Biography

Eli Geffen is a behavioral ecologist currently interested in mammalian social interactions and vocal communication. He is also interested in population genetics, largely associated with conservation biology issues. He is currently studying vocal communication among male rock hyraxes, with emphasis on understanding the role of syntax in their songs

 

Research Interests

 

  • Behavioral ecology - social dynamics and vocalization in the rock hyrax, visual communication in chameleons, and evolution of sociality in canids and other carnivores.
  • Population genetics - behavioral and environmental factors that influencing dispersal decisions in carnivores and other vertebrates.
  • Comparative studies on various behavioral aspects of birds and mammals.
  • Eco-physiology - The effects of parasite load on breeding success in rodents.
