Collecting Seaweeds in Ireland

Katie Mortimer-Jones, 10 April 2014

By Kath Slade

The marine team are back from their fieldwork to West of Ireland with lots of specimens to sort through, including seaweeds. The timing of fieldwork was chosen to coincide with several very low tides, allowing us to sample species lower down the shore, which are less adapted to long periods out of water. We still had limited a time to sample around low water (approx. 2 hours).

The lower shore holds many of the red seaweeds, such as Sea Beech (Delesseria sanguinea), Fine-Veined Crinkle Weed (Cryptopleura ramosa) and Bonnemaison’s Hook Weed (Bonnemaisonia hamifera).

Immediately after collection, there was a fair amount of processing to do, as seaweeds don’t last long out of their natural habitat on the shore. Many were floated out in trays of seawater in order to spread all of the fronds (“leaves”) out, before being transferred and pressed onto conservation grade cotton paper. The specimens were stacked together, and between each layer we had blotting paper to soak up the water. The stacks of seaweed were then placed into large plant presses, just like those used for flower pressing. Each day the blotting paper was changed to remove as much water as possible. When we returned to the Museum, we placed the plant presses in drying machines to speed up the process and prevent the seaweeds from rotting.

Some seaweeds are difficult to identify from external characters alone. For these species, small portions were collected and placed into silica gel. This dries the seaweed much quicker than pressing so that the DNA is better preserved enabling molecular work to be carried out at a later date. Others were preserved in formalin, which removes the colour of the seaweed but preserves the cell details and the seaweed’s 3D structure. Further identification work, will now be carried out back at the Museum.

All this preparation allows us preserve the seaweeds for future scientific studies. The specimens go into the Welsh National Herbarium (plant collections) at the Museum, and each provides evidence of what seaweeds are present at a particular locality at a particular time. The pressing process is so effective that specimens keep for hundreds of years.

Fieldwork in Co. Mayo - Update

Katie Mortimer-Jones, 8 April 2014

The team are now back from the West Coast of Ireland and the trip has proven to be really successful. The team continued to sample around Corraun, near Achill Island, north Clew Bay for several days, although the weather did turn. They are now processing the samples collected back at National Museum Cardiff. The seaweed samples are carefully dried and pressed, bristleworm and shell specimens are removed from the formaldehyde fixative and then placed into alcohol, and the DNA samples are placed into the freezer. Once processed the specimens will become part of the Museum Collections, and will contribute greatly to the research of the Natural Sciences department.

TOP 10 garden birds

Catalena Angele, 7 April 2014

Hi bulb buddies!

Big Garden Birdwatch results

Which are the TOP 10 most common birds in your garden? Nearly half a million people helped the RSPB (Royal Society for Protection of Birds) with the Big Garden Birdwatch 2014. They counted over 7 million birds! Did you help? If not then maybe you can do some bird spotting and join the Big Garden Birdwatch next year? To find out which birds were in the TOP 10, click here

Which schools have had their first flowers?

Trellech Primary School in Wales, and Britannia Community Primary School in England sent their first flower records. Well done and thank you to these schools!

One of my colleagues her at National Museum Cardiff sent me this photo of daffodils growing in her garden, can you see anything strange about them? The photo is a little fuzzy but if you look closely you will see that some of the stems have two or even three flowers! How unusual! Have you had any unusual plants?

Thank you to SS Philip and James CE Primary School for sending me this lovely photo of all their flowers, don’t they look wonderful? In the third photo you can see that they also had some unusual flowers - some of their daffodils did not fully open. This is very interesting, can you think of any reasons why they might not have opened? Did this happen to your flowers?

Daffodil man!

Would you like to see a funny photo of Daffodil man? Click here. His real name is James and he is wearing a suit of daffodils to raise money for charity! Well done daffodil man!

Your comments, my answers:

Prof P: I had lots and lots of comments from Dallas Road Community Primary School so I thought I would put them all on the blog this week, thank-you all for sending me your messages! Congratulations to all of you, even if your flower did not grow, was stepped on, got broken or died, you are ALL Super Scientists! Prof P.

Dallas Road Community Primary School: 

I think it didn't open because the daffodil was hovering over it and so it didn't get enough sun and rain. :(

I think my daffodil was in the shade so it did not open.

Someone cut its head off

It didn't open because somebody stepped on it

It died

Someone broke the bud off

Mine did not open!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

My Bulb disappeared

It was a bit floppy so we did not get chance to tie it up. But it is still open.

I am quiet sad my daffodils have not opened but they are growing so I will believe that soon they will and they are really tall.

My daffodil is growing very tall but it is a bit floppy.

My crocus is beautiful some of them are starting to die but still i'm happy because some are still growing and some have opened and some of them are fully beautiful i'm really happy about every crocus. My crocus's are quiet tall some are small as well

my crocus is really beautiful i have got another 3-4 crocuses opening i really enjoy seeing my plant grow.

My crocus has flowered well and is growing quite tall which is good and happy about it all.

I did not get a daffodil so it did not grow.

Daffodil has broke and I had to tie it up.

My plant head fell off. I haven't seen it since so I don't know if it has grown back.

My daffodil didnt open. I dont think mine had enough sunlight

Prof P: Culross Primary School sent me messages to tell me they had named their flowers, thanks Culross! Here are some of the names they gave their Daffodils and Crocuses: Danny, Dafty, Crocy, Abby, Croaky, Dave, Chris, Cassy, Ceeper, Bob, Jim.

Many thanks,

Prof P

On fieldwork in County Mayo

Jennifer Gallichan, 2 April 2014

Six members of Natural Sciences staff are currently on fieldwork in Co. Mayo, Ireland. After attending the 2 day Porcupine Marine Natural History Conference at the Ryan Institute, National University of Ireland Galway they set off for Co. Mayo for 5 days of intertidal fieldwork. Their primary interests are in marine bristle worms (polychaetes), bivalve shells (molluscs) and seaweed.

After setting up a temporary laboratory the scientific team have spent the last two days visiting several shores in Clew Bay and Blacksod Bay — following in the footsteps of those who carried out the historic 'Clare Island Survey' in the early 1900s. Samples are being processed for both morphological and DNA work contributing to the Museum's collections and research programme. Many live animals and algae are being photographed. Today the team is setting off to Corraun, near Achill Island, north Clew Bay. They will be joined by Fiona Crouch of the Marine Biological Association UK, who has been extending her 'Shore Thing' community science programme to Ireland (as ShorTIE).

Deadline Day!

Catalena Angele, 28 March 2014

The Spring Bulbs deadline has arrived! I would like to say a HUGE thank you for working so hard to get all your weather and flower records in to me on time.

Which schools have had their first flowers?

Balcurvie Primary School, Chatelherault Primary School, Glencairn Primary School, St. Blanes Primary School, St. Patrick's Primary School, Tynewater Primary School and Wormit Primary School in Scotland, and Brynhyfryd Junior School, Cleddau Reach VC Primary School, Coed-y-Lan Primary,St Athan Primary, St Mellons Church in Wales Primary School, Ysgol Bro Eirwg, Ysgol Iau Hen Golwyn and Ysgol Y Plas in Wales, have all seen their first flowers open. In England, Bleasdale CE Primary School, Combe Primary School, Cutteslowe Primary School and Flakefleet Primary School, all sent their first flower records.Well done and thank you to these schools! 

Keep sending in your flower records!

As I said in my blog last week, if your plants have flowers but they have not opened yet, please keep watching them and send me your records when they open. They will not be in time to be in this year’s Spring Bulbs Report, but they will make next year’s report more accurate.

What if you didn’t have a flower?

Thank you to all the pupils who have sent me a record to say their plant did not flower, or that their flower did not open (you can do this by clicking ‘Didn’t open’ in the Flower Record). I know it can be a bit disappointing if your plant does not flower. But please don’t be sad! One thing that a Super Scientist must learn is that experiments don’t always work out the way we want them to! This does not mean that the experiment has failed. For a scientist it is JUST AS IMPORTANT to record when something does not happen, as when it does.

You will get a Super Scientist certificate and pencil if you worked hard and helped with the Super Scientist Investigation – whether your flower opened or not!

Wildflower Meadow at National Museum Cardiff

Here at National Museum Cardiff we are experimenting with growing a wildflower meadow. Do you have a wildflower meadow at your school? We have planted some seeds and bulbs and the first flowers to appear have been crocuses and daffodils! Here is a picture of them. It doesn’t look much like a meadow yet does it? But hopefully by the summer it will look very different. The muddy circle is where we have planted lots of red Poppies to remember the First World War. This year it is the 100th anniversary of the start of the First World War and here at Amgueddfa Cymru – National Museum Wales, we will have events and exhibitions that tell the stories of the people of Wales during the War. Click here to find out more.

Your questions, my answers:

Dallas Road Community Primary School: Hi Proffeser Plant!! Prof P: Hi everyone at Dallas Road!

Pinfold Primary School: nearly all the bulbs have opened. The mystery bulbs are blooming very well. The crocus is growing purple flowers. Prof P: What were your mystery bulbs Pinfold?

Glyncollen Primary School: Hello Professor Plant, We're excited because our bulbs have now sprung and we can't wait to get our certificates. From, Year 4. Prof P: Congratulations Year 4! I look forward to sending them to you, you are Super Scientists!

Ysgol Terrig: Our Bulbs have opened and they are 15cm tall :). Prof P: Great measuring Ysgol Terrig.

Rougemont Junior School: What a warm a dry week Professor Plant, our crocuses are all blooming as are our daffodils. Prof P: All the colours look so lovely don’t they?

St. Ignatius Primary School: We have uploaded our weather records for this week but unfortunately our bulbs have not flowered just yet. We are disappointed as this is the last week and we can see them coming along but not as quick as we would have hoped. We will continue to keep an eye on them and let you know when they have flowered. Our teacher will need to do this next week as P7 are off to Kilbowie in Oban for an outward bound trip. Prof P: Please don’t be disappointed P7, your results are still really important, even if your flowers didn’t open by the deadline. Enjoy your trip it sounds like fun!

Kilmaron Special School: We are using the findings of our daily temperature readings and rainfall as evidence in our SQA National 1 Measurement unit. Prof P: That is fantastic Kilmaron, I am so glad it is helping you with your qualification.

Stanford in the Vale Primary School: Thank you very much we really enjoyed it and are datherdils are blooming and are very healthy and strong through all of these conditions. Stanford in the vale gardening club. Prof P: I am so glad you enjoyed it Stanford, that makes me very happy!

St. Blanes Primary School: Hi Professor Plant, the start of the week felt much warmer. It's the first time we saw the temperature in double figures! Prof P: I hope you enjoyed the warm weather.

Gladestry C.I.W. School: it has grown well i'm a mum. Prof P: Congratulations! You must have looked after your baby bulb very well.

Chatelherault Primary School: Some of our plants are starting to bloom the daffodils are showing the most. The crocuses are still growing but not as much as the daffodils. Prof P: That is very interesting as crocuses usually flower before daffodils.

Ysgol Gynradd Cross Hands: Dyma ein blodyn cyntaf gan LM o Ysgol Gynradd Cross Hands. Mwy o haul plis!Prof P: Llongyfarchiadau LM o Ysgol Gynradd Cross Hands!
