Size Matters: Pesticides in Large Mounted Vertebrate Specimens

Written by Becky Desjardins (Senior Museum Preparator & Conservator), Georgia Kay & Kim König (MSc students Museums & Collections – Leiden University; Naturalis Interns), Naturalis Biodiversity Center.

Back in 2013, Naturalis conducted a research project about arsenic in the museums’ specimens. The goal was to determine if arsenic was spreading from the collection areas into staff and or public areas of the museum. We tested many specimens with an XRF but also tested the elevators, door handles, floors, shelves, keyboards, etc. From this testing we developed protocols about handling specimens and how we use the spaces in the collection. You can read all about that project over here.

What didn’t get tested were the large mounted vertebrates. Back in 2013 the Naturalis collections were spread over a number of warehouses around Leiden. Because these external buildings were considered depots only (meaning no offices/canteens in these spaces) there was less concern about arsenic contamination in non-collection areas. The large vertebrates were considered to be high risk specimens (so very toxic), and were handled as such, they never had their moment with the XRF.

Behind The Heads: Natural History, Empire and The Abel Chapman Collection. Part 2.

Written by Dan Gordon, Keeper of Biology, The Great North Museum: Hancock.

Abel Chapman’s time in southern Africa was only the first of many visits to the continent. His next trip, in 1904, was to a very different place – British East Africa. This was a colonial protectorate roughly equivalent to today’s Republic of Kenya. It had grown out of land leased by the British East Africa Company but was now firmly under British imperial control.

The Uganda railway, a huge feat of engineering, had been completed just three years before Chapman’s visit. This now allowed trains to travel the 800km (500 miles) between Mombasa on the east coast and the African Great Lakes. The British now had the means to extend their influence right across East Africa, disrupting the slave routes and simultaneously opening up the land to the missionaries, settlers, tourists and game hunters that were now pouring in. It was in this rapidly changing environment that Chapman strove to find the longed for wilderness that had eluded him in Transvaal, and test his skills as a sportsman, before that land too vanished under the settler’s plough.

Behind The Heads: Natural History, Empire and The Abel Chapman Collection. Part 1.

Written by Dan Gordon, Keeper of Biology, The Great North Museum: Hancock.

In the museum’s basement is a room filled with heads. Row after row of them stare out from metal racks, glassy eyed and bristling with every kind of horn and antler. Visitors to this room are sometimes awestruck at the breadth of species on display. The Kudu, its head crowned by spiralling horns like giant corkscrews. A tiny Klipspringer with horns like shiny black thorns. The huge Eland, its vast head armed with massive horns like tank shells. A parliament of Africa’s fantastic beasts, all in this small storeroom. These are hunting trophies from the Abel Chapman collection. When he died in 1929 they were taken down from the walls of his Northumberland home, and gifted to the museum.

In light of the current conversation about museums and colonialism, and the insightful work of Lowe and Das on the subject of Natural History collections in this context, I thought I’d try to learn more about the history of the great North Museum’s African collections, and my attention was caught on the horns of Chapman’s trophies. The more I’ve learned about their story, the more I’ve come to feel that trophy heads, some of the most recognisable Natural History objects, are great examples of the way that colonialism has both helped to shape naturalism, museum collections and even our ideas about wildlife conservation.

The story of our collection begins in 1851 when Abel Chapman was born into a wealthy Sunderland brewing family. Educated at the elite Rugby School, he joined the family firm as a young man and embarked on a successful business career. Chapman was intelligent and adventurous, making expeditions to places like Canada, Scandinavia and the Arctic. In detailed notebooks filled with deft pencil sketches he documented the things he heard, saw and shot, and used these to write a whole series of books. He built a reputation as a ‘hunter naturalist’ passionate about combining field sports with game preservation, and as well as amassing a horde of trophies, he became an influential figure in the emerging field of wildlife conservation.

We Brought Our Electric Ray Specimens Into The Lab…What Happened Next Will Shock You!

Written by Claire Smith, Project Officer at the Cole Museum of Zoology.

If you’ve been following the Cole Museum of Zoology on Twitter, you’ll know that the museum is closed at the moment – not only because of the COVID-19 lockdown, but also because we’re preparing our collections for their move into a brand new Life Sciences building. While the new museum may not be ready to open until 2021, we have plenty of work to do behind the scenes in the meantime.

Along with a team of staff and volunteers, I work on the fluid-preserved collections at the Cole Museum. As well as the ongoing task of keeping all of the wet specimens in good condition, we’re also putting some into safe storage, and getting others ready to go out on display. As part of my fluid-preservation Twitter, I share weekly threads about the kinds of tasks that the team takes on.

When specimens come into the lab needing work, we identify them from an abridged version of the museum’s catalogue. This gives us basic information such as the specimen’s accession number, its species, and what kind of fluid it’s preserved in. The majority of the Cole Museum’s specimens are fairly new, by museum standards – they’re mostly around 60 to 100 years old. Many of them have been re-sealed, re-mounted or been housed in new jars during this time, but every now and then we come across one which appears untouched. Continue reading →

Time To Figure Out Where Specimens Are Really From

By John-James Wilson, Curator of Vertebrate Zoology, World Museum, National Museums Liverpool.

In 2020 the Vertebrate Zoology collection at World Museum took a step towards ‘FAIR’ data sharing and began adding datasets of specimen records to the Global Biodiversity Information Facility (GBIF). There is always a trade-off between releasing datasets as soon as possible and ensuring they contain the most precise and reliable data possible. We’ve taken the view that through releasing these datasets, and encouraging their use, a positive feedback loop will incrementally improve data quality. That said, due to restrictions on other activities, one side effect of the Covid pandemic has been a little more time for in-house provenance research.

One collection I’ve focussed on during this time is that of prolific collecting duo, Herbert Christopher Robinson and Cecil Boden Kloss, which came to World Museum from the Federated Malay States Museums (FMSM) in 1914. Robinson, a former assistant at the Liverpool Museums, directed the FMSM from 1908 until 1926; Boden Kloss was the colleague ‘to whom he was much attached’. It seems that the FMSM specimens arrived in Liverpool without any additional documentation, so the collection locality information in our database (at National Museums Liverpool we use Mimsy XG) must have originally been transcribed from specimen labels with ‘place collected’ presumed to be Malaysia.
