TL;DR: It is shown theoretically that fields of geomagnetic field strength and weaker can produce significantly different reaction yields for different alignments of the radical pairs with the magnetic field.

TL;DR: The structural, photochemical, and molecular properties of cry-DASH, plant, and animal cryptochromes are reviewed in relation to biological signaling mechanisms and common features that may contribute to better understanding the function of cryptochromaes in diverse systems including in man are uncovered.
Abstract: Cryptochromes are flavoprotein photoreceptors first identified in Arabidopsis thaliana, where they play key roles in growth and development. Subsequently identified in prokaryotes, archaea, and many eukaryotes, cryptochromes function in the animal circadian clock and are proposed as magnetoreceptors in migratory birds. Cryptochromes are closely structurally related to photolyases, evolutionarily ancient flavoproteins that catalyze light-dependent DNA repair. Here, we review the structural, photochemical, and molecular properties of cry-DASH, plant, and animal cryptochromes in relation to biological signaling mechanisms and uncover common features that may contribute to better understanding the function of cryptochromes in diverse systems including in man.

TL;DR: The magnetic compass of European robins does not use the polarity of the magnetic field for detecting the north direction, so birds take the direction on the magnetic north-south axis for "north" where field lines and gravity vector form the smaller angle.
Abstract: The magnetic compass of European robins does not use the polarity of the magnetic field for detecting the north direction. The birds derive their north direction from interpreting the inclination of the axial direction of the magnetic field lines in space, and they take the direction on the magnetic north-south axis for "north" where field lines and gravity vector form the smaller angle.

TL;DR: In this paper, the magnetic effects on spatial behavior in various groups of the animal kingdom from platyhelminths to vertebrates, with an emphasis on birds as the best studied group.
Abstract: This text details animal orientation with the help of information from the geomagnetic field. It reviews the magnetic effects on spatial behaviour in the various groups of the animal kingdom from platyhelminths to vertebrates, with an emphasis on birds as the best studied group. The discussion covers "compass" and "non-compass" effects and different types of responses, for example, alignments, compass orientation and orientation by the spatial distribution of magnetic parameters, which should aid the reader's understanding of the various ways magnetic information may be used.

TL;DR: Behavioral data from other animals indicate a light-dependent compass probably based on a radical pair mechanism in amphibians and a possibly magnetite-based mechanism in mammals, and Histological and electrophysiological data suggest a magnetites based mechanism in the nasal cavities of salmonid fish.
Abstract: Animals use the geomagnetic field in many ways: the magnetic vector provides a compass; magnetic intensity and/or inclination play a role as a component of the navigational ‘map’, and magnetic conditions of certain regions act as ‘sign posts’ or triggers, eliciting specific responses. A magnetic compass is widespread among animals, magnetic navigation is indicated e.g. in birds, marine turtles and spiny lobsters and the use of magnetic ‘sign posts’ has been described for birds and marine turtles. For magnetoreception, two hypotheses are currently discussed, one proposing a chemical compass based on a radical pair mechanism, the other postulating processes involving magnetite particles. The available evidence suggests that birds use both mechanisms, with the radical pair mechanism in the right eye providing directional information and a magnetite-based mechanism in the upper beak providing information on position as component of the ‘map’. Behavioral data from other animals indicate a light-dependent compass probably based on a radical pair mechanism in amphibians and a possibly magnetite-based mechanism in mammals. Histological and electrophysiological data suggest a magnetite-based mechanism in the nasal cavities of salmonid fish. Little is known about the parts of the brain where the respective information is processed.
