Advances in DNA sequencing technology are occurring at an incredible speed and Kevin Hopkins is one of the Museum’s Next Generation Sequencing Specialists working with the sequencing technologies used at the Museum to produce relevant data for our Microverse research.
“The challenge is being able to bring together the technology, often developed in biomedical settings, and the samples at the Museum, where limited and often damaged DNA from specimens is the only chance we have of sequencing them. My job involves designing methods that work for our unusual samples, extracting DNA and producing sequencing ready samples from it, and running our MiSeq and NextSeq next generation sequencing platforms.”
What is DNA sequencing?
DNA sequencing is the process of reading the order of nucleotide bases (adenine, guanine, cytosine and thymine) in a particular strand of DNA. Sequencing can be used for many different applications, such as defining a specific gene or a whole genome. The best way to sequence DNA is in sections; this is because there are a number of challenges to sampling the whole genome of a species in one go.
We take a diversion this week from the Microverse and our newest project, Orchid Observers, to introduce one of the projects that wouldn’t get anywhere without the general public reporting sightings, the UK Cetacean Strandings Investigation Programme (CSIP). Cetaceans are the infraorder of marine mammals that includes whales, dolphins and porpoises, and the Museum has been involved in recording their strandings on UK shores for over a century. So it’s over to Rebecca Lyal, Cetacean Strandings Support Officer at the Museum, to introduce the project and what she does as a part of it.
Warning: You may find some of the images that follow upsetting as they are of stranded and injured animals.
The CSIP was created in 1990 to unite the Museum with a consortium of interested parties to formally investigate the stranding of any cetacean, seal, shark and turtle upon the UK coastline. The Museum has actually been recording strandings since 1913 when the Crown granted it scientific research rights for the collection of data on the ‘fishes royal’.
The first recording was a Cuvier’s beaked whale that stranded in Northern Ireland during the summer of 1913. Since then there have been over 12,000 logged reports of whale, dolphin and porpoise strandings, that have ranged from the mighty blue whale to the common harbour porpoise, and even a rogue beluga whale found in Scotland.
The rich warbling song of the blackcap has welcomed us into work over the past 2 weeks! (you can hear an Eurasian blackcap, Sylvia atricapilla, as recorded by Patrick Aberg here). Not only that but we’ve had robins nesting just above the threshold of our shed with the accompanying chatter of baby birds anticipating food, holly blue butterflies visiting clusters of fresh holly flowers, sightings of orange tip, brimstone, peacock and speckled wood butterflies, tadpoles in the main pond, the occasional glimpse of a fox cub, and many more signs that Spring has well and truly sprung.
The mosaic of ground flora throughout the different habitats in the Garden is changing by the day with a particular blue haze and glorious scent of bluebells in the woodland areas.
Last month a new temporary display featuring some of our foraminiferal specimens and models was placed in the Museum gallery. This features real microfossils on one of our foraminiferal Christmas card slides alongside 20 scale models, part of a set of 120 models generously donated to us last year by Chinese scientist Zheng Shouyi.
As a curator dealing with items generally a millimetre or less in size I have not often been involved in developing exhibits other than to provide images or scale models like the Blaschka glass models of radiolarians. Displaying magnified models is one of the best ways to show the relevance of some of the smallest specimens in the Museum collection, the beauty and composition of foraminifera and to highlight our unseen collections.
The Museum’s Patron, the Duchess of Cambridge, gave birth to her second child just a few days ago, so the Museum’s online shop has been gearing up with gift ideas for newborns. With bibs, toys and T-shirts it’s never too early to introduce your littlest to the prehistoric world. We also take a look at some of the incredible facts about the first six months of your little hatchling’s life.
The date in the title of this post marks the sad passing of one of the Museum’s tiniest volunteers: in early February I discovered Beetah, my Carabus violaceous, lying still on her coconut substrate and to be honest, a little dried out.
OK, I have decided to create #WorldRobberFlyDay. All the time now, we hear that this large mammal or that large mammal has a ‘day’, and that got me thinking. Buglife have an Invertebrate of the Month, but even they are not very often the lesser-known insects, including the flies.
And I wanted global. Let the world celebrate! Why is it always the large stuff or the pretty (and, in my opinion, slightly less important) species? So I thought about it and decided it was about time that we championed more aggressively the rights of the small and endangered flies. These creatures are some of the most charismatic animals on the planet. The robberflies, or Asilidae, are truly worth celebrating for their looks, for their behaviour, for their good deeds to us, and because many of them are threatened.
The UK boasts 28 species of Asilidae (OK, so that’s not a lot in terms of flies, but hold on – we have only 30 native terrestrial mammals, of which 17 are bats and 2 are native marine mammals). Globally there are more than 7,500 species, and as such, it is one of the largest families of insects today. In fact Torsten Dikow, a world expert on this group, has them as the third most speciose group of diptera. This is a group, therefore, that has a large impact on the environment in which they live.
A great icon of British geology is celebrating its 200th anniversary this year. The William Smith map or ‘A Delination of the strata of England and Wales with part of Scotland’ brought revolutionary change to the way we think about the structure of the Earth and vastly advanced the science of geology.
Born in the Oxfordshire hamlet of Churchill in 1769, William Smith was the son of a blacksmith. Even though he did well at school there was never any thought of him attending university due to his family’s poverty.
A new and exciting citizen science project has begun and it’s time to get involved with Orchid Observers! This research project, in partnership with Oxford University’s Zooniverse platform, aims to examine the flowering times of British orchids in relation to climate change.
In order to achieve this, we are inviting the amateur naturalist and professional botanical community, alongside nature loving citizens from across the country, to help us collect and sort orchid data.
We want you to go out in the field and photograph any of 29 selected UK orchid species and upload your images onto our dedicated website, www.orchidobservers.org. Flowering times from each of your records will then be collated and compared with the extensive Museum herbarium collection, and data from the Botanical Society of Britain & Ireland (BSBI), totalling a 180-year-long time-series of orchid records.
In the final post in our series of blogs introducing our new trainees on the Identification Trainers for the Future project we meet Chloe Rose.
My name is Chloe Rose, I am 30 years old and have spent the last 10 years enjoying living by the sea in Brighton. After graduating in an Ecology and Biogeography degree I spent a year out travelling in South East Asia and New Zealand, marvelling at the wonderful flora and fauna.
Upon my return I began working for the RSPB at the South East regional office as a PA/marketing adminstrator and worked within the wildlife enquiry team. I jumped at the chance of many project opportunities throughout my 2.5 years there, such as project managing the Big Garden Bird Watch, and volunteering where I could at reserve events such as the Big Wild Sleep Out. During my time there I had the pleasure of working with a highly dedicated and passionate team who were devoted to saving nature.
