Stepping Into The Genomics Age: A DNA Bank at World Museum, National Museums Liverpool.

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

From World Museum’s founding collection of study skins and taxidermy mounts bequeathed by the 13th Earl of Derby to the spirit-preserved amphibians collected by curator Malcolm Largen in the 1980s, World Museum’s Vertebrate Zoology collection has continued to expand and reflect the state-of-the-art in specimen preparation and storage.

As ethics around the sacrifice of animals for science have modernised, ‘traditional’ specimen types are no longer being prepared at the same rates, and growth of the collection has slowed abruptly. At the same time usage of the collection has diversified, including increases in requests for destructive sampling. In particular, the removal of small tissue samples, usually bird toe pad scrapes, is regularly requested for use in DNA extraction which produces a ‘pure’ DNA extract that can be used in a number of genomic investigations.

Extinct – A New Exhibition At The Manx Museum

Written by Laura McCoy, Curator of Natural History for Manx National Heritage.

Wednesday the 8th September saw the opening of the new temporary exhibition ‘Extinct’ at the Manx Museum on the Isle of Man, in partnership with Manx Wildlife Trust, which also coincided with the launch of the Red Data bird list published by Manx BirdLife. There are many species that have become locally extinct on the Isle of Man, particularly birds and plants, and this trend is not slowing down, with the Yellowhammer, once one of our most ubiquitous farmland birds, disappearing from our Island only in 2019. Some may ask how these absences impact our day-to-day lives, why this matters, but as we are becoming increasingly aware, the complexity and variety of our environment is what sustains us; if you knock out enough of the bricks the wall will come tumbling down. These disappearances are symptomatic of a grave state of affairs and islands are particularly sensitive to changes in management and climate. The more protected and supported our environment is, the better it is able to withstand and buffer us from the global shifts that are to come.

When Manx Wildlife Trust came to Manx National Heritage with the idea of this exhibition we were fully on board; learning about these stories of the Isle of Man’s countryside has been a journey, sometimes an upsetting one, but it has also been a call to arms. I had no idea that currently 29% of our current resident bird species, never mind the ones that are already gone, are red listed, and 41% are amber. An estimated forty five species of plant are extinct, seventy seven are red listed. We are still trying to compile what invertebrates and fungi we have, never mind assess what has been lost.

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.

NatSCA Digital Digest – July

Compiled by Lily Nadine Wilkes, NatSCA Volunteer.

Welcome to the July edition of NatSCA Digital Digest.

A monthly blog series featuring the latest on where to go, what to see and do in the natural history sector including jobs, exhibitions, conferences and training opportunities. We are really keen to hear more about exhibition launches, conferences (live or virtual) and webinars, and new or interesting online content. If you have any top tips and recommendations for our next Digest please drop an email to blog@natsca.org.

What To See & Do

The ‘Insectarium: Fascination and Fear’ exhibition present artwork on the feelings that insects inspire in us. If you can’t make it to Aberlady, Scotland, you can view the art online here.

If you’re looking for something crafty to do there are plenty of online workshops to take part in. With the Oxford University Museum of Natural History on 14th July at 8pm participate and enjoy ‘Drawn to Nature: Conservation’. In this online event you will hear about the art of conservation before taking a chance to draw some natural history specimens. The Natural History Museum are offering making sessions where you can create a crochet dinosaur or make your own plant pot.

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.
