Traditional Shepherding and Transumance in the Cevennes
Transumance is the seasonal movement of animals from the lowlands to high pastures for the summer months. This article and images come from witnessing Transumance in the Cevennes each year and talking to Annie Lashermes whose flock it is. The tradition of Transumance goes back millennia. Richard Nissen Editor <<<<< Transumance routes A shepherd with…
Magnetoreception – the ability to sense the Earth’s magnetic field
David Keays is one of the mega stars of animal navigation research and has spent a life time trying to work out how magnetism might work. Here is a summary of his latest work: Magnetoreception is the ability to sense the Earth’s magnetic field, which is used for orientation and navigation. Behavioural experiments have shown…
Monarch Butterflies
Here is a link to Monarch Butterflies http://phys.org/tags/monarch+butterflies/ Editor’s remark I have difficulty understanding these results which suggest that Cryptrochromes are involved which I am fairly clear is impossible as there is not enough time for the quantum coherence to take place. Inclination compasses are very inaccurate as there can be huge changes locally due to…
Avian Compass Reloaded
http://www.2physics.com/2012/10/avian-compass-reloaded.html Please find this interesting piece entitled The Avian Compass Reloaded by Dagomir Kaszlikowski at the Centre for Quantum Technologies, Department of Physics, National University of Singapore. Kaszlikowski talks about the the quantum effect that is required to enable the Cryptochromes in the eye of the European Robin to be sensitive to the earth’s magnetic field….
Migration of Banded Stilts from Australia
There was a recent article in the media, including the New Scientist and the Times about the migration of the Banded Stilt, which seems to migrate very fast at short notice. The recent interest has been triggered by work done at Deakin University in Victoria Australia by Reece Pedler. Banded Stilts normally live on the…
Eyes are essential for magnetoreception in a mammal
