Research center | Contact | Photo album | Publications | CV

Research Interests

  • Tritrophic levels pollination
  • Role of fragmentation in plant and pollinators biodiversity
  • Pollination efficiency=what we measured and what does it mean
  • Sexual deception in orchids
  • Evolutionary ecology of pollen longevity and stigma receptivity duration
