Millennial-Scale History of Amazon Forest Dynamics

Background

Studies of a network of 1-hectare forest plots across Amazonia have revealed significant ecological changes (e.g. increasing biomass) over recent decades, but whether they reflect atmospheric change (e.g. fertilization from rising CO2 concentrations), or instead secondary succession following pre-Columbian (pre-AD1492) human disturbance, is controversial.  Furthermore, the likely impact of increasing drought over the 21st century, predicted by climate models, is also uncertain.  A palaeoecological approach can potentially reveal the impact of mid-Holocene drought (a potential analogue for future drought) as well as Pre-Columbian land use.  However, a major disadvantage with lake-based pollen analysis (the traditional palaeovegetation proxy) is that suitably old lakes are rare in Amazonia, and the spatial resolution of pollen records is generally far too coarse to enable meaningful comparison with ecological data from 1 ha plots.  The aim of this project is to circumvent this problem by using a novel suite of palaeoecological proxies from soil profiles to reconstruct the millennial-scale vegetation histories of individual 1 ha plots of different types of forest across ecotonal southern Amazonia.

 Assessing the resilience of Brazil’s iconic Araucaria forest

to past and future climate change

Co-supervisors: Richard Walters, School of Biological Sciences, Univ. Reading; Joy Singarayer, Dept. Meteorology, Univ. Reading; Macarena Cárdenas, Dept. Geography & Environ. Science, Univ. Reading.

 

Applications are invited for the post of Graduate Teaching Assistant. The appointed person will be registered for a Part-Time PhD, while holding a contract of employment from the University of Reading which encompasses both doctoral studies and teaching responsibilities with an associated salary. The post will commence on 19th September 2016, for a period of 4 years. Although six potential topics are being advertised, only one post will be appointed to the strongest candidate.

Teaching duties: The appointed person will be expected to deliver seminars and tutorials to groups of 10-20 students on a regular basis, to undertake assessment marking and to undertake undergraduate dissertation supervision. They will be expected to complete the required training and development activities as specified by the Department, achieving AFHEA status within the first two years of appointment. Teaching duties will not exceed nine hours of teaching and learning work (of which no more than six will be contact hours) during term time.

The Parana pine (Araucaria angustifolia) of southern Brazil is an iconic ‘living fossil’, dating back to the Mesozoic. This evergreen conifer once dominated highland areas of Brazil’s southern Atlantic Forest (a global biodiversity hotspot), but is now critically endangered due to extensive deforestation and is, therefore, a conservation priority for Brazil. To understand its response to future climate change, a better understanding of the reasons for its current biogeographic distribution is needed, which can only be gained via knowledge of the long-term history of this species over several millennia. Was the documented expansion of Araucaria forest over the last several millennia a response to increasing rainfall, or a function of pre-Columbian indigenous peoples enabling its expansion due to its economic importance? To tackle this question, a novel multi-disciplinary approach is needed, which integrates palaeoenvironmental and archaeological data with ecological-climate modelling studies.

Prof Frank Mayle at the Dome

Amongst the many other activities that our members of TPR do, enlightening young people about the great opportunity of studying environmental sciences is one of them.

Today we found our Principal Investigator Professor Frank Mayle  (photo below) taking part in this important task.

With just some hours left before he goes on field trip Frank is found with hands on flyers and coffee and a large smile at the Dome, University of Reading

 

Open Days are great opportunities for young students that are considering to study with the university and that want to talk to the academics that teach and do research here. They can also find many current students of the university from the various qualifications offered to ask questions related to modules, living in reading, about social life and other activities.

A full-on and sunny day for Frank (who is due to leave to Fieldtrip in Bolivia 2016 in just some hours!)
