So we’re back from a hot and humid Ecuador to the joys of a British winter. Ecuador is an amazing country and the diversity of the flora and fauna surpasses anything that I have experienced before. Continue Reading

PCRG October to December

December 20, 2013
WDG

The latter half of 2013 seems to have been incredibly busy and I have not managed to get my monthly update posts completed since October. Rather than a rapid series of backdates here is a quick summary of what I think the main activities through this period have been!

Thesis defence: Congratulations to both Lottie and Natalie for sucessfully defending their PhD theses! Exeptional effort and hard work from both of you. Well done.

Publications: Four articles have gone through the final stages and been published in top journals. Well done to Lottie, Maca, Wes for leading three of those publications covering Lake Bosumtwi, Erazo and pollen/spore chemistry respectively. Personally I am delighted that the revised tropical pollen atlas is now online and open access. The final stages of publication of the atlas with Review of Palaeobotany and Palynology were hard work but great to see it online and avaliable. Thanks to Lottie and Dan Livingstone for their invaluable contributions.

Grant: We have been awarded further 14C dates from NERC radiocarbon facility to improve the chronology on Laguna Khomer Kotcha Upper so that the timing of temperature osscilations revealed by new chironomid analysis (by Frazer Bird) can be related to the last global degalciation (c. 18,000 years ago) and the Younger Dryas cooling event (c. 12,800 – 11,500 years ago). This research builds on that of former PCRG PhD student and current research collaborator Joe Williams (Williams et al., 2011; Williams et al., 2012).

Teaching: I have been working primarily on the Geological record of environmental change (S369) presentation, and writing the landforms section for the new level 2 environmental science module.

Fieldwork: Trips to Ghana (Adele and Phil) and Ecuador (Nick, Encarni and Will) have been super successful; AND all the samples have made it back! See posts elsewhere on the blog for details of field work fun.

I am sure other stuff has happened… more in the New Year… and maybe some more pictures when I can get back on my newly “optimized” (killed) office computer 🙂

Three members of the PCRG (William Gosling, Encarni Montoya and Nick Loughlin) visited Ecuador (November-December 2013) to develop collaborations with Ecuadorian institutions, recover more lake sediments, and find new potential sites for projects. Below are some photos from:

  1. Lake Pindo, 
  2. Lake Huila, and
  3. Lake Erazo.

Full reports on specific aspects of the fieldwork to follow.

Having been away for half of the month I asked people to provide a summary of what they have been up to. Here is what they admitted to…

Natalie Ludgate and Lottie Miller have submitted their theses! Well done.

Hayley Keen: “Continual pollen counting, second lot of Argon dating done, and first set of wood macrofossils back and ready for identification!”

Frazer Bird: “At the start of September I began working as a technician as part of Encarni’s project. I am looking at the midges from the core we collected together on our last field trip. Things are going well, although the midges are hard to find in the older sections the preservation in early sequences is great. The resolution of this core looks to be fantastic also so and hopefully we will get some interesting results when we compare all the proxies.   Away fromthe lab I presented at INTECOL 2013 in London, The talk seemed to go down well and was noted as highly commended by the judging panel. Great publicity all round for the midges!!!”

Bryan Valencia: Has been on field work in Peru during this time he presented a talk on climate change to the Asociación para la Conservación de la Cuenca Amazónica, and gave interviews to local journalists and two TV stations. He also collected sediments from two locations, and manged to obtain a new US visa. He is now working on the final stages of submitting his thesis.

Phil Jardine: Phil has been busy ordering in microscopes and other equipment for the Lake Bosumtwi project (the first of which arrived today), and setting up the trip to Ghana that he’ll be going on with new PhD student Adele Julier in late October. He’s also been attempting to learn more about geochemistry, which has proved challenging.

Encarni Montoya:

  • Lake Pindo: We have finally the results of 6 samples radiocarbon dated from NRCF through our collaborator Dr Pauline Gulliver, and we have sent 4 more to “range find” the key interval of interests for the FORSENS project. We have started the midges’ analysis although it seems this going to be focused to the upper 4 meters of sediment. We would like to discern possible preservation issues in tropical records for this proxy. Some samples for a preliminary screening looking for diatoms ahve been collected and sent to the new FORSENS collaborator Teresa Vegas-Vilarrúbia. MS samples have been also collected for the first three drives and we hope to run this analysis next month.
  • Lake Banos: We have started the pollen prep. for the upper section of the record.
  • Management tasks: We are now ready for the tropical record Lake Marcacocha pollen prep., collaborating with an ongoing project lead by Alex Chepstow-Lusty. On a different topic, I have started the organisation of department seminars, so I would like to highlight if you have any potential speaker, please contact me.
  • Publications: a co-authorship in a paper published in Perspectives in Plant Ecology, Evolution and Systematics authored by Valentí Rull and his research group in the Botanical Institute of Barcelona is now available on line (click here)

William Gosling: “I have been promoted to Senior Lecturer (hooray), started work on the new level 2 environmental science module, been working on a new paper from the Erazo study site, and had a holiday!”

August was a month for travel with PCRG members heading for Peru (Bryan, and he is still there), Greenman festival (William), INTECOL conference (William and Frazer), and the Royal Geographic Society annual meeting (William, Encarni, Frazer and Hayley). Detailed reports of the UK based travels are already on the blog, and hopefully we will get a post from Bryan on his Peruvian adventure once he is back.

Back in Milton Keynes work progressed with:

  • Hayley producing a revised full draft of her pollen counting methodology manuscript,
  • Frazer starting with the first tentative attempts to apply his chironomid training data set to fossil chironomid records,
  • Phil trialing inverted microscopes and training on the FTIR,
  • Encarni plotting field work in Ecuador (more travel for November-December),
  • William seeming to spend alot of time working on research strategy for the faculty, and thinking about writing teaching material for the ongoing revison of our level 2 environmental science module, and
  • most excitingly of all, Lottie submitting her PhD thesis! WELL DONE LOTTIE.

Four new workstations installed in the Past Environmental Change microscope lab

Four new workstations installed in the Past Environmental Change microscope lab

Excitement in February saw the arrival of a new research grant within the PCRG, to look at pollen and spore chemistry from Lake Bosumtwi (watch this space for new post-doc and PhD studentship positions), and (just in time) the expansion of benches in the microscope lab which will ensure that the new people will have spaces to sit in! In addition, we had a paper published with long time friends and collaborators at the University of Leeds; Roucoux et al. (2013).

Despite the disruption of the lab refit Hayley and Frazer have been cracking on with pollen and chironomid analysis. Encarni and Frazer returned from field work in Ecuador and half the samples have so far made it back to The Open University; we now wait with anticipation for customs to release the other box!

Four shiny new benches from the other side

Four shiny new workstations from the other side – woo

Meanwhile I have been working on exam questions for the Geological Record of Environmental Change module (S369), interviewing prospective PhD candidates for the October 2013 start projects and have been on a training course to learn about the Vitae support for research student training.

The last two months of 2012 were exceptionally busy! 

On the research front

On the teaching and administration front

Two tasks dominated the non-research activity: 1) teaching the Geological Record of Environmental Change (S369) exams assessment and assigment, and 2) as Post Graduate Tutor keeping up with NERC developments for the new Doctoral Training Partnerships.
