A arachnids - a class of mainly terrestrial Arthropoda (jointed legged invertebrates) in which the head and thorax are continuous. The head bears pedipalps and chelicerae but not antennae. There are four pairs of walking legs. Examples: ticks, spiders, mites, scorpions, etc. apiculate - ending in a short, sharp point adpressed - pressed closely against. With salamanders, the relative length of the limbs can be assessed by holding them closely against the side of the body and checking the distance separating them or the amount they overlap alkali - a hydroxide which dissolves in water to form a solution with a pH greater than 7; capable of neutralizing an acid. arid - describes a climate or habitat having a low annual rainfall of less than 250 mm, with evaporation exceeding precipitation, and a sparse vegetation amplexus - sexual intercourse in amphibians B beak sculpture - texture on the outer surface of the shell adjacent to the hinge Blue List - The provincial ranking system that designates species as sensitive or vulnerable and "at risk" but not yet endangered or threatened. Populations of these species may not be in decline, but their habitat or other requirements are such that they are vulnerable to further disturbance. Species that are generally suspected of being vulnerable, but for which information is too limited to allow designation in another category, are included in this category. burrow - an animal den in the ground C cerambycid - family of beetles - long-horned woodborers Conservation Data Centre (CDC) - an organization that compiles information on the status and occurrence of rare vascular plants, vertebrates, and plant communities. The purpose of the Data Centre is to centralize and standardize data, concentrating on rare animals, plants, and communities for a particular jurisdiction, such as British Columbia. CDC Rankings: G - global rank, based on the status of the element of biological diversity (such as species, subspecies, plant community or special biological feature) throughout its entire range S - provincial or subnational rank, based solely on the element's status within British Columbia H - historical occurrence; usually not verified in the last 40 years, but with the expectation that it may be rediscovered X - Apparently extinct or extirpated, without the expectation that it will be rediscovered ? - Limited information is available or the number of extant occurrences is estimated. U - Status uncertain, often because of low search effort or cryptic nature of the element; uncertainty spans a range of 4 or 5 ranks T - designates a rank associated with a subspecies 1 - Critically imperiled - extremely rare (5 or fewer extant occurrences or very few remaining individuals) or some factor(s) make it especially vulnerable to extirpation or extinction 2 - Imperiled - rare (typically 6-20 extant occurrences or few remaining individuals) or some factor(s) make it vulnerable to extirpation or extinction 3 - Rare or uncommon - typically 21-100 occurrences; may be susceptible to large-scale disturbances, such as loss of extensive peripheral populations. 4 - Frequent to common - greater than 100 occurrences; apparently secure but may have a restricted distribution or future threats may be perceived 5 - Common to very common - demonstrably secure and essentially ineradicable under present conditions calcar - in insects, a tibial spine cannibalism - predation of an animal by a member of its own species carnivorous - flesh eating COSEWIC - Committee on the Status of Endangered Wildlife in Canada - determines the national status of wild species, sub-species and separate populations in Canada based on the recommendation of individual status reports. All native fish, amphibians, reptiles, plants and animals are included and are ranked: Vulnerable, Threatened, Endangered, Extirpated or Extinct. Three lists are maintained: 1) species with designated status; 2) species examined and designated in the not at risk category; 3) species examined and designated in the indeterminate category because of insufficient scientific information. caudex - a trunk or stock costal - any riblike structure.
