J Exp Biol jeb.242428.
Published: 06 May 2021
...Maxwell L. Zhu; Kristian J. Herrera; Katrin Vogt; Armin Bahl Navigating across light gradients is essential for survival for many animals. However, we still have a poor understanding of the algorithms that underlie such behaviors. Here we develop a novel closed-loop phototaxis assay for Drosophila...

...Olivier J.N. Bertrand; Charlotte Doussot; Tim Siesenop; Sridhar Ravi; Martin Egelhaaf One persistent question in animal navigation is how animals follow habitual routes between their home and a food source. Our current understanding of insect navigation suggests an interplay between visual memories...

...Rickesh N. Patel; Thomas W. Cronin ABSTRACT Mantis shrimp of the species Neogonodactylus oerstedii occupy small burrows in shallow waters throughout the Caribbean. These animals use path integration, a vector-based navigation strategy, to return to their homes while foraging. Here, we report that...

... lead nestmates, one at a time, from the nest to the food. In this way, naive ants can learn the location of a food source. Less clear is whether they also learn navigational cues that guide them from nest to food, although this is often assumed. We tested this idea by tracing the routes of individually...
