Bats and Starfish

Here are two papers with a slightly different focus than our usual material, but both share some of the spirit of insect navigation research. Firstly, Vanderelst et al. have taken a sensory ecology approach to the study of place recognition in bats. Using detailed descriptions of the likely sonar signatures of complex scenes they were able to show how the complex signatures inherently contain the information required for navigation, potentially using insect like strategies. This paper reminds me of the seminal Zeil et al., 2003 JOSA paper which perhaps could be said to be the beginnings of a more formal approach to sensory ecology in insect navigation studies.

The second paper from Sigl et al shows that starfish use their compound eyes to identify and target reef structures. Previously it had been assumed that starfish would rely on chemoreception, however it seems vision is more reliable in certain situtations.
