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.

NatSCA Digital Digest – February

Compiled by Glenn Roadley, NatSCA Committee Member, Curator of Natural Science at The Potteries Museum & Art Gallery.

Welcome to the February 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 museum re-openings, exhibition launches, virtual conferences, webinars, and new and interesting online content. If you have any top tips and recommendations for our next Digest please drop an email to blog@natsca.org.

Where to Visit

There are plenty of things to see and do online this February. Throughout 2021, the Science Museum is running a series of Climate Talks, with three taking place this month on the 13th, 15th and 12st and previous talks available to watch via the Science Museum website.

National Museum Cardiff is hosting an online Dino Nights sleep-over event for children, including fort-building and a torch-lit tour with a dinosaur expert.

For those wanting to use the time at home to brush up on some natural history ID skills, the Tanyptera Trust are continuing their series of webinars, with events in February focussing on nocturnal ichneumonoid wasps and centipedes.

And just missing February, but pre-dating our next Digest, the Museums Association will be hosting a Climate Crisis event for members on March 3rd, part of their Coronavirus Conversations series.

The last of our NatSCA blogs covering the NatSCA Decolonisation Conference have now been published, completing the series. The whole conference is now available to watch any time for free via YouTube, so be sure to catch up with these powerful talks if you’ve not yet had the chance.

Register now for this ONLINE DAY MEETING 10.00–14.00 FRIDAY, 12 MARCH 2021.
This meeting will bring together researchers from different disciplines (natural sciences, evolutionary biology, philosophy, history of science and gender studies) to discuss ‘race’ and ‘sex’ in Linnaeus’ work and beyond.
This event will take place online using Zoom webinar.
  • Ticket price is £5 for Fellows, Associates and Student Members / £10 for the general admission
  • Registration is essential, and will close 24 hours before the event is set to begin

Chill Out: A Cautionary Note On The Use Of Aqueous Treatments On Taxidermy

Written by Lu Allington-Jones, Senior Conservator at the Natural History Museum, London.

Whilst trying (not very successfully) to find a “cure” for fat burn (Figure 1), I made an unwelcome discovery: sometimes the shrinkage temperature of deteriorated skin is actually lower than room temperature. This means that the skin will irreversibly shrink as soon as any water-based treatments are applied.

Figure 1. Fat burn can cause skin to rip and specimens fall apart

Shrinkage temperature (Ts) is commonly used in leather conservation to determine the level of deterioration, and the effectiveness of treatments. Ts is the temperature at which 2 corian fibres immersed in water show simultaneous and continuous shrinkage activity. It shows the level of deterioration because it indicates destabilisation of collagen fibres. Ts of fresh skin is 65oC and in deteriorated leather this can be reduced to 30oC (Florian, 2006). Ts is measured by immersing samples of leather (or skin) in water and gradually increasing temperature until shrinkage activity is observed under a microscope (Larsen et al. 1996; Vest & Larsen, 1999).

Legacies Of Jamaica: A Not So Elegant Priest!

Presented by Mama D Ujuaje & Rhian Rowson, Bristol Museums, Galleries & Archives.

Abstract

This presentation discusses a previous successfully curated public event, The Food Journey, held in the summer of 2019, forming part of a long term international project linked to our Jamaican botanical collection.

Addressing many of the contentions of Jamaican history, this presentation evokes a feel of mid-eighteenth century Jamaica by describing how making use of dramatic narrative, a soundscape, food tasting, aromas and textures of the time and geography, allow the context of the collection to come alive and to, as it were, ‘answer back’ to the authority of the author’s claims. We use costumed dialogue to help re-enact the immersive feel of the original production.

We include in our presentation a discussion of how the collection came about and its use over the years and how that might be critiqued in the context of slavery analyses over time and current notions concerning the erasure of traditional knowledge forms.
