The second part of our Ecuadorian expedition took in lakes and sections close to the towns of Papallacta and Cosanga. The variation in climatic conditions was marked as we experienced first hand the transition from freezing fog and driving rain to burning sun and heat within a few tens of kilometers as we travelled from >4000 m down to around 1000 m elevation.
Tomorrow we will attempt to recover short cores from two more lakes. Then our final few days here in Ecuador will be spent visiting partners and packing up.
We have now spent two days in sampling sedimentary sections near the Rio Tigre close to Mera in Ecuador. The sections are peat deposits interspersed with volcanic ash and contain many wood macrofossils. It seems likely that the depositional environment was a shallow water swamp or bog. Although we will have to wait for the analysis of the fossil record to know the composition of the vegetation at the site.
I am writing this August post from the Hotel Rincon Escandinavo (Quito, Ecuador) most of this month has been pretty hectic as we have been preparing for this field work trip and trying to get as many things out the way before hand.
We seem to have been quite involved in conference activity: Lottie presented “500,000 years of vegetation change from West tropical Africa” at the International Paleolimnology Association Symposium in Glasgow, Hayley had an abstract on “Pollen counting for diverse tropical ecosystems” accepted for the Linnean Society Palynology Group meeting (1 November) and group members also submitted abstracts for consideration to be presented at the American Geophysical Union Congress and British Ecological Society meeting (both in December); fingers crossed these will be accepted as well.
Regarding the field work. Preparation seems to have gone well and we have arrived in Quito with all out bags, despite a short (1 hour) connection in Madrid. Tomorrow we will meet up with Dr Patricia Mothes (Instituto Geofisico) and set out our detailed plans. As I have now been up for more than 24 hours I should probably get some sleep… Plan is to blog more about the trip as it happens.
I have been really excited with the increase in the number of posts and various contributions to this blog over the last month or so. So thanks to everyone who has contributed. The excellent content allows me to focus on just a few research and teaching events which have not been previously covered.
1) Welcome to Wesley Fraser who has joined us officilally as a visiting postdoc for a few months. We hope to develop a paper and another grant submission looking at pollen/spore chemistry during this time; for further details see “Do plants wear sunblock” post.
2) Well done to Frazer and Hayley for performing well in their end of year 1 mini-vivas. Both projects are progressing well and we are all looking forward to field work at the end of the month. Hopefully most of the prepartation and equipment are now in place…
3) Potential for more exiting collaborations was also developed at two meetings. The first, at the Natural History Museum and, in conjunction with long term collaborator Steve Brooks was with old friends Mick Frogley (Sussex) and Alex Chepstow-Lusty. Both Mick and Alex taught me when I was at Cambridge and it would be super exiting to develop a new collaboration with them looking at Chironomids in Andean lakes. The second was at the Univesity of Nottingham as I took part in a UK Tropical Peatlands meeting which brought together ecologists and palaeoecologists from Nottingham, Leeds, Leicester and The OU. The aim of the meeting was to coordinate papers and grant applications.
4) At the end of July beginning of August I taught on the “Sedimentary Rocks and Fossils in the field” topic for the new Practical Science, Earth & Environment (SXG288) module which The OU now offers. Longridge Towers School (no children around this time of year) provided the perfect base for investigating the sedimentary geology of the region. The small group of students had the opportunity to make field observations and test hypotheses related to past environmental change. Everyone was very excited to find numerous fossils and interesting sedimentary structres and had fun trying to work out what they all meant! Congratulations to Angela Coe for putting together this great event.
I whish I could start with “ Once upon a time…” because that would be the easiest way to begin this paragraph (or a paper). Besides, to some extend, “Once upon a time” can be appropriate because this is a story related to the OLD friends of the Paddington Bear. By that, I mean a story about the mega fauna in South America.
