Diminished Scales – The Plight of The Pangolin and The Role of Museums

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

To explain grace requires a curious hand’ wrote Marianne Moore, in her 1938 poem, The Pangolin. Moore first learned about pangolins at college in biology class and remained fascinated by them for the rest of her life. Curiosity was what first drew me to pangolins, too. Not just about their curious, clawed hands – when I first encountered a stuffed pangolin at the Great North Museum, its whole appearance was like nothing I’d ever seen. A small quadruped, clad in precisely overlapping rows of jagged scales, like steel plating welded onto a badger. A huge tail at one end, a tapering snout at the other. It was an animal that suggested a host of comparisons – a pinecone, an artichoke, a dinosaur. What on earth was it? I decided to investigate.

I soon learned it was a Ground Pangolin (Smutsia temnickii), one of eight species of pangolin that make up the family Manidae. Pangolins are the only scaled mammals and are found in tropical Africa and Asia. Most species live nocturnal, solitary lives. They’re notable for all sorts of reasons. The Ground Pangolin can walk on its back legs, like a tiny T-rex in a suit of armour. The Black-bellied Pangolin has a tail so long it has more bones than any other mammal.

Our Top Ten Blogs of 2019

Written by Jennifer Gallichan, Curator of Molluscs & Vertebrates at National Museum Cardiff.

2019 was an interesting year for me as I took on the role of NatSCA blog editor. It has been a great year and I have very much enjoyed reading all of the articles from our amazing contributors. To celebrate this, I wanted to bring together a list of our top ten most viewed blogs from 2019 in case you missed any of them.

Top scorers this year include a surprising number of botanical articles, with four of the ten written by our plant loving colleagues.

Some of my personal favourites, although not top scorers, are actually two articles which we were kindly allowed to re-blog: Annette Townsend’s beautiful and mesmerising work in how to make a wild strawberry sculpture from honey bee wax, and John Wilson’s fantastic article about the orang-utan specimens sent to World Museum, Liverpool by Alfred Russell Wallace.

But, here are the top ten most read NatSCA blogs by your good selves…

Survey of Flowering Plants Stored in Fluid Preservatives Across European Herbaria

Written by Ranee Prakash, Senior Curator (Flowering Plants), Algae, Fungi and Plants Division, Department of Life Sciences, Natural History Museum, London.

A survey of flowering plant material stored in various fluid preservatives across several European herbaria/institutions was carried out a few years ago. The feedback received from the survey is shared and shows that the majority of the herbaria use 70% IMS (industrial methylated spirit) to store their collections.

Introduction

The seed plant collections (stored in various liquids such as formalin, some have unknown liquids, and some mention poison) form a relatively small yet significant part of the botanical holdings at NHM (Natural History Museum). They include some important material dating back to the mid 1800’s and type collections such as the world’s largest flower Rafflesia arnoldii collected by Robert Brown. However, these wet collections have remained a somewhat underused asset and are in dire need of curatorial attention.

In continuation to this aim, a survey of flowering plants stored in spirit collections across various institutions in Europe was carried out in 2012 so as to assess what preservatives other institutions were using and what would be the best method to store the collections at NHM for posterity. The objective of this survey was to gather information on:

  • How big the spirit collection is
  • How the collection is used
  • Which liquid preservatives the flowering plant collections are stored in

The Missing Lynx: The Past and Future of Britain’s Lost Mammals

Written by Jack Ashby, Manager of the University Museum of Zoology, Cambridge, and author of Animal Kingdom: A Natural History in 100 Objects.

A good title goes a long way, and based on that alone I was excited to receive a review copy of Ross Barnett’s new book through the post. I knew of Ross from Twitter – and I can heartily recommend following him for a whole host of natural history-related wonders, particularly around climate change, ancient mammal DNA and palaeontology. As a result, I was slightly surprised that he had written a book that I assumed – from the clever title – was about reintroducing the lynx to Britain.

That is, in fact, not what the book is about. Instead, it takes us species-by-species, chapter-by-chapter, through the incredible range of beasts that have disappeared from the British Isles in recent millennia (I should have paid more attention to the subtitle). We learn about the woolly mammoths and rhinos, the huge cave bears and their slightly smaller relatives, cave lions and cave hyenas, sabretooth cats, massive species of cattle and deer, as well as wolves, beavers and, yes, lynx. All of these stories are told in the voice of a person clearly fascinated and excited by the things he has been studying all his life, and with a dry sense of humour.

Invertebrates In Vitro

Written by Paolo Viscardi, Curator of Zoology, National Museum of Ireland – Natural History

I’m not sure why, but people really seem to love Blaschka models.

They are the subject of a surprisingly large number of enquiries at the National Museum of Ireland — Natural History (AKA the Dead Zoo), where I look after the zoology collections.

If you’ve not heard of the Blaschkas, they were a father and son company of lampworkers based in Dresden, who supplied museums and universities around the world with glass models for teaching and display. Between 1864 and 1890 they made mail-order models of invertebrates (alongside glass eyes and medical equipment), then from 1890 until 1936 they worked exclusively for Harvard University on the Ware collection of glass flowers.

At the Dead Zoo we have a particularly large and comprehensive collection of the invertebrates, with around 590 models acquired in lots between 1874 and 1888. I say ‘around’, because many of the models are made up of multiple parts, with different developmental stages, enlargements and details that are classed as elements of the same model.

Brendel Plant Model Survey

Written by Donna Young, Curator of Herbarium, World Museum, National Museums Liverpool

Inspired by the project led by the Corning Museum of Glass, which looked at holdings of Blaschka models, I am embarking on a project to map and document collections of Brendel botanical models worldwide.

The objective of this project is not only to provide a useful resource to be used in the curation of anatomical models, but to document their past and present use – promoting and bringing awareness of these collections to new audiences.

Anatomical Models

The nineteenth century was the golden age of scientific discovery, and as the century progressed, the teaching of science in schools, academies and museums evolved to reach a new mass public audience. Science was no longer the exclusive preserve of an elite few.

Changing teaching techniques promoted this transformation and pedagogical inquiry was seen as a constructive and involved way of learning. The written and spoken word was supported by the use of visually instructive wall charts and classroom demonstrations. The introduction of interactive teaching models encouraged audiences to understand nature using new and original perspectives.

Botanical models were used to illustrate and demonstrate plant anatomy. Unlike living material, their use was not restricted by seasonal availability and they were ideal for demonstrating small or ephemeral details which are difficult to preserve.

In 1827 Louis Auzoux established his workshop in France, manufacturing human and veterinary anatomical models from papier-mâché. The company also produced botanical models, which were widely distributed to universities and schools in France, particularly to support the expansion in teaching agricultural science.

Beauty in the Eye of the Turtle Holder

Written by Becky Desjardins, Senior Preparator, Naturalis Biodiversity Center

Recently, we were cleaning up some mounted turtles and turtle shells destined to go in the new Live Science Hall. All of these came from Amsterdam Schipol airport, where they had been confiscated by customs agents.

When taking a closer look at these animals we noticed that none of these specimens had the normal glass eyes used in taxidermy. Instead they were made of other materials less commonly used for mounting animals.

Quite a few of the turtles had eyes made from shells. Some appear to be cowrie, but we could not identify them all, and a few other shells were painted black making them impossible to identify.

Then we came across one turtle with a glass eyes made from a marble. Funnily enough, they used a “cat’s eye” marble and the coloured core actually made the eye look quite lifelike.
