Research interests:                                                                    

  • Salt marsh and estuarine ecology
  • Wetland and estuarine restoration
  • Trophic relationships of marine and estuarine macrofauna
  • Ontogenetic shifts in foraging and habitat use patterns

Past projects:

  • Abundance and distribution of larval and juvenile salt marsh fishes in the Sister's Creek marsh system
    • Larval and juvenile fishes are collected from the salt marsh surface using pit trap collectors.  I am interested in the effects of salt marsh vegetation composition on larval fish abundance
  • Study of estuarine habitat use by nekton in the Sister's Creek marsh system  - view sample organisms found within the estuarine system
  • The role of complexity of oyster reef habitats on juvenile fish abundance and survival within the Guana-Tolomato-Matanzas National Estuarine Research Reserve.
  • Determine large-scale patterns of abundance for resident salt marsh fishes, based on habitat specific abundances

Student opportunities:  student involvement in my research is strongly encouraged - UNF biology majors can earn independent study credits, and student volunteers are welcome. I am happy to mentor students in projects related to marine and freshwater ecology, and fish biology.
