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

One hundred years of excellence: the top one hundred authors of the Journal of Comparative Physiology A

The Journal of Comparative Physiology A is the premier peer-reviewed scientific journal in comparative physiology, in particular sensory physiology, neurophysiology, and neuroethology. Founded in 1924 by Karl von Frisch and Alfred Kühn, it celebrates its 100th anniversary in 2024. During these 100 years, many of the landmark achievements in these disciplines were published in this journal. To commemorate these accomplishments, we have compiled a list of the Top 100 Authors over these 100 years, representing approximately 1% of all its authors. To select these individuals, three performance criteria were applied: number of publications, total number of citations attracted by these articles, and mean citation rate of the papers published by each author. The resulting list of the Top 100 Authors provides a fascinating insight into the history of the disciplines covered by the Journal of Comparative Physiology A and into the academic careers of many of their leading representatives.

Olfactory navigation versus olfactory activation: a controversy revisited

In the early 1970s, Floriano Papi and colleagues proposed the olfactory-navigation hypothesis, which explains the homing ability of pigeons by the existence of an odor-based map acquired through learning. This notion, although supported by some observations, has also generated considerable controversy since its inception. As an alternative, Paulo Jorge and colleagues formulated in 2009 the olfactory-activation hypothesis, which states that atmospheric odorants do not provide navigational information but, instead, activate a non-olfactory path integration system. However, this hypothesis is challenged by an investigation authored by Anna Gagliardo and colleagues and published in the current issue of the Journal of Comparative Physiology A. In this editorial, the significance of the findings of this study is assessed in the broader context of the role of olfaction in avian navigation and homing, and experiments are suggested that might help to finally resolve the olfactory-navigation versus olfactory-activation controversy.
