing has yet been reported in Wales, which is something that I’m trying to rectify. To encourage recording I’m enlisting citizen scientists – volunteers from the general public – who can help to spot and identify these rafting species in Wales. But first of all, I want to check to see if there are rafting species turning up on our shores so I began talking to groups who already go out on the shores to survey, beach clean or educate.

In December 2019 I met with a fantastic group of people at PLANED in Narbeth. PLANED have excellent coastal community links and everyone I spoke to was enthusiastic and willing to incorporate the rafting bivalves project into their usual activities of beach cleans, foraging, outdoor activities or education.  They were keen to help record any rafting species that they discover and we talked about how to identify any bivalves found. Since then I have been working on an identification guide that I plan to develop with the help of these community groups.

 

Pembrokeshire National Parks staff and volunteers looking for plastics at Freshwater West beach

In February 2020 I met up with 35 people at the Pembrokeshire Coast National Parks offices in Pembroke Dock. They were eager to learn more about non-native bivalves on plastics. After lunch, those daring enough braved the freezing temperatures and gales to carry out a mini beach clean at Freshwater West beach. We found a lot of large plastic items in less than half an hour which we brought back to the car park for a closer look. Even though there were a lot of pelagic goose barnacles (stalked crustaceans related to crabs and lobsters that attach to flotsam) on some items, proving that the items had been floating in the ocean for a long time, no non-native bivalves were found.

conference where I presented the project and had several more offers of eyes on the ground to record and test the identification guide, which is great news.  I’ve also set up a Facebook page where volunteers can post images of any suspected non-native bivalves for me to identify. I’m hoping to meet up with several more groups later in the year to ask them to look for these pesky hitchikers so we can find out if and where they are attempting a Welsh invasion!

The National Wool Museum in Drefach Felindre is home to a comprehensive collection of tools and machinery involved throughout history in the processing of woollen fleece into cloth. It also holds the national flat textile collection and the best collection of Welsh Woollen blankets with documented providence dating back to the 1850s. These range from large double cloth tapestry blankets that are now very collectable, to plain white single utility blankets from WWII. In this blog, Mark Lucas, Curator of the Woollen Industry Collection for Amgueddfa Cymru – National Museum Wales, shares his knowledge of the heritage of Welsh blankets and some fine examples from this important collection.

 

Welsh Blankets traditionally formed part of the bottom draw for Welsh brides. A pair of Welsh blankets was also commonly given as a wedding gift. The would have travelled great distances with people moving during the Industrial Revolution looking for work, but wanting to keep a small piece of home with them. Thus, Welsh blankets have found their way across the world, adding a touch of homely aesthetic to a room by day and providing warmth at night.

 

Narrow Width Blankets

Narrow Width Blanket - two narrow lengths stitched together.

Narrow width blankets were the earliest, woven on a single loom. They were made of two narrow widths hand sewn together to form a larger blanket. Single loom blankets of this type were the norm before the turn of the twentieth century when the introduction of the double loom enabled the weaving of broader widths of fabric. However, many of the smaller mills, as well as individual weavers, did not convert to wider looms and, as a result, narrow-loom blankets continued to be produced in significant quantities during the 1920s, 30s and even later.

 

Plaid Blankets

Plaid Blanket

Plaids were popular during the nineteenth century, usually featuring strong colours against a natural cream background. The introduction of synthetic dyes in the late 19^th century allowed weavers to mix more coloured yarns into the designs, although some colour combinations were subtle, others could be gaudy. Many smaller mills continued the use of natural dyes well into the 20^th century. The natural dyes were made from madder and cochineal for reds, woad and indigo for blues, and various berries and lichens for other shades. The National Wool Museum has its own natural dye garden and hosts courses and talks throughout the year on natural dyeing

 

Tapestry Blankets

Tapestry Blanket

Welsh Tapestry is the term applied to double cloth woven blankets, producing a pattern on both sides that is reversible and is the icon of the Welsh woollen industry. Examples of Welsh tapestry blankets survive from the eighteenth century and a pattern book from 1775 by William Jones of Holt in Denbighshire, shows many different examples of tapestry patterns. Double cloth was first used to make blankets, but its success as a product for sale to tourists in the 1960s led to its use as clothing, placemats, coasters, bookmarkers, tea cozies, purses, handbags and spectacle cases. Because of the hardwearing quality of the double cloth weave the material has also been used for reversible rugs and carpeting.

 

Honeycomb blankets

Honeycomb Blanket

Honeycomb blankets are a mixture of bright and soft colours. As the name implies the surface is woven to produce deep square waffle effect giving the blanket a honeycomb appearance. This type of weave produces a blanket that is warm and light.

With the current resurgence of Welsh blankets for a decorative home-style item there is much interest in old blankets and the designs patterns. Antique blankets have become very popular with interior designers and feature heavily in home décor magazines. They are used as throws and bed coverings in modern homes with many high-end textile designers as well as students researching old patterns for inspiration for their new designs.

Caernarfon Blanket

Many of the fine examples in the Museums’ blanket collection come from mills across Wales that ceased production long ago. A highlight is the collection of Caernarfon Blankets. These were produced on Jacquard looms in a range of colourways. Only a few mills used Jacquard looms, which can make complicated designs and pictures. The Caernarfon blankets show two pictures one with Caernarfon Castle with the words CYMRU FU (Wales was) and a picture of Aberystwyth University with the words CYMRU FYDD (Wales Will Be). It is believed that these blankets were first been made in the 1860s, and last produced for the investiture of Prince Charles in 1969. A recent donation to the museum is an earlier example of the blanket featuring two images of Caernarfon castle. Woven by hand it contains a critical spelling error - Anglicising the name to Carnarvon.
