# Ran Nathan

Ran Nathan (Hebrew: רן נתן; born 1962) is an Israeli biologist, ornithologist, and academic.
He is an ecologist who holds the Adelina and Massimo Della Pergola Chair of life Sciences at the Hebrew University of Jerusalem in the Department of Ecology, Evolution and Behavior where he leads the Movement Ecology Lab. Additionally, Nathan is the director of the Minerva Center for Movement Ecology and the co-founding co-Editor-in-Chief of the free-access journal Movement Ecology (BioMed Central).
His work focuses on various aspects of movement ecology, including dispersal (and long-distance dispersal in particular), migration, foraging, navigation, flight aerodynamics, animal behavior, social interactions, invasive species, disease spread by avian species, gene flow, plant-animal interactions and plant recruitment.

## Research interests
### Long-distance dispersal

Nathan's earlier work (since 1999) focused on seed dispersal, and long-distance dispersal (LDD) in particular. In a series of studies, he and his colleagues demonstrated the strength of the mechanistic approach in understanding seed dispersal and plant dynamics, as well as the importance of rare long-distance dispersal events in plants (Nathan 2006 Science), their underlying mechanisms and their role in determining spread rates of plants in future environments.

### Movement ecology

In an interview for Science Watch (October 2010), Nathan revealed that the idea to establish movement ecology as a new field of research was born in 2002, when he was a first-year faculty member supervising one student on seed dispersal and another on bird migration, facing the question “what name should I call my research group”? This has led him to wonder why different movement phenomena are studied in isolation from each other, and why there is still no general unifying theory of organismal movement. He then decided to call his research group "movement ecology", and later on noticed this term has already been used in the literature, but very occasionally at the time and never in the context of a unifying research paradigm.
In 2006, Nathan initiated and led an international group at the Israel Institute for Advanced Studies in Jerusalem which has set the foundation for development of the field of movement ecology as a new integration of movement research. In 2008, he edited a Special Feature on Movement Ecology for the Proceedings of the National Academy of USA. This collection included a perspective paper introducing the basic concepts and a framework for integrating movement research. In 2012, Nathan established the Minerva Center for Movement Ecology supported by the Minerva Foundation and the Hebrew University of Jerusalem as a German-Israeli interdisciplinary research center for studying movement ecology. Together with Prof. Sivan Toledo (Computer Sciences, Tel Aviv University), he developed a revolutionary wildlife tracking system called ATLAS (Advanced Tracking and Localization of Animals in real-life Systems), a portable, affordable tracking system capable of automatically and simultaneously tracking a large number of small animals (20 grams and less) in high accuracy and high sampling frequency. In 2013, Nathan co-founded a new open-access journal, Movement Ecology (BioMed Central), which has become a major forum for publishing studies on the movement of animals and plants.
