定義: Common species and uncommon species are designations used in ecology to describe the population status of a species. Commonness is closely related to abundance. Abundance refers to the frequency with which a species is found in controlled samples; in contrast, species are defined as common or uncommon based on their overall presence in the environment. A species may be locally abundant without being common.
定義: Living in the fluid medium (water or air) but unable to maintain their position or distribution independently of the movement of the water/air mass (adapted from Lincoln et al., 1998).
定義: (equivalent to ‘bottlebrush’) describes branching where sub-branches radiate in all directions from main branches and where corallites on sub-branches are generally elongate. Applied only to the genus Acropora
定義: Capable of the biological process in which new individuals are produced by either a single cell or a group of cells, in the absence of any sexual process.
定義: A group of species that exploit the same food resources, and/or use the same feeding or foraging methods. http://en.wikipedia.org/wiki/Guild_(ecology)
