Research

Interests

Diatoms are unicellular algae that are characterised by the possession of highly structured siliceous walls. They are probably the most successful group of algae, being found throughout the world, in both marine and freshwater systems, as well as subaerial and terrestrial habitats. It has been estimated that they contribute at least 20-25% of primary production in the world.

My work can be summarized under four project headings:

  • Development, variability and control of the diatom phenotype
  • Systematics of naviculoid diatoms
  • Use of cytoplasmic features for diatom identification
  • Use of diatoms as environmental indicators

Development, variability and control of the diatom phenotype

Diatom cells have a unique wall structure in which the two halves of the siliceous ‘box’ enclosing the cell are formed at different times. Each cell has an older and a younger half wall (valve), but both are formed under the control of the genotype and morphogenesis follows a particular order in each taxon. However, if genotypic expression varies with environment, the resulting phenotypes will differ according to conditions at the time of formation. Thus, it is possible that if the two valves of a single cell developed under different external conditions they will differ morphologically. Understanding how particular valve features are formed, and under what conditions they can be transformed is important for their interpretation for systematic analyses.

 

Systematics of naviculoid diatoms

I am particularly interested in the generic relationships of naviculoid diatoms and how well the current diatom classification reflects those relationships. Recent work has included studies of the relationship between the monoraphid genus Achnanthes and the Mastogloiales, as well as an investigation of the marine genus Proschkinia.

 

Use of cytoplasmic features for diatom identification

Diatoms have traditionally been identified on their wall characters after cells have been ‘cleaned’, i.e. the organic components have been removed by oxidation. However, this means that assemblages analysed from such material may include cells that were not alive at the time of sampling, or were washed-in from other habitats. This may skew ecological interpretation based on the assemblage.
However, it is possible to identify many diatoms from fresh, living material using cell contents, particularly chloroplast arrangement.
I am currently working on a revision of my book “Identification of freshwater diatoms from live material” and will be incorporating a CD of photomicrographs in the second edition.

 

Use of diatoms as environmental indicators

Because their cell walls are well-preserved in many sediments, diatoms have been used extensively as palaeo-ecological indicators of pH, trophic status, salinity, etc. They are also widely used as bioindicators of contemporary conditions (especially under the Water Framework Directive). This work has relied on correlations between assemblage composition and measured field conditions, rather than empirical evidence of species responses to particular environmental variables.
I have used an experimental approach to determine whether inferred relationships based on field data are supported by growth responses in the laboratory.
