NEIGHBOR EFFECTS. "The response of an individual along a resource gradient is very strongly influenced by its neighbours. While negative interactions through competition for the basic resources of space, light, minerals and water, and interactions through allelopathy, are well established." (Allelopathy is the production of chemicals to influence the growth of nearby plants.) http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

VAST DATA INPUT. "If there are about 15 environmental factors acting in differing degrees and affecting the perception of each other then the combination of possible environments in which any individual can find itself and to which it must respond is enormous. Thus, the necessity for learning rather than rote behaviour. Moreover, long‐ and short‐term responses to environmental variables will be different." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

PLASTICITY AND FITNESS. "Individual plants that express plasticity will more nearly approach the fitness objective than individuals that do not. But the error‐correcting mechanism must involve complex negative feedback mechanisms with versions of trial and error; that is, learning." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

NOT RIGID REFLEXES. "Phenotypically plastic mechanisms are not reflex responses...but depend on an ability to assess not only what tissues should alter (with the assessment influencing very early tissue development), but an ability to stop plasticity when sufficient change towards the optimal goal has been made." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

NICHE MEMORY. "Measurements show that the niche is individual to the genotype, not the species. On that basis it is likely that each individual plant will possess a unique niche memory to which it will attempt to match growth and development. The important feature is that information, which describes the fundamental niche, is present in the organism and can be accessed, thus representing a kind of long‐term (life cycle) memory." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

LONG-TERM DATA SETS. "Regulation of the saccharide metabolism may provide additional examples of integrating, storing and accessing information on long-term state of the plants' metabolism, including but not limited to the performance of the photosynthetic apparatus." https://lnkd.in/dfsCv77 View in LinkedIn

SO ENDS this first of two weekends contemplating the return to the sea of the seagrasses. Like the whales, these organisms have made this challenging reversal by numerous genetic, biochemical, anatomic, and physiological modifications, rendering them totally different from the creatures that first emerged from the sea to dry land. Their return was not simply a reversal of status, a return to how they were. It was more strenuous — by far — than the twisting of a vertical flatfish face horizontal. View in LinkedIn

COMPLEX DORMANCY. "We are also catching first glimpses of the complex web of hormonal and gene expression regulatory pathways controlling seed dormancy, as well as the intricate interplay of light-dependent signals such as phytochrome modification, circadian rhythms and phytormonones implicated in light-controlled developmental regulation." https://lnkd.in/dfsCv77 View in LinkedIn
