Jazmine with the River Otter Beaver in process

In April 2019 Holly Morgenroth (Collections Officer at The Royal Albert Memorial Museum) gave me a call to say she had acquired a dead beaver that was in good condition for taxidermy. This was significant because this beaver was part of the River Otter Beaver Trial. All deceased beavers should now be sent to the Zoological Society of London for medical autopsies, which means they are usually not in good enough condition for taxidermy after the procedure. This particular beaver, originally from a population of beavers in Scotland, had been introduced to the River Otter in April 2019 to expand the gene pool of the population. Sadly she was found dead – it is possible she drowned in salt water as there were no visible injuries from conflict or a road traffic accident. Devon Wildlife Trust decided she did not need a post mortem and very kindly handed her over to Holly at the museum. Holly jumped at the opportunity and expertly packed her into a large plastic tub and placed her in the museum’s chest freezer and got to work obtaining funding to have her processed into taxidermy and a full skeleton.

A Very Important Beaver

Written by Holly Morgenroth, Collections Officer / Natural Sciences Curator, RAMM.

A New Acquisition for RAMM

This blog post tells the story of a new and very important acquisition for the Royal Albert Memorial Museum & Art Gallery (RAMM) in Exeter. I grew up in a small Devon village called Otterton and spent many happy hours wandering the banks of the River Otter observing the rich wildlife it had to offer. So when in 2013 news broke that a family of beavers (a species extinct in the wild in Britain for over 400 years) had made the river their home I watched with great interest.

Their arrival divided opinions. The Government planned to remove them from the river. But the beavers captured the hearts of the public and Devon Wildlife Trust (DWT) saw a unique opportunity for research. The beavers became part of a five year scientific trial run by DWT to assess their impact on local geography, ecology and people. The results of the trial were overwhelmingly positive.

NatSCA Digital Digest – October

Compiled by Lily Nadine Wilkes, NatSCA Volunteer.

Welcome to the October 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 and 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.

Note from editor: Unfortunately this is the last of Lily’s posts as she had stepped down from her role as part of the Digest team. A huge thanks for all your contributions! If anyone is interested in taking up her position, drop me a line.

What to Do

There are lots of fun Natural Science activities happening in October half term, like the Marine Day at the Great North Museum: Hancock. The National Museum of Scotland has lots of activities to do in October Half Term. This event at National Museums NI Ulster Folk Museum on the Naturalists Notebook looks fascinating.

Databasing Herbarium Specimens and Ease of Use.

One of the main aims of creating online databases of herbarium images (or any data set) is to increase the ease of access for researchers, educators, and other users who may want to obtain data from the specimens without having to physically travel to an herbarium. Online herbarium databases have become particularly useful during the global COVID-19 pandemic, when many herbaria are not allowing or greatly reducing the amount of in-person visitation.

For many herbaria, online databases are still being constructed and ease of access and use can vary significantly between collections. Additionally, while a database may list a certain number of specimens held by the herbarium, it can often be the case that only a subset of these specimens are actually imaged and available to view online. Some herbarium databases are better than others in actually allowing the user to narrow down their search to get the data they are looking for. The databases range in ease of use from ‘very easy’ to ‘usable but frustrating’. Any databases that are too difficult to use often dissuade researchers from using the digital resources available on that database.

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.
