Research Interests:

I am an ecologist with experience in both basic and applied ecology including studies on man-wildlife conflicts, especially within nature reserves. My professional experience in basic ecology is on plant-animal interactions, focusing on the role of secondary metabolites in fruits, seeds and nectar on bird nutrition, seed dispersal, pollination and plant fitness. These studies combine field work in Israel and other countries around the Mediterranean basin as well as in North America, Australia and South Europe and experiments with captive animals in Israel that include invertebrates such as ants and vertebrates such as birds of various species, rodents, gazelles and fruit-bats. The research on applied ecology includes wildlife management, natural reserve policy and ecosystem services, especially in Mediterranean ecosystems.


Specific research interests:

  1. The role of secondary metabolites in nectar and fruits in shaping plant-animal-bacteria interactions and plant fitness.
  2. Evaluating ecosystem services.
  3. Conservation of biodiversity in natural and man-made habitats.
