Qualifications:

BSc, MSc(Hons), PhD (Auckland)

Teaching Areas:

  • Marine Ecology
  • Aquaculture

Research areas:

  • Aquaculture – biology and ecology of cultured species, production, health and nutrition, feed development, re-circulating systems, water quality and waste management. Special interest in mussel ecology and aquaculture (largest aquaculture industry in New Zealand).
  • Estuarine/Rocky Shore Ecology – biodiversity, larval dispersal and transport, nutrient cycling, food webs, trophic interactions, shellfish reseeding. Special interests in community/ecosystem dynamics, and species-habitat ecology in New Zealand and Fiji.

Research Summary:

Dr Alfaro is an inter-disciplinary scientist with research interests in Marine Ecology and Aquaculture. Her research centres on understanding the complex interactions between organisms and their environments, in both natural (field ecology) and controlled (aquaculture) settings. Dr Alfaro's aquaculture work provides direct production benefits to industries in New Zealand and overseas. Her research on community ecology (i.e., food web dynamics) incorporates tools and approaches from a variety of fields (i.e., biotechnology, chemistry, microbiology, geology, statistics), and seeks to integrate physical and biological processes in space and time. She is particularly interested in the use of sound experimental designs and statistical approaches to construct rigorous quantitative studies in marine ecology and aquaculture production.

Current Research Projects:

Aquaculture:
  • Proteomics and cryopreservation of bivalve larvae
  • Immunology of cultivated shellfish
  • Probiotics to improve shellfish nutrition and health
  • Metabolomic applications in aquaculture production (bioinformatics)
  • Selective breeding - biochemical and genetic analyses
  • Physiological ecology of shellfish in growout environments
  • Seafood quality enhancement
  • Neurobiology and chemical receptors of invertebrates larvae
  • Hatchery production of marine invertebrate larvae, such as mussels, clams, abalone, scallops and other species of commercial importance
  • Reproductive behaviour and conditioning of marine invertebrates.
Marine Ecology:
  • Food wed dynamics and trophic interactions within estuarine and rocky shore ecosystems
  • Sediment geochemistry and physico-chemical processes in tidal estuaries
  • Hydrodynamic processes and sediment transport within estuaries
  • Nutrient cycling within mangrove ecosystems
  • Fish abundance, distribution and habitat use within mangrove stands
  • Carbon cycling and global change within mangrove ecosystems
  • Mangrove tree physiology, biomass and productivity
  • Eddy covariance data management and analyses
  • Ecology of complex biofilms on sediment surfaces
  •
