Research Interests:
Currently my major fields of research are in the area of Evolutionary Ecology, Aquatic
Ecology, Functional Morphology, Chemical Ecology, Behavioral Ecology, Population
Ecology and Marine Biology.
A major subject is the study of phenotypic plasticity in predator-prey model systems.
Phenotypic plasticity describes the property of a genotype to form different phenotypes in
response to different environmental conditions. As such it is central to the question how
traits are formed by the interaction of genome and environment. Our research on
phenotypic plasticity integrates many different subjects, e.g. behavioral studies,
biochemical analyses, life-history studies and functional morphological comparisons and
includes collaborative work on physical, genetic, proteomic and neurobiological questions.
Because we study ecological and evolutionary principles we are interested in working with
different species, which in turn allows to answer comparative questions. Our research area
ranges from marine over freshwater to terrestrial systems covering a species range from
protists to vertebrates.

Synopsis
Inducible defenses - those often dramatic phenotypic shifts in prey activated by
biological agents ranging from predators to pathogens - are widespread in the natural
world. Yet, research on the inducible defenses used by vertebrates, invertebrates, and
plants in terrestrial, marine, and freshwater habitats has largely developed along
independent lines. Ralph Tollrian and Drew Harvell seek to change that here. By
bringing together leading researchers from all fields to review common themes and
explore emerging ideas, this book represents the most current and comprehensive
survey of knowledge about the ecology and evolution of inducible defenses.
Contributors examine organisms as different as unicellular algae and higher
vertebrates, and consider defenses ranging from immune systems to protective
changes in morphology, behavior, chemistry, and life history. The authors of the
review chapters, case studies, and theoretical studies pinpoint unifying factors favoring
the evolution of inducible defenses. Throughout, the volume emphasizes a
multidisciplinary approach, integrating applied and theoretical ecology, evolution,
genetics, and chemistry. In addition, Harvell and Tollrian provide an introduction and a
conclusion that review the current state of knowledge in the field and identify areas for
future research. The contributors, in addition to the editors, are May Berenbaum,
Arthur Zangerl, Johannes Jaremo, Juha Tuomi, Patric Nilsson, Anurag Agrawal, Richard
Karban, Marcel Dicke, Ellen Van Donk, Miquel Lurling, Winfried Lampert, Simon Frost,
