The cellular basis of an ecosystem engineer
A fully-funded 3-year PhD position is available for a motivated and curiosity-driven student to study the cell and developmental biology of the peat-forming moss, Sphagnum.
Peatlands play significant ecological roles in terms of atmospheric carbon sequestration into
peat, CO2 and methane release, as well as wildlife conservation and water dynamics.
Under suitable conditions, Sphagnum becomes the climax vegetation and can even displace larger vegetation including forest, to form extensive peatlands. Peatlands act as net carbon sinks, storing an estimated one third of the worlds soil carbon. Thus, Sphagnum accounts for more accumulated biomass than any other genus on earth. Sphagnum also holds more water per unit biomass than any other common terrestrial plant and modulates water movement through many of the landscapes in the western regions of the UK and the European mainland. Human activity has contributed to extensive destruction or degradation of peatland leading to restoration projects aimed at re-establishment of a healthy bryophyte community to improve water quality and ecological diversity.
The interaction between Sphagnum and water is therefore fundamental to its role as an ecosystem engineer, but very little is known about the genetic and molecular basis that underlie this remarkable adaptation.
This PhD project therefore will exploit advanced imaging, physiological and phenotyping methodologies to survey morphological variation in the Sphagnum genus and identify features that influence the plants’ interaction with water. The student will work alongside an experienced Post-doctoral Research Assistant on the project and also receive specific advanced training from experts in relevant aspects of cell biology, genetics, and automated large scale photo-physiological phenotyping. Classical plant systematics training will be provided by expert bryologists, complemented by DNA bar coding from molecular systematics researchers at the National Botanical Gardens of Wales. Location
The student will be based in Aberystwyth University at the National Plant Phenotyping Centre within IBERS, and will have the opportunity to interact with restoration ecologists in the Welsh uplands, the UNESCO designated Dovey Biosphere ( http://www.unesco-mab.org.uk/biosffer-dyfi-biosphere.html www.dyfibiosphere.wales/ ) the Pennines and Ireland.
This exciting PhD project, therefore, will provide training in a broad range of biological techniques and transferable skills at the highest level. Moreover, the student will interact with experts across Europe and present their work at local, national and international conferences.
