O
An observation represents the full suite of phenophase responses for an individual plant or species of animal, at a site, on a given day. So, if you reported observations on three red maples, a robin and a bumblebee, today, you'd have made five observations (in the way that we're defining them here).
A YES or NO answer reported for each individual phenophase within a suite of phenophases per species.
A short, prostrate shoot arising from the base of a plant
Plants or plant species that display an opportunistic response to environmental variations in resource availability, such as species that leaf out when water is available and drop their leaves when stressed - repeatedly, or flowering unpredictably a second time later in the season when water is available during the warm months
Leaves and branches arranged along a twig or shoot in pairs, opposite each other at a single point (stem node) along a stem or axis
The spotaneous diffusion of liquid through a semipermeable membrane (such as a cell wall) in a direction that will equalize solute concentrations on both sides of the membrane. Describes the physical process in which any solvent moves, without input of energy. This is the process by which water is drawn from the soil up into the roots of a plant and transported, and moved in and out of cells (compare with active transport).
The part of the pistil that contains the ovules
Describes the position of the ovary in a flower relative to the whorls of the perianth (calyx/sepals and corolla/petals). A superior ovary describes an ovary that sits above where the perianth is attached to the floral structure; an inferior ovary describes an ovary that sits below the point of attachment of the perianth and stamens - and are attached at the top of the ovary, with the exposed style and stigma ; a perigynous ovary describes an ovary that is surrounded by floral parts (a calyx tube) that is attached to the perianth and stamens around the ovary, but not attached - making the ovary appear more or less half exposed .
The haploid body which, after fertilization, becomes a seed/propagule
