ABSTRACT Many developmental biologists seldom leave the lab for research, relying instead on establishing colonies of traditional and emerging model systems. However, to fully understand the mechanisms and principles of development and evolution, including the role of ecology and the environment, it is important to study a diverse range of organisms in context. In this Perspective, we hear from five research teams from around the world about the importance and challenges of going into the field to study their organisms of interest. We also invite you to share your own fieldwork stories on the Node.
