Long-Distance Nocturnal Navigator
Warrant11 2016 Here is a fascinating paper about The Australian Bogong Moth Agrotis infusa: which is the most amazing Long-Distance Nocturnal Navigator. As they navigate at night their feat is perhaps even more amazing than the migration of the Monarch butterfly in the USA. Richard Nissen editor Warrant E, Frost B, Green K, Mouritsen H, Dreyer D, Adden A, Brauburger K and Heinze S (2016) The Australian…
Oceanic navigation in Cory’s shearwaters:
Evidence for a critical role of olfactory cues for homing after displacement in open ocean. Procellariiformes are pelagic birds which wander in the open sea most of the year and often nest in remote oceanic islands. These birds are able to pinpoint their breeding sites following straight routes even if their nesting island is located…
The genetics of migration on the move
Intro to the paper >>>> This paper is important as it begins to investigate a genetic basis to animal navigation and focuses on finding markers to get a grip on understanding the underlying genetic architecture of migration Cross-breeding experiments were carried out in the 80/90s by Peter Berthold and his team at the Max Planck Centre in Seewiesen….
The best overview of the current ideas on Avian (bird) navigation, April 2012
By Professor Gary Ritchison of the University Works at Eastern Kentucky University in Richmond Ky, USA. His long-term interests have been in avian mating strategies, specifically examining factors that influence mate choice (and choice of extra-pair partners) by female songbirds and avian vocal behaviour (particularly the functions of song), the ecology and behaviour of grassland…
Another description of how animal navigation might work
In a recent address to RIN Dr Kate Jeffery of the Institute of Behavioural Neuroscience at University College London described a very complete structure for understanding animal navigation. See https://animalnav.org/navigation-networks-in-the-brain/ We at www.animalnav.org have been struggling with exactly these concerns. Prof Jeffery postulates that you need four things to create a navigation system A compass…
Olfactory landmarks and path integration converge to form a cognitive spatial map
This paper on olfactory landmarks is interesting as it covers the idea that the distinctive smell of a place can help navigation by creating a new landmark for helping an animal navigate. The recognition of a spatial landmark by its sensory features poses a problem for neural circuits. Fischler-Ruiz, et al. show how this problem…
