English: Committee on the Status of Endangered Wildlife in Canada, which determines the detailed national status of wild Canadian species, subspecies, and separate populations suspected of being at risk craniate vertebrate: vertebrate with a skull crustaceans: diverse subphylum of arthropods, which have two pairs of antennae, one pair of mandibles (mouth-parts used for seizing and cutting food), and two pairs of maxillae (limb-link structures located behind the mandibles used when eating) ecosystem: a community of organisms interacting with each other and with their physical environment ectothermic: having a body temperature determined primarily by the temperature of the environment; cold-blooded; poikilothermic endemic: native to, and restricted to, a particular geographical region haploid: having only a single set of chromosomes endothermic: warm-blooded; maintaining a body temperature largely independent of the environment extant: existing or living at the present time extinction: elimination of a taxon (e.g., species) insectivore: feeding on insects extirpated: no longer in existence in a particular region, but still living in other areas of the world introduced species: see exotic species invertebrate: animal lacking a spinal column herbivorous: feeding on plants indicator species: a species, the presence or absence of which is indicative of a particular habitat, community, or set of environmental conditions general status: the numerical rank (ranging from 0 to 8) of a species as assessed in this report, based upon a series of criteria that capture information where available on population size and distribution as well as any trends (increasing or decreasing) in these attributes, and any known threats to populations or their habitat; species received a general status rank in each province, territory, or ocean region in which they are known to be present, as well as an overall Canada-wide general status rank geographic distribution: the current area contained within the shortest continuous imaginary boundary that can be drawn to encompass all the known, inferred, or projected sites of occurrence, excluding cases of vagrancy and significant areas where the species does not occur habitat: the locality, site, and particular type of local environment occupied by an organism habitat fragmentation: the process of dividing a continuous habitat into non-continuous, smaller subunits exotic species: species that have been moved beyond their natural range as a result of human activity; in this report, Exotic species have been purposefully excluded from all other categories frond: leaf of a fern, which differs from a typical leaf in that it bears reproductive organs on its surface gamete: a mature reproductive cell (usually haploid), which fuses with another gamete of the opposite sex to form a zygote (usually diploid); the male gametes are known as sperm (spermatozoa), and the female gametes as eggs (ova) gametophyte: the haploid sexual phase of a plant, which exhibits an alternation of generations, from which gametes are produced, usually by mitotic division; the haploid gametophyte is typically formed by meiotic division of a diploid sporophyte
