The vector of the geomagnetic field provides animals with directional information, while intensity and/or inclination provide them with positional information. For magnetoreception, two hypotheses are currently discussed: one proposing magnetite-based mechanisms, the other suggesting radical pair processes involving photopigments.

Magnetic particle-mediated magnetoreception [PDF]
Journal of the Royal Society Interface, 2015 Behavioural studies underpin the weight of experimental evidence for the existence of a magnetic sense in animals. In contrast, studies aimed at understanding the mechanistic basis of magnetoreception by determining the anatomical location, structure and function of sensory cells have been inconclusive. In this review, studies attempting to demonstrate

Science, 1994
Magnetoreception by honeybees ( Apis mellifera ) is demonstrated by such activities as comb building and homing orientation, which are affected by the geomagnetic field. In other magnetoreceptive species, iron oxide crystals in the form of magnetite have been shown to be necessary for primary detection of magnetic ...

Magnetite-based magnetoreception
Current Opinion in Neurobiology, 2001Orientation, navigation, and homing are critical traits expressed by organisms ranging from bacteria through higher vertebrates. Sensory systems that aid such behavior have provided key selective advantages to these groups over the past 4 billion years, and are highly evolved; magnetoreception is no exception.

Journal of Plant Research, 2005
This article reviews phenomena of magnetoreception in plants and provides a survey of the relevant literature over the past 80 years. Plants react in a multitude of ways to geomagnetic fields-strong continuous fields as well as alternating magnetic fields.

Shedding Light on Vertebrate Magnetoreception [PDF]
Neuron, 2002 We review the challenges and recent progress in elucidating the physiological basis of animal magnetoreception. Behavioral and theoretical studies suggest a link between photoreception and magnetoreception in some animals. Neurophysiological studies have the potential to prove this link and identify the location of and the mechanism underlying the ...

In comparison to birds, magnetoreception in mammals has been understudied. This negligence has historical and methodological causes. Paradigms that have been applied in the study of magnetoreception in mammals (particularly, and among others, spontaneous or conditioned nest-building assay, magnetic alignment, maze studies and direction choice tests ...

Magnetoreception in birds and its use for long-distance migration
Sturkie's Avian Physiology, 2022The Earth’s magnetic field provides potentially useful information, which birds could use for directional and/or positional information. It has been clearly demonstrated that birds are able to sense the compass direction of the Earth’s magnetic field and
