=> Developing tools for nature conservation in light of land-use changes and climate changes, and ensuring their implementation on-the-ground
=> Identifying factors that determine population dynamics and biodiversity patterns in fragmented, heterogeneous and human-dominated landscapes
=> Linking different ecological levels: animal behavior, the dynamics of populations and metapopulations, community structures and biodiversity patterns in fragmented landscapes
=> Animal-landscape interactions: how the decisions taken by animals in response to landscape cues affect movement patterns, functional connectivity, and the sensitivity of species to habitat loss and fragmentation

In my research, I try to link different ecological levels: animal behaviour, population (and metapopulation) dynamics, community structures and biodiversity patterns. I continuously combine simulation models with field experiments, to obtain a better understanding of nature but first and foremost for deriving practical tools for conservation. While butterflies serve as a major focal group in my empirical work, my models address a variety of taxa including mammalian predators (e.g. Lynx), plants, and currently birds.
My work involves both theoretic and applied research, as well as monitoring and active participation in science-policy interfaces in an attempt to disseminate scientific knowledge into policy and management.

Ongoing and completed research projects
Since Oct 2009:
Taking part in SCALES project, which aims to assess how different man-made pressures on natural environments (habitat loss, fragmentation, climate change, land-use changes etc.) affect biodiversity across scales (from genetic to ecosystem level). Concommitantly, the project seeks to identify the means to match the scales of policies and management with the scales of ecosystem processes.
Main responsibilities within the project:
- assessing connectivity across spatial scales
- reviewing Population Viability analyses (PVAs) and the Minimum Area Requirement (MAR) of species
- developing dynamic models to assess range shifts of species in response to climate change
- methodologies for upscaling and downscaling
Since April 2009:
The monitoring scheme for butterflies in Israel: Leading the program together with Racheli Schwartz-Tzachor and Dubi Benyamini, within the activities of the Israeli Lepidopterists' Society.
2007 - 2009:
Developing an individual-based model to analyse functional connectivity for birds of the Atlantic forest in Brazil, within the Mata Atlantica (BioCAPSP) project.
2006 - 2007:
The life history, ecology and conservation of the critically endangered butterfly Apharitis cilissa (Lycaenidae) in Israel
2005 - 2007:
A campaign for the legal protection and conservation of butterflies in Israel
2005 - 2006:
Linking behavior and biodiversity for butterflies in agricultural landscapes; a study across the climatic gradient in Israel
