Principal Experience

Statistical analysis and interpretation of environmental data sets.

Alpine zoobenthic community ecology; altitudinal and longitudinal taxonomic zonation; the role of stream hydraulics, geomorphology and water quality in determining zoobenthic communities; patch-scale habitat utilisation; adaptive life history strategies to habitat templates; resistance and resilience of taxa to physical disturbance; population dynamics of the chironomid genera Diamesa.

The taxonomy of European alpine and British lotic invertebrates, and British riparian and in-channel macrophytes. The assessment of biological water quality as defined by macroinvertebrate, riparian and in-channel macrophyte communities.

The role of nutrient enrichment in chalk stream macrophyte-epiphyte dynamics. The transport of phosphorus within a eutrophic catchment.

Trophic relationships in a eutrophic brackish lentic waterbody. Population dynamics of the mysid shrimp Neomysis integer and the calanoid copepod Eurytemora affinis.

Competent in the use of analytical, statistical, graphical, database, word-processing and bibliography tools (e.g., S-Plus, ADE-4, SPSS, Canoco, Twinspan and ArcView).

Field survey techniques for benthic, pelagic and emergent macroinvertebrate communities in lotic and lentic habitats. Design of in situ chironomid rearing apparatus; field experimentation and biomanipulation techniques. Laboratory invertebrate feeding experimentation and life-cycle analysis. Reclaimed waste vegetation and timber survey techniques. Tree core analysis. Physic-chemical monitoring methodology. Soil profile description.

Well-developed written and oral communication skills for a variety of audiences.
