Research

My lab focuses on the ecology and evolution of interspecific interactions, particularly on mutually beneficial ones (mutualisms). My career-long goal has been to build a solid conceptual foundation for the study of these poorly understood interactions. Using a combination of field observations, experiments, and theory, the Bronstein lab is examining how population processes, abiotic conditions, and the community context determine net effects of interactions for each participant species. Specific conceptual areas of interest include: (i) conflicts of interest between mutualists and their consequences for the maintenance of beneficial outcomes; (ii) the causes and consequences of "cheating" within mutualism; (iii) context-dependent outcomes in both mutualisms and antagonisms; and (iv) anthropogenic threats to mutualisms. With colleagues, I am extending these concepts to explore cooperation and conflict within business and educational “ecosystems.”
