Saltmarshes are environments located at the interface between land and sea, which are regularly flooded by the tides and where the plant community is comprised of salt tolerant plants. The area around the UK covered by saltmarshes has decreased considerably during the past centuries due to land-claim for agriculture, urbanisation or industry. Saltmarsh restoration schemes have been implemented across the country to counteract this loss. Different parameters are typically surveyed to assess the success of a saltmarsh restoration scheme, such as species diversity and sediment accretion. However, assessment of the structure and diversity of intraspecific variation has been largely overlooked during saltmarsh restoration.
My project aims to look at the population genetics of three saltmarsh species (Triglochin maritimum, Aster tripolium, Puccinellia maritima) in order to investigate the development of genetic diversity and structure in restored saltmarshes around the United Kingdom.
The questions addressed during my PhD are:
- What is the extent of genetic diversity within these three species around the UK?
- Are there differences in genetic diversity and structure between restored and natural saltmarshes?
- Where do colonists arriving on a newly restored site come from?
