Abstract

Long-distance navigation and magnetoreception in migratory animals Mouritsen H. Long-distance navigation and magnetoreception in migratory animals. Nature. 2018 Jun;558(7708):50-59. doi: 10.1038/s41586-018-0176-1. Abstract For centuries, humans have been fascinated by how migratory animals find their way over thousands of kilometres. Here, I review the mechanisms used in animal orientation and navigation with a particular focus on long-distance migrants and magnetoreception. I contend that any long-distance navigational task consists of three phases and that no single cue or mechanism will enable animals to navigate with pinpoint accuracy over thousands of kilometres. Multiscale and multisensory cue integration in the brain is needed. I conclude by raising twenty important mechanistic questions related to long-distance animal navigation that should be solved over the next twenty years. ncbi.nlm.nih.gov

Main findings

Narrative review of mechanisms used in animal orientation and navigation, focusing on long-distance migrants and magnetoreception. Argues that long-distance navigation involves three phases and requires multiscale, multisensory cue integration rather than any single cue/mechanism; highlights mechanistic questions for future research.
