Collaboration in the competitive world of science: lessons to be learned from William T. Keeton.

The tremendous increase in the number of authors and institutional affiliations on papers published in the natural sciences over the last few decades is commonly interpreted as an indicator of an increase in the collaborative spirit. However, a closer analysis suggests that this development reflects an increase in cooperation (defined as a strategy to divide labor among participants), rather than a rise in collaboration (defined as a mutual engagement of participants in a coordinated effort to jointly solve a problem). An exception to this development was William T. Keeton (1933-1980), who, as a faculty member at Cornell University, pioneered research into pigeon homing. A direct result of his willingness to openly share ideas and collaborate with other investigators is the article by Hagstrum and Manley (J Comp Physiol A, 2015) in this issue of the Journal of Comparative Physiology A. Their study is based on data from experiments Keeton and his collaborators conducted some 40 years ago. Despite the age of these data, their analysis and the interpretation of the results are likely to stimulate fruitful discussion in the field of avian orientation.
