Primary interests

Dr. Juanes’ area of research is ecology, evolution and behavior of fishes and benthic crustaceans. Particular interests include: the mechanisms leading to recruitment variability of marine fishes; the evolution of life history strategies, particularly with reference to the onset of piscivory in fishes; behavioral ecology of piscivorous fishes and decapod crustaceans, foraging theory specifically as it applies to prey size selection, and the allometry of animal spatial distributions.

Current Projects

  • Soniferous fishes of the Hudson River
  • Using passive acoustics to Determine Spawning Time and Fecundity of Haddock
  • Bluefish ecology and life history
  • Predator-prey dynamics of Georges Bank fishes
  • Reproductive ecology of cod and haddock
  • Dispersal of salmon fry
  • Conservation genetics of salmonids
