My first fieldwork from the OU, in 2005, was pollen trapping on the Galapagos. Here I am looking beardy on Bainbridge.
February was an exciting month for me principally because of the finalization of my move to the University of Amsterdam (UvA) where I will become head of Paleo and Landscape Ecology in September. The decision to leave The Open University (OU) has been a difficult one. When I joined the OU as a RCUK Research Fellow in Ecosystem Science in 2005 I would not have believed that I would be in a position to take on a job such as the one in Amsterdam only nine years later. Building the group here during the last nine years has been a lot of fun and I have got to work with some great people. Stand out moments include:
Obtaining my first grant as Principle Investigator (c. US$20,000 from the National Geographic for field work in Bolivia),
Recruiting, and graduating, my first PhD research students (Joe Williams and Macarena Cardenas),
Being invited to participate in large international research efforts (notably the Lake Bosumtwi project),
Co-editing my first book (Bush et al., 2011), having my first student to publish a paper getting it in Science (Cardenas et al., 2011), and helping to write a popular science text co-published by the Natural History Museum (Silvertown et al., 2011)
There have been many more amazing things here but I don’t want to swamp this post with a retrospective of my OU career…
Ongoing excitement within the PCRG is happening on a number of fronts:
I am delighted to announce that later this year I will be moving to the Institute of Biodiversity & Ecosystem Dynamics at the Universiteit van Amsterdam. I will be taking up an Associate Professor position as head of the Paleo & Landscape Ecology group. I am excited, and honoured, by this appointment and look forward to intergrating my ongoing program of research with the world class team in Amsterdam. Over the next few months I am sure further details will appear on the blog about the move as plans evolve towards my start date in September. Exciting times…
In the light of my departure, at that of Emma Sayer (bound for Lancaster), The Open University, Department of Environment, Earth & Ecosystems is now advertising two posts (details below). I have enjoyed my time at the OU and I think there are still good teaching and research opportunities for academics here. If anyone whats to contact me about the posts then I am happy to discuss.

Tardigrade egg found in Ghanaian pollen trap by Adele
Here is a summary of what other people have been up to:
Lottie Miller: submission and approval of thesis corrections (hooray), working on British Ecological Society grant application.
Hayley Keen: is finishing up lab work (macro charcoal – done, XRF – done, wood macrofossils – thin sectioned, awaiting identification, pollen – just 4 more samples!); and dealing with minor review revisions to first submitted paper (hooray).
Frazer Bird: finished the data collection for two Ecuadorian lakes (Banos and Pindo) and will hopefully begin to write up this data soon; attended the NERC stats course (very useful; would advise everyone to try and get on it).
Nick Loughlin: has split and logged the sediment cores recovered from Lake Huila (Ecuador) during recent fieldwork, and begun preparing the samples for pollen.
Adele Julier: has been preparing pollen trap samples from Ghana and learning tropical pollen.
Emily Sear: has mostly been on holiday and we are still waiting for the post card! She has also been working at getting results that make sense from the MS2.
Phil Jardine: has been oxidising spores to see what it does to the chemistry, generating FTIR data with the oxidised samples and starting the numerical analysis, and editing film footage from the 2013 Ghana trip.
Encarni Montoya: has been doing pollen lab and analysing pollen from Baños, and comparing the midges trends from Pindo and Baños with Frazer.
Wes Fraser: Reported back to Royal Society on finding from research grant – paper containing exciting results to follow in next couple of months.

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 🙂

MORE THAN MUD – What we can learn about past climate from lake sediments
“This film portraits international climate scientists investigating lake sediments for clues of past climate changes. Science is always teamwork. The INTIMATE Field School 2013 at Hämelsee gathered a variety of experts and young scientists from all over Europe to understand past climate change. The researchers retrieved a sediment core from a lake in Northern Germany, now being investigated using a variety of different analytical methods. A film team from the Babelsberg Film University HFF took part in this event. They accompanied the researchers and portrayed the diverse personalities and explored what motivates them and their research.”

Who would have thought that building a road in Andes would have allowed us to gain new and unique insight of pristine western- Amazonian forests? (I would have thought completely the opposite). Initially Patricia Mothes, chief of the volcanologist section of the Intituto de Geofisica in Ecuador, was called to look at sediments exposed by road works on the eastern flank of the Ecuadorian Andes. Arriving at the site she found thick (>20 vertical meters) deposits of grayish and dark brown interbedded layers of sediments which looked like they have been recently deposited. At closer inspection Patricia discovered that there were even wood pieces and leaves within the dark sediments (now known to be highly organic) that had the appearance of have been deposited within modern time. She wanted to know more. So a PhD student was recruited (a.k.a. Macarena Cárdenas) to work with the sediments at the Palaeoenvironmental Change Research Group at the Open University under the supervision of Dr William Gosling… And so the study began.
After several years spent dating the sediments, analyzing their composition (physical and elemental) and the fossils (pollen and wood) contained within them preliminary insights into vegetation change on the eastern Andean flank during the middle Pleistocene (c. 200,000-300,000 years ago) were revealed and published (Cárdenas et al., 2011a; Cárdenas et al., 2011b). Further work covering stratigraphically lower sediments (older than those previously published; c. 500,000 year) and more detailed sedimentary and fossil analysis of the entire sequence completed a PhD thesis (Cárdenas, 2011).
I am now pleased to announce that the extended work included in my PhD thesis has now been published in a new article in Palaeogeography, Palaeoclimatology, Palaeoecology (Cárdenas et al., online). The new paper is an extended version from previous publications from the same research and provides further evidence of the unique insights that can be gained from palaeoenvironmental studies in this region. These are some of the oldest Quaternary sediments ever discovered and studied from the mid-elevation eastern Andean flank / western Amazon and upon their analyses we were able to get for the first time an insight of how human-untouched Amazonian forests were back in time (up to 500,000 years ago!), how was their diversity and how they responded to intense volcanic activity and climatic change.

Hi, my name’s Nick and I’m joining the Palaeoenvironmental Change Research Group as a PhD student on a NERC funded project looking at the response of tropical forests to past changes in global climate.
I’m excited to be going off to Ecuador in November (with Encarni and Will) to undertake the sampling of lake sediments around the Estación Biológica Pindo Mirador and the National Park of Cayambe Coca, from which I hope to be able to determine changes in the ecology of the mountainous flora of the Andean regions of Ecuador during the last glacial and current interglacial periods.
I’m thrilled to be starting at the OU and am looking forward to splitting my time trekking through tropical rainforests and staring at microscopic pollen in a lab in Milton Keynes.
To date I have published one scientific paper, I hope to produce many more over the next few years…
