Leatherback turtle in Atlantic Canada (Dermochelys coriacea) recovery strategy: chapter 13
Appendix A - Glossary
-
Amphipod:
-
A small flat-bodied crustacean of the order Amphipoda.
-
Bioaccumulation:
-
The accumulation of a substance, such as a toxic chemical, in the tissues of a living organism.
-
Biomagnification:
-
The increasing concentration of a substance, such as a toxic chemical, found in the tissues of a living organism as you move up the food web. Simple organisms such as algae can absorb and bioaccumulate minute quantities of a substance which are transferred through the food chain to higher living species such as fish, bird, etc. Biomagnification along a food chain will result in the highest concentrations of a substance being found at the top of the food chain.
-
Bycatch:
-
The harvest of fish or shellfish other than the species for which the fishing gear was set.
-
Carapace:
-
A bony or chitinous case or shell covering the back or part of the back of an animal.
-
Commensal:
-
Having benefit for one member of a two-species association but neither positive nor negative effect on the other.
-
Critical Habitat:
-
the habitat that is necessary for the survival or recovery of a listed wildlife species and that is identified as the species' critical habitat in the recovery strategy or in an action plan for the species.
-
Delisting:
-
The removal of a species from the list of species at risk following its recovery.
-
Endangered Species:
-
a wildlife species that is facing imminent extirpation or extinction.
-
Food Chain:
-
a community of organisms where each member is eaten in turn by another member.
-
Forage:
-
the act of searching for food and provisions.
-
Gene flow:
-
Transfer of genes from one population to another of the same species.
-
Gangion:
-
A short line attached to a trawl.
-
Groin:
-
a protective structure of stone or concrete; extends from shore into the water to prevent a beach from washing away.
-
Gyre:
-
a great, circular motion of water in each of the major ocean basins centered on subtropical high-pressure region, with circulation clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.
-

Necrosis:
-
Localized death of cells or tissues through injury or disease.
-

-
Pertaining to animals that live at the surface of the ocean, away from the coast.
-
PIT tag:
-
Passive Integrated Transponder tags are microchips that are injected into an animal's muscle tissues using a hand-held applicator gun.
-
Plastron:
-
The front, or ventral part, of the shell of a turtle.
-
Rookery:
-
A breeding colony of birds or animals.
-
Revetment:
-
A sloping surface of stone, concrete or other material used to protect an embankment, natural coast or shoreline against erosion.
-
Riprap:
-
A rubble sustaining wall, often used along shorelines to prevent erosion.
-
Seawalls:
-
A wall of stone, concrete, or other sturdy material, built along the shoreline to prevent erosion even by the strongest and highest of waves.
-
Seismic Exploration:
-
The use of seismic energy to probe beneath the surface of the earth.
-
Stewardship:
-
The wide range of voluntary actions that people are taking to care for the environment.
-
Telemetry:
-
The automatic measurement and transmission of data from remote sources, by radio or other means, for recording and analysis.
-
Upwelling:
-
A process through which cold and usually nutrient-rich waters rise from the bottom of the ocean to its surface.
