Introduction

This year marks a significant milestone in the world of comparative physiology—the 100th anniversary of the Journal of Comparative Physiology A (JCPA). Founded by Karl von Frisch and Alfred Kühn in 1924, the journal has been a cornerstone in the field, fostering groundbreaking research and shaping the trajectory of neuroethology. To celebrate the 100th anniversary of JCPA, and the contributions of its numerous authors, the journal published a Centennial Issue with 15 articles featuring historical overviews, personal essays, expert reviews, and a perspective piece venturing some predictions about potential trends in neuroethology.

The celebration of JCPA at a glance

A look back at the history of comparative physiology and its premier journal
In its infancy, the journal started modestly with a few articles, but under von Frisch's editorship, it quickly gained renown. Over the years, JCPA has been instrumental in reporting landmark discoveries and nurturing a vibrant community of scientists in comparative physiology and neuroethology. The special issue also pays tribute to key figures beyond von Frisch, highlighting lesser-known pioneers such as Ruth Beutler and Ingeborg Beling, whose groundbreaking work paved the way for future generations.

Personal Reflections on JCPA
Renowned neuroethologists, including Eric Warrant and Horst Bleckmann, share personal anecdotes about their careers and the profound impact of JCPA on their research journeys. Their stories offer a glimpse into the deep connection between scientists and the journal that has shaped their scholarly pursuits.

Exploring Research Trends
The special issue delves into popular and emerging topics in comparative physiology, from model systems to insect-plant interactions and avian navigation. Authors advocate for studying non-traditional model organisms and propose innovative approaches to understanding complex biological phenomena. Get direct access to the articles below:
