BODY PLAN IRRELEVANT. "Although a number of growing point (meristematic) characteristics collectively influence whether a variety of morphological and anatomical features are achieved in a particular body part or plan (e.g. the duration of activity and the number of cells involved at each location, as well as the extent to which cells, tissues or organs differentiate or differ in symmetry, number, etc.), none of these features is considered here to be especially relevant to the fundamental distinctions that can be drawn among the four basic plant body plans." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

MULTIPLICITY FROM SIMPLICITY. "Since each of these three multicellular variants can involve diffuse, trichothallic, intercalary, or apical cell divisions, or some combination of all four, a large number of multi-cellular body plan variants can be codified (i.e. 3 cell division planes, 5 meristematic locations, 15 variants de minimis), although the usefulness of doing so is questionable." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

MAGNETIC GUIDES. “It has been clearly demonstrated that birds are able to sense the compass direction of the Earth’s magnetic field and that they can use this information as part of a compass sense. Magnetic information could also be useful as part of a map sense, and there is a growing body of evidence that birds are able to determine their approximate position on the Earth on the basis of geo-magnetic cues.” https://lnkd.in/eUbuD-a View in LinkedIn

GREAT MIGRATIONS. “The monarch butterfly is able to migrate thousands of miles across the North American continent, a journey so long that it incredibly requires at least two generations to complete it! No less baffling is the migratory behavior of some other animals: for example, the Manx shearwater, a fast-flying seabird, that can glide and plane its way to breeding grounds across the Atlantic Ocean, and the Pacific salmon that returns to the very stream where it was hatched after 2 years of wandering thousands of miles at sea.” https://lnkd.in/d5Zy7J8 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
