ONE AND TWO PLANES. "When restricted to one plane or orientation, unbranched filaments can be formed (e.g. Spirogyra); when confined to two orientations, cell division can give rise to branched filamentous, monostromatic, or pseudo-parenchymatous tissue constructions (e.g. Stigeoclonium, Volvox and Ralfsia, respectively)." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

BIRDS. “The question of how migratory birds find their way during seasonal movements that may span thousands of kilometres, has intrigued researchers since the very beginning of scientific research into avian biology (Newton, 1896). The first scientific bird ringing experiments performed in the early 20th century showed that a considerable proportion of migratory birds return to their natal or previous breeding sites in sub sequent years.”" https://lnkd.in/deSpEM3 View in LinkedIn

PLANTS. “Very little is known about the effects of geomagnetic fields on plants. The present work was undertaken to answer the question whether plants can perceive the geomagnetic fields. Our findings show that the effects of magnetic fields on various responses in Arabidopsis thaliana result in a characteristic multi-peaked pattern in the stimulus-response curves with multiple maxima (peaks) and minima (valleys). These multi-peaked stimulus-response curves display a unique phenomenon in biology.” https://lnkd.in/dMgR_kx View in LinkedIn

BATS. "N. plancyi is able to detect the direction of a magnetic field even at 1/5th of the present-day field strength. This high sensitivity to magnetic fields may explain how magnetic orientation could have evolved in bats even as the Earth’s magnetic field strength varied and the polarity reversed tens of times over the past fifty million years.” http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0123205 View in LinkedIn

MAGNETITE. “The existence of magnetite crystal chains, which lead to a magnetically oriented swimming behavior in so-called “magnetotactic bacteria”, unequivocally proves that living cells can, in principle, synthesize magnetite that will align with the geomagnetic field. However, the magnetite crystals in these bacteria are not part of an active sensory system; they only lead to passive alignment.” https://lnkd.in/eUbuD-a View in LinkedIn
