We have extended the deadline for applications for a fully-funded PhD studentship working on the long-term ecology of Congolese peatlands at the University of St Andrews. is 18 January 2019, which fits in with other NERC DTP deadlines. The studentship is available to start on selected dates between May and October 2019. For further details please see the project advert here.
A new NERC-funded five-year project to study the peatlands of the central Congo basin has been announced. The project, led by Simon Lewis at the University of Leeds/UCL, involves a multidisciplinary team from the UK and the RoC. Dr Ian Lawson of the University of St Andrews is leading Work Package 1, which aims to understand the genesis and history of the Congolese peatland complex.
The project kick-off meeting took place at Leeds on 6-7 September 2018.
The project is creating several new posts, including a PDRA and PhD studentship focusing on the palynology and other palaeoecological aspects of the project. The deadline for applications for the PDRA position has passed but for further information about the studentship, please contact Ian Lawson (firstname.lastname@example.org) or see the description online. Please note that full funding is only available to UK and some EU citizens – NERC eligibility requirements are here.
More information about this exciting project is available at CarbonBrief.
From April to July 2018 Greta Dargie, Jhon del Aguila Pasquel, Julio Iriarica and Ian Lawson have been busy in the swamp forests of the Pastaza-Marañón Basin setting up monitoring sites.
At two key sites, at Nueva York and Veinte de Enero, we have installed a suite of equipment and initiated measurements aimed at measuring litter production and decomposition rates. At 14 further sites we are installing automated dipwells and litter decomposition bags. The aim is to better understand why carbon-rich peat soils accumulate in some places and not others.
Christopher, Nina, Katy and Ian spent an interesting few hours surrounded by post-it notes, thinking through how to ‘code’ (analyse) the 51 interview transcripts, amounting to something like 150,000 words, generated by our SFC-ODA project on valuing peatlands in Amazonian Peru.
Many interesting themes emerged – not least the myths, legends and superstitions that surround wetland environments in Peru – just as they do in the UK. We are also interested in themes such as resource use, sustainability, and gender issues.
Now that the decision has been taken about what to look for in the transcripts, the hard work of analysis will begin…
An article building on Tom Kelly’s PhD research at Lake Quistococha has appeared in The Conversation.
A new paper by Tom Kelly and other members of the Tropical Wetlands Consortium has just appeared in Journal of Quaternary Science.
As part of his PhD work, Tom showed that the lake at Quistococha, on the outskirts of Iquitos in Peru, contains a remarkable pollen and microcharcoal record. The data show an increase in pollen of the disturbance indicator Cecropia over the past century and a half, presumably reflecting the growth of Iquitos. Prior to that, the pollen record suggests little change in forest cover, despite a continuous microcharcoal record suggesting the presence of human populations.
A critical piece of evidence supporting our interpretation of the microcharcoal as an indicator of human presence was provided by co-author and archaeologist Santiago Rivas Panduro, who had previously published the results of excavations at an archaeological site adjacent to the lake. There, pottery, plant remains, and radiocarbon dates provide unequivocal evidence for prehistoric human occupation.
We suggest that the new record helps to support an emerging understanding that, in the wettest parts of Amazonia, there may have been little deforestation before modern times. This is an important qualification to the growing body of evidence from more seasonally-dry parts of the Amazon Basin which suggest that there, much of the forest had been cleared, at least episodically, in pre-Columbian times.
The article is published here.
During a project planning meeting in Iquitos Tim Baker, Ian Lawson, Santiago Rivas Perez and Euridice Honorio Coronado took the opportunity to present our recent work on Quistococha (Kelly et al. 2018) at the Ministry of Culture in Iquitos. We also appeared twice on local TV – a fun experience!
Freddie Draper and colleagues have a new paper in Ecography, online as an accepted article.
The paper, Peatland forests are the least diverse tree communities documented in Amazonia, but contribute to high regional beta-diversity, uses floristic data from a network of plots to show that peatland palm swamps and pole forests host distinctive floras.
Although, at the plot level, peatland forests are typically much less diverse than dry-land forests, the paper argues that they make a substantial contribution to regional beta diversity which, together with their dense below-ground carbon storage, enhances the case for conserving them.
This paper grew out of data and analyses conducted by Freddie during his NERC-funded PhD.
Our new NERC-funded project officially begins today, with the appointment of Dr Greta Dargie as a PDRA at St Andrews. Greta will be leading field and lab data collection, initially working with colleagues at IIAP in Iquitos.
Greta has been in the news recently in relation to her pioneering work in mapping Congolese peatlands: http://www.theguardian.com/environment/2017/nov/12/congo-basin-swamps-peatlands-carbon-climate-change.
Dr Katy Roucoux, Prof Nina Laurie and Dr Lera Miles (WCMC Cambridge) have been awarded a NERC CASE studentship to start in 2018 on “Human impact in Amazonian peatlands”.
Application details will appear soon at http://www.st-andrews.ac.uk/gsd/opportunities/pg/phdfunding/.
