Definition: There is no evidence that the organism produces compounds (allelochemicals) that influence the growth, survival, and reproduction of other organisms.
Definition: The percentage of organic carbon divided by the percentage of total nitrogen in organic material is higher than 59.
Comment: USDA Plants database specifies the organic material as either the above ground biomass of an herbaceous plant or the above ground herbaceous material of a woody plant.
Definition: A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category.
Definition: A porosity quality inhering in a bearer by virtue of the bearer's being incapable of admitting the passage of gas or liquid through pores or interstices.
Definition: A porosity quality inhering in a bearer by virtue of the bearer's being incapable of admitting the passage of gas or liquid through pores or interstices.
Definition: Egg-shaped; a spheroid quality inhering in a bearer by virtue of the bearer's exhibiting a continuous convex surface with an axis of symmetry and one axis longer than the other.
Definition: A shape for a biological structure that approximates an ellipsoid. (eg: for a cell, see Table 1, Olenina, I., Hajdu, S., Edler, L., Andersson, A., Wasmund, N., Busch, S., Göbel, J., Gromisz, S., Huseby, S., Huttunen, M., Jaanus, A., Kokkonen, P., Ledaine, I. and Niemkiewicz, E. 2006.

Definition: Seed-bearing organ on gymnosperm plants. A type of fruit, usually woody, ovoid to globular, including scales, bracts, or bracteoles arranged around a central axis, especially in conifers and cycads.
Definition: A group of hydrous aluminium phyllosilicate (phyllosilicates being a subgroup of silicate minerals) minerals (see clay minerals), that are typically less than 2micrometres in diameter. Clay consists of a variety of phyllosilicate minerals rich in silicon and aluminium oxides and hydroxides which include variable amounts of structural water.
Definition: forests which are inundated with freshwater, either permanently or seasonally. They normally occur along the lower reaches of rivers and around freshwater lakes
Definition: A wetland that features permanent inundation of large areas of land by shallow bodies of water, generally with a substantial number of hummocks, or dry-land protrusions.
Definition: A color hue with medium-low wavelength of that portion of the visible spectrum lying between yellow and blue, evoked in the human observer by radiant energy with wavelengths of approximately 490 to 570 nanometers.
Definition: Of plant duration, a plant whose life span extends over more than two growing seasons, c.f. annual, biennial, ephemeral, of flowering with respect to architecture, hapaxanthic, monocarpic, pleonanthic
Definition: Of plant duration, a plant whose life span extends over more than two growing seasons, c.f. annual, biennial, ephemeral, of flowering with respect to architecture, hapaxanthic, monocarpic, pleonanthic
Definition: an inflorescence with a monopodial growth habit, composed at flowering stage of indeterminate, first order inflorescence axes and sessile, unisexual flowers each subtended by conspicuous inflorescence bracts
Definition: A convex 3-D shape quality inhering in a bearer by virtue of the bearer's resembling a cone (a 3-D shape with a round cross section that tapers).
Definition: substance or combination of substances that may be administered to human beings (or animals) for treating or preventing disease, or with the intent to make a medical diagnosis or to restore, correct or modify physiological functions.
